It was a tiny streak of spiritual essence, not much different from ordinary spiritual essence. That was why Himmel Soan hadn't noticed it until now.
That spiritual essence changed slightly when the tunnel closed. If he hadn't been examining himself, he would have overlooked the abnormality again.
Although he had found it, he didn't know what to do with it.
"Should I destroy it? Will there be repercussions?"
He couldn't say for sure. At least nothing had happened so far. He didn't know about the future. He was worried that the spiritual essence would run wild inside him.
"Firey, can you sense the streak of spiritual essence in me?" Himmel Soan asked.
"Yes, I can. Do you mean that black worm? It's so disgusting! Want me to get rid of it?" said Firey.
She had been in a deep sleep recently.
Having switched back to her original form, she didn't have much to do. Therefore, she slept soundly and was woken up just now by Himmel Soan.
