Walking to the trap where the blood-striped wolf was killed, Xu Xin took one look inside and then averted his eyes.

...a little disgusting.

This trap was a bit too cruel. He thought it was the kind of trap that stabs upward, but he didn't expect that it stabbed out from all directions, directly turning the blood-striped wolf into a honeycomb.

The passage was very long. By letting the mutant beasts step on the trap, after eight mutant beasts died, Xu Xin finally saw the second door not far away.

Along the way, in addition to the initial spike traps, we also encountered a series of traps such as crossbow traps, high-temperature fire-breathing traps, abyss traps, and explosion traps. Those mutated beasts that led the way did not have a good end, and they all died miserably.

In a trap.

These traps are not as simple as imagined. The crossbow trap is where countless crossbow arrows are shot out from the walls around the stone brick, including the ceiling, covering a large area. There is nowhere to hide, even the nearest long

Yindu was hit by the fish pond, but fortunately those crossbow arrows did no harm to him.

Xu Xin conveniently put all the crossbow arrows he could pick up along the way into his backpack.

The high-temperature fire-breathing trap spits out fierce flames from the ground, and not just the trap brick, but all the surrounding bricks within a 5*5 range spew fire. It is impossible to dodge at all. The beast leading the way instantly turns into a fire-breathing trap.

Ash.

The abyss trap is like a crack in the ground in a maze. It is extremely dark and deep when you look down. After stepping on the trap brick, the stone bricks in a 5*5 area around it disappear directly, and the mutated beast directly falls into the bottomless abyss wailing.

.

The explosion trap is very simple. Not only the explosion range is amazing, but the huge explosion makes Xu Xin's ears temporarily deaf. The fire blooms in front of his eyes, making Xu Xin's eyes accustomed to darkness unable to see anything in an instant. Countless.

The gravel fragments were scattered in all directions, like a huge fragmentation grenade thrown in the tunnel. If it were not blocked by the stone statues in front, he might have died immediately.

Finally, after going through many hardships, they finally walked out of the black and white floor tiles and were not far from the second door.

"There's no danger anymore. You don't need to be so nervous." Changyin took back the beast leading the way.

"Are you sure? It's better to let the beast lead the way to the door." Xu Xin was very cautious. Those traps were really scary. If you weren't careful, you wouldn't even know how you would die.

"The trap road has been passed, and the ground cannot be stepped on anymore." Changyin stepped on the smooth ground, "Don't worry, it's okay, I will lead the way."

While heading towards the second door, Chang Yin told the story of the second group of survivors who came to the dungeon. Although Chang Yin did not help the second group of survivors, he followed behind and observed them.

He told Xu Xin that there were nearly thirty people in the group of survivors, which was a large number, but in the end they all died on this trap road.

If a small number of people are willing to sacrifice themselves, then most people can go this way, but due to human nature, no one is willing to sacrifice themselves for others. Not only did they not cooperate, they even started fighting among themselves. The most powerful person in the team

Forcing weak people to explore the trap ahead, others not only failed to stop it, but even contributed to it.

In the end, after several people died, the last person who was "selected" and forced to explore the path was driven crazy, running around like crazy, wanting to die with everyone, and triggered an explosion mechanism in the crowd.

Not to mention the survivors who were hit by the bombing, those survivors who were following behind and were not hit by the bombing were also stabbed to death and injured by countless fragments produced by the explosion. In the end, this group of survivors was completely wiped out and all died.

On this trap road.

Xu Xin was silent. There is actually no suspense about this result. People are selfish. Unless they have a sense of mission for their loved ones or a special profession, it is impossible for most people to do it for someone who is not a relative or a friend.

Those who sacrificed their lives.

After the story was told, they all came to the second door. Xu Xin pushed gently from behind and the door slowly opened.

The scene behind the door stunned Xu Xin. It was still an upward tunnel. The walls and upper walls of the tunnel were made of stone, but the ground turned into soil. Yes, it was soil. He was actually looking in this underground city.

to the soil.

"You survivors are really amazing. What kind of power is this?" Although Changyin has seen it many times, he is still amazed every time. The door that he could not push at all was opened by Xu Xin with a gentle push.

.

"It's not as magical as you. Okay, tell me what's behind the second door. Aren't you just stuck in front of the third door?" Xu Xin looked at the soil and activated her identification ability.

He was surprised to find that the soil was not contaminated soil, but normal soil with good quality.

A green light appeared in his eyes, and there were even a few blue light spots.

"Fertile soil!" Xu Xin's eyes jumped. There is fertile soil here (blue)!

Fortunately he brought the shovel out!

"There's something strange behind this door. When we came here last time, the last section of the road couldn't be walked at all." Changyin was a little helpless, "The front is still normal, but there are some mutated plants, like vines, among the piranha flowers.

It's nothing to us if something like that comes out to attack, but the last few dozen meters are very strange."

