In mid-January, something called paper appeared on the markets of many islands. It was popular for its easy carrying and simple writing, and quickly replaced white silk as a new writing carrier.

Although paper is very expensive, it is still in short supply. The use of paper by nobles of major forces has even become a trend and a fashion. If you write a letter, you will be ridiculed by people.

On Chongming Island, the head of An family smiled. He thought that paper was a thing that made a lot of money, but he did not expect it to be so popular. There were 30 production points in the entire Chongming Island, and the output of a month reached tens of millions of large paper. After cutting it, it was 80 million pieces, but it was sold out in less than ten days, making a net profit of 50,000 stones. Even if he was comparable to the emperor of a country, such a speed of making money really made it difficult for him to calm down. You must know that this is a consumable and the money he earned is endless.

"According to this trend, we can recover our vitality in a short time. After losing thousands of experts, we have obtained the method of making grenades. Now there are a large number of Yuan stones that can be used for experiments. As long as we can find bombs, we are not afraid of killer whales." The head of the An family laughed and said to the prince of the An family sitting opposite.

The prince of the An family laughed when he heard this: "It seems that we didn't lose last time! I didn't expect that paper would be so popular... It's just paper now, and we can earn more when the cement comes out!"

"Yes!" The head of the An family nodded and said, "We should continue to increase production points! Otherwise, the monthly output will not be enough to sell!"

"Father, it's okay to increase the production point, but don't increase too much! It's not enough to sell it. Only in this way can we maintain a high price..." said the prince of the An family.

"What I said!" The head of the An family thought about it and thought that his son was right. The less this thing is, the more valuable it is. Once the price drops, it will be more costly.

"This time I can talk to the Presbyterian Church. Although I have lost a large number of experts, we have obtained more... and you are managing the production of paper and cement, and you are also doing the experiments on the bomb side. I think they should have nothing to say!" The head of the An family stood up and patted his son on the shoulder.

The prince of the An family was a little excited. He had lost his identity as prince for a year and was finally back... But he was about to speak, but he forced himself to hold it back. He shook his head and said, "Father, don't say it for the time being!"

"Don't you want to go back to your original identity?" asked the An family leader.

"Of course I want it! But not now, I have to wait for the cement to be launched, wait until the ancestor successfully returns from the ocean, wait for the bomb to be researched, and then take back what I lost in a blatant way!"

The prince of the An family had a calm expression and could not hear any fluctuations in his tone, but the An family leader knew that his heart was definitely suppressing his emotions at the moment.

"Okay! Just do what you said! But, the ancestor... are you sure?" asked the head of the An family.

"The ancestor's injuries have almost healed. There is no physical problem. It should be fine to go to the ruins in the ocean!" said the prince of the An family.

"But the danger is still very high, with storms in the ocean. There are many high-level monsters..." The head of the An family was a little worried.

"But as long as the ancestor enters the ruins, he may take the last step and achieve great perfection! If he really reaches that level, he will have the power to fight even when facing that level 27 bird!" The tone of the An family's prince was very firm.

The head of the An family took a deep breath and then said, "Okay! I agree, go and tell the ancestor!"

The prince of the An family curled his lips and nodded, "Okay! Don't worry, my father, the ancestor will definitely succeed!"

"Well! You have to hurry up, the grenade and the bomb work the same way, and try to get it out as soon as possible!" The head of the An family patted the prince of the An family again and stood up and left.

The prince of the An family left and returned to the secret room.

In the room, the ancestor of Chongming Island was still practicing martial arts, and he exhaled and inhaled his energy, and the entire secret room seemed to have a whirlwind.

The prince of the An family smiled: "The ancestor is completely ready!"

The ancestor of Chongming Island opened his eyes and looked at the prince of the An family: "I'm back, come here!"

"Old ancestor! I have something to tell you! I wonder if you have ever heard of the Dragon Pill?"

"What?" The ancestor of Chongming Island stood up suddenly, and the next moment he had already appeared in front of the prince of the An family, holding his shoulder tightly.

"Old ancestor, last time I escaped to the far sea and found a hidden picture..." The voice of the prince of the An family became increasingly weaker and weaker.

Not long after, the ancestor's laughter came from the secret room...

At the same time, far away on Sizhou Island, Wang Sun held a piece of paper in his hand and rubbed it gently.

"I really didn't expect that Chongming Island actually got the method of making paper!" His jealousy could be heard from Wang Sun's voice. Everyone knew that Xingchen had good things, and paper was one of them. No one was not jealous, and Wang Sun was the same. Especially after Jiang Xingchen knocked away 500,000 stones, he was quite tight. In addition, the complete failure of the Southern Wilderness, the situation around him was worse than the situation in the previous period of the An family's prince.

"Son of the King! We can earn this money too!" Manager Liu pushed the wheelchair forward and said carefully.

