Ibro hadn't heard about any admission fee from Lina before. He assumed she felt anger towards this condition, so she avoided mentioning it.
Throughout the previous battles, there were many monsters that the death knight killed. He had a lot of unused monster cores which he stored in the ruby ring.
He took out one core and gave it to those responsible for the entry fee. One cultivator who was wearing a brown outfit took it and observed the core. He said:
"Grade three monster core… that is a high-level core. Don't you have any lower monster core?"
"No, all I have is cores like this one," all the monsters Ibro killed were stage 3 monsters, so all the cores he had in his ring were like this. The man said after some thoughts:
"This core can give you some fortune inside. I will trade it with 100 grade 1 monster cores. You can pay the entry fee with them then. You are two persons, so you need to pay 2 grade 1 cores."
