Glycerin has a wide range of functions, but its most widely used is to make nitroglycerin. I believe that later generations must be very familiar with nitroglycerin, and it is also involved with a very famous person, who is Nobel.

Zhu Yijun knew the principle and how to do it, so he naturally focused on more advanced gunpowder.

Black gunpowder has too many disadvantages, and it is basically impossible to make guns and cannons with greater power. To make guns and cannons, not only the steel industry needs to be improved, but also the gunpowder industry. Whether it is launching medicine or base fire, it all requires new processes, and it is not easy to meet the requirements.

Of course, Zhu Yijun, the glycerin produced now, was not intended to be used. He had to wait, eat the rice one by one, and walk the road step by step.

"Did you see this?" Zhu Yijun pointed to glycerin and said to Chen Ju with a smile: "This thing is called glycerin. It is very useful and can be used to make money. Fruits of different quality contain tannins of varying degrees, and tannins are the bitter and astringent source of fruits."

"Forget it, you don't have to remember what tannins are. Just remember that this glycerin can remove the bitterness and astringency of the fruit wine. It can enhance the thick and fragrant juice itself, with a bright appearance and a sweet and sour taste."

"In this way, after you go back, you can find a jar of fruit wine, and then try it yourself to see the effect."

Chen Ju nodded quickly, and his heart was shocked. He never expected that a bucket of lard, the emperor could use it to make soap, wax, and then produce this glycerin that removes the smell of wine.

Of course, I know that the thing is bitter and astringent, and it is very difficult to drink, which is far inferior to grain wine.

But the cost of fruit wine is low!

There are some things like fruits, all over the mountains and fields, and the cost of brewed fruit wine is very low. If it can really solve the problem of bitterness of fruit wine, the fruit wine will definitely be sold well. Chen Ju dared not think about how much profit it has.

"Do it well, make the transaction, and then you will have money!" Zhu Yijun said to Chen Ju with a smile, and after that, he turned around and left.

Zhu Yijun became idle again in the following days, and Zhang Juzheng was still cleaning up the officialdom and laying out his own reform plan. These had little to do with Zhu Yijun, and he was not ready to intervene, just watch it.

In July, a message sent by the East Factory attracted Zhu Yijun's attention and Yu Dayou was dismissed.

Since Zhu Yijun mentioned Yu Dayou last time, Zhang Jing has been paying attention to this matter. As soon as Yu Dayou was dismissed, Zhang Jing immediately ran to Zhu Yijun.

"Yu Dayou was removed from office?" Zhu Yijun looked at Zhang Jing and asked hesitantly: "Why did he be removed from office?"

"Go back to the emperor, the pirates raided Luxiao last month, and Yu Dayou was removed from office due to the failure of the war." Zhang Jing didn't dare to say anything, but just explained the matter clearly and presented the facts. This is the most effective for the emperor.

Zhu Yijun nodded. He knew that Yu Dayou was not going well now and had a lot of contributions, but he was always dismissed from office and was full of ups and downs.

Zhu Yijun naturally could not waste such a talent, so he said to Zhang Jing: "Let Yu Dayou enter Beijing!" After thinking about it, he said: "You Dongchang send someone to do it!"

"Yes, the emperor!" Zhang Jing nodded quickly. He finally breathed a sigh of relief. This time he had bet right, and this Yu Dayou was indeed highly valued by the emperor.

Zhu Yijun thought about it and felt that it was not possible. Yu Dayou was upright, so don’t misunderstand anything: “In this way, Dongchang sent a confidant to come over and you can’t leak the news. It’s a secret decree!”

"Do you understand that Yu Dayou pretends to be sick and then go to Beijing to find Dr. Li to see him. Do you understand?"

"The secret order is kept secret from outsiders, but you can tell Yu Dayou that I have to discuss confidential matters when I come to Beijing."

Zhang Jing felt aroused in his heart. Is the emperor of his family so cautious? He became cautious in his heart and nodded quickly: "Don't worry, I will do this and bring Yu Dayou to the capital."

Zhu Yijun nodded. He had wanted to find an opportunity to bring Yu Dayou to the capital.

Now Yu Dayou has been dismissed from office and the opportunity is just right. He brought him to the capital, planned for a while, and then found an opportunity to build a navy. If it really doesn't work, he quietly arranged him to Liaodong and then went there to build a ship and get a navy.

It’s OK with Jizhou, but there is Qi Jiguang’s territory there, so there may be problems.

Zhu Yijun didn't think of any good idea for a moment, but there were always ways. It would be serious to get people over first. Not to mention others, it would be good to treat Yu Dayou's health first, and let a famous doctor Li Shizhen treat him.

Yu Dayou is quite old, and with so many years of battles, he must have suffered a lot of physical injuries.

Repair it well and live a few more years. This is the kingly way. Only when he lives longer can he help himself build the foundation of the navy. Whether it is going south to suppress bandits in the future or going to sea to do business, it is impossible without a strong navy.

Not to mention the others, the largest pirate on the coast of Ming Dynasty, Lin Feng, can't beat the Ming navy at all.

Although Lin Feng was later wiped out, it was only after Lin Feng failed to fight against Manila and the Spanish, and that he was wiped out by the Ming navy. However, Lin Feng was wiped out, and another pirates emerged along the coast of the Ming Dynasty, and they were the pirate group headed by Zheng Zhilong.

Zhu Yijun has no good feelings for Lin Feng and Zheng Zhilong's pirate group.

To Zhu Yijun's opinion, it was basically nonsense to say that they prevented the Ming Dynasty from being colonized. With the strength of Spain and the Netherlands at that time, it was basically a fool to colonize the Ming Dynasty. Even if they harassed the coast, they would not have a good end.

These pirates have no bottom line. They went ashore to rob and colluded with Southeast gentry to smuggle, which can be said to be full of crimes.

Only when the imperial court had no navy and the imperial court was useless did they appear. Now that Zhu Yijun is here, he is preparing to build a navy and build a maritime fleet of the Ming Dynasty. These pirates must be cleared out as soon as possible.

First, we will restore stability to the southeast coast, and second, we will also cut off the smuggling path of the gentry in the southeast coast.

If they hold on to the sea trade, they don’t pay taxes, and Zhu Yijun has a way to let them spit out their money. Nothing is more profitable these days than sea trade. It can be said that it is a business without a lot. In many cases, doing sea trade and being a pirate means the same.

Zhu Yijun knows how to build a ship, but he doesn't know how to train troops, which is why he likes Yu Dayou.
