Bab 1167: Green With Jealousy.

But death is not his greatest fear. His greatest fear is death without a purpose. Legion hates wastage. They hate making losses. To have his entire life be a waste is not something he is looking forward to. 

Helios had to step in. "No one is dying okay? It is just a short experiment. It won't last more than 2 seconds. Maybe less. I just want to see how Chaos energy reacts with the law fragments of order in my body. I will be slightly injured at most. It shouldn't affect you and Legion-8 at all."

"Fine. Just get it over with." Legion-5 said.

The tree father prepared with Aeternus and Helios. Then Chaos energy went from Aeternus to Legion-1 and from Legion-1 to Helios. The rest is history. 

When Legion-5 came to, a black orb was revolving around his egg. It passed through the incubator as if it were an intangible phantom. No one could see it either. Only Legion-5 could see it but he couldn't control it.
