With Zhang Tang's reinforcements joining in, Yuyang can easily be defended.

The enemy fought for more than an hour and found that they could not shake Yuyang, so they had to retreat to reduce the battle losses.

By this time, it was already evening.

Zhang Tang inspected the city tower and found that part of the city wall had been smashed by Yan's trebuchets. Due to the cold weather, repairs are now a bit difficult, and there is not enough stone in the city.

If the city tower is seriously damaged, it is easy for enemies outside the city to find an opportunity to break through the city.

After looking around, he looked at a piece of ice that had turned from stagnant water in front of him. He suddenly had an idea and said loudly: "Gather 20,000 people and prepare a lot of water to water the city wall tonight."

"Why is this?"

The guard asked in confusion.

Although there is no shortage of water in the city, it is somewhat abnormal to spend so much manpower on watering the city walls.

Zhang Tang pretended to be mysterious and said: "You will know tomorrow morning."

Twenty thousand soldiers will be arranged soon.

The water that had just been drawn from the wells would not freeze. They held torches and worked all night. There were several wells in the city, and people were constantly drawing water. Some were responsible for delivering water to the city towers, and some people were supplying water to the city walls.

Water.

The watering operation lasted all night and was completely completed before dawn.

Zhang Tang, who had not slept all night, climbed up to the city in anticipation and saw that the outer perimeter of the city wall was covered with a layer of ice. It was not only solid, but also very slippery. The weather was cold and water poured on the city wall would easily freeze.

"General Zhang, this is a good plan!"

The guard immediately understood the function of these ice layers and was amazed.

Zhang Tang just smiled and kept people on guard.

At noon.

The enemy launched another attack, but when they first reached the edge of the city wall, they were all dumbfounded.

Where did this layer of ice covering the city wall come from?

"No matter what, attack the city first!"

The general of the Yan army said loudly.

They all want to take down Yuyang as soon as possible and cannot delay it any longer.

The Huns eagerly wanted to rob Qin's food for the winter after breaking the city, but when they saw the ice outside the city wall, everyone stopped. After a while, they couldn't care less and followed the Yan army.

Go and attack the city.

However, the ice on the city wall was very slippery, and there was a lot of water on the ground, which was also frozen. As soon as they walked over, many people slipped and fell. Even if some people did not fall, they wanted to set up a ladder, but with such a tower, the ladder

It cannot be fixed and cannot be climbed up.

"Chisel that ice!"

Someone else said.

They picked up the guy to cut through the ice, but Zhang Tang would not let them do so and shouted: "Shoot!"

A large number of arrows fell from the sky.

There were also stones, etc., which were smashed down hard, and many enemies who were close to the tower were immediately killed.

"Trebuchet!"

The generals of the Yan army shouted loudly.

Several trebuchets were pushed up to hit the ice from a distance, and the effect was very good. A large piece of ice was shot down, so the enemy approached again carrying a ladder.

"General Zhang, what should we do?"

The guard asked worriedly.

Zhang Tang thought for a moment, then waved his hand and said, "Keep asking people to water the water!"

Buckets of water were quickly picked up.

The soldiers poured water on the towers and on the enemy soldiers who wanted to climb.

As soon as the water went down, as the cold wind blew, the temperature became extremely low, and there was a feeling that it was about to freeze. Those enemies who climbed the tower and were soaked were shivering in the cold wind.

Have to tremble.

"So...so cold!"

Someone said in a trembling voice that they would never dare to climb up again.

Another person said: "It's freezing... it's freezing so quickly!"

They saw that their clothes, as well as the ladder, had begun to freeze where they had been exposed to water, and it was miserable. They all wanted to get down from the ladder and go back to warm themselves by the fire.

Zhang Tang saw that the water splashing was effective and ordered the soldiers to speed up the water splashing.

Water splashed all over the sky and hit the bottom of the tower. The soldiers who were attacking the city were so cold that they trembled all over. In the end, they couldn't even hold their weapons steady, so they had to retreat again, and they had to worry about getting sick.

"The general's plan is very clever."

The guard said excitedly.

Zhang Tang is basically certain that the crisis in Yuyang will be alleviated in a month or two. As for what changes will happen after the ice and snow melt, it is temporarily impossible to predict.

"The general must have a way."

Zhang Tang thought to himself and quickly wrote a letter and asked the people from Heibingtai to send it back and tell Bai Zhong about the situation here.

at the same time.

Inside the prison in Linzi.

Qi Wangjian was wrapped in a tattered quilt, but its ability to keep warm was poor. The cold made his body tremble slightly. Next to him was Hou Sheng. The other family members were locked up in other places. Tian Chong did not allow them to reunite.

"Prime Minister."

Qi Wangjian said suddenly.

With half-closed eyes, Hou Sheng stood up quickly and asked, "Your Majesty, what's wrong?"

"While being locked up, I suddenly figured out something."

"Although I am fatuous and have little ability, I am not a fool. I think too much about some things, and if I don't ask them clearly, I will feel uncomfortable."

"Prime Minister, do you think that's right?"

Qi Wangjian looked straight at Hou Sheng.

Hou Sheng felt a little guilty, but he could only nod his head and said: "The king is right, but what does the king need to ask his ministers?"

Qi Wangjian asked: "Have you colluded with Qin for a long time?"

"Your Majesty, my lord...my lord..."

Hou Sheng knelt down nervously. He wanted to deny it to the end, but at this point, it no longer mattered whether he admitted or denied it. It was considered acquiescence now.

"I should have thought of it a long time ago."

Qi Wangjian sat up as he spoke, leaning his back against the wall, as if he didn't care at all.

"Who?"

At this time, a cry of surprise came from inside the prison.

However, the shouting lasted for a while and was quickly silenced. Several men in black came in, killed all the guards in the prison, and finally came to King Qi's cell.

"Who are you? Is Tian Chong trying to kill us?"

Hou Sheng was panicked and frightened. The more he thought about it, the more he realized it was possible.

Qi Wangjian said calmly: "It shouldn't be Tian Chong's, otherwise he wouldn't have killed the guard."

They were all from Heibingtai, and they didn't bother to talk nonsense with Hou Sheng. They found the key, opened the cell door, and released them all.

"Who are you?"

Hou Sheng asked in disbelief how someone could let him go for no reason.

The people in Heibingtai still didn't say anything. After finishing all this, they immediately left the cell.

Qi Wangjian narrowed his eyes. After being the king of Qi for so long, he still had good discernment skills. He said to himself: "I heard that Qin State has a black ice platform that can do anything. It is true!"

"They are from Heibingtai. Qin wants to save us?"

Hou Sheng was a little surprised, and soon wanted to understand why Qin would save them.

Of course it was to deal with Tian Chong.

Qi Wangjian took a look at his family and strode out of the prison. He saw only a few of his veterans waiting outside, as well as a large number of soldiers and horses.

"My lord, I await your return!"

Those old ministers were not convinced by Tian Chong, so they all came to greet him at this time.

When Hou Sheng saw it, his eyes widened.
Chapter completed!
