Hard Qigong has always been a relatively special martial art.

It is the only martial art that Shi Tiexin has obtained from other world lines, and it must be the secret inheritance of the so-called "third front". The first layer opens the interface of refining one's own strength, and the second layer is roughly dedicated to defense. But after it was truly perfected, it was discovered that it seemed to be different from the defensive techniques in Shi Tiexin's concept.

It also opens up an interface, or perfects an interface to be precise.

The previous refining interface automatically appeared, and the human figure full of pink smoke was already relatively clear. With the perfect cultivation of the second layer of hard qigong, this light and shadow human form suddenly gave birth to some changes.

I saw the outside of the limbs, the back of the waist and the back of the neck, the hands and forearms, etc., all the places where the hard qi exercises went, all flew out of a projection, and formed a new figure next to the pink figure.

This is the second image of the refining interface.

The figures resemble pieces of armor made up of pieces of armor, worn on a completely transparent stroke figure.

Directly above this brand-new picture is a horizontal line written on it, which is exactly the "tough skin" written before.

On the right side of the humanoid hangs a progress bar, called [Muscle Armor], and the progress has reached []

"Muscular?" Shi Tiexin looked at this picture and had some guesses in his heart. The phantom of the armor in the humanoid form does not cover the entire body, and the thickness is only related to the superficial fascia of the humanoid form, not the muscles. So this set of "muscular armor" is not perfect, and there are still many weaknesses.

"If you practice other body protection martial arts, the integrity of this set of muscular armor should continue to improve."

How useful will the muscular armor be when it is fully repaired? I don't know, go to the dog gang another day and brush it again to try the effect.

"Wait a minute, what did I find?" Shi Tiexin suddenly saw something that surprised him: "I saw a body refining button!" ”

That's right, the lower abdomen of the light and shadow humanoid in the picture of the muscular armor also has the virtual image of a false pill. The "second layer of hard qigong" turned into a badge, slammed on the fake pill, and then extended an illusory line connected with the phantom of the "strong and tough membrane".

Shi Tiexin tried to transform his essence

With a crackling sound, the essence in the fake pill fell rapidly like a flood, faster than when cultivating one's own strength. At the same time, the big tendons bulged more hideously, extending in all directions like veins.

"I'll go! It feels so exciting! ”

The sudden sharp pain made Shi Tiexin's face suddenly red, the blood vessels in his forehead jumped suddenly, and both eyes were full of bloodshots.

But at the same time, the effect is also very powerful.

I saw that wisps of smoke were also released from the lower abdominal badge of the second picture.

But the smoke was no longer pink, but red, a blood-red color. The texture of the red smoke was much stronger than the pink smoke, and they drifted into the position of the hard qi exercise. Under Shi Tiexin's control, most of the red mist was poured into his right hand.

"Shhh Shi Tie's distressed straight gums only felt as if magma flowed into his arm along the blood vessels, and finally flowed to the surface of the fascia. For a while, the entire skin membrane of the right hand seemed to be about to burn, and the pain made people break out in a cold sweat.

Shi Tiexin endured the pain, worked hard to induce the second layer of hard qigong, and repeatedly tempered the skin membrane of his arm. After a while, the pain subsided, and the red mist was fixed into a red haze.

Although there are not many red haze converted this time, it does not account for a large proportion of the light and shadow virtual images. But Shi Tiexin looked at his right hand in a daze, he felt that his right hand was more textured than before. This red haze has not changed the strength of the right hand, but the strength of the fascia surface of the hand has been really improved.

clenched his fists and slapped himself twice, Shi Tiexin was a little dazed.

"It's already tougher than the big hand who practiced iron palms...... And this is a defensive state permanent?! ”

The defense buff of the second layer of Hard Qigong originally required a puff of strength to be used, so it was impossible to use it all the time to master the timing.

For example, in the dream, the instructor tears the bark by hand, and first needs the first layer of hard qigong to practice the body, and then the second layer of qi fills the skin table, and when it is ready, it can be torn off with one claw. In one breath, the high-defense state is dissipated. So it's impossible for him to scratch the bark with both hands like a kitten.

But now, Shi Tiexin obviously didn't have any special strength, and the defense of his hands had already been improved. Of course, the lifting effect is not as strong as when it is inflated, but now I just tried to practice it. If you fill the entire hand with red smoke...... Am I going to be able to scratch the tree in a row?

"Yes, yes, hard qigong can really surprise me. Moreover, I estimate that this muscular armor may be part of the next refining body, and the red haze is likely to be the key to further refining. It's just that there is no body refining method now, and it is a pity that the red smoke and haze cannot be refined into the body. ”

Shi Tiexin was happy while feeling sorry, and then continued to work hard to pour the red mist into the tough membrane.

After more than half a month, the tough skin that can be practiced now has been completely cultivated, and the defense has been greatly improved. This tough membrane has no abnormalities on the surface, and no one knows how strong the defense will be if they don't move, and the difficulty of keeping the secret is not high.

In this way, stable development. Until one day, the badge with the word "win" faded away. Only then did Shi Tiexin suddenly realize that he had been in the state of creating a genius for two months.

In the past two months, he has developed with his head covered, and he has made rapid progress and outstanding results, completely cultivating the second layer of cloud legs and hard qigong, and cultivating the third layer to profoundness.

It doesn't seem like there are many doors, but the martial arts of the second and third layers are already more difficult than those of the first layer. Without relying on anyone to bring points and purely self-study, this is already the same speed as drag racing.

As soon as the "win" badge disappeared, he was a little unaccustomed to it.

At the same time, Shi Tiexin suddenly discovered that he had no martial arts to practice.

Several times all the martial arts in his hands, the only thing that remains is not perfect is the third layer of hard qigong. The third layer is pure defense skills, which can allow him to gather energy faster, exert force, extend the duration of high defense status, and increase flexibility when defending, but these are of little meaning to him who has developed a tough skin.

Now he could only look forward to whether the third layer of perfection would bring any surprising attributes, so he pushed forward all the way without hurry.

But how long can a third layer be practiced by him? In another half a month at most, I will be able to push it to the limit, and what will I practice by myself when the time comes?

How could the landlord's family have no surplus grain? There is no martial arts to practice, I can't cough!

"Are you going to exchange the bullet legs, or are you going to the secret market to have a look?" Shi Tiexin was looking for it, when he saw a familiar phone call suddenly called.

"Uncle and brother, the smoking teacher is here, let's go to school together tomorrow!"
