The Most Powerful Development System in History

When I woke up, I found that I had traveled to the prehistoric times. However, Wang Tiansheng is not in a hurry because he carries a Shan Hai Jing development system with him. Is the saint very fond of you? The Kun-Eating Ape and the Bone Kun will crush you every minute. Is Hongjun very attractive? Look at my number one general, Shen Kun, crushing you in seconds. For such a troublesome system, Wang Tiansheng embarked on the road to win the beauty back. Let me say this in advance: If you don't like it, you can leave, but please don't complain.
