The Strongest Sister in Martial Arts

"System, are you saying that every time you capture an additional 'sister', you can get a random reward?" "Yes, but the premise is that the subject is determined by the system to be qualified to become the host's sister. For example, in the grass 20 meters away from the host, there is a high-quality target with a comprehensive evaluation of more than 90 points. It is recommended that the host immediately adopts the target as his sister!" Sure enough, Lin Shu saw a trembling little lolita in the grass, with a dirty face: "Hey, girl over there, sign a contract with me... And become my sister!" "If I were your sister, would you protect me?" "Of course!" "Ding! Congratulations to the host for successfully capturing my sister, and I will reward the 'Evil King' Shi Zhixuan with a personal data package!" Lin Shu received the reward and was very proud: "By the way, my sister, what is your name?" "Lin... Lin Xian'er!" Possessed by the sister control system, he travels through the world of martial arts. The first world is Xiao Li's flying knife! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
