During the days of waiting for An Qi's reply, Ren Pingsheng needed to stay in Hanhai City for a while, but there was no need for him to rent a house, because Zhang Wenwu's house was currently vacant, and Ren Pingsheng could go and have fun with his old classmates.

Mr. Zhang's father bought the house around 2002, when the price in Hanhai was only about 5,000 yuan per square meter, and the location in the Handong New District, which is still under development, may have been even lower.

In the memory of Ren Ping's previous life, the housing prices here have increased by about 6 or 7 times after ten years, so Zhang's father still has a great investment vision.

The house itself is not big, only about 100 square meters, divided into three bedrooms, one living room and two bathrooms, the shrewd father Zhang sublet the house during his son's study, and the rent can basically cover the bank loan.

Before his son graduated, Zhang's father took back 2 of the bedrooms, and only 1 tenant is still left, and the other 2 are used by Zhang Wenwu.

Although Zhang Wenwu received Ren Pingsheng very warmly, as an old classmate, Ren Pingsheng insisted on paying rent according to the market price, and he was not a person who liked to take advantage of others.

After several polite excuses, Zhang Wenwu couldn't resist Ren Pingsheng, so he had to agree to accept the rent of his classmates, but he must ask Ren Pingsheng to live for a month before giving it, otherwise he would not accept any money.

In line with the friendship of classmates for many years, the two sides reached an agreement on this basis, and Ren Pingsheng moved his little luggage into it and began this period of cohabitation.

As a newcomer, Zhang Wenwu was assigned and arranged quite complicated work, and his branch was located in the financial center of Handong New District.

Although the other tenant is not an office worker from 9 to 5 in the morning, he also goes out early and returns late most of the time, so most of the time, Ren Pingsheng stays in the house by himself.

For this lonely state, Ren Pingsheng is no stranger to it, and he does not resist. Since the four years of college, he has been accustomed to a solitary life, and even if he has Zuo Xiaoxiao later, it has not affected his work and rest routine.

Whether it is in his hometown, at his aunt's house, or at Zhang Wenwu's house, Ren Pingsheng insists on getting up early, running for one hour to the nearby park and sidewalk at 6 o'clock, and when he comes back, he buys two breakfasts for Zhang Wenwu and himself at the supermarket at the entrance of the community. After Zhang Wenwu went to work, Ren Pingsheng would spend the whole morning meditating and contemplating.

After being reincarnated, he found that his memory had improved a lot, which should be an advantage brought by his young body, but after all, there were too many memories of his previous life, and if he couldn't sort it out well, it would gradually pass with time.

For Ren Pingsheng, the memory of his previous life is his biggest capital, and it is also a necessary tool for his entrepreneurial success, so he must manage these funds well.

Although his memories are numerous and complex, Ren Pingsheng has always been reluctant to use pen and paper or computers to record, although these methods are simple and effective, but they are not safe.

No matter in the future or now, as long as there are traces of something, it may be discovered, and it may threaten Ren Pingsheng's safety and career, and he must not take this risk.

Only memories without traces are the safest.

Even before Ren Pingsheng was reincarnated, the scientific community did not have the technology to read human thoughts and memories, so Ren Pingsheng would rather spend more effort and time to sort out and consolidate his memory.

Of course, Ren Pingsheng did not choose memory whimsically. Since he was very young, he has had a memory method that others don't understand, and it is also relying on this memory method that he can accumulate so much knowledge and information, so that Zuo Xiaoxiao, one of the four beauties of Hanhai University, can be impressed by her.

It's just that in his previous life, the environment and career that Ren Pingsheng chose after graduation made his memory talent useless.

Traditional memory methods, and the current scientific research on memory, are based on memory is a kind of knowledge accumulation process, a variety of existing memory enhancement methods and fast memory techniques, are to understand and analyze the memory for storage, and then through the search of keywords to retrieve memory and use, this memory method is essentially consistent with the principle of the Internet search engine.

But the weakness of the search engine is also obvious, its mode of operation is based on a large number of memory carriers and indexes, to achieve memory must continue to expand the carrier and establish indexes, this process has to pay a huge cost, which is also the traditional memory method is easy to get started, but difficult to master the problem, after all, most people are ordinary people, their brain capacity and reflection can not support more and more memory and index, only a small number of geniuses can record information like a computer.

