After waiting for a few minutes, there was no sound of rolling stones, and Xu Xin and the four stone statues crawled out of the small hole.
Chang Yin slapped the wall again, and the originally concave hole gradually became shallower, and finally returned to its original flatness.
"I have obsessive-compulsive disorder. I can't stand leaving a hole in the wall." Changyin explained with his hands spread out.
Xu Xin pointed to the back, where several huge boulders blocked the way. "It looks like we can only move forward."
"Why, do you still want to go back?" Chang Yin glanced at the rolling stone behind him and said indifferently, "If you really want to go back, I can take you back. How can a stone block my way?"
Xu Xin understood. Chang Yin's ability seemed to be to control rocks. Although he might not be able to stop the rolling of the boulders, it would be no problem to break the stationary boulders into pieces.
"Are there any more mechanisms ahead?" Xu Xin asked.
"No more," Xue Lan held the little boy's hand, "Last time, until the first door, there was only this kind of mechanism, and the rolling stone only appeared three times."
Continuing to move forward, they soon caught up with the mutant cheetah that was lying on the ground waiting for them to catch up.
Xu Xin passed by the cheetah and subconsciously wanted to touch the big cat's head, but the cat easily dodged him again and then followed him silently at a distance of two meters behind him.
There was no other way, Xu Xin could only touch the sleeping Coco's head on his shoulder. Coco twisted slightly, made a sound like she was talking in her sleep, and continued to sleep soundly.
The tunnel became wider and wider.
Xu Xin could already see a big door not far away.
It was a door similar to the entrance to a dungeon, but several times larger, as big as the gate of a castle.
Several people quickly arrived at the door. Chang Yin tried it himself first, but no matter how hard he slapped, the metal door remained motionless.
Xu Xin looked up and found a downward-opening hole directly above him. The hole was about the same size as the rolling stone and was probably where the rolling stone came out.
At this time, the bat that had been signed earlier came in handy. Xu Xin turned the ring with his thumb, and the mutant bat appeared in front of Xu Xin.
"Huh? You have also contracted a bat." Chang Yin looked at the big bat with some surprise.
"Go to the cave above and see if there is anything we can bring down." Xu Xin first directed the bat to fly into the cave above, and then answered Chang Yin, "It will be much more convenient to have a flying bat."
"Yeah... that's true, but the strength of a single bat is very average, we need a lot of them to have some combat power."
After asking, Xu Xin learned that these bats were actually just failed products of Chang Yin and his team's experiments.
The current mutant beast potion is the final version debugged by Chang Yin and Xue Lan through various experiments. The initial effect was very weak, and the bats in the staircase passage were the initial test subjects.
After absorbing the initial experimental drug, the bats did mutate and gained certain special abilities, but the ability of each bat was too weak, and they had to work together in groups for their abilities to manifest.
Xu Xin had suffered a loss at the hands of a swarm of hundreds of bats. Thinking back on how he felt at that time, his head even started to ache again.
"The ability of a bat swarm is to produce ultrasonic waves that can affect people's minds." Xue Lan was also very familiar with the test subjects, and explained to Xu Xin, "But a single bat is useless. It is just a little bigger than an ordinary bat and has a longer lifespan."
Before Xu Xin could say anything else, the bat that had flown into the cave above flapped its wings and flew down, holding a walnut-sized red stone in its claws.
"Look, doesn't it still have some effect?" Xu Xin reached out to catch the small round red stone, and when he looked closely, he found that the stone actually emitted a blue light.
It's actually a blue-grade stone.
Contaminated Radiation Stone (Blue): emits special radiation with a range of ten meters. The mutant beasts affected by it for a long time will become stronger! Don't worry, this radiation is harmless to normal people and normal beasts.
When Xu Xin saw the word "radiation", he almost threw the stone away. He was relieved only after reading the introduction below.
After understanding the function of this stone, Xu Xin couldn't help but smile. It turned out to be a tool that could make mutant beasts stronger! This was simply what he wanted.
The mutant cheetah is now just at the edge of low-level and medium-level. As long as it can become stronger, it can be directly upgraded to a medium-level beast! And the stronger bat can also play a greater role.
I didn't expect to find such an unexpected surprise here.
"What? Is this stone useful?" Chang Yin asked, looking at the stone in Xu Xin's hand.
"It's nothing, just a piece of stone that can be used to make weapons." Xu Xin put the stone into his backpack.
"Weapons? That's boring. My body is the weapon. Okay, push the door." Changyin pointed to the door in front.
Xu Xin walked to the door and reached out to touch it.
"Huh?" A familiar feeling rose from the bottom of my heart. This feeling is... a tree house
It was like pulling the roots of the tree house, and it felt as if it had merged with me. Could it be that the roots of the tree house were affecting the door here
With a gentle push, the huge double door slowly opened inward. Xu Xin quickly hid to the side, fearing that something might come out of the door.
