Haotian entered the Nanban Mountains, and both sides of the river were suddenly lively.

On the west bank of the river, hundreds of young people were rushing back and forth on the wharf, carrying the piles of bricks on the shore onto the boat and transporting them to the opposite bank.

On the east bank of the big river, Zhao Hao was taking two or three hundred young people to clean up the trees around a hill, preparing to build a fortress, and the big trees were constantly being knocked down by him with divine weapons, and the sound of the big trees falling down resounded throughout the entire mountain forest.

Originally, Zhao Hao was still very careful, for fear of alarming the alien beasts in the mountains of the Southern Barbarians or approaching the existence of divine beasts, after all, the lethality of alien beasts is too terrifying for ordinary people, even if it is the elite of Haotian, it is quite dangerous to face alien beasts.

The small tribes in the wild jungle often encounter the harm of foreign beasts, and Zhao Hao has also witnessed Cangwu's son Riyan being bitten by a strange beast saber-toothed tiger.

That guy is fast, ordinary people can't react at all, even a master with a strength of 1,000 catties has no power to resist.

He was really a little worried, the movement he made would be too likely to attract strange beasts nearby, and if he was negligent, his clansmen might be killed or wounded.

However, the topography of the Southern Barbarian Mountains made it impossible for him to secretly lead people to build the fortress, because there were too many trees here, and even if there was open space, there would only be a hundred or so people, which was not enough to build the fortress.

He had no choice but to start clearing the trees in a big way.

However, in order to ensure the safety of his clansmen, he is still quite vigilant, divine soldiers, he always holds them in his hands, once a strange beast attacks, he will rush up like lightning to kill it, and, every afternoon, when the sun is about to set, he will take all his clansmen back to the west bank, before the fortress is built, he will not let his clansmen risk spending the night in the mountains of the Southern Barbarians.

As for the overall plan of the fortress, he had already done it.

He planned to build the fort into three tiers, that is, to dig a platform at the top, on the side and at the bottom of the middle hill, according to the topography.

At the top of the hill was his residence and command place, and he planned to build a large courtyard according to the structure of a courtyard, surrounded by a resting place for him and his family, and in the middle was a command place similar to a large conference room.

The mountainside was the residence of the guards of each battalion, and he planned to build a row of barracks in each of the four directions of the southeast, south, and northwest according to the structure of the barracks, with ten large bungalows in each row of barracks, and a ten-man squad in each bungalow, and the four rows of barracks were just enough to accommodate all the 400 elites he had recruited.

At the bottom of the mountain are the arrow towers, the city walls and the place of exercise.

The city wall, he planned to build directly according to the mountain, that is, the slope below the ground platform was reinforced with boulders and turning heads, and a circle of walls and arrow battlements about one person high was built on top.

The arrow tower is directly behind the wall, one every hundred steps, about ten meters above the ground platform, so that the archers can not only cover the city walls on both sides, but also serve as a watchtower, no matter which direction there are strange beasts approaching, they can be found in time.

The place of practice is actually the platform of the third layer, that is to say, the platform of the third layer is actually equivalent to the wall of the city wall, and the perimeter is full of walls, arrow stacks and arrow towers, and there is a circle of platforms in the middle.

The biggest feature of this structure is that it is solid, because the wall of the outer city wall is actually the bottom of the hill, and the strange beasts run over, unless the entire hill can be knocked down, otherwise the outer city wall is impossible to collapse.

It is estimated that there is no alien beast that can collapse the mountain, at least, he has never seen it or heard of it, so there is no need to worry about the solidity of this fortress, as long as you are always on guard, it is basically impossible for the alien beast to break through.

However, the construction of this fortress is also quite difficult, and the amount of work required to dig a mountain into three layers is not ordinary.

Fortunately, at this time, the elite strength of each battalion is at least more than 1,000 catties, and they are not short of hoes and shovels, so to speak, each elite, that is more of a small excavator, and the commanders, captains and captains of each battalion have a fight with real excavators, so the progress of digging the platform is relatively fast.

Two or three hundred elites worked together, and in less than ten days, the three-story platform was basically dug up.

The next step was the construction of the walls.

The walls of this fortress are actually easier to build than the walls of Salt Stone City, because the walls of the entire city wall are the third layer of platforms, and there is no need to build them at all, and they don't even need to dig the foundation, they can directly strengthen the perimeter according to the mountain.

And the outer wall and arrow tower are not very complicated, basically the original elite who participated in the construction of the salt stone city knows how to build, plus bricks or something, they have already been ready, so, the construction speed of the city wall is quite fast, five days, the outer wall of the city wall and the arrow tower are basically formed.

At this time, Zhao Hao encountered another embarrassing problem, that is, the city gate could not be opened!

You know, the wall of the city wall is a three-story platform, that is to say, the part of the lower part of the city wall that is more than ten meters is actually a mountain, how to open the door?

When you open the door, it's full of dirt and rocks!

When the captain in charge of building the city wall came over and asked him, Zhao Hao was really embarrassed, he did ignore the problem of the city gate, because he didn't need the city gate at all, the platform more than ten meters high, he jumped on it easily, the problem, others can't.

It was not a difficult problem to solve, as long as he dug a hole in the perimeter of the city wall and built a staircase, and his small mistake did not waste much time.

After the city wall is built, all the four hundred elites can move into the newly built fortress, because with the protection of the city wall, they basically don't have to worry about the invasion of foreign beasts.

Zhao Hao immediately ordered all the 400 elites to cross the river, set up tents on the three-story platform, and make every effort to build the two-story barracks.

Four hundred elites started together, and the speed of construction was even more amazing, and in less than five days, the two-story barracks were built, and at this time, the main body of the fortress was almost completed, because the three-story courtyard was just his personal residence and command place, and it had little to do with the defense of the fortress.

However, he is still quite concerned about this courtyard, in order to improve his strength, he is estimated to have lived here in the past few years, unless Xue Man's army launches a large-scale attack, he will basically not leave the Nanban Mountains.

In other words, in the future, he and his family will settle here, and he will naturally have to refine it.

Under his command, the four hundred strong men were busy for more than ten days, and an exquisite courtyard was finally completed.

The construction of the entire fortress took more than a month, and at this time it was already late autumn, and winter was approaching.

At this time, Zhao Hao found another problem, that is, during the construction of the fortress, not a single strange beast appeared!

Could it be that the mountains of the Southern Barbarians are full of strange beasts?

He was really a little confused, if the number of strange beasts behind the Southern Barbarian Mountains was about the same as the number of strange beasts in the wild jungle to the west, wouldn't he be working in vain!
