A man in the rainbow
As the bamboo raft advances, it can be seen straightening out after four or five bends, and the water flow gradually accelerates. North does not dare to be careless, closely observing the environment with her consciousness. Her feet are parallel to her shoulders, maintaining a stable stance. In her hands, she carefully controls the balance point with the pole. After about an hour of maneuvering, she finally passes through this canyon. Feeling a bit exhausted, with heavy eyelids, and before she can buffer herself, the turbulent water pushes the raft and its occupant into a massive cave entrance.
The sound of rushing water is exceptionally magnified within the cave, resembling a tiger's roar in the woods or the mythical dragon's roar. The spacious hall is about the size of four or five football fields, with a ceiling about twenty to thirty meters high. Large yellowish stone curtains and shields hang down, and a sparkling white stalactite stretches across them. Facing the cave entrance is a small, horned, and short stalactite, with mustache-like formations dancing in the air, massive like a dragon's head. It radiates a dazzling light, resembling a young and proud white dragon leaping boldly between heaven and earth. Unaware if anyone has been here before, North decides to name it the "White Dragon Stone," and this place will be called the "Dragon Cave." The water flows forward along the dragon's body, gradually calming down at the dragon's tail, gathering into a small lake with a diameter of a hundred meters. The light in the cave is extremely dim, with only the "White Dragon" resembling lightning tearing through the sky in the dark night, like a general setting out for a night campaign, adorned in a dazzling white battle robe, pointing its sword towards the sky.
Despite being physically drained, feeling as if nerves are being constantly pierced by thousands of silver needles, sharp pains persist. In this pitch-black darkness, other than forcibly using space to observe the environment and find a way out, North has no other choice. The lake water overflows in the direction of the White Dragon, along the vast lotus stone slope, flowing towards the bottom of the cave, forming an underground river that goes deeper and farther. Nearby is a five-meter-wide channel with a drop of nearly two meters, North tightly focuses on space, cautiously controlling the bamboo raft down the waterway. After traveling for about five miles, there's a faint light coming in, and they should be nearing the cave entrance. Biting down on her lower lip to endure for half an hour, she finally sees the red clouds in the sky under the setting sun after passing through the half-mile-long Swallow Cave entrance.
Looking up from the north, the valley opens up, and water flows gently from the mountain slopes. Tributaries from waterfalls hanging down the mountain join the clear river. The evening sun shines on the waterfall, reflecting a dazzling seven-color rainbow. The flowing water impacts a bare-chested man, a bare-chested man? A bare-chested man!
