Zhao Yun and the others were fighting and talking, which added a little anger to the Hou Mansion.

As soon as Li Yu entered the back garden, it was half a day, and Zhang Deli, who had lost money, returned from the kitchen and needed to report to Li Yuyu, which made Li Yu realize that it was too late.

And the puddles of seared black marks on the ground seemed to tell others what Li Yu had been busy with this afternoon.

That's right, Li Yu was setting out to develop gunpowder, which was still the most traditional black powder.

Saltpeter, charcoal, and sulfur, these are the three things that Li Yu has been tinkering with all afternoon.

It's a pity that the ratio of black powder has always been a little different from the effect Li Yu imagined, and these discrepancies still make Li Yu unable to find the root of the problem at all.

Li Yu got up and sighed and said, "It seems that the only way to do this is to let Lao Feng start to explore, as for how long it will take to make the black powder reach the best ratio, it depends on the level of the Great Qin craftsmen." ”

Thinking of this, Li Yufang raised his eyes to look at Zhang Deli and the cook beside Zhang Deli.

Seeing this, Zhang Deli hurriedly introduced: "Master Hou, this is our chef Zhao ...... of Shiweiju"

"Zhao Si."

……

Zhang Deli and Liu Neng looked at Li Yu in surprise, the former was surprised, and the latter was excited.

Zhang Deli didn't expect that Li Yu, who had a lot of opportunities, would remember a cook and call out his name in person.

The chef Zhao Si didn't expect that he would be a small person, and he would be a big man like Xianjun Hou and remember his name.

What the two didn't know was that Li Yu hired a chef with a lot of money, and when he saw the name "Zhao Si" on the list, he almost burst into laughter.

With such a deeply rooted name, Li Yu naturally remembers it clearly.

"You don't have to be too nervous, you are on an errand for Ben Hou, as long as you do your best, Ben Hou will naturally not treat you badly."

As soon as Li Yu said this, the cook Zhao Si felt cordial when he heard it, and the nervousness in his heart also dissipated a lot.

Then he stammered a little and said: "Big, don't worry, Steward Zhang has already explained to the little one when he came, and the little one will not let the adult down." ”

Li Yu smiled, and then waved his hand to let Zhang Deli watch and do it himself, while he himself had more important things to do.

Regardless of the approaching night, Li Yu hurriedly packed up a few cans of materials for making gunpowder, and asked Zhao Yun to drive the carriage straight to the outskirts of Xianyang City.

……

The suburbs of Xianyang, Foundry Division.

There was still a familiar, pungent smell floating in the air.

Li Yu entered the workshop with his mouth and nose slightly covered, and as expected, Feng Yansheng, the "Great Qin Model Worker", was really staying in the Foundry Division.

Seeing that someone had reported it, Feng Yansheng got up and greeted him, and said with a smile: "Master Hou, why are you here?" ”

Li Yu looked at a few objects on the table, and joked with a smile: "Old Feng, you have to go to the market every day, don't you care about your mother-in-law at home?" ”

When Feng Yansheng heard this, he looked around at the moment, and saw that the other craftsmen and subordinate officials were busy, so he whispered a little embarrassedly: "Master Hou doesn't know, the wife of the family is really strong, and the lower officials also take this opportunity to avoid it." ”

Feng Yansheng's words were only spoken, and Li Yu was allowed to think too much.

Li Yu looked at Feng Yansheng with some sympathy and said, "Anyway, Ben Hou still doesn't know how many people in your family are Lord Feng. ”

Hearing this, Feng Yansheng stretched out three fingers and gestured, and said, "Xia Guan doesn't like groups of wives and concubines, so he only has three children. ”

Li Yu grinned and teased me: "I don't think Lord Feng doesn't like it." ”

Feng Yansheng's old face turned red, and he couldn't help but be surprised in his heart: Junhou, a person who has not yet married a family, how can he gossip about other people's family affairs so much?

Then he coughed a few times in embarrassment, and changed the topic: "Xia Guan, I haven't seen Lord Hou here for a long time, I remember the last time I came, it was when I came to build the Qin Blade Repeater." ”

When Li Yu heard this, he couldn't help but sigh that time flies like a fly, and time is like an arrow, so he sighed: "Yes, this blink of an eye has passed for a long time, and these craftsmen in your company are still so busy." ”

"The Foundry Division can have today's weather, thanks to Master Hou."

Hasn't the weather always been like this?

Li Yu was puzzled, so he asked, "Why do you say this?" ”

Feng Yansheng glanced at the craftsmen who were busy with the enemy and said with a smile: "These craftsmen in the Foundry Division have long been accustomed to the current process of manufacturing standard equipment and coins. It is precisely this inherent process that causes many craftsmen to lose their own ideas.

And such a situation can also be said to be the bottleneck period of craftsmen. It is precisely because you arrived with those technologies and even drawings that they have never thought of and seen, that they have broken through the inherent ideas and broken through the bottleneck. ”

"Maybe it seems that the lower officials are patting your ass, but it is indeed because of Master Hou that the Foundry Division has undergone new changes."

Feng Yansheng's heartfelt remarks made Li Yu feel a little accomplished in his heart, and an indescribable emotion filled Li Yu's heart.

So much so that Li Yu sighed in his heart: Bringing tangible benefits to others, so that they can deeply feel these different things I have brought, this is the so-called sense of achievement?

But in any case, modesty makes people kind, Li Yu grinned and said: "Maybe the so-called process production imprisons their thinking divergence, and what I do is just help them open the shackles and let them imagine and develop." ”

"Thinking differently? What does this mean? Li Yuyi accidentally said a word in the future, and Feng Yansheng asked with a puzzled face.

Li Yu immediately snorted and said, "It's not interesting, it's just imagination." ”

Feng Yansheng nodded, looked at the several clay pots on the table, and asked, "Master Hou, what is in the jar?" ”

Li Yu's eyes narrowed slightly, and then he smiled a little mysteriously: "Do you remember the forged steel pipe that you made some time ago?" ”

Feng Yansheng's eyes lit up, and then he said, "Could it be that there is a connection between the two?" ”

Li Yu immediately patted Feng Yansheng on the shoulder and said, "I'm not afraid to tell you, Old Feng, if this thing is successfully developed and successfully launched, its achievements are far from being comparable to the crossbow and Qin blade, and it is even on top of the three-piece set of imperial horses." ”

As soon as Li Yu's voice fell, Feng Yansheng's expression changed suddenly, and his head buzzed and he was stunned.

Even crossbows, Qin blades, those are all Feng Yansheng's proud works, far from being comparable to them?

Its achievements are even in stirrups, horseshoes, saddles......

Grandma's legs, what the Hou Ye said had to be a thing, so that these miracle objects would be incomparable, or even overshadowed.

Feng Yansheng was so shocked that he couldn't find the words to describe it, so he could only look at the few clay pots on the table in a daze.

And as Feng Yansheng's mind continued to diverge, Li Yu could even hear his gradually worsening breathing.

"Master Hou...... Don't sell it anymore, let's conquer it!"
