"What?!" Drag Lei to stand up from the chair, and then looked at the top of the city, just in time to see Xue Rengui with a rocket in his hand.

Suddenly, Tuolei and Zhebie both understood.

"Mingjin retreat!"

The two people yelled out in the loudest voice since birth almost at the same time.

However, not to mention that Xue Rengui is fully prepared here, even if it is not fully prepared, the Mongolian army will not be able to withdraw for a while.

Because it is already crowded?

Whoosh!

Xue Rengui's rocket flew out, dragging the fierce wind, and finally landed accurately on the isolation zone formed by kerosene.

The fire ignited instantaneously, and an isolation zone consisting of the fire was completely formed.

Not to mention that the Mongolian army is already full of kerosene, even if there is none, don't even want to withdraw.

"Throw down the lit firewood!" Xue Rengui continued to give orders.

Oil pots were already burning everywhere on the city walls, and naturally, the firewood was lit. Thousands of firewood were thrown down.

There were indeed too many troops below, and they were blocked by the fire outside, and they couldn't get away at all. The firewood fell directly on them.

The firewood quickly ignited the kerosene on the Mongolian army. One fire broke out, followed by thousands of places. Then the fire spread to the surrounding area, wrapping the entire Mongolian army under the city wall. In the sea of ​​fire.

It was also at this time, the time was almost five hours, and Ye Feng and others walked up. They thought it was definitely a very difficult moment to defend.

But I didn't expect that it would be such a scene.

Tens of thousands of Mongolian troops were struggling in the sea of ​​flames, crying and howling, each of them sounded like evil spirits crawling out of hell.

And that appearance is even more miserable!

The intense fire and blazing temperature made the soldiers above the city wall flushed, and the smell of burnt meat was floating in the air.

Looking at the miserable appearance of the Mongolian army in the fire below, the defending army did not feel uncomfortable. Instead, there was a strong sense of pleasure. The previous style of the Mongolian army caused the people present to no longer see them as human beings.

For the scene under the city wall, the night wind is not uncomfortable.

A rough calculation shows that there are at least 50,000 or 60,000 people surrounded by the fire. He is very curious how Xue Rengui did it.

After knocking down the remaining enemies, all the defenders on the wall were free. Xue Rengui quickly walked to the front of Ye Feng, "Prince!"

"Yeah." Ye Feng nodded and praised, "Good job."

"Small tricks are not worth mentioning." After stepping off the battlefield, Xue Rengui restored his humility and conservativeness.

Ye Feng got used to his character, and asked, "I’m very curious. The Mongols are not wooden piles. At the beginning, the people on the periphery must have time to disperse, and the soldiers can’t throw the can of fire oil too far. You How did it do it?"

"Use a stone thrower to throw the isolation belt, cut off its retreat first, and then let the soldiers throw it." Xue Rengui said simply.

"So that's it." Everyone had the same confusion, but now they all understand.

The range of the stone thrower is naturally sufficient, but this thing is used to throw stones, and everyone did not expect it for a while.

"Okay, let's take over, you two will go down and rest first." Ye Feng said to Xie Xiaofeng and Xue Rengui.

"Thank you, Prince!" Xue Rengui and Xie Xiaofeng responded.

After five hours in Lien, they were not too tired, but they retreated.

They went down, and even the soldiers who had guarded the city before retreated, and new soldiers took over.

Xu Maogong looked at the sea of ​​fire below, then looked at Ye Feng, and said: "With such a big fire, the battle will be impossible for a while. Let's do something else.

"Sir, what's the plan?" Ye Feng asked.

"It's not a strategy, it's just an extra guarantee, maybe it can also exert some unexpected miraculous effects." Xu Mao justified.

"What is it?" Xiaolongnv asked. This girl is now more curious. She asked, and Ye Feng won't repeat it.

Xu Maogong pointed to the city and said, "I am going to add another inner city wall at that location. The more than nine thousand people who happened to be rescued by us insisted on helping us defend the city, but they did not have formal military training. Some people did. If you can help, some people may add to the chaos, so let them do this kind of thing."

