Hearing this news, both Xu You and Lin Shi looked excited.

This not only proves the high accuracy of the quantum computer simulation model, but also brings greater possibilities to the subject of rebirth of severed limbs.

"Great, Professor Gao, we can prepare for the next animal experiments. We will start with small white mice first, and then primates that are closer to humans."

"Okay, Academician Xu, this is all on us."

Xu You is not good at the specific operation of medical experiments, but with a professional expert like Gao Mi present, Xu You doesn't have to worry about it.

In the first phase of animal experiments, the experimental group will amputate multiple mice, and use the previously screened chemical molecule combinations to test the possibility of stem cell reversal and regeneration of severed limbs.

The reason why the experiment was done with white mice first is because the white mice have many advantages and are very suitable for use as experimental animals.

First of all, mice are small in size, do not take up too much space, and are relatively simple to raise.

Secondly, the mice we use for the experiment are all scientifically cultivated mice, with very small differences among individuals, which are very suitable for scientific controlled experiments.

Of course, the most important point is that mice and humans are both mammals, and their genetic similarity is extremely high.

As long as the experiment on mice is successful, the same treatment plan will most likely be used on humans.

After careful preparation, the first phase of animal experiments officially started.

For some reason, Xu You had a strange feeling when he saw those mice whose limbs were amputated for experiments.

"Lin Shi, tell me, is this method of experimenting with mice really an appropriate method?"

"Why, teacher, isn't the white mouse the most suitable species for experiments?"

Lin Shi didn't understand what Xu You said, so Xu You could only continue to explain:

"I don't mean this aspect, what I mean is, is it a matter of course to use mice to do experiments?"

"Teacher, you are not so holy, are you? Usually when we eat meat, we don't have so much emotion."

There is indeed no problem with Lin Shi's words, but Xu You still feels that this is not the same thing.

Xu You thought for a while, but still didn't continue to ask.

It is more appropriate to study this kind of problem with Lu Zhiyao.

After the experiment in the evening, Xu You went to pick up Lu Zhiyao and go home together. On the way, he and Lu Zhiyao discussed the issue that came to mind today.

"Yaoyao, tell me, is it reasonable for us to use mice for experiments?"

Hearing Xu You's question, Lu Zhiyao was thoughtful, and asked instead:

"Then you think, if this is unreasonable, where is the unreasonable?"

"To be honest, I can't tell you clearly. I know this kind of thinking is a bit inexplicable, but when I think about it deeply, I always feel like there is a cool breeze on my back."

"You mean...you worry that one day human beings will face a similar fate?"

Lu Zhiyao thought about it for a second, and suddenly understood what Xu You was worried about.

"Yes. If there is an extraterrestrial race that is far more powerful than us and thinks the same about us, then we will be like mice in their eyes. How desperate will we be at that time? "

Thinking of this kind of situation that might happen in the future, Xu You said not to worry, it was impossible.

In the universe, there is a high probability that humans are not the only intelligent life, including some unsolved mysteries on the moon, which still have no clear answers until now.

"I think, from different angles, this matter can have different views. If emotions are not considered at all, then this universe is based on strength. The race with the strongest strength can do whatever they want things."

When Lu Zhiyao said this, his expression was very calm.

On the earth, human beings are undoubtedly such a race, standing on top of all other creatures in the world and dominating the entire earth.

All actions of human beings are for the benefit of human beings themselves.

Even the so-called protection of animals and plants is for the more stable operation of the earth's ecosystem and for humans to have a better living environment, not just for these animals and plants.

Only for those pets, humans will treat them like friends.

At this time, Lu Zhiyao changed the subject.

"However, human beings are not an emotionless animal. Most human beings not only have feelings for humans, but also have feelings for creatures other than food. Just like the kittens we often feed, we have feelings for them. Never had any cruel thoughts."

"So Yaoyao, what's your point of view?"

"As long as you don't feel guilty. We don't do any cruelty to the rats, except for the necessary research. As far as I know, when we experiment with the rats, there is a '3R' principle?"

The 3R principle referred to by Lu Zhiyao, that is, "reduction, optimization and replacement", should minimize the number of organisms used in experiments and minimize the pain they suffer when it is not necessary.

"Yaoyao, I seem to suddenly understand."

After Lu Zhiyao's coaching, Xu You felt a sense of enlightenment again.

"Well, do you have any new ideas?"

"I think that when we become the strongest race, we can't be bullying, and we can't take everything for granted. Of course, this doesn't mean the Holy Mother. It doesn't matter if it is necessary to eat or experiment, as long as its starting point is not bad. of."

"More importantly, in order to let the right to choose and decide in our own hands, we must become the strongest race, and we must not put our fate in the hands of other races."

When Xu You thinks about these issues, he is both emotional and rational, and is not limited to a certain angle.

"That's right, the so-called benevolence and righteousness are not enough, strength is the premise of all this. And when you have the strongest strength, you must not lose your heart. Tyrannical races will eventually perish. "

After these thoughts, Xu You's level of understanding of this issue has improved a lot.

However, this did not affect the progress of the entire experiment. Next is the time, the experiment is still going on as usual.

"Academician Xu, we have detected the emergence of pluripotent stem cells responsible for the growth of hind legs in some mice. If all goes well, these amputated mice will slowly grow new hind legs."

"Well, that would be great. I really hope these mice can regain their health."
