Back on my Side!

When Shadow had grown to a hundred kilometers in length, the Devil informed Nial that he was ready to teleport him through the Meteorfield.

Shadow was still at the Mythician rank but he was advancing rapidly. Beasts were faster at advancing in their rank during their growth phase. Their progress would only slow down upon reaching maturity. 

Nial was not sure when exactly Shadow would reach maturity because the Devil was already extremely long and huge in width and height, but the most important was that Shadow could bring him back to the other side of the Universe, in the first place.

That's what interested him most.

Nial had to make sure that he finished his research in the unknown part of the Universe. After all, it would be a hassle if he left some open ends which he had to re-research just because he was rushing things too much. Nial finished his research on the hieroglyphs and he tried to recreate them with his acquired knowledge.
