"It seems that the things outside were also frightened." Bai Chen said.

"Don't worry about this for now. You get out of the way. I'll try to break through this door!" Lu Tianyu asked Bai Chen and Kunlun to retreat a little, and then he continued to fire out the qi and refine the flames, trying to dissolve the door.

However, unexpectedly, this time his Qi refining flame did not work, and the door was not melted!

Even Lu Tianyu's Qi Refining Flame did not cause any damage to the gate.

At the same time, the "dongdongdongdong" sounded outside the door again, which was even more intense than before.

"There should be some monsters outside. I have already felt the aura of these monsters." Kunlun said.

Lu Tianyu also felt that the sound on the stone gate was indeed caused by the collision of monsters.

"How could there be monsters outside?" Bai Chen said curiously.

"I am more curious now. The meaning of these two secret rooms." Lu Tianyu was not curious about why there were monsters. He was more curious about what these two secret rooms were used for!

Judging from the current situation, these two secret rooms have played a role in protecting them. Otherwise, if the monsters outside rushed in, they would still be in some trouble.

But who would build two secret rooms like gabion here?

These two gabion-like secret rooms are so tightly sealed that even if those who enter here can escape the attacks of monsters, they will be trapped by this airtight secret room.

From this point of view, these two secret rooms did not seem to be built to protect monks.

Lu Tianyu couldn't help but look around again. Suddenly, he found a strange place in the secret room where he was staying!

On the wall of this secret room, he discovered a small formation!

"Formation?" Bai Chen was curious when he heard this. He looked in the direction Lu Tianyu pointed, and indeed, there was a palm-sized formation embedded on the wall!

Because the formation was too small and the aura emitted was too weak, Lu Tianyu and Bai Chen did not notice it at first.

Now, the existence of this formation is really strange!

The small one seems to be non-existent, the key is why a formation is arranged here!

"Can it be the mechanism to open the secret room?" Bai Chen said with a guess.

His words reminded Lu Tianyu that this may not be impossible.

Such a small formation seems to be able to only open the mechanism and use the trap.

"I'll try it!" Bai Chen said, and walked to the formation. After a while, he cast a forbidden talisman on the formation.

"Crack!" A crisp sound sounded, as if some mechanism had been opened, and the small formation was also opened, and then a rumbling sound came from above the head.

Lu Tianyu and Bai Chen all looked at each other, and saw the stone wall above their heads open and a ray of light shot down.

"Yinyang Mountain!" Lu Tianyu saw that the light was shooting down from Yinyang Mountain!

In other words, above the secret room is the Yin-Yang Mountain.

"Did we fall from above?" Bai Chen said happily.

Lu Tianyu did not answer, but looked at another secret room and said, "This secret room should also have a formation!"

Bai Chen immediately searched around the wall. As expected, he found two small formations in the corner of the wall.

"How could it be two formations?" Bai Chen was puzzled. There was only one formation in the secret room of Lu Tianyu, and there were two formations in the secret room where he was located?

One of the formations must have opened the stone wall above the head, what about the other formation?

"The other formation should be to open this door!" Lu Tianyu looked at the closed stone door. The sound of thundering outside the stone door became more and more intense, as if something was rushing in urgently.

Lu Tianyu continued: "The two formations must be chosen to open the correct ones, otherwise we may put a group of monsters in it!"

Bai Chen naturally knew this, so he used his innate magical power to carefully feel the two formations.

However, these two formations are essentially the same formation, both of which are to open the mechanism. Therefore, even if he has the talented magical powers, he cannot tell which formation opens the gate and which formation opens the stone wall above his head.

"What should I do?" Bai Chen looked at Lu Tianyu.

Lu Tianyu thought for a while and said, "Everything is open, we'll just go up from another secret room!"

"Everything is opened? Senior wants to put these monsters in?" Bai Chen was surprised.

Lu Tianyu nodded: "I want to see what's going on!"

"I understand! Senior Lu, you and Senior Loulan, Senior Kunlun will go up first!" Bai Chen said to Lu Tianyu.

"Goddess and Kunlun go up first, I'll stay here!" Once the door is opened, countless monsters will inevitably rush in. Lu Tianyu is afraid that Bai Chen will not be able to deal with it, so he plans to stay here.

"Master, I'll stay to protect you!" Kunlun said.

"No, just protect the goddess! Hurry up!" Lu Tianyu's tone was firm, and Kunlun had no choice but to look at Queen Loulan.

Queen Loulan didn't say anything, just asked Lu Tianyu to protect herself, and then flew directly to the secret room.

