Dead Men Tell No Tales

Ghosts have a reason to exist. They would cling to that last string and remain in this world. Be it an old grudge or the smallest of unresolved conflicts, it was enough for them to stay. Some of them were special: some even stayed for love.
He Xuan didn't fall within either category. He didn't exist for a love so great it could burn the heavens and topple worlds, nor were his unresolved conflicts anywhere near small and his grudges old. Oh, but He Xuan was indeed a special individual. In fact, his hatred, though it had been accompanying him for a long time, still burned as vividly as ever, and, when set free, his rage could very well destroy everything in its wake, swallow it all like ships in a stormy sea.
