My Sister Is Missing, I Will Kill All the People in the World

Ling Yun was reincarnated into a world of high martial arts where thousands of races abounded and the strong was king. He and his sister depended on each other for life, and they were called sister-controllers. It took ten years to establish the Lingtian Group, get involved in countless industries, absorb huge amounts of funds, develop various technologies, learn many secrets, and become the richest man in the world. On this day, Ling Long, the most dazzling martial artist in Blue Star, mysteriously disappeared in the Tianyuan Life Restricted Area and was accused of betraying the human race. The martial arts alliance put pressure on the two brothers and sisters, and the major families joined forces to seize the Lingtian Group. The public was outraged and insults followed one after another. Ling Yun, who had activated the sign-in system long ago and became a peerless master, mastered many secret techniques and martial arts, so naturally he could not just sit idly by. Devil Fruit, Zanpakuto, Blood Succession Limit, Naruto Jutsu, Zhan Fist Walking Demon, Three Color Haki, Demon Slayer Breathing Technique, Taiga Sword Intention, Immortal Magic Secret Technique, Immortal Cultivation Magical Art... Faced with the unabashed conspiracy, Ling Yun simply stopped pretending and suppressed the entire era as a martial saint. "If my sister makes any mistake, I will kill all the people in the world!"
