In an inconspicuous courtyard somewhere in the Boxer camp in Jinmen, several fierce militia members guarded the courtyard to the water, and did not allow any outsiders or even high-level Boxers to approach.

This is the forbidden area of the Boxer camp, and it is also the most mysterious place.

WhewW......

At this time, in the center of the spacious barracks, I saw Lei Hu's feet separated from each other, standing a half-step mixed yuan pile, his knees slightly forwarded, and his breathing between his mouth and nose was heavy one after another, sounding as if a big cat was hiding in his throat, although the voice was not loud, it was exceptionally clear and powerful.

Exercising the fascia and ligaments of all parts of the body through the vibration of the breath is originally a unique internal practice method in Neijiaquan.

Start with the basics of breathing. Regulate the body and mind, supplemented by the strength of the horse step pile, once this kind of kung fu is practiced to the most profound point, the muscles and bones of the whole body will produce a qualitative change.

At this time, the kung fu has been formed on the outside and manifested on the inside.

To put it bluntly, the breath must be immersed in the internal organs, and to achieve this step of kung fu, in the inner boxing is the thunder sound training, that is, the "tiger and leopard thunder sound" in the inner boxing!

At the same time, 'Tiger and Par Thunder Sound' is also one of the most effective methods of practicing the marrow, and it is a realm that many grandmaster-level masters are eager to enter.

This kind of realm is not something that can be comprehended when you reach the level of transformation.

Not to mention, simply imitating the tiger and leopard rubbing the bone joints and shaking the viscera is not something that ordinary martial artists can do, or can bear.

Felines, especially tigers and leopards, usually have a sound that keeps ringing, that is, the sound produced when the muscles and bones burst out, so the bones of feline predators in the animal kingdom are particularly powerful, and tiger bones and leopard bones are also the most nourishing things in traditional Chinese medicine.

And the so-called thunder sound is not a loud thunderclap when thunder, but a faint thunder sound above the clouds before the rain, which seems to be there or not, and the sound is small and deep.

Those who practice inner boxing learn from nature and learn the pronunciation of tigers and leopards. In order to use sound to vibrate the internal organs, and to exercise the bone marrow, which is the most difficult to exercise, is the foundation of transforming the body. Kung Fu is a success, in the words of the novel. That is to completely wash the marrow and be reborn.

In reality, such a person only has a hematopoietic function that exceeds ordinary people by dozens of times, so that the physical strength can be maintained at an unimaginable peak state for a long time. Not human-like.

At this time, after more than a year of intensive training, Lei Hu's muscles and bones have reached a certain limit that the physical strength can withstand at this time.

In modern terms, the density of bones increases, both strength and hardness are much stronger than ordinary people, and with a tougher fascia, it can exert amazing strength when exercising, and at the same time, the defense is also one top and one strong.

The qi and blood in the body are also extremely rich, and once you exert your full strength, there is a kind of blood veins bursting with blood vessels, as if the qi and blood are filled to the limit that the body can bear.

Next, the qualitative change is caused by quantitative change, and the hematopoietic function of the bone marrow must be upgraded in order to provide higher quality blood, which leads to the sublimation of the entire physical fitness.

His strength has reached this point, and there is no possibility of retreating, either it is the result of overflowing water, or he will go further through training, and there is no third way to choose.

Lei Hu naturally chose to move forward bravely, and after the completion of the bone training, he must enter the stage of training the marrow, otherwise it is difficult to say what the situation will be in the future.

The thunder sound of the tiger and leopard is a very special state, by imitating the behavior of the tiger and leopard, as well as the movement of the muscles and bones, to achieve the purpose of shaking the viscera and tempering the bone marrow, which is a very good means of training the marrow.

At this time, Lei Hu was about to enter this special realm, with a faint thunderous sound between exhaling and inhaling, and the frequency of breathing became longer and longer.

WhewW......

The sound of thunder grew louder and louder, and later it was even more deafening.

The viscera vibrated and made a trembling sound, and as the sound became louder and louder, it turned into a leopard's roar, which was deafening and moving, as if there was really a cheetah hiding in the dark and ready to attack.

At the same time, the qi and blood in the body vibrated and the viscera vibrate, the joint fascia around the body trembled again and again, the vertebrae followed by a slight tremor, and the bone fascia rubbed into a small sound, but the sound became louder and louder as time went by, and finally it became an amazing tiger roar.

Haw Par Thunder!

The spine itched, and a hot current rushed straight up from the tail vertebrae, spreading rapidly along the limbs and hundreds of remains, and the qi and blood in the body boiled like a closed furnace.

At this moment, he felt unprecedented comfort, only to feel that his body had inexhaustible strength, as well as terrifying power, and he had the urge to look up to the sky and let out a long roar.

I am so unhappy in my heart, after such a long time of accumulation and exploration, today I finally reached the level of tiger and leopard thunder sound, and officially entered the stage of practicing the marrow.

When the bone marrow is exercised and the hematopoietic function is qualitatively improved, the qi and blood energy in the body will also be greatly improved, so as to achieve the purpose of comprehensive improvement.

It took another hour to stabilize the realm of the tiger and leopard thunder sound, and by the time the work was finished, the whole body was completely soaked with sweat, and there was a little strange smell of mold, and he could even rub off a layer of gray and white grease when he reached out and rubbed it vigorously.

Obviously, this is the dirt in the body squeezed out by the body after the cultivation of the tiger and leopard thunder sound, no wonder the smell is so unpleasant, but at the same time, the body feels extremely relaxed.

……

"Master Tiger, the silly second is visiting!"

After washing his body a few times, he felt that the dirt squeezed out of his body had been thoroughly cleaned, Lei Hu had just changed his clothes, and the elite of the militia guarding outside reported loudly.

"Let him in!"

Lei Hu greeted, and soon the Divine Whip Silly Er walked in with the guard, and when he saw Lei Hu, he smiled honestly and said directly: "Master Tiger, senior brother asked me to pass on a message to you, the prince over there in the capital agreed to our conditions, but we want to obey the command of the imperial court and immediately send some people into the capital!" ”

"Oh, what's going on, to be in such a hurry?"

Lei Hu raised his eyelids and asked curiously, "How many muskets did the capital promise to provide to the Boxers, as well as how much ammunition and grain and grass supplies?" ”

Because he felt that it was possible to break through the realm, he had been nesting in the camp for the past few months and had not gone anywhere, and had greeted the senior brother of Yihequan, so he didn't bother him if it wasn't particularly important, so he didn't know much about the outside world, and he didn't know what was going on in the capital, and he had such a big concession?

"I don't know!"

Silly Er looked dazed, and said, "I just heard that the Queen Mother turned her face with foreigners......"
