The bricklayer in the old town of Jiangcheng is Niu Wuwei. He was born with a tough head and a dull temper. His parents died young and he lives with his bedridden grandmother. In order to treat his grandmother's illness, he dropped out of school and went to work. He endured humiliation and heavy burdens on the construction site. His wages were deducted by the foreman and he was bullied at will by his co-workers. Even his girlfriend, because of his poverty and humbleness, turned around and fell into the arms of the rich second generation, crushing his sincerity and hope to pieces.
On the darkest day of his life, he lost his job, lost his love, received a huge demand for surgery from his grandmother, and was surrounded and beaten by the foreman's cousin, the gangster leader Dao Scar. In a desperate situation, the mysterious power sleeping in his body unexpectedly awakened, and the soft egg that he used to be able to be kneaded by others instantly transformed into a strong man with the power to break wood and an awe-inspiring aura.
