The Mirage beast had actually created an illusion of a super tsunami.
Obviously, this Mirage beast had fallen into the trap and kill array without warning, and in its panic, it had suddenly burst out with much more powerful energy than usual. Although the illusion it had released was not as terrifying as the one created by the dying Mirage beast at the cost of its own energy, the momentum was still very frightening.
Fortunately, Xia ruofei had already killed more than 20 intermediate - Level Mirage beasts on the third floor of the trial Pagoda. He had gained a lot of experience in dealing with illusions.
Hence, after a brief moment of shock and disbelief, Xia ruofei quickly regained his senses.
