Zhou Mo's feet were on the ground, and there were no accidents, his eyes adjusted to the darkness in the cave, and he saw Chu Yi standing not far in front of him, and in front of Chu Yi was a dark passage. The passage of the pen and the fun www.biquge.info was silent, and there was no human figure.

"This-" Zhou Mo followed Chu Yi's gaze and looked at both sides of the passage, the traces on the mountain wall were very rough, it looked like someone had cut it out, and it looked very new, obviously this passage had not been dug for long, if you want to dig up the mountain wall, Zhou Mo can also do it with the tools at hand, but this passage, the length that can be seen in front of you is more than 100 meters, which is definitely a lot of work.

Even if it was Chu Yi, don't look at the ease with him cutting the stone before, but to dig such a passage, he would have to be tired, and it would not be possible to complete it in a day or two.

"It's unbelievable, they actually built such a long passage here, where does this lead?" Chu Yi said in a low voice.

"With their strength, there is no need to hide underground local rats, it is impossible to have masochistic tendencies to live in caves. Zhou Mo said in a low voice, "Could it be that this leads to a certain ancient powerful cave?"

"That's the only explanation, otherwise I really can't figure it out. Chu Yi said, "Let's go?"

"Let's go!" Zhou Mo nodded, and the measuring ruler appeared in his hand silently, using the ruler as a sword, and together with Chu Yi, he cautiously stepped on the passage.

Zhou Mo and the others were ready to respond to attacks at any time, but until they walked through the entire passage, there was no attack, and that passage was simply an ordinary passage, with no organs, no formations, and not even a simple warning, except that the passage was particularly long, there was nothing different.

Walking through the passage that was two or three miles long, Zhou Mo and Chu Yi felt that they had come to the belly of the mountain, there was no light here for a long time, the surroundings were pitch black, Zhou Mo and Chu Yi were holding a cold light, the light could only cover the distance of two or three steps around the body, silent, dark, cold, as if it were hell, if the two of them were not ordinary people, they were afraid that they would collapse.

"Stop!" Chu Yi suddenly shouted in a low voice, making a stop movement, without his reminder, Zhou Mo had already stopped, not because there was an enemy in front, but in front, there was no road!

Zhou Mo stretched the cold light forward, and with the help of the faint light, he saw that a big black pit appeared one step ahead! It may not be appropriate to say that the big pit is, because the mountain walls on both sides have also disappeared, and one step away, there is an empty space, and the space is not on the ground or the sky, and it is impossible to see how big it is.

"What's the situation??" Zhou Mo was stunned, if you want to say that the mountain road is artificially opened, then this space, the possibility of artificially excavated is too small, although it is not clear how big this space is, but Zhou Mo can't feel the boundaries of this space at all, how can manpower do it in such a large space.

"It's not a cave, there should be water in the cave, there is no sound of water here. Chu Yi said, he took out a cold light from his backpack again, bent it a few times, the light lit up, he raised his arm, and threw the cold light forward, he had already come here, Chu Yi was not afraid of alarming the other party at all, if the other party showed up, he would not be able to ask for it.

The cold light light crossed an arc in the air, illuminating the route it passed, Zhou Mo and Chu Yi stared at it without blinking, this space was bigger than they imagined, the cold light flew out dozens of meters and did not touch the opposite mountain wall, but began to fall, until the light disappeared in front of the eyes of the two of them, it still did not fall to the bottom of the space, the two listened with their ears sideways for a long time, and the sound of the cold light landing still did not come.

"Bottomless pit?" Zhou Mo frowned, he didn't know how deep it was, he didn't know how wide it was, the other party obviously entered here, where did they go now?

"It's weird here, let's go out first, bring all the gear and come back. Chu Yi pondered for a moment and said, in this situation, this is also the only way.

More than half an hour later, Zhou Mo and Chu Yi returned to the edge of the mountain's belly space again, this time everyone in the ability group, including Lin Xiaochuan, followed in, there was no danger in this passage, so naturally there was no need for them to hide behind.

"Bang Bang-" The equipment carried by the people in the ability group was still very complete, and several bright flashlights shot out and shot directly into the space, and then a small drone flew up.

"I didn't expect to have this kind of benefit from liking aerial photography. Chu Yi exclaimed, this drone is not combat equipment, but a member of the ability group to bring it with him purely for aerial photography, but he didn't expect it to play a role here.

"I didn't expect that either. The young man named Zeng Qiwen, who controlled no one to pick up, said with a smile, there was a small screen in front of him, and the picture captured by the drone was fed back, and he did not control the drone up and down, but flew straight to the opposite side.

"Three thousand meters!" It didn't take long for Zeng Qiwen to shout, in the picture of the drone, a mountain wall appeared, he glanced at the distance, from them to the opposite mountain wall, across three thousand meters! This distance, unless you can fly with the sword, you can't fly by light power alone.

"Go down, see how deep it is!" Chu Yi commanded in a deep voice.

Zeng Qiwen responded, controlled the drone downward, and after a while, he raised his head and said, "No, it's already at the limit of drone control, and it can't reach the bottom." "His drone is specially made, and the control distance is farther than that of ordinary drones, but even so, there are limitations, which shows that the height of this mountain belly space has exceeded 10,000 meters!

"Is it possible to go straight to the interior of the earth here?" Lin Xiaochuan said.

"I think the space here may be different, even if it is inside Mount Tai, there should not be such a large space. Zhou Mo shook his head and said, "Pull the drone up, I seem to have seen something on the mountain wall just now." The latter sentence he said was with Zeng Qiwen.

Zeng Qiwen nodded, controlled the drone, and began to adjust the position angle according to Zhou Mo's instructions.

"Stop! Zhou Mo stared at the screen of the drone.

"It's—" The crowd held their breath, and they were all speechless in astonishment.

On the small screen of the drone, you can clearly see that there is a door on the mountain wall! It is a real door, not made of stone, but two transparent glass doors!

"Can anyone tell me why there are two glass doors here?" Lin Xiaochuan muttered. Where the glass door is located, there is no place to stand up and down, who can get two glass doors to install here? The back of the glass door is pitch black, and it is impossible to see what is behind the door.

"Boss, I'll go over and take a look. A female voice sounded, and then the girl with the ability to float jumped down, as if she was being held up by something, and stopped in the air.

"Don't be impulsive, come back!" Chu Yi shouted, he was worried about what danger would be in this space, and after the shout, the girl had already turned around, with a somewhat surprised expression on her face.
