The Real Storm Pill

The young girl gave a humph. She continued attacking, but said, "The pill formula for this Storm Pill was a damaged, incomplete one. My Master spent a considerable number of years and finally managed to complete the formula. Such a feat was an incredible contribution to the field of alchemy and you dare to insult my Master, so don't you think you deserve a beating?"

Eh, the Storm Pill too was lost in the passage of time?

Ling Han could not help frowning. What was going on here? Why had so many pill formulae from his time been lost? Reverse Pill, Storm Pill... Dark Moon Grass actually being used to concoct Purple Origin Pill, which was a spine-chillingly wasteful use of the Dark Moon Grass...

Logically, after ten thousand years, even if knowledge of alchemy had not improved much, it shouldn't have degraded to such a level, right?
