Lucifer did not refuse. "I can go in, but give me one of the large crystals you are holding. Also, leave thirty of the Energy Towers and safe Energy Bombs you have on you. With this large crystal, I can upgrade your Energy Towers to top-tier goods."
"After the modification is complete, your Different Space Domain will no longer be usable for combat. It will be dedicated solely to housing this crystal, and any living beings illuminated by the light of the Energy Tower will be able to undergo physical gigantification. You need to pay attention to this—don't mess around! This has been customized according to your unique power structure; others cannot withstand it and will die."
Producing a large crystal casually, he handed it over. "Is this thing only used to upgrade the Energy Towers? Does it have any other uses?"
