Li Zhen's legs are a little soft, and Zhu Wen is notoriously cruel. But he is really good to himself and Jing Xiang, he didn't expect to turn his face when he said that he would turn his face, and killing Jing Xiang was like killing a chicken.

Li Zhen felt a trace of fear, and he seemed to have a premonition that his future was dark. In the past, Li Zhenyi commanded angrily, and the Qingliu people trembled when they saw him, and it seems that he can live a long time by holding his tail between his legs in the future.

Zhu Wen was rewarded by his own soldiers in the Liang Palace: "Did Jing Xiang say anything?"

The captain of the pro-soldier bowed down and said, "King Qiliang, Jing Xiang didn't say anything, just shouted: Li Zhen can't die well."

Zhu Wen's heart moved: Li Zhen? Does Jing Xiang's provocation of Ge Jiajun have anything to do with Li Zhen?

……

Li Ji set up a stove in the palace and began alchemy, and now he has less surveillance. Zhang Mao is his own person, and Duan Hu also has a good relationship with him. The important thing is that the privy envoy Zhao Yan saw that he was respectful and responsive.

Zhao Yan's little pigtail was caught by Zhu Youneng since he raised the little pink, and he was also polite when he saw Li Ji, and he did the way of a monarch and a minister.

Li Ji was very satisfied, this guy knew that once he or Zhu You reported him about raising a concubine. With the nature of Princess Changle, Zhao Yan doesn't want to see the sun tomorrow.

The notice has been posted, and the emperor is recruiting,

The message is simple: anyone who has studied saltpeter and sulfur can do it, or anyone who is physically fit can do it.

Alchemy, it seems to be the same behavior as the brain-dead. Li Zhen scoffed, and Zhu Wen disdained, these were just Li Ji's actions to cover people's eyes.

Li Ji's real purpose was to study the formula of gunpowder, which only began to be used in the military during the Song Dynasty. In this era, except for some alchemists who pretend to be ghosts, no one knows the power of gunpowder.

What's worse is that Li Ji doesn't know, after crossing over, Li Ji found out what makes gunpowder, birds, cannons, it's pure nonsense, you can try it.

Although we have been educated in modern civilization, it is a cross-industry technical problem after all, and the devil knows how to develop gunpowder.

Fortunately, there is no rush in this, gunpowder should be relatively simple, and it is to explore it slowly.

Li Ji was most concerned about the recruitment of alchemists in the Imperial List. The requirements are very simple, one is to know the alchemy technique, and the other is to give priority to those with infinite strength.

Why do you want to choose the one with the most power, Li Ji really wants to cultivate his own power.

Looking at the entire palace, there are only two diehards, Youwei and Fuquan. Zhang Mao is just a guard who was surrendered by himself, if there is a change, who will jump out and desperately protect himself.

Only by cultivating one's own power can it be of great use at critical moments.

Now it is completely possible to summon some people from the rivers and lakes under the guise of alchemy, and then select dozens of diehards. Just like Kangxi captured Aobai, find an opportunity to take down Zhu Wen.

Of course, Zhu Wen is different from Aobai, and his influence is all over the capital. Even if Zhu Wen is arrested now, his subordinates will also rebel. Only when Zhu Wen's forces are slowly cut off and replaced with his own henchmen can he take risks.

Of course, this is a long process, and Mr. Mo Long said that Ge Congzhou will definitely return to obedience in less than a month, which Li Ji is not worried about at all. But after all, a small Ge Congzhou couldn't shake the tens of thousands of troops under Zhu Wen's command, so he could only take his time.

Youwei left the palace early in the morning, and he went to the Guangwang Mansion.

"What, Brother Li wants to do alchemy?" Zhu Youneng couldn't believe his ears, how could he still believe this.

Youwei nodded: "Your Majesty said that you should come to the palace."

Since he regarded Li Ji as a friend, Zhu Youneng felt that it was not interesting to do bad things alone, and it was fun for the two of them to be together.

