Speaking of which, this trick is just a visual illusion, and it is not mysterious to say it out loud.

Chen Ziyan's eyes swept through the mezzanine in front of him and found that the area here was about 20 square meters, and he could not see the specific function.

He knew very little about this, far from the military literacy of Hu Bayi.

Thinking of this, Chen Ziyan took out a hiking rope from his backpack and put it down along the wall.

At the same time, he leaned his head and said to the two people below: "I didn't expect there was something wrong with this place. You can come and have a look."

Hu Bayi and Wang Kaixuan were originally seeing Chen Ziyan disappear suddenly and were about to call out, but now when he saw him put down the rope, he immediately understood that he was fine.

While letting go of worries, I couldn't help but feel a little curious.

After the rope was put down, he quickly climbed up with the force.

"Be good! This little Japanese man is quite insidious, and he actually hides a hand here!" Wang Kaixuan couldn't help but say after seeing the mezzanine above.

They would never have thought that there would be such a hidden mezzanine here.

There is nothing set at the edge, but there is no trace at all.

It's also a wonderful means!

"This should be the command room of this fortress." Hu Bayi easily accepted the existence of this place.

After seeing this place, he already knew what was going on.

Seeing that Chen Ziyan and Wang Kaixuan were a little puzzled, they explained to them:

"Looking at the layout here, the middle is a conference table for making decisions. The row next to it seems to be the location of the correspondent, and this row is used by secretarial workers such as scribes."

After talking about the layout here, Hu Bayi looked at a door in the corner that had been crushed by rocks: "It should be the entrance and exit of this command room, but it seemed that it was also blown up when the Kwantung Army evacuated."

After exploring the nest of the pig-faced bat, he had already inferred from the fortress map in his hand that the first floor of the fortress, which was the one with a formal exit, had been completely blown up as early as when the garrison evacuated here.

The location of the bat cave is the transit station between the two floors, and it is also the only connection point.

If they hadn't accidentally discovered an underground passage in the tomb of the General of the Jin Dynasty, the fortress would have probably been sleeping underground and would never have been discovered.

"It seems that those big land otters came out of this hole." At this moment, Wang Kaixuan's voice talking to himself attracted the attention of both of them.

Chen Ziyan and Hu Bayi looked in his direction and found that Wang Kaixuan was standing by the wall on the right, looking at a cave above with a flashlight.

"That's right." Chen Ziyan nodded: "This cave should be the nest leading to those grassland landosters."

Chen Ziyan had already thought of this when he saw this cave.

This can also explain why after he heard the movement from above, the prairie land otters jumped down one by one.

"Then let's go and have a look?" Wang Kaixuan turned his eyes terrifiedly when he heard Chen Ziyan's words and suggested.

He felt that the prairie land otter had been here for many years, and he probably had something in his nest.

The play always says that the strange beasts in the mountains like to collect wandering treasures. Wang Kaixuan thinks that the shape of the earth otter in the grassland can be somewhat intertwined with the edges of the strange beasts.

Rounding in one by one does not mean that there will be treasures in their old nests.

Of course, when Wang Kaixuan put a pseudo-animal label on the grassland otter, he never remembered that he was calling someone a beast just now.

"Now those grassland otters are in the maintenance room below, so it's okay to go and have a look. What do you think, Mr. Chen?"

Hu Bayi was also a little moved. According to the greedyness of the grassland land otters, they probably were locked up in the maintenance room below.

This means that the hole in front of you is not dangerous at this time.

In this case, it would be a little bit of a pity if you don’t go in and find out.

"Then go and have a look." Chen Ziyan had no objection to this, but he felt he had to be more secure, so he said, "But it's not possible now. We have to feed the guys below before entering."

Although these grassland land otters were all asleep, who knew if they would get up to find food?

Chen Ziyan knew one truth deeply, that is, never underestimate the power a foodie can burst out when she is hungry!

What's more, under their feet, they are not just a foodie, but a nest.

"Yes, yes! Mr. Chen is still considerate!" Wang Kaixuan immediately understood Chen Ziyan's plan.

As he said that, he planned to go down to make a fire and give the grassland land otters a barbecue.

Hu Bayi looked at the impatient fat man and quickly stopped him: "Don't do it blindly. If you barbecue meat here, the prairie land otter would not go crazy if you smell it."

They have seen the power of this barbecue, and now they cannot lose their big things because of small things.

Chen Ziyan also thought of this and said, "It's better to take it to the top and bake it, and then take it down and feed them."

Wang Kaixuan slapped his head when he heard this: "I'm confused, I'll take the things on it."

This time no one continued to stop him. Since this fat man took the initiative to do things, they just happened to save some trouble.

After Wang Kaixuan went down, Hu Bayi looked at the hole on the wall and asked Chen Ziyan: "Master Chen, if I read it correctly, the direction of the hole should be facing down. Do you think we can find the third floor?"

They had been walking around the second floor fortress for more than a while, but they had not found the entrance to the third floor so far.

If you don’t find the command room in front of you, it can be said that the entrance to the third floor is inside another mountain.

But now that even the command room is here, there is no reason why the entrance to the third floor will be in other areas.

In fact, what Hu Bayi didn't say was that he had always had a vague feeling that the third floor of the mysterious fortress seemed to have something extremely important to him.

This is why he agreed to Wang Kaixuan so happily just now, just to try whether this place can lead to the third level.

Chen Ziyan did not respond immediately, but asked: "Lao Hu, why do you think of studying the traces of the ceiling?"

He suddenly felt that it seemed like it was too coincidental.

They just left the maintenance room together, but neither himself nor Hu Bayi nor Wang Kaixuan had thought about going to see the traces left by the land otters on the grassland.

Why did Hu Bayi and the others suddenly remember this after they had finished replenishing their ammunition?

This seems to be fine, but it is actually a bit too reasonable.

The main reason is that there are a lot of evil things in this fortress, so Chen Ziyan has to be on guard.
