Future library

For two consecutive days, Cheng Jinzhou selected three books, read 45,000 words, and used up more than a hundred stones of grain. As a result, not only did he find no refreshing chemical application books, but also basic application books. There are no similar ones. The most outrageous thing is that there is also a book using earthworm writing from an unknown country.

"If we keep doing this, we will go bankrupt." Cheng Jinzhou would say this every time he finished reading a book, but after copying it, he would buy it again.

It would be silly not to use the greatest advantage of a time traveler. Although what he is doing now is not smart.

The small accountants were more comfortable than him. They could take a day off by copying for three or four hours every day. The work is much easier than usual. It's just that the content copied is vague and I can't make mistakes, but that's it.

If nothing disturbs him, Cheng Jinzhou might look for money again in exchange for food, and then continue reading until he can't get any money, or he won't stop until he finds a book on steelmaking, ironmaking, and glassmaking. As for how to use the resources at hand, he I really didn’t have time to think about it.

Travelers prefer to save the country through industry, or make money through industry. Theoretical mathematics and English literature are too far away from the real world - at least in Cheng Jinzhou's view.

However, before Cheng Jinzhou really went bankrupt, the day of ancestor worship had arrived.

Worshiping ancestors is a big deal, especially for women at home.

The night before, Cheng's mother dug out all the things she had prepared countless days ago and rechecked them one by one. For fear of omissions, Cheng Jinzhou was inevitably taken out and tried on three sets of clothes.

The three sets of clothes are all made of Nanhu silk and satin. The two green and red long tasseled gowns are worn when worshiping ancestors. A brand new sapphire blue short shirt must be put on after the ceremony, even the gold stuffed in the neck. Suo'er has prepared two sets - a gentleman's jade. According to the Cheng family's rules, minors can only wear gold and silver.

The gown worn when worshiping ancestors is the most complicated. It has three layers inside and outside. The material is very soft and comfortable. However, after being wrapped three or four times, the tight and hot feeling is replaced by a smooth touch. It seems like I applied too much toner or cleanser.

Cheng Jinzhou twisted his body vigorously, and while fighting against the two girls, he said dissatisfied: "Mom, worshiping ancestors only lasts half a day, it's good to have one coat, why bother to make another one, and it can't be worn on weekdays?" .”

Since time travel, he no longer has any psychological burden when it comes to addressing people.

Cheng's mother looked her son up and down, and tugged with her hands from time to time, and said casually: "What if you tear it or hang it to pieces? The more times like this, the more you can't make mistakes, the whole family, and How many people are watching the visiting guests?”

Cheng Jinzhou said with the expression he inherited from the sickly man Cheng: "This dress is quite expensive, and it is not allowed to be worn except for ancestor worship. I will definitely be smaller next year."

"Oh, you have learned to be thrifty." Cheng's mother praised him first, and then said: "You can't save money that should be spent. This year, you are the only legitimate son in our family, so we must be safe."

Cheng Jinzhou was stunned and couldn't help shaking his head and laughing. A Nanhu long coat, not counting handiwork, costs at least 20 taels of silver. Two pieces cost 40 taels of silver just to wear it for a morning. This cost is not low at all. If calculated based on grain prices, it would cost at least 1,200 US dollars. If converted to the output value of modern land, it would have to be multiplied three or four times. The cost is comparable to what 21st century stars spend on Oscars shows.

The most important thing is that this is the cost of one of his children. The Cheng family is a large family, with four branches. There are dozens or hundreds of legitimate children and grandchildren in each family. The whole family only has clothes and accessories. With one item, half of the town's tax revenue can be used up.

After thinking about it, Cheng Jinzhou soon became happy again and said, "Then I will be the first one to pull out the flowers?"

The so-called "Ba Qing" means the blessing of the ancestors, which is somewhat similar to "Zhao Zhou". After the ancestor worship is over, some of the gifts given by the guests are selected and the children are asked to choose one. The difference is that children participating in the competition must be between 8 and 15 years old. They have reached the age where they can distinguish good from bad. At the same time, the gifts received by the competition do not need to be returned.

However, the birth of a child is also the beginning of children's deepest contact with this strict hierarchical society - different children enter different rooms, and the order is always based on the legitimate concubine, age and academic performance. Only the legitimate daughter Children are eligible to participate in the clan competition, and for the rest, each household must organize it themselves.

Different family backgrounds and status will naturally receive completely different gifts.

Thinking that he could pick something he liked among the gifts given by countless guests, like a free gift from a supermarket, Cheng Jinzhou almost forgot about the tightness caused by the long gown. At the very least, what he got in exchange for it would make him feel comfortable. Escape from bankruptcy.

Cheng's mother chuckled and nodded, and said, "I don't know who the old lady will favor this year. You should also review your lessons carefully so that you don't fail to answer the questions when the time comes."

When the Zhang family worships their ancestors, like most aristocratic families, they invite relatives and friends to come and watch the ceremony. Not to mention their own family, Cheng Jinzhou's five uncles, except for a few from other provinces, must attend on time and have their duties. All members of the family have to ask for leave.

Logically speaking, in the absence of Erfang, Cheng Jinzhou, as the only direct grandson of the Qingzi branch, and the largest branch of the Cheng family, must have been the first to enter the room. In fact, in the memory of Cheng Yangzi, Here, in previous years, he and his brother Cheng Jinye would enter the room alternately. But Cheng's mother couldn't speak too slowly. At least, there were two girls standing next to her.

Cheng Jinzhou also smiled and stopped talking. He was immersed in the longing for Ba Qing, imagining that he would find a gift worth thousands of gold, so that all problems about money would no longer be a problem.

Of course, this is completely his fantasy. Baqing's gifts are also carefully selected. The ones listed in the room must not only determine the value, but also have a lot of details. It is not just about putting all the guests' gifts in. You want to check them. Leakage is almost impossible.

…

In the evening, as usual, I read a book.

Although the conclusions obtained by Euclid in "Elements of Geometry" are not much different from those of junior high school geometry, the main value of Euclid's Elements - at least the current value, is mainly reflected in the process of reaching the conclusion. The taste becomes stronger when you sip it.

There are probably more mathematicians who have become famous by studying the Elements of Geometry than by studying the theory of relativity.

Cheng Jinzhou did not expect to relive the journey of his predecessors, but he tried to find traces of the Star Warlock through the few books at home - as an old boy who had received nearly 20 years of education, Cheng Jinzhou did not think that he still had The opportunity to change your mindset, in this case, is to adapt to the world.

The longer he came to this world, the stronger Cheng Jinzhou's sense of reality became. If he was still lucky at first and hoped that it would be a dream, after a month, he had completely assumed his new identity.

After time travel, people's psychology will also become different. Just like looking back at the world, new understandings, new identities, and new environments always inspire people to move forward.

Cheng Jinzhou had a deep sense of crisis.

Here, it is no longer the peaceful and peaceful world that I am familiar with.

Being born into an aristocratic family is a blessing, but competition for favor and profit is common. Cheng Jinzhou has never missed the family planning policy so much.

Whenever he thought of the sorrow of his marginalized relatives, he couldn't help but feel motivated to move forward. Originally, he was still a little unable to find his direction, but after having the Astral Library, this was no longer a problem at all.

Turning over "Elements of Geometry", Cheng Jinzhou tried his best to recall every bit of the classroom experience. In this era, even a little bit may bring about great changes.
