Dock fort this kind of thing, even if it is a primitive bunker, of course, to say that it is a fortress, you can also, but compared with the fortress of the Spring and Autumn Period and the Warring States Period, it is much smaller, the Han tomb unearthed the model of Taowu Fort, the teacher of the archaeological teammate, once participated in the excavation.

Wubao was formed in the Wang Mang period, when there was famine in the north, social turmoil, there were many homeless thieves, the rich family in order to protect themselves, so they built Wubao to lie on the corpse, in the early days of the Eastern Han Dynasty, Emperor Guangwu had ordered to destroy Wubao, but ...... This, the Eastern Han Dynasty has its own national conditions here......

The power of the family in the Eastern Han Dynasty has been growing strongly, and this is not just talking.

Even Guangwu can't demolish the illegal buildings, and the Eastern Han Dynasty Emperor behind him can't be demolished.

However, the people in the northwest often suffer from troubles, and the people automatically organize self-defense forces. After the Yellow Turban Rebellion, most of the dock forts became the private compounds of the great families.

This kind of calamity has continued until the Eastern Jin Dynasty, and after more than 200 years of Gu cultivation, the family clan has finally appeared in the old "Wang, Xie" Tang Qianyan, the king and the horse, the absurd situation of the world!

But there is no doubt that the Dock Fort built by the family is only used for defense, but even if the turtle shell is repaired well, there will always be a day when it will be broken.

Yu Zai gave Dan Zhu some suggestions, as a powerful military blocking facility, the bunker must be set up, even if it can't kill many people, but at least it can make the other party constantly harassed, and after the morale drops, Sanmiao is not a terminator robot.....

Of course, I can't guarantee that someone who will dance the god and add BUFF, and then the Sanmiao army will perform a wave of immortals on the spot, and the battle will not collapse.....

If that's the case, you'll have a chicken feather and run away.

"The material of the fortress does not necessarily have to be stone, it can be made of bricks and soil.... As for the three-way earthen wall of our tribe, with a layer of stone walls on the outside, the effect is still very good....."

That's too slow, there's not even a big clay kiln now, burn a head!

But then again, if it goes on like this, it really has to create a few wonders, what a big kiln, a big iron factory, plus 8 production capacity....

This kind of practical wonder still has to be knocked.

Danzhu spoke at this time: "Since it is a checkpoint, how can it be weaker than the defense of the city, the big cities in the Central Plains are all three layers inside and three layers outside....."

What is a seven-meter height of 2.5 meters thick and a total of 10 meters thick city walls including fortifications .... It can be used from prehistoric times all the way to the Age of Discovery.....

Is this his aunt the builder of the city?

Built so thick, you are defending against artillery salvos?

Yu Zai kept complaining in his heart, and at the same time felt that there was something wrong with these Central Plains people.

Oh, I seem to be from the Central Plains too.

"Okay, according to your standards, the level design I gave is really vulnerable....."

Danzhu's idea is that it is three or five feet thick, three or five feet high, and wide... Anyway, the road was going to be blocked, and the city wall was to be built in three rows, and he changed it according to the design plan of Yu Zai, and kept changing it, and then put forward the suggestion of "Urn City" when Yu Zai was dumbfounded.

"You build three rows, the first row is a little more protruding, and the inside is a small city, you see, it's like catching a turtle...."

Yu Zai looked at Danzhu and suddenly said, "Ah Hong, you are really a genius." ”

Danzhu was stunned for a moment: "What a genius.... Oh, you're talking about talent? I've always been talented, but I'm old...... My fellow villagers just look down on me. ”

Yu Zai: "You have mixed up with the position of Taotang envoy, and your fellow countrymen still look down on you." Aren't you from Hexi?"

Danju: "That's... My fellow countrymen are all talented..... In fact, someone like me is in my hometown..... Ahem, of course I'm special, after all, I know more, and those people are jealous of me. ”

"Okay, then again, although we are chatting here, but there is a shortage of labor, if you let those big monkeys repair, their progress may not be much faster than others, this Jindu is finished, it is estimated that there is no strength. ”

Although Danzhu said that those mountains were called to death, if these big monkeys were tired to death, it would obviously be more than worth the loss at this juncture.

There is no way, there is a shortage of people who carry big bags now, and strange beasts that have a lot of strength like these big monkeys and can help them like people seem to be really missing.

"Zai, you have great wisdom, now is the time for you to go out, don't shirk! Even if it's for my job, you have to think about it, this is a big thing. ”

Danzhu said to Yu Zai: "If this matter is not handled well, I will lose my job when I go back to the Central Plains..... When the time comes, you will be arrested, and you will not be able to make wood. ”

seems to be "threatening" Yu Zai, but in fact, Danzhu doesn't want to go back, and he will be imprisoned when he goes back, if he messes up, the emperor doesn't know how to spray him.

Yu Zai had a bitter face, Ah Hong said lightly, but he didn't recruit himself for this labor force.

You drew the design picture so big and so good, and then asked me for someone?

I'm just an ordinary wizard citizen in the southern wilderness, so you're too embarrassed for me!

"Very good.....

Yu Zai held Ah Hong's mentality that you are afraid that you are not sick, and drew something on the ground, but she didn't expect Danzhu to see this thing, and he fell in an instant, and suddenly said: "What is this!"

Yu Zai: "What a friend of mine told me, there is no physical thing yet..... It's called, a treadmill crane!"

Mangman's War Bureau.

The bed crossbow was soon imitated by the carpenters into three testing machines, but the range of each one was not ideal, and there was even an oolong problem with a shorter shooting range, which made the carpenters who were originally full of confidence have to review the knowledge taught by Danzhu again.

Didn't you expect carpentry to be such a difficult job?

But again, there is also one of them that has a better effect, shooting thirty-five steps.

"I'm the Sugishi ..... of the Nest Clan"

Chao'an made a request to the Xunshan clan, and he asked Xunshan to send someone to Yangdi Mountain to buy some "Zhuan trees".

The tree of the tree, the mountain mulberry also, the wooden is special, can make the bow and Xuanyuan, the "mulberry bow" of the Zhou Xuan King period is made of this kind of tree.

"Use the tree to make a bow arm, Yangdi Mountain has the relics of the ancient emperor, and the entire mountain is in apotheosis, and the tree there is the best in the mountains and seas. ”

The body of the crossbow is made of hard mulberry wood, the tip of the crossbow is made of sandalwood, the trigger is made of copper, and the string is made of hemp rope (see Shen Kuo's Mengxi pen talk in the Song Dynasty).....

The tree is the best choice of all wood species.

"The tree of Yangdi Mountain, the tree of Zhenling Mountain, the god bronze ..... of the Earth You"

The nest shore grabbed the crossbow string and pressed it.

"Hemp rope..... I don't know about this, but if you want to ask the Chifang clan, our clan still uses old rattan. ”

The front ones are all good materials, and the last ones can't be pulled down.
