Urban Gaowu: Kill Ants and Become Stronger

Fifty years ago, the sky cracked, strange beasts swept across the world, and humans retreated to seven cities to survive. Lu Yi, the last in the Lingwu class, awakened the zero-level waste spirit root and was ridiculed and trampled by the whole class, but accidentally activated the only infinite superposition system! Kill an ant and your attack power will be permanently +1! If you are bitten by a mosquito, your defense will be permanently +0.1! You can stack up defenses like crazy when soaked in sewage, frightened, having nightmares, or even being smoked by your own fart! Others have broken through the realm after ten years of hard training. He squatted in the sewers to crush ants, stood on the city wall to endure the strong wind, and buried ruins for seven days without starvation. His attributes soared without limit! Black iron? Bronze? Silver? All realms are like ants in the face of infinite superposition! S-class alien beasts attacking the city? Kill instantly with one punch! The strange true body is destroyed? Frontal crush! The whole world was shocked, and the seven cities knelt down to worship, but he turned around and went back into the sewer: "Don't bother me. I can squat for another hundred years and continue to fight ants." Infinite stacking, no bottlenecks. There is no enemy in this world that cannot be defeated with one punch. If there is, then add another 100 million points of attributes!
