The two of them continued to move forward, and the Devil's City was already in sight. It can be seen that there are several sections of half-collapsed walls on top of the mountain wall. No section of the wall is complete. Either collapsed or notched.

As the two approached the cliff, there was another whining sound in their ears, and because of their previous experience, they didn't care about the wind except to observe everything around them.

At this time, the two of them smelled a foul smell.

Go up the cliff, in fact, this cliff has a road leading to the castle halfway up the mountain. Sometimes it's a path, sometimes it's a stone step, and sometimes it's blocked by a collapsed sand or earth wall.

In these paths, stone steps, and collapsed earthen walls, there were corpses every two steps, some with large swords inserted into the bones, some with short swords, and some with sharp arrows.

Some of them were placed in the direction of the road, and some were placed horizontally in the middle of the road.

Some are white, some are black, some have only skulls, and some have only limb bones.

Some of the bones still had a little carrion remaining. The stench you smell below is supposed to be from the bones and Thursday's sand.

But there is still a way to go. The two walked halfway up the mountain from the bottom of the cliff to half an hour.

Halfway up the mountain, there are several broken beams in front of them, and the two of them step on the broken beams, which are some twisted and compass-like passages, and people seem to have entered a mysterious palace.

It used to be really a palace, and the roads inside were very smooth, and some of them were stone roads.

The two were afraid of being ambushed, so they fought with their swords. The further you go, the more complicated the road becomes. They found that the road here was to go into the mountains.

Now several caves have appeared in front of me. From all the way to the cave, such bones accompanied them.

The further you go to the cave, the more bones there are. The two of them marched forward in fear.

In the cave, you can feel the different temperatures and demeanors.

I didn't enter the cave, but it was still sunny outside, and my body was still warm. As soon as you enter the cave, there is a ghostly aura inside, and there is a yin qi lingering around you. There is an indescribable fear.

The two of them stayed at the door of the cave for a few minutes, allowing themselves to get used to the different reactions inside and out.

"Bring all your weapons and flint with you. We need to be prepared. ”

Shen Feiyang said to Mo Xingxing.

Mo Xingxing took out the flint from his arms, and Shen Feiyang had already found two large handfuls of hay from outside the cave and tied them into two torches.

The two of them, one with a torch in one hand and a sword in the other, cautiously entered the cave.

The caves here are high and low, large and small. Some are dry, some are wet. The two of them looked and couldn't find which one was the best way to get in and out, because there was no way to get in and out.

Shen Feiyang saw that the middle passage was drier and more spacious, but this passage had the most bones on it. It can be seen that the more people go up this passage.

He waved his hand to Mo Xing, and the two of them groped their way through the widest passage in the middle.

Twenty meters into the passage, a door frame appeared, only two stone pillars, no door panels. The door frame is about one meter, and the passage is about two meters.

There were especially many bones outside this door frame, and the two of them did not count them, but there were no less than twenty or thirty bodies.

It's just that the bones have been cleaned up and piled up outside the door frame, and the passage in the middle is still very redundant.

On the left pillar there is a column of words "Birth and Death".

"What do you mean?"

Mo Xingxing asked in a low voice.

"What do you mean?"

Mo Xingxing asked in a low voice.

What does it mean, I think it is the simplest meaning, enter and die, and come out and live. In short, no one is allowed to enter. ”

"Then Shen Daxia, do we still want to go in?"

Mo Xingxing took a step back and said to Shen Feiyang.

Shen Feiyang glanced back at Mo Xingxing, and a look of disdain suddenly appeared in his heart, but it was only for a moment. Because, Shen Feiyang knew that if there was an internal problem at this time, it might be more dangerous than a powerful enemy.

Shen Feiyang glanced inward twice, and a sudden pride arose in his heart, and he said to Mo Xingxing:

"It's Longtan Tiger's Den, let's break into it. Mo Daxia, you step back, two steps away from me, if there is any situation, it is easy to dodge. I'll go to the cave and look at it. ”

The passage turns left at the beginning.

Shen Feiyang walked to the doorpost with the words "birth and death", stretched out his head to look to the left, and when he saw it, he was startled.

There was a skeleton about three steps into the door.

I don't know how long it took, but the one on the left was only a pile of skeletons, with its head lying on the side of the doorway, and the two thigh bones facing inward.

The skull is face up, the top of the head is outward, and there are two arrows stuck in the chest bones, and one arrow under the skeleton.

The one on the right is similar to the one on the left, and the thigh bone is also in it, but the one on the right is a skull with the right hand side to it. Three arrows came out of the chest, and the arrows were horizontal, apparently from the back.

Judging from the direction of the bones, one person on the left is falling backwards, and one person on the right is throwing himself forward.

Two or three steps into the cave is a sandy floor, and a lot of weeds have grown. Some of them are dry, and at the foot of the door, some small grasses sneak out of the ground, which is extremely inappropriate for this environment.

Dead bodies on one side and green on the other. It's easy to think to two extremes.

He looked further in, and saw that the underground passage was paved with many stone slabs. There is more sand and dust on the outer pieces, and there is less sand and dust on the stone slabs inside, and there are rare words on them, but the light is not good, and the distance is far, so he can't see clearly.

