Xiao Yichen, a menial disciple of the Xuantian Sect, unexpectedly awakens the Grandmaster System of Myriad Laws Returning to One. Relying on a broken broom and taking advantage of sweeping floors to observe and collect various cultivation techniques, he is a humble menial by day and quietly cultivates by fusing techniques at night. After three years of forbearance and accumulation, he unexpectedly obtains a fragment of the Emperor-grade cultivation technique, and his cultivation surges.
