Over the next few days, Chen Chen would use two hours of lunch break and two hours from six to eight in the afternoon to go to the hotel to feed the mice medicine and change the bedding.
The eight mice did not disappoint either. There were no illnesses, fights, or other accidents, which allowed the experiment to proceed smoothly.
It was not difficult to feed these mice. A daily ration of feed was enough. Occasionally, Chen Chen would take out a peanut or walnut kernel, which would make them jump with joy.
However, Chen Chen had spent a lot of money. His monthly living expenses amounted to one thousand and five hundred. Just seven days' rent alone cost him over a thousand.
It was only the middle of the month and Chen Chen was already at a point where he could barely afford to eat in the cafeteria.
"Since there are no problems so far, it means that it's not poisonous."
Seven days later, at noon, Chen Chen went to the hotel right after class.
He took one last look at the two mouse cages. If the conditions allowed, Chen Chen would like to do a withdrawal test, but he could not afford it anymore.
Moreover, he had consumed a pill in the past seven days. Although it was not much, each pill was invaluable since he could not mass-produce it.
Therefore, Chen Chen took out his last supper and let the mice eat their fill.
After that, he took out the tribromoethanol solution that he had prepared earlier and grabbed the mice one by one with his left hand. He let their abdomen face up while his right hand pierced the syringe into their lower abdomen. The syringe passed through the abdominal muscles and slowly poured in the solution.
Tribromoethanol was often used to anesthetize animals. In addition to Chen Chen's intentional overdose, in less than three minutes, the mice collapsed in the cages one by one and entered deep anesthesia.
About eight minutes later, all the mice died peacefully without feeling anything due to the excessive suppression of the central nervous system.
This was the method of overdose anesthesia. It was the most humane method of killing experimental animals.
Well, it was much more humane than decapitation, cervical dislocation, bloodletting, air embolization, and other methods.
After confirming that all the mice were dead, he checked out of the room and bought a bottle of alcohol in a medical supermarket. He chose an empty alley and poured the alcohol on the mice's carcasses.
As a faint blue flame rose, the mice were completely engulfed by the flames. They gradually turned black and were no longer recognizable.
Regardless of the composition of the drug, whether it was a biochemical drug or a traditional Chinese medicine, or even a genetic drug, it was no longer important. After being burned at a high temperature of 500 to 600 degrees, the molecular bonds would be destroyed to the point where nothing would be left.
It could also be considered as holding a cremation for the eight meritorious subjects.
After that, Chen Chen did not return to school. Instead, he grabbed a quick lunch outside, then took the Line 9 subway and rushed to the most authoritative Shangdu People's Hospital in the city.
Although there were no problems with animal experiments, it was better to be safe than sorry. What if the drug was not toxic to mice but highly toxic to humans?
This phenomenon was not unheard of. For example, if humans ate chocolate, not only would they be fine, but they would also be happy. However, if mice ate it, they would definitely be tired of living.
That was why Chen Chen came up with the idea of going out to the hospital to take pills. In the hospital, as long as the pills were not cyanide and paraquat, he could be saved.
Anyone who had taken the subway knew that the signal along the Shangdu subway was terrible. The only thing they could do was make emergency calls, so they installed subway televisions as public facilities.
The programs on the television were mainly news and information.
At this time, Chen Chen was sitting on the subway, watching the real-time news on the television in boredom. There were legal science popularization as well as news advertisements, so he was able to get through it.
Among them, the most concerning was a Good Samaritan incident that had happened not long ago. In Renmin Road, a man was stabbed three times by a vicious criminal in order to stop a kidnapping. Then, he was rescued by the police who rushed to the scene.
As it was just past the rush hour, the subway seemed a little empty. There were only four or five old aunties sitting nearby, holding handbags of church propaganda.
Obviously, these old aunties were going to the church for mass.
"Hey, Renmin Road? Isn't it around here? "
An old aunty took off her shoes and sat cross-legged on the seat, rubbing her feet while sighing. "There aren't many young people like this."
"Seriously, it's hard to get people to give up their seats on the subway. They're always saying that I'm not fit, that I'm on my period, and that I can't do anything about it..."
Another aunty who was twice the size of Chen Chen also sighed.
When the subway arrived at the station, it was around two in the afternoon.
Chen Chen wandered around the hospital alone and finally came to the emergency department.
The Emergency Medical Center was the department that dealt with emergency medical situations. No matter when he came here, it seemed to be filled with a solemn atmosphere.
Ambulances came and went, and from time to time, stretchers clattered through the dark corridor, accompanied by the hurried footsteps of nurses.
Occasionally, a large group of family members would rush over and gather in the corridor, arguing endlessly. Then, they would be escorted to a seat in the waiting area by the security guards.
In such a noisy environment, Chen Chen's arrival did not attract anyone's attention.
Chen Chen sat in the corner of the waiting area, took out a pill that he had prepared, and examined it carefully.
Chen Chen shook his head, took a deep breath, and gently put the pill into his mouth.
He gently closed his eyes.
One second, two seconds, three seconds...
...
"Xiao Jie, Xiao Jie, come to Renmin Hospital quickly, your dad just fainted..."
...
"Hurry, hurry, hurry! Move, move, move, don't block the way, move the door, the stretcher is coming! "
...
"Sob sob sob... It's all your fault. If you weren't driving so fast, would this have happened? If anything happens to Pengpeng... "
...
"Mom, Mom, what's wrong with Dad? When will he come out from that door?"
...
At some point in time, Chen Chen found that his hearing had become extraordinarily sensitive.
Not far away, a woman with a weathered voice was holding a mobile phone, telling her daughter about her husband's condition. She seemed to be choking with sobs.
Outside the emergency room, the moving stretcher made a harsh grinding sound. The nurses kept pushing away the family members who were blocking the way.
In the seats in front of Chen Chen, a couple was talking in a low voice while the woman was sobbing.
Also, the soft little girl next to her kept asking her mother questions. At such a young age, she was gradually understanding something.
These countless voices were mixed together, but they were clearly separated. The syllables of each sentence, the emotions of each conversation, were presented in Chen Chen's mind in detail...
