Time passed very quickly. In these three days time, Lin Feng was training the bladed member to the maximum, strengthening their grasp of the main points of training.

This kind of cultivation technique was very strange. One would lie flat on the ground and then breathe according to a certain pattern. The mouth would be tight and one could clearly see the agitation of the cheeks and the rise and fall of the chest.

The ups and downs were completely irregular, sometimes hurried, sometimes slow, sometimes continuous, sometimes short.

"Northern Nether Qi Refining Art."

The bladed member s were all over twenty years old. At this age, ordinary cultivation techniques could no longer be used, and the top cultivation techniques definitely could not be leaked. Thus, this kind of special cultivation technique, after being castrated, with a limit, was the best choice.

The Northern Nether Qi Refining Art was one of the best.

"Nine Styles of Darknorth."

"The first three stances."

There was also a set of battle skills that helped the North Nether Cultivation Method, Lin Feng cut out the first three forms and passed them to the members of Sharp Blades.

When the battle skill and the cultivation technique were combined together like this, bladed member's battle power would increase by leaps and bounds when compared to when she practiced to the small success stage of inner strength.

"Elder Xu, I have already given you the recipe for the cultivation technique and the medicinal wine."

"In three days, they have already grasped the essence of the cultivation technique. Next, you only need to make them persevere in their training, plus the medicine and wine, after three months, they will become martial artists at the initial stage of inner strength."

"In addition, with the three styles of the northern battle techniques, not to mention the martial arts competition in the five main combat zones of our country, even in the entire world, it is still possible to be the strongest among all the special forces."

After three days, all the members with sharp blades had mastered the essence of their cultivation technique. At this time, Lin Feng bid his farewell to Xu Changgeng.

It had been four days. It was time to go back.

More importantly, he still had matters to settle with the school. Three days had already passed since the arranged battle at Dan Tian Ya. He didn't know what had happened in the school in these three days.

Right now, he had to hurry back as soon as possible. He could not stay here any longer, or else, with his personality, he would definitely shift his anger onto Zhou Qiang and the others. He absolutely did not want to see this.

"Alright, no problem."

"Xiao Lin, don't worry. I will definitely monitor the requirements strictly."

Xu Changgeng did not ask his to stay. He knew that wanting a Martial Arts Grandmaster to stay here forever was an impossible task.

Moreover, ever since he had obtained the method and the recipe, there was only one thought on his mind. Three months later, when Sharp Blades left, he would report to his superiors and strive to promote this training in the army.

Minor Accomplishment of inner strength … If it could be promoted throughout the army, then countless soldiers at the initial stage of inner strength would be created. At that time, Chinese soldiers would be invincible.

"Elder Xu, don't think too much into it. If you want to cultivate my technique, the quality of the members of Sharp Blades Special Warring Group will be the key to its entrance."

Lin Feng continued, he had already seen through Xu Changgeng's thoughts.

It was impossible for him to achieve such a thought. Thus, it would be best for him to just open his mouth to break it.

"I see!" Xu Changgeng nodded in a rather disappointed manner.

Originally, he had wanted to promote the art of making medicinal wine and cultivating techniques in the army. If he could turn all the officers in the army into martial artists with low inner strength, then the army's overall strength would be a huge leap forward.

For soldiers like Sharp Blades, there were barely over a hundred soldiers in the entire Southern Hunan. Even in the entire large war zone of the south, there were only less than 700 people.

Compared to the country's 1.3 billion population, it was less than one in ten thousand.

"Elder Xu, you don't have to feel disappointed. inner strength warrior is very strong, even if it's just initial stage of inner strength, compared to a lot of people, it's still a giant existence. Their numbers can't be that high, otherwise, this world would be in chaos."

Lin Feng said with a faint smile.

"In the world of ordinary people, martial artists with small inner strength are already the tyrants of cities. What if millions of soldiers are all trained to be martial artists with small inner strength, then what happens after a lot of people retire?"

"All in the army? This is simply impossible. A small team of over three thousand is not a problem. "

General Xu was dazed for a moment when he heard this, but quickly recovered from his disappointment:

"Xiao Lin, you are right, this old man is too greedy!"

Lin Feng's short speech had already made him very clear about what was going on. Moreover, it was already enough to create a warrior with an inner strength of over three thousand people from the special forces of the five big battle zones.

This kind of strength was enough to crush the Special Forces Forces of any country in the world. The only people who could match it were probably the super Special Forces Forces s under the Mi Guo's dark technology.

"It's not that I'm greedy. Elder Xu only thinks this way for the sake of the country." Lin Feng replied with a slight smile.

"Haha, those words still sound comfortable. Let's go, I'll send you off …" Xu Changgeng continued.

"Thank you, Elder Xu!" Lin Feng nodded his head and did not refuse.

Accompanied by Xu Changgeng, they quickly arrived at the airport.

"Xiao Lin, when you have time in the future, come take a look at Sharp Blades."

"As for the position of the Chief Instructor, even if they were to step out three months later, I would still hold back for you."

"In short, in the future, as long as you're still alive, you'll always be a Chief Instructor with sharp blades."

Xu Changgeng stopped and said sincerely and sincerely.

"Elder Xu, I …"

Lin Feng shook his head and wanted to reject, but Xu Changgeng did not give him the chance to speak:

"Xiao Lin, don't worry, this old man will not keep troubling you. You just need to be a nominal Chief Instructor with a sharp blade, and you just need to be busy with what you need to do. When I have time, I just need to come over occasionally to take a look."

In his heart, he had already made a decision. If he did not achieve his goal, he would not rest.

He would always hold the position of the Chief Instructor for Lin Feng, even if it was just a nominal Chief Instructor.

A Chief Instructor of a Martial Arts Grandmaster, this would be … The eternal glory of sharp blades!

"Alright!"

Lin Feng saw Xu Changgeng's determination, and stayed silent for a moment, but in the end, he nodded and agreed.

It was just a name, so it didn't matter if he came over to take a look when he had the time.

"Haha!" "Since you've agreed to it, this matter shall be settled forever!"

"In one day, you will forever be a Chief Instructor with sharp blades."

Xu Changgeng laughed excitedly, the anxiety in his heart, was finally relieved.

"Elder Xu, I'm leaving. When I have time, I will come here to guide them."

"Let's go, the helicopters are already ready to take off. We're safe on our way."

Lin Feng boarded the plane and quickly took off with his helicopter, flying away from the sharp edge base in the cave.
