After the Pet's Gene Mutated, the Whole Family Went Crazy

In the biopunk city of New Green City in the near future, rebellious high school student Zhang Xiaoqiang brought back a "luminous pet cat" briquette from the black market, claiming to be an ordinary cute pet. When the briquettes grow fluorescent tentacles and spit out strange balls of light in the middle of the night, the lives of the conservative mechanic father, warm-hearted mother and mysophobic sister are completely overturned. This mutated creature, which is actually an alien "gene sower", not only triggers a hilarious family defense battle - from using square dances to cover up to inventing disguise artifacts, but also involves the whole family in official tracing and the conspiracy of the mysterious laboratory. As Coal Ball's abilities continue to awaken, the Zhang family discovers that their bond with this "alien visitor" is far beyond imagination. This is an unexpected collision between an urban family and interstellar destiny. It is a warm science fiction comedy that explores what family and life are amid gene editing, ethical dilemmas and black humor.
