Chapter 1464 No One in the Outer City

Xu Tianyu entered the entrance of the cave only to find that there should be a passage left by some animal. It is not big, and he can barely move forward when lying on his stomach.

"Climb, climb."

It took more than half an hour before Xu Tianyu and the others came out from the entrance of the cave.

The place where they are is on the edge of the wall of the stubborn stone city, looking at the dilapidated buildings around them.

Xu Tianyu predicted that their location should be a poor slum.

"White devil, take someone to look around, be careful, don't be discovered by the devil."

"it is good."

Bai Mo left with seven players, and Xu Tianyu brought Yang Qin to a house that looked okay.

The room was full of cobwebs and dust, obviously it had been abandoned for a long time.

"Master, this is the house left by the residents of the previous stubborn stone city. Since it was occupied by the devil, no one has lived here."

"Um."

Xu Tianyu nodded, and then said.

"Yang Qin, do you know of any way to bring down those city walls?"

Just now Xu Tianyu looked at those city walls, and they were in a state of weathering. Obviously, the demons of the stubborn stone city did not repair the city walls.

If they can push down the walls of Stubborn Stone City, they will have the upper hand in this victory.

"Master, it is very difficult to push to the city wall. The thickness of the city wall of Obsidian Stone City is more than five meters. Although the surface is weathered, the inside is all hard obsidian. It is very difficult to destroy it. Even with the Spider Queen's self-destructing little spider cannot accomplish such a task.”

Xu Tianyu was not unlucky, but remembered the cave they had just entered.

"Yang Qin, from the entrance of the cave we came in just now, it can be seen that the underground of the city wall here is nothing more than mud. If we hollow out the underground of the city wall and bomb it with self-explosive spiders, is there a possibility of pushing it down? .”

This time Yang Qin was silent, obviously thinking about the possibility in Xu Tianyu's words.

"Master, I have to say that your idea is very good, but the stubborn stone city covers an area of ​​more than ten kilometers, and it is a very difficult task to hollow out the outer city walls, and there is noise in the excavation, so it is difficult to be sure that it will not be destroyed. The devil found out."

"Hee hee, as long as it's feasible, there's plenty of time."

Xu Tianyu smiled, he hadn't forgotten that he also had the black-backed pangolin that he had successfully researched before.

Although the number is small, the ability to dig holes is definitely very powerful.

It only took two days to dig through the entire magic lake before.

Although the stubborn stone city is bigger than the magic lake, the black-backed pangolin can definitely complete the task in five days.

Thinking of a way, Xu Tianyu immediately contacted Huang Jiajie, because after digging the hole, the black-backed pangolin was useless.

So Xu Tianyu took the black-backed pangolin back to Tianyu City to raise it, but he didn't expect that it was time for them to show their talents.

Huang Jiajie replied quickly, and it is estimated that within two days, the black-backed pangolin will be sent outside the stubborn stone city.

After Xu Tianyu ordered the players still on the river to respond, he prepared to explore the Stone City again.

Xu Tianyu shuttled around the room, but obviously the effect was not very good, and he didn't find anything.

At this time, the White Devils also came back.

"Tianyu, we groped around in the stubborn stone city and found that the whole stubborn stone city is divided into inner city and outer city. The inner city wall is only five meters high and not very thick. All the demons live in the inner city. "
