Who poisoned Ma Shuai?

Ma Shuai was poisoned by chef Zhang Tongsheng. Of course, Zhang Tongsheng is just an ordinary person, and he doesn't have that much power. So Zhang Tongsheng poisoned Ma Shuai at someone's instigation, and Zhang Tongsheng was just a little chef.

Certainly not so big ability to come into contact with Gao Mingyuan and the forces behind it, so it can only be directed by someone inside the Public Security Bureau, and this person should be He Yun.

The death of Ma Shuai.

In the middle of the police station, he broke his little finger and sent a message to Gao Mingyuan. Gao Mingyuan didn't expect that his old man Ma Shuai would make low-level mistakes. Ma Shuai worked under Gao Mingyuan for many years and has never been arrested by the police station.

Gao Mingyuan was very flustered when he learned that Ma Shuai had been arrested. He was afraid that the police would pry open Ma Shuai's mouth, so Gao Mingyuan began to plan how to make Ma Shuai shut up forever, but before Gao Mingyuan committed the crime of killing Ma Shuai, Ma Shuai was already dead.

Besides Gao Mingyuan, there are other suspects who killed Ma Shuai. DJI and Ma Shuai have worked together for many years, and the relationship has been bad. Netizens have speculated that DJI is likely to take this opportunity to kill Ma Shuai, and Ma Shuai's status will be improved after his death.
