Chapter 6 Xuanzong's determination

"You're not lying, are you?" Princess Jinxian was a little disbelief and looked at Chen Wanrong.

"He has always been a lie." Princess Yuzhen said, and she also came to arrange Chen Wanrong's fault: "Sister, but this time, it should be the truth!"

"I seem to be a big liar?" Chen Wanrong was very upset.

"You are a liar!" Princess Yuzhen covered her mouth and couldn't stop laughing.

Ye Tianheng looked at the buret tube in Chen Wanrong's hand and said with a smile: "My friend, what strange things are you going to do? Tell us, don't swear everyone's appetite."

"Okay!" Chen Wanrong nodded, Ye Tianheng was very satisfied: "This is my friend!"

However, Chen Wanrong said: "I will also learn the ability of Master Ye to keep him indifferent. Please take a closer look!"

"You guy..." Princess Yuzhen looked at the burette in Chen Wanrong's hand with her wonderful eyes, and her eyes almost fell off: "You said so magical. When someone came to see you, you kept it in vain. You guys are so unreasonable."

Chen Wanrong put the sulfuric acid solution in the buret tube and fixed it on the rack, glittering at Princess Yuzhen: "I follow your master all day long, and I can't learn the ability to keep you inseparable. This is called "those who are close to the vermilion, and those who are close to the ink are black! Master Ye Tian, ​​there is nothing I can do about this!"

"My friend, what did you think I did?" Ye Tianheng felt embarrassed and smiled awkwardly.

Sima Chengzhen came out to smooth things over: "My friend, everyone is here to come to you for this analysis, you have to let us understand, you can't be confused, right?"

Chen Wanrong then looked solemn and explained seriously: "If you do business, you have a account and you have to calculate it clearly. The same is true for chemical engineering. You must know how much raw materials you use and how many products you get. You must also figure out the texture of the raw materials and products. Master Ye made steel and judged the grade of the ore by analysis, but by experience. This is not good."

Ye Tianheng was a little dissatisfied: "My friend, I haven't missed the steelmaking process yet. What's wrong with the experience? That's my secret skill."

Chen Wanrong raised his thumb and praised: "Master Ye is this, I am this, little finger. But when your master is away, don't you stop making steel? So, we have to find a way to turn these experiences into the way that people with my little finger can make steel. This is the function of analysis. As long as we know the texture of the raw materials, it will not be difficult to make steel. Similarly, when doing chemical engineering, you must first clarify the texture of the raw materials, and this analysis is very important."

"My friend mentioned this before. I spent so much energy on these small things just to analyze it?" Sima Chengzhen was quite excited and asked, "My friend, how do you analyze this?"

After returning from Tubo, Chen Wanrong made glass for chemical industry and asked Kou Yibing to make analytical instruments. After these days of hard work, he finally made the instruments that Chen Wanrong needed, and today is here to inspect.

"That's right, that's it!" Chen Wanrong explained after affirming, "We have spent a lot of time on Huo alkali. Today we will determine the purity of Huo alkali. It is not good to use sulfuric acid to determine Huo alkali. However, I only have sulfuric acid now, so I will just give it a try."

Hydrochloric acid is used to determine sodium hydroxide. Hydrochloric acid is out of reach for Chen Wanrong now, so I can only think about it. Let’s take a second best and use sulfuric acid. Fortunately, the current gallbladder is available, otherwise, there will be no sulfuric acid, let alone the measurement.

If current analysts knew that Chen Wanrong used sulfuric acid to determine the purity of turmeric alkali, he would definitely laugh at him, there was nothing he could do!

"The first step is to prepare the turtle alkali solution, which I made in advance." Chen Wanrong explained to them: "The preparation of the turtle alkali solution is very simple. You only need to put a certain amount of turtle alkali into boiling and cold boiling water. The water I use now is called distilled water, which is the water specially made a few days ago."

"You've been trying hard to make this? People thought you were fine after dinner, so they were looking for a slap!" Princess Yuzhen suddenly realized that she hadn't forgotten to arrange Chen Wanrong's wrong.

Chen Wanrong rolled her eyes: "Children don't understand adult affairs, don't talk nonsense."

"You? Who is the child?" Princess Yuzhen's eyes were almost falling to the ground.

