Tao Zun in the Prehistoric World

Ye Yun traveled through time and got a sign-in system. As long as he signs in every day, he can get sign-in value and random rewards. At first, Ye Yun just wanted to be a low-key signer, living in this world in a cool and unrestrained way. But the strength doesn't allow it! When the host signs in for the first time, he will be rewarded with one 5-cubic system space, a Li Xunhuan possession card, and a double sign-in card.
