My Janitor Mom is a Kung Fu Legend

Once a martial arts legend, Irene vanished for 18 years to honor her late husband's vow, raising her daughter as a janitor. Her daughter admired the legend yet scorned her "cowardly" mother. When old enemies return, threatening her child, Irene breaks her oath on the girl's 18th birthday. Casting off her humble disguise, she storms back into the arena as the feared "Black Widow." Crushing every foe, she pursues the mastermind behind the threats. Through fire and fury, a mother’s love bridges an 18-year rift, forging a bond stronger than any legend.
