Douluo: I’m a Biology Scholar, and I Awaken a Tool Spirit?

A One Piece side story with more than ten thousand paid subscribers.

In his past life, Chen Feng was a biologist. After transmigrating to the Douluo Continent, he originally hoped to awaken a biology-type martial soul to make research easier, but instead awakened a weapon martial soul: the Taiji Eight Trigrams Sword.

The yang sword governs life, the yin sword governs death.

However, the martial soul is damaged, and only three trigrams remain of the Eight Trigrams.

In order to freely study soul masters and soul beasts, Chen Feng sets off on a journey to repair his martial soul and become stronger.
