Lu Yan was once an ordinary accountant in the Great Zhou Dynasty. His life really began only when his memories of his previous life were awakened and he was bound to the "Tianjiao Cultivation System" for saving the orphan Qingxuan. Qingxuan, the little girl he regarded as his own sister, became the softest concern in his heart. In the eyes of outsiders, Lu Yan is ordinary and gentle, and his greatest ability seems to be to take care of his sister in every possible way. However, when Qingxuan showed her peerless talent and took steps towards the road of being a strong man... When she was just beginning to learn writing, Lu Yan became enlightened. When she was powerful, Lu Yan became a saint in the flesh. Everyone in the world said that Lu Qingxuan was the daughter of destiny. But they didn't know that her brother Lu Yan had already cultivated invincible magical powers in the warm daily life of "teaching" his sister, between laughter, anger and scolding. "My sister, the cutest in the world, should also be the most powerful in the world!" As for those who want to take advantage of his sister? Lu Yan smiled kindly: "Perhaps, you have some misunderstandings about ordinary."
