Looking at the black smoke rushing into the sky, charcoal burning begins, and the process takes about a week.

The planned gold and stone tool is still just meteorite, and it is just right to take the "Bull Demon King" out for a walk in his busy time, and he will be about to go home in the light plan, because it will take too long to come out this time.

According to the memories of his later generations, these places west of the Yellow River did not have the kind of environment of later generations, a wasteland with yellow and green, so much so that it was mistakenly thought that this was the Inner Mongolia Plateau.

The humidity in the early morning air is very high, and it may be that this place is close to the Taigu River, and the prehistoric environment has not been destroyed.

Yu Guang was riding on the fat and strong Mongolian horse, but the one leading the horse was not the "second junior brother", and the height of the "Bull Demon King" was now almost reaching the chest of Yu Guang, who was riding a horse.

"Brother Guang, I'll be to that place in front." The Bull Demon King said.

During this time, the "Bull Demon King" was also accustomed to being called like this by the light, and the "Light Warrior" and "Brother Light" sounded really awkward to him.

"Then hurry up, I'm going to see what kind of moth this ruin is!" Yu Guang said seriously, and then gently kicked the horse's belly, and the Mongolian horse's speed was raised. And the "Bull Demon King", a wild primitive person, is not slow to run with all his might, which makes Yu Guang a little impressed.

After a meal, the two of them came to the front of the ruins mentioned by Bi Niu, which is in the north of the Tianhuo tribe, surrounded by mountains and rivers, and belongs to the standard prehistoric human existence, but now it is a mess.

You can almost see the remnants of a lot of tall shacks, and when you walk into this ruin, the blue sky is extraordinarily high, and Yu Guang is a little distracted.

Perhaps immersed in the stories that may have happened here, suddenly there was a lonely eagle cry in the sky, which brought Yu Guang back to reality, so he refreshed himself and asked the "Bull Demon King": "Old Niu, you said that in the Tianhuo Tribe, how can the clansmen preserve the past stories?" ”

The "Bull Demon King" rolled his eyes for a while and then rolled his eyes and replied, "Tell the cubs!" Eh~ Sometimes the old witch will also use black clay to paint in the cave. ”

"That's right! In the cave... How did you forget about this stubble! Yu Guang laughed at himself.

After tying up their horses, the two walked to the bottom of a low hill at the other end of the ruins.

It didn't take long to find a man-made cave, it was noon at this time, the cave was well ventilated and the light was very good, the two observed for a while, and felt that there was no danger and walked in cautiously.

The cave was very clean, and there was surprisingly no dust, which made Yu Guang frown slightly, and his right hand quietly stretched out to the place where the dagger was pinned to his waist, but he didn't say it.

The further he went, the light gradually began to dim, and Yu Guang lit a torch made by the "Bull Demon King", which was a pine stick wrapped around a piece of skin stained with animal fat, so it smelled very bad when burning.

It wasn't until he went to the deepest part that he finally saw a wall that had been cleaned up and graffiti-like, Yu Guang looked at the things on it dumbfounded, like a masterpiece of painting ghost talismans, he couldn't understand it.

"Old Niu, what is painted on this?" As a native primitive, he feels that the "Bull Demon King" can probably understand.

I saw the "Bull Demon King" pinching his waist with one hand, touching his hedgehog-like head with the other, looking at the wall illuminated by the light, and studying it for a while.

Silly laughed and said: "Here is the flint from the sky, their old mother led the tribal leader to continue to swallow up some tribes on the edge of the burning earth, so it became a large tribe in this area, they tamed the big birds, became a hunting tool, eh~ Later, they continued to search for small tribes in the land of icebergs..."

He said for a long time in one breath, Yu Guang handed over a bamboo tube, and the "Bull Demon King" took a sip of water, slowed down and was about to continue, but hesitated for a while and said, "That's not right!" That... This... Something is wrong..."

After Yu Guang heard what he said, he immediately held a torch and shone it in the direction of the finger of the "Bull Demon King", "That's a fire, right?" ”

"Yes, Brother Guang, what I said above is probably that a group of demons came out of nowhere, ate all the people in the tribe, and burned the entire habitat with a fire..."

Yu Guang frowned again, he felt that this tribe should not have been killed yet, and it was still living here, and the mural in the back was added by that person.

However, the kid "Bull Demon King" doesn't bend his brain, and according to his analysis, everyone is dead, how can there be a story behind the mural.

I saw the "Bull Demon King" trembling and said: "Brother Guang, let's go, this place is weird, I'm afraid there are ghosts and gods!" ”

Yu Guangle is happy, this guy is really timid.

"If there are ghosts and gods, I am still a celestial, when I became the leader of the clan, they said that I was a celestial! Don't be afraid, there are three fires on the head of the living, and if you are weak, it will be strong! ”

At this time, the horse tied to the mouth of the cave barked.

"Oops! Old cow is fast~ There is a thief stealing my horse! Yu Guang pulled out the bronze dagger and rushed out, and the "Bull Demon King" was not slow to follow closely.

However, as soon as they ran out of the hole, something happened, and Yu Guang found that they were surrounded by a group of primitive people with crocodile heads on their heads, holding bone spears.

The "Bull Demon King" quickly pulled out an axe that Yu Guang made with meteorite behind his back, but the visitor didn't give him a chance, only to see a female voice from the opposite side, "Big man!" Keep your stone axe still on the ground, or you two will be pierced by our bone spears! ”

The woman in front of her was not very tall, about one meter six, although she was thin, it could be seen from her bare arms that this woman was very good at fighting, judging from her voice, she was about eighteen or nineteen years old.

Seeing that the situation was weak, Yu Guang hurriedly grabbed the "Bull Demon King" and smiled: "The king spares his life!" We are from the Tianhuo tribe, great good people! ”

In fact, after he came out, he glanced at the other party's clothes, and almost all of his body was covered with bone weapons, only the woman in front of him was carrying a stone spear in her hand. And all the accessories and bone tools on the body are not human bones.

According to the time when Yu Guang came to prehistory, he also concluded that as long as the other party did not wear human bones, they were considered enemies and could be fooled by peace talks. Just like the Ulla, the human bone accessories must be removed immediately at first sight!

Moreover, he was not far from this female leader, and he could clearly smell a faint fragrance emanating from the other party, which was a little inconsistent with the crocodile head she was wearing on her head.

He knew that in this era, as long as he didn't panic, he would not have any difficulty in being bold and careful, so he quickly retracted his bronze dagger from his waist while she was not paying attention.

It just so happened that the other party also surprisingly cooperated with Yu Guang, maybe seeing him stop the "Bull Demon King" from taking weapons, at this time he said very funny: "What are you doing?" What are you doing here? ”

Yu Guang sneered and said secretly: "Sister, you are from the island country!" "It's good that I didn't dare to say it.