Chen Wanrong laughed: "I'm taking a certain amount of hot alkali solution into the conical bottle." First put some water in the conical bottle, use a straw to take some hot alkali solution, and write down the number. Then adjust the sulfuric acid solution and fix it on the rack. Then add two drops of litmus indicator to the conical bottle, and the conical bottle suddenly turns blue.

"It's blue, it's blue!" Princess Yuzhen pointed at the cone bottle, a little unbelievable, screaming, and jumping up.

Princess Jinxian's eyes were also wide open, but she was quite persistent and didn't scream.

Ye Tianheng and the others were also curious and looked at the cone bottle in surprise. Sima Chengzhen smiled and said, "What a little trick is it!"

Those bad people rely on this change to cheat, so Sima Chengzhen is naturally familiar with it.

In their surprise, Chen Wanrong said, "I'm sure I'll start titrating." He put the conical flask under the dropper and started titrating. According to the regular analysis, the titration should be fast at the beginning, and it will only slow down when it reaches the end point. However, this requires calculation and you must be sure of it. Chen Wanrong has no bottom at all for the purity of the hot alkali used now. He cannot put it too fast and titrate it slowly.

Everyone's eyes were wide open, and they looked at the cone bottle in Chen Wanrong's hand without a single detail.

No one speaks, only breathing sounds.

After a while, the blue in the cone bottle gradually faded, and Princess Yuzhen was the first to shout: "There has been changes, there has been changes."

Chen Wanrong knew that it was almost time to reach the end, so he put the titration speed even slower. Drops of sulfuric acid solution dripped, and the blue color became lighter and lighter. Chen Wanrong changed to half-drop titration, and the last half-drop drips, and there was a little red in the cone flask. Chen Wanrong placed the cone flask on a piece of white paper, and the red became even more conspicuous.

Under normal circumstances, this color change is to be placed on a white tiles for observation. In the absence of white tiles, you can only use white paper. You just need to spread the white paper flat on the desktop.

The red was slowly fading away. Chen Wanrong knew that the end point had not arrived yet. After another quarter of the drop, the red became even more obvious. It was estimated that after half a minute, the red was still there. This was the real end point and it could be calculated.

After finishing the reading, the calculation according to the chemical equations showed that the purity of the alkali was only 83%. Chen Wanrong was so surprised. After using the purity of the alkali for so long and making so many soaps, the purity of the alkali was so low. No matter how poor the purity of the alkali in modern society was, it was more than 90%. This was too depressing.

Then I thought about it, this is normal. The alkali in modern society is obtained by electrolyzing salt water, called the chlor-alkali industry, with few impurities. Chen Wanrong obtained it by chemical reactions between soda ash and lime. The soda ash of the Tang Dynasty was crystallized by a natural salt lake, which itself contains a lot of impurities. Needless to mention lime, there are also many impurities.

The raw materials themselves contain a large amount of impurities. Although they are purified, the obtained alkali cannot be very purity, and it is still good to have 83% purity.

Another problem is that the analysis instrument is for trial use. It is hard to say whether it is easy to use, and it must be improved. This itself makes some problems with the analysis results.

As for the concentration of sulfuric acid, 98% of the concentration should be there, and there will be no problem. The sulfuric acid obtained from the alum has few impurities, and the concentration will not be low after repeated removal of water with zeolite.

In any case, this is the first time Chen Wanrong has learned about the purity of fire alkali after coming to the Tang Dynasty, and it is the first time to conduct analysis and measurement. This is a great progress in itself, and the direction of chemical industry has taken another step forward, which is worth celebrating.

"My friend, can you teach me?" Sima Chengzhen is a great alchemist and has a special interest in chemical engineering. When he saw the hunting, he rolled up his sleeves.

In Princess Yuzhen's eyes, this was really amazing and fun. I wanted Chen Wanrong to teach her, but after hearing this, I had to endure it. In any case, she could not disrespect Sima Chengzhen, who respected the world.

"It is my honor to be able to enter the eyes of Taoist priests." Chen Wanrong immediately pointed out. Under Chen Wanrong's guidance, Sima Chengzhen did it meticulously.

