Chang Wei is a third-rate little welder who earns a living on the construction site. When he was boiling mutton, the electric wire leaked, and he was sent to the world of steel and became the young master of the Chang family. During the family crisis, Chang Wei awakened his welding skills and helped the family overcome difficulties and obtained steel. No one in the world can practice the ridiculous exercise 'Great King Kong Jue', but he doesn't know that it is tailor-made for him, and he has stepped on the road to the top.
