“You're saying this antidote only exists in the main world, right?”
Zheng-Fu's eyes immediately lit up as he consciously and carefully analyzed the elder's words once again. Although he was impatient and wanted to find a way to save Fu-Er as quickly as possible, he did not lose his sanity to the point of not listening to the reasons of others. So, when the elder said that, Zheng-Fu figured it out.
“That's right, kid! You've heard what Monster Kid Duan-Xi-Gong said: Ancient Winter Captivity Heavenly Poison was unearthed in one ancient ruins long ago, and no one could invent its antidote. Even though I don't know how this poison came into this world, I know that it's just medium-stage medicine for the main world, not worth anything.”
The elder briefly explained to Zheng-Fu the priorities of this poison in the main world. This meant that the antidote could be found without having to take any risks.
