He even carried the heavy sword on his back when he slept. And when he was practicing with the heavy sword, he was extremely harsh on himself. Every single time, he had to thoroughly exhaust himself to the point where his fingers were not even able to move… At first, he thoroughly exhaust himself ten times in a single day. Then after, the number of times decreased. The Overlord’s Colossal Sword also became lighter and nimbler in his hands and the strong winds brought about by the dance of his heavy blade were even more tyrannical than before.
