"You must teach this Dean Jin a lesson," Yang Qing said secretly in his heart.

As the saying goes, the master has his own affairs, and the disciples obey their work, this Dean Jin actually thinks about his teacher, and Yang Qing must not let him go.

During the day, Yang Qing was equipped with a genetic virus liquid that could change the color of the mouse's body, and now Yang Qing is ready to use this genetic virus liquid to teach Dean Jin a lesson.

There are still some differences between the gene fluid used for experiments with mice and those used on humans, but the difference is not too big, and Yang Qing used one night to configure the virus liquid for humans.

Carefully put the configured virion into the incubator, Yang Qing closed the door of the incubator, and the virion in the incubator continued to replicate to increase the density.

While the virus liquid was replicating itself, Yang Qing left the laboratory and called a car to go to Dean Jin's community.

Dean Kim's neighborhood is not too far from the school, and the car stopped at a coffee shop outside the neighborhood after just over 10 minutes.

After buying a cappuccino and a sandwich in the coffee shop, Yang Qing walked into the community.

Yang Qing walked around the community for a while and saw a place where garbage was piled up.

Finding a corner opposite the garbage dump, Yang Qing squatted down, eating a sandwich and drinking coffee while staring at the garbage bin in the distance.

This time point is around 7 o'clock in the morning, which is the time to go out to work, and it is also the time to throw out the garbage, and from time to time someone will put the garbage in their hands into the corresponding garbage can.

Time passed minute by minute, and the sandwich that Yang Qing bought had already been eaten, and only half a bite of coffee was left.

"Why hasn't this Dean Jin come out yet!" Yang Qing looked at the time, it was almost 8 o'clock.

At this time, the weather was still very cold, and Yang Qing had been squatting here for almost an hour, and his feet were a little numb.

Standing up from the ground, Yang Qing stomped his feet on the spot a few times.

At this moment, Yang Qing's eyes suddenly lit up, and a figure emerged from the side of the road, carrying two garbage bags in his hands, and this person was Dean Jin.

Seeing that Dean Jin finally appeared, Yang Qing couldn't help but lean down slightly, staring at the garbage bag in Dean Jin's hand with the corner of his eye.

The two garbage bags were disposed of separately by Dean Jin in different colored garbage bins.

Yang Qing waited until Dean Jin walked away, and then walked towards the red trash can with the finished coffee cup in his hand.

There are two colors of bins, a green bin that represents recyclable waste, and a red bin that represents non-recyclables.

Coming to the red trash can, Yang Qing opened the garbage lid, and then took out the trash bag that Dean Jin had just thrown away.

Carrying a garbage bag, Yang Qing walked towards the public toilet next to him.

"Bang ......"

Closing the door of the toilet cubicle, Yang Qing opened the garbage bag in his hand.

As soon as he opened it, a pungent smell came out, Yang Qing held his breath and poured out all the garbage.

The next moment the flavor is even bigger.

Yang Qing used the coffee paper cup in his hand to play back and forth in the garbage heap, and after a few fiddles, Yang Qing saw what he wanted.

It's a used condom.

At this time, Yang Qing reached into his pocket and took out a straw and a glass vial.

Putting the straw into the condom, Yang Qing pinched it a few times, then took it out and put it in front of his eyes, and at this time he could see some viscous liquid in the straw.

Dripped the liquid from the straw into the glass vial, and Yang Qing screwed the lid of the glass vial.

……

Back in the laboratory, Yang Qing opened the incubator and took out the virus stock solution cultured inside.

Then Yang Qing took out the small bottle containing Dean Jin's bodily fluids from his pocket.

The next step was to edit the DNA fragment of Dean Kim.

The human DNA genome is very complex, everyone has a different genetic combination, but more of the same DNA fragment, the virus liquid made by Yang Qing is the virus agent, that is to say, this virus liquid can work on all human beings, if you directly use the virus stock solution to deal with Dean Jin, there will be a great risk, it may affect other people, although this virus stock solution is not infectious, but the virus is difficult to control, you don't know when he will evolve on his own, used to adapt to the environment.

In order to eliminate this risk of affecting other people, Yang Qing is about to obtain Dean Jin's DNA, fortunately, it is too simple to obtain a person's DNA, human saliva, **, and all kinds of excrement can be extracted, but it is too simple to extract DNA from Dean Jin's household garbage.

As time passed, Yang Qing's DNA editing of Dean Jin was also nearing its end.

A tube of white liquid was held in front of Yang Qing's eyes, and he shook it gently, and the corners of Yang Qing's mouth smiled slightly, and it was finally completed.

This tube of white liquid is the virus liquid specifically for Dean Jin, and unlike the virus stock solution, this tube of virus liquid will only be effective for Dean Jin alone, and there is no difference between it and boiled water for others.

At this time, Yang Qing couldn't help but feel a wave of sleepiness when he looked at the liquid in his hand, and looked at the time, it was already more than 12 o'clock in the morning, and after staying up all night, Yang Qing couldn't help but feel a little tired.

However, this is not the time to sleep, and Yang Qing still has something to do.

A small spray bottle was taken out by Yang Qing, the bottle was very small, only the thickness of a thumb, and the length was about the same as an index finger, with a red nozzle and a white bottle body.

This is what Yang Qing bought from a roadside convenience store when she came back, and it was a spray bottle that ordinary girls use to hydrate their faces.

Unscrewed the bottle, and Yang Qing put the virus liquid in.

Putting the spray bottle containing the virus liquid into his pocket, Yang Qing glanced at the test bench, and all kinds of things that had just been used in the experiment were placed in a mess on the test bench.

"Let's clean up when we come back!" Yang Qing said secretly, he was a little sleepy now, so he would finish his business first and clean up the laboratory when he came back.

Thinking in his heart, Yang Qing turned around and left the laboratory.

Along the school's bluestone path, Yang Qing soon arrived at the office building where Dean Jin was, as a dean, Dean Jin naturally had his own independent office, and this office was very large and conspicuous.

Yang Qing easily found an office with the Jin Yongshun brand, and this Jin Yongshun was Dean Jin's name.

Out of the corner of his eye, he looked around at the surroundings, and there was no one nearby at this time, Yang Qing took out the spray bottle in his pocket with his right hand and held it in the palm of his hand, and then walked towards Dean Jin's office.

When passing by Dean Jin's office, Yang Qing pressed the spray bottle in his hand, and with the words "Snort... ...... sneer", the virus liquid in the bottle was sprayed onto the doorknob.

Yang Qing didn't have any stop, as if he was passing by, coming out of the office building, Yang Qing's spirit relaxed, and the next moment a wave of sleepiness hit.

"Sleepy!" muttered, Yang Qing walked towards his dormitory.
