After a long argument, Heng'e got angry and chased Xuanqi out and Shen Lian finally had the chance to witness Heng'e's techniques.
Heng'e took out a silver hairpin from her hair and gently stroked it. A Milky Way then appeared between her and Xuanqi. Xuanqi attempted to cross over the Milky Way but regardless of how fast he was, he just failed to cross over. This was because as Xuanqi moved, the Milky Way would expand concurrently. As long as Xuanqi did move, the Milky Way would not stop expanding.
Heng'e's supernatural power reminded Shen Lian of the monkey from 'Journey To the West', who failed to escape from Buddha's palm. This supernatural power was known as the 'Buddhist Kingdom on the Palm' among the Buddhist sects.
Xuanqi eventually gave up. He took a step back and exited the Milky Way. Before he left, he angrily said, "My sister, you are so cruel."
