Venganza's body trembled as he performed his Second Ignition. Now that the Concept of Sloth modified his liver, immense amounts of vitality and energy would gather in his blood whenever he was out of a fight, which he could use to enhance his battle power for a short time exponentially.
The enhancement in physical might the first Astral Black Hole could not improve his body, which was already as strong as that of a Rank 8 life form, but the second made Vengaza feel his flesh and blood improving.
Neo-Demons need several weeks, if not months, to get used to that improvement and let the Astral Origin achieve a balance. Nevertheless, Venganza was different. Thanks to his constantly mutating Depravita's physiology, he did not need to rest after performing an ignition.
