"Since the Great War 300 years ago, the three empires have deployed a large number of space exploration equipment in northern Xinjiang, and set up special observation teams to monitor the northern Xinjiang region throughout the year. As soon as space begins to be unstable, entire continents, including the Sea Clan, will begin preparations for war. ”

"So you mean that space fluctuations are now observed again?" Li Mu asked a little nervously.

Li Mu also learned some things about the Outlands from books, which are races that do not belong to this world, they have the same wisdom as humans, and they also use cards to fight. It's just that the way they use cards is more savage, and the way they use cards is very different from the direction of human card development.

The people in this world where Li Mu is located initially created a variety of cards by imitating the patterns on the card beasts, and then used the card instrument to analyze the cards, and the energy cards to drive the cards to fight.

The cards of the Outlands are used differently, they don't need a card ceremony, but instead integrate the card directly into the body. In the beginning, humans also walked this route, but the physical fitness of human beings was simply not able to sacrifice multiple cards at the same time, and the body of ordinary people could only accommodate one or two cards.

If you can only hold one card, then this card will absorb the energy of the human body to drive, and if there are two, then you can choose one of the energy cards for blood sacrifice, so that you can barely fight without using the card instrument. However, the replacement of blood sacrifice cards will bring a lot of damage to the body, and the fragile physique of human beings is easy to be injured if they change cards frequently, so the method of appearing blood sacrifice cards has been eliminated since the card instrument.

This method couldn't be more convenient for Outsiders, who are generally several times more physically fit than humans, and most Outland adults can hold five or six cards after training. However, the cards after the Blood Sacrifice are bound to the body owner and cannot be given to anyone else.

The damage caused by changing cards doesn't have a big impact on them, the only trouble is that it takes a lot of time to change cards, and it takes a certain amount of time for new cards to blend perfectly. They usually can't change cards in time for battle, which is a cut from the flexible card instruments, but the Blood Sacrifice cards are far more powerful than the card cards more than make up for it.

It's the same weapon card, and the weapons summoned by using the card instrument are just weapons, and how to use them skillfully still requires the user to practice continuously, but the weapons summoned through the blood sacrifice card are different, and those weapons are like their own arms to them, so they don't need to do too much training at all.

The difference in how you use the cards may not determine the outcome of a battle, but the outlander's card-making ability is much stronger than this world, and a powerful card can often determine the outcome of a battle. In the course of previous wars, there was a record of an outland powerhouse transforming into a giant beast hundreds of meters tall and razing a city to the ground. In the end, the human race united many strong people and released the strongest spell card at the time to repel the opponent.

"Yes, although the current fluctuations are not very strong, and it may take decades for them to really break the spatial barrier, but no one dares to joke about this matter related to the life and death of mankind, so the Federation has increased its efforts to cultivate card makers and card repairs in recent years."

"Couldn't humanity develop the technology to block space? Are those unstable spatial fluctuations caused by Outlanders? ”

"According to research, this spatial fluctuation is caused by the weakening of spatial barriers caused by the intersection of different worlds, and it is during that time that the outsiders took advantage of the invasion."

"As for the space blockade you mentioned, the Federation and other countries have also been studying it over the years, but the scope that can be blocked is too small, and it is a drop in the ocean compared to the range of space fluctuations."

"How do you know so much news? These must be confidential. ”

"You don't have to worry about this, now the first thing humans should face after the end of the civil war should be the Sea Clan, and you will naturally know this news soon." The middle-aged uncle was a little thirsty after saying so much.

After listening to these explanations, Li Mu roughly understood the meaning of the federal school.

"You understand why there are so many dueling arenas in the school now, right?"

"So that the students can go to war at any time?" Li Mu frowned and asked, he didn't want to go to the battlefield, especially now that his strength had not yet developed.

"In order to keep people bloody, not to consume the will in a peaceful life."

The two chatted for a while, and a conversation with the middle-aged uncle made Li Mu feel a little more relaxed, and saw that the time was almost in class, so Li Mu said goodbye to the other party and flew towards the teaching building.

"These wings are really good things, but I don't know if they can be mass-produced, and the Federation's flying machines are simply not too rubbing."

After Li Mu left, the middle-aged teacher took out a notebook and began to write the report continuously, and he would hand the report to the new principal later. In the information, Li Mu's battle from the beginning of school to noon today has been recorded, and the conversation just now is even more accurate.

In the afternoon, classes are in shape and physical education, and the teaching in federal card schools is generally two consecutive classes of the same course, with a half-hour break in between, followed by the next class.

Li Mu's two-dimensional cards don't need much knowledge of the shaping module at all, but Li Mu found that the intelligence of his body is indeed very high, at least the content of this book Li Mu has no problem understanding, the trouble is the memory of those lines and symbols.

Chen Jing, who was at the same table, thought that Li Mu was a master of shaping, and asked Li Mu a lot of questions, but fortunately Li Mu answered them all, otherwise it would be embarrassing.

Physical education in school is very different from that on earth, and it is not so much physical education as physical exercise. There are special exercise equipment in the physical education class, and the physical education teacher customizes a different exercise plan for each student.

This class is simply torture for Li Mu, what he doesn't like the most is sports, but the physical education teacher made him have to run 20 kilometers in two classes, and if he doesn't finish running, he is not allowed to leave the class, which is why physical education classes are generally arranged in the last period.

These twenty kilometers may not be a big deal for people who exercise regularly, but they are very scary for Li Mu, an otaku, and the physical education teacher will constantly adjust the kilometers in the later courses according to the situation.

When Li Mu left the exercise room with trembling legs, there were only seven or eight people left in the exercise room.

"Li Mu, you can eat something first, this is Lin Mo asked me to help bring it, he left beforehand." When Li Mu walked to the door, he heard Chen Jing's voice.

"What's wrong with this kid, he must be lazy to ask you to help." Li Muyi sat on the grass and took the lunch box in Chen Jing's hand.

"No, Lin Mo, this kid won't add chicken legs to me, and there are actually two big crabs." Li Mu looked at Chen Jing with some suspicion, could it be that this girl threw her leftovers here by the way.
