Lu Xiaoye, the most inconspicuous young master of the Lu family in Hong Kong Island. He has the delicate face of a buttermilk dog and a soft and pure personality. He has to apologize for three minutes even if he steps on an ant. The family succession test is about to take place, and the clan elders kick this good-for-nothing young master into the world of Hong Kong dramas, forcing him to complete three assassination missions, otherwise he will be stripped of his surname and kicked out for life. But Lu Xiaoye fainted when he held a knife for the first time. When he was desperate, a random voice suddenly sounded in his mind - the "contrast system": the greater the contrast between behavior and appearance, the greater the improvement in strength. He was afraid of blood and gritted his teeth and closed his eyes and fired. He was soft-hearted and lifted the table with tears and smiles. He was so cute that he pushed the gangster to the ground with his backhand and asked in a tearful voice: "Do you still want to bully me?" The world of black and white in Hong Kong TV series is completely chaotic: the underworld has placed a bounty on his head, the police suspect that he is mentally ill, and the cousin in the family who wants to seize power quietly handed him a reminder. While bearing huge family pressure and being pursued by various Hong Kong film-level villains, Lu Xiaoye could only swallow his tears, hold the system in hand, and start a counterattack that made everyone laugh and the villains cry.
