The real world has realistic laws.

For the younger generations of the Cheng family, there are two ways to go. One is to take the imperial examination and become respected civil servants. If you want to be more noble, you can also try to enter the temple to be a pastor. The Cheng family is very prestigious locally, and most of the children in the family take this path.

As for the second one, it is to become awesome astrology warlock, just like the little flying people Cheng Jinzhou saw before. It’s just that this road requires more talent and more good luck.

The future of astral warlock is largely determined by the star array. Although in theory, everyone can carve countless star arrays, in fact, the star array will bring huge burdens to the human body. The more advanced the star array is, the more so. To use the star array well, the more complete knowledge and intelligence is needed. The star array commonly used by the general public has never been the choice of the children of aristocratic families.

As for Cheng Jinzhou, he didn't want to take either of these two paths.

He had long been very tired of studying similar to the imperial examinations. As for astrology, he had to learn several times more. Fortunately, he was still young and had enough time to squander.

Occasionally, Cheng Jinzhou would hesitate. He finally traveled through time once, and seemed to have done something thrilling, so he could not do anything in history, but when he really wanted to do something, he was so irresistible that he couldn't start.

"Ring..." Cheng Jinzhou sighed a long time ago, lay on his bed, rubbed his fingertips, and said to himself: "Speak out what you want, money or beautiful rings, how good we can get each of us, although the playboy is also good."

As he spoke, his eyes floated up to the playboy. When he came to this world, although the maids looked fair and honest, they were still not as beautiful as the models of later PS, not to mention that they had completely different exposure levels.

"Star Covenant Library No. 010 is here to serve you, what do you need?" A heavy male voice suddenly came from the ring.

Cheng Jinzhou's first reaction was to look back, then quickly covered the ring, blinked his eyes twice, and said, "What did you say?"

"This is customer service No. 010 of Star Covenant Library. I heard you are willing to pay to read a book?"

"That's right, right." Cheng Jinzhou's head was about to break, and his eyes were fixed on the ring.

Customer Service 010 said in a boring tone: "The charging standard is 2 yuan per thousand words, there is no public version, you must subscribe all, no discounts, no activities."

"2 yuan? What currency unit?" Cheng Jinzhou was very sensitive to numbers and banknotes.

"2 star yuan, but we charge various currencies according to your regional standards..." The customer service delayed for a moment and said: "You can only pay physical currency. There are two main forms. In terms of energy, one yuan is 0.25 tons of standard coal equivalent. You can also pay with wood, oil or natural gas. Of course, if there is direct energy such as electricity, there is no problem. In addition, you can also pay with edible resources. One yuan is equivalent to 0.1 tons of grain, or half of meat, specific exchange methods for other elements and valuable materials. You can purchase the Star Covenant Library Exchange Form to query, with a total of 6,000 thousand words and a price of 12,000 yuan. You must subscribe all."

Cheng Jinzhou was not concerned about the so-called standard coal and other content, but quickly calculated the numbers and said: "All subscriptions are 12,000 yuan, which costs 3,000 tons of coal or 1,200 tons of grain?" He said: "It's too expensive. How can I pay you?"

No matter what, Cheng Jinzhou will not give up such an opportunity. Price issues are nothing in front of the magic in front of him. You can talk about the redemption form later, but it is true that you must hold this customer service back.

"After starting the payment program, the user terminal can be used as a medium." As if worried that Cheng Jinzhou would not understand, the customer service added: "Your user terminal is this ring."

If Cheng Jinzhou hadn't traveled through time, he would have had a headache for these nouns. At this moment, of course, he just asked excitedly: "What about silver and copper, how do you calculate it?"

Customer Service 010 hesitated and said, "These two finally tell you for free. The price comparison of silver is about 50 grams per yuan, and copper is 100 yuan per ton."

No need to count, it is definitely not cost-effective to use money as materials. Cheng Jinzhou immediately asked again: "Who are you? I mean Xing Coalition and the library."

