"You can leave Aunt Yun's number." Liu Wenyin smiled lightly.

You don't have to!

"I'm kidding, but I'm actually trying to ask another question."

Su Ze silently put away his mobile phone, not feeling embarrassed at all, being bold and thin-skinned is his motto.

"What's the problem?"

"I just heard Aunt Yun call you Dr. Liu, my sister should be an expert in chemistry, right?"

When he asked this, Su Ze kept paying attention to Liu Wenyin and Aunt Yun's expressions, and found that their faces were a little strange, some surprised, some suspicious.

"How did you guess?" Aunt Yun, who had not spoken all this time, suddenly spoke, and it could be regarded as acquiescing to Su Ze's words.

"Is this still a guess? In addition to evolution, what other experts are worthy of escorting a master like Aunt Yun? Su Ze held Aunt Yun's hand without a trace.

Since the beginning of the evolutionary era, evolutionary development has been a priority over any other discipline, a top priority, and the hope that humanity will regain the dominance of the Blue Star in the future.

Five hundred years ago, when the battle of evolution was over and human life returned to stability, the "biology" textbooks in middle school classrooms were replaced by "evolution" textbooks, and evolution was the only main subject, which shows the importance that human beings attach to evolution.

It is precisely this attention that has enabled mankind to make breakthroughs in evolution over the past 500 years.

Liu Wenyin shook her head at this time: "It's not an expert, but you guessed right, I have been engaged in evolutionary research." ”

Su Ze put away his playful expression, lowered his voice, and said, "I have a question I want to ask, it should be related to evolution." ”

"You say." Liu Wenyin listened carefully.

"I want to know, what kind of situation would make an evolutionary smell?"

"I don't know how to describe it, but it's not the stench of not taking a shower, but an indescribable, unbearable smell...... I don't know if you can understand it. ”

This doubt has been held in Su Ze's heart for a long time...... Well, it's less than a week.

It has only been a week since he crossed over, and he was still in a cell for the first three days.

However, during this time, he has not been exposed to the disgusting stench.

The first appearance of that stench was in Zhao Lingxiao's memory, the mysterious person of the mysterious organization who made a deal with Zhao Lingxiao, a Uncle Matt who was dyed with a colorful explosive head, had a foul smell on his body.

The second time he appeared was in the Rock Prison, Su Ze smelled a foul smell on Zhao Lingxiao's corpse, although compared to the stench on the mysterious person who killed Matt, the stench on Zhao Lingxiao's body was negligible, and it could even be barely covered up with a pungent perfume, but it was indeed the same smell.

The last time it appeared was two days ago, outside the door of the hotel, the stinky old man led two of his subordinates to fight Zhang Fantie, and the three stinking old men all had a strong stench.

From this, Su Ze can conclude that the people of the mysterious organization all have a foul smell on their bodies, but what he doesn't understand is how the stench on Zhao Lingxiao's body came from?

Su Ze noticed that after he asked this question, Liu Wenyin and Aunt Yun's expressions became more serious.

"Have you ever seen someone like that?" Liu Wenyin asked.

"I've seen one or two."

"Next time, stay away from them, they're dangerous." Liu Wenyin said solemnly.

"I've seen it." Su Ze asked, "I want to know what that stench is." ”

After being silent for a long time, Liu Wenyin spoke: "The laws of various countries strictly prohibit the production, sale and absorption of human extracts, do you know why? ”

"In order to maintain social order, reduce human internal friction, and protect the growth of young genius evolutionaries." Su Ze said without thinking.

If there is no protection of the law, an evolutionary with superb skills like Su Ze will be the target of other people's hunting, and if he is killed and made into an extract, it will be far more precious and easy to use than any S-level extract.

"That's just one aspect." Liu Wenyin's eyes were deep and stared at Su Ze, "Actually, after humans absorb the extracts of the same kind, they will contract a disease. ”

"Disease?" Su Ze had a flash of inspiration in his mind, and exclaimed: "So the stench is a manifestation of disease?!" ”

Liu Wenyin nodded and explained: "The evolutionary substances in the extract will modify the body cells of the absorber and rewrite the genes, and absorbing the extract of the same kind is like cannibalism, which is a prohibition engraved in the genes, and the violator will suffer from a special disease that cannot be cured." ”

"Some people think that it is a curse, that it is unethical to absorb the same kind of extract, and some people think that it is the punishment of the god of evolution for them."

"The only symptom of this disease is the foul smell emitted from the body, and the more extracts of the same kind are absorbed, the stronger the stench will be, and it will not be able to be covered, which also makes them have nothing to hide from ordinary people, but to stay away from the crowd and hide in the shadows and darkness."

Hearing this, Su Ze finally understood where the stench on Zhao Lingxiao's body came from.

Zhao Lingxiao absorbed the extract of Princess Zhu Zhi, so he was infected with a foul smell!

Liu Wenyin continued to popularize science: "People who are infected with a foul smell are called 'filthy people', they are not tolerated by the world and are wanted by the authorities. And the filthy people themselves can't smell the stench, so the filthy ones often gather in groups to keep warm. ”

It turns out that filthy people can't smell the stench on their bodies, no wonder I didn't find any memories related to the stench in Zhao Lingxiao's memory...... Su Ze recalled that after Zhao Lingxiao absorbed Princess Zhu Zhi's extract, he didn't notice the stench on his body for half a month, it turned out that he couldn't smell it.

And when Zhao Lingxiao died, he sprayed pungent perfume on his body to cover up the stench, he should have learned about the stench on his body from other people's mouths, but it should have happened half a month before his death, and Su Ze did not have that memory.

Wait a minute!

Su Ze suddenly realized a very serious problem.

Zhao Lingxiao has a foul smell on his body, so as a clone of Zhao Lingxiao, will he also be infected with "foul odor disease"?

He may be the same as Zhao Lingxiao, he has long been stinky, but he can't smell it himself!

Wrong wrong...... Su Ze suddenly reacted, if he also had a foul smell, then he would also become a filthy person, and he should not be able to smell the stench of other filthy people.

But since he smelled the stench of Zhao Lingxiao and the foul-smelling old man, it means that he has not become stinky.

Su Ze breathed a sigh of relief, he didn't want to exude that disgusting stench all over his body.

It seems that the "stench" cannot be cured or replicated, and that his clone has not been copied to the stench.

Through Liu Wenyin's narration, Su Ze has some new understanding of the mysterious organization that hunts and kills him, which is very likely to be a force composed of "filthy people".
