Princess Taiping was very complicated about Yao Chong. She admired his outstanding political talent very much and wanted to take it for herself, but Yao Chong did not obey him. She tried to limit her everywhere, which made Princess Taiping unhappy and hated her when she remembered it. Sometimes, she wanted to kill Yao Chong immediately, but Yao Chong's political talent was rare, and Princess Taiping could not put her heart down.

Princess Taiping couldn't bear to kill Yao Chong; if she didn't kill, she felt so angry that she felt itchy when she didn't!

This is Princess Taiping's attitude towards Yao Chong. Now, Yao Chong not only returns to Chang'an, but also summons Ruizong. More importantly, as soon as Yao Chong appeared, he stole the limelight from his people like Dou Huaizhen and others and received encouragement from Ruizong, which made Princess Taiping very unhappy.

Yao Chong thanked him and sat down.

Ruizong glanced at everyone with a smile and said, "To tell you the truth, I am in a very good mood today! This is my happiest day since the great victory in Tubo! Do you know what the reason is?"

Chen Wanrong naturally knew that Ruizong was happy because he witnessed the magic of cement with his own eyes. With cement, roads can be built, and with smooth roads, the supply of the Tang army is more convenient, and the combat power of the Tang army is stronger. Ruizong, who is determined to be a great and capable king, can let go of his hands and feet and do a big fight.

Then, his achievements will come one by one. He will definitely be a very famous king in history, a wise and holy lord who is admired by future generations. This is the goal pursued by the emperor. Can Ruizong not be happy?

Dou Huaizhen and the others were not sure, so they looked at Ruizong for no reason. They saw that Ruizong had a glitter on his face and he was happy with his mouth open. This was an expression of unparalleled happiness.

"You can't guess it?" Ruizong was naughty, blinking his eyes and pointed to the concrete and said, "It's because of this! Yao Qing is right. This is man-made, not born by heaven and earth. This is made by Wanrong with a good craftsman in the military weapon supervision. This thing is a treasure! With this thing, the Tang Dynasty can build roads. Wanrong is the supervisor of the expedition to Tubo this time. Why did I call Wanrong back before the army even set up? It's just for this! Now, Wanrong has already made it, can I be unhappy?"

I yelled and celebrated every night, and I was so kind!

"Wanrong, it's better to tell you the purpose of this thing!" Ruizong sat back on the throne and looked at Chen Wanrong with great appreciation.

The person who knows the most about cement must be Chen Wanrong, and it is perfect for him to explain it. Chen Wanrong responded and walked to the concrete, glanced at everyone and said, "This thing can be called concrete, made of cement, sand, stone, steel bars and lime. These things that seem to be not closed together become this thing, because we have cement.

"The city walls of Chang'an are built with rammed earth, tall, wide, hard and durable. However, there is a problem with this, which is that they are easy to weather and need to be repaired from time to time. Rammed earth is widely used in daily life, and it is used from time to time to time to time for houses to be repaired. However, it is not used too much. For example, the palace does not use rammed earth to build palaces, but uses wood and stone to repair them. Why?"

Speaking of this, Chen Wanrong stopped and glanced at everyone. Dou Huaizhen smiled and said, "Everyone knows this problem, because rammed earth is easy to peel off and will fall from time to time. It is better to use wood to repair it. Also, rammed earth absorbs water very much and is very wet."

"What Master Dou said is very true! Master Dou knows that using concrete to build a house will not only not peel off, but will also be dry and clean, suitable for home furnishings." Speaking of this, Chen Wanrong said a little joke: "I originally thought that after I made the cement, I would build a small building by myself so that those who don't believe in it can see it. Now, cement is of great use, so I can only sigh."

Ruizong was very easy to talk to: "Wanrong, if you really want to practice, just build it. I want to build the road, and it is not that bad."

"Thank you, Your Majesty! However, I don't want to kill the backbone for others." Chen Wanrong politely declined Ruizong's kindness and said, "This was done yesterday afternoon. It has not been completely dry yet and has not reached the best. That's it, you can drive on it. You guys have touched it with your own hands. I don't need to mention its hardness."

He paused a little and said, "You must be surprised why sand, cement, lime and steel bars, such seemingly unrelated things have changed so much? The reason is that cement. We can make cement now, and soon, a large amount of cement will be made for the court to use. Oh, by the way, I would like to remind you: Don't ask how cement is made, and I won't tell you if you ask!"

