"Reborn as a Snail, I Build a Base in the End of the World": An ordinary young man is reborn on the eve of the end of the world, but sadly turns into a snail. But he discovered that he could control metal and command insects, so he used the snail's concealment to quietly build a huge base under the ruins of the city. He commanded an army of ants to transport supplies, spiders to weave webs for early warning, and snail slime to transform weapons. He attracted a group of human survivors to follow him and became the most mysterious and powerful "Snail Lord" in the apocalypse, leading everyone to counterattack and survive.
