During the past hours they kept fighting like hell, never got the chance to rest or even take potions to heal themselves. After healing the most serious wounds, replenishing the almost depleted spirit power of many, they started to focus on strengthening the ground with lots of arrays.
Right now, the two pieces of land they secured didn't experience any deep or serious looking cracks, not to mention having pieces of the ground fall or something. But there were still many small cracks appearing from time to time. And so, they started to strengthen the ground again.
As things kept growing intense like this, no one really minded the fall of the world at this point. To them, they just wanted to get rid of all these monsters, get rid of such deadly situations once and for all.
In less than one more hour, the entire world suddenly shook like it was going to end. And with it, thick tongues of dust rose high in the air with the fall of the ground.
