Chu Yuan and the others walked all the way towards the upper reaches of the river, and they also encountered a lot of heavenly and earthly treasures along the way, all of which were beneficial to the soul spiritual power.

Chu Yuan is guarded, not moving for the time being, in this world, soul things are treasures.

An army of 50,000 men marched day and night to the end of the river for three years.

In the past three years, Chu Yuan and the others have encountered all kinds of creatures, but fortunately, their cultivation is not very high, that is, everyone's morale is getting lower and lower, and they can't see any hope for three years.

"The water has been calming down a lot in the last few days, but the cold is getting heavier and heavier, and I guess it's almost at the source. The elder brother said one by one.

Sure enough, soon everyone saw a high platform in the distance, and the cold water flowed out from under the high platform.

It didn't take long for the crowd to come to the clearing.

"Nothing?" Many people saw this scene and looked a little lost.

"This place seems to be some kind of ruin. Zhu Yuanqi said.

"There are a lot of strange symbols around, could it be that someone once lived here?" Situ Haoyu said.

"It doesn't have to be human. Chu Yuan said: "The surrounding area is not like a building ruins, but like a place of sacrifice, or a ritual. ”

"Why don't you smash it open and take a look?" said Jier.

"If it's a ceremonial place, there should be a formation or something nearby, let's look for it?" said Ji You.

"What Senior Sister said makes sense, maybe we can still figure out the origin of this great world!" Chu Yuan said.

The Xuanhuang Realm has disappeared more than one hundred and forty Yuanhui, and there are already about one hundred Yuanhui in this big world, one Yuanhui is close to 130,000 years, and every Yuanhui in the Emperor Realm has to cross the catastrophe, and if you can't cross it, you will die, to a certain extent, it can be regarded as transcending the life rules of heaven and earth, and the Imperial Realm also has the longevity of ten Yuanhui, and the Great Sage Realm has the longevity of one Yuanhui.

"You guys, I think we can start with the materials on the ground. Jier said.

The crowd didn't bother to pay attention to him.

After a while, a few or two actually made a discovery.

"Look, this floor tile has a foundation material every three layers, and I have removed nine layers. Jier shouted.

Everyone gathered around, Chu Yuan took a look, and sure enough, it was the foundation of the formation.

"There are formation bases on every third floor, haven't you heard of this kind of formation?" Zhu Yuanqi said.

Chu Yuan hadn't heard of it either, so he looked at the river in the distance and said, "You guys take a look here, I'll go down and see the source of the cold qi and see what it is." ”

"Well, be careful, the cold almost killed me. Zhu Yuanqi said.

Chu Yuan nodded, and came to the outside of that dark cave, the cold air here was already shivering, Chu Yuan had to operate the Participation Deed, and the Danhuo also wrapped itself.

Thump!

Chu Yuan jumped directly and slowly touched the ditch to enter.

It was dark and you couldn't see anything, and it was in the water, and the scope of your consciousness was limited.

It didn't take long for a faint light to come from ahead, and the chill was getting stronger and stronger.

There was a stone platform at the bottom of the water, and there was a bead on it, which Chu Yuan didn't recognize, but he could be sure that the chill was emanating from the bead.

Originally, Chu Yuan planned to take the beads, but then he gave up when he found that the stone platform was also the foundation of the formation, which means that this bead was the source of energy for this formation, that is, the eye of the formation.

Other than that, nothing was found, and even some demon beasts cultivating in the cold pool did not dare to approach this level of coldness.

After coming out, Chu Yuan told everyone about the situation.

"I don't know if this formation is good or bad, I don't know what kind of formation it is, and I don't even know how to activate it. Chu Yuan said.

"Whatever the hell, look around, the endless deep forest wilderness, maybe this thing can help us find our way out?" said Jier.

Chu Yuan looked at everyone and felt that it made sense, anyway, a dead horse should be regarded as a live horse doctor.

"Alright, let's look again to see if we find anything that can activate the formation. Chu Yuan said.

"Then I'll put the tiles back. Jier hurriedly said.

Half a day later, everyone still didn't find anything.

"It's weird!"

A group of people was completely confused.

"You say, could this be a teleportation array?" said Ji Shu suddenly.

Chu Yuan thought for a moment and said, "There is this possibility, but if it is a teleportation array, where can it be teleported here? What teleportation array can exist without maintenance for a hundred yuanhui?"

"Try it, the teleportation formation is simply to inject spiritual power, don't you have a spirit stone on you. Jisan said.

"It's okay, then try!" Chu Yuan said: "You retreat first, if it's a teleportation array, you can bring the army over later." ”

"Good. ”

After everyone withdrew, Chu Yuan took out a lot of spirit stones and put them in the four corners of the table, and then the spiritual power began to connect along the formation base.

Thundered!

Suddenly, the entire stone platform began to shake.

"Is it really a teleportation array?" The people below were a little surprised, this is hope.

Soon, a six-pointed star array rose from under Chu Yuan's body, slowly rising into the sky, and then, it seemed that the nine heavens also vibrate.

"What's the matter, doesn't it feel like a teleportation array?" said Jier.

And the people were puzzled.

Not only here, but the whole world is shaking, alarming everyone on the battlefield.

Soon, the shaking stopped, and many people didn't know why the world was shaking.

On Chu Yuan's side, the six-pointed star array in the sky suddenly shone brightly, and a huge pillar of black-purple light shrouded from above.

Thundered!

There was another sway, and a huge stone gate appeared in front of Chu Yuan, and then the light in the sky began to dissipate, and everything returned to calm, only one more stone gate.

The pillars on both sides of the stone gate are carved with very strange species, and the whole stone gate exudes an evil nature.

At this time, quite a few people came up.

"Such an evil nature, could it be that it leads to a world of evil cultivators?" said Ji'er.

"Chu Yuan, what's going on?" asked Situ Haoyu.

Chu Yuan couldn't make up his mind, who knew what was behind this stone gate?

Just when everyone was uncertain, the stone door slowly opened.

"Damn, this thing can open on its own!" shouted a few times, and everyone hurriedly stepped back.

A cold aura rushed out of the stone door, accompanied by a faint black mist.

Soon, a tall figure walked out of the stone gate, which made everyone's hearts rise to their throats.

Soon, the figure was completely exposed in front of everyone, more than two meters tall, a humanoid creature, holding two black sickles, with silver hair, although wearing a black cloak, it gave people the same feeling as the species they had encountered before, very empty, and exuded a faint demonic and evil aura all over its body, but it was not the same as those evil cultivators.
