After the destruction of the Chen family, the orphan Chen Tianyang is left wandering the streets, forcibly dragged home by Long Jiang's richest man, Long Zhenyun, to be his son-in-law: If you are a dark horse, your old man will boost you; if you are not a dark horse, even if forced, you will be boosted into a dark horse! Everyone laughs at him as a good-for-nothing unworthy of Long Jiang's number one beauty Long Wanxin, little knowing that this beggar-like youth is precisely the dragon-slaying youth who single-handedly fought the evil dragon Zhujiuyin and destroyed the Tianming Sect in a single night, as well as the Supreme Master of the Three Saints Gate. Grandfather Long is poisoned and paralyzed, and he extends his life with a single needle; his mother-in-law suffers from a terminal illness, and he secretly applies needles; the Wu family sets a trap to harm the Long family, and he leads the Tiansha Gate to flatten the enemy nest. Everyone is waiting to watch a joke, until his identity is revealed, and those who insulted him in the past all kneel to the ground and tremble.
