Xu Huang was by the Yushui River and sent people to observe Cao Cao and Sun Ce for five days, but found no abnormalities.

Cao Cao and Sun Ce in the city did not do anything, but had already started to set up defenses.

The news that Xu Huang appeared on the Yushui shore also spread to Yulin County five days ago.

It would be abnormal if Cao Cao and Sun Ce were indifferent.

As for all their mobilization and preparations now, it seems normal to Xu Huang.

It is impossible to see that Shi Xie showed signs of joining forces with Cao Cao and Sun Ce.

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

Then Shi Yi immediately came to see Xu Huang with Shi Xie's handwritten letter in his hand.

Xu Huang said with a cold face: "The prefect of the sages, I had agreed to have an army of 40,000, but why did only 30,000 come?"

"Report to the governor, Jiaozhou has few troops. After I went back to report to the governor, the governor said that he could only send 30,000 troops to cooperate with the governor. This is the clerk of the governor to the governor." Shi Yi took out his own written letter and handed it to Xu Huang.

Xu Huang took it and first glanced at the hot paint on the envelope, but there was no trace of being taken apart.

Then he tore open the envelope.

Shi Xie only wrote two or three hundred words, and Xu Huang finished reading it quickly.

Then he put the letter aside, looked at Shi Yi, and said, "Is this what Shi Xie means?"

"Return to the governor, I don't know what the provincial governor said in his letter." Shi Yi said.

He has never opened this letter.

But before he came, would Shi Xie not tell him?

Xu Huang found it difficult 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 also point a few words.

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

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

Xu Huang thought about it, but still put away the letter and did not show it to Shi Yi.

The content of the letter is very simple, mainly explaining the situation in Jiaozhou. There are many sinners sent to Jiaozhou now, and he dare not mobilize all the troops to Xu Huang.

Now we can only send 30,000 people to cooperate with Xu Huang. In addition, we need to be on standby at any time and be ready to suppress the rebellious prisoners.

Of course, this secret letter also mentioned Shi Yi.

Shi Xie hopes that Xu Huang will be able to use 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, is it because Shi Xie really didn't talk to Shi Yi, or Shi Yi pretended not to know, and had ulterior motives.

I couldn't figure it out, so Xu Huang dared to use Shi Yi with confidence.

We must even be careful about 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 have 10,000 people in their hands, Zhou Yu has already produced a lot of gunpowder over the past period of time.

Now I am facing Xu Huang, not Zhao Hui's main force, so Sun Ce and Cao Cao are still confident that they can defend Yulin County.

At most, they use gunpowder to bombard, and they have the advantage of city walls. Not only can the gunpowder thrown out be farther, but they can also find covers easily.

During this period, all the soldiers in their hands had been exposed to gunpowder and were used to the loud noises made when gunpowder exploded.

As long as you don’t directly meet 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 is no difference for them if they retreat a little.

However, Zhou Yu wanted to fight Xu Huang.

In the past five days, in addition to rushing to create gunpowder, Zhou Yu was also thinking about his plan to deal with Xu Huang.

He was wondering whether gunpowder could continue to be improved, whether there were more effective methods, whether there were other methods to use, and whether it could exert greater power.

After joining Shi Yi, Xu Huang led an army of 80,000 to set out towards Yulin County City.

From the edge of the Yushui River, you can reach it in just one day.

When we set off in the morning, Xu Huang appeared outside the city at dusk.

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 on the city walls, like turrets.

When the spy reported before, it had not appeared.

Now he led a large army to arrive, it was obvious that Zhou Yu had just installed it on the city wall.

These things have been created before.

Xu Huang held the telescope and observed it carefully.

Then he began to send people to approach.

When there were two hundred steps away from the city gate, the catapults on the city wall fired gunpowder.

Clay pots fell from the air and then exploded, turning into balls of fire, and pieces of soil on the ground flew high.

Then, Xu Huang immediately let the moving forward retreat immediately.

This is just to try out the attack distance between Sun Ce and Cao Cao and others.

Although Zhou Yu only launched an attack when the Zhao army was two hundred steps away from the city gate.

But Xu Huang knew that this did not mean the farthest attack distance between Zhou Yu and the others.

It was just because of this distance that Zhou Yu and the others felt the threat, and then they started to take action first.

Xu Huang calculated that the parabola of the pottery pot in the palace just now could not accurately calculate the maximum attack distance of these catapults.

But it should be eight hundred steps away.

In order to ensure safety, Xu Huang led the army and retreated one mile, two miles away from the city wall, which allowed people to set up camp.

The distance between two miles is basically certain that the catapults on the city wall cannot attack the camp.

On the city wall, Zhou Yu felt a pity as he watched Xu Huang lead the army to retreat.

It would have been great if he didn't attack just now, but unexpectedly, the attack within 200 steps still made Xu Huang alert.

If Xu Huang really dares to set up camp within one mile, Zhou Yu would have all the 80,000 people in Xu Huang and Shi Yi's hands tonight.

I had originally thought of hiding the catapult cart on the city wall, but Zhou Yu also considered that hiding it would also make Xu Huang alert.

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

However, Xu Huang was so careful that he was in line with Zhao Hui and did not give him any chance.

Although I just tried it out and threw more than a dozen pots of pots, it was enough to shock the first time I saw Tae Yi.

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

"Governor Xu, how many of this kind of gunpowder will be in Sun Ce and Cao Cao's hands?"

Although I have heard of it before, I have never seen it after all.

This time, Shi Yi immediately understood when he saw the gunpowder explosion with his own eyes.

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

With the power of this gunpowder, even if he pulls all the troops in Jiaozhou, he still can't beat Cao Cao and Sun Ce.

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