King Xian breathed a sigh of relief, but the situation was far from being so optimistic as King Xian's, Xu Guo was killed by the Black Turban Army and collapsed again and again, and the southern wing of Sun Guo was completely exposed to the Black Turban Army, and there was a great attempt to bypass the Sishui River and go north from the south wing to destroy Sun Guo.

The war developed into July, the Liang army stationed west of the Lingling suddenly went south to Yongxing River Tuntian, it is also very strange to say, after receiving fifty excellent pearls from King Xian, An Taihou readily agreed to facilitate a transaction of gold and silver for pearls, and immediately moved to Yongxing River Tuntian.

And ten days ago, the uncle of Xianwang Tuoguang lobbied Antaihou Tuntian, and Antaihou never let go, and now he has gained great benefits, and his actions are immediate, which shows that people are mercenary.

In early July, the rebels who had been bombarding Guangxin for half a month stopped bombarding because Thunder Tian climbed the high platform one day and found that there were rows of unknown "buildings" at the south gate of the Xian Army.

After several days of observation, it can be found that the Xian army is hiding in the building, but no matter how the stone artillery cart and the giant crossbow arrow attack, either the accuracy is too poor to hit, or the egg is useless after hitting.

Even switched to using fireball bombs to set fires, Bailiyan poured two basins of water on the top layer of the fortifications, and even if the fireball bombs hit the fortifications, they could not penetrate and burn and spread the fire.

Thunder couldn't figure out what kind of witchcraft the Xian army used to make the building indestructible, and how it was bombarded with rocks and rain of arrows to build hundreds of "houses" on the city wall overnight. Then he built a ten-zhang high nest car and watched at the battle.

The nest cart, also known as the building cart, is used to push it near the city wall with human or animal power to keep an eye on the enemy situation in the city. There are roughly two kinds of nest cars, one is the open-air platform type, no armor protection, you need to climb on the platform, the advantage is that the platform area is wide, the disadvantage is that there is no armor protection, and it is easy to be attacked by bows and crossbows

The other is a wooden house suspended by a car, in which a person stands in a wooden house and hangs a wooden beam with a rope. This nest car is safe, but the floor area ratio is small. And the potential for retrofitting is limited. The first type of platform-mounted nest car, which can be used as a temporary vehicle with a slight modification, can be equipped with a large number of archers to launch an attack on the defenders from a high position.

The nest car created by Thunder this time is a platform nest car, which is as high as ten zhang.

Because the Black Turban Army had been bombarding the city wall 24 hours a day for the past half a month, Bailiyan had no time to rush to repair the fortifications. Of course, that doesn't mean there's no way.

After long-term observation and careful calculation, Bailiyan found that after entering the night, affected by the night, the rebels' field of vision was restricted, so they would not calibrate the target of attack as frequently as during the day, so the attack at night was a fixed target, and the range and trajectory of the bomb could be roughly calculated.

The lights on the city wall are controlled to prevent the figure from being observed by the rebels, and at night they can use the dead corner of the bomb drop point to force people to carry fortifications and building materials to the city, and then repair thirteen or thirteen tonight in the way of ants moving.

The width of the aisles of the city wall was limited, and the fortifications were all built next to the female wall on the inner side of the city wall, and the exits were opened to the east or west, and they were repaired for six days in a row, until the fortifications were arranged in groups to form a scale, and the speed and efficiency of construction were accelerated.

More than 290 temporary field fortifications were built at the head of the south gate, each of which could fit five or six people, withstanding the damage of 350 pounds of stones, and the casualties dropped from about 100 people per day to single digits.

At the same time, Jiang Gan, Chen Yunfeng, and Luo Songting also noticed the situation in the south of the city, and at first they didn't know what Bailiyan's intentions were, Wang Jiu, Hu Mo and others also ridiculed, saying that Bailiyan was a turtle with a shrunken head, and repaired the "turtle castle" to shrink inside.

Not to mention, there are bags of sand and dirt on the top and bottom of the field fortifications, and when people dodge inside, stretching their necks out, they look a little like turtle shells from a distance. But after a few days, they couldn't laugh anymore, the south of the city was the focus of the rebels, and the casualties were very heavy every day, and the casualties at the west and east gates were very small.

