The housekeeper Cheng’s mother is very meticulous and is even more willing to give up on her son. Unfortunately, Cheng Jinzhou’s ring is a bottomless pit, and there is no saying that he has enough resources. He can only say that he has 50 stones of food per month, which can only be said to be better than nothing.

50 stones are equivalent to an extra 10 taels of silver per month, which can read more than 10,000 words, just a few pages of book size.

But for farmers, in this era, 50 stones would require at least 15 mu of slope land a year, which is equivalent to the output of 8 mu of flat land. It is also a lot of money to put it in the homes of ordinary wealthy families.

Numbers are cruel things, and the answer is calculated in a few seconds. Cheng Jinzhou has no other expression except for a bitter smile.

In the next few days, Cheng Jinzhou returned to the state of reading in class. The gold rewarded by Cheng's mother could be exchanged for 400 taels of silver, saving some money, which was a big deal. But even after buying two books, he didn't encounter anything valuable.

Although it was very nutritious, Cheng Jinzhou went to the villa and asked the accountants to copy it and hide it in the room to see if it could work in the future.

The most troublesome thing is naturally Cheng's father's school exam. The prefect is not a pedantic person. Seeing that his son has advantages in mathematics and physics, he also focuses on the basics. It is just that Cheng Jinzhou's knowledge is the foundation of the foundation, and it is inevitable to work hard. Just re-recognizing words and learning to use a brush can consume all the time.

Like many new technologies that cannot be applied, the reason why hard pens are not favored in China is also related to the fact that the old gentlemen are too superb. A good calligrapher can write faster and better than a fountain pen - although the former requires more effort, you can find enough reason to eliminate it. Until the 1970s, China was still producing a large number of soft pens with pen tips like brushes. Of course, the application of new technologies should suffer this conservative test. In fact, there are far more eliminations than those who pass, although eliminations are not necessarily successful.

After about a week, Cheng Jinzhou couldn't stand it anymore. Every day, he went to a private school to receive the poison from all his gentlemen. In the afternoon, he would have to have friendly and friendly meetings with his relatives from time to time, and study by himself in the evening. He was so pitiful that Cheng Jinzhou did not have such a hard time when he was taking the doctoral exam.

For the lazy Cheng Jinzhou, he cannot be required to have a firm, brave and positive heart. Of course, he wants to be positive very much, but he hates hard work even more. As a new generation of young people, his performance is very reasonable.

When the food in the middle of the month arrived, Cheng Jinzhou had accumulated strong resentment. When he got a book called "Ancient Portuguese Grammar Improvement", the customer service finally said in a stylized tone: "Congratulations, the level of the Star Covenant has been raised to 10 points, and it is currently level 2."

Cheng Jinzhou's resentment could no longer be suppressed. He almost gritted his teeth and said to the ring, "If this happens, will you not give me such garbage in the future? And the terminal, how many books can you keep?"

Customer service 010 unmoved to float out of the ring face, revealing its avatar and said: "The terminal can keep 2 books. Regarding book categories, you can buy the "Star Covenant Library Redemption Form" and choose the book you like."

Cheng Jinzhou whispered twice, took out his energy to cheat in the exam room and said seriously: "I definitely can't afford this exchange form, but in exchange, the same cost does not increase your burden, so why should I give me something I can't use?"

“We have the authority to stipulate.”

"Then I have increased my level of the Star Covenant by one level, so shouldn't I have the right to choose?" Cheng Jinzhou said hard, even though he knew it was not that simple: "You should have something you like, you can also ask for it from me. How can I say that I am the only supplier here, right? Is it this planet or what range?"

The customer service hummed twice and said, "About the price of materials..."

"I know, I know, you have a supply list, right?" Cheng Jinzhou smiled and said with a laugh: "But letting me spend money on this is not in your best interest. What do you like to ask for? I can go find it if you say it out. I still have some ability here. I am tired just by selling food, and you are also tired."

The customer service paused and said, "The identification of materials in your area requires a certain amount of resources. It is meaningless until you are unable to pay."

Cheng Jinzhou was so angry that he still said kindly: "The development of a fresh area always requires investment? Isn't it? If you have to rely on self-accumulation, how long has your civilization been used? If I develop quickly, you know that the resources you get are not more. Star Covenant is a civilization, right?"

He also wanted to spy on some information.

Just a conversation between two people, customer service 010 didn't think too much and said quickly: "Star Covenant is a trading alliance of civilizations. At present, based on your Star Covenant level, it is already the greatest authority to divide the major categories of books."

"Then you can translate it, not only give me the Chinese version, but also the English ones can be barely enough." Cheng Jinzhou was also helpless. Before the 6th century AD, most of the books were Greek, followed by Arabic, and then Latin. In the 20th century, German industrial research was the most advanced, and in the 21st century, it was naturally English. In fact, it was really possible to use it. Perhaps Latin was more reliable, and in English, German, and the coverage of Chinese was still too small. At least in the academic world, there was no influence. No matter how famous Chinese scholars were, they could not learn English, but they had to keep up with two or three good graduate students in English to make a fortune.

The customer service man said quite rigidly: "Your Covenant level is insufficient."

Cheng Jinzhou had already started cursing in his heart, and said enthusiastically: "This is a good thing for you and I, everyone. Look, with the help of Star Couplet, my development will definitely be fast, and the more you help you, the more rewards I will also be. Now I am not unwilling to pay. I just want to make more choices and make the choices lower cost. But if you have higher profits, you will give me more useful technology when the cost remains unchanged, right?"

Customer service 010 was silent for a moment and said: "The adjustment of books major categories requires permission."

"Oh, look, I know you have this power, right?"

A long list of compliments may have really had some effect. The customer service comrade was silent for a moment and said, "For the support of the low-level astrology, you can choose to translate some books at a cost, at a price of 50% of the price."

“What about the others?”

"No other offer." The customer service comrade returned to his dry tone.

Cheng Jinzhou let out a heavy breath in his heart, at least it could bear it.
