Before going home, Xu Fei used Yuan Li to cure the bruises on his body, so as not to worry his parents, this is also the benefit of having Yuan Li, which can quickly heal some injuries, of course, Xu Fei's own cell activity is extremely strong, but Xu Fei's healing speed still surprised Lin Ziyi.

After returning home, after eating and taking a bath, Xu Fei and Lin Ziyi went out when Xu Xueqing quietly followed.

There were a lot of mosquitoes outside, and Xu Fei felt a little sorry for his sister, so he made a telekinesis shield for his sister and spread it all around his body. Seeing that Xu Xueqing was a little squirming, she asked, "What's the matter?" ”

Xu Xueqing blinked, hugged Lin Ziyi, and begged, "Can I go to training with you?" ”

Today, Xu Xueqing was not lightly angered by Xu Li's lofty attitude, and after she knew that Lin Ziyi was a martial artist in the Three Seas Realm, she longed for it, so she made up her mind to practice boxing well, become a martial artist in the future, and teach Xu Li a good lesson. She saw that Lin Ziyi gave Xu Fei special training, so she also wanted to follow the practice.

"Why are you so positive today?" Xu Fei said with a smile.

Xu Xueqing said angrily: "What do you mean to be so positive today, I was very positive before, okay?" ”

"Really?" Xu Fei quipped: "Someone hasn't fought the seventh set of basic boxing techniques a few times." ”

Xu Xueqing said angrily: "Who wants to learn from you, I want to learn from Sister Lin." ”

Xu Fei looked at Lin Ziyi, now Lin Ziyi is helping himself with special training, is it too troublesome to add Xu Xueqing's words?

Lin Ziyi didn't feel embarrassed, and when he saw Xu Fei's expression, he knew his thoughts, so he said, "Yes, anyway, there is no special training tonight." ”

Xu Xueqing was immediately overjoyed, went back to say hello to her parents, and happily followed Xu Fei and Lin Ziyi.

The moon stars are scarce, the breeze is coming, except for the mosquitoes are a little annoying, the outside world is still very cool, Xu Fei pondered his battle with Lin Ziyi today as he walked.

"I have exerted my full strength in today's battle with Coach Lin, although it is very enjoyable, but when I think about it, there are many shortcomings."

Xu Fei was not calm enough because of the influence of evil qi, and he began to burn Yuan Force after a few moves, and his pursuit broke out, although the attack was very strong, but it was resolved one by one. And he didn't know the details of Coach Lin, as soon as he made a move, he stupidly used all his strength to defeat the strong, if he faced a weak opponent, this brave style of play might still be able to win, but once he met an opponent who was similar to him, he would definitely lose.

After thinking carefully for a moment, Xu Fei said secretly: "I have been fighting with fierce beasts for a long time, and I have more experience fighting with fierce beasts than many people, but if I fight with human warriors, I still have too little experience. Because beasts and humans are completely different, fierce beasts generally rely on their bodies, their own obvious advantages and disadvantages, focus on attacking for shortcomings, and then be careful to prevent the other party from dying to counterattack is almost able to take down the beast, but human beings are different, from the outside, people are almost no obvious shortcomings, can only detect the weaknesses of the other party in the fight, the most important thing is that people will collect information to develop strategies, if the level is not too exaggerated, powerful warriors will also be defeated in the hands of ordinary warriors. ”

Xu Fei secretly warned himself that in the subsequent battles, he must be cautious and not fight with human warriors like fighting fierce beasts.

Under the broken bridge, before Xu Fei could speak, Lin Ziyi said: "There is no special training tonight, just to let you recover your physical strength and spirit." ”

Xu Fei has been mentally contaminated with some evil qi in the past two days, these evil qi will affect his mind, although he has vented it, but he still needs to rest well, and he can't make his spirit collapse too tightly, otherwise he will be imperceptibly affected by the evil qi.

Lin Ziyi knew that these evil qi were all accumulated by Xu Fei's killing beasts, and they were all hidden in his self-consciousness, and only after truly controlling his spiritual consciousness could he not be afraid of the influence of these evil qi, of course, controlling his spiritual consciousness was only on behalf of himself, if there was a stronger spiritual power, it would still affect his spirit.

After the confession, Lin Ziyi began to teach Xu Xueqing soft boxing.

