After this test, whenever Li Yan encountered sudden danger again, every instant of judgment would be critically important. He would do his utmost not to make a single mistake.
Such opportunities were not common. Outside, Li Yan could not openly attack an array or restriction of this level; that would practically be a declaration of war against the opposing force.
But the restriction here had been laid down by ancient cultivators. Whether or not he could break it this time, he would gain some basis for judging what lay ahead once they entered the city.
Li Yan would then make different plans based on this test. He also knew that the Prison-Breaking Technique he cultivated was already different from that cultivated by Tianli Clan cultivators.
That was because after refining the essence blood and marrow of the Undying Nether Phoenix, this art had undergone a major transformation!
Since the three of them did not dare probe with their Divine Sense, Li Yan had also set down the deadly poison of Pitch-Black Night. Now, he was ready to go all out.
At the instant Li Yan finished gathering his momentum, his entire body abruptly transformed into an ancient ferocious beast, and a huge mouth suddenly opened upon his head.
At the same time, Li Yan's own mouth opened. As he threw back his head, he let out a soundless roar, and invisible sound waves immediately surged into the sky.
As the ancient ferocious beast roared, the space before Li Yan's gaping mouth instantly twisted. Even heaven and earth within the area began to tremble.
With that roar, a pair of crimson wings suddenly sprouted from Li Yan's back, turning him into an upright, vicious demon beast.
His head resembled that of a savage tiger, his body that of a fighting bull.
