With previous experience, Chen Feng was very relaxed to catch the giant ghost. The only thing that was a little troublesome was the giant ghost with two heads and four arms. However, after being hit by a few fierce blows and half of his body was blown out by the giant flame palm, it was finally stuffed into the gourd by Chen Feng.

As for the remaining evil spirits, Chen Feng was too lazy to kill them by himself, and urged the guardrail gourd to fly forward, and he could take them away on the spot with a light cover.

After all the evil ghosts that escaped were cleared, Chen Feng activated the guardrail gourd to fly into the stone pit, aimed at the gap where the evil ghost escaped, and began to crazily suck the evil spirit leaking out of the gap and the evil ghosts that kept flying out.

Lan Changtai walked over at this time and waved his hand. The gravel, soil, and moss that had accumulated for many years had crushed the gravel, soil, and the moss that had accumulated for many years and blew it clean.

Only then did Chen Feng see that under the stone pit, there were circles of runes, intertwined and combined with each other, forming a complex and huge formation. The gap facing the guardrail gourd was exactly the center of the formation.

"In the beginning, my senior from Qingyang Sect protected this secret realm from invasion and destruction by outsiders, so he blessed such a formation outside to seal it. Unless there are more than two powerful people in the Emperor Realm at the same time, they cannot be opened." Lan Changtai looked at Chen Feng and said, "At that time, Junior Sister Su Xin was sealed in the secret realm and became a gatekeeper. I still feel heartbroken when I think about it. This time I came here to rescue her. You just need to help me..."

"Don't say extra nonsense." Chen Feng waved his hand and interrupted Lan Changtai's words. He walked around the formation under his feet, and then said, "How to open it?"

While speaking, Chen Feng passed the thoughts to Jin Jian and said, "There will be some danger next time. You three should stay away quickly and leave as soon as possible. Go and ask for help as soon as possible. I think Lan Changtai is an old guy with ulterior motives. Maybe there is something amazing secret hidden in this secret realm. I may not be able to deal with it by myself, so it is better to go and find some help."

Jin Jian nodded, but did not rush to leave, so as not to arouse Lan Changtai's suspicion.

"It's very simple. Just use your true energy to activate the formation on your side, and I will do it here." Lan Changtai pointed to the formation under his feet and said.

Chen Feng immediately understood what he meant, because he could see that although the formation on the ground seemed to be one, it was divided into two parts. If it was really as simple as Lan Changtai said, you just need to continuously input the true energy into it.

It is definitely not easy to activate the formation that requires the true energy of two powerful people in the Emperor Realm.

What made Chen Feng secretly wary of was whether Lan Changtai would take the opportunity to cheat him.

Chen Feng had no trust in Lan Changtai from beginning to end, and I think Lan Changtai would do the same for him.

The two of them were fighting for life and death before, and they wanted to slap each other so much that they didn't even have any scum left. Now they have started to cooperate again, and it is conceivable that there is basically no trust between them.

Especially Chen Feng took the opportunity to blackmail Lan Changtai many benefits before. If Lan Changtai didn't hate Chen Feng at all, it would be a lie.

Both Chen Feng and Lan Changtai knew this situation very well, so even if they wanted to cooperate, they were actually very energetic and were on guard against each other, and they were afraid that they would be tricked by each other.

This is what Chen Feng is worried about now. He felt that Lan Changtai would rather suffer losses and lose face and would have to help him activate the formation himself. This formation may not be the key to opening the secret realm. Maybe there is some unknown mystery hidden under this formation.

If he really listened to Lan Changtai's words and poured his true energy into it to activate the formation, he might be killed by Lan Changtai.

After thinking about it, Chen Feng decided not to follow Lan Changtai's routine, so as not to be taken into the ditch by him without even realizing it.

"With this formation, can we open the secret realm here?" Chen Feng looked at Lan Changtai and asked.

"That's right." Lan Changtai nodded.

"Since you are just trying to open the secret realm, it doesn't matter whether you use this formation or not. How about I change the method?" Chen Feng said.

"No." Lan Changtai refused on the spot without thinking. Then he seemed to realize that his attitude was a little too impatient, so he explained: "It's not that I don't believe in your method, but this is the method passed down from my Qingyang Sect. It is the most safe and safe. I don't want Junior Sister Su Xin to have any danger. I will only ask you one question, whether to help or not?"

"Help, of course, I have to help." Seeing Lan Changtai like this, Chen Feng felt more and more that there must be something wrong with this formation, but he did not expose it on the spot, but said with a smile: "Come first, I will learn it again and again before taking action."

"Okay." Lan Changtai seemed to have expected Chen Feng to react like this, and immediately stood beside the half-form that he chose, then pinched the magic formula and hit the formation under his feet.

