Could it be...
It was not that Xiao Chen had previously held back, concealing the Yin-Yang Force.
Rather...
During the several days he had vanished, he had broken through again and comprehended Yin-Yang?
The more Jin Kui thought about it, the more lost he became in his own speculation. The previous battle had been so brutal, and things had already reached that point. If Xiao Chen possessed such a killing move, there was no reason for him to hide it.
Yet Yin-Yang life and death was a supreme Dao, obscure and profound. Jin Kui had once had a close friend of peerless talent, someone who had stunned the Demon Domain. That friend had spent over three hundred years painstakingly seeking the true essence of Yin-Yang, exhausting all his heart's blood, only to gain nothing in the end. Finally, he had given up in despair.
Jin Kui could not believe that a mere youth had comprehended Yin-Yang in just a few days and could wield the mighty power of life and death!
How could such a monstrous genius exist in this world!
"A draw?" Ke Hei was astonished. Facing such a heaven-shaking, earth-rending blow, Xiao Chen had actually not fallen into a disadvantage?
Who was Jin Kui? A peerless demon, an invincible Quasi-Emperor who had once single-handedly swept through nine city lords without injury. Even though he was now severely wounded and unable to display his full strength, he remained incomparably ferocious. How could he be stopped by a Fourth-Level King Realm youth like Xiao Chen?
After all, Xiao Chen did not have the True Demon possessing him now. He was fighting entirely with his own cultivation.
"Looks like the Yin Spirit Scythe is even more terrifying than we imagined. When fighting Wu You earlier, Master never unleashed its full limit!"
