The Strongest Poison

"Forget about it. I'll just explain to you the fundamentals," the purple-colored flame said, giving up hope for Yang Lujia's dull brain. "You're smart, but you're actually this dumb. How did you cultivate to this point? Never mind, never mind… anyway…"

Yang Lujia found out that the longer he had been with this flame, the more he found this flame peculiar. He was speechless at what it had just said to him just now. 

However, Yang Lujia just let him be. He was also curious. 

Could his shallow knowledge about poisons be very useless in this world?

"Poisons are like parasites that would invade someone's body. They would either slowly consume someone's vitality or directly kill them in one breath. In this world, poisons are feared by several cultivation practitioners like you. They're very detrimental to your growth. It's like a disease that would never be removed without an antidote.
