After about ten minutes of walking, the style changed abruptly after another corner of the promenade.

A long corridor paved with cyan bricks with an antique atmosphere appeared in front of the young man's eyes.

The bricks are neatly arranged on the pavement of the corridor and on both sides of the wall, and the green bricks on both sides of the wall are cut relatively narrow, each with a length of about 60 cm and a width of 30 cm, overlapping each other and half of them are attached to the wall.

The green bricks on the ground are arranged more elegantly, and the green bricks have a square green brick of about 1 meter every few meters, which is carved with various reliefs, and then some small green bricks are neatly arranged around the square green bricks to form a matrix pattern.

Gu Moxun looked at these green bricks that revealed a little golden light, and couldn't help but touch the surface of the green bricks with his hand curiously.

The green bricks do not have the coldness of metal, and there are some fine bumps on the surface when you touch them, and a frost-like texture, which makes people feel very comfortable.

With a flick of your finger, it makes a metallic crisp sound, but it is thicker than the metallic sound.

The old man heard Gu Moxun's knocking, and said without looking back: "These green bricks are made of cosmic dust, they are very strong, okay!" You keep up, you're almost there."

As he spoke, the figure of the old man did not pass the next corner, leaving only the voice echoing in place.

Gu Moxun didn't dare to stay longer after hearing it. Hurry to the corner.

Suddenly, a tall bronze door stood in front of me!

Gu Moxun, who didn't have time to stop, almost bumped into Wei Zhengdao, who stopped in front of him.

The young man who had a false alarm hurriedly stood up and looked at the gate carefully with curiosity.

The gate is made of bronze and is similar in color to the blue bricks, giving it a sense of unity.

But this door is supposed to be older than the bricks, giving people the feeling of going back to ancient times. The huge bronze door is carved with intricate reliefs and patterns that come to life like a living thing.

……

Wait a minute!

No!

suddenly

In the eyes of the teenager...

The pattern on this door seems to be really moving...

The intricate pattern was spinning. And it's getting faster and faster, and it's converging towards the center to form a dot.

And the boy's mind seems to drift towards the center dot with the rotation of the pattern...

When all the patterns were gathered at one point, Gu Moxun couldn't tell whether the dots had stopped or continued to rotate.

Gu Moxun's mind seemed to fly uncontrollably towards the dot, and the dot grew bigger and bigger with his mind.

By the time Gu Moxun walked into the dot, the dot had become about the size of a small cave, and his mind was drifting inward.

It was pitch black inside, and he drifted farther and farther inside, but his heart was extremely calm, and there was only a feeling of ethereal sky.

It was as if there was no body anymore, but a mind floating in a black hole.

I don't know how long it took, but suddenly a huge force grabbed his left shoulder and pulled him out backwards...

As he retreated, Gu Moxun saw a black wire of the dot rotating rapidly, rotating outward from the center of the dot inside.

After a while, it turned into a black dragon and attacked Gu Moxun!

Before the boy could react, a wave of blood boiled, and a dizzy feeling poured out of his head and stomach.

Gu Moxun staggered, half-knelt on the ground, coughed dryly twice, but couldn't spit out anything.

Look up again. I don't know when I came to the gate, and my right hand was placed on the bronze door with five fingers open.

And on his left shoulder is the warm hand of Wei Zhengdao.

Gu Moxun wiped the saliva from the corner of his mouth with his left hand

Slowly stood up and asked:

"It's so strange, I feel like my soul is going to be sucked into him."

The old man looked at the young man, but did not answer his words directly, but asked:

"What do you see in there?"

"Oh, I didn't seem to see anything, and I started to see a rotating black dot, and I wanted to look at it more closely, but the whole person involuntarily flew into the black dot, and... I didn't seem to see anything, except when I came out, I seemed to see a monster flying towards me that I didn't know if it was a black dragon or a black snake, and then I woke up. ”

The boy stammered a little as he told what he had seen.

Wei Zhengdao stared at the young man's eyes for a while, and didn't seem to notice that the young man was lying again, so he said:

This door is called "heart door", it was brought up by the predecessors from the old world, it was found in a very old ruins, the relief and pattern on the door have the effect of confusing the mind, the heart of the sneaky person, you will see the malice in your heart, and be defeated by your own malice, the righteous person, will strengthen your faith, the dot you see should be a chaotic confusion, indicating that your consciousness is still chaotic, there is no good and evil. But fortunately, he is kind-hearted and has no evil thoughts. This is your first test, the results are so-so, and you can be considered passed! ”

The boy heard that he had passed the test in a daze, and he wanted to laugh happily. As a result, the old man stretched out his hand and lightly pushed on the huge bronze door, and the door slowly opened.

"Come in with me, this is my residence, and it will be the base camp of our two "guides" in the future! This place is called Between Civilizations. The old man said as he opened the door.

Gu Moxun was thinking about how much strength the old man used to push open the huge bronze door, but he was shocked by the scene behind the door.

I saw that the lights behind the giant gate were bright, and there was a lot of brilliance everywhere.

The old man said that this place was called between civilizations, but the young man thought that it might be more appropriate to call it the cave of civilization, which was still the kind of towering and huge cave.

This hall, which has a drop of more than 50 meters, makes the teenager feel small all of a sudden.

Models of various galaxies, planets, and stars float in the dome and orbit along their own orbits.

And the boy knew at a glance that these models were all the planets and galaxies discovered and colonized by human civilization in the new era/era/era.

And the depth of this cave is also very vast, which is really to be described as vast. It's almost the width of two football fields.

Gu Moxun and the others were standing on the semicircular steps at the entrance of the gate, and this semicircular step was almost ten meters above the ground. It is just the right time to get a full view of the entire "between civilizations".

I saw that there were large cabinets below, which seemed to be arranged in a regular way and divided into areas.

The material of the cabinets is also different, most of them are wooden cabinets, some are made of metal, and some are made of glass and other spars.

And the contents are all-encompassing, and they are different.

As far as Gu Moxun can recognize, there are various animal and plant specimens, various ores, specimens of spars, various types of machinery, and prototypes of firearms.

There are a lot of unknown things, either on the platform, or sealed up...