Behind the door, there was still a spacious corridor like a tunnel. The difference from the previous section of road was that the ground ahead was paved with alternating black and white bricks. Each brick was a square with a side length of about one meter. The whole road appeared to be covered with black and white grids.
"Trap?" Xu Xin expressed his guess.
"That's right." Chang Yin pointed at the two colored grids on the ground, "Each grid could be a trap, but it could also be safe."
Xue Lan also spoke up: "There are many types of traps, and it is basically impossible to predict which one it will be, so even if you are prepared, it is basically useless. The collaborator 24 years ago just ignored our advice and thought he had mastered all the traps. He insisted on moving forward recklessly, which allowed him to pass a long distance, but in the end he fell into a trap similar to a meat grinder, and the result..."
Xue Lan didn't say anything, but Xu Xin could imagine the scene at that time and couldn't help feeling a chill.
"What triggers this trap? Weight?" Xu Xin asked.
"If it were weight, it would be easy, but it doesn't seem to be. I used stones that were almost as heavy as humans and they couldn't trigger the trap. Maybe the condition is that it must have vitality." Chang Yin said.
"So... are you planning to use mutant beasts to step on the landmines?" Xu Xin guessed Chang Yin's idea.
"That's right." Chang Yin waved his hand and released a trembling mutant blood-marked wolf.
"Wouldn't it be better to release a few more?"
"Release more and let the trap kill several at once?" Chang Yin said unhappily, "I only brought more than ten, but it's enough. Most of the grids are safe, and only a small part will trigger the trap. Last time, only seven died and it was over."
This trap road really requires your life to be filled.
Xu Xin turned his head and saw the cheetah lying two meters away from him.
"You are not allowed to run around for a while. You can only step on the grids we have stepped on. Do you hear me?" Since there was no way to put it into the ring, Xu Xin could only warn it.
The cheetah looked at him and licked its fur, not knowing whether it understood or not.
"Okay, let's go. With its speed, it might be able to avoid it even if it steps on a trap." Chang Yin commanded the mutant blood-marked wolf to walk forward on a stone brick. It didn't step forward until it walked seven or eight meters before Chang Yin stepped onto the black and white stone bricks.
Just as Xu Xin was about to step forward, he was blocked by the stone statue of a maid.
"We can block the mechanisms for you in front. There will be some crossbow explosions and fire-breathing mechanisms with a large range. It will be dangerous for you to walk in front." The middle-aged maid statue suddenly spoke. She didn't say much along the way and had been looking after the little boy statue.
"Oh, okay, thank you." Xu Xin let the maid Xue Lan and the little boy go first.
The blood-marked wolf in the front seemed to be controlled by the long seal. It did not run around, but walked straight forward.
"Be careful, don't accidentally step on the stone bricks next to you and trigger traps like explosive crossbows. We don't care, but be careful not to hurt yourself." Xue Lan reminded Xu Xin.
The little boy statue, who originally liked to run around, now walked very obediently along the road that had been trampled by the wolf. He nodded vigorously when he heard Xue Lan's words: "Yes, yes, yes, uncle, you must not run around, it's scary!"
Maybe the previous person left a shadow on him.
"Okay, thank you." Xu Xin thanked them and followed the stone statues in front and stepped onto the stone bricks.
The moment he stepped on it, Xu Xin found that the stone brick was stepped down about half a centimeter, making a slight stone friction sound. He immediately tensed up: "What happened? How did I step on it?"
"It's all like this." The maid stepped on the brick in front of her, and that brick was also stepped on. "These mechanisms are of instantaneous and delayed types. The spike traps and meat grinders are instantaneous, and you will fall directly if you step on them. The delayed types are like this. You step on the brick and lift your foot, and the mechanism will be triggered."
As she spoke she moved forward a brick, which bounced upwards and returned to its original shape.
This is to make ordinary bricks have the same mechanism as trap bricks to paralyze the vigilance of passers-by. Xu Xin couldn't help but sigh that this trap road was indeed difficult to walk on, much more difficult than the trap Li Wenxi mentioned.
In the tunnel, the sound of the stone statues stepping on the ground and the sound of the tiles rising and falling kept echoing. Xu Xin looked behind him and found that the cheetah was walking behind him with a very standard cat step, moving forward along the path Xu Xin had walked.
Looking at the situation, instead of worrying about the cheetah, I should worry about whether I will fall to the side.
Suddenly, there was the sound of mechanical triggering and the miserable howling of wolves from the front.
The mechanism has been triggered!
Xu Xin looked sideways and found that the blood-veined wolf had disappeared. There was no brick at the original location of the blood-veined wolf. Chang Yin, who was originally seven or eight meters away from the blood-veined wolf, walked quickly forward, came to the trap brick, and stretched his head to look into the trap.
"How is it? What kind of trap is it?" Xu Xin asked from behind.
"Spike trap, the wolf is dead."
Chang Yin waved his hand again, and a blood-marked cat appeared. He stepped back a few steps, letting the cat bypass the triggered trap and continue forward.
