Root of Revival
"Die? You can die if you want but only after you tell me where I can find the ingredient," Su Yang said to the old man.
"Oh, right, I nearly forgot about that matter since I was so absorbed in our exchange. The Root of Revival, an incredibly rare herb that can only be found in extremely harsh environments."
"Yes, and you claimed that you know who has it."
The old man nodded and said, "Indeed, I know who has it. However, before I tell you that, can you tell me your purpose for seeking out this treasure? I have taken a good look at the list, and almost every ingredient on the list was related to rebirth one way or another. Are you trying to resurrect the dead or something similar?"
"Resurrection?" A weird smile appeared on Su Yang's face, and he continued, "There's no such thing as resurrecting the dead. Once someone passes, they will remain dead. Perhaps reincarnation may exist, but real resurrection is most definitely impossible."
