This vengeful spirit alone provided Song Jian with a full 4.3% of battle experience, which was much higher than the Demon Bone Monks he had encountered before. If converted into a specific number, it would amount to at least several hundred thousand Experience Points.
Moreover, the other Demon Bone Monks also provided Song Jian with 1%-2% of battle experience. After the fight, Song Jian's Experience Points had increased by more than 10%.
Among the spoils of battle, what surprised Song Jian the most was a Purple Crystal dropped by the vengeful spirit. The rest were high-level alchemical materials that fell into the category of alchemical biology.
Song Jian could only sell these materials, as he had some knowledge in alchemical pharmacology but was completely clueless about alchemical biology.
After sorting out the spoils, Song Jian walked toward Master Yiwen.