At the end, there was a joke, and everyone burst into laughter. Princess Taiping's brows relaxed, and she pointed at Chen Wanrong and said, "Wanrong, you can really tell me!"

"Today, everyone is happy!" Chen Wanrong sat down.

Ruizong took over the conversation and said, "Wanrong has explained the purpose of cement, but it has not been explained in full. You just need to know so much. Today, I have summoned you here to discuss the matter of road construction with you. I have summoned Wanrong from Tubo to make cement. With cement, the Tang Dynasty can build roads. In the battle of Tubo, the Tang Dynasty won, but do you know how much hardship the soldiers suffered?

"It's because there is no good road! Supply and transportation cannot be carried. The artillery led by Wanrong carried the artillery for thousands of miles. Their shoulders and feet were not blistered and bleeding, but were bloody, and some artillery soldiers even saw bones. If there was a good road, would the soldiers suffer such hardship?"

The artillery carried the artillery across Jishi Mountain and rushed to the city of Doma. The entire Tang Dynasty spread all over the world. When the people mentioned artillery, they would give a thumbs up and praise the warriors! This is one of the reasons why artillery is very popular.

"I decided to build a road to Luosiecheng! In addition, I also built a road to the north and the western region. With these roads, the supply of the army will be greatly improved, and the border of the Tang Dynasty will be peaceful! Dashi will not be so rampant!" When Ruizong mentioned the word Dashi, his tone increased a lot.

Since the fall of the Eastern Turks and the Western Turks, the Tang Dynasty has not had a real opponent. Like Tuyuhun, Tubo was helpless in the Tang Dynasty, and Tuyuhun could only gather the border, and Tuyuhun was destroyed by the Tang Dynasty. When the Later Turks were established and harassing the northern part, they once faced Yunzhou (now Datong), and the troops pointed to the hinterland of the Central Plains. Overall, the national strength of the Later Turks was not as good as that of the Eastern Turks. They could only nuisance on the border, and there was no way to deal with the Tang Dynasty.

The Tang Dynasty had no choice but to deal with Dashi in the Western Regions! Dashi was the real opponent of the Tang Dynasty at that time! When it comes to Dashi, Ruizong's spirit was a bit stronger. He thought that if Dashi was defeated, it would be no less beautiful than Emperor Wu of Han defeating the Huns.

"You all tell me how to cultivate this path!" Ruizong said at last.

Everyone did not speak, but you looked at me, I looked at you, and thoughts quickly turned in your mind. You don’t need too high intelligence to think about it. This is a big event, a very wide range of things, you have to think about it carefully.

Ruizong did not urge them, but just looked at them quietly.

After a while, Xiao Zhizhong took the lead in speaking and clasped his fists at Chen Wanrong: "Mr. Chen, Xiao has a question to ask for advice, and I would like to ask Master Chen to explain his doubts to Xiao."

"I dare not ask for advice! Lord Xiao has something to say." Chen Wanrong was very surprised.

Xiao Zhizhong pondered for a brief moment and said, "Xiao did not object to the road construction. However, it was very difficult to build the road to Tubo. Lord Chen had been to Tubo. He knew that Tubo was high and far, the terrain was dangerous, and there were many mountains and steep mountains. If he wanted to build a city of Luoshe, he would definitely open mountains and fill valleys, and the people's power was consumed greatly. Can Lord Chen have a better way?"

Although Qin Shihuang built a straight road, although it was very useful, the people's power was also consumed. After a hundred years, Sima Qian followed the ruins of the straight road to investigate and was surprised. This was a very serious problem, which immediately aroused everyone's interest and focused on Chen Wanrong.

"Wanrong, if there is a better method, you must use it." Ruizong encouraged him a lot.

Chen Wanrong smiled and said, "What Lord Xiao said is very reasonable. It is inevitable to open mountains and fill valleys. Now it is much easier to build roads than before, because we have gunpowder. Gunpowder can not only be used as shells, but also be used to open mountains. When encountering huge rocks blocking the road, if there is no gunpowder, you can only need to smash it with hammers. With cannons, it is completely different. You only need to dig a hole, then put the cannon inside, install a wire, plug it tightly, and then ignite it to blow it up."

Everyone knows that gunpowder can be used to make shells, but no one thinks of this. When he hears this, he can't help but suddenly realize that a relaxed laughter sounds.

