War in Subterranean World: Might of the Twin Spirits

The [Yin Yang Twin Spirits] was a powerful skill of universal grade artifact. It was a skill that could manifest two creatures of dark and light attributes. The power of twin spirits depends on the power level of the users so if the user was weak, the power of the twin spirits was also weak.

A true manifestation of Souta's unbound power. He didn't have to fight the enemy himself. Instead, he could simply stand at the back and support the twin spirits in battling his opponents.

It was easy to say that the power of twin spirits was above Souta's base form. They were as strong as his release form without any power boost from combat arts, spells, and equipment.

Nevertheless, even without those boosts, Souta's power was still above an initial fourth-stage monster. So the might of the twin spirits was something beyond their power level.

The people from Red Matter Association would need at least one Two Shackles Realm expert to hold one of the twin spirits.
