“……”

Everyone was speechless, this stone gate has been sealed in the ground for I don't know how many years, even if there are abnormal cultivators behind it, I am afraid that only bones remain.

"This thing is very weird, so don't touch him easily." Professor Wen shook his head and said.

"How did you find this stone gate, it's deep underground." Concubine Fu was puzzled, how could she find it from the ground.

There are some things that cannot be detected by technology, such as the rule that above the sky, the scientific and technological product cannot reach the sky, which is not something that ordinary people can understand.

Otherwise, there would not be hundreds of years of scientific and technological development, and no one would have been able to tilt scientific and technological products to fly.

"I found it." At this time, the old man standing beside Feng Hao in the doctor's uniform of the research institute spoke.

Concubine Fu looked at the old man and found that he was not cultivated, could it be like her, who had cultivation but could not be detected by outsiders?

"How did you find out?"

"Professor Xia is an old professor in the research institute, he has been in the research institute for decades, and when he found this place, there was a passage here." Feng Hao said.

Concubine Fu was a little puzzled, this passage was dug recently, so who dug it? How did Professor Xia find out?

"I know you're confused, but we haven't found anyone digging this passage either, and it seems like the purpose of digging this passage is to make people find it."

Concubine Fu thought for a moment and stopped talking.

It's just that her face has changed a little badly, and this stone door doesn't feel comfortable at all.

Who's door will carve a grimace and summon spirits?

Shaking her head, Concubine Fu wandered around here again, she wanted to find something special.

When Concubine Fu walked to other places, Professor Wen and Professor Xia also walked out of the crowd and followed behind Concubine Fu.

"By the way, Professor Xia, what are you doing in the graduate school?" Fu Yifei looked at Professor Xia's old look, and she didn't feel uncomfortable at all because of the grimace on the photo, so she asked out loud.

"Hey...... Of course, it's research, but what can I do without doing this in the graduate school. Professor Xia smiled, laughing a little obscenely, looking like a strange old man next door.

"Oh? What to study? ”

"Studyed!"

“？？？”

Concubine Fu was shocked, there is still such an operation?

Professor Wen on the side also had such an expression, very surprised, what was studied by others, did you mean Professor Xia......

Is it a neuropath?

This is embarrassing, I wonder if this Professor Xia is really the kind that has been studied.

"Do it well, this profession is very rich." Silently patted Professor Xia's shoulder, and Concubine Fu sighed.

So, why did Feng Hao protect Professor Xia just now?

Or, what did Feng Hao think about bringing this professor who was being studied here?

There may be an answer, but Feng Hao didn't say it, and Concubine Fu didn't bother to guess.

The road is finished.

Everything that should be collected by this stone gate has also been collected.

Concubine Fu and Professor Wen are ready to go back to the school, what are the specific things here, you still need to go back to the school to look through the copywriting, and some things are not easy to remember.

For example, what was on this stone door, Professor Wen had no clue at all.

But one thing is for sure, this stone door is too unusual.

Bidding farewell to everyone, the three of them left.

They are not from the Shu City Lord's Mansion, nor are they patients of the Shu City Abnormal Cultivator Research Institute, or they are the subjects of study.

They're just here to find out some secrets, so the rest of the excavation is done by professionals.
