Li Xian and the ghosts were like a flock of geese migrating south, flying over the sky of Qianshan City in the dark.

Naturally, all human beings cannot be seen, only half-ghosts and spirits can see.

"Did something big happen?"

"It's not going to be a group fight, is it?"

"Look, the leader is actually two heaven-level half-ghosts!"

……

The half-ghosts who saw this scene couldn't help but talk about it.

Li Xian is not a high-profile person, but the feeling that Lin Wei conveyed is getting worse and worse, and he has no time to think about the details.

Since the brothers are determined to help, they should go together.

In the blink of an eye, the building of the Qianshan Animal Research Center appeared in front of Li Xian and others.

It was a twenty-story building, but humans could only see nineteen floors, and the top floor had been ghostly and ghostly, and only half-ghosts and spirits could see it.

"Brother Li Xian, this is it!" Xiao Qian pointed to the building and said.

Li Xian breathed a sigh of relief. He had always been worried that the location of the Dragon Master was the same as that of the Eagle Master, hiding in the mountain, so it would be a bit troublesome to break in.

An even stronger coldness and fear were transmitted into Li Xian's body, and Li Xian's heart fluttered, and he flew towards the twentieth floor of the building first.

"Brothers, rush!" With a wave of his hand, the iron wolf also led everyone to follow him.

When he was still dozens of meters away from the building, Li Xian hit his head against an invisible wall.

"Be careful, there's a wall technique!" Li Xian shouted.

This wall technique is exactly the same as the one that Lao Wang arranged around the Yang Qi Factory.

As soon as the words fell, all the ghosts who were fast also hit the "wall" one after another, and the slow ones fell directly to the ground. The reaction was fast, and after falling seven or eight meters, he flew up again.

Most of the ghosts of the Alliance had never touched the wall technique, and they were all shocked.

"Is there such a powerful ghostly art? You can even block an invisible wall out of thin air! ”

"It's the first time I've ever seen a wall technique! This wall is just like the real thing, except that it can't be seen! ”

While discussing, the ghosts groped all the way along the invisible wall, and reported what they found to Li Xian.

"Big brother, this wall actually encircles the entire building."

"Big brother, the sky above the building is also surrounded by this wall technique!"

"Haha, there's an entrance here!" Fat Wu said excitedly.

Before Li Xian could fly over, more than a dozen brothers had already rushed in along the entrance.

"Wait outside, and don't act rashly."

Li Xian commanded the remaining dozens of hundred ghosts, and he himself flew in along the entrance.

"I'll stay with you, I might be able to do you a favor." The old man followed.

"Brother Li Xian must be inseparable from me!" Xiaoqian also followed.

Seeing this, Chang Shiyu flew in without thinking.

Seeing that the iron wolf also wanted to come in, Li Xian turned his head and said loudly: "Be careful that it is a trap, you are guarding outside, don't be trapped, there is no one to answer." ”

Hearing this, the iron wolf had no choice but to stop, stand at the "entrance", and block the rest of the brothers.

"Big brother, the front is blocked again." The dozen or so brothers from before stopped and continued to grope along the invisible wall.

"There's a passage here!"

"There's another passage here!"

"I suspect it's a maze set up with wall techniques." Li Xian said.

"There are so many of us, half of us go through each passage, and half of them can always break through." Xiaoqian said.

The old man said: "That's all!" ”

So the men divided into two routes, and each of them continued along the passage.

They didn't fly far, they were blocked by the wall again, and when they searched again, there were two more passages.

"Sure enough, it's a labyrinth!" Li Xian's head was big for a while, and it was already difficult to break through the maze, but it was even more difficult to break through this invisible maze.

"It's fun, I like to break through mazes!" Xiao Qian said, picked a random channel, and rushed in first.

"Haha! There are two more passages in front of this! ”

"Oops, help—"

Two voices sounded at the same time, and it turned out to be Xiaoqian's voice.

Li Xian looked forward in surprise and saw that there was a Xiaoqian in each of the two passages.

One was groping triumphantly on the invisible wall, and the other was on fire.

"Brother Li Xian, look at the back." At the same time, Chang Shiyu, who had been following Li Xian, exclaimed in surprise.

Li Xian looked back, and Zhao Xinran, who had just walked through another passage, and the group of brothers she led were actually following behind them.

"Xinran, why did you come with you? Is the other passage impossible? Li Xian asked.

Zhao Xinran looked at him with a smile, but he didn't speak, there was an indescribable weirdness.

"What's wrong with you?" Li Xian was about to approach and ask her, but Zhao Xinran's body suddenly caught fire and instantly disappeared.

Li Xian was startled, and hurriedly looked at the seven or eight brothers led by Zhao Xinran.

Unexpectedly, they were all the same as Zhao Xinran, instantly caught fire and turned into nothing.

At the same time, Li Xian heard Zhao Xinran shouting at another passage: "Brother Li Xian, don't-"

The barrier created by the ghost art, although it can block the body of the half-ghost, it cannot block the sight of the half-ghost.

Li looked over leisurely.

saw another passage, Zhao Xinran and the seven or eight brothers she led were standing there well.

But beside them, there was another Li Xian and this group of brothers led by Li Xian.

That "Li Xian" and the brothers he led were also like Zhao Xinran and them here, and they burned.

"Zhao Xinran, I'm fine, I'm here! The people who burned just now are fake. Li hurriedly comforted the panicked Zhao Xinran and them.

"Those who burn can be said to be fake, or they can be said not to be fake." The old man's face was solemn, "I suspect that we have broken into the five-dimensional labyrinth!" I didn't expect Lao Wang's wall technique to reach such a high level! ”

"A five-dimensional labyrinth?" Li Xian was puzzled, "After that fake Li Xian burned just now, the yang energy in my sea of qi was much less. ”

"Stop where you are, don't move!" The old man shouted.

Xiao Qian's body, which was running at the front, lost the most yang energy in the sea of qi, and she realized that something was wrong and had stopped.

Zhao Xinran also found that Li Xian and the others were still staying here, and while relieving their hearts, they all stopped and listened to the old man quietly.

To put it simply, one dimension is a line. There is only length, no width and depth.

Two-dimensional, is a plane. There is length and width, but no depth.

Three-dimensional, on the other hand, is three-dimensional. Ordinary mazes are three-dimensional.

Four-dimensional, one more timeline than three-dimensional. In the four-dimensional labyrinth created with wall techniques, starting from the entrance, there will be one more you at the fork of each passage you pass through.

In the five-dimensional labyrinth, from the moment you step into the entrance, as you continue to advance, there will be an extra person at the fork of each passage, regardless of whether you have passed through this passage or not.
