As time keeps getting closer to the arrival of the caravan, Dong Chen becomes more and more busy.

Not only can you not lose your studies with the Great Elder, but you also have to go out with the hunting team to hunt and gather.

At the beginning, Dong Chen only collected precious medicines and then processed them according to traditional methods within the tribe, so that the medicinal materials could be preserved for a long time without losing the efficacy as little as possible.

While practicing, let the Book of Heaven summarize these methods and then see if you can calculate a more optimized method.

Some of these methods have been optimized, but other methods can really be upgraded. Dong Chen did not secretly hide the upgraded methods, but handed them to the people in the tribe, and let the great elder record them in his own book.

After living in the Giant Rock Tribe for a long time, Dong Chen always planned to do something for them and let the Great Elder's books read more.

"If you see it, use this method to better handle the quality of the medicinal materials, and you can get more money in the past."

"A herb can be sold a little more, but if you sell a basket, it will be a considerable fee."

"Aunt Tokoma, this kind of fur must be treated like this. The Great Elder wrote it in the books. After processing, the fur will be more beautiful and softer, and will be more popular among the human race and can be sold for more money."

Although Dong Chen tried hard to introduce them to the method, the barbarians who lived in the forest all year round could hunt for meat and make their own seeds when they wanted to eat. Money was really of little use to them.

So people often ask such questions.

“What should I do if I sell…more money?”

"The Great Elder's book is too complicated, and it hurts if you read a page."

OK, I need to change my strategy.

Dazhuang needed to learn carving tools to be more professional, so Dong Chen found the only blacksmith in the clan and discussed the creation of new tools.

After discussing, Dong Chen took out his dagger.

"Uncle Togong, how do you think of my knife? Isn't it very delicate?"

Togong took Dong Chen's knife, looked at the layers of patterns on the blade, rubbed it with his big hand like a palm fan, and looked intoxicated expressions that were very similar to Da Zhuang, "It's very exquisite. I have never seen such a knife before. Its construction technology must be very amazing. I don't know how taller it is than me."

As he said this, he looked at Dong Chen with a pity, "It's just a little too young. If any kid gives me a hunting knife like this, I will definitely marry my daughter to him."

"Ahem" Dong Chen was embarrassed and took his knife back, "It doesn't matter if he has the technology, if you want to build a bigger one, it's the question of how much material is used."

"Uncle, you also said which kid gave you a hunting hand and then married his daughter to him. Aren't you bothering about your kid's iron mattress? Just let him learn ironworking skills in the human race. When he comes back, he will create a knife like this to send it out. Wouldn't it be easy to get married?"

"And he has learned this technique, and your grandson, great-grandson, and all descendants will no longer make things difficult for marrying a wife!"

Listening to Dong Chen's story, Togong was very motivated, but he said with some embarrassment, "I know this, but unless the blacksmith takes the initiative to accept students, it costs money for ordinary people to learn technology. I don't have many human coins here, what should I do?"

"Now there is a chance," Dong Chen was waiting for this sentence. "Just treat the fur and herbs as I said, and they can be sold at a good price. Wouldn't you save enough money soon?"

"What you said is really useful?" Togong asked with a heart-warming look.

"Of course," Dong Chen patted his chest, "I guarantee my personality."

"And the methods I mentioned were actually recorded in the Great Elder's book very early. Because you didn't read the book, you have missed a lot of money to learn technology over the years. Otherwise, your iron felt would have learned superb ironworking skills, and you might have been holding a grandson a long time ago."

Togong: "!!!"

Barbarians are not very enthusiastic about money, especially for such barbarian tribes living deep in the forest. They can only be made by self-produced and sold, and hunting, etc., so they can only buy some things that they don’t have here.

Of course, this is the reason why there is little contact with human society.

However, once we talk about the issue of inheriting the family line, it is a very serious issue. This is the responsibility of every barbarian, which is only engraved in the bones.

The barbarians will never experience the phenomenon of not getting married or having children.

Dong Chen suspected that this was the biological scientists who tampered with the genes of the barbarians, so he directly used this method.

Compared with the issue of inheriting the family line, what is the book of reading?

"Dong Chen, I understand."

Togon said with a serious expression, "Today I will let Tokoma deal with the medicinal materials and furs as you said before, and then let the ironworker go to the Great Elder's library to read books to see if you can find other useful things."

"If you can find it, tell the others in the clan so that they can save more money."

Dong Chen's method is not only effective for tribute, but also for everyone in the clan, because even if they don't worry about their son getting married, they will worry about other things.

For example, I want to buy a beautiful and gorgeous jewelry for my wife as a family heirloom, and I want to add something to my family, but there is no one in the clan, so I can only buy it in the human world, etc.

These all require money.

In the past, they only bought some daily necessities, such as refined salt, sugar, etc.

They had a good-looking canvas, refined furniture, sharp hunting knives, etc., before, but they were not urgent. Now their needs have been stimulated by Dong Chen.

Although living is enough to eat, you always have to pursue something other than basic living.

Dong Chen combined their needs and then grafted the answers to the books of the Great Elder, so that they could find the answers from the books of the Great Elder, which made the Great Elder very happy.

Looking at the lively "village library", the elder was very pleased and patted Dong Chen on the shoulder and said, "Dong Chen, you really have a way. You have to let so many people read books in one go."

"This is actually not a solution I thought of myself. I just used it," Dong Chen was very modest about this, looking at the lively library. "In this way, although everyone cannot like reading, I believe there will always be one or two people who can understand the benefits of reading."

The elder touched his beard and looked at all this with a smile, nodded in agreement, "Yes, I feel so too."

During this period when Dong Chen came, he did bring a lot of changes to the Jushi Tribe.

It started out with the changes in food.

With Dong Chen, a Chinese on Earth, you must not be careless when eating. In this way, the dining table of the Giant Stone Tribe has undergone very rich changes, and the grill uncle has learned more ways to make food.

Then this technological upgrade made the entire tribe operate and a different atmosphere.

Originally, Dong Chen felt that the method of pulling animal mills was slow and time-consuming. When he planned to build a wind mill or a hydraulic mill, he was stopped by the Great Elder with a smile.

The Great Elder found a book for Dong Chen to read, and there was a wind mill-like device on it.

"Great Elder, since you have this kind of device, why not use it? Isn't this more advanced and more labor-saving?"

Dong Chen was a little confused.

"It's very advanced, but it's not suitable for us. If our Boulder Tribe is a town, I would definitely use it, but we're just a tribe."
