After Zhang Heng escaped from the bottom of the lake, he made a trip back to the cave and quietly took care of the two squads. At the same time, he also saw the mute old man, however, he soon realized that the little girl did not return after dark as promised.
Therefore, Zhang Heng comforted the mute old man. He first went to his cave to finish processing the half-finished arrows. Then, he collected some ammunition and a rifle from the bodies of the two squads, after that, he returned to the hillside, but the little girl was nowhere to be seen.
Zhang Heng found a string of strange footprints on the ground. The owner of the footprints came alone, but when he left, there was a string of small footprints beside him.
Zhang Heng knew that the little girl must have been taken away by the intruder.
