Cao Cao finally agreed to Cao Shuo's suggestion.

Back outside the city, Cao Shu ordered to head towards Tongguan immediately.

Following Cao Shu, Ma Teng turned around from time to time and looked at the head of Chang'an City.

The Cao army battle flag was flying at the top of Chang'an city.

Although the battle flags under Cao Cao are somewhat similar to Cao Shuo, they are not the same.

Looking at the battle flags flying above the city, Ma Teng felt a little uneasy.

"How did General Ma plan to persuade Meng Qi?" Cao Shuo asked Ma Teng.

"If Meng Qi dares to go out, I will go and meet him in person." Ma Teng said: "I don't believe that he dares to kill me."

"Meng Qi is filial, of course he dare not kill General Ma." Cao Shuo said: "But it is not appropriate for you to go out in person. If Meng Qi robs you, my father will probably not let the other two young generals go."

Ma Teng's face turned a little ugly.

He asked Cao Shuo, "Young Master went to see Cao Gong, did Cao Gong say something again?"

"It's true." Cao Shuo did not hide it: "My father sent someone to capture General Ma just now, but I tried my best to stop him, so I persuaded him."

"Don't Cao wants to kill me?" Ma Teng's face became even darker.

"General Ma should not take it to heart, after all, Meng Qi did this inappropriately." Cao Shu said: "If it were General Ma, he would be like his father."

Ma Teng nodded and sighed a long time.

After leaving Chang'an, the army walked for two or three days before reaching Tongguan.

Ma Chao and Han Sui had already led the Xiliang army to pass the pass, and the general Ma Wan under Han Sui was guarding Tongguan.

Ma Wan has no kinship with the Ma Teng clan.

He is just a member of Han Sui's command.

Cao Shu came to Tongguan, and the gate was closed, and Ma Wan stood at the juncture and looked at the approaching Cao army.

Cao's army had a lot of supplies, and when they arrived at the gate, the soldiers unloaded the supplies.

Looking at Cao Jun who was unloading his baggage, Ma Wan felt puzzled.

The supplies that Cao's soldiers unloaded from the carriage were many woods of different shapes.

After unloading the wood, Cao's army was posing at the city wall from afar.

The horse was confused and had no idea what Cao Jun was doing.

I saw Cao's army unloading the wood from the carriage, and some people assembled it on the spot.

It was not until the wood was assembled halfway, and the horses realized that they were assembling a catapult.

"Cao's army is about to attack the pass, the whole army is on guard!" Ma Wan shouted loudly.

The Xiliang army at the pass were all nervous.

From the style of the battle flag, they could recognize that it was Cao Shu.

Some Xiliang Army had fought against the Huns with Cao Shu. They knew Cao Shu well and knew that this time they were a difficult enemy they met.

The former allies have now become hostile, and it is really difficult to understand that the impermanence of the world is not easy to understand.

Cao Jun unloaded his caravans of staff and assembled them into catapults.

The size of these catapults is much smaller than the fixed siege equipment temporarily built outside the city.

Their location is farther than the tall stone-treating instruments.

Looking at the catapult cart assembled by Cao Jun, Ma Wan was very confused.

Can such a small catapult cart throw stones to the pass?

He was suspicious in his heart, but Cao Jun didn't seem to notice that the catapult cart was too far away from the gate and was still assembled one by one.

All day, Cao's army was assembling a catapult.

Although the horse at the pass was worried that the catapult would cause great damage to the city wall when it was built, he had few soldiers and horses under his command. He also knew that Cao Shu's soldiers were all warriors, so he did not dare to leave the pass and fight easily, so he could only watch Cao's army prepare in front of the station.

Cao's military camp within the pass.

Cao Shu stood outside the tent and looked at the Xiliang army battle flag flying at the pass.

Behind him were his aides and generals.

Ma Teng and his son were also with him.

"General Ma, are the defenders at the passport members from your Ma family?" Cao Shuo asked.

"No." Ma Teng said: "From the battle flag, it should be Ma Wan, the general of Han Sui."

"How is horses playing?" Cao Shuo asked.

"It's just ordinary." Ma Teng said: "He's just a longer time following Han Sui."

"Han Sui is going to lose an old subordinate this time." Cao Shuo smiled slightly.

He smiled confidently and calmly.

Ma Teng didn't feel very arrogant at all.

The longer he had been in contact with Cao Shu, the more he felt that the confidence of the Cao family's son was not unreasonable.

When Cao Shu went on the battle, he was always invincible. No one who was an enemy of him ended up in the end.

If the horse guarding Tongguan refuses to surrender, the only thing waiting for him is to destroy the people.

Cao Jun made preparations before the station for two days.

Dozens of catapults were set up outside the pass, but Cao's army did not find stones from nearby, but placed two wooden boxes next to each catapult.

Looking at Cao Jun from afar, Ma Wan became even more confused.

What exactly do they want to do when they set up a catapult cart, but they don’t move the stones?

When the last catapult car was built, Cao Shuo brought several generals to the front.

He asked the officer in charge of commanding the throwing chariot, "How are you prepared?"

"Report to the young master, you are ready." The officer replied: "You can launch an attack at any time."

"Then let the horse play with our bombs." Cao Shuo smiled slightly and ordered the officer.

The officer responded and shouted loudly: "Young Master has an order, launch an attack!"

All the catapults aimed at the barriers.

The Cao army soldiers pried open the wooden box and moved out round black balls from it.

The size of the black ball is much smaller than the boulders used in the past.

Looking at Cao Jun who was about to project, Ma Wan was even more confused.

What role can only use such a small black ball without a huge rock?

Cao Zirong is invincible. Has he been blinded by too many victories recently and even forgot how to use the catapult car?

I was muttering whether Cao Shu was stupid, and horns were heard from Cao's army camp.

As the horn sounded, the catapult made a sound of ejection, and the black ball flew up in the air and smashed towards the city wall.

The ball is not big. When it is flying in the air, the horse can even see that there is a fire on each ball.

A ball falls at the juncture.

When it hit the wall, it bounced to the feet of several Xiliang troops.

I had never seen such a strange thing before, so a few Xiliang soldiers came up curiously.

The ball is small, not as big as a human head, and a spark is flashing above it.

When the Xiliang Army saw this ball, they were puzzled.

Such a small thing is just a white mark when it hits the city wall. How can it be checked?

Just as he was wondering what Cao Jun wanted to do, the spark on the ball had already burned to the roots.

As the spark disappeared on the surface of the ball, a loud bang suddenly sounded.

Several Xiliang troops who were watching the ball were driven out of the city with a loud noise.
