Love Between Immortals and Mortals Is Deep, Mountains and Seas Are Our Betrothed

She is the only ancient god in the four realms. She is responsible for protecting the common people, and she has been without love for thousands of years. He was the prince of a mortal emperor's family, he was stubborn and unruly, but he was willing to die for her and embark on the path to immortality. In the troubled times of the underworld, the way of heaven bites back, and the divine power declines. He used his mortal body to block the disaster of the god; she used the bones of a ten thousand-year-old immortal to exchange for his peace in his life. "There are immortals across the mountains and seas, and the mountains and seas can be leveled."
