Zhang Zhi immediately asked Xinglan to send the company's technology and the world's public technology to his quantum mobile phone.

In this universe, he is the only one who has a science library. He can collect all the technology in the world and exchange it with the Science Library.

After consulting the system, he learned that the rating of technology needed a more advanced intelligent system rating.

The system will only be activated when you apply for an exchange technology.

Zhang Zhi turned on the membership card function and uploaded all the technologies stored on the quantum phone to the Science and Technology Library.

Zhang Zhi waited for the result, and he had little hope for it.

Earth's current technology is too low-level, and he doesn't expect to be able to exchange even the lowest-level technology.

He clicked on the information of the trading system, and the science and technology level of the science and technology library was divided into five levels.

From high to bottom, there are cutting-edge technology, excellent technology, ordinary technology, inferior technology, and junk technology.

The rating of technology is mainly based on the current use and future potential.

Just like nuclear fusion technology and quantum technology, they all have technology within the five levels of technology.

For example, the magnetic confinement fusion reaction method of nuclear fusion technology, which Zhang Zhi handed over to the country, belongs to junk technology.

And artificial star technology, which is also nuclear fusion technology, belongs to cutting-edge technology.

Zhang Zhi waited until the intelligent system rating of the science and technology library was completed.

The system said in a cold tone: "Sir, please don't be mischievous, most of the technologies you upload are invalid technologies and have no inclusion value. If you are new to science and technology libraries, you cannot accurately rate science and technology. Please use the following criteria for technology ratings. ”

Zhang Zhi wrote down the grading criteria of the science and technology library, and then he could grade it himself before handing it over to the science and technology library.

The tone of the system changed, and he said in a soft female voice: "Sir, congratulations, the technology you submitted, three inferior technology, and three garbage technology." Thank you for your support of the Science Library. ”

Zhang Zhi was stunned, there were three inferior technologies, and he thought that it would be good to have one garbage technology.

He immediately checked to see what kind of technology they were.

Inferior technology. Intelligent life manufacturing methods, plant programming design, improved broadcast gymnastics.

Junk tech. Simulated robot, black radish DNA sequence, dodder seed DNA sequence.

Li Lingqiu is really his own lucky star, and Zhang Zhi found that these technologies are all related to Li Lingqiu.

After the rating was completed, the voice of the system sounded: "Hello Dear Sir, you now have two ways to deal with your technology. ”

"You can choose to exchange the equivalent technology, or you can put it in the science library and sell it publicly. We charge a 20% processing fee. ”

"To get the most value out of you, we recommend that you do the Swap Tech Deal. ”

Zhang Zhi's eyes lit up when he heard this, and he was able to put it in the library and sell it, and the money he got was more than the money rewarded by the event.

The membership card only has instructions for changing technology, and does not tell him that it can still be sold in the science and technology library.

He immediately explained the question and the system.

The system explained: "Sir, in addition to cutting-edge technology, the technology sold in the science and technology library has archives from mainstream scientific research institutions. Transactions are subject to heavy taxes. ”

"No one wants to exchange the technology they have worked so hard to develop for the technology they can get for free in their own unit. ”

"Our science and technology library sells technology mainly for ordinary people, and the science and technology exchange system is mainly for scientific research units. ”

Zhang Zhi understood that if he were a scientist in his own plane, he would definitely choose to exchange technology.

But he is an earthling, and only by selling technology can he get the most profit. He doesn't have free technology. It can only be obtained from here.

He immediately chose to sell his technology in the library, and the exchange could only be exchanged for six copies, and it was possible that he would not use it.

After buying it, as long as there is a technology hit. And he developed.

Zhang Zhi immediately discovered that there were six more books in the library. In the future, as long as someone buys a book, he can get 80% of the coin reward.

Junk Tech is priced at $0.1 to $10. The price of inferior technology is 100 yuan to 10,000 yuan. The price of ordinary technology is 10,000 yuan to 1 million yuan.

Each of the best technologies is tens of millions to billions of dollars. Cutting-edge technology is not something that money can buy, but rare items such as resource stars to exchange.

Zhang Zhi immediately checked his technology pricing, and he was puzzled how those two plants could be rated as junk technology. The hydrogen batteries developed by Sun Qian are considered ineffective technologies.

Zhang Zhi opened it for a brief introduction to technology.

Black radish DNA sequence, Effect: Remove radioactive contamination and transform the Life Star plant. Worth $5.

Cuscuta DNA sequence, effect: absorbs other harmful gases, releases oxygen, and transforms life star plants. It is possible to convert the non-oxygen atmosphere into an oxygen atmosphere. Worth $10.

It turned out to be a plant that transformed the planet, which could transform other planets into life stars if conditions permitted. This kind of feature is totally worth it to be rated as junk tech.

For other technologies, Zhang Zhi knows what it is used for, and only looks at its price.

Improved broadcast gymnastics, worth 500 yuan.

Plant programming design, 5000 yuan.

Zhang Zhi still remembers that this technology was bought by him in order to curry favor with Li Lingqiu, when he was still very poor, and bought it for 1 cent.

After Li Lingqiu's improvement, its value turned out to be so high. It's a real book.

He saw the last technology, intelligent life manufacturing technology 10,000 yuan.

Zhang Zhi's saliva was left, it was so expensive, reaching the limit of inferior technology. Intelligent life is much more valuable than he thought.

His choice was right, as long as this technology was sold, Zhang Zhi could buy tens of thousands of junk technologies.

The most rubbish technology here, when it is taken to the earth, is a proper high-tech.

Zhang Zhi couldn't sleep excitedly, he was waiting for someone to buy his own technology.

As you can tell from the name and price, junk and shoddy technology. In addition to having characteristics, it is almost difficult to earn money.

He's trying to sell these three junk technologies. The price of intelligent life manufacturing technology is more than 10,000 yuan, and it belongs to the cheapest intelligent life manufacturing technology. Someone should buy it.

After waiting for a long time, no one bought it, and Zhang Zhi felt that the price of the science and technology gallery was set high, and the price was 100 yuan. The technology is too expensive for no one to buy.

"Hello sir, your inferior technique has been sold and recorded for 4,000 yuan. ”

Zhang Zhi jumped up happily in the library, and then frowned. It should be 8,000 yuan, how can it only be 4,000 yuan.

Zhang Zhi immediately consulted the system, and he wanted to find out the situation.

"Hello sir, since you made an anonymous sale, you do not enjoy the tax deduction of the state for citizens. According to the most important way of taxation, the tax is 50%. ”

Zhang Zhi shook his head helplessly, he was a black household, and it was normal for him to be heavily taxed.

He saw a huge sum of 4,000 yuan in the account, which was a huge amount of money that he had never seen before. Finally, I don't have to spend money to buy whatever I want.

With a wave of his hand, Zhang Zhi directly bought a copy of the science and technology tree details of the stellar system civilization in the science and technology library.

It doesn't have a specific technology, but it can point the way forward for scientific research. It is most suitable for use in scientific research platforms.

It's not expensive, it's only 4,000 yuan. Zhang Zhi finally experienced the feeling of a local tyrant in the science and technology library.

He remembered that there was a lottery on the membership card, but now he doesn't care about it, and just plays it for fun.

He drew the Bubble Mouse and is a pet endemic to the planet M302.

Zhang Zhi's heart did not fluctuate, and the lottery was all cheating people.