Chen Wanrong continued: "Gunpowder can also be used for mining. Haven't we always said that iron ore is not enough? It's much easier to use gunpowder."

The emergence of gunpowder not only promoted the development of the military, but also used for mining and road construction, providing great convenience.

"Okay!" Ruizong applauded with high fives. He knew about gunpowder, but he didn't expect gunpowder to have so many uses. It would be impossible to make him unhappy: "Then I will issue an order to mobilize the civilians and prepare to build roads."

"Your Majesty, I have something to say." Yao Chong, who had not spoken, suddenly said.

"Yao Qing, just say something." Ruizong really wanted to hear the words of Yao Chong, a wise man.

"Your Majesty, my words are a bit unpleasant. Please forgive me!" Yao Chong did not say anything directly.

"Haha!" Ruizong smiled happily and pointed at Yao Chong and said, "Yao Qing, if you say something nice, you are not Yao Chong, you are not capable ministers, you are a flatterer! Say it!"

Everyone knows that Yao Chong is loyal and will never say good things. Generally speaking, he will only find faults, which makes everyone smile.

Princess Taiping was unhappy with Yao Chong, Dou Huaizhen and others were very jealous of Yao Chong's extraordinary political talents, and they also had to admit Yao Chong's character.

As soon as he responded, Yao Chong began to talk about the serious matter: "Your Majesty, I do not object to the road construction. However, I think that in the current situation, it is not advisable to build three items, but should concentrate financial, human and material resources to build one, and pick up the most important ones to repair them."

Ruizong did not dare not ignore Yao Chong's words and asked hurriedly: "Yao Qing, which road do you think is the most important?"

Yao Chong replied: "Your Majesty, I think this Western Region is the most important."

"Yao Chong, is the road between Tubo and the Northland not important?" Princess Taiping seized the opportunity to question.

Yao Chongming knew that she was intentionally making things difficult for her, and ignored her, and then said, "The road to Tubo is important, but in comparison, it is not as urgent as the Western Regions. After this battle, even if Tubo has not been destroyed, it is equivalent to the death. Even if some people have bad intentions, it is difficult to cause trouble. First, the battle of Tubo killed almost the same people who wanted to fight against the Tang Dynasty. Second, the court implemented a new policy, and the Tubo people supported the Tang Dynasty. Even if some people wanted to cause trouble, they had no foundation. If what I expected was good, Tubo would not have any trouble within ten years. Ten years would be enough for the Tang Dynasty to do a lot of things!"

Chen Wanrong deeply agreed with this: "The emperor, I agree with what Lord Yao said. After a long time, I dare not say it, but I think that Tubo will be safe and sound for at least three to five years."

Among all, Chen Wanrong knew Tubo the most, and he said so, who would dare to object?

"Why is the road in the north not as important as the Western Regions?" Ruizong recognized Yao Chong's statement.

Yao Chong continued: "Emperor, I think the Turks are hateful and often disturb the border. I would like to ask the emperor, even though there have been any deeper national borders since the Turks rebelled, it can pose a huge threat to the court?"

After the establishment of the Later Turks, their national strength was far inferior to that of the Eastern Turks in their prosperous times, and they could not pose a substantial threat to the Tang Dynasty. After decades of fighting, there were almost no victory. As for the incident of the Yunzhou, it was a loophole. After the Tang Dynasty adjusted its military strategy, the Later Turks could only disturb the border.

Ruizong opened his mouth and couldn't speak. Yao Chong continued: "Besides, how many battles have the Turks won after decades of battle? The food, grass and weapons stored by the imperial court in the north are enough to use. I am not saying that I will not build this road, but that if it can be slowed down, it will concentrate all my strength to build this passage in the Western Regions."

Li Longji took over the conversation and said, "Father Emperor and Yao Chong said, my sons agreed. Since the battle of Tubo, the threat of Tubo to the Tang Dynasty has been basically lifted, and the court can concentrate its troops to fight him with a great victory. The Han army crossed the desert and directly attacked the Shanyuting, and Huo Qubing sealed the Langjuxu Mountain, which has become a legend for the ages. Without the restraint of Tubo, the Tang Dynasty can also cross the desert and directly attack the hearts of the Turks, and can get whatever they want in one battle.

