Urban: His understanding is incredible, and he becomes an immortal starting from practicing martial

Five days later.

Bai Xuan successfully cultivated the Extreme External Refining Method and Muscle Refining Chapter, and exercised the tendon tissue to the extreme.

Absolutely

The extreme here is only the extreme in some aspects, not the extreme in all aspects.

The human body is an incomparably complex structure, and every organ and tissue affects many human body systems and has a variety of functions.

The same is true for the tendon tissue, Bai Xuan can only exercise the length, density, and toughness of the tendon tissue to the extreme, and enhance the protective function of the tendon tissue for the human body and the enhancement function of the locomotor system to the greatest extent.

"Strength, defense, and flexibility..."

After Bai Xuan easily made a few difficult moves, he set his eyes on the boxing force tester hanging on the wall.

"Give it a try and see how much my strength has grown. "

Unhurriedly walked to the boxing force tester, Bai Xuan mobilized many organs and tissues of the human body in an instant, mobilized the strength to the greatest extent, and then punched out.

"Bang !!".

The fist brought up the phantom, and the extremely swift hit the boxing force tester, creating a dull crashing sound.

Four hundred and twelve pounds!

"More than four hundred. "

"Very good, four hundred and twelve catties, an increase of twenty-eight catties from three hundred and eighty-four catties five days ago, and a world record of forty-nine catties. "

"It's already a very exaggerated improvement. "

The stronger the body exercises, the closer it is to the limit, the harder it is to improve.

Even if all the organs and tissues of the human body are exercised to the limit of the human body, the human body is still flesh and blood, and it is impossible to resist bullets.

If you want to have the power to resist bullets, you must break the limits of the human body and master extraordinary power.

It's just....

Not necessarily.

After reining in his thoughts, Bai Xuan's mind also changed.

"Okay, now that the tendon refining chapter has been cultivated, then the next step is to exercise the bones. "

"What kind of changes will happen to the human body after all the skin, flesh, muscles and bones are exercised to the extreme?"

"Strong, tough, even a World Champion can easily defeat me. "

"If I were facing ordinary people, how many people would I be able to fight?".

With some anticipation, Bai Xuan began to cultivate the bone refining chapter.

In the next month, in addition to attending classes and studying, Bai Xuan exercised his bones.

In this way, little by little, the skeleton was exercised to the extreme.

"Bang !!".

A punch comes out.

When the figure of four hundred and fifty-one catties emerged, Bai Xuan also raised the corners of his mouth.

"The strength has increased by another fifty-one catties, which is really an exaggerated number. "

"However, it is also normal, the ability of the skeleton to withstand the strength is the main factor that restricts the strength of the muscles. "

"The stiffness of the skeleton is increased, and it is naturally able to carry more power, which allows the muscles to exert more explosive power. "

"The skin, flesh, muscles and bones are all one, and the strength is surging, which only makes me feel extremely relaxed and light. "

"More importantly, after exercising my muscles and bones to the extreme, I will be able to better grasp and give full play to the effect of Haw Par Thunder Sound. "

Thinking of this, Bai Xuan immediately started to try.

"Buzz!!buzz !!

".

As Bai Xuan exerted his strength, the muscles and bones hummed like a tuning fork, the body trembled, and the power was transmitted to the internal organs.

[You master the sound of Haw Par Thunder, use the principle of sound wave oscillation to exercise the internal organs, feel the changes in the body, combine professional knowledge, further optimize and improve the extreme internal refining method, and can more efficiently use the sound of the tiger and leopard thunder to exercise the internal organs to the extreme.] 】

"Very good, I felt the thunder sound of the tiger and leopard, and sure enough, I can further optimize the extreme internal refining method, but speaking of which, the core of the extreme internal refining method is the thunder sound of the tiger and leopard, so the extreme internal refining method may also be called the thunder sound internal refining method. "

"Lei Yin Internal Refining Method..."

Although it is said that the Tiger and Par Thunder Sound is the core of the Extreme Internal Refining Method.

But the essence of Haw Par Thunder is vibration.

Bai Xuan knew that vibration was a universal phenomenon in the universe.

The overall classification is macroscopic vibrations, such as earthquakes and tsunamis.

and microscopic vibrations, i.e. the thermal motion, Brownian motion of elementary particles.

Some vibrations have a relatively fixed wavelength and frequency, while others do not.

When two objects vibrate at the same frequency, one of them vibrates and the other object vibrates at the same frequency, a phenomenon called resonance.

In addition to breathing, heartbeat, blood circulation, etc., human beings have their natural frequencies, and the brain waves generated by the human brain when it is engaged in thinking activities also resonate.

Similar resonance phenomena are also common in other animals, such as the transmission of brain waves between animals and the exchange of information, which are inseparable from resonance.

"Resonance..."

"Although the current limit internal refining method is very perfect, if I learn about the resonance phenomenon in physics, I may be able to further optimize the extreme internal refining method. "

"Voice, breathing, heartbeat, blood circulation..."

As Bai Xuan fell into contemplation, one inspiration after another kept emerging in Bai Xuan's mind.
