Inside the Tiger God's realm, Leavemealone and the others were still fighting the hordes sent by Tiger God's other half. They were not sure how long they had been fighting, but it could probably be one day already.
Fortunately, though the number of the enemy that spawned increased, the level never went up above level 60. The rare elite grades also never reached a number where it was too overwhelming for them to deal with. Additionally, the Tiger God's Might cut down all their skills' cooldown by half, allowing them to unleash their skills more frequently.
They also magically didn't feel fatigued inside this realm despite fighting non-stop for such a long period. It was either the Tiger God's Might's hidden power or this realm's effect.
