Time-Space Capsule (3)

Ye Kai was about to open the door, but he felt a strange energy in Ye Ming's room. He frowned as he felt this energy was familiar but at the same time not.

[Host, this is lesser spiritual energy. In simple words, this is spiritual energy but at a low level. Your sister is trying to breakthrough Martial Arts Elder. It's better if you don't go right now]

"What do you mean lesser spiritual energy? Does spiritual energy also have levels?" Ye Kai frowned and asked.

At his question, the system explained.

This world has Martial Art Students to Martial Art Emperor realm, a total of fifteen realms. However, this realm was only for islands where was not a single trace of spiritual energy could be found.

Otherwise, the island where spiritual energy could be found didn't have Martial Art Students to Emperor Realms. They had a Body Refinement Stage 1 to Stage 9.
