Zhou Tian looked around at the edge of the high-rise building, but the edge area was still out of reach, even if it was him, he couldn't see it clearly!

"Let's take a look around first, this can't be the only one strange here, and besides, the entrance to the cave we left can't be the only one we left when we left!" Zhou Tian said.

The four of them looked at the huge "Night Pearl" illuminated by the dungeon again, turned around and walked down from the tall building.

"We spread out, searched from different directions, and if we find anything, don't worry, and in an hour, we will come back here to meet!" Zhou Tian said.

The four nodded in understanding, and left in four directions.

Zhou Tian glanced back at Liao Yifei with some anxiety, and just as she also looked back, the two looked at each other, and she immediately turned around and walked quickly.

Zhou Tian exhaled and walked to the back of the tall building.

Behind the high-rise building, there is also a street, looking at the style of the buildings on both sides, he guessed that it should be a commercial street or something, and the first floor on both sides has wide facades, some are open, some are closed, and some are ......

Zhou Tian was suddenly attracted by a room!

It was a two-story building, with no fancy decorations, a simple rammed earth wooden frame structure, but the sliding door of the door was ajar, and the door was cut through the middle by a sharp weapon like a knife, half of which was broken, and it hung on the other half of the door.

This is the first time they have seen traces of human beings since they came in.

He slowly walked to the broken door, and with his hand, the whole door was easily pulled down from the door frame, and fell to the ground with a "bang", stirring up a puff of dust.

Zhou Tian hurriedly blocked his mouth and nose with his arm, and flashed twice with his hand.

Wait until the dust has cleared a lot, then raise your eyes and look inside.

The furnishings of the room were simple, with wooden tables and chairs in the middle, a straw rope on the wall, some clay pots piled on the right, and a door to the back on the left, with a straw curtain hanging.

Zhou Tian walked over, stretched out his hand and lifted the straw curtain, and the grass fell suddenly and fell to the ground into pieces.

Sunday: "......"

It seems that it is still necessary to be careful, it is better not to spoil anything here.

Thinking so, Zhou Tian walked in more carefully, and because there was no window inside, it was very dark, so he turned on the flashlight.

As soon as the flashlight was turned on, the scene inside was revealed.

This is a door leading to the upper and back doors, and the back should be a kitchen or something, and there is a low stove made of mud against the wall, which Zhou Tian thinks is quite similar, boxy, with a round hole in the middle.

There are wooden shelves next to them, and there are several pottery bowls and utensils that I don't know what to do.

Turning his head to look at the stairs up, Zhou Tian was a little hesitant, this staircase should not be broken by him again, and there was nothing surprising about the appearance of this room, so he wanted to turn around and leave.

However, at the moment when Zhou Tian turned around, he seemed to catch a glimpse of something flashing on the second floor out of the corner of his eye.

Without any further hesitation, Zhou Tian instantly activated the power of the origin, and jumped directly to the second floor on tiptoe.

The second floor should be a bedroom room, a total of two rooms, and the direction that I just glimpsed was on the left.

Zhou Tian walked lightly to the left, the room had no door, only a half-cut straw curtain, he bent down to look inside.

The tatami mat-like platform built above the ground with mud must be the bed.

Other than this, the room turned out to be empty, what was it that flashed by just now?

Zhou Tian looked inside carefully, and after looking at it for a while, he gave up, as if there was nothing.

Turning around and walking to the room on the right, Zhou Tian's feet were beaten.

Something flashed behind him out of the corner of his eye, so fast that he couldn't even see what it was on Sunday.

didn't have time to think about it, Zhou Tian raised his legs and chased after him, all the way out of the house to the street.

Zhou Tian looked back and forth, and there was nothing. Looking back at the room behind him, not only did he smile a little, this is obviously an empty city, how can there be any living creatures?

As for the marks on the door, they must have been left by the predecessors when they left!

Thinking of this, Zhou Tian continued to walk forward.

Gradually, Zhou Tian stepped out of the building and came to a place not far from the edge, where the scattered things resembled simple factories in the modern suburbs, with low walls cutting out several areas of unfinished clay pots and clay blocks.

Bypassing here, you are close to the edge of the dungeon, but ......

Zhou Tian caught a glimpse of something out of the corner of his eye, and went to the right front, and Zhou Tian immediately raised his breath and followed.

His speed had already increased rapidly, and he reached the edge of the mountain in a few breaths, but Zhou Tian lost the trace of that shadow, and what appeared in front of him was a large round pit, at least more than three meters in diameter.

Zhou Tian cautiously walked to the edge of the pit, looked down, I don't know how deep it is, and I can't see it at a glance.

Zhou Tian looked at it again, but it still didn't work, he couldn't see the bottom, and even the light of the flashlight was swallowed up in the dark.

What exactly is this pit for?

Zhou Tian scratched his head, unwilling to waste more time here, gave up exploring the round pit, and walked to the edge.

Along the edge of the mountain, Zhou Tian found many traces of man-made, as if it was a path that had been carefully groomed.

He looked ahead, and the path reached the end of the mountain, where he did not enter a hole.

Another exit!

Zhou Tian was surprised in his heart, but he still remembered the other three, and he didn't waste much time, turned around and walked back.

By the time he walked back to the tall building, Ghosteye had returned first, sitting on the ground resting.

Seeing that Zhou Tian was back, the ghost eye said, "There is no road over there!"

