Seeing his sister's appearance, Li Yuncong thought that her strange illness had flareed up again, and he didn't dare to stay here at the moment:

"Brother Mu, are you staying? or are you going to leave with us?"

Ye Nan's eyes flashed, and he said, "I still want to stay here for a while, even if Brother Li leaves first, I will go to the Netherworld Pool to find you!"

"Okay, but Brother Mu is better to be careful, I always feel that this stone house is a little evil!"

Li Yuncong had already told Ye Nan the specific location of the Netherworld Pool before, and after saying it to him at this moment, he took Li Xiaojing down the mountain.

Ye Nan looked at the stone house quietly, and a strange color flashed in his eyes.

Originally, he was not interested in whether there was a treasure in this stone house, he just wanted to collect the Yan Po grass as soon as possible, and then wait for the tenth day of prohibition to open and leave as soon as possible.

But at the moment when the door of the grimace room opened, he felt a trace of summoning power coming from inside this house, and the object of that summoning power turned out to be the internal space formed by refining the starry sky stone!

"What does this stone house have to do with that starry sky stone?" Ye Nan frowned, he now felt that the summoning power of that stone house was getting stronger and stronger, and it seemed to have a hint of extreme fanaticism.

"Anyway, there are still a few days before the ban in the Demon Valley is opened again, so it doesn't hurt to go in and take a look!"

The white mist prohibition outside the Demon Valley was only open during the first and tenth days, and now it was the second day they entered, and the prohibition had already been closed, even if Ye Nan had collected Yan Po grass now, he would not be able to leave the Demon Valley.

After making a decision in his heart, Ye Nan no longer hesitated, and stepped into the stone house with a slight movement of his footsteps.

Squeak quack!

The moment Ye Nan stepped in, the door of the grimace room closed instantly, and its speed was so fast that Ye Nan didn't even react.

"Huh?"

Ye Nan's brows furrowed tighter and tighter, and he pulled the door with his hand, but he didn't move.

Seeing that the back road was broken, Ye Nan's face was slightly gloomy, and his eyes could only sweep towards the room.

The house was pitch black, and he couldn't see his five fingers, Ye Nan focused his spiritual power on his eyes at the moment, but he could see the situation here clearly.

The house is only a few tens of zhang in size, and there is nothing in it, except for a pitch-black hole in the very center of the ground. The entrance of the cave can accommodate three people to pass through at the same time, and the stairs lead straight to the bottom, presumably the people who came in before have already gone down.

"Huh?"

Ye Nan just wanted to go down, but suddenly his eyes turned and locked on the wall inside the house.

The walls are covered with carved patterns, each of which depicts a grimace. They stand or sit, smile, or breathe.

But every time it falls in the eyes, it will make people feel cold and gloomy.

"Why do I feel soul fluctuations on this pattern?" Ye Nan rubbed his chin with his palm, and the essence in his eyes flickered.

After checking for a moment and finding no abnormality, Ye Nan could only walk slowly into the hole.

And just after Ye Nan left, he saw that the patterns in the house came to life one by one, and streams of black gas burst out from the pattern, flying around the house.

Swish!

At this moment, Ye Nan's figure, who had already walked into the hole, rushed out.

Ye Nan's speed was fast, but what was unimaginable was that the black qi was faster, and the moment before it rushed up, it was all hidden in the pattern.

"Huh?" Ye Nan noticed the abnormality before, so he killed a horse gun, and at this moment, he looked at the quiet inside the house, and the light in his eyes flashed.

After seeing that there was no abnormality, Ye Nan could only shake his head and walk down again.

This time, after Ye Nan left, there was silence in the house, and after half a sound, a stream of black gas came out again.

The black qi slowly solidified, and two inky black figures appeared at the back. Both of these figures had grimaces, but one was smiling and the other was angry. At this moment, the two looked at each other, and they both showed a look of palpitation.

"This human is so cunning that he almost found out!"

"Well, this guy's mind is really sharp, so many people have entered before, including a girl who has turned a star, and they haven't noticed anything abnormal, only this guy has been cautious from the moment he enters the door!"

"Do you feel the breath on this guy's body, is it the thing from my clan?"

"I can't be sure! After all, that thing has been lost for too long, and now it's just a legend!"

The two grimace figures whispered and talked for a moment at this moment, and then in a flash, they all turned into billowing black gas, and disappeared into the wall pattern again.

Ye Nan didn't know what was happening here, and at this moment he was slowly walking in a corridor.

There were also many grimace patterns on the walls of the corridor, and Ye Nan walked slowly while observing carefully, as he didn't seem to be in a hurry.

This corridor was only 100 meters long, and after a while, Ye Nan had already reached the end, but the scene at the end made him slightly stunned.

In front of me was a black hall, with a grimace sculpture in the center of the hall, and the ground was full of white bones.

Under these white bones, there are hundreds of corpses, each of them has a weapon in their hands, and it seems that they are fighting each other and dying together.

And at this moment, the many scattered cultivators were like crazy, snatching the weapons in the hands of the white bones one after another, fanatical and greedy.

The "Spirit Weapon !!" felt the fluctuations of those weapons, and Ye Nan's pupils suddenly constricted.

There are no less than hundreds of these weapons, and there are dozens of them with spirit pattern fluctuations. Many scattered cultivators desperately snatched these spiritual weapons, and the battles were very fierce.

"That's not right!" Ye Nan stood still, and after careful observation, his complexion changed instantly.

Ye Nan himself was extremely sensitive to metal energy sensing, but at this moment, these weapons made him not have the slightest sense!

In other words, these are not spiritual weapons at all! or discarded spiritual weapons that have no value at all!

"And the reason why there are spiritual pattern fluctuations is because there are ...... in it Soul !!"

There is only one possibility for a soul that can inhabit a weapon, and that is ...... Demon!!!

Thinking of this, Ye Nan's face was extremely ugly, and as soon as his body turned, he wanted to turn around and flee.

The fierce battle in the arena had obviously been going on for some time, and at the moment everyone was scarlet, but their eyes were still crazy and greedy.

"Chatter......

At this moment, a strange sinister laugh resounded in the place, making everyone stunned.

I saw that the closed eyes of the grimace sculpture in the hall suddenly opened, and the entire sculpture shattered in an instant, turning into a monstrous black gas, rolling and floating in the sky above the hall and transforming into a huge grimace.

The grimace's face was gloomy, and he glanced at the crowd below, his glittering eyes full of mockery.

"Not good!"

Ye Nan saw this grimace for a moment, and finally knew the source of the power of the summoning power of the Dao, and his scalp was cold at the moment, and his body sped up a little.

However, after only a few feet of escape, he stopped in an instant, because the pattern in the corridor in front of him also had billowing black gas rushing out of it, speeding in his direction.
