Du Bixing secretly learned Wei Yuanhao's martial arts while accompanying him. Because of his correct practice, some of his mistakes could be corrected soon.

After one day, Du Bixing had mastered the skills of the Phantom Chain Kicks. Wei Yuanhao was also very satisfied. Although he spent tens of thousands of yuan in a sparring training fee today, his martial arts mastery has improved again.

"Look at the legs!" Wei Yuanhao used all his strength to kick Du Bixing like a storm. He was faster than the other, and stronger than the other. In conjunction with the use of the Force, his power was more than three times more powerful.

Du Bixing can't withstand it directly if he resists it. But this is a senior guide and can fight back. Du Bixing also uses the same move and fights back with his feet.

The general moves, but Du Bixing seems to be faster and stronger when used. This is all due to his copper and iron bones, which have strong bones and stronger force vibrations, so his strength increases.

Wei Yuanhao can only play one or three times, but Du Bixing can play one or five times the strength. Wei Yuanhao was kicked backwards by him and forced to the edge of the field.

Du Bixing kicked him in front of him, and Wei Yuanhao panicked: "Stop!"

Du Bixing's body tilted and kicked into the empty space.

"So amazing!" Wei Yuanhao said in surprise, "Just just a training student, he is better than me. Are you a strong man in Wuzong? At least you are a high-level person!"

Du Bixing did not answer his question, but instead changed his voice and said, "Are you going to come?"

"I won't come today, I will continue tomorrow!" Wei Yuanhao didn't forget to shout before leaving.

Du Bixing just nodded and did not answer. After going back, he asked the ball girl to count all the data of today's battle and analyze it.

"Master, based on your description and analysis of the battle scenes, I have compiled the first version of the martial arts "Phantom Serial Kick". "The Ball Girl directly generated the martial arts secrets.

This is an e-book with action demonstrations and move explanations.

Du Bixing looked through it and there was probably no problem. He asked, "What level is this?"

"It is a martial arts secret at the level of the high-level original warrior." said the girl, "I checked it. There is a secret book for "Phantom Serial Kick" sold online, but that level is at the level of the high-level Wuzong."

Du Bixing's eyes lit up and he said, "So, can we sell this secret book? Ball girl, please check if there are any legal issues."

Du Bixing studied in high school. The Tang Dynasty's Knowledge Protection Law stipulates that once a secret book is applied for a knowledge patent, it cannot be sold pirated. Otherwise, the punishment will be very serious. Many strong people have to sell secret books they created. They are powerful, so few people dare to do it in terms of piracy.

Even if it is really pirated, it will not spread widely on the virtual network.

Furthermore, if you want to pirate the product, you have to be at that level. It takes a long time for ordinary original warriors to learn martial arts, let alone create one by themselves! If they create a garbage martial arts that no one wants to buy, it will be even more embarrassing, and pirated products will lose money.

The Ball Girl searched on the virtual network, and after a moment, it said: "Master, based on the laws and regulations I found and the actual cases. Martial arts secrets with similarity below 80% are qualified to be sold, and the similarity of our secrets is less than 80%.

When a martial arts appear, many similar martial arts will definitely appear. Some are improved versions, and some are imitating and following the trend. This is often the case on the Internet, but most of them follow the trend and imitate the famous martial arts secrets because the ones are easier to sell.

Some martial arts that follow the trend and imitate are even made by the original creators themselves, just to make more money.

This "Phantom Serial Kick" is just an ordinary martial art, and strictly speaking, it is also a martial art that imitates a more advanced leg technique. Therefore, there is no problem in Du Bixing selling his low-end version of "Phantom Serial Kick".

"Okay, help me to authenticate the patent online, and then sell it on the Hunter Alliance Mall!" Du Bixing said happily. Unexpectedly, as a sparring practitioner, he could find such a way to make money. This low-level martial art can be sold for hundreds of thousands of yuan as long as the certification is successful! And it can be sold repeatedly, which is simply a huge profit.

At the same time, Du Bixing also placed the B1 cell enhancement liquid that the college rewarded before and sold online. This thing has limited effect on him, so it is better to sell it directly.

The Hunter Alliance Mall priced at 299,000 federal coins. As long as it is sold and taxes and commissions are deducted, he can still get more than 2 million, which is another income.

Two days later, the patent application was approved. Du Bixing's low-end version of martial arts, "Fanying Serial Kick" was qualified to be sold.

However, there is still a procedure for sale, which is to pay for martial arts data and practical videos for reference by buyers, otherwise no one would buy a "three-no" martial arts.

Du Bixing first went to the professional martial arts testing room of Taizhou University to record a piece, which was to compare the power and speed in various aspects such as before and after the display.

Then, there are also practical videos. This is a bit difficult to record. If you want to sell a martial arts secret, you must have wonderful practical videos. The secrets that are popular on the virtual network are like this.

At this moment, Du Bixing received a copy of the challenge book in his school mailbox!

It was a challenge from Wei Yuanhao. He decided to clean up his shame before the official assessment of the Taizhou Association so as not to affect the participation in the association.

In the dormitory, two roommates also learned about this because Wei Yuanhao directly hanged the challenge book on the school forum.

"Brother Du, look, Wei Yuanhao sent you a challenge letter with his real name on the school forum, and he was very arrogant!" Qi Ming shouted to Du Bixing.

Du Bixing took a look and said that his words were very arrogant. On the forum, this guy didn't mention the previous father-son situation. Anyway, he just made a big fuss and wanted to deal with Du Bixing.

"This guy is not giving up and wants to call him back?" Qi Ming snorted, "I didn't beat him enough last time by Brother Du!"

Zhu Ping'an said cautiously: "I just checked it, and Wei Yuanhao's strength seems to have improved a lot. This time, he ranks eighth in the Fighting Academy's freshman assessment! Brother Du, don't take the battle, you have never practiced martial arts. In this regard, the students in their Fighting Academy have the advantage!"

Qi Ming thought, and said, "That's right. The school says that before the strength of Wuzong, the fighting academy is the strongest. After Wuzong, Zhenwu Academy and Taibai Academy can only make a comeback. This kid may have learned some martial arts. Don't pay attention to him this time, so he won't fall."

Du Bixing smiled confidently and said, "It's nothing to take the move, it's just too unchallenging."
