"Young Master, Master Tong is back, he is now in the martial arts training ground, and he also pulled back a big cage covered with a black cloth, which seems to contain some fierce beasts. A servant rushed to report.

Ye An replied happily: "Got it, you go down." Then he rushed to the martial arts training ground.

At this time, there was a large cage more than one or two meters high and three meters long, covered with black cloth on the martial arts training ground, and there was a sound of breathing like thunder from the inside, and there was a faint fishy smell.

Master Tong was standing on the edge of the big cage, his right arm was wrapped in gauze, there was a faint blood stain on it, and his expression was sluggish, and it seemed that he had made a lot of effort for his own affairs.

Ye An was moved, hurriedly stepped forward, and said with concern: "Master Tong, how could you be injured, does it matter?"

Tong Chengyi shook his head and said indifferently: "Thank you young master for your concern, it doesn't matter if I have a small injury, just go back and recuperate for a few days." ”

After speaking, he pulled off the black cloth on the side, revealing the scene inside.

At first glance, Ye An was startled.

It was a tiger larger than an adult bull, curled up like a hill, with an aura of fright.

"Young master, this is a fierce beast-level tiger, I took people into the mountains for seven days, and went around more than a dozen mountains with this beast, and finally this beast couldn't help but be hungry, so he was fascinated by drugs. Tong Chengyi said proudly.

There is a demon race in this world, and the demon race generally refers to two kinds, one is a high-ranking race, which has wisdom and strength since birth, has its own inheritance exercises, and can absorb the aura of heaven and earth, which is like a genius with spiritual roots in human beings;

Beasts can become fierce beasts when they are constantly trained and fought in nature, and their physical strength reaches the peak of their race.

The beasts are fierce and bloodthirsty, and some of them are gifted enough to break through the limits of their own race and become fierce beasts by observing all things in nature and comprehending a trace of superficial cultivation and training.

Fierce beasts are the existence of natural enemies, they already have a trace of wisdom, can imitate and learn, compared to fierce beasts, they are more cunning, can restrain their bloodthirsty nature.

The strength of the fierce beast is powerful, comparable to the innate martial artist of the human race.

The fierce beast continued to exercise and cultivate, and one day felt the existence of the aura of heaven and earth, so that it began to absorb the essence of heaven and earth, sun and moon in ignorance, and under the nourishment of the essence of heaven and earth, it could become a demon beast.

Demon beasts have higher intelligence, and their existence is equivalent to that of human cultivators, capable of wielding demonic energy and sending out all kinds of powerful attacks.

It is said that the original martial arts of human beings were created by imitating fierce beasts and fierce beasts, and now looking at Master Tong's arrangement, it is estimated that this legend is inseparable.

Seeing this fierce beast tiger, Ye An was also taken aback.

This fierce beast is comparable to the fierce existence of the innate martial artist, and the jungle tyrant like the tiger and lion has become a fierce beast, and the strength is even stronger, and the innate martial artist may not be their opponent.

Looking at the size of this tiger, it is estimated that an ordinary person can be torn apart with one claw.

Seeing that Ye An was startled by the fierce beast tiger, Tong Chengyi was also proud in his heart.

"Young Master, what is Haw Par Lei Yin?"

Tong Chengyi didn't wait for Ye An to answer, and then explained: "It's hard to say clearly, you can only know if you feel it yourself." ”

"Not long after this beast took the drug, the young master pressed his hand on its back, and felt it quietly, I believe that it will not be a few days before I can comprehend the true meaning of the thunder sound of the tiger and leopard. Tong Chengyi said confidently.

Ye An looked at the tiger lying in the iron cage, and always felt hairy in his heart, but in order to feel the thunder of the tiger and leopard, Ye An still listened to Master Tong's words and pressed his palm on the tiger's back.

Close your eyes and feel still.

A strong heartbeat, one after the other, and a faint muffled thunder that lasted for a long time.

This muffled thunder was very special, Ye An seemed to have comprehended something, and it was as if he had not comprehended anything.

After thinking about it, Ye An directly used the analysis function of the biochip to analyze what was going on with the muffled thunder in the body of the tiger in front of him.

The 3D three-dimensional composition of the tiger was directly generated in Ye An's retina, and then the muscles and internal organs were filled one by one, and soon one data after another was quickly swiped by.

The flow of blood, the rate of breathing, the direction of air flow in the body, and so on are all analyzed.

In less than two seconds, the fierce beast tiger was thoroughly analyzed by the powerful biochip.

And Ye An also got the answer to the muffled thunder from the biochip, and also knew the real mystery of the so-called "tiger and leopard thunder".

It turns out that when the tiger breathes, the gas passes through the cavity in the body to produce a certain frequency of oscillation, which produces a special frequency of sound waves, which shrinks the gap between the muscles and bones in the tiger's body, that is to say, the bones of the same volume, after the baptism of sound waves, the latter's muscles and bones are denser than the former.

And this kind of vibration will emit a sound like thunder in the body, which is the origin of the thunder sound of the tiger and leopard.

After reading the analysis of the biochip, Ye An also understood that the mystery is not in the so-called "tiger and leopard thunder sound", but in the special frequency of sound waves, as long as the frequency of the oscillation is found and the body emits sound waves to radiate the muscles and bones in the body, the body will naturally be enhanced.

Ye An suddenly realized, thinking that although other martial artists did not know the nature of the shock, nor did they know the so-called sound waves, they understood the benefits of this kind of shock, so when cultivating, let the body emit shocks, and constantly adjust, so that the frequency of the shocks continued to approach the "Tiger and Leopard Thunder Sound".

In the end, you can get the benefits of washing the body and strengthening the muscles and bones.

Thinking of this, Ye An also understood that the role of this fierce beast tiger on himself had been completed.

"Master Tong, I have already understood, thank you for your hard work. Ye An smiled and said gratefully: "Wait until you go to Yi Bao Pavilion to find Shang Lao to receive three bottles of essence qi pills, go back and rest for a few days, I am also ready to let you teach me a little more martial arts!"

Tong Chengyi smiled with satisfaction, three bottles of essence pills, although he didn't use them very well, but it was still very good to use them to improve his son's strength.

This essence pill can't be bought with money, you have to have a spirit stone!

He, a martial artist of the Acquired Realm, may not have been able to exchange for two spirit stones for a year, these three bottles of essence pills are worth 9 spirit stones, and he came back after nearly five years of exchange at once, this trip can be described as super valuable.

After Tong Chengyi left, Ye An returned to the study.

He now also knows how to complete the baptism of "Tiger and Leopard Thunder Sound", mainly through breathing, air flow through the body, using force to control the cavities in the body, so that the body is like a flute, inducing vibrations, emitting sound waves, and refining muscles and bones.

Originally, he didn't know the internal cause, so Ye An cultivated according to this orthodox martial artist way, but now that he knew the cause, he naturally wanted to think of a more efficient method.

First of all, this kind of "tiger and leopard thunder sound" cultivation method of orthodox martial artists was created by imitating the cultivation of tigers, leopards and other fierce beasts, that is to say, the oscillation frequency generated by this "tiger and leopard thunder sound" is not the most suitable for one's own body.

This method of "Haw Par Thunder Sound" refining can not achieve the maximum effect.

In addition, due to control reasons, the frequency of oscillation cannot always be maintained at the same appropriate frequency, which also makes the training of "Haw Par Thunder" take a long time.

Now that he has found the secret of refining his body, Ye Anzi needs to use biochips and auxiliary nanoparticles to complete this process quickly, and he must complete it quickly and well.
