Tiandu Emperor chuckled, "Kid, are you confused? You want them, but what are you offering now?"
Yang Chen then remembered the key. The Tiandu Emperor didn't know that he possessed the second key, and it wasn't possible for him to break the rules just because he treated Yang Chen differently. In fact, the current Tiandu Emperor was just a soul, and the rules he set during his lifetime were not to be broken.
Thinking of this, Yang Chen didn't conceal anything anymore: "Senior, this junior still has one more key!"
With that, Yang Chen took out the second key.