Ye Feng nodded, "It's only their words that I'm afraid that the speed is not fast enough. You can start the people of Hequ County. For every fifty cents of labor, you can send an additional 50,000 soldiers to help. The construction will be completed in one day."

"Okay!" Xu Maogong retreated.

Ye Feng looked at the fire field outside the city again, because there were no combustibles except for people, kerosene and some siege equipment. The fire gradually began to go out.

opposite.

Tuo Lei and Zhe don't look at the scorched ground on the front line, they are all dying.

In the first round of attack, they pushed up 70,000 soldiers, and the battle was damaged in the early ten thousand years, which was completely acceptable.

But this fire is 50,000 to 60,000 people, so I totally accept it.

Without the barrier of flames, Tuo Lei and Zhebie once again saw the night wind on the city gate, and shouted angrily: "The people on the city gate listen to me! You have completely angered this king! The anger is no longer Tu Yicheng. It can be extinguished! My Mongolian warrior died 70,000. Once you enter the customs, you will definitely want you to exchange 7 million people for it!"

"You know what ghosts are called ghosts? You have the ability to attack now?! We are waiting." Li Mochou went back.

"Senior Sister, this should be the prince's reply, what are you robbing?" Xiaolongnv pulled Li Mo worry.

"I'm sorry." Li Mochou said to Ye Feng.

"It's okay, I happen to be too lazy to talk to the beast." Ye Feng touched Li Mochou's head and said.

This ghost girl is so cute in this world, maybe because of keeping up with the night breeze, her personality has become very cheerful and likable.

"Hehe, let me just say it, the prince is the best." Li Mochou said, he shook his arms holding Ye Feng, rubbing his face against it.

There were a lot of people present, and suddenly coughed.

"Mo Chou, don't be rude." Lin Chaoying couldn't help but cried.

"Oh!" Li Mochou just let it go.

opposite.

After getting Li Mochou's answer, thunder became more angry.

puff!

A mouthful of blood spurted out, pointing his finger at the city wall to curse, but he couldn't curse at the end, because he could no longer raise his breath and make a loud noise.

Two cronies stepped forward, one on the left and the other supported Drag Thunder, "The prince calmed down."

"The humble Han female slave dare to talk to the king like this, pass the order, remember her appearance, and wait until the king is caught alive and asked her to be a military prostitute!" Tuo Lei said, out of breath.

Yes!

A confidant really passed this information down.

Tuo Lei and Zhe Bie returned to the Central Military Account, and it took a long time to relax.

"The opponent's guarding ability is not weak, it seems that we can only use special means!" Tuo Lei said coldly.

"Which one to use?" Zhebie asked.

"Plague!" Tuo Lei spit out two words.

In Mongolia's current territory, almost 80 cities were captured by this thing.

"Good!" Zhebie went out in response, and then gave orders to his subordinates.

Soon these soldiers went to a warehouse and took out the tightly sealed jars.

Then batches of Mongolian soldiers transported these jars to the rappel.

On the city wall, the night wind crowd immediately saw it, and the stone thrower on the opposite side began to launch.

Seeing these jars, Yefeng only assumed that they were filled with corpse oil, and quickly issued an order, "Hide, don't let this jar hit."

Clang!

The jar eventually fell to the ground, but it was not corpse oil inside, but a pile of rotten grass with stinking nets. The jar broke when it fell to the ground, and the stinky grass inside was scattered.

"My grass! These Mongolian dazi are so disgusting!" The soldiers could not help but yell at the smell.

Just as the soldiers yelled and cursed the Mongols, the voice of the system rang.

System: "Emergency alert! According to system testing, this grass is called the planet's unique black rock grass. Yersinia pestis will grow after the grass is fermented. Please deal with it as soon as possible, otherwise the consequences will be disastrous!"

"Damn it!" Ye Feng didn't expect the Mongols to use this hand again.

Yersinia pestis is a virus that can spread through the air and can cause a wide range of plagues, which is called the Black Death.
