Su Xiao sat on the remains of a collapsed residence and checked the prompts from Reincarnation Paradise. They were mostly notifications about obtaining World Source.

As for the Codex Cards dropped by the Ghosts, he could not obtain them for the time being. The temperature underground was too high, and considering the heat dissipation, he would have to wait at least an hour before searching.

A fragment of a Codex Card appeared in Su Xiao's hand. It was probably the upper-left corner of the Immortal King's Codex Card. As for how to obtain the remaining parts, he had no idea for now.
Just one-tenth of the Immortal King's Codex Card could be exchanged for 300 Codex Merit.