Since the appearance of Turtle Fort, there have been almost no casualties in the south of the city every day, on the contrary, the casualties at the east gate and the west gate are quite embarrassing. As a result, all armies and battalions vied with each other to send people to learn from them, and Turtle Fort soon sprung up like mushrooms after a rain.

"This Wei Xian, it's really a shame that he can think of it."

Jiang Qian stood in the city tower of the west gate and praised endlessly, stacking several circles of sand bags around him, and a layer of attic had been reinforced above his head, and there were two layers of sand bags on the attic.

Luo Songting was very calm, he said:

"Wei Xian is full of scheming, which is the so-called infinity."

"Compared to Mr. Luo, how much can Wei Xianzhi fall to the bottom?" Jiang Qian asked.

"Hehe, Luo can't do it."

"Mr. Luo is not exempt from being modest."

Luo Songting shook his head, and he said:

"What Wei Xian is planning is the only one in Songting's life, and there is no second person. Moreover, he is only twenty-two years old, and his future is limitless, if he reaches Luo's age, I am afraid that no one in the world is his opponent. What we say today is not a lie, but an indisputable fact. ”

"Alas......" Jiang Qian sighed and said, "It's a pity that he can't be used by us." ”

"Why did the young master say this, since there is a nepotistic marriage alliance, why worry that Wei Xian is not used by the young master and the lord."

"But his heart is longing for King Xian, how can he be equivalent to death for me."

"The young master is too worried, Wei Xian is by no means a merciless person, as long as the young master treats him well, Wei Xian will definitely protect the power of the young master."

"Maybe......" Jiang Qian didn't answer, in his opinion, it was a little unrealistic to rely on Bailiyan to keep the rights of Guangxin.

While the two were talking, Hu Mo hurriedly came:

"Report to the young master, Mr. Luo, there are signs of gathering of black turban thieves outside the West Gate, similar to attacking the city."

When the words fell, Jiang Qian and Luo Songting came to the city tower to observe the hole. The sand bags are stacked very tightly, but there are still observation holes, and when the observation holes are not in use, they are blocked with logs or sandbags, and they can be pulled out when they are used, so as not to shoot arrows into the house.

Through the observation hole, it can be seen that the rebels outside the city are indeed assembled in front of the battle, and there are box cars, ladder cars, rush cars, temporary cars, and tower cars.

The ladder truck is a four-wheeled vehicle with the lower part and the upper half of the ladder, and the four-wheeled vehicle has fixed brakes to prevent the body from skidding. Compared with the ladder that relies on people to carry on their shoulders, the role of ordinary people carrying ladders is insignificant in dealing with the three-zhang city wall like Guangxin

It is worth mentioning that the siege tower, this thing was not originally in the Central Plains, and it is not called the siege tower nowadays, but called the "tower car", which was first seen in the siege equipment of Jin Xuedi in the north, because it is narrow at the top and wide at the bottom, and the layers are distinct, so it is called the tower car, and then it is borrowed from the Central Plains to master.

Due to the extremely heavy weight of the tower carts, the Central Plains were pulled by oxen and horses to the vicinity of the city wall, and then pushed by manpower. The siege tower built by the Jin Xuedi people is far larger and wider than the siege tower in the Central Plains, and can load hundreds of people to the city at a time, like a huge troop carrier, heavy and abnormal, so it has been pulled by a war fang or a unicorn horse in armor, which is far more labor-saving than human pushing, and can rush hundreds of people on the city wall in one breath, which is a great threat.

The rebels rushed to work day and night for half a month, building more than a dozen tower cars, four appeared outside the west gate, and four also appeared outside the east gate, but six were found outside the south gate, and there were eight temporary cars, which was obviously another key care.

Bailiyan is an eye-opener this time, the previous battle of Yin Yang and the battle of Duyang, restricted by the geographical environment and the height of the city wall, whether it is the Jin army or the Xian army, have not used siege towers and vehicles, this time it is eye-opening.

