Luohongyuan is located in the hinterland of the wild continent, because there is the eternal rushing flow of the Longjiang River traversing the east and west, the water system network of the branches of the river washes and accumulates the fertile plain that stretches for thousands of miles, there is a pleasant climate, the wind and rain are smooth, and now it has become a place where the human race has gradually escaped ignorance.

Thousands of human tribes are scattered like stars on the vast plains, with populations ranging from tens of thousands to hundreds, some of whom have begun to skillfully engage in farming, sericulture and weaving, while others are still fishing, hunting, picking, and drinking blood.

Although after thousands of years, relying on the heroic sacrifices of countless warriors who have followed each other, they have expelled all kinds of fierce beasts and poisonous insects that were originally entrenched in the Luohong Plain, and occupied this fertile land that is most suitable for human habitation, but the human race has never been the master of this land, and the two mountains of the demon race and the demon race have always been pressed on their heads.

Since human beings have had their own language and even writing, all records show the fact that the two demon races are high above and the human race can only exist as their vassals, which makes the human beings who originally belonged to the same race have to be divided into two and belong to the demon two races.

Just like the human beings on the Luohong Plain in today's life as vassals of the demon race, not only do they need to do their best to please the demon clan with treasure women on weekdays, but whenever the demon clan and the demon clan lose harmony, the human beings on the Luohong Plain also have to recruit strong men, as the servant army of the demon clan, go to war with them, and wave weapons to the human race who belong to the demon clan and fight hard.

Strange to say, the two demon clans seem to have formed a tacit understanding, whenever the number of humans in their respective territories grows to a certain value, they can always find an excuse to start a war, and after each big battle, the two clans themselves have limited losses in warriors, but the Terran servant army always suffers heavy casualties in the fierce battles.

There are many intelligent people among the human race, and they have long guessed that this is the intention of the two races to consume the vitality of the human race, so as not to threaten the dominance of the two races with strong fertility and rapid growth.

It's just that I know that the strength of the individual Terrans is too weak compared to the two demon races, and the current number of the human race is far from enough to reverse the gap in strength between them, so they can only forbear and survive and develop year after year according to the trajectory arranged for them by the two demon races.

On this day, a teenager hurriedly walked through the crowded market where the bear roaring department in the northwest of Luohongyuan was located.

"Gongliangye, today we are going to hunt wild ducks in Heishui Lake, you should come too!"

A group of teenagers, also in their teens, walked out of an alley on the side of the road, and when they saw a teenager walking through the middle of the street, one of them immediately called out.

The young man turned his head to look, a bright smile like sunshine appeared on his handsome face, and said loudly: "I still have to go to Teacher Yu to learn things, I won't come with you today, see you another day!"

He kept talking, and when he finished speaking, he was already far away.

Another teenager in the crowd looked at the back that was about to disappear and smiled: "Gongliangye, this kid has changed his temperament, he used to be more foolish than any of us, but now he can honestly go to that Mr. Yu every day to listen to those dizzying things." ”

The young man before said with a straight face: "I once overheard the conversation between the Great Elder and Daddy, and they all said that Mr. Yu is a really capable person, and the people who teach Gongliangye are also very useful knowledge, but it's a pity that we don't have that comprehension society." However, as long as Gongliangye learns it, it will be of great benefit to the future of our bear roaring department. ”

Another teenager thought deeply and said: "If you want to say that Mr. Yu does have skills, these days I have been insisting on practicing the fist and foot kung fu he taught us, and I found that my strength is getting bigger and bigger, and my ears and eyes have become much more sensitive." ”

When the other teenagers heard this, they all said with a look of surprise on their faces: "So do you feel the same way?" I am the same, but I didn't dare to believe it at first, and I just thought it was my own delusion......

While the teenagers were talking, Gongliangye had already come to a courtyard with seven or eight rammed earth walls and a white thatched roof, and a bamboo fence outside, and first stopped and carefully put away the clothes on his body, and then stepped forward, raised his hand and lightly buttoned the door twice.

As soon as the knock sounded, the two wooden doors opened lightly inward, revealing a young woman in cloth and hairpins with a heroic face, but who was Nie Yinniang, the first disciple of Yu Tianlai's door?

"Senior sister. Gongliangye bowed to Nie Yinniang in a regular manner.

Nie Yinniang waved her hand and smiled: "You kid turned out to be a monkey-like guy, how did he be taught by the master for a while, and he turned into a little adult." Misleading people's children, nothing more than this!"

When Gong Liangye heard this senior sister so unscrupulously slander his god-like teacher, although he didn't dare to agree with it in his heart, he didn't dare to oppose it, so he had to laugh dryly, his face full of embarrassment.

"Yinniang, if you are bored, go out and walk around by yourself, don't always use your little junior brother for entertainment!"

A gentle voice came, wearing a light white robe woven of wild linen, and Yu Tianlai, who was wearing a light white robe woven of wild linen, walked out of a hut with his long hair casually, first reprimanded Nie Yinniang with a smile, and then beckoned Gong Liangye to his side, led him to a grass pavilion in the backyard and sat down, and asked with a smile: "I left you a question for the teacher yesterday, can you come up with some eyebrows?"

Gong Liangye replied respectfully but confidently: "The disciple has been thinking hard all night and has gained something, and he is about to ask the teacher for advice at this moment. The teacher said that everyone in the market is bartering when trading, firstly, the value of each other's goods is difficult to measure, and there will inevitably be many disputes during the transaction, and secondly, it may not be able to make both parties exchange for the goods they are satisfied with, which is indeed inconvenient. The disciple thought that the solution to this problem was to make a certain common commodity a common medium of exchange, by which the value of all goods should be measured, and the trader would first exchange his goods for this medium, and then use this medium to exchange the goods he needed. ”

Yu Tianlai slapped his hands and smiled: "Good boy, you really thought of it! The 'medium' you are talking about is 'currency', commonly known as 'money'. With this thing, the goods in the world can really circulate, and in the process of circulation, it will produce incalculable value. ”

Then he explained the principles and uses of money in simple terms, and then expanded from the problem of coins to many other ways to govern the world economy and the people's livelihood.

Gongliangye's eyes were brilliant when he listened, and his heart felt like he was suddenly opened.

After a while, Yu Tianlai's lecture came to an end, and as usual, he left a question for Gong Liangye to think about and answer, and then he took the test to enter the country.

Gong Liangye didn't dare to slack off, first talked about his progress in the cultivation of internal strength, and then used a bamboo branch instead of a sword, and practiced the swordsmanship taught by Yu Tianlai all the way in the courtyard.

Yu Tian came to see this kid's swordsmanship all the way, the sword moves were still taught by himself, but the sword intent evolved a little bit of his own charm, faintly there was a bit of grandeur, and at the same time, he secretly approvingly made a decision in his heart.

Just when Gongliangye's swordsmanship was finished, a laugh suddenly came from the place close by: "Haha, brother, you have done a great thing!"

Set a small goal first, such as remembering in 1 second: book guest residence
