Ma Wuji, the former young master of Fengyun Hall, suffers the annihilation of his entire family. Burdened with a blood feud but lacking even the strength to kill a chicken, he finds himself in a desperate situation. He binds himself to the “World's Number One Begging System,” and his only path to becoming stronger turns out to be begging on the streets. From kowtowing and pretending to be dead to playing the erhu and using disguise techniques, each skill is stranger than the last. He leads the elderly, weak, sick, and disabled members of a third-rate gang into a martial arts tournament, making a stunning comeback with the Beggars' Sect's secret techniques. Eventually, he faces Long Chaoxiong, the enemy responsible for his family's destruction, in the arena. Once his accumulated begging money reaches the required amount, the system's ultimate martial arts technique unlocks—and the ultimate showdown that spans a blood feud truly begins.
