Within the hidden chamber.
Colorful balls of light kept floating out of Lu Sheng's body.
These balls of light were like soap bubbles. Their surface shone with different scenes which showed Lu Sheng's experiences across the different worlds. The essence of the worlds which Lu Sheng obtained were these balls of light of different sizes.
'My radiant disc's foundation is power. So, some of the cores should be built around power. I'll use the other essences as fuel and leave only the parts of pure power.'
With Lu Sheng's thought, the balls of light before him immediately shrunk and changed colors. The colorful lights dimmed, and eventually shone with a monotonous gray.
Lu Sheng opened his mouth and sucked the gray balls of light. The flew into Lu Sheng's mouth without making a sound.
He could clearly feel his physical and main body's strength increase rapidly. In no time, the final ball of light vanished within his mouth.
