Lin Ye was a college student before he was reborn, he was not an expert, but he also knew some common sense of modern science, and also knew the general direction of some science and technology, such as steam engines, electricity, and networks, but when it came to the details, Lin Ye forgot them all in a hurry......

Of course, if you want to develop technology, you have to start from scratch. Lin Ye's tribe is not even Stone Age now. Lin Ye's advantage is that he knows how to start, and he also knows the direction of the tribe's evolution. But the specific things have to be left to their own believers.

For the future of the Phoenix Tribe, the most important wealth is not only Lin Ye's phoenix bloodline, not only the system in Lin Ye's mind, but also the precious knowledge in Lin Ye's mind!!

Lin Ye didn't think so much in his heart, the knowledge in his mind was all the bloody path that his ancestors had walked out with their lives and endless time. Up to now, Lin Ye is equivalent to a prophet with an ancient and peerless secret, if any [Dinosaur Civilization] knows about it, he will definitely catch Lin Ye at all costs.

At this time......

Lin Ye had already flown to the center of the Blood Moon Lake. The lake is so calm that you can't see the end at all...... After Lin Ye reached the middle level of his infancy, he gradually learned what the tentacle creatures did to the entire Blood Moon Lake domain, and his feelings towards the Blood Moon Lake changed slightly.

Anyway, Blood Moon Lake is Lin Ye's birthplace and Lin Ye's hometown, forgetting the unpleasant memories he encountered on the shore of the lake when he was born, Lin Ye already has a sense of intimacy with Blood Moon Lake in his heart.

Lin Ye's figure is reflected on the surface of the lake, and the light blue water surface is extremely clear, and you can see the distance of dozens of meters underwater.

There's a little red dot on the water? Oh, it's a reflection.

Raising his head, Lin Ye found that there was a small red dot on the top of his head, more than a thousand meters above the ground. It is blown by the breeze and flutters with the wind.

What is this?

Lin Ye was full of question marks and flew up. The small red dot gradually enlarged, revealing a blurred outline, a red hot air balloon.

Lin Ye flapped his wings and landed on the hanging basket on the hot air balloon. There were no animals in the baskets, and the fuel basin that provided the heat had been burned dry, and the balloons relied on the residual heat to continue flying, and it would not be long before they fell to the ground.

There were some dinosaur scales scattered in the basket, these scales seemed to have degraded a lot, they were very soft, and they bent ninety degrees at the slightest touch.

Lin Ye saw that there was also a tattered map in the basket, and a shoddy telescope made of wooden handles and miscellaneous glass.

The map details the area where Lin Ye is located, and there is a red cross mark on the map, facing directly east of the Blood Moon Lake, which seems to mark a treasure location.

There should be a "person" on this hot air balloon, why is it missing? Lin Ye thought in his heart, he raised his head and looked into the distance, and gradually had a certain number in his heart.

On either side of the gondola hung four bags of black charcoal, which could be used as fuel, and were handed over to the old caveman to dispose of.

The hot air balloon floated from the east to the west, with the help of the system's analysis of the wind direction, Lin Ye slightly adjusted the flight direction of the hot air balloon, so that the entire hot air balloon could finally fall steadily into the stone tower area, and the old caveman would know what to do.

After putting away the map, Lin Ye also tried the telescope in front of him, the multiple of the telescope was not high, but he could clearly see the texture of the cloth of the balloon overhead. In Lin Ye's eyes, the workmanship of this telescope was very inferior, and it was inlaid with a red gem fragment, not to mention a ruby fragment, even if it was such a complete ruby, there were many pieces in the storage room in the stone tower area. However, the wood of the telescope is very fine, and the wooden handle is very smooth, and it looks like it has been carefully maintained.

Lin Ye was worried that there was something missing, so he searched the hanging basket again carefully, and sure enough, he found a badge carved in stone in the gap of a wooden plank, which looked like a crooked melon and cracked jujube.

Lin Ye tapped on the badge lightly, but didn't find anything special about the badge.

After leaving the hot air balloon, Lin Ye looked back at the hot air balloon again, the entire hot air balloon did not use iron at all, even the fuel basin was made of stone, and the stitching threads on the cloth of the hot air balloon were also made of small animal intestines mixed with a plant slurry. It appears that the tribe that built the balloon was still in the Stone Age, but it may have been outstanding in many ways.

Even in the Stone Age, Lin Ye didn't dare to underestimate it. The Stone Age has different stages, among which the Neolithic is the last stage of the Stone Age, and it is also the stage of material culture development marked by the use of polished stone tools.

After all, in the history of human civilization, there is a very famous stone civilization, that is, the famous Mayan civilization. Although the Mayan civilization was in the Neolithic Age, it had high achievements in astronomy, mathematics, agriculture, art, and writing. He has advanced construction skills, has hieroglyphs, and has made Mayan prophecies, including the end of the world in 2012 AD, which has been adapted into a movie.

"Civilization is a higher stage than the tribe, after the host tribe becomes a third-level tribe, when all the intelligent creatures in the tribe have reached the advanced intelligence, and at the same time control the use of fire and stone tools, it will automatically advance to civilization. ”

It is not easy to advance to civilization, and now Lin Ye's tribe is still a second-level tribe that does not live up to its name.

After the explanation, the system immediately released a mission: "Ding! Main quest released! Raise the tribe to a third-level tribe and increase the number of believers to 100." Quest Reward: The host directly obtains the remaining two Hidden Light Death Fashions, and the quest has no deadline. ”

What is it! Lin Ye's eyes lit up, and he almost fell from the air. When was the system so kind that the remaining two costumes would be used as rewards for the mission.

"This costume was originally a reward for [crafting] in advance, and it was transferred along with the host's time travel. Due to the constraints of the conditions, I can only distribute task rewards to the host after my efforts. The growth system answered, "I have been granted the most basic permission after the autonomous update, and I can slightly change the content and rewards issued by the mission system. ”

Thinking of the many independent updates that the system has experienced before, as well as the merger with the mall system, Lin Ye is thinking, maybe the growth system has really given birth to independent consciousness. He couldn't help but ask a question that had been buried for a long time: "Have you given birth to intelligence?"

The question is stupid. If it weren't for the good performance of the system, Lin Ye wouldn't have wanted to ask.
