He Xiaoyao, the Dragon Lord of the Eternal Ages, once stood alone amid the mountains and seas of dying flame for a thousand years, guarding the abyss and slaughtering countless spirits. Now he sells chili peppers at a stall in Linjiang's vegetable market, wears mismatched socks, charges twenty yuan to repair a rice cooker, and considers lying flat his greatest ambition.
The Abyss Guard asks him to fight monsters, but he ignores eighteen calls. When a branch office is hit by a supernatural disaster, he says, "Send someone yourselves." Then the orthodox female immortal Wen Ciyue descends with her sword and says, "There is a Dragon Lord in Linjiang. He must know what lies beneath the abyss." She hauls him up from his folding bed.
He thought it would be a matter of fighting monsters and leveling up, but the deeper he investigates, the more he uncovers:
The Classic of Mountains and Seas is no myth. It is a true account of the martyrs of ancient times.
The so-called "supernatural disasters" are the myriad spirits who protected the world, slandered by the Heavenly Dao. The guardians of the abyss throughout the ages never killed demons. They killed loyal defenders who had shielded humanity from annihilation.
Wen Ciyue had obeyed the rules all her life. That is, until she turned them over and saw that every page said, "Fill the holes with your life."
He Xiaoyao hands her a cup of unsweetened soy milk. "If you sacrifice yourself for the Dao, the Heavenly Dao will just turn around and use you as firewood."
He rebels against fate; she breaks the laws of heaven.
He once sought freedom for himself. In the end, he won humanity a world where people could live freely.
She once guarded the moonlight through the ages. In the end, she kept a night lamp burning for him.
One wild and one upright, one carefree and one serene, together they guard the eternal, uncanny abyss.
But their true enemy has never been the myriad spirits beneath the abyss. It is the Heavenly Dao itself, which feeds the cycle of reincarnation with the flesh and blood of those who sacrifice themselves.
