Troy was just about to throw his body forward to protect his hundred men, but he stopped when Ars already protected them from Temperance's destructive attack. 

With just one layer of red wall and Silver Sky Staff, Ars shielded Temperance's attack. 

It was easy because he brought the Silver Sky Staff with him. If not, he would just teleported and left Troy and the 100 spartan to receive the attack. 

After the explosive effect stopped, Ars cleared the dust on the scene by launching the red wall forward. 

The red wall opened up the area that was covered in ash. The giant black hole lead to the Lower Floor could be seen once again. 

Surprisingly, the previous explosive attack also cleared the sand from the ground around Abyss Pit. The surface of Sector 5 was actually not 100% sand.

Now that they have found the Pit on the Lower Floor. They can continue on moving forward. But before that, they need to finish their problem first.