"Master, this place is indeed Yin-Yang Mountain, but it is not the place where we came down." After Kunlun came up, he subconsciously looked around and found that although this place was the area of ​​Yin-Yang Mountain, it was not the place where they came down.

On the contrary, it seems like it is in the Yin and Yang Mountains, surrounded by towering and tall peaks!

The burning sensation became even stronger, and Kunlun couldn't bear it.

Seeing this, Lu Tianyu said to Bai Chen: "Let's go up and take a look first!"

Bai Chen agreed, and the two of them flew up as well.

"This place seems to be in Yin and Yang Mountain, and the scorching aura around it is so strong!" Bai Chen looked around and said.

"This is indeed the core area of ​​Yin and Yang Mountain. Look at it, there are so many human bones!" Lu Tianyu said.

When a few people looked over, they saw countless bones scattered on the flat ground in front of them, most of them belonging to humans, and a small number of them belonging to monsters. Roughly speaking, there are at least tens of thousands of them!

In other words, there are at least tens of thousands of human races and monsters dying here!

Most of them are human race!

"How come so many people die here? Could it be that there has been any war here?" Bai Chen was curious.

If he had to say that the total number of people who died in the Yin-Yang Mountain was more than 100,000, he didn't think anything was there, but there were more than 100,000 corpses in this place alone, and he felt something was wrong.

How could hundreds of thousands of people die in the same place?

Yin and Yang Mountain is not a battlefield, and those who come here to experience will not lead the entire sect...

"These corpses did not die here at the same time, but were brought here!" Lu Tianyu walked over and checked for a while and said.

"Come on?" Bai Chen was curious.

"Not bad! Look at the teeth marks on these corpses, they should be caused by some kind of monster biting. I think these people died in other places and were brought here." Lu Tianyu said.

"But they don't seem to be killed by monsters!" Kunlun was curious.

Judging from the injuries on these corpses, they should have been killed by powerful combat power. Only a few corpses were bitten by monsters, but they were also killed by monsters after being seriously injured by powerful combat power.

"These people have different deaths, some are bitten to death by monsters, and some are poisoned to death..."

"Being poisoned to death?" Bai Chen was curious.

"The elder of Tianzong Gate was also poisoned to death!" Queen Loulan walked over.

Previously, they found a corpse of the elder of Tianzongmen on the way up the mountain, and Lu Tianyu also said that he was poisoned to death.

Now there are people who have been poisoned to death among these corpses. Could it be that there is a mechanism trap here that specifically releases venom?

"It may not be impossible!" Lu Tianyu said in a pondering mood: "Yinyang Mountain is extremely dangerous. I don't think it is strange that there is a mechanism trap that can release venom... I am still curious about why these corpses were brought here."

Lu Tianyu looked at the corpses with confusion.

Why were these corpses brought here and what was the purpose?

"Roar!" At this moment, a huge beast roar suddenly came. Lu Tianyu and his men hurriedly ran down the upper direction of the secret room and looked down. They saw that the stone door was shaking and was about to be pushed open, and the sound of beast roars also came out of the crack of the door.

"It seems that we don't need to open the formation. These monsters can rush in by themselves." Bai Chen said with a wry smile.

"How could this happen?" Lu Tianyu frowned, with a confused look on his face.

"What's wrong with it, is there anything wrong?" Bai Chen didn't understand what Lu Tianyu said.

"There are no bones in the two secret rooms where we are, which means no one died here. Perhaps, we are the first people to fall, but no matter what, it proves one thing. The monsters outside the secret room have never rushed in! Moreover, Kunlun had just tried that with her power, it was impossible to open the stone gate. Why are these monsters now showing signs of breaking through the stone gate? Could it be that the monsters outside the stone gate are even stronger than Kunpeng?" Lu Tianyu was curious.

Kunpeng is an evil beast, and its strength is naturally unquestionable!

Theoretically, unless it is a snake dragon or a monster of the same bloodline, it is possible that it is comparable to Kunpeng in terms of strength.

But although Yin and Yang Mountain is big, there may not be many evil beasts!

Otherwise, Luoniao Town would not have been calm for so many years, and those ordinary monks would not have been able to enter and exit Yin and Yang Mountain safely!

This is enough to show that even if there are evil beasts in Yin and Yang Mountain, there will not be too many!

Since there is no evil beast that surpasses Kunpeng's power, why can it break through this stone gate that Kunpeng cannot break?

"Perhaps, there are many monsters outside!" Kunpeng said.

"Can you feel that there are many monsters outside?" Lu Tianyu asked.

"Not many! There are at least thousands of people, and their strength is not weak." Kunpeng said in a deep thought.

"Then do you think these monsters are coming for us?" Lu Tianyu continued to ask.
