People in the Shanhai era have long learned to use boulders and loess to build strong cities, this behavior has begun as early as the Shennong period, and whether it is Dongyi or Baiyue, or the Central Plains, where civilization is prosperous, there are huge, incomparably strong cities standing.

However, although the city is solid, it also needs the cooperation of the level fortress.

Xunshan decided to build a huge pass, and the construction of the city in the south is obviously inappropriate, because if Sanmiao really breaks through, then it can flow in the entire southern wilderness, and the various tribes live very scattered, where to build the city, how to repair it to maximize the defense of Sanmiao's offensive artery, this is unrealistic.

Because the city and the fortress are still different, first of all, their responsible direction is not the same, one is life, the other is war, such as Ji Li Guo They can build the city on the side of the mountain, Baiyue, the Central Plains can also do this, that is because those big cities are the gathering place of a large number of tribes.

However, in the southern wilderness, the tribal residential areas are very scattered, there are some near Nanqiu, there are some in Sanshan and Siye, there are some in Jinqiu, there are some in Zhuyu Mountain, there are some in Calamus Lake, there are some in Changfeng Zhiye, and then there are Chaisang, Xunshan, Mangman, and Sheqiu where the Yuhong clan lives, if you want to count the Diyu clan, it must be extended to the edge of Lingnan.

The range is too big, and the cost of defense is too great.

It's better to build a giant pass.

"Oh, it's dangerous!"

The Summer Mountains and the Jiucang Mountains connect many mountain ranges, forming a network of tall and majestic mountains that stretch all the way to the edge of the river, blocking the extension of the northern land and protecting the southern wilderness.

Xiushui flows here, although the water flow is not turbulent, but compared with Sanyu and Chehe, the breadth of this Xiushui is even more.

Fighters work here.

The various tribes began to draw manpower, and Xunshan had already issued an order, which was the first great levy in several years.

Wizards are paid for studying guard weapons, but there is no pay for levying conscription, and each tribe must obey, which is equal in the face of the great conscription.

This is the case in the Central Plains, this is the case in Dongyi, and this is the case in Baiyue.

The same is true from the west to the foot of the Kunlun Mountains.

Even the secluded capital in the north will have a conscriptive "obedience task".

This is indeed a heavy burden imposed on the people by the "state" or "ruling class".

But then again, can some conscripts, such as the Great Wall, not be built?

If there was no Great Wall as a front-line supply line, how could the Qin army be able to defeat the Xiongnu for more than 700 miles?

However, there are a lot of people recruited by the Great Wall, although there was no story of Meng Jiangnu at that time, but there is still a saying among the people!

"Be careful not to give birth to a boy, and give birth to a girl with breasts. I can't see the corpses under the Great Wall!"

Some conscription is indeed too hasty, such as the Grand Canal, although Yang Guang is called a crime in the contemporary era, and the merit is in the future, but on the whole, it is still too much meritorious, and when the world has not been stable, such a large conscription is levied, and the resentment of Qin has risen since the first emperor, and the rebellion of Sui has been born since Yang Guang.

This is where the scourge of knocking on spectacle lies, in classical times, it was a long thing to knock on spectacle, and when it was built, there was naturally a sense of pride, but if it was rushed, it would be counterproductive.

And that's what the spectacle does.

If you want the people to be willing to knock you on the spectacle, then the spectacle must have the "meaning of the world" of its existence.

"Zai, on the northeast side of the summer mountain, there is a huge stone vein, after the foundation of the rammed earth is perfected..."

The person who spoke was the great wizard of Chaisang Mountain.

This giant level, after Yu Zai discussed it with several big bosses, it was decided to use the stone soil construction method mentioned by Yu Zai before.

Stone masonry city wall, where the stone city wall should be built in the area with more square stone, such as Taihang Mountain and Baiyue around the stone more, so there is a stone city wall there.... In particular, the coastal coastal cities were built with stone in the Ming and Qing dynasties, and it is said that in the late Song Dynasty.

The inside of the city wall is also built with stones, and then the stone strips or stones are tightly attached to the two sides of the earthen wall.

In the Shanhai tribe, it is more difficult to find a carpenter, but to find a junior masonry who chisels the mountain to open the road and crushes the boulder in the chest, it is really a big handful, and everyone on average basically knows how to open the stone with both hands.

You don't want to make a square very beautiful, but if you can't do it, just knock some edges and corners and paste them with mirage.

"A large stone mine has been found in the northeast of the summer mountain? Good thing, the mountain area is indeed full of stone veins, but in the northeast, transportation is a problem..."

"You have to climb a few hills. ”

Fei Zai faced a problem again, ox carts and small carts to transport rock salt is okay, but when it comes to transporting large stones, it is reasonable, whether it is ancient mountains and seas, ancient Babylon, ancient Egypt, basically all use the kind of primitive log carts.

Because although that thing is not good for movement and it takes a lot of effort to pull, it has a high load-bearing.

"Things that run fast are generally not big, big things generally can't run at high speeds, there is still a gap between agile heroes and tank heroes, if tanks run as fast as assassins, then what do assassins do?"

The crane is not easy to use on this hill, after all, this is the original crane, and there are still many restrictions on the use of the treadmill crane, and Danzhu is now asking a group of people to tinker with the second test model, which slows down the development of the bed crossbow.

However, I heard that there was a carpenter named Chao Shore, who was very skilled in making bed crossbows.

Is it really a stupid way to carry people on your shoulders?

"If only there were giants....."

Yu Zai sighed a little at this time, if there is a giant clan here, whether it is the Great Adult Kingdom or the Great Qin Country, or the Longbo Kingdom.... If there are giants to help, then these mountains are no longer an obstacle.

If there are giants, you can easily cut down the giant trees on the mountain and build them into strong primitive bridges.

The Great Wizard of Chaisang Mountain also said that this is the case, if there are giants to help, then this kind of thing will be much simpler, and although the Great Wizard is powerful, it is not to the point where he can move mountains and seas in a word, it is the power of the ancient gods.

There is a specialization in the art industry, you don't look at some people who don't know anything, he will also have the ability to move mountains and seas, and he is a natural civil foreman.

Yu Zai gritted his teeth and told the great wizard of Chaisang Mountain that he was going to hold a mobilization meeting.

This matter, no one can rely on it now, but only the human race itself, the vast mountains are here, can you build this place.....

No one can help them.....

The archwizard seemed to sense something, and without saying a word, he nodded.
