One Piece: The Soul Purchasing Pirate - Chapter 300: Losing the Little Master, again!!!

The following were the talents of other cultivators: Divine Spiritual Root, Unique Body, Double Eyes, Divine Bones.

This was the talent of Chen Jingzhai: Bug Abuse.

Chen Jingzhai did not have any unique talent until he found out he could abuse bugs.

When he encountered a new martial art, he could instantly see the pros and cons and the weakness of the art.

When he fought, he could notice his opponent’s weakness and use that to his advantage.

When he brewed pills, he could abuse a special bug that allowed him to mass-produce high-quality pills.

Not only he could discover bugs while cultivating, but also in some special circumstances.

With the help of his new power, he began on a one-of-a-kind cultivation journey where he would become a legend.

On the Great Land of China, forces clashed for the sake of supremacy and Bloodline Warriors ran amok; the conflict of the strong threatened to shatter heaven and earth. A young man named Lu Li—nothing more than a humble Coffin Carrier from the Northern Desert—came along with Lu Ling, his sister. The two were regarded as puny insects and bullied, but little did people know that Lu Li had the strongest Bloodline of them all in him.

He mounted the most handsome of horses and drank the strongest of wines;

He bedded the most beautiful of ladies and murdered the most hated of people;

He told a huge lie and carried with him an ill-reputation undeserved;

He traveled all by his lonesome and danced with devils;

He had given his word that he would come back, that he would be strong.

And it was because of this that she was still waiting in the city—alone.
