Han was entirely focused on elevating his path to the level of an incomplete law, but the problem was that he was failing. He had no idea how to achieve this, nor had he found anyone who had done it before. This idea had been a recommendation from his master. To make matters worse, he was nearing the end of his lifespan, having used far too many treasures to stay alive in other realms.
He only had a few tens of thousands of years left at best, but that wasn't a good thing. All signs pointed to his impending failure. His massacres were the only thing that helped him, but unfortunately, it wasn't something he could practice often. At that moment, Han's strength placed him as the strongest mage in the world. He was perfectly capable of killing billions and walking away unpunished. However, the problem was the old man who protected this world; he was much stronger than Han.
