Eight days later, Yuefeng's army was only three miles north of Huaizhou Prefecture, and Yuefeng's 160,000 army stretched five miles horizontally, and then began to garrison to create an ironclad defensive position. The front of the army was full of deep pits for a mile, and infantry and siege vehicles could pass, but it was almost impossible for the army to run horses.

The excavated earth is immediately converted into raw materials for siege vehicles. Wells were dug for water, pits were dug for fortification, and catapults were lined up in the camp. Zhang Liao led 40,000 cavalry troops to the rear and could support left and right at any time. Tuoba Gui, solemn, Yue Feng led 30,000 infantry, and 10,000 siege vehicles ranked in the left and right.

In such a position, Wei Chang attacked and harassed 80,000 troops from the left and right battalions for two days, but he did nothing except lose his troops.

Yue Feng also knew why Wei Chang dared to defend it. Originally, the left and right camps were guarded on the slopes and slopes of the east and west of Huaizhou Mansion, although the slope of the hill was flat, it was not high only thirty or forty zhang, but the fortifications were close to each other, and the two slopes were far from the city wall of the state capital. In this case, even if the East Battalion is attacked, its soldiers can defend and attack, and they can escape back to the state capital along the wall at the very least.

If the catapult goes to connect the city wall, as soon as the battalion and the North Gate soldiers come out, they can break through the catapult. And the five-zhang moat, the depth is unknown, and the twenty-zhang mountain wall is like a mountain, even if it is three days of throwing stones, it may not be broken. What's more, it is blocked, as long as they send troops from the south gate and detour to the north gate, they will be encircled.

And the east and west camps are not strictly east-west directions, more precisely, the northeast and northwest, the two east and west city gates are also very weird, in the east and west camp city wall to the north, so that the wall can protect the door, the city can protect the door, the battalion can protect the door, the distance between the three gates is not too far, especially difficult to overcome.

Yue Feng thought of Nanhuai County, which defended the south gate, and sighed that this kind of defense was obviously taking into account various circumstances, Huaizhou Mansion was narrow in the north and wide in the south, and it was difficult to defend with a gate in the south, so it was directly defended by the county. The northern part is narrower, so it is defended by three gates, two battalions, one city and one wall! No wonder Wei Chang has the confidence to make such a desperate bet! Yue Feng not only admires the sharp vision of the people who built the city at the beginning, but also the superb military mind of the gods. Yue Feng also secretly thought that if he had financial resources, his cities should also be strengthened, but in Yue Feng's heart, he still felt that the strength was far more important than the city, after all, the attack was the best defense, and no matter how handsome the city was, it would be outdated in a few decades!

In this case, the catapult can't hit the big camp, and it can hit the north gate, which is time-consuming. Yue Feng ordered to prepare enough mountain rocks to be projected for ten days, and then ordered Diao Chan to send a heaven, earth and water team to find the weaknesses of Huaizhou Mansion.

However, on the second day, Wei Chang and Yue Feng fought several times, and they were helpless against each other. It's just that the soil and stone are almost ready, after all, tens of thousands of people have dug out the pit, and the efficiency is very high! At this time, there was good news that Ma Chao broke through Nanhuai City in one day, completely annihilated the enemy army, and killed Wei Chongshan, the son of Wei Chang. He has now led an army of 100,000 to the south of Huaizhou Prefecture.

Yue Feng couldn't help but laugh when he looked at the battle report handed by Diao Chan.

It turned out that after Ma Chao Chengyue arrived in Tongzhou on the second day, because he was respected by Chengyue, Cheng Xian was also a generous person, and ordered Ma Chao Chengyue to lead 80,000 troops to the north quickly, and Cheng Xian led 30,000 troops to follow.

Ma Chaochao's rapid march arrived at Nanzhiqing County in Nanhuai County on the fourth day. After resting, he ordered people to cut down the local specialty iron tree, and quickly made more than ten attack cars. The iron tree is a special product of Huainan, long and thin, hard and heavy, the iron tree with a diameter of less than half a meter can even be 30 zhang long, weighing 1,000 catties. Ma Chao with ten wood a bundle, covered with wet cowhide, under the car splicing bearing, there are ten horses in front of the pull, and then a thousand people push a car to hit the door.

Ma Chao arrived in Nanhuai in less than half a day, the four gates attacked together, less than half an hour, the door broke the city and opened, 80,000 troops entered the city to slaughter soldiers, although more than 10,000 soldiers were lost, but the people were almost not killed or injured.

When Ma Chao waited for the dedication, but on the 8th, after Ma Chao scattered the people home, the city gate was directly burned, leaving no soldiers, and went north with all his might, and now he is stationed in the camp to block the south of Huaizhou.
