Zhou Huan flipped through the high school textbooks on the light screen, only to feel that his head hurt badly, he just wanted to pull the system and beat him up, and ask what kind of learning copy this is?

The high school textbooks on the light screen are one of the few benefits that come with the system (high school textbooks are not equal to knowledge exchange, you must study by yourself, and it is strictly forbidden to teach them to others if you don't understand them, and at the same time, extracurricular tutoring textbooks must also be published by regular publishing houses, and the messy book system will not scan them), Zhou Huan can call it up when he wants to learn, but why is there no technology in these how to make steel and gunpowder?

Well, there are some in it, but it's too simple, and all kinds of tedious crafts are not mentioned, and it's very difficult to climb the tech tree.

This kind of thinking continued until Zhou Huan was eating, so that the little girl Tang Yunniang thought that Zhou Huan's appetite was not good.

"Nothing, I just want to have problems with the forging side. ”

It is a good thing to defeat the besieging enemy and occupy Chuzhou City, but this does not mean that you can sit back and relax, the next siege of the Northern Wei Dynasty will be carried out in two or three months, and the next time the army will not be 50,000, but 100,000 or more.

Now that the mission has become a military group, everyone who has completely fallen on the thief ship has tried their best to expand the army, and Chuzhou City has become a large barracks, and they have given up illusions from top to bottom - if Chuzhou City is breached, it will be slaughtered 100%.

Zhou Huan, who killed Murong Shiqing, did not choose to leave, he was not the kind of person who had no beginning and no end, and he vaguely guessed the reason why the system put him in this era.

A modern high school student has returned to the chaotic ancient times, surviving on the cusp of the limelight, he has no strong force, only all kinds of knowledge in his chest can keep him alive.

If Zhou Huan didn't have the magic power of Transfiguration, he could only witness the tragedies that happened in the northern land, and he would eventually choose to use the knowledge in his chest to change the world, and high school textbooks were his best tools.

Chinese Classics, Historical Classics, Mathematics Books, Physics Books, Chemistry Books, Natural Wonders, Sports Classics...... Everything is the crystallization of knowledge accumulated by human beings for thousands of years, and the only drawback is that he needs to study it well.

I don't care about the success or failure system of this copy, Zhou Huan's struggle in this world will naturally produce a lot of worries and regrets, and he will definitely regret why he didn't study well when he was in school, and he will try to carefully find the applied knowledge from high school textbooks to climb the science and technology tree - and what is needed to climb the science and technology tree is all aspects of knowledge, each of which needs to be better studied, so that Zhou Huan's learning will naturally make great progress.

"Brother Zhou, you've done well enough, don't tire yourself out. ”

Tang Yunniang's eyes were full of admiration when she looked at Zhou Huan, not only because of Zhou Huan's achievements, but also because of the knowledge that Zhou Huan had taught these days.

The health regulations for the treatment of the injured and sick, the new skills of building steel, the method of using loess to make sugar, etc., all made those craftsmen dumbfounded, and Tang Yunniang, who was following behind, naturally admired Zhou Huan even more.

"I'm not tired, I just sigh that I didn't study my knowledge well back then, and I can't do many things now......"

"Aomine, you are too humble, I have never met anyone more knowledgeable than you. ”

Qingfeng is Zhou Huan's word, and it is Princess Pingyang who speaks, this female fox always likes to come to Zhou Huan's mansion to eat these days, or after she is ready to eat, she will bring it to Zhou Huan - after Zhou Huan killed Murong Shiqing and came back, Princess Pingyang allocated half of the city guard mansion for Zhou Huan to live, and the two are now neighbors.

"I'm far behind, don't talk about it, Yun Niang, how is your True Qi Breathing Method?"

"It's been a little bit done. ”

Tang Yunniang's words made Zhou Huan blink and blink again.

The cheats don't say that ordinary people can only get started in three or five years, and they can only barely feel a trace of qi now.

A quarter of an hour later, Zhou Huan decadently put down Tang Yunniang's wrist, the little girl was really already at the beginning, and her true qi flowed in her dantian like a little mouse, and her progress far exceeded Zhou Huan's.

"It's a ......"

Zhou Huan couldn't help but despise himself, why is this body not as good as Tang Yunniang.

"Brother Zhou, how long do I have to cultivate before I can be as powerful as you?"

Tang Yunniang glanced at Princess Pingyang and asked with a smile.

"It's probably going to be a few decades later, but the eldest brother has passed on all the things in the box to you, Your Royal Highness Princess, do you want to learn these things?"

"Can I learn too?"

Princess Pingyang's face was straight, and she nodded hurriedly.

"Of course you can, that's it, you worship me as a teacher, and Tang Yunniang is the same, you are much older than Yun Niang, you are the senior sister, Yun Niang is the little junior sister, is it okay?"

