There was no loophole from Tie Kun's words. Mutu knew that he would continue to question for no reason, so he had to say in a muffled voice:

"Then let's see what you can do in the southern foothills."

Meng Zhan was still worried that the Tieya tribe would move to the southern foot of the city to build a city, which might be a natural formation. At that time, the Mengwu tribe's control over the Tieya tribe would inevitably be severely weakened. In the end, he insisted that the clan leader of the Tieya tribe and Tie Kun were also the brother of Tie Kun, leading thousands of tribe members who were good at building cities to stay in the western foot of the mountain to assist here in building a city and defending village. He did not agree that all the Tieya tribe members would move to the southern foot of the mountain.

In fact, even the generals of the Tieya tribe, even the clan leader Tiedu, were full of confidence in Tie Kun and had high hopes. However, from a more safe perspective, they did not want to put all the eggs in a basket. The final result of the negotiation was that Tie Kun led 30,000 tribesmen and 30,000 human slave workers to the south.

The meeting was not over until the lights were on. Although Meng Zhan was worried, he still held a banquet to entertain the leaders of various tribes.

However, the overall situation was not good, and everyone in the field was depressed. Occasionally, a few generals wanted to drink a lot of slutty. They also realized that the atmosphere in the big tent was wrong, so they hurriedly said goodbye after eating.

************************************

Tie Kun, his brother Tie Du and others returned to the habitat of the Tieya tribe in the spring dew and moonlight.

Looking at the starry campfire, listening to the familiar local accent from the tent, and watching the young man who had just grown up in the clan, who was still practicing martial arts hard at night, Tie Kun swept the haze in his chest.

For these tribe members who gave birth to themselves, no matter how many difficulties and dangers there are ahead, they are worth fighting for. After saying a few words to their brother Tiedu, they walked towards their tent.

Through the tent, Tie Kun could see Chen Hai's hunched figure, allowing the lights in the big tent to be projected on the animal skin tent.

Tie Kun deliberately made his pace heavy, but Chen Hai in the big tent seemed to be unaware of anything and continued to focus on writing and drawing something.

Tie Kun's brows were slightly froze. He had no doubts about this hunchback old man, and even suspected that he was being held back by this hunchback old man, and was walking away. Even though he had the ambition to escape from the control of the Mengwu tribe and lead the Tieya tribe to traverse the vast sea grasslands. But if this hunchback old man had not been persuaded and induced for several days, he would not have been so early. So quickly, when the Tieya tribe could not have become a climate, it would have been so obvious that Meng Zhan and Mutu both noticed it.

However, Tie Kun could not refuse the suggestion of this hunchbacked old man. He was depressed when he thought about it, so he lifted the curtain and walked into the big tent.

Chen Hai stopped the pen in his hand, raised his head and nodded slightly, as if he had said hello, or continued to do what he had at hand.

Tie Kun stood in front of Chen Hai, but after a while he didn't see the beginning and asked curiously: "Don't Cao don't want to ask, is the situation where Zuodu summoned the generals to discuss matters just now?"

"What's there to ask? In this case, in Meng Zhan, can Mutu think of a better plan than Tie Ye? Apart from the Tieya tribe, there are not many other tribes who are good at building cities and defending cities..." Chen Hai said.

Tie Kun was speechless and looked over. Seeing that Chen Hai had already drawn dense lines on the animal skin, he said curiously: "What is this?"

"This is the construction design drawing of the Demon Ape City. The Hanhai tribes have built many cities on the grassland in the past hundred years, but they are too crude, and the project of quarry building is huge, which is difficult to build in a short period of time. The enemy is about to attack on a large scale. If the Tieya tribe wants to successfully build a city at the southern end of Yuanzhexia and restrain the enemy, they must have a different path." Chen Hai said, and quickly perfected the design drawing. The wolf brush turned it lightly on his fingers, and laughed, "It's done!"

Tie Kun took the picture of the beast skin and looked like it.

The entire Yao Mountain is located on the south bank of the vast sea, with a length of more than 500 miles east-west. It is not a magnificent mountain in Yanzhou, but it is quite rare on the grasslands on the southern bank of the Chaohai Sea, which is full of thousands of miles.

The underground palace is located at the western foot of Yao Mountain. The terrain on the western foot of the mountain is relatively flat. In ancient times, the passage to and from the underground palace was at the western foot of the mountain. There are still traces of axe-carved stone walls left in the valley of Bailu Gorge.

Although you can walk out of Yaoshan and enter the vast grasslands from the underground palace for more than a hundred miles south, the terrain south is much more steep. There are strange peaks, deep valleys, and several canyons connected together, all of which go thousands of meters deep. The local tribes call it the Ape Jue Gore, which means that demon apes can come and go freely in these canyons.

The animal skin map identifies the location of the city building selected by Chen Hai.

Tie Kun did not see the structural details of the city, but was shocked when he saw the location of the city building that Chen Hai selected and said, "There is a dangerous place in Yuantiao Gorge, which is only 300 steps wide, and it is also a must-pass place to enter Bailu Gorge north. Building a city only requires building a city wall of 300 steps long, making it easy to defend and difficult to attack. Cao Gong did not choose to build a wall there to resist the enemy, but extended dozens of miles from the outside of Yuantiao Gorge. He chose to build a city at the widest place of Yuantiao Gorge, which is also the most susceptible to attack on the enemy from three sides. Why? Don't Cao Gong know that how much manpower is needed to build a city wall that is four or five miles wide, fifteen meters high and twenty meters thick at the base of the city wall. How much manpower is needed and how long will it take to build it?"

"The Tieya tribe has less than 50,000 people, and even if they can still get 50,000 slaves, they can mine stones here to build a city in three years," Chen Hai said.

"I can only lead 30,000 tribes and 30,000 slave workers to the southern foot. Wouldn't it take five years to build this city? I don't know what kind of tricks Cao Gong has to delay the enemy until five years later and then attack again?" Tie Kun asked calmly.

"Build a city with the usual method. Even if you build a city in the narrowest place, Tie Ye cannot build a city before the enemy comes. Besides, Tie Ye really wants to guard the Tie Leaping Gorge so that the enemy will not see any chance. The enemy can seal the Tie Ya tribe in the Tie Leaping Gorge and ignore it. It is easy for Tie Ye to choose to build a city in the narrowest place, but it is naturally easy to be blocked by the enemy. At that time, it will not be able to restrain many enemy troops, let alone make more wonderful achievements."

Chen Hai said slowly,

"Before I came here, I went to Tiger Leaping Gorge for a walk. At the place where I chose to build a city, there was a kind of stone mined on the spot, grinding it into powder, and mixing it with clay. It was used to build a city wall. It was ten times faster than building a city wall with stones. It only took three or five months to build a city wall five or six miles wide. Although such a city wall is weaker than Shitou City, with the strength of Tie Ye, I couldn't do it if I wanted to break the city wall with one halberd. I have written down the method of building a city. Tie Ye can send someone to experiment first and then decide whether to build a city there..."
