During the Three Kingdoms period, the city was mostly divided into two layers, the inner city was mainly a military and political institution, which was the core of the city's rule; The outer city has two main functions, one is the main business circle of the region, and the other is military defense and protection of core institutions.

Therefore, the outer city usually has a high and thick wall, and there are usually wide and deep moats dug outside the city wall, which is what we usually call the pool of the city.

Nowadays, many cities have moats, and most of them are ancient pools that guarded the outer city. Moats are generally very wide, and it is said that the largest moat in Chinese history is the Xiangyang Moat, the widest of which once reached 250 meters, and its defensive role in the era of cold weapons can be imagined.

Moats are generally filled with water, usually using river water, and if there is no condition, they will try their best to dig groundwater and fill it. There are some elaborate generals, and they will also set up wooden thorns, pits and other facilities at the bottom of the moat to strengthen the defense.

Changsha is located in the Yangtze River Basin, the rivers are widely distributed, the Xiangjiang River, the Laodao River, the Liuyang River and other rivers pass through, and the moat is naturally full of water in all seasons. Therefore, the defense force of the outer city of Changsha is quite strong.

However, there is a good and a bad thing. It is precisely because of the extremely strong defensive capability of the outer city of Changsha that the defenders of the past dynasties basically disagreed with the fortifications of the inner city.

This led to the extremely weak defense of the inner city of Changsha, the city walls were very low, and even the inner city gate was pure wood, and the thickness was average.

It is estimated that Cai Mao was also aware of the weakness of the defense of the inner city, so he sent the elite troops out to intercept Gao Yun, but he didn't expect to be defeated by the man who used the fishbone gun, and even the generals were dead.

Gao Yun saw that this man was going to break the city gate alone, and he was also very moved. Although he has some identity, he has no idea from the man in front of him after all. People can be so desperate to take care of themselves, and this affection is not unimportant.

Thinking like this, Gao Yun hurriedly stopped the man and said with a smile: "The strong man is slow, I have never known the strong man in my life, and now in order to regain my brother's soul, the strong man is working so hard, which makes Gao Yun very impressed." Dare to ask the strong man to respect, and the next day he will repay him."

The man grinned, bowed to Gao Yun, and replied: "In Xia Ganning, the small character Xingba, the people of Ba County." In the early years, he entangled the dead and did some dishonorable deeds in the river, and he was deeply guilty. Later, he was enlightened by a master, regretted not being at the beginning, and decided to change his past. I have long heard that General Huwei is generous, benevolent, wise and brave, although he wants to serve, but he has no way to advance. Now that I am fortunate to meet the general leading the troops south, I don't want to miss it, so I gathered in Changsha City and had to serve the general, which is the luck of three lives, and I dare to forget about life and death? ”

When Gan Ning said this, he suddenly lifted his clothes, rolled the saddle and dismounted, bowed down in front of Gao Yun, and kowtowed: "Pray that the general will be included, and we are willing to tie the grass title ring to repay the general."

When Gao Yun heard that it was Gan Ning, his heart was immediately relieved, no wonder he had such a ability.

Gan Xingba wanted to join his command, and Gao Yun was so happy that he almost danced.

In addition to being a rare general who is both civil and military, it may also be because of the special life experience of Gan Ning's prodigal son, Gao Yun attaches more importance to him.

Gan Ning's life can be described as full of legends, when he was a teenager, he was uninhibited, entangled prisoners and dead soldiers, plundered both floods and droughts, and caused a lot of murder. After the age of twenty, for some reason, Gan Ning suddenly had a big enlightenment, and began to study hard in military books and war strategies, and the sons of a hundred schools, and changed his past wrongs and stepped into the right path.

In the subsequent career as a general, Gan Ning was also the leader, killing Ling Cao, breaking Huang Zu, attacking Cao Ren, rejecting Guan Yu, capturing Zhu Guang, and attacking Cao Ying with hundreds of horses, with great achievements in his life.

Gao Yun saw Gan Ning kneeling in front of the horse, hurriedly snowed the unicorn, took a step forward from the mountain, hugged Gan Ning with both hands, and said with a smile: "Who can have such a means, it turns out that it is Gan Xingba, a heroic man on the river." Hahahaha! It is my life's wish to be able to get the help of Xingba! Why do you need such a big gift, please hurry up".

Gan Ning stood up, overjoyed, bowed his hand to Gao Yun, and changed his words: "Lord, how dare you work in such a small inner city." Please take a look at the array for your subordinates here to see if your subordinates can be used! ”

Gao Yun laughed, "Good! Just about to see the means of Xingba! ”

Gan Ning bowed to the leader's order, turned over on his horse, put two fingers in his mouth, and whistled loudly. In an instant, nearly a hundred big men gathered from all around, all of them carrying swords and shields, and their movements were extremely fast.

Gan Ning urged the horse's hooves, took the snowflake iron fishbone spear forward, and shouted: "General Huwei has an order, take down the inner city and recapture Sun Wentai's spiritual body!" Brothers, kill with me! ”

When the hundred strong men heard what Gan Ning said, they seemed to be greatly encouraged, and they moved one by one, shouted and marched, and followed Gan Ning to the inner city of Changsha.

Cai Mao had already seen his team of sword players being killed at the head of the inner city wall, and at this time he had gathered crossbow archers to guard the wall. Seeing that Gan Ning led a team of warriors to attack the city wall, he hurriedly ordered, "Release the arrows!" Shoot the arrows! ”

The archers on the city responded to the sound, and thousands of people flew down and attacked Gan Ning and the others.

Gao Yun couldn't help but secretly worry, although Gan Ning's skills were not a problem, but Gao Yun didn't know the combat strength of these strong men. This flight is from top to bottom, it is extremely difficult to dodge, even if it is the soldiers and horses of the Huwei Army, I am afraid that only the soldiers of the ghost snatching camp can do it, and it must rely on the defense of wooden armor.

These strong men had no armor and wore only tight-fitting cloth clothes. Since he promised Gan Ning to include his vote, then these people under him have all become soldiers of the Huwei Army, how can Gao Yun not worry.

Just as he was about to order the ghost to grab the camp for cover, a scene that surprised Gao Yun appeared. The nearly 100 strong men were trapped in the chaotic arrow array, and they each reached out to grab the flying arrows, and every time they caught, they were killed until the gate of the inner city, and no one was injured.

This made Gao Yun really surprised, to say that Gan Ning's martial arts are outstanding, it is all expected. But all of his men were so strong that they grabbed arrows with their bare hands, which would be too sensational. What's more, those arrows are still flying from top to bottom at close range.

Gan Ning killed in front of the city gate, shook the snowflake fish bone gun in his hand, and lit eight shots in succession on the city gate, shouting: "Break!" ”

Eight strong men behind him rushed forward in response, shouted a trumpet, and the eight men slammed into the city gate with their shoulders in unison. Just listen to "Bang! With a bang, the city gate was slammed into pieces.

Gan Ning took the lead and entered the inner city. The nearly 100 warriors behind him also took off their swords and shields one by one and shouted to kill. Those blades turned out to be the same as Gan Ning's spear blades, all of them were a row of bright fishbone barbs. Nearly 100 fishbones were waved at the same time, which was terrifying.

Cai Mao and Zhang Yun were in the city, watching Gan Ning and his party break into the city, they were frightened, and they went down to the city in a panic, and they got on their horses and ran north
