Facts have proved that Meng Hun underestimated his Lord.

Only the wrong name, not the wrong nickname.

What's Jiang Pengji's nickname?

850000 live viewers unanimously recognized the human battlefield strangler.

Give her an invincible machete, and she can tear down a war fortress alone. It's not as strong as a person.

The terrain of Hanchang pass is steep, easy to defend and difficult to attack. Soldiers don't have much focus. It's difficult to charge or retreat. The enemy occupied the advantage of the checkpoint and gradually pulled back the disadvantage. The battlefield seemed dangerous, but the cold Chang pass was still solid and difficult to shake.

"Lord, you can't go on like this. Although all the soldiers climb the wall with the help of the ladder, the wall is narrow and it's not easy to form an array -"

The city wall of hanchangguan is narrow, and there are too few places to stay. The number of soldiers climbing the wall at the same time is not large.

The enemy is different. They climb the wall from behind the pass. The terrain is relatively open. They can kill and retreat the people who climb the wall by virtue of the number advantage.

Looking at our bodies falling from the city wall, not only Feng Zhen's face was not good-looking, but Jiang Pengji's expression was also gloomy.

If it is an ordinary city, once the city wall is lost, the victory or defeat is basically a foregone conclusion.

However, Hanchang pass is known as the gateway of three natural hazards in Cangzhou, which naturally has a certain reason.

If it were so simple, Meng, who occupied Cangzhou, could not stand and be arrogant for hundreds of years.

Jiang Pengji decisively ordered, "Zishi, order the soldiers of the city wall to retreat!"

If we continue to consume, our losses will be greater and greater. It's just a meaningless sacrifice. It's really not worth it.

Feng Zhen's complexion changed dramatically, and the bottom of his eyes seemed to flash through strands of struggle.

But for a moment, his eyes turned firm, "promise!"

"No -" Cheng Jing stops Fengzhen and grits his teeth. "If we withdraw at this time, our momentum will be greatly reduced, and we will be unable to break the pass at that time."

"As you can see, even if we occupy the city wall, we still haven't shaken the enemy's defense line. Knowing that climbing the wall is useless, going up is death. Why should I let my soldiers climb the wall and die?" Jiang Pengji said coldly to Cheng Jing, "I'm going to break the cold Chang pass today!"

Jiang Pengji has an unusual and decisive character. Once she makes up her mind, there is no room for turning around. The word indecision is insulated from her.

"Vanguard army, I am the commander."

Jiang Pengji's attitude is firm and can not be resisted by others.

The battlefield is changing rapidly, and the order is delayed. Even if it is only a minute and a second, innocent soldiers will still pay their lives for it.

Jiang Pengji shows her identity. Cheng Jing can only bow her hands and choose to obey with a heavy heart.

Even though Jiang Pengji is not the Lord of Cheng Jing, as the other party said, Jiang Pengji is the commander of the vanguard army.

On the battlefield, the command of the commander is above all else!

Jiang Pengji ordered to give up the attack. The soldiers who had climbed the wall could only fight and retreat and give up the hard won results.

After several years of military training, Jiang Pengji's soldiers can absolutely obey orders and prohibitions, and their momentum has little impact.

In contrast, the soldiers sent by Huang song performed slightly worse. The original high-profile momentum was much lower, and the retreat was not decisive enough.

Jiang Pengji chose to retreat. The enemy troops who guarded Hanchang pass were filled with tears of joy, and the shouting voice made them energetic.

Listening to the roar of mountains and seas on the city wall, Jiang Pengji bit her teeth and asked Fengzhen.

"Is the stone throwing frame ready?"

Feng Zhen replied, "it's already set up."

The catapult is large, with obvious targets and difficult to move. It is rarely used except for siege and frontal confrontation between the two armies.

However, as a technology expert, how could Jiang Pengji not find a way to solve this problem?

The catapult that appeared at the beginning of World War I in Cheng'an county has been improved for several generations and can basically adapt to wars in various terrain.

Most importantly, the catapult can be disassembled and transported, and it is not complicated to build.

Even though the terrain of hanchangguan is narrow and steep, as long as there is a relatively flat place, the catapult can be built and put into use.

Since you can't climb the wall to win the pass, you'd better tear it down!

When Jiang Pengji sent someone to attack the city, she told the rear to build a catapult. Now it has been put in place.

"When the explosives are made, they will blow up wherever they hit. What natural danger portal will be razed to the ground!"

Jiang Pengji clenched her teeth secretly. If the battlefield was not chaotic, she really wanted to dismantle the two heavy copper doors of Han changguan with her double axes.

Cheng Jing also noticed the situation in the rear, and his face suddenly sank.

The terrain of Hanchang pass is so steep that heavy objects such as stone catapults can't be transported at all——

Thinking of this, he thought of the baggage cart behind the pioneer camp. Was it because the baggage cart contained nothing else but parts of the catapult? Is it difficult for Liu Xi to have the help of the elite disciples of Mohism in his account?

Cheng Jing guessed half right.

Jiang Pengji does have Mohist disciples here, but Zhang Ping is better at livelihood equipment, and Shao Guang focuses on water conservancy.

Most of the time, Jiang Pengji provided ideas for the improvement of siege equipment, and Zhang Ping led craftsmen to try to improve them one by one.

"Give me the rocket -"

Jiang Pengji asked people to get her own heavy bow. This bow is extremely heavy. From the bow body to the bow string, it is made of special materials by craftsmen. According to their calculations, if you want to pull the bow completely, the person who pulls the bow must be at least an eight foot strong man with the power of four stones.

Jiang Pengji is short in arms, but she is tall enough.

As for the power of four stones to open the bow?

Naturally enough.

She touched the ground with one foot and the other against the bow, pulled the string with her right hand and lit the special arrow.

The whole body accumulates strength, and the heavy giant bow opens into a full moon under the guidance of Juli.

Buzzing——

A heavy hum sounded, and the huge arrow left the string and flew towards the wall of hanchangguan.

The arrow made of refined iron fell into the gate tower of the city wall, and the spider web crack spread around, and the door beam collapsed.

"Aim at that place - smash it for me!"

Jiang Pengji has strong eyesight at night. She can clearly see the situation on the wall of hanchangguan City, but others can't.

They couldn't do it, let alone the catapult Gunners behind the army.

Cheng Jing looked at the whole process, holding his hands tightly in his sleeves, and the neatly trimmed round nails left crescent marks in the palm of his hand.

Jiang Pengji threw the huge bow to the servicemen aside, and her anger still lingered around her. The guards on the wall didn't have time to be happy. One boulder after another fell from the sky and hit the gate tower, wall buttress and the mountains on both sides of Hanchang pass——

The smile on the guard's face of Han changguan hasn't converged yet, and the falling boulder caught them by surprise.

This, this is totally different from the script they expected!

Jiang Pengji looked at the situation on the city wall. Her depressed mood finally improved, and her residual anger turned calm.
