Cao Feng immediately placed his hand on Hua Mi's palm and pulled her along.
"~~Back~~~" He shuddered violently, as if struck by lightning, "~Back~"
~Cao Feng~~zizizi~~[eye roll][eye roll]~~
Cao Feng, who was already exhausted, suddenly felt full of energy. He pulled Hua Mi back quickly, and without thinking, he turned around and charged into the mud pile with great vigor.
Hua Mi looked down at her palm; the energy ball in her palm had been absorbed by Cao Feng with a slap.
Seeing Cao Feng so energetic, as if he had taken some kind of stimulant, tumbling and rolling around in the mud, Hua Mi suddenly understood.
It turns out that the nature of this energy cluster is just like the crystal core from a past life.
Crystal cores are crystals extracted from the bodies of zombies and mutated plants and animals, containing abundant energy.
Those with superpowers need to replenish their superpower energy using crystal cores.
However, it doesn't exist now; the crystal nucleus will only appear when there are major mutations in plants and animals.
Because the energy within the crystal core is so violent, ordinary people cannot absorb or use it. In the hands of ordinary people, the crystal core is just an ordinary crystal.
Therefore, later survivors also used crystal cores as currency.
Eventually, crystal cores became the common currency among the survivors.
Hua Mi took out another energy orb from her level 13 storage.
In just a short while, her level 13 storage had been filled with over a thousand energy orbs.
This energy cluster appears to be usable by ordinary people.
