My Sister, the Platinum Killer

One day, two people came to compete in the finals of the Killer Professional League. "Hello everyone, what is the highest level you have reached as a killer?" "I, the ninth-level killer, will be arbitrary for eternity. Everyone in the world is an ant, including you!" Lin Feng, who was in his early twenties, shook his head slightly and remained silent. "Well, what is your greatest achievement?" "I once sneaked into the palace alone, cut off a hair of the emperor in front of thousands of soldiers, and escaped with my body intact!" In response, the emperor sat at the top and frowned. But Lin Feng remained silent. "You didn't do this, you didn't do that. How did you get to the finals and dare to compete with me for the championship?" Lin Feng, who had been silent for a long time, smiled crookedly, "Because of my sister, the platinum killer!"
