He and his seriously ill mother and young sister are thrown out of the family home, receiving nothing but a dilapidated earthen house and an abandoned dry well. At the end of his rope, Li Mo unexpectedly discovers a mysterious hidden grotto beneath the well, containing a miraculous spiritual spring. Its water can strengthen the body, cure illnesses, and make crops grow at an astonishing speed. Using the premium peaches grown with the spring water, he secures a long-term supply contract with a local restaurant and gradually turns his fortunes around. Meanwhile, he uncovers the truth behind his father's supposed accidental death, eventually bringing his uncle's family to justice and securing a better life for his loved ones.
