"How? Something interesting, right? Yang Fei said with a smile.

"I tried a variety of materials, and each material had a different degree of sensitivity to internal forces, with metals being the most inductive, so I came up with this idea. You see, this is an iron nugget, which is stronger than other organic matter, but much weaker than other metals, and this gold nugget. I don't know if it's because of the weight, or if the sensing force is not enough, and it's also in a low place. ”

"On the contrary, this copper and silver nuggets have a stronger reaction, and under the same internal force, these two are the most intense reactions among commonly used metals."

Wu Liang and Duo'er both listened very carefully at this time, and Duo'er pointed to another pair of metals and asked, "What about these over here?" ”

Yang Fei smiled awkwardly: "I've confused these metals, and I can't recognize the type anymore... However, there is still a difference, there are still highs and lows. One of them is much stronger than copper and silver! ”

"What do you mean?" Wu Liang suddenly thought of something, and glanced at Yang Fei, his eyes full of excitement and excitement.

"If your guess is successful, then we can make a flying sword!" Wu Liang said.

Yang Fei nodded, the energy contained in the internal force is very amazing, which scientists have also studied, but there is no suitable way to release these energies, so there is no way to use it.

"Wait, that's not right." Wu Liang suddenly calmed down: "If it was discovered by you so easily, then how could those scientists not find it, I'm afraid that when the internal force was just accepted by everyone, scientists did all kinds of experiments." ”

"Yes..."Yang Fei frowned, and then said: "Maybe it's because the purity of the internal force at that time was not enough, if it is an evolutionary who can't even do the external manifestation of internal force, it is almost impossible to stimulate these metals, and the purity of my internal force is far purer than that of evolutionaries of the same level." ”

"Also, if it's a flying sword, how are you going to feed him with internal force? It can't be that you can only send it, you can't receive it! What do you rely on to control it? ”

Yang Fei was stunned for a moment and said, "It's very simple, you see." He spread his palms, and while maintaining the internal force output, the pieces of metal began to move, moving as he wished.

"I just have to think about how to make it move, and he can do it." Yang Fei thought about it for a long time and didn't come up with a reasonable explanation. These pieces of metal in the palm of his hand, after he entered the internal force, it was as if he had naturally gained the command to control this small thing.

"Is it divine consciousness?" Yang Fei said to himself, when he was exercising, he easily found two special places inside his body, the first was the dantian, where a large amount of internal force could be stored, and his internal force could also be refined there. As for the role of the eyebrows, he has never understood the essentials, and he always feels that the place has absorbed a lot of internal force, but there is no obvious change, only occasionally he feels that there is a feeling there...

The two discussed for a while, but did not come up with a relatively reliable answer, and finally decided to try again, they picked up the top few pieces of metal, found the safe zone again, and prepared to ask for more.

Soon, they got the materials they wanted, and the supervisor who managed the supplies in the security zone had a good impression of them.

The hardness of these metals is not high, Yang Fei directly pinched out a palm-sized small sword with his hand, and after fully inputting the internal force in the palm of his hand, he imagined that the sword would fly out quickly...

"Whoosh!"

The metal sword that was originally floating quietly in Yang Fei's palm quickly rushed out, piercing through a wall dozens of meters away, and then they didn't know how far they flew, because that wall blocked their view!

"Oops! It won't hurt anyone! Yang Fei shouted and quickly rushed over there.

Soon, Yang Fei breathed a sigh of relief, the flying sword penetrated through the two walls and inserted it into the wall of the third wall, while a young female nurse was looking at the small sword in front of her with a pale face, which was less than three centimeters away from herself, and her sweat was already covering her entire forehead...

“… You mean, you threw this sword? The female nurse's face turned pale and red, and her fear slowly turned to anger. Then he directly raised his fist and hit Yang Fei with his head and face...

Yang Fei was beaten with his head scurry, he was neither unable to beat this nurse, nor unable to escape, but too weak-hearted, his own experiment almost killed an innocent nurse, which made him embarrassed, so he could only protect his face and make the other party angry...

Wu Liang and Duo'er caught up, amused by the scene in front of them, a third-order evolutionary was chased and beaten by an ordinary survivor, and they didn't step forward to dissuade them, but watched them with relish on the side. It wasn't until the nurse was so tired and out of breath that she pointed at Yang Fei and shouted not to run that they stepped forward to persuade her, and the female nurse saw that there were many people around, so she gave up the desire to do it.

It took a long time for Yang Fei to get out, seeing that his two members were only laughing at him, he had a stupid silent nose, his head was really not majestic at all...

The three of them came to the outside of the safe zone and continued the test just now, although they were ridiculed, but the test was successful, and the flying sword flew out under his control, and the power was not small.

"Try again, this time slowly." Wu Liang said.

Yang Fei nodded, this time after he rushed through the internal force, he imagined the flying sword slowly flying, and then hovering around him.

Sure enough, while he was imagining, the flying sword slowly floated up, slowly flying around Yang Fei. The experiment was successful again, Wu Liang snatched the flying sword and said, "I'll try it." ”

After he slowly injected his internal force into it, Wu Liang also imagined that he wanted the flying sword to fly, but no matter how he imagined it, even if there were green tendons on his head, it would only make the flying sword fly a little bit, and he was so tired that he almost fainted...

The corners of Yang Fei's mouth twitched, and he couldn't stand it anymore. He easily controlled the flying sword and slowly flew in front of Duo'er, who was also very interested in this thing, and immediately grabbed it in his hand and played with it when he saw this.

After a while, Duo'er threw the flying sword out, and the flying sword returned to Duo'er's hand after going around outside, and then threw it out again, having a lot of fun. Wu Liang's face turned even darker when he watched from the sidelines, he was not as good as a child...

Yang Fei's exercises can nourish his divine sense, and he and Duo'er are the first two to cultivate, so their divine sense is stronger than others, and it is easier to control the flying sword than others. After a while, Duo'er was also covered in sweat, although she had enough sense, but her internal strength was far behind, she only played a few times and couldn't do it, she couldn't hold it anymore, and barely withdrew her hand.

Yang Fei smiled slightly and asked, "Duo'er, do you want to try flying?" ”

Duo'er's eyes lit up and she nodded heavily. Yang Fei took out more copper pieces, and this time made something like a skateboard, crooked, but barely formed. Duo'er stood up very consciously and looked at Yang Fei expectantly.

After being charged with internal force, Yang Fei imagined that the skateboard would float slowly, but the skateboard shook but did not float, Yang Fei worked harder to control, making his head full of green tendons, and the skateboard finally floated, and slowly came to the sky with Duo'er, although it was only a few meters high, but it did fly!