"What do you mean?" Wang Sun looked up at Manager Liu.

Manager Liu's heart trembled, he quickly lowered his head and whispered: "Our people sent back news on the mainland that Xingchenling has opened up papermaking and cement technology! And it has sold it to various countries, so we can buy it from them!"

Wang Sun thought for a while and said, "Do you think they will sell it to us? They all signed intellectual property rights, and now the Qiankun Empire is powerful, who do you think dares?"

Manager Liu said: "Son Wang, intellectual property has nothing to do with us! If there were no these two technologies overseas, they might have concerns, but now Chongming Island already has them. How can the Qiankun Empire know where our technology comes from! The Eight Kingdoms and Xuanyuan Tianzong have a grudge against the Empire again..."

"Where is money! What we lack the most now is money!" Wang Sun said again.

"Didn't you still have a Yuanshi Mine..." Manager Liu said, looking carefully at Wang Sun. Seeing that he was not angry, he continued: "Once we have these two technologies, the money we earn will be far more than that mine vein!"

Wang Sun pondered silently, and after a while, he made up his mind and nodded, "Okay! Just do it like that, you go and contact the seller immediately! I will arrange the mining of the mining veins!"

Wang Sun said as he got up and walked out strode. Manager Liu was proud, glanced at Yan He and the guard behind him, and left.

"Hmph! What's the pride? It's not certain whether it can be successful!" The chief guard sneered.

Yan He didn't say anything, just smiled faintly, and a glimmer flashed through his eyes...

It was soon the end of January, and the hot talk about the hot pot festival on the mainland gradually subsided. However, the star collar became more and more busy, and thirty-five kilograms of light rail were produced, with very standard shapes, specifications and sizes.

The transport team has also been assembled and is ready to transport these light rails to the Cursed Land at any time.

In the Lord's Mansion, Xian Ning was asking Jiang Xingchen what was behind the mathematics. Those things were too abstract and too difficult to understand! She was really surprised how Jiang Xingchen came up with these things.

These things seem to be just ordinary teaching, but Xian Ning knows that once it is based on research and development, the achievements it has achieved will be huge. This is not only an abstract mathematical concept, but also a key to opening up another kind of thinking. Taking a simple number axis as an example, it is enough to improve the current understanding of logarithm a lot.

Therefore, Xianning issued a strict order. These things cannot be spread for the time being except for teaching and self-research. Perhaps they need to be spread in the future, but they are not yet possible. At least they have to wait until all the frameworks are built.

Of course, the researchers also understood this truth and made all solemn promises!

In the room, Jiang Xingchen put down his notebook: "Let's stop here today, I have to sort out my ideas! How have you summarized the chemistry?"

"It is as you said, first classify the elements and compounds we know, and write the reactions and measured properties first... Chemical equations, I'm studying!"

"Hey! The foundation of chemistry is still too weak!" Jiang Xingchen sighed inwardly, and now he can only explore and move forward step by step. Moreover, the chemistry of this world is definitely different from that of the earth.

"Bang bang bang!" A knock on the door sounded, and Grandpa Fu's voice came from outside: "Sir, letter from the Wang family!"

"Xingchen, you're busy with your work first, let's do it today! I'll come to find you again when I go back!" Xianning stood up, went to open the door and let Grandpa Fu in, and then left.

Jiang Xingchen took the letter handed over by Grandpa Fu and opened it to watch it! After a moment, he laughed: "As expected, Chongming Island has developed papermaking and is making a lot of money overseas!"

Grandpa Fu sighed: "This is nothing to do, we really can't control overseas!"

"Who said I can't help it?" Jiang Xingchen sneered: "I gave Daqin, Dali, and the Moon Shadow Kingdom steam engine before, just to increase their output... Chongming Island wants to make money with my technology, it's not that easy!"

"Sir! You want to... fight with them in a lose-lose situation and you can't do it!" Grandpa Fu frowned.

"How could both sides suffer? We have a steam engine, and the production cost is much smaller than theirs..."

"I understand! I'll inform the Wang family now!"

After Grandpa Fu left, Jiang Xingchen sat on the chair and lowered his head to ponder. These days, Xingchen led the construction of steel rolling machinery, then iron and steel, and then rolled light rail. In addition, the cement and paper production side, the noise of the steam engine rotating at night can be heard.

"No, I have to do it this year. With the steam engine, the industry is developing too fast. If this continues, the stars will sooner or later become an industrial city!"

Just as he was thinking, he suddenly heard the old man’s laughter in his ears: “Boy, hurry up and prepare the new game for me. I will solve the question of the ancestor, hahahahahahaha…” (To be continued, please search for Astronomy, novels are better, updated and faster!

ps:  The garlic manuscript has been used up. I will write it again when I go home tomorrow afternoon. I guess both chapters will be uploaded at night. Brothers, don’t wait during the day! Sorry!
Chapter completed!
