Is the Debuff Too Much? It Doesn't Matter

[System + Decisive Killing + All IQs Online] Everyone will experience the trough of life. This book was actually written by the author himself for his own entertainment, but I still hope that everyone can see themselves in daydreams, so there is no need to distinguish between brainless and brainless! In short, just put your mind here and I will change it as you say. Just be happy! Text: After time travel, Gu Nanxing was inexplicably massacred by a killer when he was 16 years old. Seeing his parents die in front of him, not only was he helpless, but he himself could not escape death in the end... He was a genius in his previous life, but was framed and turned into a social beast overnight. Both his parents were seriously ill and admitted to the ICU. At the age of 24, he was hit by a car because of jealousy and hatred in his humble life. Not only did he hate the northwest, but his parents would die powerlessly in front of him again... As the saying goes, things can only happen in a matter of seconds. A familiar feeling came over, and Gu Nanxing found that his soul had not dissipated. At this time, the system finally awakened, and Gu Nanxing was reborn through time three times - this is a mecha sweeping across the wasteland. In a world where humans compete with spiritual beasts, the intrigues between humans also include the firepower exchanges between mechas. He was a genius in his last life. Although the curse of his third life has been eliminated, what if the debuffs are full? The mecha is really hot! In this life, even if the debuffs are stacked! Also turn on the mecha!
