I'm doing infrastructure in ancient times

Yaomei and Beast Jiao didn't pay close attention to the coal stone in Cheng Yang's mouth before, but after looking carefully now, they realized that it was no stranger to them.

Cheng Yang didn't expect it to be so dramatic. They searched hard for a long time but couldn't figure it out, but the Beast Horn brother and sister knew it, and it was easy to get it.

Barto looked at the black-painted stones piled up in front of him with an excited expression on his face. Isn't this the coal they were looking for? He couldn't help but stepped forward to pick up a stone, wanting to take a closer look.

Beast Horn's face became a little more nervous, and he hurriedly shouted, "Wait, be careful..."

He couldn't help pulling his younger sister back a few steps, pointing to the stone in Barto's hand with a look of vigilance, "This kind of stone is poisonous!"

Cheng Yang raised his eyebrows, he didn't expect him to say that, did this coal stone poison someone to death?

He looked at the horn calmly, "Did you know that this kind of stone can be used to make fire?"

He originally thought that the brothers and sisters probably didn't know about it. Otherwise, how could these coal mines wait for them to come, and how could they have nodded their heads.

"In the past, people in our tribe used this kind of stone to make fire. I didn't expect that the food that burned out killed many people..." Beast Horn still has lingering fears when thinking of that terrible incident. Many tribesmen fell down in their tribe that night. Woke up the next day, although the body is weak, it will be fine after a while, but some people never wake up again.

It was precisely because their tribe lost too many people that time and their strength was greatly damaged that they were suppressed and bullied by other tribes. He really didn't understand why these two people were looking for this kind of stone.

Hearing that the stone was poisonous, Barto was startled and almost threw the stone in his hand, but fortunately he held back in time. He looked suspiciously at the horn, clearly not believing it.

Cheng Yang had picked up a piece of coal before, and even touched that piece many times, but he didn't see any poisoning.

Hearing Beast Horn said that their tribe was poisoned to death by using coal stones to make fire for food, Cheng Yang thought about it and asked, "Did your tribe eat barbecue that night?"

Beast Horn paused, a little puzzled, what's wrong with eating barbecue? Not only their tribe, but also the surrounding tribes almost roasted the food they hunted. After all, they couldn't find so many stone pots, but At that time, he and his sister were young and the roast meat was too tough, so they were drinking broth at that time.

Cheng Yang didn't know what to say when using coal stones to barbecue meat, but anyone with a little knowledge of chemistry would know that it would definitely cause poisoning, but how could the tribe of Beast Horn know this? He couldn't help but sigh , I have to say that those people died really unjustly.

"These stone entrances are poisonous, and it's fine to use them for lighting."

Cheng Yang explained to them, and picked up a stone to signal them to look at it. Unexpectedly, the brother and sister couldn't help but take a step back, apparently still very scared.

Cheng Yang let out a laugh, and didn't force himself. He picked up a few stones and put them in his arms. He and Barto were walking outside now. It would be much more convenient to use this kind of coal stones for lighting. He planned to pick up some and keep them on his way. use.

He and Barto came here just to inquire about news and find some resources by the way, but now that these two points are almost completed, taking the beast horned brothers and sisters back, they will basically get the news they want, of course they want It is impossible to ask for more detailed information. Even if he and Barto inquired, they would not be able to get the important information. For them now, knowing that the basic information is not much is enough.

And now they have also found a coal mine. It can be said that his previous plan has basically been completed, but how to transport the coal back is a problem.

Cheng Yang didn't expect this to be an open-pit coal mine, and it looked quite small, so it would be easy for them to mine it, but it would be a hassle to transport it back.

Before coming here, he thought that he could bring his tribe to mine and then transport it back directly, but now it seems that it is obviously not possible. When he and Barto came here, it took so many days, and here is not far from the south. A short distance, even greater than the distance between the north and the south, so long-distance transportation is definitely not feasible.

Cheng Yang looked at Barto, "It's time for us to go back."

"Go back? What about these coal rocks?" Barto was taken aback, and turned to look at the mine in front of him. They had been searching for it for several days before, and now they found it and went back like this?Then what were their previous efforts for?

Cheng Yang sighed, there is no way to go back, is there a way for them to transport this back, wanting to find and bring them back are two different concepts.

They now have a direction. After returning to the tribe, they can directly mine as long as they think of a way, which is much better than the previous state of aimlessness.

Barto looked worried, "What if these coals are robbed by others?"

They searched for many days, how did they know that this coal mine is so conspicuous, he can see a lot of black stones at a glance, if they are robbed first, wouldn't their previous efforts be all in vain?

Cheng Yang was not worried about this, he looked at the Beast Horn brothers and sisters, "Many people in your tribe are poisoned because of this coal stone, right?"

Beast horn and Yaomei were taken aback for a moment, and nodded honestly. They didn't think of hiding the news at first, but they didn't expect that this would expose their tribe's strength problem, and then they encountered difficulties.

