Outside Xilong City.

"Sir, it seems they have been prepared."

The general who was on the vanguard was observing the deployment of Xilong City. When he saw Zheng Yuanyun personally coming to the front line to supervise the battle, he hurriedly bowed and saluted.

Zheng Yuanyun hummed, not surprised by Xilongcheng's reaction.

Although his army shouted slogans of surrender without killing as soon as they arrived at the city, it was obvious that the opponent was unmoved.

He raised his head and looked at the head of Xilong City from a distance. It was too far away to see clearly, but Zheng Yuanyun believed that the defenders stationed at the head of the city would be frightened when they saw such a huge enemy force coming.

My hands and feet are weak.

But after all, they still did not surrender and wanted to resist pointlessly.

Zheng Yuanyun knew the reason very well.

When he knew that Ouyang Lixing led his troops out of Dongping City but did not come to Ketan City to attack him, he had already noticed the opponent's plan.

Unfortunately, this was an obvious plan. Even if he noticed it, he could only attack the city one by one as the other party hoped. There was no other way.

So this is the reason why Zheng Yuanyun decisively sent Xiao Du back to find reinforcements.

Xilong City is surrounded by water on three sides, and only the city gate in the middle is passable. However, before Zheng Yuanyun arrived, the commander-in-chief of Xilong City, who had received Ouyang Lixing's instructions, ordered the city's protective bridge to be cut off, and the city gate with a radius of two meters was cut off.

All ships within thirty miles were burned, and even a dense forest not far from Xilong City was destroyed.

Not only were Zheng Yuanyun not allowed to leave any boats, but he was not even prepared to leave any wood for him. This made it clear that Zheng Yuanyun was not allowed to cross the river.

"You want to stop me just like that?"

Zheng Yuanyun looked at all the arrangements made in Xilong City with a sneer on his face.

He had already studied the topography of Xilong City before coming here, and knew that it was surrounded by water on three sides, and the river was wide and long. If he didn't want to cross the river and took a long way around...

He would probably go all the way around to the border of Fengqi Province, where the river would begin to narrow and there would be a way for the army to cross the river without relying on boats.

If that were the case, the day lily would be cold.

Zheng Yuanyun didn't need to say whether he could attack the city or not, he just stayed in Ketan City and waited for reinforcements.

But if that really happens, once Ouyang Lixing has made arrangements and the reinforcements from the Zhu Yan Empire arrive, he may not be able to do it even if he does bring reinforcements.

So, we still have to attack!

As for the attack method, he already had an idea on the way here. When he saw the situation, it was just as he expected. He was not anxious or annoyed. He only ordered with a sneer: "Send the order and let the catapult be ready!

"

"Stones?"

The vanguard general's name was He Yu. He was stunned when he heard this and said in disbelief: "Sir, the distance of the moat..."

Just by visual inspection, we can tell that the width of the moat is more than two hundred steps, which means that even if they push the catapult directly to the river and launch it, the huge falling rocks will not be able to attack the city wall.

Even if we attack it, what's the use?

The bridge was destroyed and there were no ships anywhere. Even if a big hole was blown out of the city wall without the troops to repair it, what would it be of use?

Mr. Zheng should understand this truth better than himself, so what is the purpose of his move?

He Yu couldn't understand. Although he immediately followed Zheng Yuanyun's instructions to mobilize the catapult troops at the rear of the camp, this doubt was clearly written on his face.

"Who said I was going to blow up the city wall?"

Zheng Yuanyun glanced at him and said coldly: "Don't they think we can't cross the river without boats?"

"Then let them take a good look at how our Qingyang Empire builds roads!"

"Repair... repair the road?"

He Yu opened his mouth wide and blinked twice, finally understanding what Zheng Yuanyun meant.

The catapult troops were mobilized. Their purpose was not to attack Xilong City, but to use a large number of stones to fill up the fast-flowing river under the city wall and create a road out!

He Yu had never even thought about this idea, but Zheng Yuanyun seemed to have already made up his mind and had a countermeasure without even the slightest hesitation.

As expected of Mr. Zheng!

He Yu thought with great admiration.

Zheng Yuanyun's method seems stupid, but it is not.

In order to attack the province of Nantes this time, Zheng Yuanyun had made complete preparations when he was in Bo'an City, including a large number of logistical troops and a large number of catapult troops.

The total number of catapults they brought to the front line has reached an exaggerated 1,000. This round of volley will hit more than 1,000 huge catapults.

When preparing for the outskirts of Ketan City, Zheng Yuanyun had already ordered people to focus on collecting suitable stones. Even a large amount of gravel was wrapped in animal skins and stored a large amount of ammunition.

According to the amount of ammunition they transported...

He Yu made a rough estimate, not to mention filling in the river, but even using these stones to build a city wall would be enough.

How dare those guys be so stubborn and insist on letting us do it ourselves, so good...

A sly smile appeared on the corner of He Yu's mouth. When the city is defeated, I will tell you to take a good look at what will happen if you stubbornly resist!

"I see……"

In Ketan City, what Zhang Hualin heard through risking his life to get closer, Chen Ze nodded clearly.

"Isn't this just throwing a whip to cut off the current?"

He shook his head and smiled, "Sure enough, it's good to have more people!"

Xilong City has achieved this level of city defense and thought of making full use of the moat defense method. Unfortunately, Zheng Yuanyun was not willing to give them even this opportunity. He had already planned to use catapult ammunition to attack the city.

Strategies for filling the moat.

This method is clunky, but effective.

After all, although the moat is very wide, the water in the river is not too fast. Zheng Yuanyun dropped very heavy boulders. As long as there are enough of them, he can really fill a passage to the opponent's city gate.

of.

But this is fine, at least the goal is achieved.

Want to build a road?

It sounds simple, but the time consumption is indispensable. It more or less achieved the goal of Chen Ze and Ouyang's strict reservation, holding back Zheng Yuanyun and preventing him from easily taking Xilong City.

Furthermore, the temporary construction of the road has limited traffic capacity after all, and it is impossible for Zheng Yuanyun's soldiers to charge bravely like a smooth plain. The number of soldiers who can attack Xilong City within a unit of time will be sharply reduced.

As a result, Zheng Yuanyun had to lose more soldiers to capture Xilong City. No matter how much more soldiers were lost, this would be a loss of troops that was beneficial to the Zhu Yan Empire.
