Lu Xinglao is guarding the ancestral alchemy furnace on Huangsha Planet, an abandoned planet that has been banned from the world of immortality. He lives with weeds and waste elixirs every day. His greatest wish is to refine a "serious elixir" that will not explode the furnace. Unexpectedly, one day a "fireball" fell from the sky and smashed through the roof of the alchemy house. A green-skinned creature with three eyes, talking like a bird, rolled out of it, and was carrying an "iron pipe" that could emit blue light. Since then, his peaceful and outrageous life has completely gone astray - using an alchemy furnace to block lasers, attaching heart-purifying talismans to alien spaceships, relying on poison-quenching herbs to deal with interstellar pirates, and even leading a group of strange teammates (a chatty mechanic, a road-crazy female monk, and an alien undercover who is afraid of light), staged scenes of ridiculous "anti-enemy" dramas in the interstellar space. When the ancient art of cultivating immortals collides with interstellar black technology, and when the useless alchemist is forced to take up the banner of "Guardian of the Planet", this seemingly absurd interstellar war actually hides the metaphor and warmth of the collision of civilizations. Let's see how a group of "unreliable" guys can defend their homeland and explore the sea of stars in a state of laughter and laughter.
