Although Hechi's experiment was a little stupid, after Hechi's experiment, it could be regarded as directly overturning Lin Feng's conjecture.

"Since it's not, what does it mean?" Lin Feng looked at the eight stone walls speechlessly.

Then, in front of the eight walls, a group of strange people appeared, all of whom were standing upside down, looking at the surrounding walls, and then sighing and shaking their heads one by one.

"Not even a hint. Lin Feng looked at the stone wall in front of him with a headache, and lay on the ground weakly.

After studying it for so long, I still don't have a clue, no matter what the attack is, it doesn't seem to have any effect on the stone wall, and it will be sucked directly into the void, and the stone wall still looks like nothing has happened.

It seems that everyone is really trapped here.

Lin Feng, who was lying on the ground, looked at the dome of the closed stone room blankly, and the appearance of the dome was very similar to the appearance of the ground under his feet.

Lin Feng's eyes suddenly changed a little, the appearance of the sky dome and the ground under his feet was really similar, but there were still some subtle differences.

There seem to be some subtle lines carved into the ceiling, but the ground under his feet does not have this part of the line.

Those subtle lines are extremely tiny, if you don't look closely, you really can't see it, and that front is like a kind of formation.

Lin Feng jumped up from the ground and directly took out a large handful of spirit stones, since there was a lack of formation on this ground, then he would make up for this formation, wouldn't it be over.

After quickly grinding the spirit stone and getting a large amount of spirit stone powder, Lin Feng saw that he began to carve it on the ground according to the formation on the ceiling.

Soon, everyone also saw Lin Feng's movements, and they all stopped what they were doing and concentrated on watching Lin Feng draw a front.

However, after Lin Feng finally finished carving the front after spending a long time, he found that there was no change in the surroundings.

"I thought you had something to do. Lan Lan stood outside the formation and shook her head.

Lin Feng stood in the formation, but his face became a little weird, and he muttered: "I see, I said that this formation looks a little familiar." ”

When everyone in Sword City heard Lin Feng muttering to himself, they were all a little confused.

"I know what to do. Lin Feng smiled and said.

Ji Hui walked into the formation in confusion, but found that his legs sank suddenly, and the body in this formation suddenly doubled, but this gravity doubled, it still had no big impact on the monk, at most, when he began to take it by surprise, his feet softened.

"Is this the Negative Mountain Formation?" Ji Hui glanced at the formation diagram and frowned.

Lin Feng nodded: "It's a very primitive negative mountain formation, now that the formation has been perfected, it is much more advanced than the formation of this ancient era, and the efficiency of the use of spiritual power is much higher than that of this negative mountain formation." ”

"But what's the use? Ji Hui was puzzled.

Lin Feng smiled: "When we go up, you will know if it is useful or not." ”

"Up?"

Lin Feng nodded, from the beginning, perhaps, everyone thought about the problem as complicated, or rather, Lin Feng's clever way of blowing up the door made himself a trap.

Lin Feng disrupted the formation under his feet, and then directly crushed a high-grade spirit stone, guiding the huge spiritual power to rush into the ceiling above his head.

The negative mountain formation, which had obtained spiritual power, began to operate in an instant.

Then everyone collectively felt a powerful suction force coming from the top of their heads, and everyone hit the ceiling like dumplings.

But the people present were not ordinary people, and after the initial panic, they immediately reacted, and they all turned over, adjusted their postures, and landed safely on the ceiling.

Lin Feng stood on the ceiling, looked at the top of his head, and smiled bitterly: "This can be regarded as opportunistic retribution." ”

The original ceiling became the floor, and the original floor became the ceiling, and there was no other reference in this enclosed space, so there was no discomfort in changing positions back and forth.

At this time, Lin Feng looked at the eight walls again and found that all the patterns were clear at a glance.

Looking at the eight walls, everyone in Sword City also understood.

"This blood source crystal is not only a condition for the opening of the secret realm, but also the power source of the secret realm, without the power source, it seems that many formations cannot be activated, and we will encounter the situation just now. Lin Feng smiled bitterly.

Yu Hong touched the stone wall again this time, and sure enough, it was a teleportation formation, and his hand could be directly submerged into the stone wall.

"I really didn't expect to cheat myself. Lin Feng said in his heart.

At this time, the formation under his feet suddenly began to fade brightly, and Lin Feng also felt that his body was getting lighter and lighter, and it seemed that he was about to have another gravity reversal.

"Let's go through a teleportation array together, don't scatter, the spiritual power of this high-grade spirit stone can't even withstand consumption. Lin Feng frowned and said.

The closest thing to everyone in Sword City was the stone wall with a rabbit pattern, and everyone no longer hesitated, and they all rushed into the stone wall's teleportation formation.

At this moment, there were many people on the top of the mountain, and when they saw the unrecognizable mountaintop, many people couldn't hide their surprise.

Especially those monks who had already gone to the top of the mountain, it was like the Green Immortal Sect, and everyone in the Green Immortal Sect couldn't believe their eyes.

Whether it was the post-modern warning sign or the teleportation formation, they were all gone, and only a strange yellow building was left in front of him, with a dark and empty door, open to everyone.

"What's going on?" asked a monk in a blue and white robe, frowning.

The characteristic Dao robe with obvious separation of left and right white is undoubtedly a person from the Wind Thunder Sword Sect, and the young man who leads it is undoubtedly a genius disciple of the Wind Thunder Sword Sect.

But at this moment, how can there be a simple and easy-to-get along character who rushed to the top of the mountain, the Wind Thunder Sword Sect, does not have so much influence, so naturally no one pays attention to this young man.

The Void Scholar also looked at the situation in front of him blankly, he and the others, after a lot of hard work, finally got together enough Blood Source Crystal, but he didn't expect to see such a scene as soon as he went to the top of the mountain, this kind of blow was really too big.

Mo Yan suddenly appeared behind the Void Scholar: "This was the case before I came. ”

The virtual scholar looked at Mo Yan, and then looked at the scene in front of him, and he didn't know what to say.

The people from the Western Regions Alliance came a little earlier than the Qingying Immortal Sect, but at the moment they were watching from the sidelines, obviously these people must know something they didn't know.

"Senior sister, it's all your fault, we're all late. A reproachful voice came from behind.

I saw Liao Shu blocking her ears and walking up the mountain with an impatient face, and the people from the Qiankun Divine Cave also came.

This time the top of the mountain can be regarded as lively, the Western Regions Alliance, the Wind Thunder Sword Sect, the Qingying Immortal Sect and the Qiankun Divine Cave have gathered, and there are more forces behind that have not yet arrived.

"What are you waiting for, staring at each other, isn't it funny, if you don't enter, then I'm welcome, don't say I didn't let you go first." Liao Shulian moved slightly, her demeanor was dignified, but she said incomprehensible words.

"Looking at it like this, there must have been someone who took the lead, but this secret realm is similar to that of women, and only those who have been developed have a taste. Liao Shu licked her lips and stepped into the dark door.

I'm looking forward to it, when she enters the door, she looks like a green onion, and when the time comes, the skirt or something, eh, hey, hey.
