In the secluded living room, a hazy yellow light spills out from under the lampshade, illuminating the central area.

There, the case has been cleared up by Tang Qi.

All that was left was a dagger, and the dagger-pinned Essos Ghost Grass, or Professor Rick Cassel, with a glass of water next to it.

The two are engaged in a strange conversation.

Tang Qi gained insight into the cause of the serial tragedy at Messer University, and then brought back the real "culprit", that is, Professor Kassel, who had become an active shadow pachycephalic fungus, of course, not because Tang Qi sympathized with his plight.

This old professor, whether at the legal level or at the moral level, does not deserve sympathy.

The reason why he was brought back was naturally because he had what Tang Qi needed.

Moreover, there is more than one.

Tang Qi's gaze slowly withdrew from the pile of notes and manuscripts, then looked at the hyoperium and asked, "Where did you get your knowledge of secret medicine?"

If Professor Cassel had been a human at this time, he would probably have been horrified immediately when he heard this question.

This is the biggest secret of his body, and if he is revealed in one word, he will naturally change color.

It's a pity that he's just a weird plant now.

I could only subconsciously shake the black and slippery tentacles, and then I realized that I was in a situation now, and I didn't plan to hide anything, so I wrote an answer on the desk.

"When I was inspecting a shipwreck from the thirteenth era of the old calendar, I accidentally found some non-perishable books, which recorded a lot of secret medicine knowledge, because it was a thunderstorm that day, except for me who was willing to clean up those things, the other experts went to rest. ”

"I was very interested in that knowledge, so I studied it all night, but unfortunately the next day was the scorching sun, and when the books hit the sun, they burned out in an instant, except for a part of the memory in my mind, and the knowledge was completely gone. ”

"According to my later research, those books are likely to have been circulated among several mysterious tribes that were hostile to the ancient Mayan civilization, and the identity of the owner of the wreck is not simple, but I can't find out because of the old age. ”

In contrast to Donch's short question, Professor Kassel's answer was detailed.

Without thinking too much, Tang Qi asked again, "In addition to the knowledge of secret medicine, do you have other knowledge of occultism?"

"Nope!"

"In addition to that accident, although I have encountered some strange and mysterious events in other expeditions in my life, they have all been solved by guns in the end, and I am not gaining more knowledge about it, although I am also aware of the existence of mysterious realms. ”

"It's just that I don't want to give up my status and reputation, so I haven't revealed that I have secret medicine knowledge and broke into that unknown world. ”

Reasonable explanation, Tang Qi said silently.

A follow-up question, Tang Qi did not say it.

He wanted to know what level Professor Cassel had advanced his secret medicine to, such as whether there were any successful promotions to the profession, and to advance the profession, he needed to successfully concoct those secret medicines in order to obtain professional certification.

The corresponding profession of secret medicine, as far as Tang Qi knows, should start with the "secret medicine apprentice", and then the official "secret medicine master".

However, since Professor Cassel has not really entered the mysterious side, there is no need to ask these questions.

Tang Qi sat on the sofa, silently thinking.

Professor Cassel's words should be true, at this point, there is no need for him to deceive himself, and judging from the fact that he recklessly used the curse potion to turn the female teaching assistant and the captain of the guard into spider monsters, it is obvious that he is not a mysterious person.

As long as there is a little mystery involved, you should know that in terms of supernatural power, the official is the truly terrifying side.

In fact, even without Tang Qi's intervention.

The serial murder case in Mercer University will eventually be solved smoothly.

Only then will the influence inevitably expand to a certain extent, attracting official forces to intervene.

At that time, Kassel, the culprit, will end up extremely miserable.

In this respect, Donch is Kassel's savior.

As soon as he thought of this, Tang Qi suddenly got up slowly, stood in front of the desk, reached out and grabbed the dagger, and then pulled it out directly.

But he heard a soft sound of "snort", and a few drops of black liquid rushed out of the activated halterium fungus with Tang Qi's movements, splashing on the desk.

However, Rick Cassel, who was freed, did not move, like a big black octopus, lying on the desk, waiting for Tang Qi's disposal.

Wise man!

Tang Qi silently gave an evaluation, and then without delay, the next moment he said the content of the transaction initiated by him.

"Professor Kassel, I can find you a body that is perfectly suitable, and I will perform the ritual for you, chant the incantation, and give you a chance to start your life again. ”

Hearing this, Cassel did not show any excitement.

Instead, he waited quietly, and sure enough, Tang Qi's voice continued to come.

"In exchange, you need to pay some price, the only thing you have to trade right now, your ...... Knowledge!"

"Secret medicine knowledge, you have to trade all the secret medicine knowledge you accidentally obtained to me. ”

"Since you can get the Essos Ghost Grass from the wizards of the Sahar continent, then you should also know how to cut your own soul, as long as you inject all your secret medicine knowledge into a soul fragment and cut it off, we will complete the transaction. ”

"Of course, you can choose to refuse, and I will send you directly on your way to kill the real culprit of a serial murder, and I will not have any burden. ”

"Alternatively, you can choose to deceive me when you cut it, but if I find out, I'll still kill you. ”

After saying that, Tang Qi stood to the side, quietly waiting for it to make a choice.

On the surface, I couldn't see any excitement or other expressions from Tang Qi.

It seems that the secret medicine knowledge is not important to Tang Qi, and the current transaction is just something he does casually.

Because of the contact between the two sides, Tang Qi had the absolute upper hand from the beginning, although Professor Kassel was a smart person, but in his opinion, Tang Qi, a high school student, may be a mysterious veteran.

Crucially, it doesn't really have a choice.

On one side is complete death!

On the one hand, it is to pay for the knowledge of secret medicine in exchange for a new life!

As long as you are not a fool or a madman, you can make the "right" choice.

Sure enough, when the countdown in Tang Qi's heart was carried out at three, the "black octopus" on the desk moved.

Under Tang Qi's gaze, it slowly raised one of its smallest tentacles.

"Squeak ~ Squeak"

The simple action seemed to cause great pain, and it began to scream again as it would have been before the rat was trampled to death.

Gradually, in Tang Qi's sight, the short black tentacle began to redden, and wisps of red light continued to pour into it, revealing a color like a red-hot soldering iron.

At the same time, under Tang Qi's eyes, a special interface jumped out.

Fragments of information flowed by.

By the time the last shards passed, the black tentacle was glowing red, and Kassel's screams probably meant that the people living in the small building were perverts who liked to abuse rats.

"Snort~"

Tang Qi struck, his sharp dagger slicing through the air, and at the same time slicing through the tough tentacles.
