Opening the various skills on the necklace, even Ye Xiaofei used the Nar transformation skill, and all the muscles in his body swelled, and his strength soared.

When he came to that door, Ye Xiaofei planned to use violent means to forcibly open the door. With his current level of violence, let alone opening a door, even if he destroyed the entire underground base, it would be a breeze.

However, just when Ye Xiaofei's double doors buckled the edge of that door, something strange happened.

The eye on the door suddenly opened, and then a blue light flashed, Ye Xiaofei only felt that all the strength of his body was attracted by that door, and he couldn't exert any strength in his body.

Sitting on the floor gasping for air, the eye pattern closed again as his hands left the door, and everything was back to normal.

This...... What the hell is going on?

Ye Xiaofei stared at the door blankly, his eyes full of incredulity. That door was able to absorb the skills and powers he used, making it impossible to use all his abilities.

Seeing Ye Xiaofei sitting on the ground, Fei Fei and Xing also came around.

"Brother, what's wrong with you?" Star couldn't help but ask.

"This door won't open." When he saw the star, a flash of inspiration flashed in Ye Xiaofei's mind, and he wondered if the star could open this door after putting on the nano armor? "Star, you put on the nano armor and try it to see if you can open this door."

"Oh." After saying that, Xing clicked on the energy bracelet on his wrist.

The light flashed, and a biting chill hit him, and the surrounding area began to be covered with frost. At this time, Xing's body instantly had an extra piece of ice-blue armor, and he was holding an energy longbow in his hand.

Ye Xiaofei and Fei Fei dodged backwards at the same time, their eyes full of horror.

"Star, it's okay for you to wear nano armor, don't release ice nanoparticles." Fei Fei couldn't help but yell.

Fei Fei was really scared, the last time she was frostbitten, Ye Xiaofei used treatment to have a relationship with her, and she felt shy when she thought about the scene at that time. With the experience of the last time, Fei Fei didn't want this to happen a second time.

Of course, even if there is a second time, it doesn't matter.

These days in the hospital, Fei Fei has taught her a lot of techniques for using nano armor, but she can't get the star to control the release of nanoparticles. The main thing is that this armor is still very different from the nano armor developed by Dr. X, and the power of the nanoparticles released alone is terrifying.

Comparing the two nano armors, it is obvious that the performance of this nano armor on the star body is more superior. As for how good the combat performance is, it will have to be tested.

Put away the nanoparticles, and all the cold air condensed on that armor. Star slammed his fist into the metal door, and the moment the fist made contact with the door, a roar erupted.

Touch!

Ye Xiaofei felt that the whole room was trembling, as if it could collapse at any time. However, the eyes on the door were still open, and all the obscure runic marks on the door became shining.

The punch was powerful, but the door was so strong that there wasn't even a small scratch.

The punch he threw with all his strength didn't cause any damage, and Xing was not reconciled and continued to swing his fist.

It is worthy of nano armor, and the increase in the human body has reached a very terrifying level.

Boom Boom! ……

The metal door made a loud bang, and the entire underground base trembled, and no matter how hard the star tried, it couldn't open the door, not even a single scar.

"Stop, stop! Stop star, or we're going to collapse here! ”

Ye Xiaofei shouted loudly, and Xing stopped attacking.

The runic sigil on the door gradually dimmed, and finally returned to its original state.

It's so weird!

It seems that this door cannot be opened by brute force, and there must be another way. As for his necklace, Ye Xiaofei has never been able to fit into that eye, so he can only think of other ways. However, one thing Ye Xiaofei can be sure of is that when the star attacked, that dull sound proved that the back of this door was empty.

Yes, there's definitely room behind this door. As for how big it is, Ye Xiaofei doesn't know.

"Brother, this door is very strong." Xing also felt that her arms were sore, and the strong recoil force had a great impact on her body.

"Okay, let's go to the training base for training in a while, you can't do it here. If it collapses, we'll all be buried alive. ”

Ye Xiaofei took them to the gravity training room, and after various identification verifications, the heavy crystal door slowly opened.

Fifi and Star arrive at the gravity chamber and seem so curious about everything around them.

"Hey, hey, what's this place?" Fei Fei touched the wall and said.

"This is a special place to train nanofighters." Ye Xiaofei also learned about the situation from the explanation, as for what his parents did, he only knew some scratching the surface.

Anyway, this gravity room is very good for the training of the human body, and Ye Xiaofei feels that his physique has been significantly enhanced.

The voice input control system, at first 1.2 times the gravity, does not feel anything. Then Ye Xiaofei increased the gravity to 1.5 times, and at this time, Fei Fei's face was full of surprise.

It turns out that gravity can really be simulated here, but under the influence of this gravity, the restrictions on human activity are still very large.

Looking at the star again, it seemed that gravity had no effect on her at all, so Ye Xiaofei doubled the gravity.

Twice the force of gravity is a very big challenge for the human body.

After all, a body of more than 100 catties has become more than 200 catties here. The heart, sensory nerves, muscles, internal organs, brain, etc., can react very violently in the environment of gravity.

Especially the heart and brain, gravity makes all the blood concentrate on the lower half of the human body, Ye Xiaofei feels as if his heart is about to explode, his eyes are black, and his vision has become much blurred. The line of sight is affected, and the surrounding objects begin to become distorted.

Fei Fei sat directly on the ground, gasping for air.

He and Fei Fei were in great pain in the gravity environment, on the contrary, the star wearing the nano armor, gravity did not affect her much.

Unexpectedly, the nano armor still had this effect, and Ye Xiaofei admired his parents a lot.

The gravity system of the gravity chamber is turned off, and the gravity slowly decreases little by little. Fortunately, it didn't disappear instantly, otherwise Ye Xiaofei and Fei Fei would definitely die of a heart explosion.

Ye Xiaofei and Fei Fei were all lying on the ground, while Xing next to her was at a loss, she didn't know what was going on at all.

"This room is really interesting." Fei Fei coughed a few times and spat out a few turbid breaths.

"This is the gravity room, and you can simulate ten times the gravity. Exercising here can do more with less. Ye Xiaofei explained.
