Critical Eidolon

Because a meteorite carrying mutated genes hit Blue Star, one-third of the creatures on Blue Star mutated into a creature called "Phantom". After research, it was discovered that the attack power of phantoms is not only stronger than any other creature in Blue Star, but humans can also form contracts with phantoms. After signing a contract with the phantom, you can obtain the "spiritual equipment" transformed by the phantom and the spiritual energy with corresponding attributes. As a result, the humans of Blue Star have received a huge technological boost. Not only can it catch up with the level of major civilizations in the interstellar world, but it also opens up exchanges between Blue Star and alien civilizations.
