The equipment brought by the group was very complete, and when the bright flashlight shone into the cave, the cave immediately lit up as day.

This is an underground culvert that humans have never set foot in, and there are no traces of human excavation in the cave walls, because there is wind in it, so there is oxygen, and the humidity is not so great.

Guan Yu was at the front, Ye Yurou pulled the corner of his clothes, then Leng Ruobing, Chen Zhu, Wang Zhu, Zhu Qingfeng, Hong Xing, and finally Nicole.

Guan Yu has divine thoughts, so he knows the culverts that extend in all directions, and he travels down very quickly.

Naturally, no one spoke along the way, and they all walked quietly, but as they walked, they also noticed that the downward slope seemed to be getting bigger and bigger, and they should have gone deeper into the ground.

And just as everyone was walking, suddenly Guan Yu, who was walking in front, stopped.

Everyone was stunned, and then they saw Guan Yu squatting down and shining a flashlight on the ground!

"It's footprints, human shoe prints. The crowd exclaimed, there had been someone entering!

Guan Yu used a flashlight to shine in another direction, the footprints were not one person's, they were a lot of people's, it looked very messy, the direction was in front of their left, that is to say, the people with these footprints entered the culvert from another direction, or rather, this culvert that extends in all directions underground, not only an entrance by the pool.

"They walked towards the culvert. Guan Yu took another look in the direction of the shoe print, and then strode over.

Following the footprints, the group walked for another two hours before stopping, and at the same time everyone also found that there was no fork in the road here, only this one continued to go down, and the footprints continued to move forward.

"What can now be confirmed is that it is not that no one has entered, there has been at least a team of more than five people here, including a woman, and there are cigarette butts, wine bottle caps and other household garbage along the way. ”

"I mean, are we going to move on, because I feel like it's not safe up ahead. Guan Yu looked back at the other companions, here, it seems that there is some kind of secret hidden, and if you follow the shoe prints, you will definitely find this secret, and there is definitely danger ahead.

"Boss, it's all here, how can there be any reason not to continue. The boys in the back said loudly.

"Well, be careful, Nicole, and keep an eye on your back, as there are no footprints of a large beast here, but just in case. Guan Yu instructed.

"Yes. Nicole nodded.

Guan Yu took a deep breath, and then continued to go down, continuing forward.

The passage seemed to have no end, it was long and deep, and what everyone could confirm was that the wind tunnels in front of it may not have been dug by humans, but the passage that went all the way down was definitely carved out by hand.

However, there seems to be no record of this in human history, so everyone is nervous and excited.

"Huh~" After walking for six or seven hours, Guan Yu stopped again and took a deep breath, because in his divine thoughts, he finally saw the end, and there was a turn in front of him, and fifty meters away, there was a stone gate.

In this underground cave, there is a stone gate!

In terms of time and slope, there is a distance of seven or eight hundred meters from the ground here, right?

Seven or eight hundred meters, could it be a cave in ancient times or something? Otherwise, there is no way to explain it.

"Door ......" Finally, the others also saw the door, it was a huge stone door, the kind that opened up and down, from the outside, this stone door was definitely one meter thick, when it fell from above, if it was not a strong man, unless it was a person from the Jindan Realm, it could be broken!

The crowd ran over, and the footprints disappeared at the stone gate, apparently entering the inside.

At this time, Guan Yu's eyes looked at a rotating mechanism on the wall, which was a disc-shaped, button-like stone disk.

Guan Yu frowned, because his divine thoughts could not penetrate this stone gate, it was very strange and surprising to him, you know, since he had divine thoughts, he could wear everything, any underground or wall, he could penetrate.

But now, it was blocked by this stone gate.

There can only be two explanations for blocking his divine thoughts, one is that the thickness of the stone gate is more than a hundred meters, and he can't see through it at all.

The other is ...... Legendary formations.

Legend has it that there is a formation that blocks mental power.

"Everyone step back fifty meters, wait around the corner, Nicole stands in front of the defense, I'll open the door, if there is danger, you immediately turn around and flee, if there is no danger, you come again!"

Everyone has no objections, and the most powerful is Guan Yu, so he has the power to decide everything.

Everyone quickly retreated, and it was not until they retreated to the corner that they hid fifty meters away, and then Guan Yu held the stone plate tightly and turned it hard!

"Click~Click......click" The sound of the mechanism turning sounded, and the stone door slowly rose in the vibration, while Guan Yu retreated a few meters and shone under the crack of the door with a strong flashlight!

"Huh~" When the door rose to a certain height, Guan Yu saw a person, a soldier, and it seemed that he was also a woman!

Guan Yu was taken aback and rushed over in a hurry, because he thought of his mother.

"Whoosh~" As soon as he entered, Guan Yu immediately flipped the person over, and then saw that this female soldier was not his mother, but ...... But...... He knew this man!

That's right, he knows this person, because this is his mother's colleague, Aunt Xu!

Guan Yu's arms were a little shaky, his thinking was a little confused, his mother's memorial service was held collectively, and there seemed to be Aunt Xu inside!

"Aunt Xu!" Guan Yu closed her eyes, Aunt Xu was very thin, her whole person became skinny and bones, and she died at the door, so obviously she couldn't break through the stone door from the inside, and she starved to death!

"Mom......" Guan Yu suddenly shook his whole body at this time, Aunt Xu is here, so mother......

He screamed and ran inside!

Leng Ruobing and the others in the back had already run over, and after seeing this woman in military uniform, their faces were solemn!

Ye Yurou ran forward and chased Guan Yu.

However, this space is not large, and after Guan Yu ran in, everything inside was clear at a glance!

Sure enough, there were five people, four men and one woman, and these four men sat side by side, all in the same posture, their temples also had bullet holes, and the man on the far right was holding a small pistol in his hand!

They were trapped and died here, and in the end they ran out of oil and lamps, without any supplies, and they couldn't contact the outside world, and they couldn't get out, so they chose to commit suicide!

There was no cannibalism, and there was no mess, except for Aunt Xu, the other four of the five people walked peacefully! They chose to leave with dignity and dignity.

But why not have a mother!

Mother is with them, how could it not be? Also, what the hell is this place, why is it empty!

"Squeak ~ boom", at this moment, just after everyone walked into this stone room space, the stone door suddenly fell by itself, and the stone room was sealed again!

Everyone's faces changed dramatically......
