Tiekun talked freely in the account, but Mutu, who was the head of the big account, was very depressed. As the 34th son of Khan king muhao, he was also the commander appointed by Khan king muhao and Zuo Sheng Wang muchao to preside over the construction of cities and underground palace excavation at the West foot of Yao mountain. In theory, Mongolian war should obey his scheduling.


    However, the demon barbarian tribes are in the transitional stage of development from tribe to Khanate on the vast sea grassland. Even the history of the rise of Blackstone Khanate in the hands of Khan king muhao is less than a century. The theory of lineage has not been deeply rooted in the hearts of the people, and the constraints on the tribes are still quite loose. Leaders like Mutu have suffered losses and dragged down the tribes, There is no prestige.


    Even in the big account, Mutu''s suggestions will not be valued by other barbarians.


    Although Mueller was the actual commander of the battles in Tongkou City, and many decisions were made by Mueller, Mueller was not in Yaoshan at this time. Many tribal leaders spread their grievances about the heavy casualties of their children on Mutu''s head.


    Even when Tuoba Yan and Zuo Jiu led the troops to attack, Mutu was too cautious and only let the Mongolian war lead 20000 soldiers to attack. As a result, the army couldn''t bite Tuoba Yan''s hard bone after arriving at Silverstone beach, and had to return from Silverstone beach to the West foot of Yao. Some people attributed the responsibility to Mutu and said a lot of strange things behind his back.


    In comparison, although tiekun had a humiliating history of being kidnapped as a slave by the Terrans, the first World War in Yinshitan was so beautiful. Moreover, when he withdrew from Tongkou City, the soldiers and horses in Tieya Department lost very little. At this time, although some people still satirized tiekun with old stories, his words could make many pretty generals listen to him and nod their heads, I think tiekun''s strategy of leading Tieya to build a city at the south foot to contain the enemy is really very good.


    Mutu was depressed, but at the same time, he felt a little strange.


    Tiekun''s strategy is good, but if the people and soldiers of Tieya department are transferred to the south foot to build a city, it is an extremely risky behavior for Tieya department. Even if they can successfully contain the enemy, Tieya department will suffer heavy losses.


    Another possibility is that tie Kun felt that the West foot of Yao mountain was more dangerous, so he had to move the people of Tieya from the West foot to the south foot, so that tie Kun and the soldiers of Tieya could be separated from his vision of fighting with Mongolia.


    If so, tie Kun''s mind will be a little bad!


    Mutu stared suspiciously at tie Kun and asked, "how many of the Ju people in Tieya moved to the south foot to build a city, and how many enemies can they contain?"


    His prestige was damaged at this time, and tie Kun had really won a beautiful victory at Silverstone beach before. Mutu could not directly question tie Kun''s different intentions.


    "I was kidnapped as a slave by the Terran. Although it was an indelible humiliation in my life, this experience was not completely unhelpful," tie Kun explained in a deep voice, knowing that Mutu or Mongolian war would have such doubts, "I have learned the methods of building a city, forging armour and war equipment. I have returned to the iron cliff department in recent years and taught these methods to my people. If I can lead the iron cliff tribe to move to the south foot, my family will have six or seven thousand War soldiers available. More importantly, the people of the iron cliff department can build a stronger stronghold in the deep mountains and dangerous valleys at a faster speed, so that the enemy has to divide their troops in the south foot, but There''s no way to attack! -- of course, I also asked Prince Mu and general Zuo du to allow me to transfer forty or fifty thousand bitter slaves from here. Otherwise, with our forty or fifty thousand people in Tieya department, we can''t contain too many enemy troops, and it''s difficult for Prince Mu and general Zuo to share too many worries. "


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


    "Let''s see what you can do at the south foot."


    The Mongolian war was still worried that the fangtieya tribe would move to the south foot to build a city, which might form a department of its own. At that time, the control of the MengWu tribe over the Tieya tribe would be seriously weakened. Finally, the clan leader of the Tieya tribe, who was also the brother of tiekun, led thousands of people who were good at building a city to stay in the West foot to help build a city barrier and fortress here, and disagreed with all the Tieya tribes moving to the south foot.


    In fact, the generals of Tieya department, even the patriarch tiedu, were full of confidence and high hopes for tiekun at this time, but from a safer point of view, they did not want to put all their eggs in one basket. The final result of the negotiation was that tiekun led 30000 ethnic people and 30000 ethnic slave workers to the south.


    The meeting did not end until the lights were on. Although Mongolian war was worried, a banquet was held in honor of the tribal leaders.


    However, the overall situation is unfavorable. Everyone in the field is depressed. Occasionally, a few pretty generals want to drink freely. They also realize that the atmosphere in the big tent is wrong and leave in a hurry after dinner.


    Tiekun and his brother tiedu returned to the habitat of Tieya tribe in the spring dew and moonlight.


    Looking at the scattered campfires, listening to the familiar local voice from the tent, looking at the young people who have just grown up in the family, still practicing martial arts hard at night, tie Kun swept the haze from his chest.


    For the sake of these people who gave birth to themselves, even if there were more difficulties ahead, it was worth fighting for. After a few words with brother tie, he went to his tent.


