Glycerin had a wide range of uses, but the most widely used one was to make nitroglycerin.
He believed that the people of the future would be very familiar with nitroglycerin. Moreover, it was also related to a very famous person, and that person was Nobel Prize.
Zhu Yijun knew the principle, and he also knew how to do it. Naturally, he set his eyes on the more advanced gunpowder.
Black gunpowder had too many shortcomings. It was basically impossible to make more powerful guns.
To make guns, not only the steel industry needed to be improved, but the gunpowder industry also needed to be improved. Whether it was the propellant or the primer, they all needed new techniques. It was not easy to meet the requirements.
Of course, Zhu Yijun did not intend to use the glycerin now. He wanted to wait. He had to take things one step at a time.
"Do you see this?"
Zhu Yijun pointed at the glycerin and smiled at Chen Ju. "This thing is called glycerin. It is very useful and can be used to make money.
Different quality fruits contain different degrees of tannin, and tannin is the source of the bitterness and astringency in fruits. "
"Forget it. You don't need to remember what tannin is. Just remember that this glycerin can remove the bitterness and astringency in fruit wine.
It can enhance the rich taste and fragrance of the fruit juice. The appearance is bright, and the sweet and sour taste is palatable. "
"When you go back, find a jar of fruit wine and try it yourself. See the effect."
Chen Ju quickly nodded. He was shocked. He never thought that a barrel of lard could be used by the Imperial Majesty to make soap, wax, and even glycerin to remove the taste of wine.
Of course, Chen Ju knew about fruit wine. That thing was bitter and astringent, and it tasted terrible. It was far worse than grain wine.
But the cost of fruit wine was low!
There were fruits everywhere, and the cost of fermenting fruit wine was very low. If he could really solve the problem of bitterness of fruit wine, then the fruit wine would definitely sell well.
Chen Ju did not dare to think about how much profit there would be.
"Work hard and start a business, and then you will have money!" Zhu Yijun said to Chen Ju with a smile. After that, he turned around and left.
In the following days, Zhu Yijun was idle again. Zhang Juzheng was still tidying up the bureaucracy and making arrangements for his reform.
None of this had much to do with Zhu Yijun, so he didn't plan to intervene and just watched.
In July, a piece of news from Dongchang caught Zhu Yijun's attention. Yu Dayou was dismissed from his post.
Ever since Zhu Yijun mentioned Yu Dayou, Zhang Jing had been paying attention to this matter.
When the news of Yu Dayou's dismissal came out, Zhang Jing immediately ran to Zhu Yijun.
"Yu Dayou was dismissed?" Zhu Yijun looked at Zhang Jing and asked hesitantly, "Why was he dismissed?"
"Back to the Imperial Majesty, last month, pirates raided Luxia Ao, and Yu Dayou was dismissed because of his failure in the war."
Zhang Jing didn't dare to say anything more. He just made things clear and laid out the facts. This was the most useful thing for the Imperial Majesty.
Zhu Yijun nodded. He knew that Yu Dayou was having a hard time now. He had made a lot of contributions, but he was always dismissed from his post.
For such a talent, Zhu Yijun naturally couldn't waste it, so he said to Zhang Jing, "Let Yu Dayou go to the capital!" After thinking about it, he said, "Send someone from Dongchang to do it!"
"Yes, Imperial Majesty!"
Zhang Jing nodded quickly. He finally breathed a sigh of relief. This time he gambled correctly. Yu Dayou was really valued by the Imperial Majesty.
Zhu Yijun thought about it and felt that it wouldn't work. Yu Dayou was an upright person. Don't misunderstand anything. "Well, Dongchang will send a confidant there. The news can't be leaked. It's a secret decree!"
"Let Yu Dayou pretend to be sick, and then go to the capital to find Doctor Li to treat him. Do you understand?"
"The secret decree is confidential to outsiders, but you can tell Yu Dayou that I want him to go to the capital to discuss something confidential."
Zhang Jing's heart moved. Was the Imperial Majesty so cautious?
He also became cautious in his heart and nodded quickly. "Imperial Majesty, rest assured, Old Slave will do this well and bring Yu Dayou to the capital."
Zhu Yijun nodded. He wanted to find an opportunity to get Yu Dayou to the capital.
Now that Yu Dayou was removed from his position, the opportunity was just right. He could get him to the capital, plan for a period of time, and then find an opportunity to build a navy.
If it didn't work, he could quietly arrange for him to go to Liaodong and then build a navy there.
Jizhou was also fine, but it was Qi Jiguang's territory. He was afraid that there would be problems.
Zhu Yijun couldn't think of a good way for a while, but there was always a way. Getting him here was the right thing to do.
Not to mention others, it was also good to first recuperate Yu Dayou's body. Let the famous doctor Li Shizen recuperate him.
Yu Dayou's age wasn't young. With so many years of war, his body must have a lot of internal injuries.
Recuperate well and live a few more years. This was the way of the king. Only when he lived a little longer could he help himself to lay a good foundation for the navy.
Whether it was to go south to suppress bandits in the future or to go to sea to do business, it would be impossible without a strong navy.
Not to mention other things, just the biggest pirate Lin Feng along the coast of Daming, the navy of Daming couldn't beat him at all.
Although Lin Feng was later annihilated, it was only after Lin Feng lost the war against the Spaniards that she was annihilated by the navy of the Great Ming Dynasty.
However, after Lin Feng was destroyed, another group of pirates rose along the coast of Daming. They were the pirate group headed by Zheng Zhilong.
Zhu Yijun didn't have a good impression of Lin Feng and Zheng Zhilong's pirate group.
To say that they prevented Daming from being colonized was basically nonsense in Zhu Yijun's view.
With the strength of the Spanish Netherlands at that time, wanting to colonize Daming was basically a pipe dream. Even if they harassed the coast, they wouldn't have a good end.
These pirates had no bottom line. They went ashore to rob and colluded with the southeast aristocrats to smuggle. It can be said that they committed many crimes.
Only when the imperial court didn't have a navy and the imperial court was useless did they show up.
Now that Zhu Yijun came, he was ready to build a navy and was ready to build a sea fleet of Daming. These pirates must be cleaned up as soon as possible.
First, it was to stabilize the southeast coast and second, it was to cut off the smuggling road of the aristocrats along the southeast coast.
Holding the sea trade, they don't pay taxes, Zhu Yijun also has a way to make them spit out the money.
These days, there is nothing more profitable than sea trade. It can be said that it is a business without capital. Many times, sea trade and being a pirate have the same meaning.
Zhu Yijun knew how to build a ship, but he didn't know how to train soldiers, which is why he chose Yu Dayou.
