For Zheng Yongfeng, his biological brother, things are not that true.

Zheng Ke didn't go home at night because she was neurasthenia and was noisy and quarrel in the dormitory. Her roommate often didn't sleep in the middle of the night, disturbing her to rest, so Zheng Yongfeng rented a house for her and occasionally went to have a good rest.

It is not because of Zheng Ke that they cannot get along with their classmates, as those classmates themselves have certain problems.

Zheng Ke finally got into college. In order to have a better future, he studied hard while working part-time. How could he fall into depravity and encounter drugs that he shouldn't touch?

But no one believed what Zheng Yongfeng said.

The school and society both stamped Zheng Ke, but the police had no clues, so the matter had to be left alone.

Since then, Zheng Yongfeng has been traveling to the northwest more frequently, and takes on tasks when he has them, organizes his own network to secretly investigate the drug.

This medicine is called cr2.

In the past three years, Zheng Yongfeng has intermittently found some clues—

1. Cr2 is still being improved, and he has obtained every batch of medicines. Obviously, each batch has a purer effect and better quality. Of course, the price of this type of medicine has doubled every pure degree, and it is becoming more and more expensive on the market and its reputation is becoming more and more famous.

2. Every time cr2 develops a new product, he will find someone to try the medicine. But the people behind the scenes are very smart. They look for people from all over the country, and they specialize in picking those who come from ordinary, inconspicuous, and have no background at home. Some people even disappear in this world and ignore them.

If someone dies, they will deal with it privately;

Those who survive by chance will basically become addicted and will not end up being much better. They have millions of ways to deal with it.

Zheng Yongfeng initially speculated that Zheng Ke belonged to the group of people who were regarded as "test products".

However, Zheng Ke was a college student after all, and the response after his death was quite large.

——What should be a problem when I was asked to do the experimental target.

But, except for the parties involved, they have no way to know.

Si Sheng accidentally learned about this after meeting Zheng Yongfeng. Later, because he sympathized with Zheng Ke's experience, he always paid attention to the news of cr2.

"Because of this batch of cr2, the police followed the clues and passed some relationships with me, things are progressing now."

He didn't say too much detail to Zheng Yongfeng. Si Sheng narrowed his eyes and only gave a final answer, "At the latest, wait for another month, the Lancheng police will close the network."
