Just one person was enough to completely dominate the world.
This kind of being, whose body could fully energize, had no weaknesses.
Unless his immortal body was destroyed, a True Immortal almost never died.
And their immortal bodies were so strong that they were immune to nearly all attacks on Blue Star.
Only the core power of a nuclear explosion could cause them fatal damage.
In other words, even if a True Immortal was on the periphery of a nuclear explosion, the radiation and high temperature that could bring fatal damage to human life forms couldn't harm them at all.
Moreover, even if a True Immortal manifested in a form hundreds of meters tall, they could burst forth with speeds at least ten times the speed of sound, with an attack range of over a hundred miles.
This kind of moving natural disaster...
Given enough time, they could completely destroy the entire ecosystem of Blue Star.
Exterminating human civilization was not just an empty threat.
