As a time traveler who travels through parallel universes, the protagonist is quite lucky to have something.
Fortunately, the person who traveled through the parallel universe happened to be myself and not someone else.
Originally, the protagonist was still congratulating himself on escaping a disaster, but he always had to pay back what was due...
The stars in this world have special powers that can evolve the genes of organic creatures, and at the same time enable inorganic creatures to possess and gain the power to transform into human form.
This power is called star power by the humans in this world, and the humanoid and non-humanoid creatures with the star power crystal [star core] in their bodies are called [star spirits] and [star beasts].
However, after the protagonist awakened his natal contract spirit, the protagonist realized that something was wrong...
It seems that the natal contract spirit that I awakened is actually me!
At the same time, what surprised the protagonist was that he was actually found to be incompatible with all types of star beasts except fantasy star beasts, which means that he can basically control his own contracted spirit (himself) for the rest of his life.
Fortunately, the protagonist awakened the system in the next second.
It's just that this star beast is a bit tricky...
Hey, my own book is still a five-star rating——