He is worthy of being a great alchemist. He has a strong foundation in this area and is actually doing it very well. Even if he is an analyst in modern society, he is not necessarily inferior to that of an analyst. Chen Wanrong secretly was surprised: "This is a beginner, and he has such a performance. If he gives him some time, that would be fine? By the way, in the future, I have to teach him more knowledge about chemistry and let him take on the burden of chemistry. Even if I am not here, it will not stop the chemical industry."

What Chen Wanrong didn't expect most was that Sima Chengzhen's analysis results were only 0.3 percentage points away from his results. Thinking about the first time when he was studying analysis, the standards of the teacher were actually more than one percentage point. Sima Chengzhen had such results for the first time, which was amazing.

Chen Wanrong's idea of ​​instilling more chemical knowledge into Sima Chengzhen was more firm.

Princess Yuzhen, who had been unable to control herself, said, "This thing is quite fun, teach me, okay? I won't say bad things about you in the future!"

Not to mention that Princess Yuzhen thought it was fun, even Ye Tianheng and the others were happy to see Lie, and wanted to try it. Thinking about the first time she did chemical analysis, her mood was not inferior to them.

"Okay! I've agreed that if you arrange my plan again in the future, I won't teach you what's fun." Chen Wanrong didn't take the opportunity to teach Princess Yuzhen a lesson, it would be useless.

"Okay, no problem. If you don't believe it, we can pull the hook!" Princess Yuzhen's eyes were so excited that she burst into flames.

At this moment, Gao Lishi's voice recalled: "General Chen, General Chen, are you here?"

Chen Wanrong knew that Gao Lishi was Li Longji's eunuch and would never leave for a moment. He must have had a big deal when he came. He hurriedly opened the door and saw Gao Lishi standing at the door and laughing, "Eunuch Gao, what's the point?"

Gao Lishi smiled and said, "General Chen, the emperor wants you to enter the palace immediately."

"I'll go now." Chen Wanrong followed Gao Lishi without saying a word.

Looking at Chen Wanrong's back, Princess Yuzhen was so angry that she stamped her feet: "There are so brothers. If you don't come early or late, you won't come here. It's my turn to send someone. It's boring! Oh, Taoist priest, can you teach me? Taoist priest, you are famous all over the world, you can learn this thing and you can get it right..."

A long list of flatteries came into Chen Wanrong's ears and couldn't help but feel funny. It was really unexpected that this Princess Yuzhen actually flattered Sima Chengzhen for fun.

"Eunuch Gao, what's the matter with the emperor?" Since sending away Geshu Han and the others, Chen Wanrong has devoted himself to building an analysis laboratory these days. The artillery training includes Wang Zhongsi, Wang Shaohua, Yang Sixu and Chen Zairong, so he almost doesn't have to worry about it.

Gao Lishi shook his head and said, "General Chen, General Zhang Shougui is back. He just entered the palace and the emperor asked me to come. I guess he should meet General Zhang!"

No matter how big or small the palace matters are, they must be disclosed to the public. Although Gao Lishi didn’t say much, it was already very rare. Chen Wanrong hurriedly thanked: “Thank you, my grandfather.”

Gao Lishi smiled and said, "This is not a big deal. If it were anything else, I wouldn't dare to say it."

He was a person who knew the rightness. Chen Wanrong didn't say much and went to the palace with him. When he came to Luanxiang Pavilion, there were only Li Longji, Yao Chong and a tall young man in the room.

"See the Emperor!" Chen Wanrong stepped forward to salute.

Li Longji waved and said, "I'm fine, come and sit down. I heard that you have made progress by focusing on that chemical analysis room these days?"

"Go back to the emperor, it's almost done." Chen Wanrong answered truthfully.

Li Longji can hear everything in detail: "Your idea is very good, and you must have a degree in everything. It's probably not impossible, but it depends on experience. It's too difficult to grasp. You can really analyze the accurate values ​​as you think, and it's much more reliable to do things. If you say it far, come and introduce it to you. This is Zhang Shougui. You meet."

With Princess Jinxian and Princess Yuzhen in the military weapon supervision, Li Longji naturally had the ability to monitor military weapon supervision without being surprised.

"I've met General Zhang!" Chen Wanrong greeted each other.

"I've seen General Chen!" Zhang Shougui returned the salute.

After the ceremony, the two of them took their seats again. Li Longji glanced at the three of them and said, "Today I brought you three to tell me what I thought. A battle next year will be crucial to the Tang Dynasty. I have thought about it over and over again and there are two strategies. Now, I will tell you, look at it, if there is any improvement, please point it out.

