The Zhou Dynasty was prosperous on the surface, but in reality it had strict classes, serious strife in the back houses, and the existence of the law of cause and effect and weak metaphysical power. Lin An, a modern senior psychological counselor with a calm and delicate personality, fell to his death accidentally and unlocked the [Happy Life] system. It does not provide crude "full-level cultivation" or "magic weapons", but "life skills", "emotional comfort", "basic medical care" and "crisis warning". Ensure that the host (baby) lives up to 80 years old (ancient version of time measurement) in a "healthy and happy" state. Note: If the host dies young or is depressed for a long time, Lin An's soul will be erased.
