The notches on the stone wall seem to be very ordinary, as if they were left by digging holes, but they are so natural that people can't see any clues.

In fact, every notch is a formation.

On this stone wall, there are tens of thousands of notches, in other words, this formation has at least tens of thousands of formations, and each formation is related to the change of the formation.

What Tang Chen could be sure of was that this large formation was composed of at least three small formations, one of which was the phantom formation and the other was the killing formation. 、

As for the third formation, Tang Chen didn't know, but he was sure that apart from these three formations, there was no possibility.

Because of the existence of the phantom array, if Tang Chen wanted to break this prohibition, he had to break this phantom array first.

Tang Chen stood in front of the stone wall, gradually reining in his aura.

Gradually, those who had cultivated to a lower level in the cave all paid attention to Tang Chen's changes. They were here to give advice to the original three formation masters, and by the way, they learned the formation path of those three people.

It's just that Tang Chen's arrival completely messed up their hearts, and they also completely captured their respect, they knew that the young man in front of them was younger than them, and in terms of formation, he had attainments that they admired.

But when the aura on Tang Chen's body converged, they began to wonder, but immediately after, they felt a heavy momentum, and gradually, the terrifying momentum on the young man in front of them also disappeared.

If they weren't able to see it, they would have thought that Tang Chen had never appeared, and even the aura that had been left behind had disappeared.

It's weird!

But a few people still had insight, and they saw the reason, guessing that this was because Tang Chen had entered a wonderful state, and also released a kind of avenue that blended into the surrounding environment.

But they don't know what this avenue is!

Only a formation master, or a super power, knew the purpose of Tang Chen's approach.

Because if you want to clearly understand the formation, you must blend in with the surrounding environment and feel the prohibition of the formation firsthand.

It didn't take long for Tang Chen to include the hundred formations in front of him into the scope of his research, which took him a hundred breaths of time.

And in this hundred breath time, Tang Chen's harvest is very large, this formation pattern is the constituent unit of the entire formation, a hundred formation patterns are a hundred constituent units, there are tens of thousands of daos on the entire stone wall, as long as each one is broken, he can break the phantom array.

The whole composite formation, the role of the phantom array is really not small, it pulls the researcher's thinking in the wrong direction, to achieve the purpose of confusion, as long as the essence of the formation cannot be seen through, it is impossible to break this formation.

Time flew by, and two hours later, Tang Chen withdrew from this state of concentration, and a light of enlightenment flashed in his eyes.

During these times, he analyzed all the carvings on the entire stone wall, and all the factors that belonged to the phantom array were captured by him, and he already knew how to break this phantom array.

Tang Chen's changes, everyone naturally saw it in their eyes, and they all felt that something was going to happen.

At this time, Qian Hai, who was crawling on the stone table to derive the formation, was also awakened by this sudden appearance.

He glanced at Tang Chen and found that Tang Chen was full of confidence, so he couldn't help but ask himself, did he already know how to break the formation?

Tang Chen was focused on the formation, and did not pay attention to the people in the cave mansion, but moved his gaze to the four corners of the stone cave.

This cave is just an irregular circle from the outside, but it is square on the inside, and it is a relatively regular cube.

The eyes of this phantom array are in the four corners of the cube.

Tang Chen walked slowly, glanced at the corner, and found that there was only dust, and nothing else, for these, Tang Chen was not the slightest surprise, and then his right hand was clawed, and he vigorously grabbed the ground in the corner, and inserted his five fingers into the stone together.

Seeing Tang Chen's actions, those martial cultivators began to discuss, and for a while, the silence in the cave was broken, but everyone immediately communicated with each other, after all, they didn't want Tang Chen to be disturbed by them.

Although Qian Hai didn't speak, he was also puzzled by Tang Chen's actions and wanted to ask, but seeing Tang Chen's seriousness, he stopped his thoughts.

Tang Chen was not disturbed by everyone, his hand was still deep in the stone on the ground.

Soon, the stone in Tang Chen's hand shattered, and then Tang Chen grabbed it a few more times, until he dug a round pit with a diameter of three feet, and then he saw a black stone pillar inside.

When the top of this stone pillar appeared, although those martial cultivators did not make a sound, they were transmitting and communicating, and Qi Qi felt incredible.

"Something?"

At this time, Qian Hai couldn't help but be shocked, he didn't expect that there was a secret hidden under the ground.

A hint of surprise flashed in Tang Chen's eyes, but he didn't stop, and gradually, this black ashlar appeared in Tang Chen's hand.

The cross-section was half a foot, and there were several more mysterious formations engraved on it, Tang Chen glanced at it, and soon knew the prototype of this phantom array.

This is just a slightly high basic phantom array, and it takes a certain level of formation to depict the formation pattern, and Tang Chen can't satisfactorily depict such a phantom array for the time being.

However, this phantom formation was only a ground-level formation, and Tang Chen believed that it wouldn't be long before he could depict such a formation.

Now that the first stone platform has been discovered, the other three pieces are simple, and there is no need for Tang Chen to do it, and the rest of the martial arts cultivators have Tang Chen's permission and are busy in the three corners.

A moment later, three identical stone platforms were dug up.

At the moment when the three stone platforms left the ground, the stone walls in front of them suddenly changed, but those nicks suddenly disappeared, and then a flat rock wall appeared, and there was a stone gate in the middle.

However, this stone gate seems to be connected to the stone wall.

"Is this a second layer of prohibition?"

Qian Hai looked at the strange stone gate in front of him and was shocked.

"That's right, if I'm not mistaken, I'm afraid this stone gate is not simple, at least there is a killing array on it!" Tang Chen's face changed slightly, and his expression was solemn.

The prohibition in front of you may not be as difficult to parse as the phantom array, but it is definitely not easy to break it, which requires not only methods, but also strength.

"Is Brother Tang sure to break this prohibition?"

Qian Hai looked at Tang Chen, he wanted to see a confident look on Tang Chen's face, but he was disappointed, because Tang Chen's look told him that trouble was starting now.

"It's not clear for the time being, I'm afraid this prohibition is not so easy to break, and with my own strength, I guess it won't work!"

Tang Chen shook his head, his expression was still serious: "If you want to find the formation eye, I'm afraid it's difficult!"

"If you need my help, Brother Tang can just command!"

Qian Hai's expression was solemn, and then he continued: "However, those people outside may use it!"

"Hmm!"

Tang Chen nodded, he had already felt that several powerful auras flew over.

After a few breaths, more than a dozen figures appeared in the cave.

Six of them are the six people on the stone platform.
