Duan Ling Tian was rather taken aback when he heard the cyan-clad young man was a Celestial Emperor whose strength was comparable to a titled Celestial Emperor despite only being slightly over 800 years old. Among the people he knew, only his Eldest Senior Sister from the Heavenly Pool Palace could be considered a rare genius. Even then, she only possessed such strength when she was past the age of 1,000. Although she progressed tremendously after passing the age of 1,000, to the point where she was as strong as the Palace Master of the Heavenly Pool Palace, her achievements before the age of 1,000 could not compare to the cyan-clad young man from the Mystic Sword Sect at all.
