If it is a formation, then there will definitely be a formation.

Xiang Yang compared all his memories with those jade slips one by one, and the tortuous routes clearly appeared.

In this regard, his memory was exactly the same as the record of the jade slip, and sure enough, it was fourteen lines, and the only thing he didn't figure out was where the extra cave was?

"Don't worry about it for now, in my gut feeling, the route of these caves seems a little weird!"

Xiang Yang directly calculated in the sea of knowledge, and according to his own memories and the help of those jade slips, the zigzag lines gradually formed, turning into mysterious lines.

"Sure enough, these caves are the foundation of the formation!"

For a moment, his heart was clear, and the original blankness disappeared.

People, even immortal cultivators, are most afraid of facing the complete unknown.

If an ordinary person is in a completely enclosed and dark space, for a long time, it will produce all kinds of hallucinations that affect your mind, but at this time, as long as a little light appears in this space, even if it is only a small point, it can bring you great hope.

"Next, it's time to analyze the effect of this formation!"

"Well, this one seems to be somewhat similar to some kind of ancient fantasy pattern, but the shape is different, and there are many changes in it that I have never seen before..."

"This path is to enhance the spiritual sense, the sense of divine sense, no wonder I am in this cave, the spiritual sense seems to be unhindered, and even the scope of detection is wider than before, you know, I am underwater, even if it is pure water, it still has an impact on the spiritual sense..."

"Where's this one..."

With Tianyan's cooperation, Xiang Yang analyzed it over and over again, from sunrise to sunset, a whole day and a night, before he stood up, and in his eyes, the color of confusion had completely dissipated, replaced by a confident light!

"Hmm, that's right, this formation can only affect people's spiritual consciousness and divine consciousness, in Tianyan's terminology, it affects spiritual power!"

"These caves, the deepest part reaches thousands of zhang, the underwater pressure is definitely not something that ordinary people can bear, only immortal cultivators can enter, and when they go to that kind of place, they must use spiritual power to guide the way and observe the surrounding environment. Although I don't know its specific effect yet, this formation must affect the spiritual power, and through some means, forcibly tamper with memories and judgments, causing illusions!"

"But what if I don't use my mental power, but my eyes, then it shouldn't be affected!"

Xiang Yang looked at the floating jade divine mountain, and a smile appeared on his face.

......

Three days later, when he entered the cave for the ninth time, he found some special changes in the deepest part.

In the spiritual sense, this is a completely smooth road, go along the road, and after two hours, there is the exit at the other end.

However, under the reflection of the luminous pearls, at the bottom of the side of the road, there was a small hole, very small, only allowing one person to drill straight through, and the hole was still floating with flocculent aquatic plants of the same color as moss, if it was not for Xiang Yang to observe carefully enough, I was afraid that I would miss it.

"This should be the place! I don't know what's strange in this cave..."

Xiang Yang directly took out the eight substitute mortal bodies that were only left once, and then put on a few defensive magic weapons, and then cautiously walked towards the entrance of the cave, shrunk his body, and went down directly.

Inside, there was a smooth, straight down passage, and I don't know how long it had been sinking, and the pressure around it was getting more and more intense.

Xiang Yang silently counted the numbers, and when he was about 10,000 zhang or so, he stepped on solid ground under his feet.

At this time, he had already put away those defensive magic weapons, and the pressure on his body was already huge, even his flesh had a feeling of tightness, according to his estimates, ordinary barbarian emperors here, if they were not crazy, it was estimated that they would be directly crushed into pulp.

Afraid that this place would still be affected by the formation, he took out the Night Pearl and wanted to observe it, but he didn't expect that before he could start it, the Night Pearl was silently pressed into powder by the strong water pressure...

Avoiding water droplets is just as useless...

"It looks too deep and the water pressure is too strong... But it's so far away from the formation above, the spiritual sense should be able to use..."

He reluctantly gave up the idea of continuing to observe with the naked eye, and reached out for his spiritual sense.

The surrounding area was a closed space about ten zhang wide, surrounded by solid stone walls, and he searched inch by inch, without any abnormality.

"No... How can this go up..."Xiang Yang smiled bitterly and leaned upwards with his spiritual sense, above was the passage when he came, one person came wide, and his hands and feet could not be used after entering, and with such a huge water pressure, even he had no confidence to climb up.

"Do you want me to carve a passage alive?"

For a while, he had a headache, with his wishful stick on his body, with his brute strength and the resources in the Qiankun Ding clone, he was naturally not afraid of being trapped and dying here, but in this way, he would open the mountain and split rocks all the way, not to mention the big movement, and it might also destroy the formation and some arrangements here, and it would be unknown what would happen to the accident or what clues would be missed.

Just as he was hesitating, suddenly there was a 'click' sound from the stone wall in front of him, his eyes lit up, and before he could fully recover his senses, the stone wall slid away directly, and the water rushed forward with him.

With a bang, he threw himself forward, quickly turned around and moved, and only then did he stabilize his footsteps, and there was an open space in front of him, and beside him was a waist-length pool, and the stone wall behind him was silently re-covered.

"Here it is..."

Xiang Yang looked around, this was a huge space, it looked like it was ten thousand zhang square, and the surrounding stone walls exuded a faint milky white light, reflecting the entire space transparently and clearly.

However, what surprised him the most was that in the very center of this space, there was a... Altar of Sacrifice!

Compared with the sacrificial altars outside, this black altar is undoubtedly much smaller, only a few dozen zhang high, but both the shape and the aura it exudes are exactly the same as the altars in the barbarian camp, as if they are a miniature version of them.

"At the foot of the Floating Jade God Mountain, there will be a sacrificial altar?"

Xiang Yang suddenly smelled a strong aura of conspiracy, the Floating Jade Mountain Range was tens of thousands of miles away from the Qitian Mountain Range, and the back hands of this barbarian were all arranged here?

Just as he hesitated, a vicissitudes of voice sounded in the direction of the sacrificial altar.

"Descendant of the beast god, you're finally here!"
