After returning to the Eastern Palace, Li Chengqian ordered the guards to move the big wooden box and the sacks to his bedroom and left Zhang Gao, and all the other guards were sent out.

"Zhang Gao, since the ice water business cannot be completed, then you can find a few carpenters with better skills for me. Although the ice water business cannot be done, the ice cubes in the East Palace cannot be broken, and the ice cubes used by the two little girls also come out of our East Palace. If you find someone to find a place to burn more wood ash, I will be of great use.

There is also something tonight. You can give me instructions to you, and you can't tell anyone, even my Queen Mother and my father. If someone leaks a little bit of news, I will make him worse than death." After Li Chengqian, let Zhang Gao go out.

After leaving, Zhang Gao was sweating coldly. Although he didn't know what the things were, his master's final warning was definitely not just a joke. If the news leaked, it would be really over.

So after Zhang Gao came out, he quickly found all the guards who followed him today and warned them to keep their mouths tight. If anyone tells about what happened today, Li Chengqian would not have to come forward, and Zhang Gao would kill him.

"Hey, when I was in school, why didn't I learn chemistry well? Now I don't know how to make it with a soft steamed bun. I don't know how to do it, and I don't know how to do it, and I don't know how to do it, soap or something. What should I do?" After Zhang Gao went out, Li Chengqian lay in bed in annoyance, regretting why he didn't learn chemistry well before. Now that he has traveled through time, he can't even make baking soda and soap. This is completely embarrassing to Everbright Time Travelers.

"Wait, although I haven't learned chemistry well, but I have read so many time travel novels, I don't believe there is no useful information in it." Li Chengqian suddenly thought of something and lay on the bed and recalled the novels he had read before.

As he thought about it, Li Chengqian really thought that he would not be able to consume baking soda in chemical industry, but in nature, there is a lot of heat alkali in the sedimentary grounds of salt lakes. He could use these natural alkalis to make buns and steamed buns.

And that soap is also the same. Datang has alkalis. Although I don’t know what the alkalis are, as long as they are harmless to the human body, I can use them and oil to make soaps. Although it is slower and I have to try one, I can always make them.

But he knew nothing about other things such as how to make glass, how to burn ceramic tiles, and how to make cement. These are good things that can change people's lives and can also bring him a lot of wealth. He Li Chengqian would not.

"Madan, although I don't know these, I know they are either made of stones or sand. When I make enough money, I will definitely find craftsmen to experiment with a lot of experiments. If they don't work once, they will be twice. If they don't work a year, they will be two years. I still don't believe that I can't work it out. When the tiles and cement are finished, I will build a large open-air swimming pool first..." When Li Chengqian thought of the open-air swimming pool, he couldn't help laughing. After all, he loved swimming very much in his previous life. He dreamed of having his own open-air swimming pool, but as for the land price at that time, he just thought about it. But now when he came to the Tang Dynasty, he had this condition and he would never be willing to do it if he didn't work hard.

It took a long time to think about it. It was not until Xia Ju came to ask him and the bath water was ready that he remembered that he still had a bunch of good things waiting for him.

So after taking a shower, Li Chengqian drove all the palace maids out and told him that there should not be anyone within 500 meters of his bedroom, and that he could not say anything when he heard it. Then he came alone next to the large wooden box and sack he had found in the library.

"Today is a good day, what a good day..." Li Chengqian started singing happily before he could watch anything.

After all, the potatoes in the sack that he opened at the beginning could already make Li Chengqian excited for three days and three nights.

As for the things in other sacks and those in the wooden box, Li Chengqian actually didn't have any hope, because it was already an unexpected surprise to have a high-yield crop from other major states.

That's why he thought about other bad things after getting them.

But now seeing these potatoes, Li Chengqian was happy.

"Now let me see what the rest are." Li Chengqian opened several other sacks.

"My grass, God will not be so kind to me. It's really corn and sweet potatoes. With potatoes, I have all the best magic weapons and weapons for traveling through time. I'm not going to send them out. These things are good things, but they are useless to me. If I really take these things as my emperor's father, how could I let him depose my position as the prince?" After excitement, Li Chengqian quickly calmed down and opened the door of his bedroom to look around. After not finding anyone, he was glad that he was far away just now. In addition, although he was very excited just now, he didn't say it in a loud voice, otherwise his biggest secret would be known, and then he would be finished.

After confirming that there was indeed no one, Li Chengqian was worried about these high-yield crops. His identity was not a good thing to get potatoes, corn, and sweet potatoes, because as long as this thing was taken out and confirmed to be true, his position as the prince would be very stable.

But this is really not what Li Chengqian wants. The position of crown prince is stable, but the crown prince has to abide by it a lot, and this has been done for more than ten years.

When I think about being observed by countless people in the next ten years, I can’t make any mistakes, just to sit on the supreme throne, and think about Li Chengqian not wanting such a life.

So after thinking for a while, Li Chengqian decided to take out these high-yield crops when he was not the prince, or find someone to offer them to his emperor's father. Anyway, he would not come forward if he beat them to death.

However, Li Chengqian thought very well, but he forgot that man's calculations are not as good as God's calculations, and in the end he was found out by Li Shimin. Of course, this is a later story.

"I actually have potatoes and corn, so let me see if there is anything good in this wooden box." As he said that, Li Chengqian opened the wooden box in front of him.

However, after Li Chengqian opened the wooden box, he was stunned again, because the wooden box was covered with bags of seeds packed in cloth bags. As for what kind of seeds it was, Li Chengqian didn't know, but there was one thing he would never misread, that was dried peppers.

The kind of pepper that was not inherited from China until the Ming Dynasty is now lying quietly in the wooden box.

As a person who is not happy with spicy food, seeing it in this era when it is impossible to see chili peppers is really more exciting than seeing a peerless beauty. After all, he has been ready for this life and cannot eat chili peppers, but he did not expect to get it in this way.
