I saw that the wooden board ten steps away was inlaid with nails, why didn't you say that the nails were full? Because a lot of the nails are inlaid sideways into the boards.

It can be seen that the power of this nail cannon is really good!

There are also traces on the ground next to it, and Leng Feng roughly estimated the range, and found that it is indeed very wide, and the enemy who is basically about ten steps will form a "middle nail".

"Yes! Although this nail cannon is not as strong as the artillery, but the range lethality is not bad, if it is to defend the city, the nail cannon is more suitable, after all, the artillery is bulky, and it is particularly difficult to adjust! ”

Zhang Zhongqing slapped the only warm barrel with a wooden stick: "That's true, the cannon is extremely hot after it is fired, and I am afraid that it will be burned red by gunpowder if I use it again, but this thing is different, it can be used five or six times in a row." And the heat dissipation is fast, and it's basically fine after half an hour. If you pour water to cool down, it will be a pillar of incense. ”

"Awesome!" Leng Feng stretched out a thumbs up to Zhang Zhongqing! To think of using gunpowder like this, his brain is really extraordinary.

Zhang Zhongqing laughed, when he asked the emperor to send someone to steal the design drawings, he just wanted Leng Feng to open his eyes, although the idea of surprise him when Leng Feng came back was shattered, but now it is the same.

"Leng Feng, take a look, can this nail cannon still be improved?"

"Yes!"

"Huh?"

Zhang Zhongqing looked at Leng Feng, his question was actually in line with the virtue of "modesty", asking and going through the motions, in his opinion, his nail cannon has been perfected, there is nothing to improve!

Leng Feng beckoned to Zhang Zhongqing, called him to the wooden board, pointed to the nail embedded in the wooden board on the side and said: "The power of the nail cannon is small, and your idea of replacing the projectile with a nail is right, but your nail, only with the sharp end forward, the lethality can be maximized, if it is on the side, it is estimated that even the fish scale armor will not be able to penetrate it." ”

Zhang Zhongqing thought about it and found that this was indeed the case, so he hurriedly asked: "Then how to improve?" ”

Leng Feng picked up a hay stalk from the ground and broke it into four sections to form a triangular pyramid: "It's enough to make the iron nails look like this, the contact place in the middle must be firm, so that they won't fall apart, such a nail sprayed out, not only can increase the probability of the nail tip hitting the person, even if it lands, it can also be used for ground thorns!" ”

Zhang Zhongqing asked for those few grass stalks, assembled them by himself, and nodded: "That's true, it's a dual-purpose thing!" ”

Such a thing, whether against infantry or cavalry, is useful.

After determining what it looks like, the rest is to hand it over to Tiesheng to be responsible for creating the finished product, and then experiment with it.

Since he came into contact with gunpowder, Zhang Zhongqing has never concluded that the coffin will be covered with the results of an experiment, and the danger of artillery is too great, and it is a safe point to accumulate nails, and he will only label it as a "finished product" after many experiments.

He didn't want his soldiers to deal with his own people without waiting to deal with the enemy.

After seeing Zhang Zhongqing's invention, Leng Feng rode home on snow, and this time he decided that no matter who robbed the road, he would not stop!

Fortunately, until he returned to the world's manor, there was no obstacle to appear.

At this time, the school at the gate of the manor happened to be out of school, and Leng Feng rode on the horse with a wide field of vision, just as he succeeded in "catching the traitor"!

Huang Zerui's kid followed Liu Shuhan again, and sent her home with a smile and a smile. Hell yes! Since this kid has been on vacation, he hasn't gone to the peasant girl, did he hit Liu Shuhan with the idea?

This is a ......... This guy has a vision!

Without disturbing the laughter of the two people, Leng Feng was attracted by the scene on the other side, the earthen house of Lao Li Tou's house was actually picked up, and the clods were being cleaned at this time.

Seeing Leng Feng looking this way, Lao Li put down the flat burden on his shoulders and bent over Leng Feng to arch his hand, looking obscene.

Leng Feng dismounted and walked over, and said to Lao Li Tou: "It's originally a crop style, why do you want to bow your hands, it's disgusting to watch." ”

Lao Li Tou said with a smile: "I only knew that you were a big official before, but now I know that you are a great benevolent person who has been praised by ten miles and eight towns, and you always have to do face work." ”

Leng Feng smiled, looked at Lao Li's family and asked, "Is this to build a new house?" ”

Lao Li nodded: "Steward Li said, this manor in the world is your Zhuangzi, our adobe house did not have to embarrass you, so we got a lot of cement, the workers asked us to find it ourselves, take advantage of the hot weather now, we can sleep in a tent outside, and every family builds a cement brick house." ”

"That's right."

Leng Feng nodded, the world manor should indeed be renovated, entering the Zhuangzi, at a glance it was full of mud houses, when Leng Feng didn't come, there were still digging caves to live, and the entire earth cave was full of pillars to prevent the soil from collapsing, and the people who watched it were sad.

Lao Li said with a smile: "This is still thanks to the blessing of the owner, if you don't work under the owner, how can you have spare money to build a house, this in the past, sons and grandsons can't eat enough, how dare you think that you can still build a house!" ”

The wasteland in Lao Li Tou's family has been converted into a breeding farm, and Lao Li Tou's family has worked for a year, not only without worrying about food and clothing, but also getting a lot of surplus money, so they are sincerely grateful to Leng Feng, the owner.

Whose farmer can have no worries about food and clothing?

The world manor!

Whose farmer can eat meat once in a while?

The world manor!

Who can save money after working for a year, and is even willing to spend money to build a house?

The world manor!

Whose children don't have to work in the fields, can go to school like the rich boy?

Only the world manor!

Lao Li felt that he was really lucky to be able to live here for the first time, the former landlord was cruel and didn't leave, and then he met General Wei Chi and got the lowest 20% rent, and now he met the Duke of Xi Guo, tsk, the good days came directly!

It's only when you live like this that you have energy! The previous decades were simply in vain!

Looking at the young owner, Lao Li Tou finally said: "Owner, after my house is built, the ......... Can I invite you to dinner? ”

When building a new house, when you go up the beams, you have to invite craftsmen and neighbors to eat, and you have to treat people on the day when it is officially built and a fire is lit.

In the past, everyone's family was in difficulty, and even those who built a new house did not dare to invite them to eat in a big way, but now that they are richer, there is still money to invite these people to a good meal.

However, he is a little unsure whether the owner will agree to the invitation, the officials are all well-dressed and well-fed, and they may not come to his house for dinner!

But what he didn't expect was that the owner actually nodded!

"Okay, tell Lao Li in advance when the time comes, I just don't have time to come."

Seduce everyone's tender monthly pass~
