As the time approached the day when the caravan was coming, Dong Chen became more and more busy.

Not only did you not fall behind in your studies with the Great Elder, but you also had to go out with the hunting team to hunt and gather from time to time.

In the beginning, Dong Chen only collected precious medicines, and then processed them according to the traditional methods within the tribe, so that the medicinal materials could be stored for a long time with as little loss of efficacy as possible.

While practicing, let Tianshu summarize these methods, and then see if you can calculate a more optimized method.

Some of these methods have been optimized, but other processing methods can really be upgraded, and the upgraded methods Dong Chen did not hide them privately, but handed them over to the people in the tribe in one go, and let the Great Elder record them in his own book.

After living in the Boulder Tribe for a short time, thanks to these simple and honest people in the tribe taking such good care, Dong Chen always planned to do something for them, and by the way, let more people read the Great Elder's books.

"See, you can use this method to better deal with the quality of medicinal materials, and when the time comes, you can make more money than before."

"A herb can be sold a little more, but if you sell a basket, that's a considerable expense."

"Aunt Tokoma, this kind of fur must be like this when it is handled, it is written in the Great Elder's book, and the fur after processing is more beautiful and softer, and it will be more popular among the Terrans, and it can be sold for more money."

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

So people often ask questions like this.

"Sell...... What to do with more money? ”

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

Well, it's time for a change of strategy.

Da Zhuang needs to be more professional in learning carving knives, so Dong Chen found the only blacksmith in the clan, and then discussed the creation of new knives.

After discussing, Dong Chen took out his dagger.

"Uncle Togon, what do you think of my knife? Isn't it exquisite? ”

Tuogong took Dong Chen's knife, looked at the layers of lines on the knife, rubbed it with a big hand like a fan, and had an intoxicated expression very similar to Da Zhuang, "Very exquisite, I have never seen such a knife, its building technology must be very amazing, I don't know how much higher than me." ”

Saying that, he looked at Dong Chen with a little pity, "It's just a little too small, if any kid gives me a hunting knife like this, I will definitely marry my daughter to him." ”

"Ahem" Dong Chen was a little embarrassed and took back his knife, "It's okay to be small, when you have the technology, if you want to build a bigger one, it's a matter of how much material is used." ”

"Uncle, you also said that which kid gave you such a hunt, and married your daughter to him, aren't you worried about the marriage of your kid Iron Felt? You just let him go to the human race to learn the art of iron, and when he comes back, make a knife like this and send it out, then wouldn't it be easier to marry a daughter-in-law? ”

"And he learned this technique, and in the future, your grandchildren, great-grandchildren, and all future generations will no longer be embarrassed to marry a daughter-in-law!"

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

"Now there is a chance," Dong Chen waited for this sentence, "as long as the furs and herbs are processed according to the method I said, they can be sold for a good price, won't you quickly save enough money?" ”

"Is this really useful?" Togon asked, heartily.

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

"And the methods I mentioned, the Great Elder's book actually recorded it a long time ago, just because you haven't read the book, so how many money have you missed over the years to learn technology, otherwise your iron felt would have learned superb iron-striking skills a long time ago, and you might have hugged your grandson a long time ago."

Togon: "!! ”

Barbarians are not very keen on money, especially this kind of barbarian tribe living in the depths of the big forest, self-production and self-sale plus hunting or something is enough to live, and only some things that they don't have here will be bought with money.

Of course, this is also the reason for the lack of contact with Terran society.

However, once it comes to the issue of inheritance, it is a very serious issue, which is the responsibility of every barbarian, and it is only engraved in the bones.

Barbarians will never marry and have children.

Dong Chen suspected that those biological scientists had manipulated the barbarian genes at the beginning, so he directly used this method.

Compared with the issue of inheritance, what is it to read a book.

"Dong Chen, I know."

Togong said with a serious face, "Today, I'll ask Tokoma to dispose of the herbs and furs in the same way you said before, and then let the Iron Felt kid go to the Great Elder's library to read and see if he can find anything else useful." ”

"If you can find it, tell the rest of the clan so they can save some more money."

Dong Chen's method was not only effective for Togon, but also for everyone in the clan, because even if they didn't worry about their son marrying a daughter-in-law, they would worry about other things.

For example, I want to buy a beautiful and gorgeous jewelry for my daughter-in-law as an heirloom, and I want to add something to the family, but I don't have it in the clan, so I can only go to the human world to buy it, etc.

These are things that require money.

In the past, they would only buy some necessities, such as refined salt, sugar, etc.

Good-looking canvases, refined furniture, sharp hunting knives, etc., they also needed them before, but they were not urgent, and now their needs have been stimulated by Dong Chen.

Although it is enough to live by eating, there is always something else to pursue in addition to basic life.

Dong Chen combined their needs, and then grafted the answer onto the Great Elder's book, and let them find the answer from the Great Elder's book, which made the Great Elder very happy.

Looking at the lively "Village Library", the Great Elder was very pleased, patted Dong Chen's shoulder and said, "Dong Chen, you really have a way to let so many people come to read at once." ”

"This is actually not a method I came up with by myself, I just used it," Dong Chen was very modest about this, looking at the lively library, "In this way, although everyone can't like to read, I believe that there will always be one or two who can understand the benefits of reading." ”

The Great Elder touched his beard and looked at all this with a smile, nodded in agreement, "That's right, I think so too. ”

The time that Dong Chen came here did bring a lot of changes to the Giant Stone Tribe.

It started with a change in food.

With the existence of Dong Chen, a native of the earth, it is absolutely impossible to be sloppy in eating, so that the table of the Giant Stone Tribe has undergone very rich changes, and Uncle Grill has learned more ways to make food.

And then it was this technological upgrade that made the whole tribe run and had a different atmosphere.

Originally, Dong Chen felt that the method of animal power grinding was a little slow, and it was also a little time-consuming and laborious, and when he was planning to build a wind mill or a water 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 windmill-like device on it.

"Great Elder, since there is such a device, why not use it? Isn't that more advanced and less effortless? ”

Dong Chen was a little puzzled.

"It's very advanced, but it's not suitable for us, if our Boulder tribe is a town, I will definitely use it, but we are only a tribe."

"If they don't work, they'll soon become lazy."
