The muscles and bones roared together, the air waves surged wildly, and this was the first time that Song Xing used his tyrannical physical skills to practice boxing skills after achieving the level of blood exchange.

The air waves rolled like thunder, drowning out the sound of the sea breeze and ringing above the deck.

Xiuyu Valley entered the realm of blood exchange, and after three months of hard training, Song Xing completely stabilized the realm of blood exchange.

Blood transfusion, as the name suggests, is to replace all the blood in the body with blood that can hold more Danjin. When the new blood flows throughout the body, it will perform a second bone cutting and marrow cleaning to further strengthen the muscles and bones, reaching the point of a cycle.

.

As Song Xing practiced the Twelve Movements of Yijin, Danjin transported Qi, blood and true Qi, and the true Qi blended into the Qi and blood, accelerating the process of strengthening the physical body, making Song Xing's body even more powerful, with every punch and kick, there was the sound of wind and thunder.

.

Lu Xiaofeng didn't know when she appeared on the other side of the mast, and she was stunned as she watched Song Xing practice his boxing.

There are many people in the world who specialize in physical and horizontal kung fu, and some of his friends also practice external kung fu. Originally, he was gambling down there, but when he saw Song Xing practicing boxing there, he didn't think much of it.

He had seen many martial arts idiots like Song Xing. When Ximen Chuixue was practicing swordplay, even if there were a hundred beauties stripping naked and dancing in front of him, he could still practice his swordsmanship calmly.

But when the noise of Song Xing practicing boxing became louder and louder, he couldn't sit still anymore.

With his eyesight, after watching carefully for a while, he found that Song Xing was really just practicing boxing. There was no real energy flowing between his fists and feet. He was solely relying on his own body to make such a big noise.

The heaven and earth stirred, and the sound was like thunder.

This sentence talks about the movement caused by the body's instinctive reaction in every move when the internal martial arts is practiced to an extremely deep level.

The essence of martial arts lies in physical fitness, which is a system of exercises that revolves around the cultivation of Dantian and spine.

The highest level in the internal elixir-holding technique is called Hubao Leiyin. After practicing martial arts to a high level, the opening and closing of the golden elixir is like a broken bean. While the muscles tremble at a high frequency, the muscles and bones are affected to vibrate together. To the ears of others, it sounds like

I heard the roar of the waves and the rumble of thunder at the beach.

The earliest ancient martial arts were boxing techniques practiced by sages by imitating animals. Among animals, tigers and leopards are the first, and they are at the top of the food chain.

The rhythm of the boxer's muscles and bones shaking and rubbing is created by simulating every movement of the tiger and leopard's spine when walking, hence the name tiger and leopard thunder.

In the Kung Fu system that Lu Xiaofeng practiced, there was only the theory of internal energy and true energy, and he had never been exposed to the concept of Qi, so when he saw Song Xing practicing boxing, he was shocked.

He had never thought that someone would cultivate his physique to such an extent that he could walk, sit, and sleep in the small space of the mast, and simply pump his fist, accompanied by strong winds and rolling thunder.

With his ears, he could even hear the sound of running water coming from Song Xing's body.

That is the sound produced by the blood surging in the blood vessels during Song Xing's movement.

For a moment, Lu Xiaofeng even suspected that Song Xing was a big demon walking in the world wearing human skin.

As for the sailors and ship boss who were shocked by Song Xing's boxing practice, they stood below, dumbfounded, looking at Song Xing with eyes like gods. The timid ones even knelt on the deck and murmured in worship.

The honest monk stood at the door of the cabin, looking at Song Xing above with a somewhat ugly face, then lowered his head and chanted, not knowing what he was thinking.

After completing the twelve posture drills, Song Xing slowly withdrew his fists, and the muscles and bones in his body vibrated again, startling a group of seagulls flying overhead.

A falling white feather slowly fell from the sky and was about to land on Song Xing's shoulder, but suddenly it was shattered by an invisible force as if struck by lightning.

"Body-protecting Qi!"

When Lu Xiaofeng saw this scene, she couldn't help blurting out.

According to rumors, after practicing Kung Fu to the innate state, the inner energy of the body is overflowing, and a layer of true energy will be formed outside the body, blocking attacks from all angles in all directions without blind spots.

What Lu Xiaofeng saw at this moment was undoubtedly very similar to the rumored protective energy.

Song Xing burst out with strength, shook the broken feathers on his shoulders away, shook his head and said: "It's not the body-protecting Qi, it's just a little technique to exert force."

The joy in his tone could not be concealed at all.

On top of Dan Jin, there is even more Gang Jin.

After the blood exchange realm is stabilized, Dan Jin absorbs more and more innate Qi and will evolve into a more powerful force, Gang Jin.

Gang Jin is a higher level evolution of Dan Jin. Externally, it can achieve the effect of volleying through the body and hitting externally. Internally, it can form Gangjin airflow on the body surface to rebound external attacks and injuries.