"Bastard, this is meant to be played for real!"

"General Wei, let the brothers prepare." Su Hong said.

"No, let the brethren continue to hide, if this is the rebels' way to lure the snake out of the hole, will it not be in vain. Go and bring the oil and wine cans, the more the better. ”

"No."

Bailiyan does not prepare oil pots in the south of the city, the reason is very simple, if the oil pot is used well, it is inhumane to the enemy, and if it is used crookedly, it may affect his own people.

According to the mobility, the oil pan is divided into two types: base fixed type and mobile type.

The base fixed oil pot is a kind of dump copper pot with cylindrical pot ears, erected in two circular grooves of the base, and then the oil pot is heated down, and the lever is pulled after the oil boils, and the dump copper pot is poured downward, and the mobile oil pot is temporarily added.

Stationary oil pans are set up above the city gate and protruding enemy platforms, and mobile oil pans are temporarily placed along the female wall. The advantage of the stationary oil pan is that it has a large capacity, there is no need to prepare facilities in advance, and it is relatively safe, it is not easy to turn over to one's own person, and the disadvantage is that it cannot be moved.

Although the portable oil pan is convenient, the capacity is small, and the slightest carelessness in the operation process may affect you. Especially during the war, anything can happen, and it is not uncommon for someone to fall over and injure one's own person.

When you use it, boil the oil pot, and then pour a shredded meat rice on the rebels under the city, keep it a miserable street dance below, and then just need a spark, and the oil instantly burst into flames wherever it goes, so the fatality rate of the oil pot is extremely high.

But there are disadvantages and advantages, in case of being hit by a stone fired by a rebel stone artillery truck, or if you make a mistake in your busy work, or if the operator is knocked over by the muscle twitch of the arrow cluster, the last unlucky person may be your own people, and it will only be more tragic than pouring down the city.

Because the oil was all stuck in the aisles of the city wall, as soon as it burned up, it was a large area, and the fire flowed along the oil and burned wherever it burned, and there was nowhere to run.

The best way to deal with the siege tower is undoubtedly to attack with fire, but Bai Liyan found that the rebels had been covered with cooked cowhide and copper shields outside the siege tower. This means that it is difficult for ordinary rocket fire attacks to be effective, so you can only wait for the ladder carts and siege towers to get close to the city walls, and then burn their bases with fierce fire to destroy them.

The rebels are ready to move, and Bai Liyan is more and more inclined to the rebels It is not a bluff, after all, it takes time and effort to build a large instrument like a siege tower, and the rebels will never toss such a thing for the sake of bluffing.

The strongest signal before the siege is the sharp increase in the delivery rate of long-range mass killing weapons, which is called fire preparation and extended fire strike in modern military terms.

At the same time, the enemy crossbowmen marched forward in formation to within the range of the crossbows and crossbows, and launched long-range weapon coverage for the defenders above and below the city walls.

The siege soldiers worked closely with the soldiers of the equipment to launch an assault on the city walls through the passages reserved between the squares of crossbowmen.

Outside the south gate, the rebel crossbowmen were divided into two, about 12,000, in two formations, east and west, each with 6,000 people, and each formation was divided into three small formations, and the small formation was 2,000 people, and they were arrayed from east to northwest in turn.

Between the two arrays of crossbowmen are two siege towers, eight ladder trucks, four temporary vehicles, not to mention more than 4,000 people, two siege towers on each side of the two arrays of crossbowmen, eight ladder vehicles, two temporary vehicles, a total of six siege towers, twenty-four ladder vehicles, and eight temporary vehicles.

It is worth noting that in the middle of the two crossbowmen in the east and west of the rebels, there are two heavily armored carriages in the front position, the horses are all wearing heavy armor, and the carriages are also closed, and the upper end of the carriage and the surrounding sides are covered with copper plates, and the volume is larger than that of the chariot of the Xian Throne.

"General Wei, the big car in front of the rebel army is really strange, it is wearing heavy armor inside and out, this is preparing to hit the city wall." Bai He said.

"Ben will estimate that there must be calcium carbide in the car, which is used to burn our city gate."
