Twenty years have passed, and the Styx tribe has added many children, and fewer and fewer adults have stayed in the tribe, all working hard to go out to hunt and gather to feed the increased population. There were several adults teaching the children martial arts in the tribal square, while several disabled people and some women were handling prey and gathering plants and fungi.

On the savanna, herds of herbivores are flocked, some reptiles have thick bodies, hard skin, some have sharp horns, and some have a row of spines on their backs. There are also half as good as reptilian muscles protruding from sparse hair, and they seem to be in good physical strength. There are also a small number of mammals, which have long slender bodies, neat hair, and long manes on their backs, and are known to be known for their speed. Under several thick trees lay a group of carnivorous semi-mammalient reptiles, their muscles thinner at the ends, their heads long, their teeth sharp, and the two canine teeth on their palate that were closed and longer than their chins. There is a large lake far away, many animals are around the lake, and from time to time there are water splashes on the lake that are violently twisted, which can be judged to be crocodiles preying on the animals on the shore, and some birds fly up and down from time to time.

On a pile of huge rocks, five men in leather armor stood, led by Koronos, who carried a sword on his back and a dagger in a leather sheath pinned to his waist, the dagger was thin and curved, and the handle was made of patterned wood. On a long belt hung an ostrich egg-sized egg, with a wooden plug on it, presumably a kettle. To his left were three grown men, one of whom had a wooden plank, thick in the middle and thin in the edges, and covered with obsidian flakes on the edges, and it would have been terrible to imagine if it had been cut at someone. The other two each took two spears, and the tips were made of bone and obsidian, respectively, and the polished bony tips looked sharper. On the right of Colonos is a young man, his wings are very special, the white wings have a row of golden feathers on the edge, which looks very beautiful, he also carries a sword on his back, and he and Colonos are the only ones of the five who do not have skull decorations. The boy looked very sunny, and his dark eyes looked at the animals below eager to try.

Colonos looked down and said, "Ryan, see how many you can kill." Hearing this, the young man nodded, took a few steps back, pulled out the sword on his back, and then jumped out of the boulder with a sharp dash, spread his wings and glided for more than twenty meters, looking at a half-mammalian reptile with long horns, his wings immediately contracted and fell quickly, holding the long sword with both hands and thrust it downward. The long sword directly stabbed the animal's cervical vertebrae, and Ryan's feet happened to step on the animal's back, and the surrounding herbivores were frightened and ran away, he kicked and jumped up with both feet, and the long sword slashed down hard, and the neck of an animal was aimed at cutting off most of its waist directly. Hunting has always been like this, once the prey starts to run away, you have to hurry up and use the fastest speed to get the most out of it, and now the prey has begun to flee, Ryan is chasing after a prey, but he can only barely keep up. At this moment, a bony spear spear shot from behind and pierced a prey more than ten meters to Ryan's right, the prey immediately fell, and another bony spear fell from a high place and stuck in the hind leg of a prey, which fell to the ground after running a few steps, twisting forward with force. It's a long story, but in fact the two spears stabbed the prey for less than 2 seconds, and after seeing it, Ryan shook the sword hard, and the sword spun and flew out, cutting off the two hind legs of the prey he was chasing, and the sword body was half submerged in the earth, and the animal also fell to the ground, some funny, Ryan rushed up and pulled out the sword and stabbed it into the heart, and it was killed. The other two also rushed up and killed their prey, and Colonos slowly walked over and said, "The hand is a little slow, it's okay, the slash is strong enough, you need to practice your speed more." "Yes, Chief." Ryan replied.

The man with the obsidian plank grabbed the leg of a prey in one hand and dragged it over, he looked around and said, "Let's bring the prey back first, or it will soon attract hyenas." (The hyenas here are not modern hyenas, but the realm of the gods at that time already had canine suborders and carnivores, more than 10 million years earlier than other continents.) Colonos said, "Ryan, you help with the weapon." He turned to the man with the obsidian plank and said, "Kros, you three bring your prey." With that, he walked ahead. I didn't go far, and there was a "woo woo ?????" from the original direction They continued to walk back in the direction of the tribe, and soon there was a "rustle?????rustle" behind them. Behind the sound, a group of hyenas appeared, they are very similar to modern hyenas, but they are very large, with an average height of 1.5 meters, black facial circles, black eye circles, and yellow bodies, with vertical sparse black pinstripes. Colonos said, "Keep walking." Then he stayed behind, and the hyena slowly approached him, and suddenly he opened his arms and wings and yelled at the hyena: "Hungry! The hyena in front hurriedly took a few steps back, "Woo woo woo ?????" The sound was more continuous, a hyena slowly moved forward to Koronos, trying to attack him, getting closer and pounced on him, Koronos turned around, and the hyena was in unison, his left hand grabbed the hyena's throat from below and pulled it down, his right hand became a knife, and he slashed down, just at the joint of the hyena's shoulder blades and front leg bones, the hyena immediately lost his balance due to joint dislocation, and overturned, and after getting up, the three legs supported his body and dragged the dislocated leg backwards, away from Colonos.

Just as a few hyenas in the back came up, suddenly "cats????? (Cat meows, many times cats don't meow, but cats)" a very penetrating sound sounded, and all the hyenas' bodies began to tremble, and some began to spin in place, and then gradually moved away from the place. "Stop, stop." Colonos shouted to Ryan and the others, and then quickly followed, "Cat????? (Cat's meow) "Again," "be careful, pay attention to all movement around you." Colonos said to them solemnly. Everyone put down their prey and took their weapons and carefully watched the surroundings, Colonos slowly pulled out the sword on his back, put the kettle on the ground, and listened carefully to the surrounding sounds, the trees here are denser than elsewhere, and there are some large stones, which are not as clear as other places, plus the cat never makes a sound when walking, so it is difficult to be spotted.
