All the way to the scientific research department, there is a pool of about 12 square meters in front of the gate of the hormone laboratory, in which there are several fish of different species swimming idly.

This is the fish used in the experiment, and the hormone produced by the hormone laboratory, oxytocin, will be used for experiments with these fish, and it will be officially put into use after it is determined that it can be eaten by humans.

Lu Yan sighed slightly, even if it was edible, it was impossible to have no effect on the body.

But life is going to be gone, and if you can eat enough, no one cares about these things.

Mu Tang squatted next to the pool to watch, Lu Yan turned around and told her to come to him when she had seen enough, and then entered the laboratory.

Because it is a hormone laboratory, there are no harmful substances, and it is not a confidential experiment, so this laboratory is relatively remote.

Except for a few researchers who occasionally come over, there is basically no one at any time.

Even the security is not as tight as the other key laboratories.

The last time Lu Yan came, they were using these laboratories, and they couldn't help it, they searched too carefully.

This time the laboratory is vacant, and I can finally carefully search for the unreasonable things in this laboratory.

Lu Yan searched along the experimental table while pondering:

This lab is great for storing things you don't want people to see, and because it's not that important, no one will clean it very carefully.

This makes the person who hides things like a tiger.

After searching again, he still found nothing, Lu Yan's eyes scanned these seemingly randomly placed furnishings, and his eyes fell on a corner that seemed to be messy and stacked with equipment.

It was strewn with all kinds of large equipment that didn't need to be sterilized, and there were even stacks of materials and books stacked randomly together.

A thin layer of dust had fallen on it.

Lu Yan's eyes flashed, hiding things doesn't have to be outside, there may be some hidden grid artificially built.

There are no dedicated experimenters in this laboratory, and they are all experimenters in key laboratories who spend their free time researching, so the whole room does not look very tidy.

It doesn't look so unreasonable to put the pile there.

But if you think about it carefully, no matter how normal the experimenter is, he will have the professional ethics he should have, the tables and chairs are placed chaotically, but the experimental data will be neatly stacked.

And putting such a big pile of messy and dusty things there, it invisibly makes people not want to go over, let alone clean it up.

Thinking about this corner is even more unreasonable.

Lu Yan walked over with his feet raised, ignoring the dust on it, like those messy things were moved away one by one.

A damp musty smell floated up his nose, Lu Yan frowned, and the speed of his hand increased.

In a few moments, all of these things had been removed, revealing empty corners—

Nothing.

The corner was so dusty that even the walls were covered in dust, and there was a nest left over from a spider in the corner, which was also covered in dust.

What looks normal can't be normal anymore.

Lu Yan glanced at it, and his gaze froze.

It seemed that the dust on the wall was just a camouflage, because he noticed that the color of the wall skin was different under this layer of gray dust.

Most of the wall skin has turned a little yellow due to the long time, but there is a blank spot in the lower position-

This is freshly brushed.

Lu Yan bent down, curled his fingers and tapped, it was not a hollow sound, but it was different from the normal sound of hitting the wall.

There's something under this wall.

Just as he took out a crowbar from the space and was about to tap on the wall, a voice suddenly came from behind him with hesitation:

"Excuse me...... Anyone? ”
