1777 The prison of civilization  

Gu Qing Shan looked down at his hands.

After he was done shaping the two sharp rocks, they ripped his skin a little bit, causing him to bleed just a little.

At the same time, the long black hair all over his arms was shed by a small amount.

The ape people were still shouting out loud one after another.

They swung the torches in their hands, trying to ward away the large sabretooth tiger.

Normally, if the prey noticed its approach prematurely, the sabretooth tiger would usually give up on that hunt.
