Dust-Covered Fox Eyes

The great demon Yun Shu, who was about to ascend to immortality after surviving a heavenly tribulation, was secretly blinded. The two people he trusted most were simultaneously drawn into this vortex of conspiracy.

In a luxurious cage, he finally saw the falsehood of his close friend and severed all ties with him, never to meet again.

To survive, he went into hiding to heal his injuries.

His best senior sister, an Immortal Venerable, and his most obedient disciple, a Demon Venerable, one searched the Three Realms for medicinal herbs without regard for cost, while the other tested medicines on his own body.

All of this was just so he could recover and see them again.

From being enemies between immortals and demons to surviving heavenly tribulations together.

Yun Shu, who was somewhat slow in matters of love, finally seemed to understand Heng'er's feelings.

His feelings for his senior sister are familial, and for the Human Emperor, they are friendship.

In any case, it's a Happy Ending.
