Li Hu was overjoyed in his heart, the other party actually invited him to join the Yipin sword guard? That's a great thing! His face immediately turned red, if he could really become a first-class official, wouldn't he have a fall for the rest of his life?

Just about to agree, he suddenly realized that something was wrong, Qian Yu said that there is no free lunch in the world, and Li Hu felt that this sentence was very right. There is no love for no reason in this world, and there is no hate for no reason, and the other party must have a purpose for saying this kind of thing at this time.

"If I opt in, what does it cost?" He asked directly.

Li Hu's upper way made Liu Shijun very satisfied: "Master Li is really fast, I want to build a cement workshop, I want to ask you for help." Rest assured, although it requires His Highness's approval to enter the Yipin Sword Guard, as long as I open my mouth, His Highness will generally not object. ”

Li Hu asked, "Lord Liu wants me to burn cement for you, right?" ”

Liu Shijun nodded: "That's right, Master Li's skills are much stronger than those of the master craftsman, as long as the cement you can burn can supply the needs of the imperial court, it is not impossible to be the commander and supervisor in the future." At that time, wouldn't it be much better for you to live in an official residence and be prosperous and wealthy than to stay in this cement workshop? ”

Li Hu's voice was still calm, but it was undoubtedly firm: "I'm sorry, Brother Qian has a great favor to the grass people, and the grass people are afraid that they will live up to Lord Liu's kindness, maybe they will not have anything to do with glory and wealth in this life!" ”

Liu Shijun looked at this middle-aged man in a daze, he knew a little bit about Li Hu's background, like this kind of person who lives at the bottom of society, has basic resistance to glory and wealth. This Li Hu is no exception, and his performance can be seen from his own proposal to invite him to join the Yipin sword guard.

But the other party refused, and refused without hesitation.

This is the first time Liu Shijun has touched a nail, and it is also the first time that a guard with a knife has been rejected. No one knows better than him how difficult the position of a first-class guard with a knife is, but the other party still refused.

All this because of one person!

He suddenly began to admire Qian Yu, although this guy has various small problems such as greed for money and cunning, he also has a very good ability to buy people's hearts!

He came this time, although he was in the name of inspecting the gunpowder workshop, but he knew that the gunpowder workshop did not need him to inspect at all, and with Jiang Feng here, how could he go?

He paid more attention to the firing of cement than to the gunpowder workshop. In Liu Shijun's view, the performance of cement is stronger than gunpowder in some aspects. Although gunpowder is powerful, it can be used to repel the enemy at most, but unlike cement, it can not only build strong cities, but also be widely used in people's livelihood.

If the gunpowder formula and the cement firing process are put together for him to choose, he will not hesitate to choose the cement firing process. If it was an ordinary person who had this secret recipe, maybe he would have robbed it earlier, but this person was Qian Yu.

Because of the relationship between saving someone, he can negotiate, induce, and plead with Qian Yu, but he can't use violence. He can see the importance of cement, as the inventor, how could Qian Yu not know?

Therefore, in his opinion, no matter what he does, Qian Yu will never hand over the cement firing method. So he had to come up with the strategy of digging into the corners of people's walls, and the result can be imagined.

Shaking his head depressedly, seeing Li Hu looking at him vigilantly, Liu Shijun sighed, since it was inviolable, he had no intention of staying, and he should go to the gunpowder workshop to have a look.

There are his own subordinates waiting for him, and it is said that Qian Yu is also there.

Wait, Qian Yu!

He remembered that from the design to the construction of this gunpowder workshop, Qian Yu seemed to be in charge. He suddenly remembered a detail, every time Jiang Feng reported to him the supervision process of the gunpowder workshop, he was excited.

Liu Shijun always thought that this was Jiang Feng's confidence in completing his requirements in the shortest time, but now he found out that he was wrong. What kind of character Jiang Feng is, no one knows better than him, and the other party has done more things that are more efficient than this, but no matter how successful he is, he is always wooden, as if the sky can't move him when the sky falls.

The only reason is that this gunpowder workshop is different!

What kind of difference should the gunpowder workshop that can make Jiang Feng excited? For the first time, Liu Shijun was full of curiosity about this gunpowder workshop.

The newly built gunpowder workshop is not close to Yunxi Village, which Qian Yu tried his best to request, the danger of explosives is too great, in case of explosion, the entire Yunxi Village will suffer.

Qian Yu chose the address of the gunpowder workshop underground. That's right, it was the cave where he and the fourth generation of Zuo were arrested by the Baiyi Sect and entered from the Jade Void. This is also what Qian Yu and Jiang Feng have discussed and decided repeatedly, gunpowder production is not only dangerous, but also must be kept secret, and there is nothing more confidential than this underground cave.

Qian Yu even gave a name to the nameless hill on the cave - Cave Mountain!

When Liu Shijun came to the entrance of the cave mountain, the feeling in his heart was only shock!

Dongshan came once when he rescued Lin Shishi. At that time, the cave was dark and damp, narrow and tortuous, and people passed back and forth, even if they held the fire fold, they could basically only rely on feeling, which is why it took three days for the soldiers and horses to search for the white-clothed cultists inside.

But now, the entrance to the cave that no one could squeeze into, can easily pass through two carriages, and this is only the entrance! Such a large project must consume a lot of manpower and material resources, right?

Seeing Liu Shijun's surprise, Jiang Feng, who had been waiting at the entrance of the cave to greet him, was very proud: "My lord, this entrance was reopened by Brother Qian through calculation, not only is the location hidden, but the distance is also the shortest. Guess how many people we shared and how many days it took to repair such an entrance? ”

Sure enough, Liu Shijun secretly said that his guess was right, Jiang Feng's very different performance was definitely because of this gunpowder workshop, and then thinking about this guy's usual appearance with a straight face and not smiling, he had an unreal feeling: "Oh, so to speak, the cost of the hole you built is not big?" ”

Jiang Feng didn't expect that he only said one sentence, and Liu Shijun roughly guessed the beginning and end of the matter, and couldn't help but stretch out his thumb in admiration: "Yes, the construction of the gunpowder workshop, the subordinates are carte blanche to the Flying Dragon Construction, and they sent a total of five people, and it was opened in one day." Four of them are still people who pick up soil. ”

"Five people, one day, how is it possible?" Liu Shijun grew his mouth in surprise, he thought that Qian Yu's efficiency would be very high, but he didn't expect it to be so high. If it were him, the best way would be to send thirty men to work day and night, so that it would be nice to do it in five days.

Jiang Feng said with a smile: "If you haven't seen the way they work, your subordinates won't believe it." But the rooster really did it with just one thing. ”

Liu Shijun was stunned: "You mean gunpowder?" ”

Jiang Feng nodded: "Yes, it's gunpowder, if I hadn't seen it with my own eyes, even if I killed my subordinates, my subordinates wouldn't have thought that gunpowder could still be used like that!"

If you control the amount of gunpowder and make a small bamboo bomb, you can loosen a large area here with just one shot, and you can't get to the foundation of the soil.

Then only four people need to transport the useless soil and stones, and then reinforce them with cement mortar. The subordinates have tried, unless they are fried with gunpowder again, they will not be able to shake it at all by manual means! ”
