Cheng's mother's housekeeper can be regarded as fine, and she is even more willing to her son, but it is a pity that Cheng Jinzhou's ring is a bottomless pit, how many resources, and there is no saying that it is full, and there are 5o more stone of grain per month, which can only be said to be better than nothing.

5o stone is equivalent to an extra 1o taels of silver per month, and you can read more than 10,000 words, the size of a few pages of a book.

But for farmers, in this era, 5o stone requires at least 15 acres of sloping land for a year's labor, which is equivalent to the output of 8 acres of flat land, and it is also a lot of money in the homes of ordinary rich families.

Numbers are a cruel thing, and it takes a few seconds to calculate the answer, and Cheng Jinzhou has no other expression except a wry smile.

In the next few days, Cheng Jinzhou returned to the state of reading in class, and the gold rewarded by Cheng's mother could be exchanged for 4oo taels of silver, saving some flowers, which was still a lot of money. It's just that I bought two books in a row, and I didn't come across anything valuable.

Although it was all very nutritious content, Cheng Jinzhou still went to another courtyard and asked the bookkeepers to transcribe it and hide it in the room to see if it could be used in the future.

The most troublesome thing is naturally Cheng's father's school homework. The prefect is not a pedantic person, seeing that his son has an advantage in mathematics and science, he will also focus on the basics, but Cheng Jinzhou's knowledge is the foundation of the foundation, and some fatigue is inevitable.

As with many new technologies, the reason why the hard pen was not favored in China at the beginning was also related to the high skill of the old gentlemen, a good calligrapher, using brush characters, can write faster and better than a fountain pen - although the former requires more effort, but you can't find enough reason to obsolete, until the 70s of the 2o century, China was still producing a large number of soft pens with brush-like tips. Of course, the application of new technologies deserves this conservative test, and in fact there are far more eliminators than those who pass it, although the elimination is not necessarily successful.

After about a week like this, Cheng Jinzhou couldn't stand it anymore, and every day Mengmeng went to the private school, accepted the poison of the gentlemen, and waited until the afternoon, from time to time to have cordial and friendly meetings with relatives who were looking for curiosity, and then read by himself in the evening - the sky is pitiful, when Cheng Jinzhou was taking the doctoral examination, he was not so hard.

For the lazy Cheng Jinzhou, he cannot be required to have a firm, brave, and positive heart. Of course, he wants to move up, he's positive, but he hates hard work even more. As a new generation of youth, his expression is very reasonable.

By the time the food arrived in the middle of the month, Cheng Jinzhou had already accumulated strong resentment, and when he got a book of "Improving Ancient Portuguese Grammar" again, Mr. Customer Service finally said in a stylized tone: "Congratulations, the level of the Star Alliance has been increased to 1o points, and it is currently level 2." ”

Cheng Jinzhou's resentment suddenly couldn't be suppressed anymore. He almost gritted his teeth and pointed at the wrench: "In this case, will you not give me this kind of garbage again in the future?" And the terminal, how many books can be kept? ”

The customer service o1o was unmoved and surfaced from the ring face, revealing his avatar and said: "The terminal can keep 2 books, about the book category, you can buy the "Star Alliance Library Redemption Huàn Table", and choose the book you like." ”

Cheng Jinzhou snorted twice, took out the spirit of cheating in the examination room, and said seriously: "I definitely can't afford this exchange table, but in exchange, the same cost does not increase your burden, so why give me something I can't use?" ”

"We have the authority to prescribe."

"Then now that the level of the Star Covenant has increased by one level, shouldn't I have the right to choose?" Cheng Jinzhou knew that it was not so simple, but he still tried hard: "If you want to have something you like, you can also ask for it from me, how can you say that I am also your only supplier here, right?" Is it the planet or what extent? ”

The customer service snorted twice and said, "Question about the price of materials......

"I know, I know, you still have a supply sheet, don't you?" Cheng Jinzhou smiled and said: "But let me spend money on this, it's not in your best interest, what do you like, say it, I can find it, here, I still have some ability." I am tired of just selling grain, and you are also tired. ”

Mr. Customer Service paused for a moment and said, "The identification of the materials in your area requires a certain amount of resources, and it is meaningless until you are unable to pay." ”

Cheng Jinzhou's teeth itched with hatred, and he still said with good words: "The opening of a fresh area always has to be invested, isn't it?" If you want to accumulate on your own, how long will it take for your civilization? If I show it fast, you know that the resources I get are not more than to say, the Star Alliance is a civilization, right? ”

He also wanted to spy on some information by the way.

It's just a conversation between the two of them, and the customer service o1o didn't think too much, and said quickly: "The Star Alliance is a trading alliance of civilizations, and at present, with your Star Alliance level, dividing the book category is already the biggest authority." ”

"Then either you translate it, or give me not only the Chinese version, but also the English one." Cheng Jinzhou is also helpless, really to say that the book that can be used, before the 6th century AD in Greek, then Arabic, then Latin, the 2o century to German industrial research is the most advanced, the 21st century is naturally English, really speaking, you can use it, maybe Latin is more reliable, English and German are also reluctantly, the coverage of Chinese is still too small, at least in the academic world, there is no influence, no matter how big Chinese scholars, can not learn English, But the back of the ass has to keep up with two or three graduate students who are English thieves in order to get mixed up.

Mr. Customer Service said quite rigidly: "Your Star Alliance level is insufficient. ”

Cheng Jinzhou had already begun to scold his mother in his heart, and his face was still full of enthusiasm: "This is a good thing for you, I am good, everyone is good, you see, with the help of the Star Alliance, my exhibition will definitely be very fast, and the more help you have, the more I will return, now I am not unwilling to pay, I just want to make myself more choices, so that the cost of choosing is lower, but your more profitable products, you give me more useful technology at the same cost, isn't it?" ”

Customer service O1O was silent for a moment and said, "The adjustment of the book category requires permission. ”

"Oh, lo and behold, listen to you, I know you have this power, poerfu1, right?"

A long list of compliments may really have some effect, and the customer service comrade was silent for a moment, and said: "Out of support for the low-level astral boundary, you can choose to translate some books at a price, and the price is 5o% of the selling price." ”

"What about the others?"

"There are no other offers." The customer service comrade returned to a dry tone

Cheng Jinzhou exhaled heavily in his heart, at least he could bear it.
