You Haven't Graduated Yet, but You, the Last Person in the World, Have Become the God of War.

Ten years ago, a sudden disaster swept the world and the population dropped sharply. Cracks appeared in the void around the world, and countless monsters came in. Monsters are distributed in the ocean and land, and begin to invade human cities unscrupulously. Ten years later, genetic warriors spread all over the world, struggling to resist the invasion of monsters. Lu Chen traveled through time and became a student at the end of the crane. He activated the "God of War" system and was rewarded for killing non-human creatures. Thus, Lu Chen began a different path to becoming stronger. "Ding! Kill a mosquito, punch strength +0.01 Kg." "Ding! Kill ten flies, speed +0.1M/s." "Ding! Spray to death a group of cockroaches, punch power +1 kilogram." "Ding! Kill a monster, punch strength +100 kilograms, speed +10m/s, brain width +..." When they graduated, all the students in the martial arts school were shocked! "What the hell? We haven't even graduated yet, and you, the one behind the wheel, have become the God of War?"
