At the beginning, in order to prevent Fang Yun's rise, the various forces in the universe used backdoor software to improve the strength of the atmospheric transporters of this time and space. It even gave them the technology to surpass this era by 50 years.

But how much is 50 years? This year is 192 years, so even 50 years is only about 242 years. At that time, it was the third year of Cao Fang, the king of Wei Qi, the fifth year of Liu Chan Yanxi, the queen of Shu Han, and the fifth year of Sun Quan Chiwu, the emperor of Wu...... Obviously, there are still more than 30 years before the end of the Three Kingdoms.

If it is said that in the era of peace, then 50 years of technological development is actually quite terrible. It is not difficult to see the rapid development of various science and technology in the more than 20 years since the reform and opening up of New China. But in an era of constant war, where people have no fixed place to live, and most people live on the subsistence line, 50 years and 10 years, or even 5 years, seem to be no different.

At most, thunderbolts appeared, more advanced building ships or ships appeared, or Zhuge crossbows or wooden oxen and flowing horses appeared, and that's it.

What about the Thunderbolt, which can be stronger than the Xiangyang Cannon? How is the bed crossbow, can it be compared to the eight-bull crossbow? What about a strong crossbow, can it be compared to a divine arm bow? The repeater and the wooden ox and flowing horse are rare high-tech, but the former Fang Yun already has drawings here. As for the latter, the use of cement can quickly solve road problems.

Not to mention, there are already more than a dozen horse-use railways under construction, and the transportation problem is actually nothing.

The problem is, Fang Yun didn't know this! The enhancement of Liu Bei, Cao Cao and Sun Ce, and even the emergence of technology, were completely operated after shielding the perception of the system, so even the system did not detect it.

Because of this, when he learned about their secret savings technique, Fang Yun had to be cautious. But at this moment, he just thought that as he continued to climb the science and technology book, the three of them were stimulated to embark on this path.

In fact, if you take a closer look at the other princes, it is not difficult to find that there are actually only three of them. The other princes still do whatever they have to do, climbing the tech tree or something. It wasn't something these princes and warlords liked to do in the first place. In all dynasties, there is nothing more than this.

The master is in the world, and Fang Yun has never doubted the scientific and technological level of the big man. In fact, there seem to be some disciples of the Mo family in this era, but it is difficult to become a monk. And it takes a lot of money to play with technology, so it's inevitable that Momen will wither a little. In particular, Momen also stipulated harsh and simple rules, so that the number of disciples was naturally further reduced.

By Fang Yun's side, there was actually a disciple of Momen, and that was Wang Yue. It's just that he's from the Ranger Momen faction. It is not clear what happened to the Gewu faction. These rangers are actually like the paladins in the Momen, belonging to the side line. Being able to read and write is actually very rare, but as for climbing the science tree or something, it is naturally impossible.

And because of this identity, it is difficult for him to take a formal path. At least now that Confucianism is prevalent, these peripheral disciples who are not even considered descendants are not recognized by Confucian disciples at all, and even if the descendants come over, they may not be able to get equal status. It was Liu Hong who appreciated him, which made him the founder of the Han Soul Organization.

Except for Momen. Some craftsmen occasionally find some wood, iron and other tools. It can be regarded as civilian, but also military. It's just that they have just made a name for themselves in the local area, and they will be approached by the family.

Forced buying and selling may already be considered the lightest, and it is not a strange thing to force their family to sell themselves into slavery, or even destroy their families for the sake of monopoly. People who don't have the strength can't even protect their own technology at all.

It is precisely because of this that some technologies that are tens or even hundreds of years ahead of the world cannot be popularized, and even in the process of monopoly. For various other reasons, the technology is lost. There is no greater tragedy in China than this......

The Maisons, in particular, would rather let the books rot in the attic. Covered with dust and cobwebs, it will not be shown to the poor or ordinary people. Even if no one knows how to read these books for a long time, even if they don't care about them.

Maintaining an absolute monopoly on knowledge is the fundamental reason why the Maison has been able to become a Maison.

For the average person, these books, these techniques. This knowledge is a closely guarded existence. They would set up one protection after another, and even people would choose domestic slaves to ensure loyalty to the surname. So, it's almost impossible to steal.

However, is Fang Yun an ordinary person? It's a pity that he's not!

The members of the Han Soul Organization and the members of the dark department all over the world are the hard work of Liu Hong and Zhang Jiao for more than ten years. Even those families did not know that their house slaves, the most docile and obedient house slaves, were themselves likely to come from these two organizations. Before becoming their domestic slaves, they had been baptized by both organizations.

They are loyal on the surface, but in fact, in terms of fundamental interests, as long as the Han Soul or someone from the dark comes to the door, they will naturally know how to choose. And such two powerful intelligence networks, after Fang Yun's integration, have merged into the largest intelligence organization in Huaxia. In this regard, I am afraid of any Yuan valve, or any Yang valve, and there is no way to compare.

The night is dark and the wind is high, and it is a good weather for killing people and setting fires. More than a dozen black shadows turned into a mansion outside Puyang. Not long after, more than a dozen men dressed in domestic robes came to the workshop under the leadership of the old butler.

