2293, mid-December.

Operations zone, gravity simulation room, a certain training room.

"Hmph! Humph! Ha! Hey!" A figure was training indoors to practice boxing, sweating.

The figure's movements are very slow, but the punches they make give people a sense of calmness and strength.

When changing moves, the figure lifts his legs and moves a little stiffly, but when it is his turn to punch, the speed of the punch is almost the same as usual.

This person is nothing but Lei Yi.

He practiced in this gravity room for more than a week, and from the beginning he was discomfort, he has gradually adapted to ten times the gravity.

But his behavior also made Xuan Wuyan look at him with admiration. When the woman saw that Lei Yi was safe and sound under ten times the gravity, she even kuo Lei Yi had a good talent.

"If I hadn't been in contact with you for so long, I would have almost thought you were not a human being!" This sentence was Xuan Wuyan's original words.

Lei Yi had no expression after hearing this, and even pretended to smile foolishly for a moment, but there was no flaw in his heart, but he felt speechless.

What if I don’t act like a human being, what if I’m exposed?

After that, Lei Yi quickly devoted himself to cultivation, leaving this idea behind completely and not thinking about it.

It’s true that after training for so long, his cultivation has really increased a lot, and the effect of the gravity room is very significant.

Two hours later, Lei Yi walked to the corner of the gravity chamber, where there was a remote control.

He picked up the remote control, aimed at a robotic arm outside the glass window, then paused his fingers and clicked a few buttons.

The robot arm clicked several times on the outside console, changing the gravity in the gravity chamber from ten times to five times.

Suddenly, Lei Yi felt a sense of relief in his whole body, because the gravity at this time was only half as strong as he did during his usual training.

"The basic boxing technique has finally been completed. Next, you need to practice the moves, both the tiger biting fist and the elephant thunder fist!"

He soon entered the state of cultivation and began to practice the body tempering effect was not very good, but he was practical against the enemy.

After practicing for half a day, Lei Yi felt a little tired after a set of tiger biting fists.

He knew that his daily practice had ended, so he picked up the remote control and issued another command to the robot arm in front of the console.

After the robotic arm clicked continuously, the gravity in the training room began to weaken, and finally disappeared, and the door of the room slowly opened.

Lei Yi walked out of the training room and looked at the robot arm next to the console.

This object connects to a crawler-type base, which can move back and forth in the simulation room. If it is not necessary to use it, this object will dock in the corner.

Needless to say, this thing was written by Zhao Blacksmith, and the mechanical arm was designed to replace Xuan Wuyan.

After all, Xuan Wuyan is still a helper on campus and needs to work. It is impossible for him to come to the simulation room every day to train Lei Yi.

So this robotic arm became a tool to help Lei Yi adjust his gravity.

After completing today's work, the robot arm slowly drove to the corner, where there was a socket and wire that could help recharge the power of this product.

After Lei Yi walked over and operated it, he stopped caring about this thing.

When he left the gravity simulation room, he glanced at another training room, but there was no one there.

"Iron Niu didn't come today?" Lei Yi curled his lips.

Not everyone can practice the gravity simulation room. Lei Yi practiced here for more than a week, but he didn't expect to meet Tie Niu.

However, the other party has been here every day since the previous few days, but now it has been here once every next day.

Not only that, Lei Yi guessed that the further the training of Tienniu would become, the more wasteful it would be, and even Tienniu's cultivation would also have bottlenecks.

As for the reason, Lei Yi also knew, but he had no way to remind the other party, because it was really hard to say whether it was good or bad.

"Guru..."

His stomach made a strange cry, because his body urgently needed nutrients when practicing.

Lei Yi hurriedly set out to the cafeteria, and looked at the bracelet bound to his arm on the road. The progress of the training in the bronze skin realm above had reached 15%.

"This speed is still not fast enough!" he shook his head secretly.

I have been practicing in the gravity room for more than a week. After training every day, I will use body fluids when I go back.

But even so, Lei Yi's progress was only 15%. Although the physical defense power increased every day, the progress was still slow in his opinion.

If other students know, I don’t know how many people will despise him.

Because most students in the students make less than 1% of their daily progress when they break through the copper seed realm, and some students even do not make more than 50% of their progress in practicing for a whole year.

He was so happy that he increased by 15% in more than a week and was not satisfied. This is a typical example of not knowing how to be blessed.

"I don't know how far Iron Niu has been practicing. I heard that his body refining speed is comparable to many senior geniuses. With the assistance of the gravity room, the progress should be faster than mine, right?" Lei Yi guessed.

On the first floor of the canteen, when Lei Yi was about to step on the stairs, he actually saw the Tie Niu.

However, Tie Niu and Huang Keke were together at this moment, and the two were having a meal in the corner of the first floor hall of the cafeteria.

The two of them sat at each other, Huang Keke stuttering and Tie Niu feasted, but from time to time, they looked at Huang Keke with a fascinating look.

