In Douluo Continent, I started by obtaining the Supreme Bone of Double Pupils.

In the vast expanse of the Douluo Continent, Yang Yuan's life took an extraordinary turn when he transmigrated from his world. Initially, he was bestowed with the Perfect World Supreme Transcendence System, a powerful tool that promised unparalleled growth and abilities. However, in a shocking twist, the system realized it had mistakenly bound itself to Yang Yuan and promptly abandoned him. Before its departure, the system left Yang Yuan with a parting gift - the Supreme Bone of Double Pupils. This rare and coveted treasure is said to signify the invincible path, with the presence of double pupils and multiple bones unlocking numerous martial soul possibilities. With his newfound twin martial souls, Yang Yuan embarked on a triumphant journey, ascending to unprecedented heights with ease and finesse, his abilities allowing him to effortlessly dominate his surroundings, covering the sky with a mere flick of his finger.