For example, when you go to a casino, you are bored if you win. If it is with Li Ji, the two of them are blushing and shouting with thick necks, and they are happy to lose money.

finally found a friend with the same smell, Zhu Youneng was bored: "Okay, then let's go into the palace to have a look."

In fact, Zhu Youneng doesn't like to enter the palace very much, Li Ji is the emperor in the palace, and he has to abide by the etiquette of the monarch and ministers, so he can't call him Brother Li.

Fortunately, Li Ji is just a puppet, and there are not so many rules between monarchs and ministers in the Tang Dynasty, otherwise Li Ji may lose Zhu Youneng, a friend.

When Zhu Youneng came to the palace, he was really taken aback.

There is a huge copper furnace outside the Ming'an Palace, the charcoal in the furnace is red, and Li Ji is smoky and stir-frying something in the copper furnace.

The thing fried by Li Ji is called miscanthus salt, one of the materials used to make black powder.

When the nitrate scraping and sweeping (in the wall or in and out), into the tank water immersion for a night, the filth and miscellaneous things float on the surface, when the grabs away, and then into the kettle, water is poured into the decoction. The nitrified water is dried, poured into the vessel, and after a night, it is formed into nitrate. Those who float above it are called manganese,

"Your Majesty, what are you?" Zhu Youneng was taken aback.

Li Ji's face turned black, revealing a pat of white teeth: "Brother Zhu, come on, I will show you something interesting."

The manganese in the copper furnace was gradually dried, and Li Ji shoveled it out with a shovel and poured it into the clay pot, and there were three or four cans next to it that had already been fried.

Fuquan brought a basin of water and served Li Ji to wash his face. Li Ji looked at the several jars next to him proudly: "Brother Zhu, I will take a few jars later, let's find an open place, and I will perform a magic trick for you."

"What is magic?" Zhu Youneng asked.

Li Ji was stunned for a moment: "That's it, it's a trick."

The sulfur is easy to do, and there is something in the charcoal palace, and this miscanthus needs to be strenched.

Li Ji ordered the palace people to go around those earthen houses to get the whitish wall skin and soil into the water tank, remove the impurities, and then fry them in the copper furnace to get miscanthus salt.

He vaguely remembered that the best ratio of black powder was 75 nitrate, 10 sulfur, and 15 charcoal, so Li Ji made a few jars according to this ratio.

In fact, gunpowder has been used in military records during this period, in the first year of Tianyou, Yang Xingmi's army besieged Yuzhang, and the general Zheng (with the department to start the fire, burn the dragon sand gate, lead the strong men to break through the fire and enter the city first, and scorched the body).

The Spitfire mentioned here is artillery, rockets, and the like. Of course, this artillery rocket is not the kind of our later generations, the artillery is made of gunpowder into a ring, the hanging wire is ignited and thrown out with a stone thrower; Rockets tie a ball of gunpowder to an arrowhead, ignite the fuse, and shoot it with a bow.

And the power of gunpowder in this period was very scummy, and it was only used to ignite fire when fighting King De, similar to the function of fire oil.

Zhu Youneng looked at the jars in front of him: "This is it?"

Li Ji asked Youwei and Fuquan to hold a jar, and the jar was gunpowder that was configured according to the proportion. Fuquan tamped the medicine powder with a stone hammer, and sealed the mouth of the altar with mud, leaving only one lead.

Li Ji and Zhu Youneng took the four of them out of the palace and came to an open area to prepare for the ignition experiment.

The only guards accompanying him were Zhao Ergou and Zuo Dahu, who were led by Zhang Mao, and these three people were separated by Li Ji from afar, and he didn't want the gunpowder to leak out.

Li Ji said to Zhu Youneng: "Brother Zhu, this thing is very powerful, you have to keep this matter secret for me." Once the experiment is successful, we can take it for revenge. ”

"Revenge? What revenge. Zhu Youneng didn't understand.

"Liu Can, this bastard, went to King Liang to sue me and scold him, and I decided to throw a few of these things at his house when the night was dark and the wind was high."
