The ORIGIN did not waste time and the first move he used was a move that could annihilate a universe.
"Heh, a big move right from the get-go!"
Leonard Tranor, one of the top ten strongest reincarnations of the Strongest Mortal Soul holding his twin blades and was able to cut through the ORIGIN's move and was able to safely negate its power.
The other reincarnations knew that Leonard or someone else would be able to negate the attack so they were busy preparing their own strongest attacks. The mages burst out with their strongest spells ones that could turn galaxies into dust, and the archers fired arrows imbued with everything they had all aimed at the ORIGIN.
The ORIGIN whose body was made of an infinite number of realities took a part of himself and shot it at the incoming arrows blocking the attacks. When the spells of the mages were about to descend, the ORIGIN was able to disrupt their spells before they were able to activate.
