Walking down the underground passage, it suddenly became clear to me that two more halls, two halls side by side, appeared.

At this time, Ye Xiaofei felt that he was already more than fifty meters deep from the ground, but he didn't expect that there was such a large space down there. As for when it was built, Ye Xiaofei never knew.

The two halls are completely transparent, made entirely of sky-blue glass. Ye Xiaofei walked forward and found that the glass was twenty centimeters thick, and judging from the feel, this was not ordinary glass.

When Ye Xiaofei's hand touched the glass door, various symbols appeared on the side of the door, and finally converged into the shape of the Eye of Horus. Those eyes seemed to be moving, looking down at Ye Xiaofei.

At this moment, the sound of electrons rang in my ears.

Didi ...... Scanning for visitor permissions...... Please wait.

After about five minutes, the Eye of Horus lit up, and the electronic sound sounded again.

Didi ...... The visitor's permission has been determined, the name is Ye Xiaofei, the DNA verification is successful, the retina verification is successful, the facial scan verification is successful, the fingerprint verification is successful, the permission is obtained, and you can enter.

At this time, the door slowly opened, and Ye Xiaofei felt a heat coming from inside.

A row of typography appeared on the door, and the electronic sound was still ringing.

Didi ...... Please read the tips carefully before entering the training room.

Ye Xiaofei saw the words on the door, and when it was the most eye-catching line, the big word - Nano Warrior Training Room.

Below are a variety of training methods, all about nano warriors. Ye Xiaofei was also a little incomprehensible, so he had to take out two pieces of jewelry with intelligence to wear, and suddenly his brain memory became much stronger, and he also became clear.

Looking at those words, Ye Xiaofei understood, it turned out that this was the human training hall for nano warriors, and it was also the nano warriors he had met before. It's just that they are all wearing armor, and this is just training for the human body.

There are thousands of strange training methods, but the requirements are very demanding, and before you want to become a nano warrior, you must train rigorously here.

After having the intelligence bonus, Ye Xiaofei had the ability to remember within 20 minutes, and he recorded all the training methods on the side. His physical fitness is too poor, and every time he uses the skills in the necklace, he will have a strong energy backlash. If the body is stronger, those energy backlashes will weaken or even disappear.

No wonder this is the case, with an excited smile on the corner of Ye Xiaofei's mouth, he finally found a solution. However, he doesn't want to be a nano warrior, even if he can strengthen his body, it is also very good to train his body to be stronger.

According to the prompts of the instructions, Ye Xiaofei entered the room, and at this time, the heavy glass door actually closed by itself.

There was blue transparent glass all around, and when the light lit up, Ye Xiaofei found himself in the universe, with the blue earth in front of him, and the atmosphere was so pure. Not far away is the moon, and the sun in the distance looks like a giant fireball. The trajectories of every planet in the solar system can be seen clearly, not far from the vast Milky Way.

When Ye Xiaofei stood here, he would feel that as a human being, no matter how powerful he was, he would seem very small here. And the earth is just one of trillions of planets, just a grain of sand in the desert.

Didi ...... Name Ye Xiaofei, physical condition evaluation grade D, it is recommended to use the primary training method.

The explanation has been introduced, the system here will arrange reasonable training methods according to everyone's body structure and physical fitness, Ye Xiaofei's current physical state is D-level, and it is also the body of ordinary people, and he can only do some of the simplest training. There are also C, B, A, and S grades. Only those who have reached the level of physical fitness can carry out the physical training of nano warriors.

Step by step, you must start from the basics, if you don't learn to walk and want to run, you will often fall worse.

Didi ...... Do you want to start beginner training?

When the electronic audio started, Ye Xiaofei chose to be sure.

Didi ...... The 1.2x gravity system is on, please follow the prompts to train.

Suddenly felt his body sink down, Ye Xiaofei felt that his eyes were black, and his breathing became heavy.

The Gravity Lab is the most basic training base for nano-warriors, and the gravity can be increased from 1.2 times to 10 times. Of course, when ordinary people are subjected to twice the force of gravity, their physical abilities simply cannot withstand it. The first is the heart, after all, people are standing, and the strengthening of gravity will affect blood circulation and directly affect the heart.

All organs are the same, and all organs will be affected. However, according to the manual, if you want to become a nano warrior, you must train through the triple gravity experiment. That's right, it's three times, it's also a hundred catties, and it's three hundred catties here, and the difficulty can be imagined.

Now it's only 1.2 times the gravity training, Ye Xiaofei feels that his eyes are black, and his whole body has become very uncomfortable. Not only that, but it also becomes much more difficult when exercising. Even when I walk, I feel like I'm about to lose my balance.

The primary training is simple, starting with a ten-minute jog, followed by ten push-ups, and then a workout of various training equipment.

These exercises are easy in a normal environment, but at 1.2 times the gravity, they become very difficult. After only two minutes of jogging, Ye Xiaofei's forehead was covered with beads of sweat, and his vest was also soaked with sweat. After ten minutes, I was sweating profusely, and I was so tired that I couldn't breathe. Originally, Ye Xiaofei's usual exercise was very small, but now that he has suddenly strengthened, he will inevitably be a little uncomfortable.

He would love to train in gear that adds agility or strength, but that doesn't serve the purpose of training.

After the jog, the next step is a push-up. Doing ten push-ups is a piece of cake at all, but in the case of gravity, Ye Xiaofei felt that his joints were rubbing violently, and his muscles were twitching.

Beads of sweat slid down his cheeks and fell to the ground directly into small droplets, and there was not even a splash of water, which shows that gravity still has a very large impact on the surrounding environment.

After ten push-ups were done, Ye Xiaofei lay on the ground, only having the ability to gasp for air. Look at the training facilities next to it, but what he did just now was just a warm-up for him, and the real devil training was still to come.

Two hours later, Ye Xiaofei almost crawled out of the gravity training room, his whole body was soaked with sweat, as if he had fallen into a pool. And it was the system that forcibly terminated his training, fearing that his body would be injured.

It seems that you have to come here often in order to improve your physical fitness......
