As Suiren, Youchao, and Ziyi taught humanity how to make fire, build houses, and craft animal-hide clothing, they made survival far easier.
Originally, humans had very short lifespans. Aside from those killed by Fierce Beasts while hunting, many also suffered from Severe Weather and eating raw meat. Bacteria from Fierce Beast meat entered their bodies and severely shortened their lives.
However, after Suiren invented the method of making fire by drilling wood, humans stopped eating Fierce Beast meat raw. The beasts brought back each day were roasted by the women of the tribe and those recovering from injuries. This greatly strengthened their constitutions, and few people in the tribe fell ill.
The methods of building houses and making animal-hide clothing that Ziyi and Youchao brought to humanity also greatly improved their living conditions. People no longer had to live in cold, damp caves, and they now had protection against harsh weather.
Moreover, these hide garments and houses could offer some protection against Fierce Beast attacks, greatly improving humanity's chances of survival.
Suiren, Youchao, and Ziyi were also the strongest humans in the tribe, and they had brought their people ways to grow stronger and better living conditions. Gradually, the tribespeople came to regard the three as their leaders, following them as they struggled to survive in this harsh environment.
Time slowly passed, and fifty years went by in the blink of an eye.
Thanks to the efforts of Suiren and the other two, humanity's living conditions improved dramatically. Combined with the strong bodies they gained through practicing martial arts, this allowed their population to spread rapidly.
Twenty years earlier, humans had already spread throughout the entire mountain range and eaten every Fierce Beast within it. To survive, they began expanding beyond the mountains into lands they had never set foot