Xu Fei took a deep breath and began to play "Furnace Fist", but because he had been promoted to the Huiyuan realm, the absorption and refining speed of the energy particles of the Furnace Fist were not enough for him to absorb by himself, so he turned the "Silver Core" to use the ability to purify energy, and then used his spiritual power to construct the first section of the secret pattern on his body.

Call.

The wind rose, and a large number of energy particles in the void began to surge towards Xu Fei's place, forming a tornado-shaped energy vortex around Xu Fei, and began to quickly tear the energy particles around it towards Xu Fei's place, but this weather is not as vast as Xu Fei's weather in Wudang Mountain, because Xu Fei simplified this secret pattern a lot.

The secret patterns on the five sections are very complex, and Xu Fei finally found some clues after studying the secret patterns for nearly a year, any single secret pattern above these five sections can be simplified, and the simplification standard is that the big circle can not be wrong, and the lines of the main body construction can not be less, but the other smaller texture links can be simplified, and the degree of simplification corresponds to the strength of the secret pattern's ability.

But even so, it shocked Lin Ziyi, she knew that even if she practiced the Furnace Fist to the fourth realm, it would be impossible to absorb energy so quickly.

Frowning, Lin Ziyi said loudly: "Stop!" ”

Xu Fei was a little puzzled, but he still stopped and asked, "What's wrong?" ”

Lin Ziyi took out a thumb-sized stone from his waist pocket and threw it to Xu Fei, saying, "You don't have to make such a big noise, it will make people with a heart find out that holding this stone when you fight the furnace fist will naturally have a miraculous effect." ”

Xu Fei had no choice but to do so, turned off the function of the "silver core", held the small stone he had just taken and started the furnace fist, and with a dozen of the furnace fists, the stones in the palm of his hand drilled into Xu Fei's body from the palm of his hand, the energy level was extremely high, extremely pure, and only a little refining was needed to transform it into yuan force.

Xu Fei stopped in surprise: "The energy particles I absorbed with such a big momentum just now are not as good as a stream of energy in this stone, what is this stone?" ”

"Xuanjing!"

Lin Ziyi took the initiative to explain, opening Xu Fei's eyes to this ignorant person: "At present, the energy particles on the earth are all products of the explosion of basmarine, which is extremely violent, and the energy of the baitelite itself is extremely pure and stable, and the energy level is also very high, which can not only be used as energy, but also for cultivation." That small piece of syllabite I just gave you could give five families a year's worth of energy. ”

It was the first time Xu Fei heard that the Xuanjing Stone could still be used like this, but then it suddenly dawned on him, indeed as Lin Ziyi said, the energy particles on the earth are all the products of the Xuanjing Stone after the explosion for the martial artist to absorb, so this Xuanjing Stone itself must also be able to be used to cultivate Yuan Force.

"Is this spar expensive?" Xu Fei asked.

"In the Martial Alliance, that spar is hard currency, and the sylvestite in your hand is worth about four or five hundred thousand." Lin Ziyi said.

"Four or five hundred thousand?" Xu Xueqing smashed her mouth in shock, her face full of incredulity.

Xu Fei sensed it carefully, the energy in this Xuanjing Stone was indeed thick, but it was not as much as he imagined, it was about about four times the Yuan Power stored in a single acupoint in his body, once it was absorbed, this Xuanjing Stone would only turn into an ordinary stone, and it would take hundreds of years to recover.

"In the future, the syllabite will become more and more expensive." Lin Ziyi said: "So now in addition to the main energy source, the major base cities also have secondary energy systems, that is, the protective cover over the base city is used to condense solar energy to generate electricity. Because there will be less and less bassarite that can be used in the future. ”

Hearing Lin Ziyi say this, Xu Fei's heart moved, and the thoughts that were originally sealed in the depths of his heart came out again, and he said with some excitement: "Coach Lin, I have an idea." ”

Lin Ziyi originally had questions to ask Xu Fei, such as how Xu Fei pulled the energy particles in the nearby void just now, but at this time, Xu Fei seemed to have something very important to say, so he suppressed the doubts in his heart.

"Coach Lin, I got a treasure when I was in Wudang Mountain." Xu Fei took the "silver core" from his neck and handed it to Lin Ziyi.

Lin Ziyi took over the "Silver Core", she reached the Three Seas Realm, her physical fitness is very strong, and her night vision ability is also good, she can see the lines on the "Silver Core" clearly, and after carefully observing for a while, she has nothing to gain, but she feels that this "Silver Core" is different.

