Su Yao's words resounded in Tang Ling's ears, but they turned into a meaningless 'buzz' sound.

Because the brain that was too shocked could no longer receive the meaning of Su Yao's words.

Behind the door, the dazzling lights were like the brightest night, and the twinkling stars wrapped in a noisy, lively and alternative atmosphere, enveloping Tang Ling.

The small door behind him closed silently.

With a look of smiling rather than smiling, Su Yao lit another cigarette, leaned against the door, and quietly looked at the shocked Tang Ling.

His eyes narrowed as if he remembered some distant past, and he spoke: "Once, I and—" but he kept silent after just four words, just letting the smoke blur his face.

Tang Ling couldn't notice this kind of detail.

A full dozen seconds passed, and Tang Ling still couldn't believe the 'reality' in front of him.

The tall and exquisite buildings of the so-called pre-civilization that I once saw in the pictures of my mother-in-law scavenging from the waste, actually existed, and they were best preserved within the walls of Security Zone 17.

In addition, there are some strange buildings that have never been seen before.

Night, as if it were the best reason for these buildings to 'revel', adorned them with thousands of twinkling lights.

In the midst of such magnificence, the crowd also became dense.

If the people in Security Zone 17 outside the wall are still a little dull, the three repeated shades of black, gray and blue represent almost everything.

Here, it made Tang Ling realize for the first time that things like clothes still have the function of decoration, making the people walking in this wall with a leisurely look so proud and noble.

There are also all kinds of indescribable wonderful sounds, mixed together, some noisy, some beautiful, converging into a moving night song.

"It's the first time I've seen a place like this, and no one can be calm." Su Yao took a cigarette in his mouth and touched Tang Ling's head a little kindly.

Tang Ling came back to his senses and wanted to say something to Su Yao, but all the words were blocked in his throat.

Only the instinct of precision informed Tang Ling of the most precise distance, from the place closest to the wall of the safe zone to the center of the 17th safe zone.

If it's a straight line, it's only 5,127 meters.

But there are two walls, forming three completely different huge circles of life.

Outside the circle, you can't imagine life in the circle, but inside the circle can step on everything outside the circle.

Straight-line distance didn't mean anything, he only understood it for the first time, and there were countless mockery behind the cold numbers.

"Let's go." Su Yao threw away the cigarette roll and patted Tang Ling on the back.

Tang Ling nodded wordlessly.

**

Ten minutes later, Su Yao took Tang Ling to a strange building.

The building is small, but hundreds of meters high, with a diamond-shaped body made up of a few white curved columns, and then the entire façade is covered with reflective but opaque material.

It's quite mysterious.

"Training Base." Tang Ling read the words in front of the door of the building, and he understood what this building was for.

"Let's go inside." Su Yao didn't show any surprise at Tang Ling's inexplicable ability to speak a pre-civilized language, just said something calmly, and pulled Tang Ling into the building.

However, Tang Ling noticed that the Tower of Babel, which went straight into the sky, stood in front of the left side of this training base, only more than twenty meters away.

The first time he was so close to it, Tang Ling felt a strange vibration in his heart, shaking every trace of blood in his body, as if speeding up their flow.

This made Tang Ling quite surprised, but this feeling came and went quickly, and he couldn't feel it at all after entering the door.

"Come here." Su Yao called out to Tang Ling, who was still in a daze.

And Tang Ling, who came back to his senses, finally saw the interior of the building clearly.

The soft white light illuminates every corner, but the light source is nowhere to be found.

The place he and Su Yao occupied was an empty hexagonal hall that was empty except for a circular bar made up of unknown metal cabinets.

The six sides that surround the hall are connected by corridors, and behind the corridors are six-diamond-shaped doors.

The middle door has the largest number of doors, and the lowest and highest doors are huge, but there are only a few doors.

It looks a bit like a beehive, but it's not quite the same.

"I want a basic training room." Su Yao was standing in front of the metal counter at this time, and said casually to the beautiful woman standing behind the counter.

With a smile that didn't actually mean anything, the woman said indifferently, "Five hundred credits." ”

This number shocked Tang Ling, he had never earned so many credits in his life until now.

Credits, on the other hand, are the common currency of Security Zone 17 and are in the form of small metal discs that cannot be imitated.

In general, the credit points in the settlement are uniformly released by the No. 17 security zone.

One disc and one credit.

Seeing that Su Yao was just wrapped in a black fur coat with an open chest, where could he put 500 credits?

Su Yao seemed to see through Tang Ling's thoughts, and he smiled a little hatefully, and then took out a crystal badge, which was similar to the one given to Tang Ling before entering the inner wall, but it was much more transparent.

The beautiful woman took Su Yao's badge and pasted it somewhere on the metal counter, and after a crisp 'drip' sound, the woman had already handed the badge to Su Yao along with a metal card.

"Room 6F-019." The woman said this.

Su Yao took the things, turned around and left with Tang Ling, although he pressed it countless times, Tang Ling couldn't help but ask Su Yao: "Uncle Su Yao, did you give her money?" ”

"Hahaha." Su Yao burst out with a smug laugh, and then rubbed Tang Ling's head vigorously: "What do you say?" Do you think I should carry a big bag with bits and pieces of metal? ”

"In the security zone, the credits are stored inside the identity badge. It's the one I gave you. ”

"I deposited 1000 credits into it. In short, about the identity badge, you will understand later. Su Yao never explained too much, and as he spoke, he had already led Tang Ling into a huge six-diamond-shaped door.

The door was still glowing in a soft white light, but it was empty, and there was only room for three or five people.

And Tang Ling didn't care about this, he even became short of breath - 1000 credits?!

The number was like a hot flame, so hot that he didn't even bother to pay attention to any details, just tightly grasped the identity badge in his trouser pocket.

He will not be polite to Su Yao, treat kindness, Tang Ling has Tang Ling's way.

There was a slight tremor, and the huge six-diamond-shaped gate that had just entered opened again.

When they came out again, they were already in the hallway marked 6F.
