Kingdom of Light: My Trading Agent, Creditor in the Universe

Lin Luo was originally a person from the normal world, and Ultraman was just a special shot on TV. But suddenly one day, Golzan, who should exist on TV, appeared in reality and destroyed the entire world. Out of desperation, trading systems emerge. The system gives Lin Luo the ability to save the world, but the price is that Lin Luo becomes a slave of the system, helping him collect valuable things until the debt is paid off! Ever since, a multi-dimensional exchange appeared in the entire multi-dimensional Ultra Universe. "The invincible first generation was defeated by Jayton? It's okay. Give me a thousand years of fighting potential, and I guarantee you a lot of it!" "What? Dagu, you were still a little panicked when you beat Gatanjie. It's okay. Sell me the Dark Tiga in your hand, and I'll guarantee you to pierce the conch on the spot!" "Beria, are you a little annoyed that you can't beat Cero? It's okay. Sell me the entire Galaxy Empire and I promise you will always be stronger than Cero!" … The entire universe, not only Ultraman, but also the people in the universe, will make deals with Lin Luo. Unknowingly, Lin Luo has become the biggest creditor in the entire Ultra Universe!
