Being pulled by the power of Sundial, Zhang Ruochen entered a special inner space.
This space was not too big. It was like a cave without an entrance, surrounded by rough stone walls.
Zhang Ruochen had obtained Sundial for a long time. He often cultivated with it, but he didn't know there was a space inside it. Let alone the possibility to enter it.
Looking around, Zhang Ruochen found that everything in this space seemed very primitive and ancient. Several rough stone tools in the corner, such as stone jars, stone knives, and stone axes. They were all only roughly shaped, and the edges weren't neat.
In the center, there was a long-extinguished fire. Many animal bones were scattered around, with most of them rotten.
Zhang Ruochen couldn't help but feel like he had traveled through time and entered a cave where primitive people lived.
