Comment:Legend of Sword and Fairy 4


One possible explanation:Yun Tianhe's unchanged young appreance is said to be attributed to the Divine Dragon's power.(which is mention above) But Liu Mengli does not know any of this experience. She thought both Yun and Han were dead when she comes back 100 years later(She is a demon, so she do not grow old then). Thus, the appearance of Yun may really suprised her. And it can be consider as a happy ending that Yun and Liu lead a peaceful life there.
