Nothing happened at night. There were occasional sounds of wild animals in the pine forest, rustling in the distance, but they didn't come close. At dawn, Zhang San woke up from the cold. His legs were so numb that he couldn't stand up. He had to rub them for a while before he felt better. Li Si was still sleeping, his face looked better than yesterday, and there was a little blood on his lips. Zhang San didn't call him, he walked out of the concave rock, walked around in the forest, and found a mountain stream. The water was so clear that you could see the pebbles at the bottom. He squatted down, took a few sips of water, and wiped his face with wet hands. The cold stream water made him shiver, but he also woke up completely.
There were footprints on the mud beside the stream, fresh human footprints, small in size, like those left by a half-grown child, going deeper into the forest. Zhang San squatted by the stream and watched for a while, memorizing the number and direction of the footprints, and then turned back to call Li Si.
