The weather in the Prehistoric Era is unpredictable.
One day it's scorching hot, and the next it might be freezing cold.
However, beasts have thick skin and flesh, so such temperature fluctuations don't significantly affect them.
But it seems Tu Yan's resistance has weakened; as the night cools down, he curls up entirely.
Chuzheng sits nearby, watching Tu Yan, and only when frost begins to form around them does she get up to wrap him in her embrace, covering him with her feathers.
Phoenixes are naturally attuned to fire and their bodies are warm.
Tu Yan gradually relaxes.
-
In the latter half of the night, a thin layer of ice forms all around.
Tu Yan wakes up in warmth, looks up, and sees the Phoenix's beautiful feathers; she has enveloped him with her wings, and his whole body is lying on her.
"Awake?"
Tu Yan raises his eyes, and at some point, the Phoenix has opened her eyes, staring intently at him.
