Mystery Descends: My Exchanges Are Not Equal

[The 3000th Descent of Mystery is about to begin.]

[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.

[Exchange successfully. You used half a bowl of cup noodles. With your Rank SSS talent, you may retrieve an unlimited supply of cup noodles.]

[Exchange successfully. You used a bottle of Sad Breeze wine to exchange for the Star Shifting Method.]

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