However, there is not only one way to memorize, there are other ways of remembering that this unique organism is human.

For example, many people have long forgotten everything before the age of 3, but there will always be a few silhouettes of the years before the age of 3 in their minds, like the silhouette of a mother breastfeeding him and a father lifting himself high...... And so on, these memories cannot be stored by understanding and classifying, because the brain before the age of 3 does not have the ability to form logic, nor does it have the ability to accumulate knowledge.

At present, the scientific community's research on this memory mode is still in its infancy, and it is not yet possible to fully explain this phenomenon, but many people believe that the memory mode of human beings before the age of 3 has a great effect on improving the storage and computing power of computers.

If the development of computers in the first 40 years was the era of silicon crystals, the breakthrough in the field of computers in the next 40 years will be the era of biological computers, and the breakthrough point of biological computers may be in the study of this way of remembering.

Of course, Ren Pingsheng did not have the ability to develop biological computers, but he mastered this memory method very early without a teacher, and Ren Pingsheng named his memory method "holographic image memory method".

The "holographic image memory method" believes that human memory is the same principle as cameras and video cameras, which is to decompose various elements of things and record them through different carriers, and each recorded copy will be stored in the form of a hologram.

When using "hologram memory", Ren Pingsheng simulates his brain into an amphitheater, incarnates himself as an eye in the center of the theater, and the circumference around the theater is divided into countless small squares, and he transforms the knowledge and information he has absorbed through observation and learning into visual holograms and stores them in the squares.

For these holograms, he doesn't need to deliberately understand and analyze, just melt the elements and details into them, whenever he needs to call a certain aspect of information, immediately tune out the square where the hologram is located, zoom in and analyze it in front of his eyes, and then he can immediately obtain relevant content.

For example, if a geography class requires memorization of the location of each continent, the capitals of various countries, the routes of various straits, and so on, the common method of memorization is to memorize these geographical terms and store them in memory.

And Ren Pingsheng didn't have to memorize it at all, he directly scanned the entire globe into a hologram and put it into his brain, whenever he needed to call on geographical knowledge, he found out the square where the globe hologram was located, and his brain was like a movie constantly sweeping out the required direction, as well as the information it was rich in.

Europe and Oceania are separated by the Pacific Ocean, North and South America, and the Atlantic Ocean;

The fastest route from the Atlantic to the Pacific Ocean is the Isthmus of Panama;

Countries near the Isthmus of Panama include Costa Rica and Colombia;

Their capitals are San José and Santa Fe Bogotá;

Costa Rica's specialty is bananas, and Colombia's specialties are coffee and emeralds.

By extension, both countries have adopted an American-style presidential system of separation of powers, but Costa Rica's economic level is close to that of a moderately developed country, known as the Switzerland of Central America, while Colombia has always been in the stage of a developing country, with domestic drug lords and wars.

Although these two countries do not share a border with the United States, they are politically and economically inseparable from the influence of the United States.

Costa Rica can be called a tourist destination and financial center in Central America, which is inseparable from the large import of American capital;

The country itself was split from Colombia under the manipulation of the United States in order to control the passage of the Panama Canal and to ensure the smooth and rapid movement of the American navy and shipping between the Atlantic and Pacific Oceans.

Continuing to deduce, the reason why the United States attaches so much importance to sea power is precisely because it became independent from the British Empire as a colony, precisely because the British Empire is a country built on sea power.

After inheriting the dominance of the British Empire, the United States also had to do everything possible to ensure its global sea power, and the conflict between the sea power countries and the traditional land power countries was linked to the geographical conditions of the Eurasian continent and even the theory of the formation of the earth's plate drift......

By analogy, more holograms can be deduced from a hologram, and the connections between different images can be called at any time according to the needs of life, but there is no need to forcibly memorize and memorize knowledge.

In reality, it takes hundreds of millions of computing power to achieve the effect, and Ren Pingsheng can do it with only his own brain, which can be described as twice the result with half the effort.
