Capítulo 1282: Accept The Bestowal Of Greatness.

This is the first time he is using soul force to fight directly. Origin gods use it to push and pull the law matrix. It is a more powerful means of the manipulation of laws but rarely do Origin gods use it to attack each other. Only immortals with spiritual concepts use soul force directly but those are rare.
