Lin Xiaoman, a 26-year-old unemployed copywriter, has only 7.2 yuan left on his bank card, and his rent is about to expire. On his birthday, he picks up a talking fat orange cat and accidentally gets a copper bell that can summon cute pet immortals. He originally wanted to rely on the immortals to turn his life around, but the ones he summoned were always sign spirits with "off-track" abilities. On a blind date, he meets the God of Wealth turtle; when writing advertisements, he meets a rhyming parrot. The immortals cannot solve his practical problems for him, so he can only make his own choices and bear the consequences. Until Heifuxie appears, the old accounts and mysterious black bell left behind by his missing father gradually surface—every crookedly drawn sign actually points to a hidden truth.
