Li Gongyun and Leng San used a light-body technique, heading out of the Main Branch of the Institution. They traveled for more than half a shichen until they reached a high-mountain region. Li Gongyun headed up to the top of the mountain, with Leng San following behind.
Throughout the journey, the two did not utter a single word. Leng San was full of questions to ask. The man, who could give him a final clue and who was the only one who held almost the whole story, was his Master.
Arriving at the summit, it was in the middle of the night, and the full moon shone in the sky. Li Gongyun stopped his feet on the highest peak of the summit, glancing at the moon and the ground while showing a hard look on his face all the time.
In the end, Leng San could not wait any longer, so he asked first.
