The role of Chen Mingsheng has no prototype. He is the original character of the novel, but this character is the epitome of tens of millions of anti-drug policemen in real life. Chen Mingsheng is the hero in the novel The Unknown Story. He used to be a drug policeman, but after losing a leg, he became a taxi driver.

After that, he went undercover. The last undercover operation, although successful, was assassinated and the body was injected. The amputation of his right leg initially led to his poor health. Just when everyone thought he was in good health, the toxin eroded his nerves and caused him to die of a heart attack.