"I don't recognize this, what's the function?" Lin Ziyi returned the "silver core" to Xu Fei.

Xu Fei took the "silver core" and said: "This silver core itself has two functions, the first is energy filtration. ”

Xu Fei turned the "silver core", and the silver core suddenly glowed with brilliance, and a thin milky white light film centered on the "silver core" spread out at a distance of about three meters, and any energy that entered the scope of the light film became very pure.

Lin Ziyi was not as short-sighted as Xiong Hei, and instantly realized the preciousness of this thing, forcibly suppressed the shock in his heart, and said, "Can you know its principle?" ”

"That's exactly what I'm saying. I've figured out how this works. Xu Fei said excitedly: "There are five knots on this 'silver core', which correspond to five complete secret patterns, and these secret patterns can be connected, when I sketched the first secret pattern, I discovered an ability of this secret pattern." That's absorbing energy, and when I sketched out the first and second secret patterns, I found that they could combine to purify energy. Coach Lin, I've been thinking about it, if you can combine the two secret patterns, then will you be able to solve the energy crisis? ”

Lin Ziyi's body shook, and a colorless and transparent yuan force spread out, enveloping the distance of ten meters around, and he looked at Xu Fei with an extremely serious expression, with an incredible look in his eyes: "Xu Fei, you have made a very, very remarkable thing, even I have to be impressed by you." ”

Xu Fei was stunned and smiled: "Coach Lin said so, it seems that this is indeed very important!" ”

Lin Ziyi nodded: "Well, it's very important, if you're not careful, it may lead to the destruction of your family, and even cause a world war." ”

"A broken family? World war? ”

Xu Fei and Xu Xueqing were taken aback.

If Xu Fei didn't know Lin Ziyi, he would definitely think she was joking, took a deep breath, and Xu Fei said: "No, this is just a method of energy absorption and conversion, as for causing a world war?" ”

Lin Ziyi sighed in his heart Xu Fei's innocence, and fortunately met her, if he changed someone, I am afraid that Xu Fei would be arrested immediately and asked Xu Fei this method, if Xu Fei announced this method, I am afraid that I don't know how many foreign powerhouses will come to arrest him, and those who shoot must be martial artists at the level of titled powerhouses, the biggest possibility is that on the first day it will be announced, and there will be martial artists to arrest him on the same day.

"Xu Fei, don't you understand?" Lin Ziyi said: "The energy particles in this void were produced by the explosion of the sylvestite more than a hundred years ago, when the reserves of the syllabite were difficult to calculate, almost enveloping the entire earth, they exploded and filled the earth with endless energy particles, and the human race has almost no utilization of the energy particles in this void for more than a hundred years, and can only use the martial arts developed by the body to draw a little to refine, and because of its violent nature, it is almost impossible to use it industrially." And your method is equivalent to telling the world that you have discovered a new energy source with high purity and high utilization rate that is almost inexhaustible. What does that mean when you think about it? ”

"New energy." Xu Fei fell into deep thought.

Lin Ziyi said: "This new energy is enough to change the world, any individual, organization or even country wants this method, because it brings endless benefits, think about the oil one hundred and two hundred years ago, how many people died for this energy?" How many wars have there been? And what you find now is more than oil as an energy source, I don't know how many times. Do you still think it's impossible to cause a world-class war? And I'm very sure that as soon as you release it, I'm afraid that if you don't wait for the strong people of other countries to arrest you, some of our titled powerhouses in Huaxia will probably take action. ”

Xu Fei and Xu Xueqing were sweating profusely when they listened. The history of more than 100 years ago Xu Fei also knew very well that for the sake of oil, some major countries did not hesitate to plunder resources and even start wars. This kind of war of plundering resources lasted for a hundred years in some small countries, until the discovery of the bastile mine, and several large countries at that time were also ready to compete for the basmarine mine, but later it was found that the balite mine almost enveloped the entire earth, that is to say, everyone had a share, so there was no war, but now? Although the new energy is not as good as the direct use of baite, the current bastile mine will be used up sooner or later, but the energy particles in this void are almost endless.

Xu Fei didn't expect this method to be so important, but history told him that what Lin Ziyi said was likely to come true, and now he was not excited in his heart, and some were just apprehensive.

"So what now?" Xu Fei asked.

Lin Ziyi looked at Xu Fei's eyes and asked, "Do you believe me?" ”
