Brother Jue calmly unlocked the door. When the key turned into white light and disappeared, he opened the door.

As a result, nothing happened...

At least visually and aurally, there are no shocking scenes that are extremely impactful.

but……

"I'll go...what does it smell like?" Gui Xiao was the first to speak. He had to admit that even though his ability to solve puzzles was rather worrying, his reactions were still very fast and his senses were very keen.

"It's some kind of... oh no... I should say 'various' expired organic solvents." This time, it was Wang Tanzhi who answered him.

"Haha... As expected of Dr. Wang, did you calm down after smelling this smell?" Feng Bujue turned around half-jokingly and said to Xiaotan.

"Hmm...yes." Xiaotan thought for a while and found...that it was indeed the case.

"Very good, let's get going." As Feng Bujue spoke, he stepped through the door, and the investigation of the biology classroom began.

The biology classroom is the smallest room they have ever entered so far. There is a rectangular experimental table in the center of the classroom. Judging from the height of the table, primary school students must stand to operate on it. Perhaps that is why...

There are no seats at all in this room.

There are some exhibits on both sides of the classroom, which are basically soaked or dried specimens; there are some illustrations of animals posted on the surrounding walls, and the illustrations are accompanied by simple text introductions; there is also a wash basin in the corner of the classroom

Taiwan, the smell in the room mainly comes from there...

This time, the players were extra cautious when investigating.

There are two reasons for this. First, opening the door did not trigger any terrorist incidents, but instead made the players feel uneasy. Second, Xiao Tan specifically reminded everyone that expired organic solvents are not only harmful to the body, but may also cause fires.

So, after about ten minutes, the players completed the investigation of the biology classroom. The results are as follows

First, all the drawers around the experimental table "cannot be opened". Various tools, including scalpels, and more than ten different solutions are messily placed on the table; but... on all the bottles containing solutions,

The text is blurry and it is difficult to confirm the nature of the liquid in it.

2. There is no abnormality in the surrounding specimens.

Third, no clues can be found from the illustrations on the wall for the time being, but Brother Jue still read all the contents and memorized them.

Fourth, although this classroom does not have windows facing the corridor, it does have windows facing outside the school; through the window glass, you can see the country roads, telephone poles and trees under the moonlight... everything seems so peaceful, normal, and...

This depressing space in the school is in sharp contrast.

Of course, these two windows are also "sealed by the power of darkness" and cannot be broken.

Fifth, the drain outlet of the wash basin was obviously blocked. There was a lot of dirty liquid accumulated in the pool, and the condition of the bottom of the pool was completely invisible. The only faucet could be turned on, but no water flowed out of the water pipe.

"Okay... please turn off your flashlights." After the investigation and communication, the decision-making work naturally fell on Brother Jue's shoulders, "Well..." He pondered for half a second and said, "Everyone has seen it.

, None of the tools on the experimental bench are 'plot-related' items, so if there are any clues to follow in this classroom..."

Having said this, Feng Bujue turned his attention to the sink, and his intention was self-evident.

"You can't see me...you can't see me..." At this moment, Gui Xiao had already recited the five-character formula in his heart and used diretion mentally.

Unexpectedly, at this time...
Chapter completed!
