Since childhood, Yun Zhao has followed his maternal ancestors in the mountains and forests to collect herbs and practice swordsmanship. He is as simple as a cloud and has not been stained by worldly customs. But one day, an ancient prophecy came from the bottom of the mountain: Only those who "have no shadow in the bright moon and no trace in the green front" can awaken the ancient trees that have been sleeping for hundreds of years and save the people from successive years of drought. Yun Zhao had no intention of getting involved in the world, but by chance, on a night when the clear spring reflected the moon, a shadowless light shone on the tip of his sword. The tranquility of the mountains and forests and the call of the village made him embark on the journey.
However, the real test is not a sword fight or a heroic redemption. As Yun Zhao walks around the world, all he encounters are not evil enemies, but "swords" and "hearts" that each protect his beliefs. He played chess with the painter under the flowing clouds, discussed swords with the old man in the bamboo sea, drank tea with the young man in the wilderness - every encounter made him examine the boundary between "saving" and "being saved". Does Jianfeng refer to the external drought or the inner desolation?
This is a story about tenderness and firmness, loneliness and companionship. Yun Zhao's journey is a practice of finding answers in the ordinary, and it is also a gentle questioning of the nature of a "hero". The breeze is bright and the moon is bright, the sword is silent, and the hero's path may finally end with introspection and reconciliation.
