Immortal cultivation starts with copying.

No matter what level of formation, it is ultimately man-made, so there is no perfect existence and there will always be some loopholes.

As mentioned before, finding a loophole in the formation and sneaking in is one thing, and finding the weak point of the formation and breaking it is another.

Formations above level four are called spirit formations, and their operation and arrangement methods are very different from those below level three.

Not to mention Chen Yunhao, even the three knowledgeable ancient painting monks had never seen such a large-scale sealing formation before.

According to the speculation of the three of them, this should be a fourth-level peak formation, and many of the materials used to set up the formation are probably from the upper realm.

So level three to level four is a watershed, but the basics of the formation will never be wrong.

After more than half a year of research, the four of them finally found an inconspicuous loophole somewhere in the entire mountain protection formation.

Although he found the loophole, Chen Yunhao did not act rashly.

They could get in, but they still had to consider how to get out, so the four of them studied it for another three or four months.

During this period, under the guidance of the three people, Chen Yunhao also refined a formation plate.

The main function of this array is to temporarily stabilize the passage in and out after the hole is opened, so that he won't be unable to get in or out.

This mountain protection formation covers a vast area, and the four people worked hard for several months to find this loophole.

At an inconspicuous formation at the foot of the mountain, the four people calculated the formation and conducted more than a dozen experiments, and determined that there was an area of ​​four or five feet in size, which was the weak point where the formation intersected.

Chen Yunhao was seen standing in front of the formation, with an ancient painting floating behind him. The three monks in the ancient painting were using a secret method to communicate with Chen Yunhao.

Chen Yunhao nodded as he listened, holding the newly refined formation plate in his left hand and the Sky-Breaking Sword in his right hand.

Finally, Chen Yunhao let out a low shout and gently thrust the Sky-Breaking Sword forward. The sword shone brightly, and the person it stabbed couldn't open his eyes.

This was Chen Yunhao's full-strength sword attack. The two Nascent Souls in his Dantian sat cross-legged facing each other, and their true essence gushed out like it was free!

This sword directly pierced into the weak point of the formation that Chen Yunhao and others had explored.

The formation was like ripples on water, and from the point where the Sky-Breaking Sword had penetrated, it slowly spread out to the surroundings, and finally turned into a passage more than three or four feet wide.

This passage is barely big enough for one person to fit through, but it is enough.

Chen Yunhao put away the Sky-Breaking Sword and placed the formation plate on the formation with his left hand.

More than a dozen rays of light emerged from the array plate and spread into the opened passage like tentacles.

Seeing that the passage was stable, Chen Yunhao did not dare to waste any time. He turned into a gust of breeze and dived into the passage.

After entering the forbidden formation, what hits you is pure and rich spiritual energy, which is no less than that of Thunder Mountain.

Just based on the concentration of spiritual energy, it is enough to be called a paradise.

Chen Yunhao didn't stop at all and ran straight to the mountain gate.

The place he entered was more than a thousand miles away from the mountain gate. Moreover, the level of the formation plate he refined was not high, and there was a time limit. He had to come out within three hours.

Time was running out, so Chen Hao used the Flowing Light Technique and arrived at the Taiyi Sect's mountain gate in just three or five breaths.

The entire mountain gate is well preserved and has not been damaged. The building complex stretches for more than ten miles and is magnificent. One can imagine how prosperous Taiyi Sect was at that time, and it looked like a major sect.

The entire Taiyi Sect, including this mountain range, is well preserved. The disciples in the sect were dismissed early, so the buildings are also well preserved.

Chen Yunhao had been in a large sect and knew which places were important in the sect.

But this time he came in not to find any valuable things or inheritance, but to find the control center of the entire formation.

Although he found the weak point of the formation, it did not mean that he could enter and exit it many times in the future.

The fourth-level spiritual formation has the function of automatic repair. The passage he opened may be moved to another location after this trip.

Therefore, it is impossible to spend seven or eight months every time entering to calculate the weak points of the formation.

For several months, Chen Yunhao studied the formation from top to bottom, while also observing the building complex from a distance, trying his best to identify where the formation's control center was most likely to be located.

A large sealing formation like this cannot be opened from the outside and can only be controlled from the inside.

Chen Yunhao had already taken a fancy to two or three places, so he went straight there after entering.

The first place is the master's meeting hall, which is located in the center of the entire mountain gate and is also the most conspicuous.

This is a ten-meter-high hall, which is relatively empty except for some tables and chairs.

After entering the main hall, Chen Yunhao went straight to the side hall at the back, which was usually where the head of the sect rested.

At this time, Chen Yunhao's spiritual sense had been highly concentrated, covering an area of ​​only ten to twenty feet. He could sense any dust floating in the air.

Any slight fluctuation of spiritual power can be detected, even in the secret room underground.

After Chen Yunhao came in, he searched carefully twice and then turned and left.

He was about to rush to the next place, and in his mind he was thinking from another perspective: if he were in their shoes, where would he settle such an important place?

Moreover, once this sealing formation is activated, the person who activates it will also be trapped inside the formation. If he wants to get out, he has to close the formation again.

So Chen Yunhao had thought of this a long time ago. Thousands of years have passed, and the predecessor who activated the formation must have died long ago. If he could find his body, he could find the control center of the formation.

The second place Chen Yunhao went to was called Zushi Hall, which is the same as the Zushi Hall built in Tianzhen Temple today.

The founder of Taiyi Sect is enshrined here. It is also a very easy place to find. There are plaques with words on the porch.

The ancestral hall here is like a large palace, more than ten feet high. Inside stands a statue with its hands behind its back. The statue looks about 80% like the ancestral hall enshrined in Tianzhen Temple.

But the statue of the ancestor here is taller and more lifelike. I don’t know what material it is carved from, but it looks so lifelike.

Chen Yunhao walked to the front of the ancestral hall and gently pushed open the door. An invisible pressure hit him in the face.

This pressure came from the statue of the ancestor, making Chen Yunhao feel as if he was facing Lin Changfeng, the pressure was enormous!

After he came in, he took a look at the statue of the ancestor and found that the two huge eyes on the statue seemed to be looking at him, with an unfathomable light flashing in the eyes.

But Chen Yunhao was certain that the statue of the ancestor was a dead object, and there was no way it could be taller than ten feet.

Taiyi Sect is the predecessor of Tianzhen Temple. Chen Yunhao has been worshipping this ancestor since he was a child, so after he entered the sect and took a look, he knelt on the ground.

"Chen Yunhao, a later-generation disciple of Taiyi Sect, pays homage to the Grandmaster..."

Chen Yunhao kowtowed three times in a row. No matter whether he could find the control center of the formation or not, he had to pay homage to the ancestor when he met him!
