Tiannan City, more than ten meters high, is extremely strong, and a strong attack will inevitably cause heavy losses.

Zhou Yu came up with a way to do this.

These days, in order to build a military camp, a lot of mud has been cleared, and it is almost piled up into a mountain.

When thinking about how to capture Tiannan City, Zhou Yu thought of these silts.

Drying the silt is the soil, and piling up the silt from Nanshui Lake under Tiannan City can create a way conducive to attacking.

So, Zhou Yu waved his hand and ordered a large number of catapults to be built.

This delay was a week, and in order to prevent the mud from being dried, Zhou Yu also specially ordered someone to water and moisturize.

The letter of surrender was sent out for a week, but the Terrans did not move, and even the Lion Terrans thought that the Terrans were just here to be funny.

In a week, 5,000 catapults were built, and Zhou Yu immediately ordered the army to move.

Nanshuiguan is only fifty miles away from Tiannan City, which can be said to be very close.

The Arhat Imperial Guard took the lead, the Qilin spearmen and the Vermilion Bird archers were in the center, the cavalry walked on the two wings, and the rear of the army, the bear-people soldiers and the Green Goblin soldiers, carrying a cart of silt and 5,000 catapults, slowly moved forward.

The army of 600,000 people, who was close to Tiannan City with an ordinary cover, was discovered by the defenders of the Lion Tribe, and suddenly, the Lion Race entered a state of readiness.

The Northern Army has 500,000 ordinary soldiers, 100,000 Guards Legion, and 100,000 Knight Legion, of which the Guards Legion are all epic-level troops, and in terms of quantity, they are completely worthy of the human race.

However, as the defender, at most tens of thousands of troops can be stationed on the city wall, and in the face of hundreds of thousands of troops, the momentum is undoubtedly weaker.

The improvised trebuchet has a range of 1,200 meters, which has to be praised, all kinds of materials in this world are much better than those on earth.

The Luohan Imperial Guard stopped at 500 meters from Tiannan City, set up a shield as a defensive formation, the Qilin spearmen guarded the catapult to the designated position, and the Vermilion Bird Archers were also ready to prevent the enemy's surprise attack.

A cart of silt was pushed to the front of the catapult, and the surface of the silt installed in a wooden basin was dried in the sun, and a soldier buckled the silt in the wooden basin upside down on the catapult's catapult bucket.

"Put! ——”

With the order of the commander, the dense silt covered the city of Tiannan.

On Tiannan City, a group of lion soldiers hurriedly raised their shields for defense, and Watsendeck knew the power of the Terran archers, so he specially ordered people to make a batch of shields.

However, the lion-man soldiers waited for a long time, and they did not feel anything fall on the shield, but the walls trembled.

"They, this is, the distance is not calculated accurately?" Ab said with some hesitation.

Watsondecker frowned and didn't speak.

At this time, rounds of silt shells, either bombarded the city wall or bombarded under the city wall, and after a while, they piled up on a considerable scale.

After more than 20 rounds of shooting, Zhou Yu immediately ordered the catapult to retreat three meters and continue shooting.

In this way, in the bewilderment of the lion people, the human race is like a fool, taking care of its own projectiles, hitting farther and farther.

"What are the Terrans doing?" Andre also said with a strange face.

"Look at the city wall, the human race doesn't want to use this thin mud to fill in a path under Tiannan City, right?" Akava grabbed the wooden shield from the hand of one of the soldiers beside him, leaned under the wall, and immediately noticed it.

I saw that at this time, under Tiannan City, within a few meters, a layer of half-meter-thick silt had been piled up.

"How is that possible? How much dirt does it take, and how much manpower and material resources it takes! The gains outweigh the losses! Andrei immediately said in the negative.

"How could it not be? Don't forget, Nanshui Lake. Akava said, pointing into the distance.

When he said this, the other high-ranking members of the Lion Clan immediately remembered that Nanshui Lake had dried up, and there was a lot of silt at the bottom of the lake, so I was afraid that Tiannan City would be buried!

"This group of people, what is in the minds of the human race, this method can also be figured out!" Andrei couldn't help but curse.

"They must be stopped, for if they continue like this, our people will lose the benefit of the walls." Akava said, looking at Watsendeck.

"The Terran army is rigorous, and I can't see any chances." Watsendecker looked at the Terran army under the city, and without sending heavy troops, he couldn't force them back.

"Lord Governor, make a decision early, the city gate is blocked, and it will be difficult to kill it when the time comes!" Akava reminded Wassendeck.

"Leke, you take ten thousand knights, and you will meet them when you go out of the city." Watsondecker commanded Leke with his hand in his hand.

"Yes! Your Excellency the Governor! Leke answered, left the walls, and went to gather his troops and horses.

In the midst of the piercing sound, the city gate was opened, and a group of lion knights, stepping on the half-dry and half-thin silt fish, jumped out, just the work of the whole army, and another round of silt cannonballs arrived.

Suddenly, a group of lion-man knights were beaten in a mess, and although the mud cannonball was not powerful, it was really annoying.

"Kill!" Leke urged his fighting spirit, shook the mud off his body, and ordered an attack.

At a distance of five hundred meters, an effective charge could not be formed at all, and the lion knight collided with the Luohan Imperial Guard.

As soon as the two sides handed over, the lion knights found it very tragically that they couldn't shake the defense of the Arhat guards at all.

The five-hundred-pound fine iron giant shield can only be barely moved even if it is placed on the ground for the knight to lift, not to mention that their master is an Arhat imperial guard, and his strength can be compared to that of a great knight.

The catapults in the rear of the army did not panic because of the dispatch of the lion knights, and they still threw silt shells in an orderly manner.

Leke wanted to use his personal bravery to break out of the way, but was blocked by Zhou Tai.

After a battle, he didn't get a little cheap, and when he wanted to retreat, he was shot in the shoulder by Tai Shici with an arrow, if he hadn't dodged in time, this arrow should have hit him in the chest.

Frightened, Leke immediately ordered the withdrawal of the army, and after a short confrontation, nearly a thousand corpses of the lion knights were left, and under the bombardment of silt shells, the lion knights retreated to Tiannan City.

Leke, who had retreated, climbed the wall with an ugly face.

"Your Excellency the Doge." Coming to the city wall, Leke greeted Watsondeck with a fist and said nothing.

The situation on the battlefield just now, the high-ranking members of the lion clan on the city wall may have seen it more clearly than himself.

"How's the injury?" Watsendecker didn't mean to blame Leke, in fact, the reason why he let Leke go out of the city to face him was to let others see the strength of the Terrans.

"There is a powerful archer in the Terrans, if it weren't for my vigilance enough, I guess I wouldn't be able to come back." Leke pulled the arrow off his shoulder, threw it on the ground, and said hatefully.

As he spoke, he glanced into the Terran army, trying to find the Terran who was plotting against him.
