After the atmosphere on the scene fell, Wanchanghe started projecting, and a three-dimensional virtual human body covered with the direction of meridians appeared. A blue light flowed out from the Dantian part and followed a special trajectory to move in the meridians.

Everyone could see at a glance that this was the direction of internal element operation of the flight technique, but compared with the old version of the flight technique, there were some subtle changes.

Suddenly, when the blue light ran into a certain meridian area, it skipped without warning, as if a complete movie was suddenly cut off in the exciting part of the plot, immediately causing many people to make a dissatisfied sound.

However, there are also many people who are calm. They guessed that the key to improving the efficacy of flight techniques in such a significant way is probably the change in the operation of meridians in this area.

However, there are several meridians in this area intertwined with complex branches and veins, so it is difficult to know what kind of trajectory can improve the effectiveness of flight techniques by just imagining.

Wan Changhe explained warmly: "I want to say sorry to everyone here, because the improvement results have not yet reached the time for public promotion, and the final stage of testing is underway. If there is no problem, the Flying Association will promote the new flight technology to all humans for free within two months..."

Wan Changhe's words made the scene quieter, and most people could understand Fei Xie's concerns. National promotion is extraordinary. If there is a problem with the martial arts like last time, it will undoubtedly damage Fei Xie's reputation.

Next, Wan Changhe briefly explained the basic principles and research process of the new flight technique. Many stories full of bitterness, difficulties and even sacrifices were told from him, which made many people who were originally excited because of higher-level flight techniques were in a heavy mood.

Ban Ming was not among them because his attention was completely attracted by a thrilling comment from Uncle Ghost in the spiritual world—

"Those who seek death, who create this improvement method are seeking death, and those who practice this technique are seeking death!" Uncle Ghost sneered repeatedly, with disdain on his face.

Ban Ming was startled and asked quickly: "Why did you say that? Is there any problem with this improvement method?"

"Of course there is a problem! There is a problem with the original version of Nanshan Liechuang. Now this kind of improvement is even more problematic, and it is a big problem!" Uncle Gui snorted: "You should still remember that after practicing the original flight technique for a long time, it will disrupt the stability of the magnetic elements in the body, damage cells and nerves, and become a huge shackle that warriors in the heavenly realm cannot break through..."

Ban Ming nodded secretly, and naturally he would not forget this.

Just as the essence of Taiyuan Gong is the primary spirit gathering array, the essence of flying techniques is actually the magnetic element array. Although the flight techniques created by Nan Shanlie make the body fly freely without gravity, it will invisibly harm the human body and cause hidden and undetectable magnetic element disorder.

Fortunately, although this damage will affect the breakthrough of the powerful people in the Heaven Realm, it will not cause a loss in life.

Although the human population is large, there are very few powerful people in the Heavenly Realm. Even if they find it difficult to break through the realm, they only think that it is because of their own talent or the recognized reason that "the higher the realm, the harder it is to break through" and will not think about flying techniques.

"I know what you said." Ban Ming asked in confusion: "But what are the big problems with this kind of improvement now? Hasn't Feixie conducted human tests for three years? If there is any problem, it should have been exposed now, right?"

Uncle Gui sneered: "If there is no problem for three years, it does not mean that there is no problem for five years. If there is no problem for five years, it does not mean that there is no problem for ten years! If this technique is implemented among all mankind, there will be big problems within ten years! At that time, the average life span of human beings will return to the level of five hundred years ago. Living ten years is considered longevity..."

Ban Ming was really scared this time, and finally understood why Uncle Gui said that practicing this new flight technique was a way to die. He quickly asked: "How could this happen? This new flight technique actually reduces life span? What's wrong with this technique?"

"Although the most critical part is incomplete, at least you were by chance to use the Tai Chi diagram to increase the flight technique by 30%. Your understanding of flight technique should surpass everyone in the world. You won't think about it yourself, what would the broken part be like?" Uncle Ghost asked without answering a question.

Ban Ming immediately frowned and thoughtful.

