The exit has been sealed, and only by going on can the two of them have any hope of getting out alive, and no one can find them here, let alone save them. Pen, fun, and www.biquge.info

This boulder was not placed artificially, it should be controlled by the organs.

Yang Xiaofeng recalled what they did when they entered the cave, and what triggered the mechanism in the cave, you must know that they are now going deeper into the cave, who knows if there is a more powerful mechanism than this in front, this mechanism has not directly asked for people's lives, in case there is a mechanism in front of them that asks for people's lives, the two of them are stupid and don't know what they touched to trigger the mechanism, and the two of them died too unjustly.

After the two entered the cave, the only thing they encountered was the bones of an unknown creature that had existed for an unknown number of years.

Could it be that the problem is with the skeleton?

Yang Xiaofeng told Lin Ya what he thought. Lin Ya also agreed with Yang Xiaofeng to figure out why a boulder suddenly fell and sealed the entrance to the cave, whether it was man-made or caused by a mechanism.

On the way back, the two of them carefully looked at the ground, and if there was a mechanism, the ground was more likely. Before they knew it, the two men were back next to the skeleton again.

Yang Xiaofeng walked over and carefully checked what was different about this skeleton, but to his disappointment, this was the skeleton left behind after the death of a creature, and there was no difference.

What's the problem?

By the way, there is also the wall, Lin Ya touched the wall. That was just now when Yang Xiaofeng made Lin Ya crash against the wall in order to avoid danger.

"Lin Ya, did you feel anything abnormal when you hit the wall just now?" Yang Xiaofeng decided to ask the person concerned.

"Anomaly?" Lin Ya thought slightly, "It seems that there is something abnormal." ”

"Oh, tell me about it."

"I bumped into a bumpy hard object, but it suddenly became a dent. I didn't pay much attention to it at the time. Lin Ya told Yang Xiaofeng the truth about what she had just encountered.

"I guess the mechanism is on the stone wall."

"Why didn't we feel it when the boulder fell? It's like a god suddenly appearing out of nowhere. Lin Ya said the question in her heart.

"That's because, when the boulder fell, it was when the serpent passed by us, the serpent was so close to us, and it walked loudly, and when we were focusing on the serpent, the boulder fell, and we didn't feel it." Yang Xiaofeng told his guess.

Lin Ya nodded as if she didn't understand.

"Alright, let's move on! But we have to be careful, careful, careful, and preferably not touching anything else. Yang Xiaofeng advised.

Lin Ya also understands the reason for this.

The two walked past the skeleton found at the beginning, walked forward for about ten meters, and the scene in front of them once again made their heartbeat involuntarily accelerate, and it was another beast skeleton, just looking at the size of the previous one.

Yang Xiaofeng carefully observed whether there was a hidden mechanism in this skeleton, and after making sure that there was not, Yang Xiaofeng picked up a bone again and blasted at it with all his strength, just like the last time, the skeleton was intact, without the slightest trace of destruction.

Such powerful creatures have all died here, so how strong is the real creature in the cave, and is it still alive now?

The two of them are really in a dilemma now, enter, there may be powerful unknown creatures in front of them, and it is hard to say whether they can survive or not; Retreat, the back has been sealed, although they can survive for some time, but they can't escape the fate of death after all.

Even though the two of them were terrified in their hearts, they still had to move forward. In the front, there is still the possibility of survival, and in the back, there is no doubt about death.

After walking past the second set of bones, the two of them walked more than ten meters and encountered another pair of bones.

Lin Ya grabbed Yang Xiaofeng's arm and was terrified.

Yang Xiaofeng can't be messy, he must be calm. Even Yang Xiaofeng's heart is galloping now, and he is not calm, but he can't show it, otherwise he hasn't seen the true face of the master in the cave, and the two of them will be defeated without a fight because of their psychological breakdown.

Besides, he had already seen two huge skeletons, and Yang Xiaofeng was a little immune.

Yang Xiaofeng comforted Lin Ya and continued to walk forward.

After walking for I don't know how many meters, they saw as many as thirty-six pairs of beast bones, and each skeleton was about ten meters away from each other.

Is this the burial ground of beasts? Otherwise, how could there be so many bones?

After walking forward for an unknown number of meters, the two of them did not see a single skeleton, and when they thought that there were no more animal bones, the scene in front of them stunned them again.

I didn't know how many pairs of bones were piled together, no, there was a pair of bones wrapped in this thin layer of animal skin, and the two looked closely, it turned out to be the giant snake just now.

At this moment, only a pair of bones and a body of snake skin were left on the snake's body, and the giant snake that had chased and killed the two alive before had become one of the many bones in this cave at this moment.

Looking at the appearance of the giant snake, it seems that it has been drained of the essence blood of its whole body and died. Moreover, Yang Xiaofeng also found that this pile of bones was only piled up in a specific range.

"This area can't be a formation, right? A formation for refining the essence and blood of living beings. Yang Xiaofeng thought of this, and cold sweat broke out.

As soon as he had this thought, there was a flash of red light in the area.

"The formation has been activated? I just died? Little X, I'm sorry! ”

Fortunately, before this, Yang Xiaofeng did not let Lin Ya step into this area, otherwise both of them would have died here.

But after waiting for a long time, Yang Xiaofeng didn't feel any discomfort.

"Damn! Bluff me? I'm scared to death! However, fortunately it was bluffed me, otherwise my life would not have been guaranteed! ”

"What's wrong?" Lin Ya saw Yang Xiaofeng standing motionless, and thought something had happened to him.

"It's fine!" Obviously, Lin Ya didn't see the red light just now; And Yang Xiaofeng didn't plan to tell Lin Ya what happened just now, anyway, it was fine, and saying it would only increase Lin Ya's mental burden.

"Let's go!" Yang Xiaofeng walked in front. Lin Ya followed.

The next road surprised them.

As they walked, suddenly, a fire broke out on both sides of the road ahead, but the color of the flame was dark blue, adding a strange color to the unknown cave.

The stone walls on both sides are no longer uneven and moss-over, but smooth and flat, apparently specially trimmed.

Moreover, there are murals on the walls.
