At noon, the base training site.

"Can you improve your strength here?" Under the leadership of the two, Luo Yun walked in front of a circular building, all white, without any other decoration, not even windows, only a circular hole in the center, this hole was completely sealed by a metal, and it was completely impossible to see the shape inside. This should be a door as there is a combination lock on it.

Luo Yun was a little puzzled, in such a strange small room, what could he do to improve his strength.

"This is the gravity chamber, and you can train with any gravity up to 100 times." Number Two replied simply and clearly.

"Gravity chamber?" Luo Yun instantly thought of the gravity setting of the mecha, and now he had broken through to twice the gravity, and his body was more flexible and stronger than before. The next step is to triple the goal. As No. 2 said, this should be the place to cultivate his gravity multiple, and Luo Yun began to look forward to it.

"Please come in with me."

"Drip ...... Passage is permitted. Luo Yun followed No. 2 in.

Inside the room is a confined space, as it appears from the outside, it is also a circular structure, only the floor is flat. The dome is made of glass, like a huge movie screen, and it looks very high-end. In the very center of the room, there are some utensils.

Treadmills, electric bicycles, barbells, presses, chest presses, and all kinds of fitness equipment are available, just like a gym.

"This is the controller, you can control the gravity in this room. If you have anything, you can use it to call me, and I'll go out first. At this time, No. 2 handed Luo Yun a rectangular remote control, and then turned around and went out.

"How do you use it?" This remote control has only three keys, a plus and a minus, and one without marking.

"Drip." Number Two didn't tell him the method to use, Luo Yun had to study it himself, and he tried to press a plus key.

"Activate double gravity." A mechanical voice came into Luo Yun's ears from a certain part of the room. Immediately after that, Luo Yun's body began to become heavy, but it didn't have much impact on him.

"Double gravity?" Luo Yun instantly understood that this plus key was to increase the gravity of the room, it should be double the gravity at this time, he didn't feel any discomfort, he had long been used to double gravity.

"Activate triple gravity." Luo Yun pressed the plus sign again, and the training of double gravity could no longer satisfy him now, so he chose three times.

Suddenly, a huge force was exerted on his body, and he was almost out of breath, but he was not as embarrassed as the first time, and was crushed to the ground.

"Uh... Barely able to move. After the battle with the wild boar and the brother Weisan, Luo Yun's body seems to be more powerful, and the three times the gravity can barely cope with it.

Straddling his heavy body, he began to walk up and down the room, a little reluctantly, but he had to grit his teeth and persevere. This is only three times the gravity, and the road is still long, four times the gravity, five times the gravity, six times the gravity...... Until that is a hundred times more out of reach. How could I give up so soon after I started?

"Tick... After a while, beads of sweat the size of beans continued to fall from Luo Yun's forehead to the ground. However, he did not stop to rest, but continued to do the circular movement.

"Come on, I can do it, come on." Luo Yun kept encouraging himself, constantly wanting to break through the current shackles.

Before he knew it, his body was getting stronger and stronger, and the muscles in his limbs and body began to slowly expand, becoming more powerful than before. It's just that he didn't notice this change, but he still kept trying.

"Ah......" Finally, at a certain moment, Luo Yun broke free from the shackles of triple gravity, and his whole body became less oppressive, and slowly returned to the behavior of a normal person. At this time, he became a first-class mecha master. Of course, he is a wandering mech master who is not recognized by the Mecha Alliance.

The level assessment of the mecha division is closely related to the gravity multiple that the individual breaks through, and the gravity of 1 to 3 times corresponds to the first class C mecha division to the first class A, and each double increases means that the level of the mecha master will increase by one level. 4 to 6 times corresponds to the second grade C to the second grade C, and so on.

When the third level is promoted to the fourth level, it is a watershed, and it takes twice the gravity to increase the level by one level. 11 times the gravity to 15 times the gravity corresponds to the fourth level C mecha division to the fourth class A. 17x gravity to 21x gravity corresponds to the three levels of a Level 5 Mecha Division.

Then when it comes to the time between level five and six, it is another watershed, and it is necessary to increase gravity by three times to break through the level of the mechmaster. 24 times the gravity to 30 times the gravity naturally corresponds to the three levels of the sixth-level mecha division.

After that, the gravity multiple of the seventh-level mecha master to the ninth-level mecha master, he didn't have time to ask Muhai, but for him now, it was a very distant thing, so it was better to improve his strength first.

"It's finally broken through three times, it's a lot easier, huhu." Luo Yun, who had just broken through three times, was a little excited, and he was relieved at this time. But after a lot of exercise, his whole body was already soaked with sweat.

"Boy, why are you doing so hard, be careful that it's counterproductive." At this time, the old man also came to the gravity room. Seeing Luo Yun practicing so hard, he couldn't help but feel a little relieved, but also a little worried.

"Uncle Long, are you here?" Luo Yun gasped and sat on the gym equipment next to him.

"In the future, like Qingqing, call me grandpa. If you call me Uncle Long, wouldn't you be a generation younger than the old man in Muhai. "The old man and Muhai are good brothers, but we can't mess with the seniority between them.

"Okay, grandpa."

"Let's go, it's time for dinner."

"It's dinner time, but I'm a little hungry." The time in cultivation seemed to pass very quickly, and in the blink of an eye, it was already night, Luo Yun touched his stomach, and he was indeed already cooing.

"Hmph, it's already past ten o'clock, I came to call you before you came back."

"What? So late? Then let's go back quickly, grandpa. ”

"Hmph."
