"Coo", Lord Stomach protested against Liu Yun, a person who doesn't pay attention to eating, and it's been five or six hours since he came out in the morning and even ran and talked, and he didn't know where to go for a few fritters in the morning. Pen ~ fun ~ pavilion www.biquge.info

Feeling the less than a hundred yuan left in his pocket, Liu Yun's mood calmed down a little. "Hey, as a hero who is destined to save the world, it's really pitiful that he still has to worry about worldly money. "Someone's secondary two illness is committed again, and he complains in his heart. But the current situation is like this, the Universal Knowledge Card does not allow people to travel freely through the various worlds, there are countless people in this universe who have this thing, but 99% of people still live in their own worlds and have not achieved remarkable achievements.

Liu Yun is no exception, he is just a little lucky, leading all the earthlings to successfully bind the first universal knowledge card. He is still a high school student, he doesn't have much life experience, and even with the Universal Knowledge Card, he doesn't know how to use this thing to get real benefits for himself. In the final analysis, the World Wide Web only provides a platform for people to communicate freely, and how to use this thing for their own benefit depends on the ability of the individual.

There are indeed many items in the Wanjie Mall that are ahead of the earth's technological level, but it is still very difficult to make them appear on the earth less disobediently, so that everyone thinks that the appearance of this thing is not so unbelievable. Liu Yun didn't think that he could buy all kinds of medicines, scientific and technological drawings or anything that could be taken out directly, whether it was handed over to relevant state agencies or doing some research by himself. You must know that a country's scientific research strength is very strong, so strong that it is difficult for any individual institution to surpass, if Liu Yun, as a high school student, came up with a scientific and technological product beyond this era, the country does not mind taking him, a little person who is nothing, away to drink tea or something.

Now Liu Yun's difficulty is how to gradually improve himself, his wealth, and his influence without attracting special attention from others. The first thing that comes to mind is all kinds of advanced alien technology, but Liu Yun's current living standard is not enough to support the consequences of his exposure of alien technology, so he can only secretly buy a little for his own use.

First of all, we have to determine the general direction, clothing, food, housing and transportation, is the basic component of people's lives, if you do business to make money, you must consider the audience, the size of the consumer group for a person's business, directly determines what scale the person's business can eventually reach. Clothing, housing and transportation all require a certain starting point, but also require professional knowledge, Liu Yun does not have that aspect of the conditions at present, can only start from the aspect of eating, as the first stage of his own start. But Liu Yun understands in his heart that the catering industry is easy to get started, but if you want to rely on this to make a lot of money, it is not ordinary. For example, Liu Yun once read a novel that said that a person can earn millions a day by relying on dozens of ramen shops, or nearly a billion a year. Liu Yun scoffed at this, even if it is a novel, please use your brain, if you have a net income of 1 billion a year from 20 ramen shops, how can you make those Internet giants such as NetEase and Shengda embarrassed? How much money can you make in a year by looking at other people's financial statements?

After thinking about it, Liu Yun still gave up his plan to start from catering, first, he had no start-up capital, second, he had no experience in business, even if he could borrow money as initial capital, he did not guarantee that he would be able to make money. It is still necessary to start from the aspect of science and technology, some simple, not many advanced earth science and technology products and computer technology of the eighth and ninth level civilizations can still be used, Liu Yun plans to start with the network technology first.

In fact, the distance between the earth and the ninth-level civilization is not too far, and the evaluation standard of the ninth-level civilization is that the human beings on the planet have the ability to travel interstellar, and they can use the interstellar spacecraft produced by their own planet to reach the galaxy to which they belong for space exploration. According to Liu Yun's understanding, now human beings on the earth can leave the earth and stay in outer space for a short time, which is not far from interstellar navigation, but if it develops normally, it may take decades or even hundreds of years. Some ninth-level scientific and technological civilizations are still using computers similar to those on the earth, but they are more powerful and have stronger processing power, and Liu Yun's current plan is to improve the level of computers on the earth a little first, and strive to reach the level of ninth-level civilization.

Thinking of this, Liu Yun entered the Wanjie Mall to see if there was any network technology suitable for him to use now.

After a period of browsing and watching, computer blind Liu Yun realized that determining the computer level of a scientific and technological civilization depends on both hardware and software. If you want your computer to be more powerful, you first have to have better software at the current level, and second, you have to have hardware that can support more powerful software. With the current computers on the earth, the use of hardware is far from reaching the limit, so Liu Yun can first buy a software that can run on an existing computer to earn some living expenses for himself.

[Basic knowledge of computer network of the ninth-level civilization: all the basic network technologies of the ninth-level civilization are recorded, and the network technology level of a civilization can be understood in detail, price: 20. Note: There is no physical product for this product, and all contents can be viewed in the personal center after purchase. 】

Liu Yun himself is not proficient in the computer network, so he can only make up the basic knowledge first, and see where the gap between the earth and the ninth-level civilization is, so that he can operate his plan.

The current network technology is actually very developed, and after only twenty or thirty years of development, it is enough to support the basic interstellar voyage for a long time, which is rare in other scientific and technological civilizations. When Liu Yun browsed the network technology of the ninth-level civilization in the Wanjie Mall, he found that it was really only nearly a hundred years or even decades ahead of the earth, because Liu Yun did not know what the most developed network technology on the earth was now, and he could only judge by what he could access now.

[Cloud Shield: Clarke, a ninth-level civilization, is a network security software of cloud companies, integrating anti-virus and defense, which can resist the attacks of most hackers in the ninth-level civilization, and is even well-known in the eighth-level civilization, and has relatively low hardware requirements. Price: 50. Note: After purchase, the software program code can be viewed in the personal center. 】

It's also difficult to make money with software, because there are too many people in the world who make a living from this, and if you want to stand out from countless software, you need certain means. Security software is relatively easy to accept, as long as the security is good, can surpass other similar types of software, naturally some people will use it, because this kind of software for people to use the inertia is very small, unlike chat software or something, a person is used to it and will rarely change to new software after use.

That's you.
