The Dragon in the City: The Immortal Son-in-Law Returns tells the story of Lin Chen, former captain of the Dragon Blade squad, whose name once struck fear into the hearts of the underworld. After a brutal mission leaves him disillusioned, he retires, conceals his identity, and becomes a live-in son-in-law to the Lin family of Jiangcheng, enduring three years of humiliation. He once killed mercenaries with his bare hands and lay in wait on frozen plains to take out targets, yet in the Lin household he is treated like dust, scorned by his mother-in-law, ignored by his wife, and endlessly humiliated by his romantic rival, Zhang Hao.
By chance, he touches a mysterious dragon-shaped pendant he received when he retired. A warm current flows through his body, unexpectedly opening the path to cultivation: a vortex of energy gathers in his dantian, his hidden injuries quietly heal, and sealed powers and the secrets of another world awaken.
When Zhang Hao makes a grand proposal at a class reunion, when the Lin family treats Lin Chen as a discarded pawn, and when hidden forces of cultivation and dark shadows begin to surface in the city, the battle-hardened king of soldiers can no longer remain silent. Drawing on the iron will forged during his military career and his newly awakened power of cultivation, Lin Chen gradually breaks through every impasse: delivering face-slapping blows to his arrogant rival, exposing the Lin family's hidden schemes, and sweeping aside obstacles with thunderous force amid the city's concrete and steel. He also carves a path through the undercurrents of the cultivation world.
He must not only rise to the top and protect those he cares about, but also uncover the secret behind the pendant and reveal the truth about the mission from years ago. From a live-in son-in-law who endured contempt to a formidable cultivator who commands the city, Lin Chen proves with his fists and strength: the dragon lies hidden in the depths, waiting only for the moment to soar into the sky!
