[This is your only chance to redeem yourself.]
When the whole world was in danger, Wang Teng activated a unique talent.
It was the Rank SSS talent - Inequivalent Exchange!
He was not purchasing things for free, but the exchange was not equivalent.

From then on, Wang Teng activated a new exchange system.
