Pulp wash and exchange transfusion.

This is a level that can only be attained by cultivating the superior bone forging skills to perfection.

Under normal circumstances, if the bone forging martial artist starts to exchange blood, if the personal qualification is ordinary, then even if he takes tonic medicine every day, it will take three or five years to complete the blood exchange, and if it is fast, it will take one or two years.

In addition, the older the age, the lower the success rate of marrow exchange transfusion.

Basically, if you are over 30 years old, the chance of success is very small.

Chen Xuan is only seventeen years old, his own qualifications have reached the top level, and he also has blood exchange beads, which can greatly shorten the blood exchange time, and it is even possible to complete the blood exchange within a month.

Immediately, Chen Xuan swallowed the blood exchange beads.

Two quarters of an hour later, the beads dissolved in the stomach and turned into a stream of cold air.

Chen Xuan immediately mobilized his strength, and used the Donkey Kong fist's method of refining bones to infiltrate the cold air flow transformed by the blood exchange beads into the bones, and entered the bone marrow area to fuse with the bone marrow.

As the power of the blood exchange beads was integrated into the bone marrow, the speed at which the bone marrow created new blood was immediately increased by more than ten times, and the old blood was discharged through the pores.

In the process of exchanging blood, Chen Xuan's actions were not affected.

Just avoid fighting with people.

Staying in the medical camp, Chen Xuan basically would not fight with others.

Time passed.

The bone marrow creates more and more new blood, Chen Xuan feels the qi and blood in his body, the qi and blood are surging and boiling in the body, and the strength of the blood is constantly increasing.

Qi and blood are full, the strength of blood is increasing, and the strength contained in it is also becoming stronger.

Whoa—

Chen Xuan used his strength and could hear the sound of waves coming from his body.

"The blood is like mercury, the blood is surging, I have already completed the exchange of blood."

Chen Xuan felt the power in his body, and between his punches and kicks, there were thousands of catties of power.

From the beginning of the blood exchange to the end of the blood exchange, it only took fifteen days, and after the blood exchange was completed, the power of qi and blood was more than ten times stronger than that of ordinary people, and the cultivation of the Dirty Realm could begin.

Refining the viscera is to strengthen the viscera and make the viscera tougher.

The flesh, muscles, and bones of a warrior are tempered and strengthened, and they can withstand stronger power impacts, but if the internal organs are too fragile, the fighting power rushes into the body, and it is easy to injure the internal organs and die from internal injuries.

Once you have an internal injury, it can be much more serious than an external injury.

Some internal injuries may accompany the warrior for a lifetime.

Refining organs, in addition to making the organs more tenacious and bearing stronger impacts, can also strengthen the digestibility of organs and organs, anti-toxicity, etc., even if some bones are swallowed directly without chewing, they can be digested, and ordinary poisons do not play a big role in refining visceral martial artists, and they can be quickly excreted through metabolism.

Even if you have some injuries, as long as they are not serious, they can heal on their own.

At the same time, the lung capacity of a martial artist who has reached the realm of refining dirt is also amazing, and practicing sonic martial arts can directly break a person's diaphragm, or even directly shock a person to death, and take a deep breath to hold his breath underwater for more than two quarters of an hour.

Even if you don't eat for ten days and half a month, you won't starve to death.

In short, those who have reached the realm of refining the viscera have all kinds of miraculous powers, their vitality is much more tenacious than that of ordinary people, and their visceral organs have been strengthened and glowing with new vitality, and their lifespan can be increased by more than ten years.

But it is not easy to step into the refining of dirt.

Refining dirt is completely different from refining skin, forging bones.

Refining skin, forging bones can withstand the impact of qi and blood strength, and can even use horizontal refining to hit the flesh to speed up the progress of cultivation, but the viscera cannot.

The viscera are much more fragile than the skin, flesh and bones, and if the strength is slightly impacted, it may be injured.

Refining the dirt is the same as washing the marrow, and it is the same as washing the marrow, and it is the general kung fu of water milling.

Therefore, refining organs can also be called nourishing organs.

The four realms of forging the body, among which the cultivation realm, the refining skin realm and the forging bone realm are mainly in movement.

Whether it is the cultivation of the martial arts Yuanyang Boxing, or the refining of the skin martial arts of the Mighty Elephant Boxing, the Iron Cloth Shirt, and the Bone Forging Amber Gong Donkey Kong Boxing, the most important word for the Lord is 'move', so that the body moves.

However, refining the dirty realm cannot withstand the violent impact of strength and blood, and can only rely on warmth.

Chen Xuan took out a copy of the dirty martial arts he had purchased.

This dirty martial art is called "Turtle Breath Dirty Skill".

The first three realms of the four realms of forging the body are 'moving', and the last realm of refining is 'quiet'.

Therefore, this turtle breath practice is a method of meditation and exhalation, which guides the qi and blood strength to cleanse the viscera through breathing and exhalation, eliminate impurities and toxins in the viscera, and improve one's own physique.

As the saying goes, it is a three-point poison.

Martial arts cultivation, as long as you take the secret medicine of cultivation, will more or less accumulate some toxins in the body, and the first step in cleansing the viscera is to eliminate the toxins of the viscera and increase the vitality of the viscera.

As the practice deepens, it strengthens the internal organs, makes them tougher, improves digestibility, and resists toxicity.

Chen Xuan had already memorized the cultivation method of the Turtle Breath Cultivation Dirt Technique, and now he looked through it just to make sure that it was foolproof, after all, there was no room for sloppiness in refining the Dirty Exercises.

Soon, Chen Xuan finished reading the cheats of the Turtle Breath Refining Dirty Skill.

Closing the cheats, Chen Xuan sat cross-legged and began to practice according to the method of breathing and breathing in the Turtle Breath Cultivation Technique.

Immediately, Chen Xuan's whole person seemed to be 'quiet' all of a sudden, and his strong qi and blood were restrained like waves, becoming calm, and his breathing became nothing.

Under the Turtle Breath Refining Dirty Technique, the surging qi and blood became gentle, and the strength became docile, and as Chen Xuan breathed and exhaled the qi and blood strength under his control, it moistened the viscera like a spring breeze and rain.

It's a very slow process.

It took half an hour for the qi and blood strength to wrap the five internal organs little by little, and then under Chen Xuan's careful control, the qi and blood strength began to slowly penetrate into the five internal organs, trying to refine the internal organs subtly.

"Boom!"

As soon as Chen Xuan tried to refine his viscera with subtle qi and blood, he felt a burst of pain coming from his viscera.

The viscera is too fragile, although it is only a faint wisp of qi and blood strength, it still puts the viscera under great pressure, but this pain is still within Chen Xuan's tolerable range.

Although it is said to be tempered, it is quite gentle compared to using strength to quench skin, flesh and bones.

With the passage of time, Chen Xuan gradually adapted to this kind of tempering.

"Hoo ......"

Two hours passed, Chen Xuan felt that the endurance of his viscera had reached the limit, and he began to slowly withdraw his qi and blood, ending this cultivation, and then let out a long sigh of relief.

In a flash, he opened the data panel.
