As if hidden in another time and space, this door slowly appeared from the top to the bottom, and in the center of this arched door was not completely empty, but there was a sparkling light blue light curtain, as if on the other side of this light curtain was another world.

"It's amazing, it's amazing, it has to be the greatest discovery of the century!" Professor Han couldn't help but take out his camera to take pictures, which are valuable images.

He was sure that if these materials were to be published, they would cause a huge repercussion in the academic community, and even some conventional science would be completely broken.

"Discover the ghost gate, mission accomplished!" When the arch was fully revealed, the principal prompted them to complete the first exam question.

This task is really simple and a little outrageous, they just waited here, solving a small imp who is not very powerful, and this door appeared on its own, they originally thought it would be complicated.

But this also shows from another point of view, the second task will be very difficult, according to the content of the task, it can be inferred that someone wants to open up the two worlds of humans and ghosts, so that the two worlds can be completely integrated.

Once this happens, you can imagine what will happen. If I guessed correctly, that little ghost should have escaped from this door, but obviously, not all ghosts can come out of it, otherwise the world would have been chaotic a long time ago.

Just as everyone was thinking about whether to pass through this door, the sound of chaotic footsteps came out, and the people they had met during the day actually gathered towards this place, as if they had been summoned by an invisible force.

The people still ignored them, but they rushed in the direction of the gate in a daze, and at this time, some glowing orbs appeared on the other side of the door.

The orbs seemed to be striking the curtain of light, but the curtain was so tough that no matter how much they collided, it only made ripples on it.

"What the hell is in there?" Xu Lang couldn't help but shrink his neck.

"What else could it be, something from that world." Compared with the things on the other side of the door, Yu Hao was more interested in that door, the top of the door was written in a certain language, and there were some very gorgeous patterns on the door frame.

But the most important point is that in the center of the top of the door hangs something that looks like a gossip mirror, and that light curtain is projected by that gossip mirror, and it is that gossip mirror that completely separates the human world from the ghost world.

Yu Hao jumped and jumped on the door frame, reached out and touched the mirror, and the function of the school emblem immediately told him what it was.

Kunlun Mirror (Pseudo): An imitation of the Kunlun Mirror, which is engraved with the Taiyi Xuan pattern, which has the divine power to communicate the two worlds of heaven and man and break the gap between time and space. However, many years ago, the mirror was lost, and its whereabouts have not been known since. Rating: S.

"This is actually the Kunlun Mirror, one of the top ten artifacts!" Yu Hao was surprised, although he didn't know how strong the real Kunlun Mirror was, but even if even this kind of forgery had an S-level evaluation, I'm afraid that the real thing is at least SSS or even the only level prop, right?

"This thing can communicate the two worlds of heaven and man, and naturally it can also communicate the two worlds of humans and ghosts, and it is placed on top of this ghost gate, I am afraid that this world was made by a character similar to an immortal a long time ago."

"Everyone, stand back, don't hurt those people, their bodies are not dead yet!" I don't know if those people will attack them, Yu Hao and they simply chose to wait and see.

The first man finally walked up to the light curtain, and he stretched out a hand and put it on the light curtain, which was actually only slightly resistant, and then leaned through the light curtain.

Suddenly, countless balls of light on the other side of the light curtain scrambled towards the pair of hands, and one of the balls of light managed to defeat the other competitors, it burrowed into the man's hands, and then entered its body.

That person trembled, and his eyes, which had lost their brilliance, suddenly appeared with a green light, just like Lin Zhenghui just now!

"Oh no, those goblins are possessing in this way, stop them, don't let those people pass!" Yu Hao took the lead in rushing forward, pinching the possessed guy just now, and the power of death was directly instilled into its body.

The ghost creature suddenly let out a miserable scream, Yu Hao's necromantic power was much stronger and much stronger than Sun Mengqi's, and the level of that little ghost was at most F-level, and under the restraint of this law, there was almost no resistance and disappeared.

It seems that because the possession was not long, the person just collapsed, and the vital signs were still intact.

More than a dozen people immediately blocked the door, their strength was much stronger than these people who had lost their minds, although there were hundreds of people, but none of them could get one step closer to a ghost door.

"Well, why do you bother? Doing so can only organize these little ghosts to enter the world in advance, and it won't change anything at all! At this moment, a voice came from behind them, and an old man dressed in a somewhat ancient style actually walked out of the light curtain.

Yu Hao just wanted to make a move, but the yellow talisman on his body didn't move, this old man was not a ghost, but a person!

"Who are you?" Yu Hao still didn't let his guard down, although he was alone, Yu Hao felt that there was not a weak power in his body, and this power was actually somewhat similar to his necromantic power!

"Oh? You also have the power of that world in you? It's rare! The old man also seemed to be aware of this, and showed a meaningful smile to Yu Hao, "I am the guide!" ”

"Guide?"

"Or you can make me the manager of this door, my task is to send the damned living to the world of the dead, you can call me an immortal old man."

This self-proclaimed immortal old man didn't seem to have any ill will towards them, and he came out of that door, and he must be a very special existence in this world.

"Immortal Elder, what do you mean by what you just said? What does it mean that we can't change anything at all? Sun Zihan asked.

"Do you know what that is?" The old man pointed to the Kunlun mirror imitation on the ghost gate and said.

"That's the Kunlun Mirror."

"Oh? You know? The old man was a little surprised, "The Kunlun Mirror is used to isolate the human world from the ghost world, but its power is getting weaker and weaker, and it will soon be unable to continue to maintain, and when its power is exhausted, it will be the time when the world is completely connected!" ”
