The setting sun in the evening casts long shadows on the plain.

The military flag fluttered in the breeze, and there were noisy sounds from the military camp ahead.

Someone is holding a sumo wrestling match, and people from both sides are cheering their own people up.

Sumo wrestling was very popular in the Song Dynasty. It was not two fat men wrestling there, but two strong men.

As for sumo wrestling in Japan in later generations, it was learned from the Song Dynasty and made changes.

Not only sumo wrestling, but also Cuju is held in some military camps.

In addition, polo is being played in some places. Soldiers took off their armor, rode horses, and held polo sticks, galloping across the open space.

The Logistics Department was unloading the grain that had just been transported, as well as a batch of medicinal materials.

Zhang Xian was holding a picture at this time, frowning and looking at it for a long time, he said: "Can this thing really destroy the city wall of Hejian City?"

Li Chunsheng, a doctor in the Ministry of Industry, said: "Zhang Dutong and Wu Shuai have verified that Wu Shuai used it to defeat Baode's city wall two months ago and captured Zhe Keqiu alive. I heard that Zhe Keqiu is about to arrive in the capital."

"Wu Jie used it to defeat Zhe Keqiu?"

"I just mean to knock down the city wall and end the war early."

Zhang Xian looked at the group of people in the engineering camp who were busy in front of him. He still didn't believe it. Not only did he not believe it, but Yao Zheng didn't believe it either.

Yao Zheng said: "Do you think I have never seen a trebuchet?"

Li Chunsheng quickly explained: "This is the latest trebuchet produced by the Ministry of Industry. It is larger than the previous trebuchets and can be thrown farther."

"Is it far enough to break through the wall of this river city?"

Li Chunsheng looked at the brick walls of Hejian City and felt a little unsure. He said, "But it is indeed more powerful."

"Then we'll wait and see!" Yao Zheng laughed.

Obviously, Yao Zheng didn't quite believe Li Chunsheng's words.

Even Zhang Xian didn't believe it. The reason why they cooperated with Li Chunsheng was because they had orders from above, which were orders directly issued by the Military and Political Council.

Twenty of these trebuchets must be completed.

The engineering battalion is currently being built overtime day and night.

"I know, thank you for your hard work." Zhang Xian was still very polite.

Li Chunsheng saluted and said: "We are all cooperating with Commander-in-Chief Yue. We are willing to do the hard work of dogs and horses."

Zhang Xian nodded and left with the people.

Yao Zheng muttered: "If that thing is really useful, I'll slap that Li Chunsheng twice in the face!"

The surrounding soldiers were silent, obviously hearing what Yao Zheng said.

Yao Zheng was not afraid either. He said to the people around him: "You have all heard it. If that thing is really that amazing, remember, pull me in front of Li Chunsheng and let him slap me twice."

The soldiers did not dare to say a word, but Yao Zheng said: "What are you afraid of? I am a man who keeps his word!"

Everyone nodded in agreement.

Zhang Xian said: "Okay, stop talking, after all, they are here to help us."

At such a close distance, Li Chunsheng must have heard what Yao Zheng said just now.

"I know they have good intentions, but instead of building those trebuchets, why not build more goose carts? Can the trebuchets still be able to throw soldiers into the city?"

Yao Zheng's impression of the trebuchet is still in the past.

In the past, when trebuchets were used to attack cities, they mainly played a psychological role, and their actual destructive power was not very great, especially for city walls made of bricks.

In the evening, Wanyan Po Lu Huo ran to the top of the city to inspect.

The guards of the Jin Army were all twelve times more energetic.

"Everyone is guarding it!" Wanyan Po Lu Huo yelled loudly, "Soon the army of the Second Prince of Yanjing will go south and kill all those Song dogs!"

Wanyan Po Lu Huo's voice echoed at the top of the city.

Everyone, who was originally tired, cheered up a little after hearing this.

"Report! Dutong, several scouts reported today that the Song Army is building a trebuchet."

"Trebuchets are nothing!" Wanyan Po Lu Huo dismissed it, "This Hejian City is made of stone bricks and is extremely strong. The trebuchet can even smash a hole under my feet!"

He pointed to his feet and stepped on them a few times.

The people around laughed out loud and obviously expressed disdain for Song Jun's trebuchet.

Early in the morning on July 15th, Li Chunsheng ran to Zhang Xian's camp.

Zhang Xian and Yao Zheng were having breakfast. When Li Chunsheng arrived, Zhang Xian said politely: "Prepare one for Mr. Li too."

"yes!"

"Thank you Zhang Dutong, the trebuchet is ready."

"Have all twenty units been built?"

"Originally, many parts were manufactured in Tokyo and shipped directly over. Only some parts needed to be manufactured and assembled."

"You are creating things faster and faster now." Yao Zheng gnawed on the steamed buns with a smile on his face and touched his beard.

"The main reason is that Taifu Temple introduced the assembly line," Li Chunsheng said.

"We don't know anything about assembly lines. After the trebuchet is built, can we start building the goose cart?" Yao Zheng said eagerly.

"Can."

"We need fifty goose trucks. How long will it take to build them?"

"Ten days."

"It only took you three days to build twenty trebuchets, but ten days to build fifty goose carts?" Yao Zheng was obviously dissatisfied with the progress.

Zhang Xian said: "According to the information given by Commander Yue, the Jin Army's leader, Wanyan Yinshu, has disappeared. He may have gone back to seek help. The main force of the Jin Army in Yanyun should have received the news in mid-June."

Yao Zheng took over: "According to this progress, Yanyun's Jin Army has begun to gather in June. With the strength of the Jin Army, it can be assembled in July. If we cannot capture Hejian City, we will face the main force of the Jin Army.

.”

"I know that the engineering battalion is very hard now, but the critical war situation does not allow us to slack off at all." Zhang Xian said, "In order to support us, the Cangzhou General Production Department sent an additional 10,000 people, plus the previous 10,000.

Now there are 20,000 Cangzhou troops, and together with our more than 2,000 cavalry, they can fight against the Jin people, but what Commander Yue wants is to regain Hejian!"

Li Chunsheng said: "Zhang Dutong, this trebuchet is really effective. If you are in a hurry, why not use it first?"

Yao Zheng took a sip of apricot wine, slapped the steamed buns heavily on the table, and said, "Okay! I'll give it a try later. Are you ready to throw stones?"

"I even brought fire oil to smear it on the stone."

"Okay!" Yao Zheng stood up, "Bring me my armor!"

Early in the morning, as soon as the mist dispersed, the horns of the Song Army's camp sounded.

This immediately attracted the attention of the Jin army defending the city.

Soon, Wanyan Po Lu Huo was also woken up from her sleep.

"Du Tong! The Song army has attacked the city!"

"Song Gou is so active!" Wanyan Po Lu Huo got up angrily, put on his armor and walked towards the tower.

At such a critical time, Wanyan Po Lu Huo was still very cautious.
Chapter completed!
