No System. The protagonist is Mumu, a modern girl who goes exploring on Mount Emei, only to lose her footing and fall off a cliff. She arrives in the world of Mysterious Lotus Casebook as an abandoned baby, then is taken in by the Mu family, the greatest clan under heaven. Mumu is mischievous and clever from a young age, with exceptional insight, but she has no interest in martial arts manuals and dreams only of roaming the martial world. At five, she sneaks out of the Mu estate. Along the way, she meets the three protagonists: Li Lianhua, a man with eight hundred tricks up his sleeve; Di Feisheng, imposing and haughty; and Fang Duobing, a newcomer to the martial world. The adorable little dumpling wins them all over, and the three dote on her. Li Lianhua wants to leave Fang Duobing by the roadside, but one “Big Brother” from Mumu and his heart melts. At Lotus Manor, Fang Duobing wants to knock Di Feisheng into the pond, but one “Big Brother” from Mumu and his heart melts. When Di Feisheng regains his strength and is about to kill Fang Duobing, Mumu says “Big Brother” once, and Di Feisheng stops, saying, “Mumu, we were only playing around.” When Shan Gudao gets the Mother Gu and plans to unite the world, Jiao Liqiao snatches it away, saying, “My Mumu wants it.” At a single word from Mumu, the whole world trembles.
Nice!!!
