The sound of the gear machinery running softly resounded in the air, farther and farther away.

This is the second time Tang Haoyu has come to the underground place, and Wang Yingyan. The first time was yesterday, and Senior Brother Yun'an.

If the top 5 floor is Disney in the world of departure, then the fifth floor underground is the treasure map in the world of departure.

The first floor is a separate conference room, like the initial barrier of the treasure hunt road, which seems ordinary, but in fact hides mysteries.

After passing through this barrier, there is the command center on the second floor, where hundreds of terminal operating systems are working all the time, and the only sound on this level is the sound of keyboards and hurried footsteps.

And on this floor, the most fascinating and exciting thing is the command platform in the center, the huge screen is above the line of sight, and the screen is full of tight and orderly operating platforms, and the specialists who operate these platforms will transmit important information to the screen, so the space above is constantly divided.

Tang Haoyu heard Song Yunan say that this screen can be divided into 1,001 pieces at most, but it is actually 1,000 pieces, and the extra piece is for the commander to watch movies...... He nodded vigorously without question.

The opposite of the screen is the real-time picture of the earth under the holographic projection, which is wrapped in countless red and green dots, if you want to see the real-time scene of which piece, you only need to swipe and click.

The person standing here is like standing on the sky, as if the world is in his hands, power, balance, as long as he wants, he can get it at his fingertips.

The second floor is like the first discovery on a treasure hunt, and you can't wait to explore it.

The third floor under this sky is the Institute of Biology, when Tang Haoyu visited for the first time, he looked inside from the elevator entrance, this floor is like a biological park, from the river to the ocean, from the sky to the land, rare and exotic beasts, it can be said to be all-inclusive.

In Tang Haoyu's words: I have seen everything, here, I have not seen it, there are here. The point is that he doesn't get angry either.

But when he went deep inside, the next second he looked at him with anticipation, the whole person held on to the tempered glass and began to vomit, his mind was full of the picture just now, and when he eased up, he pulled Song Yunan's clothes and didn't dare to say with complete certainty: "This is harm! It is illegal! It affects the biological balance!"

This is the twists and turns of the treasure hunt, and there is always a price to pay to find the treasure map.

So Song Yunan dragged him down to the fourth floor, and Tang Haoyu, who saw the scene on the fourth floor, was dumbfounded and couldn't believe his eyes.

It's not a 'gambling' center, is it?

A large screen sits in the center of the back wall, with countless white, purple, and green zigzag lines intertwined, and in front of these zigzag lines are the names of companies that I have never heard of.

What's head-scratching is that it's more than just one page, jumping to the next page every 10 seconds.

All around were unkempt, disheveled work specialists, who were making notes on the phone, and every now and then a hoarse sound came from somewhere

Throw!!!

The four-tier economic management department, to be precise, is called a group of crazy departments obsessed with the stock market......

There is also a closed room on this level, with a bright name to keep out the troubled times outside.

Department of Information Management.

Coming to the fourth floor is like encountering a strange event on the road of treasure hunting, and people can't help but wonder if they are on the wrong path.

After visiting the fourth floor, Song Yunan did not continue to take Tang Haoyu to the next floor, because they did not have the permission to go in.

Now, Tang Haoyu, who straightened up and stood next to Wang Yingyan, didn't know that he was about to find the real treasure map.

It is a treasure map to Heaven and Satan's homeland.

He stood upright, his fingers rubbing against his back to keep warm.

This elevator is the most eerie of all the elevators he has ever taken, probably because the basement has not seen light for many years, he always feels that this is an elevator that keeps falling, leading to hell, and inexplicably there is always a feeling that it is not the first time to come here.

Tang Haoyu couldn't help but glance at the floor, originally just because the elevator was descending too slowly, he wanted to see the first floor, but he saw that the elevator had been stopped on the fourth floor, because the number on it was only '-4', and there was no fifth floor.

He subconsciously turned his head to look at Wang Yingyan, and quickly turned his gaze back.

"What's wrong?" Wang Yingyan asked, noticing Tang Haoyu's actions.

"No, it's fine. Tang Haoyu said.

He admired himself a little, and he used this elevator no less than 3 times in the past two days, and he never noticed that the bottom floor of this elevator was only '-4', not '-5'.

When I was with Senior Brother Yun'an yesterday, it was always Senior Brother Yun'an who pressed the elevator, so I didn't pay attention to it, but I didn't notice this problem until I went back from the fourth floor, and even Senior Brother Yun'an said that the fifth floor underground was the awakening room, and when he couldn't enter without permission, he just nodded and said that he was so tired, it was better if he couldn't get in, Senior Brother, let's go back quickly, the elbow at noon was very delicious, and I still want to eat one.

"It's here. Wang Yingyan turned his head and reminded Tang Haoyu.

Tang Haoyu: "???"

He glanced at the floor again, and it was still parked at '-4', how could this go directly? Could it be that the senior brother lied to me, there was another mystery on the fourth floor I visited yesterday?