"Weapons are dangerous things! You must not be careless. If you have any ideas, you must say them out. I also remind you that I have never mentioned this idea to anyone, but I can only speak out from my mouth and into your ears, and not to others. Violators will destroy the clan!"

This is the highest military secret, and no one has any objection to this handling. However, Chen Wanrong was surprised: "Your Majesty, it is better not to know such a secret matter."

"If I ask you to listen!" Li Longji's face was solemn, his words were irresistible.

Chen Wanrong had to respond, and was very surprised: "Why did the emperor tell me about such a secret matter? Yao Chong was the prime minister of the dynasty. Although he was a civil servant, he also had military tactics. He knew it was natural. Look at this attitude, the emperor planned to let Zhang Shougui lead the three armies to fight, and he knew it was normal. But what about me? Is it more and more surprised?

Li Longji stood up, walked to the map, pointed to the map and said, "Since the rebellion, Mochu has 400,000 troops, controlled thousands of miles, and all the Turkic lands have returned to Mochu. The Huihe tribes who originally surrendered to the Tang Dynasty have also returned to Mochu. The desert is vast and has no obstacles. If you want to launch a fatal blow to Mochu on the desert, you must have hundreds of thousands of troops. Therefore, I decided to invest 500,000 troops in this battle next year."

He paused for a moment and said, "The army of 500,000 has not been seen in the history of the Tang Dynasty. It doesn't matter if it doesn't, just set a precedent!"

In the battle of Li Jing's destruction of the Turks, the Tang Dynasty dispatched more than 100,000 troops. After Wu Zetian counterattacked, the Turks sent up at most 450,000 troops, but nothing was found. Mobilizing 500,000 troops at one time was indeed unprecedented in the history of the Tang Dynasty.

This also shows Li Longji's determination: be sure to annihilate the main force of the Turks, Yongjing North!

"For the past thirty years, the Tang Dynasty and the Turks have been constantly fighting each other. Although they have won many victories and greatly defeated their spirits, most of them are defeated and their main force has not been annihilated. They have damaged their skin and bones, and the north are restless." Li Longji said: "I decided to take advantage of the Turks' opportunity to go south in the next year to annihilate their main force. Without the army, Mochuo even if he is an eagle on the desert, he will not fly above the nine heavens!"

"The emperor is wise!" Zhang Shougui praised: "I have been in the north for many years and I know how deep the Turks are. It is not that the Tang Dynasty could not defeat the Turks, but because the desert was vast, once the Turks were defeated, they would immediately escape, and the Tang Dynasty could not catch up even if they wanted to chase them."

The nomadic peoples have grown up on horseback since childhood, and they are skillful in riding and shooting, coming and going like the wind, and are fierce and swift. They can't beat them, and they can't escape immediately, but they can't catch up even if they want to. This is the strength of the Turks.

The disadvantage is that nomadic people only know how to turn horses and bend their bows, but don’t know what technology is. Some scholars jokingly say, “Technology is really too difficult for nomadic people!” This makes sense. They lack advanced technology, iron, and good organizational discipline. This is their weakness.

Once they encounter well-equipped and well-trained Chinese troops, they will only suffer a defeat. King Wuling of Zhao defeated the Hu people, the Huns, Qin Shihuang defeated the Huns, Emperor Wu of Han defeated the Huns, and Li Jing defeated the Dongjue!

The Chinese dynasty changed, one dynasty was destroyed, and another dynasty rose. Similarly, the same story was being staged in the desert, one nomadic nation fell, and another nomadic nation rose, but the stories they performed were the same. The Huns met the powerful Qin and Han armies, and the Turks met the warlike Sui and Tang armies, and they had to lose one after another.

The wealth created by the Song Dynasty far exceeded that of the Sui and Tang dynasties, and the technology was even more brilliant and brilliant, but it was really regrettable in front of the Khitan, Jurchen, and Mongolian alien races!

The same nation, which also has advanced technology and strong financial resources, cannot defeat the Khitan, Jurchen, and Mongolia, which are far inferior to the Huns and Turks, in terms of numbers, which are far inferior to those of the Huns and the Turks. This is an anomaly in Chinese history!