"Student Ban Ming, what's wrong with you? Do you think there is something wrong with this kind of improvement?" Yang Yaren, who was sitting on Ban Ming's right, suddenly asked in a low voice.

"Not necessarily..." Ban Ming said subconsciously, then noticed that the occasion was wrong, and smiled dryly at Yang Yaren, who showed a strange look in his eyes: "I just think it's incredible to improve the efficacy so much at once."

"Oh..." Yang Yaren nodded, but his eyes were skeptical. The woman's intuition made her feel that Ban Ming seemed to be hiding something.

Ban Ming's words fell into Wan Jiangshan's ears and felt that he had finally caught a chance to overtake Ban Ming. He immediately raised his eyebrows and snorted, saying, "It's really ignorant. So many experts who have studied flight techniques for life have not found any problems. After following the human body test for three years, he didn't find any problems. Ban Ming, you can actually see the problem by looking at the incomplete exercise diagram of the exercises, haha..."

When he finally "hehe", Wan Jiangshan shook his head, and the disdain and ridicule were undoubtedly revealed.

He did not lower his voice like Yang Yaren, and it could even be said that he deliberately raised his voice, which was enough to make the leaders of the school in the front row and even the other three cadres from the Feihui Association hear it clearly.

Sure enough, the few people sitting in the first row immediately heard this and looked in the direction where Wan Jiangshan and the four of them were.

The three cadres from the Flying Association all smiled gently when they saw Wan Jiangshan. Then they looked at Ban Ming and stopped paying attention.

Nothing else, just talking nonsense.

They have been following Wan Changhe to give lectures all year round, and they have long seen many sensational people.

Guo Zian also subconsciously glanced at Ban Ming, and a strange thing flashed deep in his eyes. Then he turned around like others, but he secretly kept his heart.

If anyone else said this, he would have thought Ban Ming was pretending to be crazy, but he was "Po Lao San" who said this, so he had to worry about it.

Just when Wan Jiangshan felt that he had hit Ban Ming in the face and was secretly proud, Yang Yaren said annoyedly, which directly hurt him internally—

"Wanjiangshan! You are not allowed to say that to my boyfriend!"

Ban Ming also wanted to vomit blood and sent a message: "When will I become your boyfriend?"

"Hey? So you can send a voice message to classmate Ban Ming. That's great. We can whisper." Yang Yaren's eyes lit up as if he had discovered a new world, and then he continued to send a voice message with a slightly distorted expression: "I'm sorry, I accidentally expressed my wish for a lifetime. Can I forgive me this time?"

My God! Such a wish will last for a lifetime. How come you feel like you are entangled by a resentful spirit? If you say that, I feel more and more stressed!

Ban Ming glanced at her speechlessly, and then felt like he was stared at by a sinister look.

Don't get me wrong, this sinister look is not from the mountains of the world, but from Xi Mengyan on the right.

So terrible! The pig woman who stares at the corners of her mouth but smiles so terrible!

Ban Ming sat upright, just as he was about to send a message to explain, but he found that Xi Mengyan suddenly turned around and his expression became a little sad.

Alas? Ban Ming was secretly surprised. Such a look was rarely seen on Xi Mengyan's face. Could it be because Yang Yaren called him "boyfriend"? With Xi Mengyan's wisdom, it would be impossible to tell the truth or the false?

Out of concern, Ban Ming still sent a message to ask a few questions, but did not get Xi Mengyan's response, so he had to give up.

There is a saying that you should not guess what a girl thinks. Ban Ming thought about it for a few seconds but didn't understand it, so he gave up and then continued to think about the new flying technique.

After pondering for a while, a bright color suddenly flashed in Ban Ming's eyes and said to Uncle Gui: "Is that so?"

Then he used verb description to complete the most important part of the exercises that Wan Changhe publicly announced, and then he wondered: "But if the flight technique is performed in this way, the improved effect should reach 10% instead of 5% as Wan Changhe said?"

"There is only one reason. The exercise diagram you completed is much more sophisticated than the latest achievements developed by Feihui."
Chapter completed!
