Metal doors? Wrapped in masonry?

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

"Xiaobai, this is the Ancient Gate of the Secret Realm?"

"Quack!" Xiao Bai nodded, it tilted its head to look at the metal door wrapped in sticky masonry, and its eyes stared at a piece of rust on the door in response to Lin Yue.

Good guy, it's okay to open the door of the secret realm directly to your basement.

Lin Yue felt that this was a bit outrageous, every time the Ancient Gate of the Secret Realm was outdoors before, and no matter how bad it was, it was on the ground.

What the hell is this underground?

Are you the Gate of the Underground Ruins disguised as the Ancient Gate of the Secret Realm? When it was brought over by Xiaobai, he thought it was the underground ruins stone door that had opened, but he didn't expect it to be a secret realm.

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

He suddenly thought of the situation he had encountered in the last 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 realm there was different from before, and there was a "time difference".

It's night on the other side, and it's noon on the secret world, which is different from before.

However, that secret realm is not an ordinary secret realm, according to the system, it is a "special secret realm", and the special secret realm will only open the day before the disaster begins.

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

Immediately put on all the equipment, Lin Yue did not forget to hold the MP19, as well as sniper rifles, alloy crossbows and so on.

Of course, he didn't forget to fill the replacement magazines for MP19 pistols and sniper rifles, and he also brought enough ordinary arrows, incendiary arrows, and armor-piercing arrows.

It can be said that this is already a habit of his.

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

The only safe place was his little shelter.

"Try searching?" Lin Yue finished cleaning up, touched the doorknob of the metal door with his hand, and looked at Xiaobai at the same time.

Xiaobai did not stop it, and it turned out to be very safe.

Twist the doorknob and pull it open slightly, and soon a cold, damp, slightly smelly air pours into the basement.

Lin Yue frowned.

The smell made him a little uncomfortable, but when he shone his flashlight inside, he suddenly noticed that there was something unusual about the place.

Taking a step inward, Lin Yue stepped on a protruding metal under his feet.

The light of the flashlight shone on, and he was surprised to find that it was a section of railroad tracks!

"Rails? This is ......" The flashlight continued to shine in all directions, and Lin Yue was surprised to find that this place seemed to be located in a large enclosed space.

The flashlight can shine on the curved concrete roof above, while the concrete wall is still in front of it.

Looking back at the platform that was almost one and a half meters high, and then looking at the two tracks that had been extending forward under his feet, Lin Yue understood what kind of place this was.

"It turned out to be a tunnel in a subway station." He finally understood where the Ancient Gate of the Secret Realm had come this time.

However, this place is really similar to the underground ruins, they are all straight, hollow, and cold passages, and I don't know where to go.

"Quack." Xiaobai seemed to be quite satisfied with this place, after all, the temperature was much lower than that of the other world, and it walked forward for a while, and turned back to call him.

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

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

"Good fellow, collapsed?" Lin Yue found that the vault of the exit tunnel in front of him had collapsed, directly blocking the position leading to the farther place, and it was impossible to move forward at all.

Lin Yue looked at it and didn't put it in the storage space.

Who knows how many things are pressed, and it is not safe?

If you take a little bit away, it will be completely over.

"Quack!" Xiaobai's forearms were raised, and he looked in another direction and ran over again.

Lin Yue ran over and saw the same result as just now.

"What's the situation, it's okay if both sides are blocked." Lin Yue felt that he had come to a tofu scum subway station.

It's not for nothing, though.

The rails under your feet are a good thing.

What metal is the track of the subway? Although Lin Yue didn't understand, he felt that this thing was an alloy.

Hands touch the tracks, and they're quickly tucked into the storage space.

I have to say, this thing is really heavy, he halfway through the load and found that the storage space is full, he went back to the shelter, put one on the ground, and it made an extremely dull sound.

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

Although it was said that it was underground, there was no way to know if it was dark or daylight outside, but he decided to come back tomorrow to explore, and it would be too risky to go out this time.

"Xiaobai, let's go back first, we have gained a lot."

It's outrageous, the number of tracks is really a lot now.

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

Lin Yue reopened the door and re-entered it with Xiaobai.

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

Lin Yue turned his head sharply at the same time, but the pistol only aimed at the rusty iron door.

Is there anything coming out of the door?

However, how can it be so coincidental?

Lin Yue didn't put down the pistol, that time the lizardmen had opened the door, although this was on the premise that they were creatures with a certain amount of intelligence, but who could guarantee that there would be no lizardmen in the secret realm?

After looking at the wall in the depths of the lizardman cave, Lin Yue felt more and more that the monster pterosaurs, tentacle monsters, etc., were originally all the creatures in this other world, and they were transferred to the earth decades later by some special power.

But he didn't understand why the lizardmen were the only ones who stayed here.

Moreover, the orcs with wolf-like ears are also quite concerned, are they extinct, or are they hidden in this other world, or even a secret realm?

M19 looked at it for a while, but nothing happened, but Xiaobai seemed to be extremely alert.

This reminded Lin Yue that there seemed to be this two times before.

"Xiaobai, stand back, I'll seal this place again." Lin Yue greeted Xiaobai.

It's better to be careful about foreign affairs, there is nothing worth getting at the subway station, and now it's too dark, and Xiaobai is so vigilant, he has no reason to go in and see it again.

It's good to just seal it directly.

Xiao Bai withdrew from the door, and Lin Yue made a stone wall to block it like last time.

In this way, even if the door is opened, it will be faced with an extremely thick stone wall, and it will not be possible to break through at all.

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

"Xiaobai, where is the stone gate of the underground ruins?"

Xiao Bai took Lin Yue to the side of the rightmost of the three emergency movement passages and called out to him.

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

Just like he'd seen countless times before.
