Till now, Hall Master Xing had always referred to that person as 'big trouble', and he had not said who the person was.
As such, Zhang Xuan had no idea who the other party was. All he knew was that the other party was an extremely skilled individual who possessed fighting prowess at the peak of his cultivation realm.
As one who had cultivated the Heaven's Path Divine Art, he was confident that he would be able to subdue any opponent in the same cultivation realm easily, but he did not believe that he was truly invincible. After all, his clone was always around to remind him not to get complacent. Since his clone was able to attain strength far greater than him, surely there would be some amazingly talented cultivators in the world who might have been able to do the same.
As such, from the start to the end, he had never doubted that the 'big trouble' Hall Master Xing referred to could have been referring to him.
