"Secret Exchange?"
The Nightmare Fiend Emperor and the Jade Dragonling were pleasantly surprised when they heard Ajax's words and looked forward to seeing what he was planning to sell this time.
Previously, Ajax had taken out Smaller World Cores and Normal World Cores and at that time, he made a contract not to divulge the information about the items or the supplier to anyone.
Of course, in the case of Jade Dragonling, he could tell his parents.
And now, Ajax had mentioned the same lines which means he was taking out some similar to the World Cores or even better since they had just signed the NDA of the Trader's Realm.
"Since Sir Nightmare Fiend Emperor is a Dark-type Bestial Cultivator, I have something you might feel useful."
'Swoosh'
Once Ajax took care of his precautions, Ajax took out a Giant Dark Crystal and gave it to the Nightmare Fiend Emperor.
