In front of the crack, Xu Yan frowned, and the bones piled up like a hill in the square gave people a horrifying feeling.
What surprised him most at the moment were the monks' bones, because these bones all had a common characteristic.
That is, the heads of these monks' corpses are carved with one long, two short, and three strange lines.
These three lines are crooked and twisted, as if they were painted randomly by a child, but if you look closely, you can find their special features.
The three lines glowed with a faint black light, and attached to the monk's corpse, the skull twisted slightly, like a living creature. Although it was still far away, it gave Xu Yan an extremely evil feeling.
"There are no fewer than a thousand monks' bones in front of us. I'm afraid most of the monks' bones who entered Ancient Demon Abyss to seek opportunities are here."
Xu Yan looked away from Bone Mountain and muttered to himself.
However, this also confirmed his suspicion that Demon Ape indeed hides some kind of secret.
There are four huge bloody stone pillars that have collapsed around the square, with various twisted and strange lines carved on them. It seems that many of the lines have been blurred due to the age.
There is a huge statue of a figure in the center of the square. It looks like a middle-aged male cultivator with a majestic appearance and a stern face.
The middle-aged male cultivator also has three strange lines between his eyebrows. In addition, he holds a stone ball in his left hand and holds a giant ax high in his right hand. His legs are slightly bent, and he is about to fly away from the sky.
This statue is extremely expressive, giving people an immersive feeling, and they can vaguely feel the tyranny of the middle-aged monk.
This huge statue was dilapidated from the waist down, which weakened the artistic conception a lot.
Xu Yan glanced around the huge statue and continued to look inside. That was where Demon Ape finally stopped.
Soon, a huge dilapidated stone palace appeared in Xu Yan's field of vision.
"It seems that this place is inextricably connected with Ancient Demon Race." Xu Yan had a vague guess in his mind.
This huge stone hall has a main hall and four auxiliary halls. The main hall is in the middle and is made of huge stones. It is more than ten feet high and has strange runes carved on it. On the top of the main hall is a huge black stone round tripod, which looks like Pill Furnace.
The four slave halls are much lower than the main hall, and have all collapsed. There are ruins and broken walls everywhere, and they look dilapidated.
In Xu Yan's induction, Demon Ape is now in the huge stone main hall.
At this moment, he was several miles away from the main hall, and it was difficult to find out what was going on inside the hall.
He stood there for a few breaths, and after Divine Sense scanned the surroundings and found nothing unusual, he jumped down.
Feeling Bone Mountain at close range, the evil feeling became more and more intense. Xu Yan enveloped Divine Sense on the corpse of a monk closest to him, trying to find out the strange lines on the monk's head.
Before, he was Bone Mountain more than a hundred feet away and Divine Sense was out of reach.
Divine Sense shrouded it, and the one long and two short lines had obviously changed. The black light around the body swelled, and the evil aura rose into the sky.
The sudden change made Xu Yan's complexion change greatly, and he quickly took back Divine Sense, for fear of shocking Demon Ape in the stone palace.
"It should be some kind of special rune, but I don't know what it does!" The incident just now made him make a judgment in his mind.
But now is not the time to explore. The secrets on Demon Ape are obviously more useful. After controlling his aura, Xu Yan quietly walked towards the huge stone palace.
This square seems to have existed for too long, and the ground originally paved with huge stones has weathered a lot and is overgrown with weeds.
The square and the huge stone palace are several miles apart. Xu Yan walked for a full stick of incense before arriving near the huge stone palace.
About tens of feet away from the stone palace, Xu Yan stopped.
This position happens to be the limit of his Divine Sense release range. Here he can use Divine Sense to completely cover the huge stone temple.
After looking around, Xu Yan found a huge boulder as tall as a person, which seemed to have rolled down from the side hall.
Without any hesitation, he immediately came to where the boulder was and sat down cross-legged.
Divine Sense slowly came out and rushed towards the huge stone palace.
"Chichi! Chichi!"
In the huge stone hall, the injured Demon Ape pointed at the wound on his chest, roared and began to gesture.
In front of the injured Demon Ape, there were seven or eight figures of the same pitch black shape. They were also Demon Ape, but their bodies were much bigger than the injured Demon Ape.
Sitting in the middle was a Old Devil ape with white beard and eyebrows. After hearing the roar of the injured Demon Ape, a look of thinking appeared on its dark face.
Upon seeing this, the other Demon Apes also cast their gazes on the Old Devil ape, as if waiting for it to make some kind of decision.
It's not dark inside the main hall, Demon Ape is just in a corner of the main hall.
On the ground in the center of this huge stone hall, there is a huge black stone round tripod. Under the round tripod, there is a broken formation, which is emitting white light at this moment.
There were dense sounds coming from the black stone round cauldron, like the sound of thin rain.
There are also four huge stone pillars surrounding this huge stone hall, with images of tall figures wearing animal skins carved on them.
Everything in the hall shows that the real owners of this stone hall are not these Demon Ape, they just occupied this place later.
"Roar!"
An angry roar sounded, and the white-haired Old Devil ape stood up and looked up to the sky with a roar.
At this moment, the Old Devil ape's whole body was full of momentum, already surpassing the ordinary Qi Refining Perfection monks.
From the description of the injured Demon Ape, it could be confirmed that the human monk was not the Foundation Establishment Realm monk, which gave Old Devil ape a lot of peace of mind.
Although according to its speculation, the monk will die soon and all he has to do is wait, but when he thinks that Spirit Treasure in the black stone round cauldron is still a little short of being perfected, it becomes a little impatient.
After taking it according to its speculation, it is very likely to advance to Second Tier, which will give it a strong desire.
Like those monks who entered Ancient Demon Abyss, Old Devil's death is approaching, and if he cannot advance, he will completely die.
Outside the huge stone hall, Xu Yan looked solemn. He Divine Sense had already reached in just now, so he naturally knew everything.
"There is actually a nest of Demon Ape in this stone palace. It seems to be a dove occupying a magpie's nest!"
"The broken formation in the center of the stone palace feels inexplicably familiar. It seems to be recorded in Kong Xuan's memory."
Xu Yan stared at the huge stone hall with various thoughts in his mind.
In his opinion, the secret of Demon Ape is hidden in that huge stone hall.
"Demon Ape is no more than Mortal Demon Bloodline. It seems that Old Devil's ape aura is about to advance to Second Tier. The secrets in this huge stone hall look quite extraordinary."
Xu Yan had a look of greed on his face and a cold light in his eyes.
Among this group of Demon Ape, only the Old Devil ape is quite troublesome, and the other Demon Ape are no more than monks equivalent to Ninth Layer of Qi Refining.
