He's an undercover cop. She is the daughter of a drug lord.
He sneaked into the Dongsheng Group under the name of a dead man, and packed drugs, transported raw materials, and became brothers with drug dealers in the drug manufacturing den every day. For three months, every second was on the edge of a knife. Everyone thought he was Qian Hu, a Ma Zai who ran from Yunnan.
Only Long Qianyu glanced at him.
She looks cold and reclusive, but she is trying to find out the real cause of her mother's death. The person the clue points to is Su Yichen's colleague in the police force - a mole who has worn a police uniform for more than 20 years.
He helps her investigate the case. She covers for him. Two people are walking on the same tightrope. Whoever is tempted first will fall first.
But the one who fell was not alone.
The drug "Crystal Monster" is flowing into cities across the border. Su Yichen must stop this shipment before his identity is exposed. But when he actually completed his mission and returned to the police force, what awaited him was an internal review, the death of his comrades, and an empty room.
Long Qianyu left. He left him an old silver bracelet and a message: "Life will never come again. I wish you peace for the rest of your life."
This is the story of an undercover cop.
It is also a story about a drug lord's daughter exchanging twelve years of hatred for "the rest of an ordinary person's life."
The real ending is not to die together - it is that you obviously win, but there is a missing corner in your heart that can no longer be filled.