Just when he had all kinds of conjectures, a button suddenly appeared on Wang Yingyan's right hand.

Tang Haoyu in the back widened his eyes, it's over, he didn't notice how the teacher came up with this button......

This is not a button, but a fingerprint reader, I saw Wang Yingyan put his index finger and looked at the monitor on the floor where the elevator is located, it is not just a monitor, it is also an iris scanning system, green light shoots out from inside and scans Wang Yingyan's face up and down, and when this ray disappears, a gentle and delicate female voice comes out from inside:

"S-level commissioner, Wang Yingyan has passed the certification, this is the 236th time you have come to the awakening room, please abide by the requirements of the room, and I wish you and your student Tang Haoyu a successful awakening. ”

Tang Haoyu gasped, his mind was no longer entangled in the question just now, it was full of: I*, high-tech!

"Stand behind the yellow warning line. Wang Yingyan said with his left arm to protect Tang Haoyu behind him.

Tang Haoyu, who was guarded behind, looked at his feet, it was indeed a yellow warning line, but he didn't remember that there was a warning line when he took this elevator before.

It's over, it's over, it's over, and my brain seems to be watted. Tang Haoyu pretended that he was touching his forehead.

As he stared intently at the warning line, the floor in front of the warning line slowly moved inward, and a passage the size of a man appeared in front of him.

Tang Haoyu blinked his eyes, as if he understood what was going on, but he didn't seem to understand......

"Let's go, follow me, follow closely, it's dark down there, be careful, don't step on the air. Wang Yingyan walked into the passage and said.

"O'O, good. Tang Haoyu followed.

Wang Yingyan is a skilled veteran, and Tang Haoyu is cautiously testing with his toes, and only after confirming that this is an underground passage does he step down.

Tang Haoyu carefully tested the steps, he thought that when he was a child, he climbed the handladder in the countryside, it was easy to go up, and when he came down, he would always keep his chest close to the handladder, use his toes to test the position below, and then go down step by step.

It's really dark below, Tang Haoyu looked down, he couldn't even see his feet clearly, and when he didn't pass the elevator, he looked up at the top, it was very strange and weird, as if there was a film blocked at the entrance of the passage, and the lights in the elevator couldn't shine below.

Compared with the top and bottom, the passage mouth is like the junction of heaven and hell, Tang Haoyu only felt a chill in his back, he turned back and continued to go down.

His vision was dark, he wasn't sure how far away the teacher was from him, he could still hear footsteps when he first came down, and when he went down to the bottom, he couldn't hear anything.

"Teacher?" he shouted.

No one responded.

He tapped on the walls on both sides, his knuckles aching, but there was no sound, he thought of the sound-absorbing material of the Star Lake Hotel, perhaps the facilities here are made of this material so that the sound cannot be heard.

He glanced back at the entrance of the passage, and this time, he felt bad.

The pores of his whole body stood upright, and his feet were soft, and he almost sat down on the steps, and the energy leading to the body seemed to have decreased a lot in an instant, and he made a sound that was insufficient.

He couldn't see anything anymore.

"Teacher?" he shouted again.

Because he couldn't hear it, he wasn't sure if he was shouting out.

He began to feel a lack of oxygen under the great terror, there was always a force constantly pounding his brain, if he could not feel the steps under his feet and the walls on either side, he would have suspected that he had fallen into the abyss.

Tang Haoyu took a step back, dizzy sharply, he wanted to vomit, his body was no longer able for him to stand, he sat down, and banged his head hard, the pain could make people concentrate, covering up the dizziness.

He moved his body backwards with all his might, trying to get out of here, but it was like a wall behind him, and no matter how hard he tried, he still stayed where he was.

Consciousness gradually blurred, in a trance, Tang Haoyu felt that he had landed alone in the glacier area, he held himself, rubbed his arms vigorously with both hands, the cold wind was biting, and it was becoming more and more difficult to breathe under the high-speed whirlpool.

Finally, he couldn't stand it anymore and fell into the snow, the warm snowflakes gradually wrapped around his face, and his vision was blurred layer by layer.

When he woke up again, Tang Haoyu inhaled heavily, and he brushed away the snowflakes on his face, this time he was in a gray mist.

His head was no longer aching, and his thoughts were turning to normal, but the surroundings were surprisingly quiet and the atmosphere was erratic.

Tang Haoyu seemed to forget that he was sitting on the steps of the passage, he began to move towards the deepest part of the mist, his eyes wandered, and before he could get there, a naked man walked out of the mist, Tang Haoyu stopped, but he didn't make any other moves, his expression was still very shallow.

After the man came out, he stopped like Tang Haoyu, his expression was excited and panicked.

"Forget it, you go, I'm tired. Someone said from afar.

Then, Tang Haoyu continued to move forward as if he was being manipulated by this voice.

Suddenly, the fog in front of me dissipated like a low tide, and behind the fog was a cliff.
