I Contracted Myself

Story:

This is a world where awakened people and alienated beasts coexist. Zhang Ping was lucky to become an awakened person, but his ability was rated as useless. He was unwilling to live a mediocre life, so he resolutely swallowed the contract gem that ordinary people avoided like snakes and scorpions, contracted himself, and became his own summoned beast! From then on, the whole world opened up to him. Ever-changing superpowers, endless alienated beasts, and dangerous parallel worlds, everything is possible.
