True Monarch Yellow Mountain's safety seal

"..." Song Shuhang. 

F*ck, you stupid whale, what are you doing? You actually dared to swallow this stuff that came from who knows where? Are you not afraid of getting sick from eating something bad?

He was planning on using it for practicing 'soul-ferrying'—Song Shuhang was thinking that if he used the soul-ferrying technique on the blood demon core and the Blood Shrine, his power of virtue would increase once more, causing more changes to the virtuous lamia.

The lamia had become increasingly interesting, and Song Shuhang was now very much looking forward to the next changes that would happen to her.

Well, that was that. The whale core had opened his mouth and swallowed the ball, and the Soul Ferrying Technique ended without being able to finish.

After the fat whale golden core swallowed the blood-red ball, it calmly descended to Song Shuhang's side, swimming around gently.
