Zhao Hai immediately realized that there was no emotion in the world that could not be used to kill. It only depended on where you used it and whether you used it well. As long as you used it well, even such a happy emotion could be used to kill. If you used it badly, even a desperate emotion would not be of much help.
With a single thought, Zhao Hai's desolation had already attached itself to his saber. He then launched another attack, filling the entire world with despair.
The old cultivator thought that he would be able to take care of Zhao Hai easily with an emotional attack. However, he soon realized that it wasn't the case. Zhao Hai could also use an emotional attack, and it was a stronger one among emotional attacks. Although any emotion could be used to attack, the emotion of despair was indeed more advantageous than the emotion of happiness.
