By night, the fires in Bowangpo had been extinguished.

When it was dawn, Zhao Yun sent a wave of spies to investigate again, and after confirming once again that there was no Cao-Liu coalition army, Zhao Yun and Dian Wei led an army of 150,000 through the dangerous Bowangpo.

By dusk, an army of 150,000 had already arrived at Xinye City.

Zhang Fei, Guan Yu, and Xu Chu returned to Xinye yesterday.

Although the 40,000 troops who returned were forbidden to spread what Bowangpo had seen, the news still spread among the 150,000 troops in Xinye Castle.

The pressure is irrepressible.

However, Cao Cao and Liu Bei, the soldiers in their hands, the discipline will be much better by the Xiliang army.

Even if the news spread, there was no special disturbance in the army, and the generals and centurions below were able to stabilize their troops.

As for the news of Bowangpo, some people believe it, and some people think that it is the person who came back, exaggerating the rhetoric.

Cao Cao and Liu Bei, although they have also heard many reports, they are the same as Zhang Fei yesterday.

Before I saw it with my own eyes, I always doubted that the news sent back by the spies was somewhat exaggerated.

But after Zhang Fei read it yesterday, he knew all the news and did not exaggerate it.

If Zhao Jun's clay pots are large enough, no one in the world will be able to resist them.

Zhao Yun and Dian Wei did not rush to attack.

Set up camp outside Xinye City, and at night, it is also to strengthen patrols to prevent the Cao Liu coalition army in the city from sneaking attack.

Midnight!

The gates of Shinno Castle opened.

Xu Chu Guan Yu led more than 10,000 people and killed Zhao Jun's camp.

It was only when they approached the Zhao army camp that three clay pots smashed into their army.

Under the terrifying explosion in the dark night, there were hundreds of people and tens of thousands in an instant.

Guan Yu and Xu Chu knew that they had been discovered by Zhao Jun, so they immediately retreated.

Zhao Yun only strengthened his patrol tonight, and almost all of the 150,000 soldiers in the camp were sleeping and did not set up an ambush.

Otherwise, just let Guan Yu and Xu Chu in, and the two of them won't want to go back tonight.

Cao Cao only asked Xu Chu to try it, otherwise he wouldn't have sent only 10,000 people.

It's just that Guan Yu and Xu Chu retreated to the city with their men and horses, and the 10,000-strong army was already in chaos.

They were even more amazed than the 40,000-strong army that had been at Bowangpo yesterday.

The explosion in the dark night made them even more alarmed.

After returning to the city, the news spread quickly.

Cao Cao's face was very ugly.

Although he was in the city, he could hear the earth-shattering explosions even in the city.

The sound was so loud that even the people in the city felt panicked.

This was the first time Cao Cao had heard it with his own ears.

The Zhao military camp outside the city is only five miles away from the city.

Although it is impossible to say that the whole city did not hear the sound of the explosion of the clay pot, almost all the people in the circle of the city wall heard it.

Guan Yu and Xu Chu retreated with the men and horses, but Cao Cao didn't feel sleepy at all.

He called Cheng Yu, Xun You and others all over.

"You also heard the voice outside the city just now, is there a countermeasure?"

Let's not talk about how powerful the clay pot was, just this voice, Cao Cao understood that if ordinary soldiers heard it, it would inevitably make them frightened and affect their morale.

Cao Cao must first find a way to solve this point.

Otherwise, as soon as the army is bombed, it will immediately be chaotic, and I am afraid that it will not be able to command it at that time.

If there is a little stiffness in the process of commanding, it may be defeated.

Cheng Yu said: "You can let the soldiers all plug their ears with things." ”

Although blocking their ears will also affect the transmission of orders, at least they will not hear the explosions, so they will not be so afraid, and the army will not appear large-scale chaos or even rout.

Moreover, in the command of the army, many times it relies on the command flag, as long as you can see it, even if you can't hear it with your ears, it is not a very big problem.

If there is no other way, Cao Cao can only choose to let the soldiers plug their ears.

"If you want the soldiers not to panic, you need them to be familiar with the sound of explosions." Xun Yu said: "At present, only the ears are blocked. ”

Cao Cao didn't have gunpowder in his hands at all, so he couldn't let the soldiers get acquainted with it.

Even if they say something and tell them that they don't need to worry, the effect will not be great, and those who should be flustered will still panic.

It only took one night, and Xun Yu Cheng Yu and others couldn't find a better way everywhere.

At dawn, Cao Cao issued an order to the soldiers on the city wall to cover their ears with cotton.

All actions are commanded by the command of the commanding flag.

As for the soldiers in the city, there was no request.

However, as long as you climb the city wall, you must block your ears.

It's a bit of a cover-up and stealing the bell.

It's as if they blocked their ears and couldn't hear the explosion of gunpowder, and the gunpowder didn't exist.

Zhao Jun outside the city, after burying the pot to make food, Zhao Yundianwei ordered the artillery men to launch the catapult.

Again, I tried it twice with a stone before replacing it with a clay pot.

It's just that the number of catapults is limited, and ten clay pots are fired in one round.

And the Cao Liu coalition army on the city wall blocked their ears again.

The sound of the explosion could still be heard, but it wasn't so shocking anymore.

At least the Cao Liu coalition army on the city wall did not panic because of the explosion of the clay pot and fled without authorization.

After Zhao Yun launched several waves of clay pot bombardment, he withdrew his troops when he saw that it did not have much effect.

Zhao Hui's army of 200,000 remained in Nanyang.

However, he had already let Zhang Wang set off, carrying fifty catapults and a thousand clay pots to support Zhao Yundianwei.

Xinye is just a small city, although there are now 150,000 Cao-Liu allied troops in the city, but it is really difficult to block the Zhao army.

Even Cao Cao asked the soldiers on the city wall to block their ears.

But when Zhang Wang led the artillery battalion in place, hundreds of catapults bombarded the walls of Xinye indiscriminately.

Even if Cao Cao's army was doubling, no one would dare to stay on the city wall.

Although the catapult has undergone many improvements, it is still very bulky, and the road is not easy to walk.

Zhang Wang took a hundred catapults and took three days to reach the outside of Xinye City.

"My lord, it's dangerous today." Xun You looked at the hundred catapults lined up outside the city and said worriedly.

A few days ago, Zhao Yun only used ten catapults, which was enough for the Cao Liu coalition army on the city wall to deal with.

Now it has increased tenfold all at once, just thinking about the picture of more than a hundred catapults launching clay pots together, Xun Yu Chengyu and the others feel scared.

Even if the soldiers plug their ears so that they can't hear the explosion.

However, when more than 100 clay pots exploded at the same time, even if you could not hear the sound, you could see the earth-shattering fire, and your feet could feel the ground shaking.

Who would dare to stand on the city wall and face Zhao Hui's fire suppression?

"Why?"

"Why does Zhao Hui have such a thing?" Cao Cao Nannan said.