The cultivation systems of the two worlds are different. Even if he told him, Lu Xiaofeng would not understand, but this did not prevent his fear of Song Xing from rising again.

This man named Song Xing suddenly appeared as a mysterious master in the world. First he impressed Sikong Zhaixing, then defeated the honest monk with one move, and now he showed off his inhumanly powerful foreign martial arts skills.

Lu Xiaofeng asked herself that she had met countless people, but she still couldn't figure him out. On the contrary, every time she communicated with him, she always felt that this person could see through her to the extreme.

The boxing skills practiced before by Guan Songxing have faint shadows of Shaolin moves, but I have never heard that Shaolin has such a powerful external training that can achieve the effect of infuriating the body.

Song Xing lowered his head and glanced at the honest monk's position, and sat directly on it without getting down from the mast.

Lu Xiaofeng took out two small bottles of wine from her arms, threw one to Song Xing, and walked to sit next to him.

Song Xing reached out to take the wine bottle, opened it and took a sip, feeling a spiciness erupt in his mouth.

Lu Xiaofeng said: "The sea is humid and cold, and the burning knife from Guandong is the best way to keep away the cold. It is the favorite of these sailors."

Then he looked at Song Xing, shook his head and said, "But with your physique, I guess you don't need it."

Song Xing glanced at him and asked, "What do you want to say?"

Lu Xiaofeng asked curiously: "Monk Honest is not weak in martial arts, but he can't even block one of your moves. What is your identity? What sect do you come from?"

"You don't know even if I tell you." Song Xing continued to take a sip of wine and said.

Lu Xiaofeng obeyed: "Okay, if you don't want to say it, I won't ask, but I'm still curious. Before leaving, you asked Sikong Zhaixing to help you find something. With his character, why would he agree to it?"

When the honest monk agreed to take Song Xing to find the little old man, Sikong Zhaixing said that he was not interested in these things. Since he helped Song Xing find Lu Xiaoji, the rest of the things had nothing to do with him.

However, Song Xing reminded him and asked him to find a treasure for him. Although he was reluctant, Sikong Zhaixing still agreed.

When Lu Xiaofeng asked, Song Xing said, "He has something in my hands."

Lu Xiaofeng was surprised: "How can Sikong Zhaixing be in your hands? Isn't this the first time you've met?"

"Yeah." Song Xing nodded, but did not tell Lu Xiaofeng what the reason was.

Although Lu Xiaofeng was very interested in the reason why Sikong Zhaixing was involved, but Song Xing didn't mention it, he just ignored it.

"A treasure that the King of Thieves can look for is definitely a priceless treasure."

Song Xing still didn't answer. What he asked Sikong Zhaixing to find was the white jade cup, one of the three divine objects that Jade Seal asked him to find.

"Records of Ten Continents": During the reign of King Mu of the Zhou Dynasty, Xirong offered a jade cup, which illuminated a room. He placed the cup in the atrium and the water would be filled tomorrow.

The white jade cup of King Mu of Zhou Dynasty, the thirteen-fold arm box of the Xiahou of Hailing, and the dragon and beast wall paintings of Qianxiao Lieyi, are all the sacred objects that the jade seal designated Song Xing to look for.

After Song Xing woke up in the Palace of Hell, he arranged for people to search for the whereabouts of these antiquities. Perhaps because of their age, or perhaps because the Palace of Hell was not powerful enough, nothing was found.

This is related to whether he can leave this world in the future, so Song Xing has always been very concerned about it.

Until he met Sikong Zhaixing, he had an idea and asked Sikong Zhaixing to find the whereabouts of the white jade cup for him.

Unlike the thirteen-fold arm box and the dragon and beast wall paintings, Song Xing speculated that the white jade cup of King Mu of Zhou was likely to be passed down to the world as an antique.

If you want to know the whereabouts of these treasures, who better than Sikong Zhaixing, the king of king thieves.

It just so happened that Sikong Zhaixing seemed to have noticed some clues and decisively withdrew from the Honest Monk incident, so Song Xing asked Sikong Zhaixing to handle the matter.

Lu Xiaofeng looked at the endless sea water around her and asked, "Who is the little old man?"

Song Xing said: "He is a man with extremely high martial arts skills."

"How high?"

"As high as three or four stories."

Lu Xiaofeng nodded and said with a smile: "Then you have to travel across mountains and rivers and across oceans to find this person with extremely high martial arts skills. You can't be looking for him to compete in martial arts, right?"

If Ximen Chuixue went all the way to find another swordsman to compete with, Lu Xiaofeng thought it was still possible.

But for Song Xing, he always felt that everything he did was not without purpose. It was precisely because of this feeling that he followed Song Xing to the sea, just to see what he was going to do.

The wine bottle in his hand only had a capacity of two or three taels, and it reached the bottom in just a few gulps. Song Xing drank the rest of the wine in one gulp, turned to look at Lu Xiaofeng, and uttered two words: "Kill."
