These people actually managed to conquer the land. What Meng Chuan really wanted to paint was this story of land conquest.
In the early days, the human race was nothing to speak of when it came to conflicts between species.
When it came to this generation of humans, they formed a spirit of conquest due to the environment and other factors. With just 15 people, they relied on their two legs and passed on the torch for generations! They actually traveled across the land and became the ruler of the entire continent.
In that primitive era, this was an unimaginable miracle.
