The energy reached its peak and Nero begin to move; he is being very careful and moving slowly, melding with thick energy perfectly.
His method is so good that even a Sovereign standing beside him won't be able to discover him. Though it will only happen in thick energy, like this; other times it is hard.
Only Nero could do something like this. The energy, is so dangerous, that even Peak Sovereign wouldn't want to be in it.
Some of them would be able to bear it; it would be uncomfortable or even painful to them.
So, it could be said, his only challenge is to escape from the soul sense of the Earth Sovereign. Who wouldn't be searching for the Initial Sovereign monster, but if it found Nero, then no matter how amazing his ability is, he will not escape.
A few minutes passed, and Nero had crossed quite a distance.
