Ten thousand years ago, Su Fu, the Fusang Demon Empress, sealed the boundary wall single-handedly, bringing the war between humans and demons to an end.
As her strength gave out, the Lord of Annihilation, Si You, struck her from behind, driving a wisp of “Nothingness” into her body. He did not mean to kill her. He meant to make her part of annihilation.
She chose to seal herself away, hoping ten thousand years of sleep would wear that wisp of annihilation down.
Ten thousand years later, she awoke.
Her memories were sealed, her power only half intact, and instinct was all that remained. On her first night in Lin'an's demon market, a touch of frostlight appeared on the roof.
A thousand-year-old nine-tailed snow fox, Shen Yan, guardian of the demon realm. The chill of world-cleansing and her Fusang Heavenly Fire came from the same source. He was one of her kind.
She sensed that frostlight. Every night, from the very first.
She simply said nothing.
If someone chose to watch over her from the shadows, that was his choice. If she called him out, he would have to step into the open. And once in the open, there were rules to follow.
She left a door open for him. When to push it open was up to him.
Later, she made an accord with the Demon-Suppression Bureau, rebuilt the order between the two realms, sheltered vulnerable female demons, and settled the grudges of ten thousand years past. From the depths of the Nether Capital, the Lord of Annihilation sent a voice: “I come to see you once every thousand years. Your light has never dimmed.”
She answered with heavenly fire.
In this life, she would no longer stay for anyone. But when she passed by his side, she would slow by half a beat.
She knows everything. She simply says nothing.
