In less than five minutes of class, the battle guidance worth ten credits is over, and in the remaining thirty minutes, everyone has two choices, one is to pay ten credits again to receive one-on-one battle guidance, and the other is to spend five credits to enter the gravity training room to exercise on their own.

Lin Fan walked to the door of a small gravity room, brushed five credits, and then walked in, he chose to train on his own.

Mentor Erin had already pointed out his shortcomings very clearly, and he didn't plan to spend his credits on battle guidance until he had mastered the Spiritual Master's attack methods, because it was useless at all.

When he was fighting against the guide just now, because of the second defeat, he hadn't even had time to experience the feeling of the gravity room, Lin Fan first doubled the gravity, and suddenly felt that his body was twice as heavy, this heaviness is different from weight, it is directly acting on every muscle, organ, and even cell in the body.

When gravity doubles, ordinary people will feel very strained, and produce dizziness and nausea, and if you stay in this environment for a long time, the organs in the body will fail because they work too quickly.

However, at this time, Lin Fan's physical fitness was eleven times that of ordinary people, so double the gravity was nothing to him, and it could not have any effect on him at all.

The gravity of the gravity chamber slowly increases, and the gravitational force of two, triple, quadruple, and quadruple gravity is a tipping point, because theoretically, the average person may adapt to 2 to 3 times the gravity of the earth, however, at 4 times the gravity of the earth or more, the average human physiology will not be able to maintain enough blood flow to the brain.

When gravity reaches four times, if a fat man is 90 kilograms, his weight becomes 360 kilograms! In this case, he couldn't even stand up.

The gravity of the gravity chamber was still increasing, until after seven times the standard gravity, Lin Fan finally felt that his breathing began to become heavy, and his body began to have an anti-stress response.

He maintained the gravity to about eight times, and then walked to the equipment rack next to him, where there were all kinds of weapons and training equipment, and picked up a black sword made of all-metal, in the eight-fold gravity environment, the metal long sword that was originally only about fifty catties has now reached four hundred catties.

"Whew! Call! ”

With a few swings at will, the heavy metal sword made a whirring sound of breaking wind in the air, and after his body gradually adapted to the surrounding gravity environment, Lin Fan suddenly shook out a few sword flowers, swung his sword, and then began to practice.

Half an hour later, when he walked out of the gravity room, his skin was red, there was a faint white mist, and his clothes were wet with sweat, but the whole person felt an indescribable comfort, every cell in his body exuded infinite vitality, and the original genetic energy in the cells was about to bottom out.

The effect of practicing the sword in the gravity training room is much stronger than when it is usually outside, and the body is tempered from the inside to the outside, and if you can practice in this environment for a long time, it will help you improve your strength a lot, and these five credits are worth it.

The last class in the morning was a mechanical class, probably to take care of the new human beings, and at the beginning, some basic theories were taught, which was equivalent to reviewing the content they had learned before for the new students of the White Feather Star who had a certain foundation, so they directly chose PASS, and after Lin Fan took a look at the course introduction, he also left under the surprised eyes of the human freshmen in the classroom.

There are only nine human freshmen in Class C of the command department plus Lin Fan, three women and six men, and now there are only eight people left in the entire empty classroom, except for Ye Wen and Wang Wei, all of whom belong to special enrollment.

"Eh, what's going on with that man? Didn't he know that if he wanted to stay in the command department, he couldn't fail all the courses? ”

There was a boy with an inch of hair who muttered to Lin Fan's departing back, he was a special student of the No. 10 Base City, and his strength was very strong, he was only eighteen years old, and he was already about to reach the level of a junior hunter.

"His name is Lin Fan, he is from the third base city, he is a mechanic, today's lesson may not mean much to him, hello, my name is Wang Wei."

Wang Wei smiled mildly at the special student, at this time, he didn't see the kind of arrogance and superiority that he had shown in the Eric Planet exam before.

In fact, a child like him from a big family, in addition to learning to improve himself, there is also a purpose to get acquainted with the human geniuses here, increase his own contacts, there is no doubt that the freshmen who can enter the command system are the best of all the human freshmen, once they successfully graduate, their future achievements are definitely not small, and they belong to the potential stocks.

"Oh, mechanic? This is a very rare profession in humans, no wonder, oh yes, my name is Chen Ming, and I'm from Base Ten City. Chen Ming nodded at Wang Wei in response.

Wang Wei's eyes flashed, and he stood up and said, "There are still a few minutes before class, why don't we all get to know each other, after all, in the entire class, we human freshmen only account for a very small part, and we should unite with each other." ”

"Well, that's a good suggestion, aren't there clubs in the university, let's make a club too." Someone nodded in agreement.

······

What happened in the classroom, Lin Fan didn't know, he was now on his way to the school library, the area of the Hunter University was very large, if it was said to be a university, it was better to say that it was a college city, which was divided into many school districts, but now only the first school district was open to new students.

After about ten minutes, he came to a large building, which was the only library in a school district, and when he walked inside, he found that there were already many people inside, but almost all of them were white-feathered stars, and there was not a single bookshelf in the empty hall, only one seat.

Lin Fan casually found an empty seat and sat down, then picked up a virtual helmet on the armrest, inserted the student card into it, and put it on.

"Welcome to Library One, please choose." As the smart prompt sounded, a dense table of contents appeared in front of him.

"Help me pick out books on spiritual teachers." Lin Fan said directly.

The next moment, there were only three of them left in the dense catalog in front of me.

"Low-level Meditation Method Part I", "Basic Mental Power Weapon Production", "Spiritual Teacher Foundation"

"So little?" Lin Fan was slightly stunned, and then relieved, the first floor of the library is basically some basic knowledge, if you want to understand deeper things, you have to go to the second floor, but now the second floor of the library is not open to new students.

He tried to open the book "The First Part of the Low Level Meditation Method", but a payment prompt appeared in front of him, and he would pay 800 credits to flip through it, yes/no.
