Capítulo 331: The Technique Not Easily Shared

Achieving mastery in the Slaughtering Spirit Technique not only increased its killing power but also brought about a noticeable change: the purity of the spiritual essence obtained through slaughtering became somewhat improved.

This was because the execution of the Slaughtering Spirit Technique had become more precise and delicate, allowing for the removal of impurities within the spiritual essence, such as fragments of core soul energy, before absorption.

However, having Chen Fei directly absorb these spiritual essences was still somewhat inefficient. Continuing to feed them to the Qianyuan Sword was still the better choice.

It was estimated that when the Slaughtering Spirit Technique reached the stage of perfection, further reduction of impurities would occur, and at that time, absorption might become feasible. To achieve worry-free absorption, Chen Fei would need to find complementary techniques for the Slaughtering Spirit Technique.