He looked inside, and the passage turned to the right about ten meters later, in the shape of a curved ruler.

When you turn right, you see a black hole.

He had to retreat first.

Mo was happy to see Shen Feiyang retreat, and before he approached the door, he also turned around and walked out, and asked:

"What's the situation, Shen Daxia? I haven't entered it yet, I can't see it. ”

"There are two corpses in that door, and both of them have three arrows on them, and I am thinking that these two corpses must have been hit by the mechanism of this gate or passage, and we must be careful. ”

"I'll go in and have a look, too. ”

Mo was happy to hear that there were bones inside, and there were three arrows on it, and he also wanted to see it.

"You just go outside the door and take a look at it twice, I want to think about it, and you come out and think about it, what's going on. ”

Shen Feiyang was afraid that something would happen to him, so he reminded him first.

Mo Xingxing tiptoed to the door, stretched out the fire fold in his hand, and as soon as he probed, he shrank back in fright, and the fire fold in his hand almost fell to the ground.

He made up his mind and looked inside. Shen Feiyang just saw this just now, there will be no problem, as long as you don't go in.

He looked at it for a while, and then came out and told him about the condition and location of the bones.

"What do you see?"

Shen Feiyang saw him retreat and asked.

"I think the guy on the left went in first, and the arrow hit him right in the chest, and he didn't have time to step back, and I don't know if he jumped backwards or was hit by the impact of the arrow.

As for the man on the right, he should have heard the sound of an arrow or saw something happen to his companion, and he reflexively ran out, and the arrow hit him in the back. ”

Shen Feiyang saw that his analysis was very reasonable, nodded after listening to him, and then added:

"I don't think those two bones have been poisoned. Whether it's on the wall or on the ground, I can't say for sure. What do you see?"

"I also think it's not on the ground, it's on the wall. Shen Daxia, how did you find out that the bones were not poisoned?"

Mo asked happily.

"If the corpse is poisoned, then his bones will turn black. The deeper the poisoning, the larger the area of blackened bones, and vice versa, the less.

But I saw no signs of blackening on the bones of the two bodies, so I judged that he was not poisoned.

The cause of death was that these three arrows passed through the chest. Now we just need to find out where this organ is and what the rules are. Everyone thinks about it. ”

Mo was happy to listen to Shen Feiyang's analysis, and he was ashamed.

He was also nervously thinking about the mechanism of this door.

Shen Feiyang was silent and thought for a while, then he stood up again and walked to the door to observe again.

After a while, he withdrew, and Mo Xing looked up at him to see what arrangements he had arranged.

"You and I each light a fire fold, and we don't need to bring weapons. As long as you figure out the mechanism, the weapon is useless. If you don't figure out the mechanism, the weapon won't be able to help. Let's look at the handwriting on the floor and on the wall. ”

The two of them stood up, sheathed their swords, and slowly walked to the door with the fire fold in their left hand. First, fold the fire in your hand and stretch it into two feet.

When there was no reaction to the fire fold, Shen Feiyang said:

"The air in this cave is normal, and there is enough oxygen. I swept the sand off the slate and saw what was written on it. ”

He moved the fire fold of his left hand to the left, and then said to Mo Xingxing behind him:

"You take two steps back. ”

Mo Xingxing took two steps back as he said. However, he still folded the fire forward and gave Shen Feiyang a little more light.

Shen Feiyang raised his right palm lightly, and slowly pushed towards the first stone slab three steps ago, but without seeing him exert himself, the sand and dust on the stone slab flew away as if someone was cleaning it.

At this time, I was able to see the words on it clearly, and looking forward, the first and second stone slabs were a word "death", and the third stone slab was a word "life".

At this time, Shen Feiyang waved his palm at the fourth and fifth stone slabs, and the words on them were clearer.

Because there is less sand and dust on it, and these stone slabs are all one-meter-square stone slabs, and the words on them are all one-foot-square characters, and they are hewn with steel chisels, one finger deep, but not difficult to identify.

The fourth and fifth blocks have the word "death" on them, and they can't be seen clearly in the future. Mo was happy to see that the cave was dusty, and Shen Feiyang didn't have an accident, he approached again, leaning on his right head and looking in.

"You see it. That death is two stone slabs, there is only one stone slab for life, and from the distance, there are few chances of life and many chances of death, and the time of death is long, and the time of life is short. Let's try it first. You lean aside. ”

Shen Feiyang pointed to the words on the stone slab and said to Mo Xingxing.

He handed Mo Xingxing the fire fold in his left hand, pulled out the sword from behind his back with his right hand, picked up a small stone from the ground with his left hand, and threw it at the stone slab with the word "death" written on it three steps ago.

As soon as the small stone hit the stone slab, I heard a "pop", and the three sounds of "snort" sounded almost simultaneously, and three sharp arrows shot out from a waist-high position on the stone wall in front of them.

These three sharp arrows were not blocked all the way, and almost at the same time, they shot at the right stone wall of the two of them with a "ding", knocking off a layer of lime on the stone wall, and shooting the stones on the stone wall with a white mark.

The two of them were dumbfounded, but fortunately they didn't rush in just now, otherwise they would be lying there straight like the two corpses.
