You Brought up the Breakup. Why Are You Crying When I Refine the Human Emperor Banner?

This is a world of high martial arts where aliens invade, the strong are respected, and the weak have no human rights. The time traveler Lu Chuan has obtained the inner demon system. As long as he harvests other people's fears, regrets and other emotions and makes them breed inner demons, he can add points to improve his cultivation and redeem them for treasures. From then on, in order to become stronger, he completely embarked on a road of no return. The moment the Human Emperor Banner was redeemed, he proved the way through killing, swept across the wasteland, and bloodbathed the heavens and the world. In the past three years, the gods and demons in the heavens were frightened when they heard his name, and even took in countless lonely souls and wild ghosts. … When that day came, facing countless doubts, Lu Chuan took out his Human Emperor banner and said this. "Let me review it for the last time. I am the leader of the righteous path. I am full of awe-inspiring righteousness. How can I refine an evil weapon like the Ten Thousand Soul Banner?" "What, you're asking me why this human emperor flag is emitting black smoke?" "Fool, this is clearly Hongmeng Purple Qi, so purple it turns black. If you don't believe it, go in and ask my school beauty girlfriend!"
