That night, head back to the dormitory. Zhu Ping'an and Qi Ming were both talking about what they had seen and heard, and like Du Bixing, they also received a shocking first lesson.

However, there is a difference in the content, Zhu Ping'an watched the history of how humans used demon genes to breed alien beasts, while Qi Ming watched the scene where Li Taibai once drank and wrote poems, and his mind killed thousands of enemies.

"Tell you!" Qi Ming said excitedly, "There are so many beautiful girls in our Taibai Academy, just in my class, there are only three of them with eight points!"

Zhu Ping'an snorted: "I can't imagine that it is an artificial beauty with plastic surgery or modified genes!"

"No, absolutely not!" Qi Ming emphasized, "Ordinary people can have plastic surgery and modify genes. What we are pursuing in our cultivation is genetic evolution, and if it is modified, it may cause genetic cancer or even become deformed. No one usually does that!"

Du Bixing nodded and agreed: "That's true, theoretically speaking, with the evolution of genes, the physique and appearance of human beings will also tend to be the perfect expression of their natural form, so it is normal for there to be many beautiful women." ”

"Is it normal?" Zhu Ping'an said with some regret, "We haven't seen a single woman in genetic engineering, but there are a lot of pseudo-mothers!

"It's okay, just as you are a rich second generation, it's not a matter of minutes to find a girlfriend?" Qi Ming said.

"That's not interesting. ”

......

Everyone chatted, and Du Bixing practiced in the common practice room of the dormitory. Qi Ming's cultivation of spiritual power does not need a practice room very much, and Zhu Ping'an is a liberal arts student who studies genes, in addition to ordinary exercise, he does not need a practice room, this practice room, Du Bixing can be used almost alone.

There were some basic exercise equipment in the practice room, and he did physical training before he began to practice the "Fighting Chapter" mental method.

The ball girl mimicked and said, "Master, you have now refined the copper skin, and then you need to practice iron bones! ”

"The school's gravity retreat room is perfect for practice, but you still have to make some preparations, master. ”

"Do you want to take that?" Du Bixing asked.

"Hmm. "The bone is the scaffold of the body, the hardest part of the body, and it is not easy to change. Moreover, the bones of adults have stopped growing, and because of this, it is very troublesome to strengthen the bones. If you let the bones become in a state of growth before you practice, then you will practice faster. ”

Du Bixing took out a small bottle of blue potion, which was the "bone correction potion" he bought on the Hunter Alliance network. ”

This is not a medicine for spiritual practice, but a medicine that has been used for bone injuries and deformities. Its function is to soften bones and promote bone redevelopment.

Normal people would never use this kind of thing to assist in their cultivation, first, they do not have the cultivation method of forging bones, and second, this medicine still has some side effects on the human body.

However, none of this is a problem for Du Bixing. The ball girl infiltrates her own tiny particles into the potion and strips off the molecules to minimize some harmful substances.

"Master, take this medicine, after five hours, you will feel weak bones and weakness all over your body. The bones start to grow twice, and it will be very painful during this period, so you have to be mentally prepared. ”

"Hmm. Du Bixing nodded cautiously, he was already mentally prepared.

Du Bixing first activated the Force to regulate the body's qi and blood to one side, and then began to take the potion. When the medicine enters the throat, it has a disgusting taste.

The ball girl said, "Master, continue to practice. The ingredients of this potion are damaging to the bones, and you have to use the Force to repair your body. ”

Du Bixing continued to practice, and for the whole night, he did not go out in the practice room.

Before you know it, the night passed quickly.

"Master, master, it's time to get up!" the ball girl whispered to Du Bixing's ear, gently waking him up.

Du Bixing was in a trance, and when he practiced until midnight last night, he suddenly felt a sense of sleepiness, probably because of the effect of the drug, and he fell asleep directly.

He tried to stand up, but his legs went limp and he almost fell. Fortunately, the ball girl flew in front of him and resisted him with her slender body, so that he did not fall.

"Sure enough, I feel that my whole body is soft and I have no strength!" Du Bixing slowed down for a while before standing up on his own.

He now feels like an old man with osteoporosis, and he has a hard time walking.

The ball girl comforted: "This is normal, the bones open and develop again. ”

"Well, it's time to go to class. However, in my state, I am afraid that it will be a little embarrassing to go to the practice room. Du Bixing went to the pyramid teaching building of Zhenwu Academy.

The second basement floor is the primary gravity practice room. The gravity training room here has a relatively low gravity amplification level, which is suitable for new students to practice.

"Du Bixing, your face is not very good-looking today. Wu Han, a classmate I met yesterday, said.

Du Bixing smiled bitterly: "The cultivation is too strong. ”

"Excessive cultivation?" Wu Han said in surprise, "You're too hard, it's just a matter of starting school." Besides, the instructor didn't arrange any cultivation tasks, so don't get away with it. ”

"Well, it's fine. Du Bixing has barely adapted to this state.

"Everyone is here, then start the class now!" shouted the instructor Yan Jingrong.

"This is a low-level gravity practice room, and there is an amplified gravity field in it. Practicing in it allows you to hone your body from the inside out. ”

"Your first assignment is to spend five hours in the gravity training room!"

Yan Jingrong warned: "The hypergravity environment is something that every martial artist has to adapt to. The gravitational pull of each planet is different, and when you travel to other planets, you must have a strong body that can adapt. ”

"It may be a little uncomfortable at first, but as long as you persevere, with the cosmic force in your body, your body will be greatly strengthened. ”

"Now, everyone chooses the gravity practice room according to their physical fitness. I suggest that beginner primordial warriors choose triple gravity, intermediate primordial warriors choose five times gravity, and advanced primordial warriors choose ten times gravity. Let's get started!"

After Yan Jingrong finished speaking, the students chose the gravity amplification according to the criteria he said. Du Bixing was about to choose five times the gravity, but the ball girl hurriedly displayed on the smart hand: "Master, your bones are weak now, you should choose the low gravity room to practice." ”

"What about three times?" Du Bixing asked in a low voice.

"Well, let's take a look at the physical condition first, triple times is not good, and then change to a lower one. ”

Du Bixing walked into a gravity room and turned on the triple gravity field. In the room, the air pressure began to increase, and Du Bixing felt that his body began to become heavy, and even his internal organs were under invisible pressure.

The gravity gradually increased, Du Bixing's breathing became heavy, and he felt a sense of weakness from his bones, as if it was extremely difficult to support his body.

This is different from carrying a heavy load, when carrying a heavy load, the bones are supported, and other muscle tissues assist, and a person can resist several times the weight of oneself.

But the gravitational field is pressed on every cell, and the pressure inside and outside the cell will change, and if you are not careful, you will be injured.

"I can't breathe, I feel like my bones are going to break!" Du Bixing gritted his teeth, his figure gradually bending.

The ball girl proposed: "Master, you better use twice the gravity first, and then triple it when the bones are stronger." ”

"Hmm. "Du Bixing mediates the gravity field equipment and replaces it with twice as much.

"Huh?" Yan Jingrong noticed this situation, and the other students, although they were a little uncomfortable at first, they all persevered. There are also good physical fitness, and they can exercise directly in seven times gravity.

This student, he can't hold up three times, can only use two times? He frowned and walked over to check the situation.
