According to Cheng Sikong's experience, the vault will not exist alone, it must be connected with some buildings, although the appearance of the building cannot be seen on the surface, but if you explore backwards from the underground vault, you may be able to find some other clues.

Of course, this "clue" has automatically equated with "treasure" in Cheng Sikongdi's heart.

Cheng Sikong thought that he was not a person who ate white food, but now that there is no trace of human activity on the earth, even if he wants to pay some compensation, he doesn't know who to give it to.

In that case, don't blame him for being greedy.

It is very difficult to transport such heavy gold bars and gems out of the narrow ground cracks, and the ground forces need to expand the cracks to a size that can accommodate the passage of load-bearing robots, but this project is very time-consuming, Cheng Sikong did not forget that the purpose of their trip was to find the first generation of muses, and everyone could not stay here for a long time, so he left Duan Chengtian here to direct the transportation, and the rest of the people continued to advance deep underground.

Through Kuang Jiaping's perception, there are indeed more than these two rooms in this underground vault, they found a door to other rooms in the room where the diamond box is stored, due to the age of the door lock has long been off power and rusty, Shu Yungui used the "force has a thousand jun" to pull lightly, the original electric gate made a sharp "squeak" sound, revealing the mystery of the ancient earth civilization ruins to them.

Walking forward, everyone is still in the dark and cold man-made building, Kuang Jiaping and Shu Yungui are holding searchlights, you can see that this is a straight corridor, because the air inside the dust has not circulated for many years, and it is filled with the smell of decay, everyone has to open the isolation mask on the protective clothing to filter these harmful gases to the human body.

Tang Yue walked in the middle of the crowd, because his pants were half torn, so half of his legs were exposed, he was shivering with cold at this time, he rubbed his frozen thighs, and was about to change into the newly sent combat uniform sent by the ground troops, and looked down at the light of the searchlight, and the action of wearing pants stopped immediately.

Jesus, who was walking beside him, sensed that something was wrong with him, and as he looked ahead, the searchlight was shining straight ahead, and there was only an upward staircase in front of him, except for the closed doors on either side of the corridor.

It was the most primitive reinforced concrete pouring step on the ancient earth, without any floor tiles, only retaining the most primitive appearance of cement, with about thirteen or four steps on the first floor, and there were even some traces of wear and tear on the edges due to overuse.

It was just an ordinary ladder that could no longer be ordinary, just when Jesus followed Tang Yue's gaze and looked up and down the staircase, Shu Yungui, who was walking in the forefront, had already walked up with a searchlight, and the light shone obliquely from his hand upwards, if you ignore the lighting tools in his hand, this scene is like a bright sky light falling from the sky to illuminate the underground world, and the strange familiarity made Tang Yue sit on the ground.

"Hey! What's wrong?!"

Jesus hurriedly supported him, and everyone looked back when they heard the voice, and even Shu Yungui on the stairs turned his head sideways, but it was this simple and normal action that frightened Tang Yue to ignore the coldness on the ground and suddenly move back a few steps.

Seeing his frightened appearance, Lu Ting snatched the searchlight and stepped forward to open his eyelids, Tang Yue's pupils were still dilated under the strong light, which showed that his spirit was highly tense.

"His spirit should have been stimulated in some way, the medical anomaly ability didn't work for him, take an injection and send it up, he is not suitable to move forward in this condition now."

After that, some members of the field medical regiment put down their backpacks and began to look for tranquilizers, but at this time, Shu Yungui came down from the stairs, squeezed through the crowd and came to Tang Yue's side, called his name a few times, and sure enough, he couldn't hear any answer.

Tang Yue's whole body was trembling, and his eyes kept staring at the building in front of him, but everyone couldn't see any clues from his sight.

Faced with this situation, Shu Yungui made a decisive move, he pressed one hand on Tang Yue's eyebrows, and the spiritual mutation ability "Refreshing People's Mind" from Cheng Jing slowly unfolded, in order to let Tang Yue calm down quickly, Shu Yungui used the branch ability "Tranquility" of "Refreshing People's Mind", with it

With a gentle force pouring into his body, Tang Yue soon stopped trembling and fell into Jesus' arms.

Lu Ting examined him again, the dilation of the pupils had disappeared, the pupils had returned to their normal size, and the lights shone on him and he knew that he had closed his eyes, indicating that he had resumed his normal response to external stimuli.

Tang Yue gasped for breath, he felt as if he had been stunned just now, and his consciousness was not in him at all.

"Take a deep breath, relax, we're all there, tell us what you see, don't be afraid."

Shu Yungui glanced at Gu Xingtang slightly under the cover of darkness, if the information provided by Gu Xingtang was not wrong, then the ancient earth should have become the territory of the muse now, and Tang Yue's ability was mainly concentrated in the online world, it can be said that in addition to Gu Xingtang, Tang Yue was the muse's biggest opponent, if the muse wanted to do something to him, from the moment he fell off the cliff to the current trance, it was probably the muse's ghost.

