Yushen, Yunho, Su Na and others participated in a northwest expedition and came to Qinghai Lake. While admiring the breathtaking scenery, they encountered the incident of their companion Yu Jia mysteriously walking into the lake and drowning in the middle of the night. This is not an isolated case, there have been many similar disappearances before. In order to find the truth, they decided to stay and investigate, pursuing a mysterious and dangerous figure-Master Zeji. At the end of the story, they returned to Qinghai Lake with the "Qinghai Lake Orchid" given by Master Zeji and finally released it into the lake. This action symbolizes the choice they made: everything about Yu Shen, including responsibility, love and life, is not in the sacred but lonely beautiful world of Qinghai Lake, but in the real world.
Purpose: Can we find the beauty of loneliness in the struggle of reality?
