The Xiao family's library is located inside the patriarch's mansion and is heavily guarded.

With Xiao Mingsong's guarantee, Qin Feng was able to enter the mansion smoothly, and could stay inside for a day, freely consulting and watching all the materials and documents, but most of them could not be brought out.

In front of a slightly old three-story building, after the guards verified Qin Feng's identity, they nodded and signaled that he could enter. He pulled out a pack of cigarettes and tossed them to the other party, and walked into the library door.

A maid of the Xiao family followed him, obeying orders at any time, and naturally had the responsibility of monitoring secretly.

The space inside is not very large, and the rows of thick wooden shelves are filled with large books, including historical biographies, human geography, economic treatises, academic research, etc., most of which are works from the old era. Of course, Qin Feng's focus is not on this, what he wants to watch most is books in the field of science and technology.

Looking at the rows of bookshelves, in the invisible void fault, the starship phantom flickered slightly, and the light swept by, and the contents of all the books were copied word for word into the database in the starship center.

In the central area of the library, Qin Feng saw two large server hosts, which stored a large number of documents and materials, and could freely query the things he needed through the personal computer terminal when needed.

At this time, a strange woman in a red dress was busy on the host with her head bowed, her back graceful and plump, her waist full of hands, and her long straight black hair with a few simple and delicate ornaments.

Hearing the footsteps, she turned around in a little surprise and saw the strange man who had accidentally intruded, on his delicate and bright face, his black eyebrows were slightly tightened, and he asked unhappily, "Who are you?" How did it come in here. ”

The maid next to her hurriedly explained: "Second Miss, it's like this......"

She told Qin Feng's origin, the girl in the purple skirt softened her expression, looked at him with interest for a while, stretched out her slender hand and said, "I'm Xiao Yuehan, it's a pleasure to meet you." It's really not easy to snatch more than half of the Feng family's territory in one go. ”

"I'm glad to meet you, too." Qin Feng stretched out his hand to shake her.

This Xiao Yuehan is the second daughter of the head of the family, and now she is twenty-four years old, and she is already the strength of a tenth-level evolutionary, because her appearance and strength are first-class outstanding, she has naturally become the object of competition among young people from all walks of life.

Qin Feng was not interested in talking to her too much, and after a few simple conversations, he began to concentrate on checking the information in the host, which was his primary goal of coming to Mingchuan City this time.

In this era, as the carrier of civilization, all kinds of materials and classics have been monopolized by major families and power organizations, and the middle and lower class civilians are busy with their livelihoods all day long, and they basically have no opportunity to come into contact with this valuable knowledge. Only those children who are born into the upper echelons can have the opportunity to receive a systematic and complete education.

Due to the sharp decline of the population and the lack of resources, the level of technology in many fields stagnated in 2076, at the beginning of the catastrophe, and there has been little progress since then. Of course, out of the need for survival, the level of science and technology in the field of armaments has been steadily improving, and most of the limited resources have been concentrated in this area.

It didn't take long for Qin Feng to discover a lot of interesting content, such as more advanced information storage technology, gene medicine technology, new material technology, as well as a series of key fields such as aerospace, bioenergy, artificial intelligence, etc., although most of them are old materials before the catastrophe, compared to the level of scientific and technological development in the main world, it is already an out-and-out black technology.

He quietly communicated with the starship, copied the entire database content in the main engine, and waited until he returned to study it slowly. Although there are many things in it that are not perfect, even a small part of it can be called a treasure of immeasurable value. After bringing it back to the main world, it may be able to improve the technological level of some fields in China for more than 20 years.

“…… I don't know if there will be a chance to go to the top of Kunlun in the future, the database there should be more perfect, and more technical literature should be retained, if it can be copied, it will make a lot of money. Qin Feng thought to himself.

Time passed unconsciously, Qin Feng comprehensively observed the achievements of scientific and technological progress in the old era, in this world, the country located in the Eastern Continent has stood on the top of the Blue Star, and has established long-term manned scientific research and research bases in the deep sea, synchronous orbit, the Moon, Mercury, and Mars.

Key technologies such as thermonuclear fusion, quantum computers, and artificial intelligence have matured and been put into commercial operation, submarine residential areas, space workshops, and lunar administrative villages have been established, and mining sites on asteroids and the moon have been operating stably for many years.

Several unmanned exploration spacecraft have flown out of the solar system and as far as the depths of the Oort clouds, and large manned research spacecraft have reached as far as Saturn's major moons and discovered life in the deep ice of Satellite 6.

In the laboratory, scientists have constructed a complete theory of space transition, and after preliminary experimental verification, perhaps in another twenty or thirty years, human civilization is expected to truly break the shackles of the speed of light and open a new chapter in the sea of stars.

Moreover, the continuous progress of biological gene technology and the popularization of primary gene optimization technology have made the average life expectancy of human civilization reach 120 years, and the life expectancy of upper-class people even exceeds 150 years. Organ transplantation, anti-aging, and disease-causing gene repair have all become popular technologies.

Regrettably, the Catastrophe unexpectedly struck and snuffed out all the glorious prospects of the entire civilization. The human society that survived the catastrophe could only begin to adapt to the harsh environment beyond recognition, and silently struggled to regain the dominance of the Blue Star.

In the new era, some experts have estimated that it will take at least 150 years or so for human civilization to repair the environment and restore its overall strength before the catastrophe, provided that no new major accidents occur, such as large-scale devastating civil wars, new invasions of intelligent creatures, and so on.

However, at present, it seems that it is not very likely that this kind of hope for human civilization will recover smoothly, because there is indeed more than one new alien intelligent species on the surface of the planet, and Qin Feng has seen two of them with his own eyes.

Fortunately, these intelligent species are only suitable for living in high-radiation environments and their populations are scarce, so they cannot pose a major risk for the time being, but it is difficult to say what will happen in the future.

The vintage wall clock on the wall rang several times, signaling the end of the day, and the sky outside the window visibly darkened.

Qin Feng stood up from his seat and was surprised to find that Xiao Yuehan hadn't left yet, still sitting opposite and reading intently.

Although he was a little strange, he did not take it to heart, said hello politely, and walked out of the main entrance of the library with the maid.

Xiao Yuehan came to the window, looked at Qin Feng's departing back with dark beautiful eyes, and suddenly asked, "Can he return to his own territory alive?" ”

A few seconds later, a faint voice sounded from mid-air: "It's difficult, there are too many people who want him to die, especially Xiao Yusheng hates him to the core!" So ......"

"That'...... Shall I give him a heads-up? ”

"It's up to you, Second Miss, to consider, but if he can't even survive such an ordeal, it doesn't seem to deserve your further attention."

"Okay......"