Are there mutated underground creatures? Xu Xin suddenly thought of something and started looking at the map in his mind.

"The last few dozen meters can't be called mutated plants at all. They are called mutated monsters. They are all mutated creatures above the intermediate level, and some even reach advanced levels. You must know that even we can barely protect ourselves from the advanced mutated beasts.

It's impossible to take that survivor to the next door." Chang Yin said more and more helplessly, "Isn't this damn place just not letting us out?"

After looking at the map, Xu Xin felt slightly relieved.

He had a guess as to why the last few dozen meters were so difficult for the survivor to walk.

The area where Xu Xin is now is already outside the three-kilometer range, and more than half of the previous trap road was outside the three-kilometer range.

If his protection range is the same as that of others, I am afraid that powerful underground monsters will emerge from the ground when they step on this soil.

The location of the survivor's treehouse is different from his, but it's almost the same. They are all within this area. I'm afraid the last few dozen meters are outside the protection range of his treehouse, that's why there are so many

A difficult monster to deal with.

"Anyway, let's give it a try first." Xu Xin put on the armor in his backpack, took out his spear, stepped into the door, and stepped on the soil.

This section of the road is not very long. At a glance, the gate in front is only more than 200 meters away from Xu Xin.

There are no plants planted on this soil. After all, it is underground. Without sunlight, most plants cannot grow at all.

Coco on the shoulder woke up at this time. She lay on Xu Xin's shoulder and rubbed her eyes.

"Hey!" Suddenly, Coco yelled and poked Xu Xin's face.

Xu Xin knew that this was the cry of approaching danger. He stepped back, and a vine as thick as an arm covered with red thorns came out from his original position. Xu Xin, who had long thought of it, stabbed it directly.

, the spear tip directly penetrated the vine.

The vine pierced by Xu Xin struggled for a moment, then suddenly became brittle and shattered on the ground.

Just like the situation on the ground, within the protection range of the tree house, even underground, those who want to attack the protection of the tree house will have to pay the price with their lives.

"Yes, that's it. It was like this last time. It broke when it came out, but the last few dozen meters were impossible to walk." A vine also appeared under Changyin's feet. He stretched out his hand and easily pulled out the vine with both hands.

As soon as he pulled it, the vine was instantly torn into two pieces.

Xu Xin looked at the cheetah following behind him and pointed forward: "You go up front and deal with these mutated plants."

The mutated cheetah that had been behind him didn't refuse when he heard Xu Xin's words. He kicked his legs and quickly rushed to the front, running forward quickly. Behind him, various mutated vines and flowers emerged from the soil.

.

But the cheetah's speed was so fast that when these mutated plants emerged, the cheetah had already run ahead.

"Hey!" Coco was startled by the cheetah's speed.

As the fastest running animal, it only took less than ten seconds to run to the door two hundred meters away. Behind it, a row of mutated plants were disturbed by it and emerged from the ground. They could not find it.

When it reaches the target of attack, it can only spin in place.

Xu Xin couldn't help laughing when he saw this situation. Before he could make any move, the cheetah started running back again.

These mutated plants began to attack the cheetah, but the cheetah was too fast, too agile, and avoided all the attacks. It returned to Xu Xin's side after more than ten seconds.

"Well done!" Xu Xin praised.

The cheetah raised its head proudly and lay back behind Xu Xin again.

Xu Xin looked forward, and he found that the plants that had attacked the cheetah were still maintaining their attacking movements, just like the copper treasure chest vines that attacked Xu Xin during the jungle exploration activity.

"Turn into onion rings?" Xu Xin took out his crossbow and fired at the nearest mutated plant.

The crossbow arrow hit the stem of this huge Venus flytrap with great accuracy. With a click, the stem as thick as an arm broke directly, and the huge leaves used for hunting fell to the ground and broke into several pieces.

"Is this... solved? How come there are no high-level mutant monsters near the door? Is this different from last time?" Chang Yin's voice was full of surprise and a slightly trembling joy.

Xu Xin fired again and hit a vine in the distance. As a result, the vine also shattered directly.

"Little leopard, you go for a run again." Xu Xin said to the cheetah behind him.

The mutated cheetah was dissatisfied with the title of "little leopard" and barked, but still followed Xu Xin's instructions and ran back and forth.

This time, only a few mutated plants came out, and they were scratched to pieces by the cheetah's claws on the spot.

"It seems there is no danger, let's go." Xu Xin smiled. This third level was a piece of cake for him.

"This..." Changyin's family looked at each other, confused, but still followed Xu Xin forward.

Passing by those mutated plants that had become completely brittle, Xu Xin chopped them all into pieces with his iron sword. It was still necessary to hit them again, just in case they were alive again.

Relying on his identification ability, Xu Xin shoveled out two pieces of fertile soil (blue) in the entire area and put them into his backpack. Unexpectedly, the underground city also had soil resources, which was an unexpected surprise.
