The Only Player in Prehistoric Times

Chen Xuan picked up a very beautiful piece of porcelain with extremely complicated patterns. At first, the pattern seemed to be chaos, but upon closer inspection, I found a continent floating in the chaos. Staring at the center of the continent, I found that it was a big mountain. Looking closer, I found that there were dragons and phoenixes dancing on the mountain. I moved my eyes to the north and found a vast ocean. Then I looked carefully and found that a big fish in the sea turned into a big bird after leaping out of the water with all its strength.
