With his wet nurse living in a border town, the wet nurse has been raising the prince quietly, and hopes that he can take on the task of restoring the country in the future. She also gave him a name that embodies the feelings of family and country: Xi Zi Tang. In the blink of an eye, Xi Zitang turned eight years old and was sent to Chuiyun Mountain by his wet nurse to practice. After practicing for ten years, he finally picked up the Martial God's Hammer left by his ancestors and broke through the martial arts realm and stepped into the fairyland. With the momentum of a newborn calf who is not afraid of tigers, he came out of the mountain and vowed to defeat the Eight Immortals, level Penglai, liberate the four continents, and restore peace to the world. Immortal cultivators are everywhere in the Four Continents. Xi Zitang is just a younger brother. After being identified by the town's Immortal List, he received the certificate of being a mortal immortal. However, in today's Tang Dynasty, even the requirements for delivering food are for being a mortal immortal. What should we do? After ten years of saving BUFF, how will Xi Zitang, who is new to the world, start a bloody storm in the world?
