I appeared behind the lich and it turned around to face me.
Phwoom!
The magic circle released intense flames that washed across the entire corridor, and I activated [Shadow Blade] and ten blades appeared in front of me and interlocked as they acted as a shield to prevent the flames from getting to me. The flames cleared out and the lich's jaw dropped in surprise.
I knew that his flames would not be able to get through the swords because the ultimate power here is still the tower, and even though this lich is meant to be much stronger than me, he is on the fourth floor, and that means that the tower reduced its power too! The swords separated and I pointed them all at the lich.
"What is this!?" the lich cried in anger as he rose his hand towards me and hundreds of fire lances appeared in front of him, "You think your stolen power will be enough to stop me!?"
