His current qi and blood have not grown for a long time.

Almost stopped.

Just the level of a second-rate expert.

They are far from reaching the second-rate peak.

So, Shi used the Gang Power to slowly penetrate into the qi and blood in his body.

"Buzz".

Sure enough, Shi Yun's qi and blood seemed to be stimulated. Gu Zuo

He actually started to "rush".

Moreover, the Gangjin can penetrate into the muscles.

There seemed to be a slight change in the muscles.

After only a while of stimulation, Shi Yun found that he consumed a lot of energy.

But it really works for qi and blood.

The speed is almost visible to the naked eye, and the qi and blood have increased a little.

This is hope for Shi Yun!

"Wait, the Gangjin can penetrate into muscles, qi and blood, so what about the bones?"

Shi Yun knew vaguely.

After the martial arts, he actually tempers his muscles and bones.

It's mainly bones.

Because only the internal strength of the martial artist can penetrate into the bones and temper the bones.

Shi Yun tried it.

He mobilized the energy and penetrated into the muscles, qi and blood little by little, and finally penetrated towards the deepest bones.

"laugh".

Shi Yun was shocked.

He felt like he was electrocuted deep in his bones, and his heart hurt.

Then, his strength was almost exhausted.

Shi Yun started to think.

Gangjin can penetrate into bones.

But the efficiency is too low.

The effect of Gangjin penetration into the bones is not very good.

After all, Gangjin also needs to penetrate into the muscles, qi and blood first, which is equivalent to crossing two layers of obstacles in a row before finally reaching the bones.

Qi, blood and muscles can consume more than half of the penetrating energy.

"So, it is still necessary for internal martial artists to temper their bones."

"After all, internal strength is born from qi and blood, and can penetrate directly into the depths of the bones and directly temper the bones!"

Shi Yun murmured in a low voice.

He vaguely knew why only internal martial arts are "authentic" martial arts.

Because only internal martial arts can produce internal strength.

Only after becoming a martial artist can you continue to temper your bones and go further.

Even if a Gangjin martial artist can produce Gangjin, it will take twice or three times more powerful than an internal boxing martial artist.

If this continues, it will be almost impossible for the Gangjin Martial Arts to go further.

Therefore, basically, once an ancient martial artist becomes a Gangjin martial artist, there is only one choice.

That is to practice internal martial arts again.

It is only a matter of time before you have the stimulation of Gangjin, practice internal martial arts and make the qi and blood produce internal strength.

It's much simpler.

"call....."

Shi Yun breathed a sigh of relief.

Finally, he became a military master of Gangjin, and a huge rock in his heart was completely put down.

“My feet have hope to recover.”

Shi Yun knew very well that his legs were broken.

Only by using force to temper the bones, his right leg will be able to slowly heal and even heal!

Of course, the premise is that you have to practice internal strength first.

Otherwise, relying so much power to temper the bones is too unprofitable and inefficient.

But the problem now is that Shi Yun doesn’t know how to improve Gangjin?

Do you have to rely on skin grinding?

That's simply impossible.

In the past, those ancient martial artists had no effect after they became Gangjin.

It seems that we have to find the martial arts above Gangjin.

Or, continue to temper qi and blood.

Let the qi and blood produce internal energy.

"The total amount of Gangjin is too small."

"And you also have to temper your qi and blood, and the recovery speed of Gangjin is very slow."

"If this continues, I'm afraid I can't even use Gangjin for a long time."

"We must find a way to increase the total amount of Gangjin in a short period of time."

Shi Yun frowned and fell into deep thought.

He took a closer look at Gangjin again.

"Wait, my Gangjin seems to be just the first layer of copper skin."

"My current first layer of copper skin is the copper skin produced by the power removal exercise."

"For other warriors, even ancient warriors, there is only one layer of copper skin, and only one kind of gang power can be produced."

"But, I'm different. I have four layers of copper skin in total."

"Can every layer of copper skin give birth to a kind of magnitude?"

"Then I can give birth to four kinds of Gangjin?"

"Whether the last four kinds of gang force are integrated or not, my total amount of gang force can be increased four times in a short period of time!"

Shi Yun's eyes lit up.

This seems to be a good idea.

Moreover, it sounds quite reasonable.

Shi Yun even felt that if his other three layers of copper skin were to produce Gangjin, he would no longer need to use red sand to grind the skin.

Now Shi Yun has Gang Power.

Gangjin can easily cover the copper skin, but it can also easily tear the copper skin.

The essence of Gangjin is still the energy.

It is also easy to tear the copper skin.

Therefore, using Gangjin to remove skin effect will definitely be very good.

This may also be Shi Yun's innovation.

Use Gangjin to remove skin grinding.

I am afraid that from ancient times to the present, no warrior has used this method.

After all, the warrior who gave birth to Gangjin did not need to be polished.

There is no second warrior, who can have two layers of copper skin.

“Try it.”

Shi Yun did it when he thought of it.

He mobilized the Gang power and began to penetrate into the second layer of copper skin, which is the copper skin of Zhenjigong.