He naturally had many questions, and the customer service was prepared and said in a formula: "For the introduction content other than transaction payment, we charge an information fee of 20 yuan per minute. Please pay first."

"It's not **." Cheng Jinzhou said as he missed it, and then said, "What's the playboy in front?"

“Trial version.”

"The trial version is indeed a good-looking but useless thing." Cheng Jinzhou shrugged, "Then let me make a book about glass. Do you have any suggestions?"

"You can buy "Star Covenant Library Book List" to query, with a total of 85 million words, and the price is..."

This price is absolutely unaffordable. Cheng Jinzhou quickly interrupted him and said, "I understand, but you always have to give me a title."

"If you don't buy the "Star Covenant Library Book List", you can only choose random books." Customer Service 010 said bluntly.

"I know the name, either?" Cheng Jinzhou whispered.

"This requires you to increase your Covenant level..."

Cheng Jinzhou immediately asked: "What is the Star Alliance level?"

“About transactions…”

"I understand." Cheng Jinzhou tried hard to finish his last effort: "Then you have to give me a range. I can't want chemical engineering. Please give me literary and publishing years. How many years have the Star Coalition developed there?"

He still missed in searching for news.

Customer Service 010 paused for a moment and said: "Given that you are the only user in the region, you can choose the major category of books - the star field content."

Cheng Jinzhou, regardless of what the other party called the major category, said first: "If you want basic application, you can use it in my era, and in addition, it is cheaper."

Customer Service 010 may not be too lazy to object, and said directly: "I have randomly reached a book with a qualified number of words, with 3.6,000 words, please pay 7.2 yuan."

"What's the name?"

"Please pay 7.2 yuan." Customer service 010 said unmoved.

Cheng Jinzhou had no choice but to give up such a good opportunity and said, "When will I pay, I will have books to read, right?"

"That's right." Customer service 010 said nothing and even the playboy in the void was put away. It was obviously the trial period, but it was shorter than the activities in the unscrupulous mall.

Cheng Jinzhou never knew that he had such a yearning for knowledge. Even the disappearance of the Playboy was just a regret - although the beauties were good, they were everywhere, but the Star Realm Library was unique to this world.

Before traveling through time, the sick son Cheng saved dozens of taels of silver in private money. With his body, it was not easy to spend it. At this moment, Dr. Cheng was all cheaper.

Dr. Cheng didn't take out all of them. He counted two ingots of silver, took a few more silver slots, put the rest in place, and then walked out of the house.

There were always maids waiting outside the door, and immediately bowed to say hello. Cheng Jinzhou waved his hand and said, "Liu'er, do you know how much the food price outside is?"

Although he was strange about the little master's problem, Liu'er still saluted properly and said: "Brown rice is 400 meters per stone, and wheat is about 350 meters."

The so-called brown rice is rice that retains part of the outer layer after the rice is unhulled, which is quite different from the refined rice in the 21st century. Cheng Jinzhou didn’t know if it was suitable for trading, so he asked again: “What about the coal price and dry firewood?”

"The smoke from coal is too big, so there is no need for the family." Liu'er looked at Cheng Jinzhou carefully. He didn't know when his master would take care of these things. He even said, "I think the firewood is good or bad, and a load is twenty or thirty cents."

Cheng Jinzhou responded and silently walked out.

It is the most unprofitable to exchange silver for star dollars, and the other party does not regard this as currency.

There is no need to consider coal. With the technology of this era, the cost is not low and the quality depends on the place of origin. It is definitely not cost-effective to buy less. As far as he knows, coal with more smoke will produce less heat.

As for grain, one stone is about 50 kilograms, and 20 kilograms is only one ton. In other words, a ton of brown rice costs 8,000 yuan. Although the money is cheap and the silver is expensive, it is still indispensable for 4 taels of silver.

4 taels of silver exchanged for 10 stars, Cheng Jinzhou didn’t know whether he should be happy or worried about the purchasing power of the silver.