Tang Yue slowed down for a while, finally sat up straight and wiped the sweat on his face, his breath was unsteady, and he said in a trembling voice, "I...... I saw you just going up the stairs."

Hearing him say this, everyone looked back at the staircase again, it was just a simple staircase that could not be simpler and more normal, let alone on the ancient earth, even in the Hope Star Field, and even the Ninth Star and the Butterfly Nebula, as long as there were human beings, there would definitely be such a staircase.

And there are still a lot of such stairs, because this kind of staircase as a building structure no longer needs to be optimized, and people have been building this kind of staircase for thousands of years as a fire escape in various buildings.

"Maybe it's a sense of déjà vu, right? In the artificial intelligence control center of the Butterfly Nebula before, didn't we also walk through the stairs together? Are you confusing the two scenarios?"

Kwong asked, "It's normal for your head to be concussed when you fall, and your memory is temporarily confused."

"That's right, although I used my mutation ability to help you heal your trauma, there will be a period of confusion after the trauma of the memory neurons, and you will even imagine many things that don't exist."

As an authoritative medical expert, Lu Ting's words have a very high degree of credibility, but Tang Yue touched the back of his head and said firmly: "No, it's not a memory disorder!"

He looked at Shu Yungui, and then looked at the stairs in the distance, although the searchlight did not shine in that direction at this time, and the stairs were hidden in the darkness, and he couldn't see any clues, but he still insisted: "In the artificial intelligence control center of the Butterfly Nebula, we are going down, but in my memory you are going up, I can't confuse the direction!"

"I didn't immediately fall unconscious after I fell, I saw a group of people enter this underground vault, but there was no gold or gems in the vault at all, and they took me with them, through two gates, to this corridor."

Shu Yungui looked back at the path they had walked on, from the house where the gold bars were stored to the corridor where they were now, according to the normal order, they did have to pass through two gates, but one of them was smashed down by Zhu Xinyue along with the door and the wall, so they looked as if they hadn't walked through the first gate.

"The group was wearing white shirts and black pants, they had yellow skin, black hair, and ...... faces."

Tang Yue suddenly shuddered again, and said in a panic: "There are only skeletons on the face, and the skeleton's mouth is very sharp and long, even sharper than the mouth of the big fat dragon......

"White shirts? Skull face? A long, pointed beak?"

Shu Yungui looked suspicious: "It seems that none of these things you said can be combined with a person, are you sure that is not your hallucination? If they keep taking you with them, why do you end up in the vault?"

"I don't know, my memory is only until the person turned around, because I was so scared to see your face, I woke up."

Lu Ting on the side touched his chin and said, "According to what you said, even if part of this memory is true, the last scene you saw Shu Yungui must be a memory disorder."

"First, he never left our sight from beginning to end, and it is even more impossible for him to appear on the stairs through the two gates, you should have seen the man with the skeleton and bird's beak turn his head, and then happened to be woken up by Shu Yungui, the two images overlapped in my mind, and Shu Yungui's face coincided with the face of the mysterious man."

"This ...... I don't know about this, but the scene I saw just now when Brother Shu stood on the stairs and looked up with a lamp was too similar to the scene I saw......

Tang Yue pressed his heart with palpitations, although the group of people who led him didn't do anything to him, he just felt that the scene was terrifying, and there was an indescribable grotesque feeling.

According to Lu Ting's explanation, the last Shu Yungui that appeared in his memory came from overlapping sights, so what were those skeletal and bird-beaked men he saw earlier? Did they ever exist in this world? If so, what have they done in this underworld? Why did it appear in the mind of Tang Yue, a teenager from an alien planet?

Everyone at the scene had questions in their hearts, Shu Yungui and Cheng Sikong glanced at each other and decided to move on, they came here to explore the secrets of the ancient earth, and it was impossible to terminate the mission because of a strange dream of unknown origin.

This time, everyone went up the stairs together, and there were some yellowed old newspapers scattered on the steps, which should have fallen from the wall, Shu Yungui glanced down, the date of the newspaper was the most serious disaster in the era of natural disasters on the ancient earth, and the newspapers were full of distress messages from all over the world, but I don't know if those people were saved at the beginning.

He looked up at the wall, where there was originally an information board from which the newspaper fell, and in the information column there were also some information about rescue teams from all over the world, and most importantly, in the most conspicuous place, a sentence written in red paint—

"Did humans defeat the earth, or did the earth defeat humanity???

Finally, there are three huge bright red question marks, which are enough to see how strong the question in the heart of the person who wrote this sentence is, even today, thousands of years later, his question is still shocking, so that everyone has to reflect on whether it is man who has defeated the earth, or the earth who has defeated man?
