One Bihai Pill can greatly increase internal energy when eaten, and one Moon Watching Pill. It is said that if a woman eats it, she can be reborn and become astonishingly beautiful. Countless people wanted to ask the owner to show off the true appearance of the magical pill, but they were all rejected by the owner.

That day, the blood all over my body was boiling. Amidst the flash of swords and shadows, I could no longer tell whether I was still alive in this chaotic world... (Ending HE)