"I found something, and there's a hole, when they come back, we'll go over and have a look!" Zhou Tian sat down next to Ghost Eye, took out a bottle of water from his backpack and handed it to Ghost Eye.

Ghost Eye took a sip and gave it back to Zhou Tian.

They are now clear about their situation, they are coming in, but they don't know when they will be able to get out, so they can save some of the supplies they bring in.

The two waited for a while, and Black Eagle and Liao Yifei also came back one after another.

"I've found a hole over there!" said Black Hawk.

"I didn't find anything over there!" Liao Yifei said.

"I found a deep pit over there, I can't look to the end, and I found a hole!" Zhou Tian also told his discovery.

The problem now is that Black Hawk is going in the same direction they left last Sunday, and the hole he found should be the one leading to the underground cave.

Therefore, after Zhou Tian and them analyzed it, they all decided to go and see what Zhou Tian found first.

After drinking some water and resting for a while, the four of them walked in the direction where Zhou Tian had just gone.

Zhou Tian didn't tell them that he saw something in a flash, because he hadn't figured out if he was wrong, although it was unlikely, but before he figured it out, he still didn't say it.

The four of them came to the pit, and Black Hawk shook his flashlight inside.

"Unfathomable!" he said.

"It's so deep, what is it for?" Liao Yifei also looked in curiously.

"Don't worry about this for now, you come with me!" Zhou Tian said, walking to the front right, and came to the place he called the path, "You see, is it built by someone!"

"That's right!" Ghost Eye crouched down and touched the ground with his hand.

Black Hawk walked down the path, "I'll go over and have a look!"

Black Eagle followed the path until he reached the entrance of the cave, and he took the hole and shined a flashlight into it.

"Boss, come here!" Black Hawk shouted, and Zhou Tian hurriedly walked over there, "Look!" Black Hawk moved out of the hole.

Zhou Tian took a flashlight and shone it in from the entrance of the cave, and the space inside was very large, and it was very, very large, as if it was no smaller than the dungeon space behind him.

Liao Yifei followed behind curiously and looked inside, "Oh my God! What kind of place is this?"

Ghost Eye frowned and looked at the inside without speaking, he always felt that something was wrong.

"Wait!" Ghosteye said, telling them to get out of the way, and he stood at the entrance of the cave himself.

Zhou Tian looked at the ghost eye curiously, the ghost eye first closed his eyes and took a breath, and then touched the hole next to him and put it in front of his nose to smell it.

"Be careful!" Ghosteye said, "Follow me!"

Zhou Tian won't fail to listen to the ghost eye, because he knows his ability, and here, only the ghost eye can play a role.

The ghost eye took a step towards the entrance of the cave, Zhou Tian followed closely behind, then Liao Yifei, and Black Eagle pressed the formation at the back.

The four of them walked into the hole, a space that was not lit like the big beads on the tall buildings outside, and needed the help of flashlights.

The four rays of light couldn't see the whole space inside, the ghost looked at the ground, and then shook the flashlights on both sides, and walked to the right, there were a few torches against the wall, which was really an unexpected surprise.

took out a lighter and lit four torches, and the four of them could roughly see the situation around about ten meters.

It is a platform similar to a stop, with a pile of unfinished torches piled on the ground, in addition to the platform next to the torches.

And under the table, there is a clay pot, which I think should be placed here to hold water.

Ghost Eye walked to the platform and looked around, but unexpectedly, he found the candlestick!

He took the torch and looked closer, then put his finger in it and dipped something out, put it under his nose and sniffed it, and then put the torch over.

With a "whew", the candlestick was really lit by him, and Zhou Tian and Black Eagle Liao Yifei showed surprise on their faces, it was really convenient, as if it was specially prepared for them.

But then, they were startled by what they saw.

After this candlestick was lit, an extremely thin line of fire appeared next to it, spreading out along the surroundings at an extremely fast speed, even if Zhou Tian wanted to rush over to extinguish it, it was too late.

Then, at a distance of more than ten meters, another candlestick was lit, and in less than a minute, the space was illuminated.

"It's ......"

"Shark oil!" said Ghosteye.

"Shark oil?" Black Hawk wondered.

"Legend has it that the oil made by mermaids, once ignited, will not be extinguished for thousands of years!" Zhou Tian said.

"Is there really a mermaid?" asked Black Hawk again, and from the moment he came in, he had been shocked in all sorts of ways, and they had been immune to the admiration he had uttered from time to time.

"I don't know, I'll know when I have a chance to take it out for testing!" Liao Yifei replied, "I heard that the shark oil lamp in the tomb of King Qin is still on!"

"It's amazing!" Black Hawk patted his head and said, following the boss these days is much more exciting than the previous days.

In the past, at most, when he was protecting his employer, he encountered assassination or something, and it was all pediatric for him.

What he was experiencing now completely changed his previous perceptions, but it also made him even more excited!

Zhou Tian and Ghost Eye stood side by side on the edge of the platform and looked inside, there was no bounding space, high stone roofs, artificially built bridges, stone houses, staircase corridors, and underground rivers flowing under the bridges.

Looking at the buildings here, it is clear that the people who lived here at that time were not of the same class as the people living in the dungeons outside.

Except for the fact that there is no trace of life here, it is almost like a paradise.

It's hard to imagine how the hegemons built such a place in the first place.