"You only have half an hour, and after that, whether you finish copying or not, you must leave quickly, otherwise I won't be able to protect you!" The old butler said to the housekeepers very seriously.

"Whoa!" The servants whispered in response, and then entered the workshop.

It's late at night, and no one is here except for the night watchman. The workers had gone back to rest, and the whole workshop was deserted at the moment.

These families barely have their lights lit, and the lights will reveal their tracks. Luckily, the moonlight was very bright today, and they didn't suffer from night blindness. Even because of their special occupation, they even specially trained their eyes to ensure that even at night, they can see most of the drawings and all kinds of books.

At this moment, each of them had ten blank pieces of paper in their arms, as well as a charcoal pencil. This is to be able to record the technology more quickly, and this is what they will do.

Half an hour is not a long time, but it is not short, enough for them to walk around the workshop. Then write down everything that needs to be written down. Even, when leaving, they kidnapped the foreman.

The next day, more than a dozen family members were found red. Lying naked in the grass. Apparently there is no way to wake up again. There was nothing lost in the amplifier, but the foreman was missing.

"Who the hell is it? Can you find out?! When Cao Cao got the news, he was immediately furious.

That wasn't the only workshop that happened, more than thirty workshops for different purposes he had arranged had actually found an invasion. The most important thing is how people invade. I couldn't find out. Although nothing was lost in the workshop, the excellent foreman was missing, which would have a great impact on their construction progress.

"I've asked the steward, and everything is normal, and nothing unusual has been found." Xiahoudun shook his head.

"A dozen people were killed, the foreman was kidnapped, and nothing happened?" Cao Cao was obviously incredulous.

"Master, it's not good!" At this time, the housekeeper ran over in a panic.

"I'm so good, sir! What the hell is going on? Cao Cao was also just irritable and gave the steward a punch. Then he asked impatiently.

"Ahem...... Master, your study seems to have been turned over by someone, and it's a mess inside! The steward shouted.

Cao Cao's face changed suddenly, and he immediately came to the study. It looked no different than usual, but only he and the steward knew, and some subtleties were clearly different.

He quickly pulled open a dark compartment, only to find that several of the drawings inside had disappeared. This is just a collection of very advanced technical drawings. In particular, there is a revised drawing of Du Kang, which is the one he values the most. However, these drawings just disappeared......

"Who did it!" Cao Cao roared like thunder.

"I don't know this little one! Yesterday was a quiet night. The guards didn't react either...... Master, is it a thief? The steward had thought of something.

"Check it out for me right away!" Cao Cao couldn't help but feel a little chilled.

Today you can quietly come in and search his study, and tomorrow, will you be able to enter his bedroom? Thinking about yourself while sleeping. Being killed by someone who doesn't know who is directly killed with a knife is not pleasant!

Fortunately, his bedroom has always been the most closely guarded place. Not only are there people from the Tiger Guard Battalion guarding the periphery, but there are also some dead soldiers raised by the Cao family to escort them. This is also the main reason why he Cao Cao has been able to live unharmed until now.

Ultimately. His grandfather was the great eunuch Cao Teng, although there was no persecution of ministers during his reign. But it still caused him and his father to be thrown into the eunuch line. Since he was born, there have been many rangers who assassinated their father and son in the name of killing the eunuchs, and if it weren't for the tight guards, he Cao Cao might not have been able to live until now.

By the afternoon, at least three suspects had been tortured, but they had preferred to die rather than say a word.

"It's three dead men...... The old slaves are also at fault in this regard, who would have thought that those house slaves who have lived in the Cao family for several years are actually dead soldiers who have been planted by others...... The old slave is a capital offense! The old butler knelt down directly for Cao Cao.

"No one is to blame for the deliberate and insidious for years. It's just strange that they have been dormant for years, why are they only launched now? Also, by researching the people they have been in contact with regularly, I want to make sure that the people around me are pure! "Cao Cao is not suspicious, but in this troubled world, suspicious can live longer.

As for Liu Bei and Sun Ce, the same thing is happening, but the technology in the hands of the two is less, so the danger is not very great. However, after learning that his technology was stolen, he was inevitably depressed, and then increased the intensity of guards. However, as long as something fundamental does not change, then there is no way for them to avoid being infiltrated again.

On the other hand, after more than ten days, Fang Yun got a lot of technology, and even got more than 50 outstanding talents. The only thing that makes him unhappy is that he has most of the techniques, and even seems to be very backward.

For the sake of these backward things, he even sacrificed more than a dozen members of the dark department...... It's really not worth thinking about...... (To be continued.) )

PS: Don't say 'the shadows are so powerful, why not assassinate directly', first of all, assassination is a taboo, whether it is successful or not, it will be spurned by others, at that time, it was an era of looking at reputation, and the reputation was ruined by that person. Besides, it is impossible for others to have no ability to fight back at all, that is, they did not attack directly, otherwise, once they get close to the other party's bedroom, they are afraid that under strict defense, none of the people sent over will be able to come back alive.