As the magic technique containing his true energy landed, the originally ordinary half-formation suddenly shone with rays of light, extending continuously along the runes, and finally sank into the hole at the center.

"Ao." Just at this moment, a shrill cry came from the cave, full of despair, as if it was the wailing of a wild beast before death.

And the one who can make such a sound at this time must be the evil ghost under the hole.

Chen Feng didn't know what was happening in the cave, and was curious. He released his spiritual consciousness and wanted to peek down through the guardrail gourd blocking the hole, but found that his spiritual consciousness was blocked by an invisible force.

When he insisted on continuing to investigate, he suddenly felt an extremely dangerous feeling, which reminded him of the feeling when he was facing the turbulence of the void for the first time.

Chen Feng did not take any more risks, but took his spiritual sense back, then placed it on the formation under his feet, and repeatedly glanced over and over again, gradually understanding what Lan Changtai wanted to do, and couldn't help but sneer secretly.

"What are you waiting for? Take action quickly. I can't stand it for too long." Lan Changtai couldn't help but urged anxiously when he saw that Chen Feng had not helped.

"Don't worry, I promised you that I would not break my promise." As he said casually, Chen Feng followed the same tricks and hit the formation in front of him.

The magic trick fell to the ground, and the light rippled up. Then layers of runes lit up quickly and extended towards Chen Feng, hooked up with his hands, leading him to continuously send his true energy into it in order to promote the operation of the formation.

By this time, Chen Feng was already riding on the back of a tiger, and it was unlikely that he would stop halfway. Either he would constantly consume his true energy and enter the formation until he filled it before he could get rid of it. Or he would be forcibly drained by the formation, or even the essence in his body until his vitality was exhausted and he died.

Whether it is active or passive, Chen Feng would not feel very uncomfortable, so he looked up at Lan Changtai opposite him.

"Don't panic, this is a very normal situation. As long as you activate this formation and open the secret realm, you can naturally relax." Lan Changtai advised with a smile: "You see, I'm different here. If there is really danger, I will be the one who is unlucky."

"Hmph!" Chen Feng didn't say anything, expressionless, but he snorted coldly in his heart. Lan Changtai's words sounded right, but this made Chen Feng conclude that he wanted to use this formation to kill him. It was very likely that he was planning to use his true energy in a short time to completely lose his ability to resist, and then he could conquer himself at will.

"If Lan Changtai really wants to do this, then he is very wrong. The true energy I have accumulated in my body is much more than he imagined." Chen Feng sneered in his heart, but he felt much more at ease, but he didn't want to just deal with it passively.

Looking down at the formation underground in front of him, Chen Feng's thoughts flew around and soon came up with a way to let Lan Changtai suffer.

The next moment, Chen Feng activated his true energy and actively sent it into the formation, but he was not in a hurry to push the formation to operate, but secretly refining the formation.

Just now, Chen Feng glanced at the formation with his spiritual sense and found that Lan Changtai was not completely lying. Although this formation would crazily absorb the true energy of the person who opened the formation after it started to operate, it could be called a deadly pit, but it was indeed the entrance to the secret realm. It was really not easy to open it, and it might take several lives.

This time, Lan Changtai obviously used Chen Feng as a power bank, and wanted to squeeze his true energy to activate the formation to open the secret realm. Wait until Chen Feng's true energy is consumed before killing him.

But Lan Changtai didn't expect that although he had a good plan, Chen Feng was not the kind of idiot who was blinded and unknowingly unknowingly.

Now that Chen Feng had figured out Lan Changtai’s plan, he thought of slapping him backhand, and the best way was of course to take the entrance to this secret realm for himself.

In this way, not only can you enter and exit the secret realm at will, but it is also equivalent to controlling the secret realm in your hands. At that time, it may be able to determine the life and death of people in the secret realm.

Thinking of this, Chen Feng became more and more excited, but the expression on his face was helpless and a little resentful, as if he was very unhappy but had no choice but to be plotted by Lan Changtai.

Lan Changtai secretly saw Chen Feng's expression and couldn't help feeling very happy. He immediately gradually reduced the input of true energy into the formation.

The two parts of this formation seem to be separate, but in fact they are connected to each other. Therefore, even if Lan Changtai does not input the true energy, he can still rely on Chen Feng's true energy to activate it. However, in that case, it will inevitably have to wait a long time. At the same time, the true energy that Chen Feng needs to consume will increase exponentially.

However, for Lan Changtai, this is not a problem, on the contrary, it is what he wants to see.

As Chen Feng expected, Lan Changtai wanted to use the formation to suck Chen Feng's true energy dry, and then kill him when his strength suddenly decreased.

Now looking at Chen Feng's frustrated and annoyed expression on his face, Lan Changtai was so happy that he wanted to appreciate it for a while.
