Feng Yansheng's interest in fresh objects really frightened Li Yu.

Is this really a divergent mind?

But no matter what, Feng Yansheng, as a dignified Shaofu supervisor and an important minister in the court, can take the lead in rolling up his sleeves.

What about his craftsmen?

It's not going to be bad.

Li Yu also knew Feng Yansheng's personality and character, so he shook his head and smiled: "Lord Feng, you have to be careful, these cans of things may be fine if they are taken out alone, but if they are mixed together, it is easy to hurt people if one is not done well." ”

……

Li Yu was not scaring Feng Yansheng with this alarmist, on the contrary, Li Yu was afraid that Feng Yansheng would make trouble without knowing why and exhaust the materials he had worked so hard to get.

For safety reasons, Li Yusui added: "Of course, the premise is that the proportion of the ingredients of the three things must be clarified. ”

Feng Yansheng was first shocked by Li Yu's description, and then heard that Li Yu said that he still needed to match the ingredients, and the heart he mentioned fell back to its original position.

"Hou Ye startled me, so what Hou Ye needs to be tinkered with by the lower officials, some are similar to the medicinal materials that know the prescription of the pill, but I don't know how to dispense the formula of the pill to have the effect of curing diseases?"

Feng Yansheng's brain was active, and he instantly said the key point, Li Yu couldn't help but smile and said: "That's right, don't hide it from Lord Feng, Ben Hou has been making some progress today, but the effect is not ideal." ”

Feng Yansheng immediately frowned when he heard this, watched Li Yu open several clay pots one by one, and secretly thought in his heart: The things that can make Hou Ye tricky must not be simple.

And Li Yu took care of himself and introduced the clay pots: "There are a total of five clay pots here, and Lord Feng will try to save as much as possible for subsequent use." ”

Feng Yansheng nodded and asked curiously, "What kind of valuables are in the jar that can make Hou Ye cherish it so much?" ”

Li Yu shook his head and said with a smile: "It's not a valuable item, it's just that it takes some work to get these things." ”

"The three jars on the left contain something called saltpeter, the middle one is sulfur, and the one on the right is some unburned willow carbon powder."

"As for the ratio, Ben Hou groped for an afternoon, and roughly felt that the amount of saltpeter should be as much as possible; Sulfur and salixotchar can be as little as possible, and the final effect is judged by the effect of the smoke that burns after ignition. ”

The reason why Li Yu didn't directly say the actual dosage ratio of black powder was also because he was afraid that the dosage of ingredients would be too accurate, so that it would be shocking.

And more importantly, Feng Yansheng also said before that the process of cooperating with Li Yu to complete various research and construction has benefited this group of craftsmen a lot.

Li Yu is naturally happy to enjoy the beauty of adults, so that this group of Daqin craftsmen can have a process of independent exploration.

As the saying goes.

It is better to give them fish than to give them fish.

Therefore, Li Yu simply said a rough idea, and did not specify how many taels or taels of money.

When the words fell, I saw Feng Yansheng's eyes shining and rubbing his hands, and asked, "Listening to what you said, Master Hou, Xia Guan already has a rough outline in his heart." ”

Speaking of this, Feng Yan couldn't help but have some doubts on his face, and said, "However, after these things are mixed together, how should they be called?"

What does it have to do with the long iron pipe that you drew for me earlier? ”

Seeing that Feng Yansheng's brain was spinning quickly, Li Yu patted Feng Yansheng's shoulder with confidence and said, "After mixing, its shape is as black as medicine powder, and it is ignitable and combustible, so let's call it black powder." ”

"Black powder?"

Feng Yansheng immediately repeated, then nodded and said, "This name is very appropriate......

Li Yu smiled, and the things he already knew were brought out again to tell a little white like Feng Yansheng, but he was a little suspicious of Versailles.

But as long as the result is good, it doesn't hurt for Li Yu to come a few more times.

Seeing that torches had already been lit in the workshop, Li Yu knew that the sky outside must have been pitch black, so he immediately sighed and said, "Time is pressing, Ben Hou won't bother Lord Feng and his subordinates to study the recipe for black powder." ”

"I'll send you."

When he heard Feng Yansheng say that he would send off the adult, Li Yu couldn't help but refuse, and went back to the Hou Mansion.

After all, it is a waste of time and shame to let a "Great Qin model worker" who has fallen into how to develop things go out to send him off.

As Li Yu's carriage creaked down the road and returned to the Hou Mansion, the Zhangtai Palace where Ying Zheng lived was also very moving.

The first emperor Yingzheng had a habit, as long as there was no big necessary thing, Yingzheng would choose to stay in the Xianyang Palace, which was closest to the office.

Now, as soon as the early dynasty retreated, Yingzheng went straight to Zhangtai Palace unusually, and stayed for a whole day.

This made the female eunuchs of Zhangtai Palace, who were accustomed to quietness, spend the whole day trembling.

Of course, there is also Zhao Gao, an old man.

The reason, if Li Yu is here, he will be able to guess. It must be related to Hu Hai's injury mentioned by Zhang Han before.

I saw Zhao Gao quietly pestle in front of the palace gate, with a touch of sadness on his white old face, which made people feel a little sympathetic.

And Ying Zheng stood on the side with a frosty face, looking at the sparse starry sky without saying a word.

Zhao Gao only felt that at this moment, Alexander was like a man on his back, and he couldn't wait to pray that God would do well and let the eighteenth son be safe.

Speaking of Hu Hailai, Zhao Gao also felt very helpless. The weight of his playfulness made the 100,000-strong army almost defeated.

Fortunately, Zhang Han arrived in time to save Hu Hai's life.

Otherwise, even if Zhao Gao was lucky enough to survive with the help of a few good men hidden in the army, he was afraid that he would be dragged out by the First Emperor Yingzheng and beheaded for burial at this moment.

Waiting for the door to open, revealing Cai Miao's figure, Cai Miao immediately wiped the sweat from her forehead, and before she could say anything, she was grabbed by Zhao Gao's collar and asked, "Doctor Cai, is the eighteenth son okay?" ”

Zhao Gao bit the words "It's okay" very hard, Cai Miao glanced at Zhao Gao angrily, and immediately reached out and waved Zhao Gao's hand away.

He walked up to Ying Zheng tremblingly, and then said, "Your Majesty...... According to Weichen's opinion, it is better to invite the old doctor Hua. ”

Cai Miao said this, not that Cai Miao was not confident enough in his medical skills.

Instead, he felt that Hu Hai's injury was too tricky, and it had reached the point where he, a disciple of Hua Tuo, did not dare to start easily.

Therefore, Cai Miao held a wait-and-see attitude and did not make a mistake, and moved Hua Tuo out.

Ying Zheng's face suddenly darkened when he heard this, and he was actually reluctant to let outsiders know about it.

But seeing that the medical officer Cai Miao couldn't do anything, Ying Zheng had no choice but to ask again: "Is Hu Hai really serious enough to need to invite Hua Tuo?" ”

You can't say it's because you don't dare to do it......

Then the number one doctor in the palace is too cheap.

Therefore, Cai Miao had no choice but to bite the bullet and say: "The eighteenth prince was injured in the lower plate, and the lower plate was quite subtle, although Wei Chen knew how to deal with the injury, but ...... I implore Your Majesty to make a merciful decision and quickly invite a Chinese divine doctor, and the root of the eighteenth son's illness cannot be delayed any longer. ”