As the secretary of the student union, Huang Keke has a wealthy family, sweet appearance, and petite figure, which gives people a pitiful impression and can inspire others' desire to protect.

The combination of the two beauties and "wild beasts" also made the students who came and went to the cafeteria around them look at each other frequently.

"Since ancient times, heroes have been sad to pass the beauty!" Lei Yi complained in his heart, but he didn't meddle in other people's business.

Tieniu has been very close to the student union secretary Huang Keke recently, and this is also the reason why the other party abandoned the training.

Because of women, martial arts practice was abandoned.

After all, whether it is Lei Yi, Tie Niu, or girls such as Huang Keke, they are still eighteen or nineteen years old, and they are young.

Moreover, there are so many young students in the Martial Arts University of the Demon City, both men and women, and it is normal for them to fall in love with each other.

Lei Yi is not a Tieniu parent, so he naturally would not remind the other party not to fall in love, otherwise he would waste his studies and martial arts, etc.

This is thankless and may even get into trouble.

He no longer paid attention to Tie Niu, but walked straight to the third floor, and he naturally went to the old place.

In front of Lao Luo's stall, Lao Xing and others smiled and greeted Lei Yi.

"Oh, boy, the training has been completed, that thing has not broken down, right?" Zhao Blacksmith and Xuan Wuyan sat together and greeted with a smile.

Lei Yi knew what the other party was asking, so he calmly replied without any problem.

"When I came here just now, I saw that the boy of your same period seemed to be named Tie Niu, but he actually mingled with the little girl from the student union. Tsk, it's not okay!" Zhao Blacksmith said with a little contempt when he saw Lei Yi sitting down.

"That's someone else's business. Besides, haven't heroes been sad for beauty since ancient times?" Lei Yi spread his hands and said that there was no solution.

"This is, Wuyan and I were like you said back then. This hero has been sad to pass the beauty since ancient times!" Zhao Blacksmith nodded after hearing this and agreed.

"Save you, you're a hero, and you're almost the same as a bear!" Old Xing, who was beside him, sneered at him.

"What nonsense? That's because I feel sorry for Wuyan, so I just give in to her everywhere. Do you think it's right, my wife?" Zhao Blacksmith immediately retorted, and then asked Xuan Wuyan on the side for a flattering advice.

However, his request was useless, and Xuan Wuyan ignored him.

Zhao Blacksmith didn't feel embarrassed, and then sighed to Lei Yi: "What a pity that iron cow, I met someone wrong, Huang Keke was scheming at a glance, and she was ruthless in her falling flowers. She was afraid that she would be a licking dog at that time!"

Don’t underestimate dog licking, they also have dignity!

Although Lei Yi retorted in his heart, his face was expressionless.

"By the way, you kid seems to be close to several girls of your class, don't waste your martial arts because of women!" Zhao Blacksmith reminded again.

"What are you talking nonsense? They and I are just classmates!" Lei Yi solemnly stated.

"Hmph, I understand, we all understand!" Zhao Blacksmith immediately gave Lei Yi a look of "I understand you" and realized the meaning by yourself.

"Women, it's the most troublesome, right?" Old Xing took a sip of wine from the side and sighed quite emotion.

"After all, I loved you back then, but I was not like you, a bachelor!" Lao Luo sneered and retorted after hearing this.

"I have seen through it for a long time and know that women are in trouble, so I have lost this thought!" Old Xing drank all the things in the cup in one mouthful and said quite melancholy.

There is a story here!

Lei Yi was really curious. Although these "Four Freaks" seemed to be close friends with him, none of the four of them had disclosed their deeds back then.

He was also a little surprised. What experience made Old Xing Lao Luo so emotional, and also made Blacksmith Zhao so cowardly.

Even though he is curious, he will not deliberately inquire about these things.

Now he has a good relationship with the other four, and only fools will do those extra things.

After eating and drinking, Lei Yi returned to the living area and picked up all the books placed in the study, intending to take them to the training room to read.

Among these books, there is also a book called "Before and After the Copper Skin Realm Advancement" for yourself to check.

This book introduces some precautions for practicing the bronze skin realm. Lei Yi had Xuan Wuyan's teachings before, but he did not remember this book.

But recently he felt that his cultivation in the Copper Skin Realm was slow, so he remembered the existence of this book.

The book records that the copper skin realm is the most critical stage for practitioners to polish their body. During this stage, the burden of training needs to be gradually increased, so that the body can adapt to the cruel environment and achieve the goal of becoming stronger.

"The limit of the gravity chamber is ten times, how can it be broken?" Lei Yi looked at the records in the book and scratched his head.

At this moment, he saw A Liang passing by in front of him, and a flash of inspiration flashed in his mind and had an idea.

The gravity limit of the gravity chamber is ten times, but no one can say that gravity can be increased any more.
