Nangong Shi nodded: "you guessed right. There are indeed many pits in baikeng mountain range, which are countless in size. But there are more than 100 pits in large scale, so it is named baikeng mountain range."

"Who is so boring to dig so many holes?" Black heart nine asks curiously.

Nangong Shiyi looks speechless, who will be bored to dig a hole?!

"These pits are not dug by human beings, but formed naturally. These pits are also the main producing areas of lightning stones. We will go down to the pits to collect lightning stones.

Baikeng mountain is not only forbidden to fly, but also unable to use jade seal script. We have to go down to the bottom of the pit with rope, so the risk is still very high. You should be careful when you get there. "

Black heart nine corners of the eyes twitch, this is not the legend of the pit? Or that kind of pit!

There was no word on the way. On this day, people arrived at baikeng mountain.

Looking from the outside, baikeng mountain can't see any difference between baikeng mountain and other mountains. However, after entering the mountain, we found that the ground was covered with large and small pits.

These pits are deep and shallow. Some of them are covered with vegetation. If you step into the air carelessly, you will fall into them.

Fortunately, Xiao's deputy Zhang Yuan and others had a topographic map in their hands, so they took the people around the hard to find pits.

After a day's trek, they finally arrived at the first pit.

Yunchu nine looked at the huge Tiankeng, and was really shocked.

On that day, the pit was hundreds of feet deep. If someone was timid, he would not have the courage to look down.

The edge of the Tiankeng is covered with vegetation, and there are many vegetation below, but there are also many exposed places. It is estimated that those places are the origin of lightning stones.

Xiao Lianqiao and others are also the first to see such a pit. Their faces are full of fear. There is no road from top to bottom. Is it true that they are going down by ropes?

If the rope breaks in the middle of the way, or is attacked by a monster on the way, what's the life of it?!

"You can rest assured that the rope we use is made of ten thousand strands of tough hemp, which is extremely strong. Moreover, the vegetation in the selected place is relatively low, and there will be no high-level monsters hiding. As long as you move quickly, there will be no danger.

What's more, cultivation is full of danger. If you don't have this courage, you don't deserve to be students in the upper class of Shifang Academy. " Xiao Deputy palm courtyard cold voice says.

There was a look of shame on the faces of the people, but much of the fear had been dispelled.

Yunchu nine's eyes flashed. Xiao's vice-president didn't want to throw her to death?

It's really possible. After all, people miss and horses miss. When the time comes, a careless one will be prevaricated.

However, it is estimated that this is the first day, he will not be in such a hurry, so there is no need to worry about it.

What's more, even if he let go of the rope, she would still be able to save her life.

At this time, a lecturer has put down the rope, which is wrist thick enough and looks really tough.

The lecturer wound one end of the rope around a big tree and tried to say, "Xiao deputy head of the courtyard, OK."

"Lecturer pan and lecturer Qiu, you two stay on the top and guard the rope. Lecturer Yao and I will take them down." Xiao Deputy palm yard finish saying, take the lead to follow the rope to descend toward below.

For the sake of safety, when Xiao's deputy leader's courtyard descended to the bottom of the pit, all the people began to climb down the rope one after another.

When they got to the bottom of the pit, the excitement was hard to hide. Although the process was a bit breathtaking, it was really exciting.