That's why Cheng Yang dared to go back at ease. The Beast Horn tribe knew the reason because of this coal stone, and those tribes knew the reason.

Hearing Cheng Yang's analysis, Barto was relieved, with a smile on his face, "In this case, let's start early, I want to go back a long time ago."

Even if they were investigating news in the south with the clansmen before, they were not as nervous as they are now. They worried about being discovered by the tribes here every day. These people are not comparable to those in the south. It's a dead end.

Cheng Yang smiled, "Yes, but the food must be prepared first."

Before reaching the south, they had to go through a very barren area, where they could hardly catch any prey. Now that there were four of them, they had to prepare even more food.

Two days later, the four packed up and started their return journey.

Beast horn led Yaomei, and looked back at this place for the last time, they grew up here, and they were tortured here, and now they are leaving, but they don't know what is waiting for them in front of them.

Barto walked for a long time, and when he turned around and saw that the brother and sister were still dawdling, he stopped and turned around, "What? Are you still reluctant to leave?"

Beast Horn hurriedly pulled his younger sister to chase after him. Although he didn't know what was going on ahead, if they didn't follow Cheng Yang and Bar Tuo, they would only have a dead end.

The preparations were well done this time, and the return journey was much smoother than when they came here. Apart from the lack of water, there was almost no danger. By the time they returned to the south, more than half a month had passed.

As they left, they passed through several tribes in the middle of the night, when the moon was hidden in the clouds and it could be said that they could not see their fingers.

"who?!"

"Shh - it's us."

Hearing the familiar voice, the person hiding in the pit quickly crawled out, and lowered his voice in surprise, "Bato? A sheep?"

Suddenly realizing that there were actually two people behind Cheng Yang and Bar Tuo, he immediately became vigilant and almost used the weapon in his hand.

"Don't attack, it's your own!"

Fortunately, Cheng Yang called to stop in time, otherwise the Beast Horn brothers and sisters might have been shot through by an arrow. Cheng Yang quickly introduced the origins of the brothers and sisters to the tribe. He showed a bit of surprise, but after knowing that this was Cheng Yang's arrangement, he quickly accepted it, which was much better than Barto's initial reaction.

From their point of view, since it was Cheng Yang who brought it back, there must be a reason for him. Nowadays, many members of the Jiuli tribe have almost become his fanatics, and now that Barto is on the sidelines, he doesn't say anything. From their point of view, it's even more of a problem.

Cheng Yang thought of being discovered by these tribesmen just after they came back, and laughed, "It seems that you are still very vigilant these days when Barto and I are away."

Now that night is a good time to sleep, he was worried that all the clansmen would be sleeping deeply at this time, and he didn't expect that they would find him before he got close.

Hearing Cheng Yang's joke, the tribesmen in the south were not too excited, but listless.

"You and Barto haven't come back for such a long time, how can we sleep in the mood, we are always worried..."

They were afraid of what would happen to Cheng Yang and Bator, and they were also worried that without Bator here, what would happen if they were accidentally discovered by people from the south? When they saw people from the south approaching their hiding place, they would be shocked Sweating all over, I couldn't help wanting to do it, but fortunately, there was no danger in the end.

Cheng Yang smiled gently, his eyes glowing, "You guys have a good rest tonight, we can set off to return to the tribe tomorrow."

"Departure tomorrow?" The clansmen were startled and couldn't help raising their voices.

"What's wrong?" Cheng Yang frowned slightly, "Don't you guys want to go back?"

"No, no, no!" The tribe was incoherent with excitement, "We have long wanted to go back!"

"That's right! If you and Barto hadn't come back for such a long time, we would have gone back a long time ago!"

"How could we not want to go back, we are so happy!"

"........."

"........."

The joy of the clansmen soon infected Cheng Yang and Ba Tuo, and they looked at each other and smiled. They were worried outside before, but now they feel at ease.

Barto joked with the clansmen in front of him, "I think they are too excited to sleep tonight, and I guess they can't leave tomorrow!"

"Who said that?!" The tribe quickly retorted, "We went to bed early!"

"That's right! We haven't had a good rest for a long time, why can't we fall asleep?"

"Look, Barto, I'm sure I'll be energetic tomorrow, and we must set off!"

The clansmen fired at Barto, but it was not too early at this time. They wanted to set off tomorrow, and now they had to recover their spirits. The group of people could not resist their excitement and fell asleep one after another.

But they are really a bit like what Barto said, as if they were so excited that they couldn't sleep?Hurry up to sleep, hurry up to sleep, the clansmen said silently in their hearts.

At this time, the moonlight came out from the dark clouds again and sprinkled into the pit. Cheng Yang looked at the soft moonlight outside, his body gradually relaxed, and he slowly fell asleep. The smell of corn and rice in the dream was full of heavy harvest.
