In 2152 AD, the last human spacecraft tore through the sky and abandoned the "unqualified" Xie Xiaotian in the wasteland. Holding a wooden sword engraved with "The sword is here, the sky is here", he became the last human being on earth. When the veins begin to breathe, the crystal sword in the deep sea wakes up, and the giant ape in Penglai Reef wakes up from its kitchen dream - the seven keys that connect civilization and the planet appear one by one. The seven abandoned "flawed products" will use swords and fire to carve a way home for this dying planet.
