In truth, he didn't have much confidence in his heart.
He was currently only at the Eighth Tribulation.
The gap was too vast; trying to achieve the combat power of universe at the Eighth Tribulation was incredibly difficult, let alone reaching the level of a three-star Universe God.
Currently, the only thing he could improve upon at the Eighth Tribulation was his Origin Source, increasing it to the extent of enduring Tribulation, roughly tripling it.
That meant three miniature spacetime rivers.
With the increase in Origin Source power, his Starry Sky Chronicless and the fifth sword move might be able to kill a weaker Universe God.
But this was far from sufficient.
He had to become the Ninth Tribulation!
Upon reaching the Ninth Tribulation, his fundamental divine power would first surge dramatically.
He could also venture into the Starry Sky Secret Realm to obtain some treasures.
