Metal door? Encased in masonry?

Lin Yue thought for a moment that he had seen something wrong.

"Xiao Bai, is this the ancient gate of the secret realm?"

"Gah!" Xiao Bai nodded. He tilted his head and looked at the metal door covered with sticky bricks, staring at a piece of rust on the door and responded to Lin Yue.

Good guy, the door to the secret realm opens directly to the basement of your home, so that’s okay.

Lin Yue felt that this was a bit outrageous. Every time before, the ancient gate in the secret realm was outdoors, or at worst it was on the ground.

What the hell is going on underground?

Are you the gate to the underground ruins disguised as the ancient gate of the secret realm? When Xiaobai brought him here, he thought it was the underground ruins stone gate that opened, but he didn't expect it to be from the secret realm.

Are you going to the secret realm... It's night now. Is there any way to go?

He suddenly thought of the situation he encountered last time in the secret realm.

The last secret place was an island, with an airport runway and villas, and a lot of supplies. But when he went in, the secret place there was different from the previous one, because there was a "time difference".

It's night here in the other world, but it's only noon over there in the secret realm. It's different from before.

However, that secret realm is not an ordinary secret realm. According to the system's explanation, it is a "special secret realm", and the special secret realm will only be opened the day before the disaster begins.

But the strange thing is that every time in the past it was a wooden door, but this time it was replaced by a rusty metal door.

Lin Yue immediately put on all the equipment, and Lin Yue did not forget to take the MP19, as well as a sniper rifle, alloy crossbow, etc.

Of course, he did not forget to fill up the replacement magazines for the MP19 pistol and sniper rifle, and he also brought enough ordinary arrows, incendiary arrows, and armor-piercing arrows.

It can be said that this has become a habit of his.

After all, whether it is a different world, a secret realm or an underground ruin, it is a place full of dangers.

The only safe place is his little refuge.

"Try searching?" Lin Yue finished cleaning up, touched the door handle of the metal door, and looked at Xiao Bai at the same time.

Xiaobai didn't stop it, which proved to be safe.

He turned the doorknob and gently opened it, and soon a cold, damp air with a slight odor poured into the basement.

Lin Yue frowned.

The smell made him a little uncomfortable, but when he shined the flashlight inside, he suddenly found that there was something unusual about this place.

Taking a step inside, Lin Yue stepped on a protruding metal.

When the flashlight illuminated it, he was surprised to find that it was a section of railway track!

"Railway? This is..." The flashlight continued to shine in all directions, and Lin Yue unexpectedly discovered that this place seemed to be in a large enclosed space.

The flashlight can shine on the curved cement roof above, while the front is still the cement wall.

Looking back at the platform that was almost 1.5 meters high, and then looking at the two tracks extending forward from his feet, Lin Yue understood what this place was.

"It turns out to be a tunnel in a subway station." He finally understood where the ancient secret door came from.

However, this place is really similar to the underground ruins. They are all straight, empty and cold passages, and you don't know where they lead.

"Gahwu." Xiaobai seemed quite satisfied with this place. After all, the temperature was much lower than that in the other world. It walked forward for a while and called back to him.

There seemed to be no enemies here, but Lin Yue still held the MP19 and did not relax his vigilance.

"What's wrong?" Hearing Xiaobai's voice, Lin Yue chased after him, but soon discovered what he had discovered.

"Good guy, has it collapsed?" Lin Yue discovered that the vault at the exit tunnel in front had collapsed, directly blocking the way to the farther place, making it impossible to move forward at all.

Lin Yue looked at it but did not put it into the storage space.

valley

Who knows how many things are pressed and whether it is safe?

If a little bit is taken away, the world will collapse and everything will be over.

"Gah!" Xiaobai raised his forearm, looked in another direction, and ran over again.

Lin Yue ran over and saw the same result as before.

"What's the situation? Both sides are blocked, but it's okay." Lin Yue felt that he had come to a crappy subway station.

However, it's not all bad here.

The rails under your feet are a good thing anyway.

What kind of metal are the subway tracks made of? Although Lin Yue didn't know much about it, he thought it was all made of alloy.

His hands touched the tracks, and they were quickly put into the storage space.

I have to say that this thing is really heavy. Halfway through the installation, he found that the storage space was full, so he went back to the shelter and put one on the ground. As a result, it made an extremely dull sound.

After flipping back and forth three times, Lin Yue finally collected all the tracks and looked back at the platform.

Although this place is underground and there is no way to know whether it is dark or day outside, he still decided to explore again tomorrow. Going out now is too risky.

"Xiao Bai, let's go back first, we will gain a lot."

It’s really outrageous. The number of tracks is really quite large now.

If they were all turned into raw materials, how many would there be?

Lin Yue reopened the door and took Xiaobai back inside.

However, when he closed the door, Xiaobai suddenly turned his head and roared at the metal door!

Lin Yue turned his head sharply at the same time, but all he could see with his pistol was the rusty iron door.

Is there anything coming out on the other side of the door?

But, how come it’s such a coincidence?

Lin Yue did not put down his pistol. The lizard people had opened the door that time. Although this was based on the premise that they were creatures with certain intelligence, who could guarantee that there would not be lizard people in the secret realm?

After looking at the wall deep in the lizard man's cave, Lin Yue felt more and more that the monster pterosaurs, tentacle monsters, etc. were originally all creatures in this other world, and were transferred to the world decades later by some special force.

Earth.

But he didn't understand why only the lizard people stayed here.

Moreover, he is also very concerned about the orcs with wolf-like ears. Are they extinct, or are they hidden in this other world, or even in a secret realm?

M19 took aim for a while, but nothing happened, but Xiaobai seemed to be extremely vigilant.

This made Lin Yue couldn't help but remember that this happened twice before.

"Xiao Bai, step back and I'll seal this place again." Lin Yue greeted Xiao Bai.

It's better to be careful when doing things outside. There is nothing worth picking up at the subway station. It's too dark now, and Xiaobai is so alert, so he has no reason to go in and take a look.

It would be better to simply seal it directly.

Xiao Bai exited the door, and Lin Yue built a stone wall to block it like last time.

In this way, even if the door is opened, it will face an extremely thick stone wall, making it impossible to break in.

Lin Yue breathed a sigh of relief, turned around and suddenly remembered something.

"Xiao Bai, where is the stone gate of the underground ruins?"

Xiaobai led Lin Yue to the rightmost one of the three emergency movement channels and called to him.

Lin Yue saw that the original wooden door there had now turned into a wooden door with strange patterns composed of lines and circles.
