Tank soldier Lee Si is reborn as a young Godzilla, just in time for the countdown to the invasion of the alien beast. Feeding in the zoo made him discover that eating can gain evolutionary points. Thanks to rewards in the live broadcast room and the allocation of resources across the country, 1.4 Billion people became "feeders" to help him grow rapidly. Genetic researcher Lin Qingxue saw through his wisdom, and the country listed him as a doomsday trump card. From a giant beast in the zoo to an Alpha-level warrior guarding China, Godzilla joins hands with humans to build a line of defense against invading giant beasts such as Ghidorah. He uses his atomic breath and the power of evolution to prop up the hope of human survival. A doomsday symbiotic battle between humans and giant beasts begins!
