"What's wrong?" The player's companions heard the sound and turned around to ask in confusion.

The player looked ugly and said with lingering fear: "It's okay, it's just that a big rat suddenly jumped out and scared me."

"It's just a mouse. You're too cowardly." His companion laughed.

"I saw that the mouse was quite big. It was different from ordinary mice." The player who was laughed at blushed a little and couldn't help but defend himself.

"No matter how big it is, how big can it be? It's just a mouse. Is it possible that it can be as big as a cat or a dog?"

"Let's go, let's go look for clues elsewhere."

His companions didn't pay much attention to him, they just thought he was timid and a mere mouse could scare him.

Not long after a few people left, there was suddenly some movement on a relatively soft land.

A lot of dirt spurted out from the outside, as if it had been pulled apart by something, and a small hole suddenly appeared.

"Chi chi chi chi..." From inside the cave, there were faint sounds, and there seemed to be several pairs of unknown eyes glowing green inside.

…

On the corridor of the teachers' dormitory building.

Su Tingyu and Dr. Li Li looked at each other.

Su Tingyu suddenly laughed and raised his hand to touch the tip of his nose: "I have a cold recently and my nose is a little stuffy. Either I can't smell it, or I often smell the wrong smell."

"Doctor, I hope you don't mind."

For a while, the atmosphere seemed to relax a bit.

Dr. Li Li's face was slightly sullen: "Since you are sick, you should have a good rest and stop wandering around."

"Doctor, then we have made an appointment. I will come see you again tomorrow and then we will go to the laboratory together."

"Of course." Dr. Li Li nodded slightly, with no emotion or anger on his face.

Su Tingyu took one last deep look at Dr. Li Li, smiled harmlessly, and left.

After Su Tingyu came out, the three men with glasses hiding nearby quickly came over and asked:

"how's it going?"

"Is there any progress?"

Su Tingyu did not answer, but changed the topic: "Let's go somewhere first."

"Where?"

Su Tingyu replied: "Laboratory."

Hearing this, the three of them were a little surprised.

"Laboratory? The doctor told you the location of his laboratory?"

"Ahem..." Su Tingyu felt a little guilty: "I made a mistake, let's go, let's go over there first."

When completing the previous task, Su Tingyu only went to the fifth underground floor and had not seen the other floors.

But this time... I don't know if the laboratory is still in this "space".

…

[Copy time: 14:00]

At two o'clock in the afternoon, all players' panels popped up:

[Good afternoon, everyone! The comprehensive science examination questions are being sent, please check them! 】

"The questions for the Comprehensive Science Examination are coming soon."

"His grandma is such a bear. I've finally waited. There's only one last subject left, so I can leave this ghost dungeon!"

"..."

Most of the players were very excited and eagerly looked at the refreshed content below.

[Topic: Campus Disease]

[Content: In the past, the beautiful and warm Jincheng University was a place of pilgrimage that countless students yearned for. It gathered the most advanced teaching equipment and top teacher resources. But suddenly one day, one after another on campus, there were people who fell ill for no reason and became critically ill.

Finally, due to pressure, Jincheng University was forced to close the campus and stop enrolling students... The originally lively and peaceful campus gradually became an existence that could not be avoided]

[Requirements: During the examination period, do not be infected with dementia, and contain the number of infections ≤ 100W]

"What...is it talking about here?"

"What disease?"

Just as the players were lost in thought.

From different locations on the campus, screams of surprise suddenly rang out:

"Holy crap! Rats eat people!"

"Get out of my way! Ahhhh... why is this mouse so crazy?!"

"..."

Throughout the campus, some mice, cockroaches, centipedes, snakes, flying insects that were originally hidden in dark and inconspicuous corners have all undergone strange changes.

Not only has its size increased several times, but it will also attack the nearest player if it disagrees with it.

At this time, the players’ panels were refreshed again:

【Number of infections: 8W】

【Number of infections: 8.04W】

【Number of infections: 8.072W】

【……】

"What is this number of infections?!"

"Fuck! Be careful!"

"..."

…

And at this time.

Su Tingyu, who was heading to the laboratory, not only received the contents of the comprehensive science examination, but also received one more...

[Please note! Players such as ‘Not Extraordinary’, ‘Old Camel’, ‘Sad’ and ‘Angel Su’ trigger a hidden plot - a failed experiment]
