More than a decade ago, the professor discovered the phenomenon of soul swapping that occurred in a car accident by chance, and the memories and emotions of the two injured people were replaced with each other, but they themselves knew nothing about it.

Since then, the professor has been immersed in the study of the soul. Later, under some adventures, he really got some research results and successfully deciphered the code of partial soul separation.

When the professor happily announced his research results to the outside world, he was met with countless doubts and ridicule, and many people even scolded him for being a liar and a god.

In the face of such a result, the professor was devastated, and at the same time, L University was also prepared to stop financial support for the professor's research due to external public opinion.

Under the double blow, even the professor himself was shaken by the research, and it was at this time that the mysterious organization approached the professor, who not only promised to provide all the funds needed for the professor's research, but also provided a large amount of information related to the soul.

This sudden turn of events surprised the professor and at the same time, strong questions surged in his heart, because the information provided by this mysterious organization was even more profound and comprehensive than the results of his previous research, and this organization had only one requirement for the professor, that is, after the research was successful, he must use this technology to help him separate another pure soul body from a mixed soul body.

For such a simple request, the professor readily accepted, but he never expected that it was this request that would not only kill him, but also turn the entire laboratory building into a hellish cage.

With the full support of the mysterious organization, the professor's research soon made a breakthrough and entered the final experimental stage.

The first few experiments were successful, and soon the experiment came to an end, and the final experiment to verify the success of the study was scheduled, which was the notice I saw in the lobby of the laboratory building.

The original test subjects were the original two car accident victims who had exchanged souls, and the purpose of the experiment was very simple, that is, to separate the souls exchanged between the two from their bodies, and then reverse them.

But just as the experiment was about to begin, the mysterious organization temporarily demanded that the subject be replaced with another person they had brought.

Faced with such an absurd request, the professor naturally disagreed, but the laboratory at that time was all controlled by a mysterious organization, and under the coercion of these people, the professor had to agree to their request.

The Soul Separation Experiment began with such a hasty replacement of the test subject, and the subsequent accident proved the error of doing so.

Just as the separation experiment was coming to an end and about to succeed, an unexpected happened.

The terrifying thing that was separated from the subject's body was beyond anyone's imagination, and the subject was swallowed by the isolated thing before the experiment could be successful.

The detached soul instead swallowed the physical body of the host, which was unimaginable, and then tragedy occurred.

The people of the mysterious organization were no ordinary people, and after the situation got out of control, they organized people to lock down the laboratory in an attempt to catch the out-of-control devil.

However, it is a pity that although those people are powerful, they are completely worthless in front of the demons created by the experiment, and within a few minutes, the people of the mysterious organization were slaughtered and killed, and the death was horrific, and the flesh and blood almost stained the surrounding walls red.

After killing all those people, the devil did not stop, and all the researchers in the laboratory, including the professor, without exception, died tragically.

Perhaps because of that devil, the professor became what he is now after his tragic death, not only him, but all the victims who died at the hands of the devil have all become similar spirits, but they have different forms.

However, even if they died, their spirits were not at peace, even if they had become ghosts, they still trembled in the face of the devil created by the experiment, and what was even more terrifying was that the devil fed on ghosts.

Luckily, the devil couldn't get too far from the original device, or it would have exhausted its strength, which may have something to do with the fact that the experiment was not completely successful.

However, the day after the experiment's accident, eight evil spirits were born in the experimental building, and they became the devil's minions, hunting down the rest of the ghosts in the building.

As a result, the rest of the ghosts hiding in the building could no longer gain a foothold, and soon, ghosts like the professor began to prepare to escape from this hellish place, and at this moment, all the ghosts were shocked to find that the entire laboratory building was blocked by a mysterious force, and they could not leave at all.

At the same time, a Taoist appeared.

This person is the Tiantong master, nominally, he is the master of the school to practice the house, but in fact, this person is a member of that mysterious organization.

Due to the failure of the experiment, all the people involved in the experiment died, and the organization that had not waited for the results could only send people into the laboratory building again to investigate the situation, that is, this Tiantong master.

These are all things that the professor who has become a ghost has seen and heard with his own eyes.

The devil that was created due to the failure of the experiment seemed to be very important to the mysterious organization, and after discovering the situation in the laboratory building, Master Tiantong arranged a very vicious magic circle in order to change the result of the failed experiment.

Using this magic circle, they plan to seal the failed product of the soul separation experiment, the devil, together with all the undead in the laboratory building, and with the help of the power of the formation, forcibly fuse all the undead and the devil together, and after more than ten years of nourishment, they can get what they want.

This vicious magic circle is the formation that has now sealed the entire experimental building, and its name is the Eight Gates Evil Yin Array.

Hearing this, I was taken aback, and I couldn't help but ask: "Eight Gates Evil Yin Array?" Isn't it the Eight Gates Ghost Binding Array? ”

Yang Mengqing shook his head and said that the Eight Gates Ghost Binding Array was a trap set by Master Tiantong, because it took a long time for the Eight Gates Yin Array to refine all the undead, and he couldn't be sure if the formation would be loosened in the past ten years, and the reason why the fog of Eight Gates Ghost Binding was left was to prevent people outside the organization from discovering the secrets here first.

Master Tiantong left the same document in every area of the Eight Gates, in order to mislead others to break the seal.

Yang Mengqing told me that she met the professor's undead after being injured by me and fake Sydney, and the professor told her everything, she originally planned to stop me, but I didn't expect another accident, in order to rescue Sydney and others, the abnormalities in her body intensified, and she just returned to normal.
