Hour Glass Tower!

Elias woke up with a migraine and he found a single stalk of grass resisting the two winds. The refreshing energy yesterday was but had activated his mental faculties.

He shook his head and looked around, then he began building large slabs 1m tall and 2m thick with the best possible combinations.

It's the strongest and the hardest slab he ever made. He worked his body to the bones before he sat panting while also figuring out the next best thing.

He ate and he continued making the slabs. After his side was filled with them he began arranging around the edge of the Island.

With Wand's efficiency in just three days, he raised another wall while he was at the centre. 

The beast returned but he sent it back with explosive spears made of Wure Liquid and Metal Dust. With the explosion, the entire way was engulfed in fire and it was enforced by the East wind.