Zhou Huan waited for the two girls to bring him tea and water, but unfortunately all he gained was two white eyes, which made him vaguely have a bad idea in his heart.

Princess Pingyang is the most beautiful woman he has ever seen, even those female agents in the last world can't compare to her, her beauty can be summed up in four words, the country is beautiful and fragrant.

However, he can only live in this world for ten years, what will Princess Pingyang do when the time comes?

As for Tang Yunniang, Zhou Huan has no idea 100%, and it must not be okay to do it to the Lin squad leader who looks like Lori.

"I don't have more than ten years to live. ”

Zhou Huan let out a long sigh and said to Princess Pingyang.

When Chen Ming entered Chuzhou City, it was already three months later.

Chen Ming is a distant relative of the Liang Dynasty, because he is shrewd and capable, he has always been very valued by today's son, and he insisted that he could not make peace, saying that peace can only make the war come faster.

Sure enough, after entering the Northern Wei Dynasty with the family group, so many things happened, Helian Bobo was not a king, and used that kind of unpopular means to tease the Southern Dynasty and the mission - this is already a naked insult, and he doesn't take the Southern Dynasty seriously at all.

The carrier pigeon passed a lot of news, when they learned that the mission was besieged in Chuzhou City, the Southern Dynasty vomited blood angrily, and the Northern Wei Dynasty deceived people too much!

At this time, the envoy of the Northern Wei Dynasty came to the Southern Dynasty, and actually asked the Southern Dynasty to explain clearly and cede the land and pay compensation!

Chen Mingcai angrily reprimanded the envoy in the main hall, but how could the power of words compare to the threat of a knife?

However, the change in the situation was beyond everyone's expectations, who would have thought that Princess Pingyang would be able to make such feats in the Northern Wei Dynasty, after killing Helian Chunshui, she also killed Helian Tieqi and Murong Shiqing one after another, and broke the hundreds of thousands of troops of the Northern Wei Dynasty - Chen Mingcai was a little suspicious about this number, but the heads of Helian Tieqi and Murong Shiqing were confirmed.

Although the envoys of the Northern Wei Dynasty were still clamoring in the court, they privately expressed their willingness to negotiate, and they did not want to pay compensation for the land cution, as long as Princess Pingyang surrendered and handed over Zhou Huan, everything could be discussed.

The envoys of the Northern Wei Dynasty even said that the peace could also be canceled, as long as the Southern Dynasty sent Zhou Huan's family to the Northern Wei Dynasty.

This is also the first time that Zhou Huan has been valued by the Southern Dynasty, and the monarch and ministers are very strange why there is such a proposal - the Northern Wei Dynasty said that Princess Pingyang's rebellion was prompted by Zhou Huan alone, otherwise everything would not have developed like this.

The lack of transportation prevented the Southern Dynasty from getting more information, and although Chen Mingcai smelled something unusual, he finally made a difficult decision to pretend to be a merchant and go to Chuzhou City to find out what was going on!

If there is no major change, the Southern Dynasty will die within 20 years!

This is the inference of people of insight in the Southern Dynasties, so now that the big changes are ahead, why not take a look?

There were constant risks along the way, but fortunately, Chen Mingcai's identity prepared in advance opened up a lot of relationships and came to Chuzhou City.

But it was also at this time that the exact news came that the 200,000 troops of the Northern Wei Dynasty were coming towards Chuzhou City!

When Chen Mingcai entered Chuzhou City, Murong Longcheng was serving as a shopkeeper in the teahouse, which was not far from the city guard's mansion, and many officials and soldiers came to drink tea every day.

From the appearance, it is not obvious that he is the personable son of the Northern Wei Dynasty, and he is more like a delicate businessman with a beard.

His current identity is the distant brother of an official in Chuzhou City, and the teahouse is a dark spot of the Murong family in Chuzhou City.

Four months ago, Murong Shiqing, the head of the Murong family, died in the battle under the city of Chuzhou, and there were all kinds of different voices in the Murong family, revenge is the mainstream, but there are still some people who think about why this battle was lost so badly?

The guards who fled back told Zhou Huan's ghost-like skills, telling everyone that the battle of Chuzhou City was a victory for Zhou Huan alone, and Murong Shiqing did not make any mistakes in arranging the troops.

The Murong family first started with raising horses, and has seen many historical changes in the past three hundred years, three hundred years ago, a Han became a Wuhu, because the Han people had iron armor, and then the appearance of stirrups gave the cavalry overwhelming power, and then ......

When a very influential new thing appears, stupid people choose not to see it, and smart people will study hard, just like the iron armor and stirrups and crossbows of the year, and those who do not accept it will only be quickly eliminated.

Murong Longcheng came to Chuzhou City, he wanted to know Zhou Huan's secrets and learn Zhou Huan's skills, for this, he could do whatever it takes!
