On the way back, the two skeletons talked about the story of Chirute all the way.
In their description, this "Nether Guard shaped like a gas tank," known as the "Long Chirute," first appeared seven years after the Void disaster.
It was air-dropped like a nuclear bomb into Sky City, and with one blow, it shattered the protective barrier known as the "Wall of Despair," killing at least five hundred Totemists.
Afterward, Long Chirute became a staple on every major power's "hunting list."
Requirement: Capture alive!
The reason is simple; its self-destructive lethality was too great.
Moreover, every time Chirute self-destructed, the lethality of its self-destruction improved.
After all, this thing was considered a skill; it grew more proficient with each blast and would level up after many detonations.
Therefore, all parties wanted to acquire this spell from Chirute's body to reverse-engineer and produce large-scale weapons of mass destruction for their own use.
