Cheng Haotian is the twenty-fourth generation head of the Cheng family of the ancient demon clan. He faked his death and escaped five years ago. He guarded the stone walls, sheepfolds and earth veins in Jackdaw Ridge, trying to live a stable life. Wang Ziyi is the legitimate daughter of the Wang clan of the immortal clan. She was proposed to marry by another immortal clan of the Nan clan, but she found a sealed ancient book in the library - The Origin of Immortals and Demons. Two enemies who were supposed to be sworn enemies met at the altar of Mount Sumeru and repaired the seal side by side, from one person to six people. The gate of heaven is sealed, the earth network is connected, the three realms are connected, and the trade routes are stable. Cheng Yuanshan sat at the border of heaven for forty years, but the person he waited for never came. Cheng Cang had been guarding the northern front for thirty years, but the people he waited for never came. But Cheng Haotian and Wang Ziyi don't have to wait. They can stay. There are two broken swords on the stone wall, there are twelve sheep in the sheepfold, and the date trees are bearing fruit. The journey is over, but the days are still going on.
