"Civilization Furnace": A unique method of E-level civilization that all players within the civilization can use.
There are various ways to use it, as follows.
One, combine all the props, Star Coins, experience, skills, etc. in your backpack into a single attack, unleashing an extremely powerful strike. Items that are fused will shatter, Star Coins will be consumed, skills will be erased, and experience will reset to zero.
This strike is called "Self-Destructive Strike."
It packs a tremendous punch; a level 20 Supernatural being can easily kill a Supernatural being of level 40, who is several times stronger, using this skill.
The power of this strike depends on the Prop Level you have and the amount of Star Coins amongst other factors.
