"This house looks like it's been around for some years!"

Luo Chong found that the house was made of metal, but due to its age, it was already rusty, and there were traces of being chopped by a sword, which looked quite vicissitudes and heaviness.

"Is this the strange man's residence, or is there another mystery?" Luo Chong faintly felt that there must be some hidden secret in this mermaid palace! And this room may be a key to unlocking this secret.

Luo Chong hesitated for a moment, then reached out and pushed the iron door open a crack.

From the crack in the door, this house is extremely simple and narrow, except for a few simple tables and chairs, it is some dilapidated daily furniture, and there is a faint pungent musty smell, if ordinary people come to see, they must think that this is a dilapidated house that has been uninhabited for a long time.

But Luo Chong wouldn't think so, because in this small house, he didn't see the strange man just now!

The space in the house is not large, and the home is extremely simple, even if it is hidden, the strange man has no place to hide!

The only explanation is that there is a secret passage in this house.

"Crunch~!"

With the sound of gold and iron, the iron door was slowly pushed open by Luo Chong, he listened intently for a long time, and found that there was no movement in the room, so he carefully squeezed in through the crack in the door.

The house was not large, the tattered tables, chairs and furniture were lying crookedly, and out of nowhere there was a musty smell, and the corners of the room were covered with cobwebs.

Luo Chong looked around, and suddenly found a faint layer of dust on the ground, and there was a row of huge footprints on the dust.

This footprint is extraordinarily large, it looks close to half a meter, and the toes and soles of the feet are exceptionally clear, and they are stepped on with bare feet, which makes Luo Chong think of the huge strange man just now.

Such a big footprint should have been left by the strange man.

Luo Chong looked along the footprints and found that the footprints had been winding forward, and finally disappeared in front of a wall.

"Although the secret room seems mysterious, it is not difficult to find!" Luo Chongjing walked to the front of the wall. The wall had clearly been slashed by a sword, and it was covered with knife marks, sword marks, and even a few arrows broken inside.

"All of this must be a trick!"

Luo Chong thought for a moment, reached out to touch the broken arrows, and finally, one of the arrows made a crisp sound of "click!" and stuck into the wall.

Boom ——!

With a rumbling sound, the wall shifted to the side, revealing a staircase leading to the ground behind.

"Everything here is an illusion, including the marks on the walls and broken arrows, all to confuse outsiders!" Luo Chong thought of all this, and couldn't help but be secretly frightened, the layout of this room is enough to confuse the real with the fake, but why did the people of the Mermaid Palace set up a secret room here, and what secrets did they hide?

Luo Chong walked into the secret room and walked down the steps all the way to the ground.

The steps were wide and long, and Luo Chong had to take at least two steps to step on, and every few meters there was a copper lampholder on the wall, with torches on it, to illuminate the passage.

"My current position is about twelve or thirteen meters underground, this secret room is really deep enough!" Luo Chong walked while estimating his position.

After walking for a while, Luo Chong finally faintly heard a burst of anxious talking not far away.

“...... Damn! Damn! Damn! Failed again! Why is this happening, it doesn't make sense at all, according to my calculations, there can be no accident! This situation is simply not possible, it is impossible to ......!"

"Bang!"

"Ouch~!"

It sounded like the man's head had hit something.

"You big shit, what are you doing here, you hurt me! Such a big place, if you don't follow my ass, get out of the way!"

......

Listening to the man's chatter, Luo Chong's curiosity increased, he slowed his steps, walked forward, and after turning a corner, a wide room finally appeared in front of him.

This room looks like it is about more than 200 square meters, although it is not particularly large, but after all, this is more than ten meters underground, and the difficulty of building such a room here can be imagined!

Moreover, this room is also full of all kinds of utensils, bottles and cans, and a large number of books.

Luo Chong probed a little and found the person who spoke just now, as well as the huge strange man he saw earlier.

Luo Chong found that the person who spoke was extremely short, and he didn't seem to be much stronger than a dwarf, but his head was very large, bald in the middle, a circle of gray hair around him was messed up into a nest of grass, and a pair of bloodshot eyes were full of tiredness and irritability.

It seems that this man is not young, but his body is like that of a child.

"Damn, I'll do one last experiment, if it's not successful, I'll strike, don't do it!" The big-headed old man shook his head vigorously, muttering anxiously, he took a metal tube from the side and put it into the slot of a metal instrument in front of him, the metal tube contained some liquid, and it was emitting purple mist.

"What kind of experiment is this guy doing?" Luo Chong stared at the old man intently, but he felt in his heart that the other party's experiment must be something that cannot be seen.

Looking at the dazzled old man with the big head, he operated for a long time, and finally took out a bottle of potion from the instrument, and said with a little confusion in his eyes:

"Let's hope it works this time!"

Turning his head to look at the huge strange man, the old man with the big head said, "Big head, you go and bring the experiment!"

When the giant strange man heard this, he nodded blankly, then turned around stiffly, came to a huge curtain, grabbed it with his big hand, and lifted the curtain.

Luo Chong was surprised to find that behind this tent, there were metal cages, and there were small rats and rabbits in the cages, as large as leopards and lion tigers...... Even in a cage, there is a human being in captivity!

It's just that these creatures are now in a coma, so they don't make a sound.

Luo Chong instantly understood that this guy actually used these creatures for experiments, including humans!

For a while, Luo Chong couldn't help but be angry in his chest, and he almost rushed forward and chopped off the big head pervert in front of him with a knife.

However, Luo Chong knew that it was not the time yet, and he had to wait and see.

The giant monster glanced at the metal cage, and finally reached out and grabbed the metal cage where the human was imprisoned, and carried it to the old man with the big head.

In the metal cage, there was a young man, but he was naked at the moment, lying in the cage with his eyes closed, and his body was already a little swollen and bruised.

"Bang dang~!"

The giant monster threw the iron cage directly in front of the big-headed old man.
