Xu Huang was on the edge of Yushui, and sent people to observe Cao Cao and Sun Ce for five days, but he didn't find anything abnormal.

Cao Cao Sun Ce in the city was not idle, but had already begun to arm.

The news of Xu Huang's appearance on the shore of Yushui also reached Yulin County five days ago.

If Cao Cao and Sun Ce were indifferent, it would be abnormal.

As for all their current transfers and preparations, in Xu Huang's opinion, they are all normal.

I can't see that Shi Xie has signs of joining forces with Cao Cao and Sun Ce.

On the fifth day, Shi Yi finally led an army of 30,000 and arrived at the edge of Yushui.

Then Shi Yi immediately carried Shi Xie's autograph letter and came to see Xu Huang.

Xu Huang said with a cold face: "Shi Taishou, I originally said that there were 40,000 troops, but how did I only come with 30,000?" ”

"Back to the history of the assassination, Jiaozhou's troops were already small, and after I went back to report to the state pastor, the state pastor said that he could only send 30,000 troops to cooperate with the adults. This is a document given by the state pastor to the history of the assassins. Shi Yi took out the autograph book and handed it to Xu Huang.

Xu Huang took it, and first glanced at the fire paint on the envelope, and there was no trace of it being opened.

Then he tore open the envelope.

Shi Xie also wrote two or three hundred words, and Xu Huang quickly read them.

Then he put the letter aside, looked at Shi Yi, and said, "This is what Shi Xie means?" ”

"Back to the history of the assassination, I don't know what the state pastoral letter said." Shiyi Road.

He really didn't open this letter.

But before he came, did Shixie talk to him?

Xu Huang found it hard to believe that Shi Yi would be completely unaware of the content of this letter.

Maybe Shi Xie didn't finish the book and told him, but at least he would have a few words.

"You really don't know?" Xu Huang said.

"I don't know." Shi Yi still shook his head.

Xu Huang thought about it, but still put away the letter and didn't show it to Shi Yi.

The content of the letter is very simple, the main thing is to explain the situation in Jiaozhou, now there are many sinners in Jiaozhou who have been assigned, and he does not dare to mobilize all the troops to Xu Huang.

Now only 30,000 people can be dispatched to cooperate with Xu Huang. The other is the need to be on standby, ready to suppress the rebellion.

Of course, Shi Yi is also mentioned in this secret letter.

Shi Xie hopes that Xu Huang will reuse Shi Yi well, and Shi Yi will definitely obey Xu Huang's orders.

That's why Xu Huang asked Shi Yi.

Xu Huang is not sure now, whether Shi Xie really didn't tell Shi Yi, or Shi Yi pretended not to know, and had other intentions.

I couldn't figure it out, where did Xu Huang dare to use Shiyi with confidence.

You even have to be careful to beware of Shi Yi and the 30,000 troops he brought.

Cao Cao and Sun Ce were still making various preparations in the city.

Although they only had 10,000 people in their hands, Zhou Yu had already made a lot of gunpowder during this time.

And now it is only Xu Huang who is facing it, and he is not the main force of Zhao Hui, so Sun Ce and Cao Cao are still confident that they can hold Yulin County.

At most, they could use gunpowder to bombard, and they had the advantage of walls, not only could they throw gunpowder farther, but they also made it easier to find cover.

During this time, all the soldiers in their hands had been exposed to gunpowder, and they were all accustomed to the loud sound of gunpowder exploding.

As long as he doesn't directly face Zhao Hui, Zhou Yu has confidence.

Otherwise, when Xu Huang arrived at the edge of Yushui, they should have withdrawn.

Anyway, they all retreated from Yangzhou to Jiaozhou, and there was no difference for them in retreating a little.

However, Zhou Yu wanted to fight with Xu Huang.

In the past five days, in addition to speeding up the manufacture of gunpowder, Zhou Yu was also thinking about a strategy to deal with Xu Huang.

He was wondering if gunpowder could continue to improve, if there was a more effective way, if there was any other way to use it, and if it could exert greater power.

After rendezvous with Shiyi, Xu Huang led an army totaling 80,000 and set off towards Yulin County.

From the edge of Yushui, along the official road, it will only take a day to arrive.

Set off in the morning, and at dusk, Xu Huang appeared outside the city.

It was more than a mile away from the city wall, but through the telescope in his hand, Xu Huang saw the catapults standing on the city wall.

Those who say they are catapults are actually fixed to the city walls, like turrets.

When the spies reported before, they hadn't shown up yet.

Now he arrived with a large army, apparently Zhou Yu had just installed it on the city wall.

These things have also been built before.

Xu Huang took the telescope and looked at it carefully.

Then he began to send men forward.

Two hundred paces from the city gate, the catapults on the city walls fired gunpowder.

Clay pots fell from the sky and exploded, turning into fireballs and clumps of dirt flying high on the ground.

Then, Xu Huang immediately let the advancing people retreat as soon as possible.

This is just to test the attack distance of Sun Ce and Cao Cao.

Although the Zhao army was two hundred paces away from the city gate, Zhou Yu launched an attack.

But Xu Huang knew that this was not the same as Zhou Yu's farthest attack distance.

It was only because of this distance that Zhou Yu and the others felt threatened, and then they made the first move.

Xu Huang calculated for a moment, and the parabola of the clay pot in the palace just now could not accurately calculate the farthest attack distance of these catapults.

But it should be eight hundred paces away.

In order to ensure safety, Xu Huang led the army and retreated another mile, two miles away from the city wall, so that people could set up camp.

At a distance of two miles, it is basically certain that those catapults on the city wall cannot attack the camp.

On the city wall, Zhou Yu watched Xu Huang lead the army to retreat, and felt very sorry in his heart.

It would be good if he didn't attack just now, but he didn't expect that the attack within two hundred steps still made Xu Huang vigilant.

If Xu Huang really dared to set up camp within one mile, Zhou Yu would be able to wipe out all the 80,000 people in the hands of Xu Huang and Shi Yi tonight.

Originally, he also thought about hiding the catapult on the city wall, but Zhou Yu also considered that hiding it would also make Xu Huang vigilant.

It's better to put it out for Xu Huang to see, and then make Xu Huang mistakenly think that their catapult has a very close range.

However, Xu Huang was so careful, in the same vein as Zhao Hui, he didn't give him a chance at all.

Although it was just a small test just now, throwing more than a dozen clay pots, it was enough to shock Shiyi's heart when he saw it for the first time.

When Xu Huang retreated to camp two miles away, Shi Yi followed Xu Huang and asked Xu Huang for advice.

"Xu Tingshi, how much of this gunpowder will Sun Ce Cao Cao have in his hands?"

I've heard of it before, but I haven't seen it after all.

Seeing the explosion of gunpowder with his own eyes this time, Shi Yi immediately understood in his heart.

Xu Huang asked them to cooperate, but he definitely did not put the hope of exterminating Cao Cao and Sun Ce on them.

With the power of this gunpowder, don't take the 30,000 people in his hands now, even if he pulls all the troops in Jiaozhou, he still can't beat Cao Cao and Sun Ce.

Fortunately, at that time, they did not directly attack Cao Cao and Sun Ce, otherwise they would have really capsized.

Thinking about it now, Shi Yi is still scared in his heart.