"The Western Regions are different. As my sons know, Dashi is a powerful country. If there is no large army advancing westward, it is difficult to have a chance of victory."

In a word, even if the road is not built, the Tang Dynasty will still win.

Ruizong did not speak and pondered. Chen Wanrong said: "Your Majesty, Lord Yao also agrees. Some people say that one thing can only be done in a period. We have just successfully tried cement. If we want to make the cement needed by the court, it will not be possible for the time being. At least it will be difficult to do it within three to five years. If only one road is built, it can still be maintained."

After the technology is mature, there are still many things to do, including building equipment, building factories, and training craftsmen. After these things, it takes a lot of time to do them. To make the cement needed to build three roads at the same time, it is impossible for the military weapon supervisor to die of exhaustion.

In this regard, Chen Wanrong is an authority, and no one can refute what he said. Ruizong's enthusiasm was greatly hit. He thought for a while and said, "Since that's the case, let's first cultivate this Western Regions."

Yao Chong immediately said: "Your Majesty, I have some ideas about the path to the Western Regions, so I would like to ask the emperor to let me tell you."

"Yao Qing, say, say, say." Ruizong did not dare to stop Yao Chong's words. He wanted Yao Chong to say more.

Yao Chongying said, "Emperor, since Zhang Qian opened the Kowloon and the Fan, countless merchants have embarked on the road to the Western Regions and opened up the "Silk Road", which has played an extremely important role for thousands of years. However, this trade route can only be used for trade, not for military purposes. The reason is that some places on the Silk Road will change due to changes in deserts and oasis, which is very unfixed.

"Nevertheless, it does not mean that the Silk Road is useless. On the contrary, some places are fixed. If the imperial court wants to build roads, it should make good use of these fixed areas. My idea is that these fixed areas will not move first and invest our limited manpower and material resources in those areas that cannot be used. As long as these areas are repaired, the situation in the Western Regions will be greatly improved. Other parts will be renovated and reinforced when conditions are available.

"If this is true, the construction period of nearly ten years will only take one or two years to use it."

Ruizong's eyes shone brightly and he kept muttering to himself: "One or two years, one or two years..."

Without saying the following, everyone understands that "the Tang army can advance westward in one or two years and compete with the Dashi Empire for the Western Regions!"

This matter is so attractive! Ruizong naturally clenched his right hand into a fist and waved it hard!

Not only is Ruizong excited, but who is not excited? Chen Wanrong originally thought that he would concentrate all his efforts to build this road, not ten years of construction, but seven or eight years are always required. Yao Chong's idea can be completed in one or two years. This is amazing.

Of course, this kind of repair cannot fundamentally solve the problem, but it can also meet the requirements.

Not pursuing the best, only pursuing application is the law of reality!

Besides, we will first solve the important areas and then solve the other parts. In a few years, the road from Chang'an to the Western Regions will be a smooth road. More importantly, we will not be responsible for the Tang army's advance westward.

This is the wise man’s wonderful strategy!

"Okay!" Everyone praised in unison. Even Princess Taiping smiled and kept slapped her high-highlights.

Ruizong stood up excitedly and kept paced: "Yao Qing, your idea is really great, great! I want you to come, it's right. Think about it, we can use the road that originally took ten years to use in one or two years. In the past or two years, the court has to seize the time to solve the Turkic problem. Now, without the restraint of Tubo, the court can concentrate its troops and give the Turkic people a fatal blow!"

The battle of Tubo greatly improved the strategic situation of the Tang Dynasty. The troops that originally defended Tubo were no longer needed and could be transferred to the north. Later, the Turks had reached a critical moment of life and death.

"The emperor is wise!" Everyone praised it in unison.

Ruizong stopped and looked at Li Longji and said, "Sanlang, you have planned and dispatched the battle in Tubo. You will plan and dispatch the battle against the Turks next year."

Because of the battle of Tubo, Li Longji's reputation increased sharply and his foundation became more stable. Princess Taiping did not let Li Longji enjoy his enlightenment alone: ​​"Brother, I haven't done this war yet, so let my sister come and learn it."

"My sister, you don't have to interfere in this matter! What you need to do in a war is concentration. Once you come, it will cause differences. Let Sanlang do it. Sanlang can arrange the battle in Tubo well, and Sanlang will also do it well in this battle next year!" Ruizong waved his hand and directly rejected Princess Taiping's request.
Chapter completed!
