Young Aguang has a touch of red cinnabar in his heart

Aguang said, "Sister Beauty, I will come to ferry you."
The young man died in a foreign country before he could be crowned. Aguang held the beating heart in front of her with all his strength, "Sister Beauty, don't commit murder again. If there is an afterlife, I'd better not meet you again."
Once she succeeded, all her bones were withered, but by the time she got the most exquisite, most fervent, and only true heart in the world, the young man had already drifted away, taking her place and falling into the abyss forever.
