In the early morning, in the northwest of Yanling City, a large group of soldiers were building a floating bridge at night. Because it was not too far from the city, in order to avoid alarming the defenders, the floating bridge they built was a bit special, using a sheepskin raft.

Sheepskin sacks need to blow air inside with their mouths, blow the sheepskin sacks up, then tug the mouth, tie them with other skins, and some bamboo, and a sheepskin raft will be made.

Blowing is a job of hard work. In order to hurry up, the soldiers use their "foot stitches" to encourage the sheepskin.

The so-called "foot row" is a reduced version of the "water row" of the iron smelting furnace blower in the iron smelting furnace. This kind of air blowing device is used to step on it with your feet, which saves effort and boosts the air at the same time. The sheepskin bags that have been prepared will soon become round and bulging.

Someone looked at the sheepskins and couldn't help but feel a little heartbroken: How many sheep you have to kill and how much effort it takes to peel it!

The production of sheepskin sacks is very particular. In order to ensure the integrity of the skin, you must first use a knife to open the neck of the sheep and slowly remove the entire skin, so that you cannot cut any of the areas.

After removing the sheepskin, blow air to expand the skin and fetus, then pour a small amount of clean oil, salt and water, and then tie the head, tail and limbs of the skin and fetus tightly. The skin and fetus that have been dried are yellow-brown and transparent, looking like a bulging cylinder.

Make sure there is no air leakage in the skin capsule, loosen the tail and release the air in the skin capsule and set aside.

Not everyone can make sheepskin sacks, and it is not easy to prepare so many sheepskin sacks in a short period of time. It can be imagined that many skilled craftsmen have spent a lot of time.

The tied sheepskin rafts were spliced ​​together by soldiers and turned into a floating bridge to extend little by little to the south bank. In order to ensure that the floating bridge is straight, some soldiers first swam across the river and pulled two thick hemp ropes on both sides of the water to fix both ends of the sheepskin raft.

At the same time, soldiers stood on sheepskin rafts and drove wooden stakes into the river to fix the pontoon bridge spliced ​​by sheepskin rafts, so as to avoid the pontoon bridge swaying left and right when a large number of soldiers crossed the river, causing the pontoon bridge to sway left and right and disintegration.

In order to minimize movement as much as possible, the sledgehammer used to punch wooden stakes wrapped around the cloth. Except for a few special small lamps, there was no extra trace of fire on the entire bridge construction site. Everything was to avoid attracting the attention of the Yanling defenders as much as possible.

The soldiers must set up the pontoon bridge before the limited time arrives so that when their main force starts to attack the city, some of the troops can cross the river to reach the south bank and cut off the retreat of the Yanling defenders, so that they cannot quickly send envoys to intimidate and turn them into an isolated city.

The supervisor who was supervising the progress of the bridge took out his pocket watch and looked carefully with the sometimes uncommon moonlight for a while. He probably confirmed that the floating bridge could be built when the deadline came.

While he breathed a little relieved, he couldn't help but look to the northeast.

That is the north of Yanling City, where the army of our side is about to launch an offensive.

Yanling is located on the north bank of the Bingshui River, so when facing enemies from the northeast, they cannot directly use Bingshui River as moat. Yanling is now a place where the two armies compete. The defenders dug trenches in the north of the city and lead Bingshui into the interior to serve as moats.

For the attacking party, if they want to attack the city from the north, the siege equipment must first cross the moat moat. Even if the soldiers carry simple ladders to attack the city, they must first build a bridge on the trench.

Now, since we choose to launch a sudden attack in the early morning, it means that the siege team has only a simple ladder. When the defenders in the city react completely, they should quickly cross the trenches, climb the city with ladders, and control the city.

It is easier to build a large number of simple cloud ladders than to secretly build a floating bridge on the water, but it is much more difficult to quickly attack the city with these simple cloud ladders.

The general looked at the pocket watch and Yanling City, and couldn't help but sweat: Can this action be completed smoothly?

......

In the north of Yanling City, a general came hurriedly, following several sects. They walked on the street without ignition and passed a row of straw huts under the corner of the city wall. The straw huts were covered with soldiers sleeping in armor, everyone was wrapped in bedding, and their heads rested and weapons were sleeping.

The general walked along the steps towards the city, slowing down as much as possible to avoid the friction of the armor leaves being too loud and being too harsh in a relatively quiet night.

When he arrived at the dark city, he and his team were both hunched and turned into a battle shed.

There were several soldiers in the battle shed, lying behind the battlements, looking out of the city through the arrow hole. When they saw the general coming, they moved aside so that the other party could peek outside the city.

The general lay behind the battlement, took out a thousand-mile mirror, stretched out the arrow hole, and looked carefully in the faint moonlight for a while. He saw that there was indeed a little shadow in the field outside the trench below the city. It was not that the normal weeds swayed in the wind, but that it was obvious that someone was moving.

There are many, at least thousands.

At this moment, as long as you are not a person with a brain problem, you can figure out what so many people outside the city are doing. The general takes back the Qianli Milestone, takes a deep breath, looks at the soldiers, and slaps his thighs hard:

"This thief is indeed here!"

The soldiers were both excited and worried when they heard this: "General! The other party seems to be preparing to steal the city. When will we wait?"

"Don't worry, wait a little longer, they start attacking later, that's the time to take action!"

The general clenched his fists and said confidently. At this time, several soldiers turned into the battle shed, bringing the latest news: According to the observation post in the northwest corner of the city, it seemed that someone was building a floating bridge on the surface of the Bulaishui River, nearly two miles upstream.

Because the distance is long and the moonlight is sometimes gone, I just look at it in a vague way and thinks it is strange on the river surface, so I made this kind of guess, but because I didn't send someone to find out, it's hard to say whether this guess is right or not.

"Don't send someone to avoid disturbing this thief!"

After the general finished speaking, he used a thousand-mile mirror to observe the movements outside the city. Although he could not see the movements in the wilderness, he was like a hunter who had been squatting for a long time. He was very excited when he saw the prey that was about to fall into a trap, so he wanted to see with his own eyes how unlucky the prey was.

Like the snowflakes flying willow catkins, the north wind seemed to have stopped. At this time, the east was faintly shiny, and it seemed that it was not far from dawn. Before dawn came, the other party would definitely take action.

A few miles away from the southwest suburbs of Yanling City, on a hill, Yuchi Youqi looked at the eastern sky that seemed to be beginning to show off. Then he picked up the Thousand Mile Mile Mile and continued to observe the movements of Yanling City in the northeast. Among the woods behind him were many soldiers sleeping in armor.

According to the signal that the Yanling defenders had just used lights to convey, the opponent seemed to have a lot of troops, which meant that the trap he had carefully planned finally came to his prey.

The other party was like a fierce tiger, about to pounce on the unprepared Yanling, but he didn't know that the hunter who had been lurking for a long time was ready.

Yuchi Youqi should have been in Luoyang, but at this time he appeared near Yanling on the banks of the Bingshui River. He held the Qianli Mile Mile Mile and looked at the dark city of Yanling. Although the weather was cold, his heart was very hot:
Chapter completed!
