From MC's Perspective:
Inside the basement, the old man Transmutation Wizard is smiling ear to ear. The next second, he took a few more dead bodies out from the storage bracelet and then dropped them on the ground.
These corpses were fresh and new. Their mana cores were intact. He brought them here to eat the mana core.
Next, he raised his hand.
A parasitic mouth comes out from the high right palm. The parasitic mouth extends long before piercing into one of the bodies before coming into contact with the mana core.
Munch!
The munching sound can be heard. The old man's eyes flickered. He is getting feedback from the parasitic organs. He feels rejuvenated.
On the other hand, I'm watching the whole scene from the Gregor Mansion. Thanks to the Gregor Mansion, I can hide and observe external things without any fear.
"Damn," I muttered while observing the gore scene.
