After the props were broken, the entire guard tower was stained with a bright blue light.

An underground man ran to the front, raised his weapon and chopped down towards the guard tower. However, this knife didn't look like it had been cut on a wooden tower, it was more like it had been cut on granite. The guard tower itself did not leave a trace, but the knife in the hands of the underground man jumped out of a gap.

The underground man cut a few more times, the blade couldn't stand it, and it broke directly. After the underground man felt that he was broken, he froze in place and was hit as a target by Yu Shuang above.

"Hehe, this prop is really easy to use."

Does not destroy the city wall, the name of this prop. It acts on buildings and adds an hour of indestructibility to buildings within a certain range, and has 30% physical damage rebound and 20% magic damage rebound. But because the scope of action is only five square meters, Yu Tu judges it as a tasteless prop.

Indeed, the effect of this item is very powerful, if it can directly affect a large area of ​​the city wall, it can directly change a war.

However, even tasteless things have their place. Just like this small guard tower, it is completely within the range of not destroying the city wall, giving Yu Tu a stable output position.

With the help of Aiwen, Yu Tu quickly solved the enemy's shooter. After all, it was a surprise battle, and the number of shooters brought by the underground people was not much.

After the shooter is resolved, the two can comfortably resolve the enemies surrounding the sentry tower. No matter it is a warrior, a berserker or a knight, there is no qualified ranged skill. They can throw weapons up. But not to mention the problem of accurate head, the damage caused is too low, and it can be recovered without taking drugs. Moreover, after throwing the weapon up, they don't have a second spare.

The scene now is very funny. Yu Tu and two pets stood on the sentry tower and randomly cleaned out enemies that were far away. A large number of underground people surrounded them and smashed the sentry tower angrily. But the result of doing so was only to smash their weapons.

In this way, the two won a camp with no difficulty at all.

After confirming that the underground people in the camp were cleaned up, Yu Tu came to the middle of the camp alone. After speaking the order, a small tent appeared in the center of the camp.

There is only one stone platform in the tent with a large number of symbols carved on it. Yu Tu, who has seen the defense of the Koster city wall, is very clear that this is the starter of a magic circle.

There was no difficulty in the operation, and after five minutes, the whole camp was completely new.

Yu Shuang found an open space and released the teleportation array. After the transfer array landed, it immediately unfolded, forming a common transfer platform.

After the transmission platform was unfolded, the transmission light immediately lit up. A twenty-person NPC team came out of the teleportation array. He nodded towards the two of them, and hurried to the defensive facilities of the camp.

Taking a look at the teleportation array that was still running, Yu Tu patted Yu Shuang.

"Let's go, we are no longer needed."

"Ah, oh. I received another teleportation array here, do you want to continue?"

"Go on, you can get points, why not continue?"

Clicking on the map, Yu Tu began to find the next target.

On the map, the area around the fourth camp has turned into green representing friendly forces. The safety of activities in this area has been greatly increased.

In addition to the fourth camp, two camps on the third line of defense were also taken down. But the three camps are far apart.

After studying the map, Yu Tu decided to move to the side. The position of the fourth camp is in the middle of the flank of the third line of defense. In terms of orientation, extending to the northwest can rebuild one-third of the third line of defense.

Moreover, heading to the northwest can stay away from the frontline camp in the other direction. Yu Tu always felt that the knife had seen a tyrant near the camp.

After choosing the direction, the two set off quickly. When we attacked the camp just now, we could clearly see that people in the ground were still moving supplies. As the camp on the third line of defense, the war resources are still very rich, and the underground people want to move it in a short while.

As long as you seize this opportunity, you can win the camp more easily.

"There are four camps on the route we chose. It is not ruled out that other people may do it in advance. If that happens, we will avoid it."

"What if there are people fighting in all four camps?"

"Then we will go directly to the camp of the second line of defense. It happens to advance from the very edge to the inside. However, the materials of the second line of defense should be removed, and their defense force must be stronger than the third line of defense, and it may not give us Enough opportunity."

"What are you afraid of? As long as we can occupy the outpost, we won't panic at all."

"Maybe." Yu Tu didn't tell Yu Shuang the shortcomings of not destroying the city wall. Yu Tu had considered determining this item before. No one can guarantee that you will not encounter such a thing in the future, will you?

Through the previous battles, Yu Tu has already seen a very serious shortcoming of not destroying the city wall. Moreover, for underground people, it is not difficult to take advantage of that shortcoming. On the way to the next base, Yu Tu has been thinking about the changes that should be made after his shortcomings are exploited.

Two of the four established camps are already under attack. The two Yu Tu took the remaining two camps in the same way. After clicking on the map, you can clearly see the new third line of defense.

With the previous lessons, this time there will be no chance for the underground people to surprise.

"Well, the front should be Camp 13 of the second line of defense. The configuration is really different."

Yu Shuang poked his head, breaking his fingers and said: "Three hunting captains, two elite shooters, six elite berserkers. Wow, there is also an underground captain boss. It feels like it's not the same as before."

Yu Tu looked at the environment of the camp, pointed to the two guard towers at the entrance and said, "Yu Shuang, you will jump to the guard tower on the left hand side later, don't expose yourself. Give me one that will not destroy the city wall."

"Why is it like this again? It was the same two times before, I can also fight."

"It must be so. It is not clear to explain now. Can you still believe me? This is very important to us."

"Well, after this time, I must give me an explanation."

"I will."

After making a decision, Yu Shuang used the flicker to jump over. Yu Tu jumped to another guard tower and launched an attack. Reduced the possibility of residual frost being found.

While Yu Tu launched an attack, he used the non-destroying city wall. The underground people who came to attack were slumped again.

Yu Tu seized the opportunity to clean up the enemy's shooter. Especially those two elite shooters, Yu Tu and Ai Wen focused on taking care of them.

Yu Shuang hid away, watching the battle for a long time without any accidents, and sang freely. At this time, an accident happened.

Standing in the underground crowd, the boss underground captain roared and said some weird language.

The underground people standing at the bottom of the sentry tower were shocked, then dropped their weapons and started digging the ground frantically with their claws.

Yu Tu, standing on the sentry tower, was not surprised. This is the disadvantage of not destroying the city wall. Although it can protect buildings, buildings with weak foundations like sentry towers can easily collapse due to the shaking of their foundations. Even if it will not be destroyed because of the effect of not destroying the city wall, it is still possible to collapse.

"Aven, ready to withdraw."