    Across the tent, tie Kun could see Chen Hai''s bent figure and let the lights in the big tent project on the animal skin tent.


    Tie Kun intends to take a heavy step, but Chen Hai in the big tent seems to be unaware and continues to focus on writing and painting.


    Tie Kun''s eyebrows were slightly frozen. He didn''t have no doubt about the hunchback old man. He even suspected that he was being led by the hunchback old man. Even though he had the ambition to break away from the control of the MengWu department and lead the iron cliff department across the vast sea and grassland, he wouldn''t have been so early and so fast if it hadn''t been for the seemingly unintentional persuasion and inducement of the hunchback old man for days, It was so obvious when there was no climate at the iron cliff that Mongolian war and Mutu were aware of it.


    However, tie Kun couldn''t refuse the hunchback old man''s suggestion. Thinking about it, he was also depressed. He lifted the curtain and walked into the big tent.


    Chen Hai stopped the pen in his hand, looked up and nodded slightly. He said hello, or then buried his head in what he was doing.


    Tiekun stood in front of Chen Hai. After a long time, he didn''t see the beginning and didn''t speak. He asked curiously, "Duke Cao doesn''t want to ask. Just now, Zuo Du will convene the generals to discuss the matter?"


    "There''s nothing to ask. In this case, can mengzhan and Mutu think of a better plan than iron master? Except for iron cliff department, few other tribes are good at building and defending the city..." Chen Hai said.


    Tie Kun was speechless for a while. He looked over and saw that Chen Hai had drawn dense lines on the animal skin. He said curiously, "what is this?"


    "This is the construction plan of the evil ape city. In the past hundred years, the departments of the vast sea have also built many cities on the grassland, but they are too crude, and the project of Quarrying and building cities is huge, which is difficult to build in a short time. The enemy is about to attack on a large scale. If the iron cliff department wants to successfully build a city at the southern end of the ape Leaping Gorge and contain the enemy, it must find another way," Chen Hai said, In a hurry, he perfected the design drawing. Langhao pen turned lightly on his fingers and said with a smile, "it''s done!"


    Tie Kun took the animal skin. It looks like it.


    The whole Yaoshan mountain is located on the South Bank of the Han sea. It stretches more than 500 miles from east to west. It is not a magnificent mountain in Yanzhou, but it is quite rare on the grassland on the South Bank of the Chao sea.


    The underground palace is located at the West foot of Yaoshan mountain. The terrain at the West foot is relatively gentle. In ancient times, the access to the underground palace was at the West foot. There are still some traces of axe carved stone walls in the valley of Bailu gorge.


    Although you can walk out of Yaoshan mountain and enter the vast grassland more than a hundred miles to the south from the underground palace, the terrain to the south is much more steep. There are strange peaks and deep valleys along the road. Several connected canyons go deep into kilometers. The local tribes call it ape jumping gorge, which means that evil apes can come and go freely in these canyons.


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


    Tiekun didn''t see the details of the structure of the city, but he was shocked when he saw the city building site selected by Chen Hai and said: "There is a dangerous place in ape Leaping Gorge, which is only 300 steps wide. It is also a necessary place to enter Bailu gorge in the north. It is easy to defend and difficult to attack if you build a city there. Cao Gong did not choose to build a wall there to resist the enemy, but extended more than ten miles from the outside of ape Leaping Gorge. Why did he choose to build a city at the widest part of ape Leaping Gorge, which is also the place most vulnerable to three-sided attack by the enemy? Cao Do you know how much manpower and time it takes to build a wall four or five miles wide, 15 meters high and 20 meters thick? "


    "The tieyabu people are less than 50000. Even if they can get 50000 slaves, they may succeed in mining stones and building cities here in three years according to the traditional method," Chen Hai said.


    "I can only lead 30000 people and 30000 slave workers to the south foot this time. Won''t it take five years to build this city? I don''t know what clever plan Duke Cao has to delay the enemy until five years later?" tie Kun asked calmly.


    "Build a city according to the usual method. Even if you build a city in the narrowest place, iron master can''t build the city before the enemy comes. Besides, iron master really wants to keep Tiger Leaping Gorge watertight so that the enemy can''t see any chance. The enemy can seal the iron cliff in tiger Leaping Gorge and ignore it. Iron master chooses to build a city in the narrowest place. It''s easy to defend, but he is ignored by the enemy It''s naturally easy to block the inside. At that time, it won''t contain many enemy troops, let alone build miracles. "


    Chen Hai said slowly,


    "Before I came here, I made a special trip to Tiger Leaping Gorge. At the place where I chose to build the city, there was a kind of earth slurry which was mined locally, calcined, ground into powder and mixed with clay. It was used to tamp the city wall. It was ten times faster than quarrying the city. It only took three or five months to build a city wall five or six miles wide. Although such a city wall was weaker than stone city Some, but with iron master''s strength, I can''t cut the city wall with a halberd. I have written down the method of building the city. Iron master can send someone to test it first, and then decide whether to build the city there... "


    "Is there such a way to build a city?" tiekun asked suspiciously, but he didn''t immediately go to see the animal skin scroll. Instead, he fixed his eyes on Chen Hai and asked, "Cao Gong, now you can tell me why you have tried so hard to help me?"
