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

The Extreme Body Forging Method is divided into three volumes.

The upper volume is for external refining, the middle volume is for internal refining, and the lower volume is for marrow refining.

The refining here is naturally to train the three marrow of human beings.

《"Shuowen Jiezi" says:"The marrow is also the fat in the bones."《"Suwen" of"Huangdi Neijing"."Pulse Essentials Essence Theory" states:"The marrow is the filling of the bones."

""Marrow" is a paste-like substance distributed in the bone cavity. According to the different locations where the marrow is distributed, the marrow is divided into three types, namely brain marrow, spinal cord, and bone marrow. What is hidden in the brain cavity is called brain marrow; what is hidden in the spinal cord canal The spinal cord is called the spinal cord. The spinal cord goes up to the brain and down to the tail and sacrum; what is hidden in the bone cavity is the bone marrow.

Modern medicine has a more detailed explanation of the three marrow of the human body.

The brain is the central nervous system of the human body and controls the body. All physiological activities and metabolic functions of all organs and tissues.

It not only directs people's thinking, language and actions, but also controls the body's own immune system, and the body's immune system is its own best doctor, and is related to anti-disease and anti-aging. It has a direct effect.

The spinal cord is part of the central nervous system and has reflex and conductive functions. All human actions must be completed by the conduction of spinal nerves.

If the number of spinal cord cells in a person decreases, slow reaction, slow movement, and waist and back pain will occur. When the spinal cord is interrupted or damaged, the lower limbs will be paralyzed.

Bone marrow is very important for maintaining the body's life and immunity. It is the body's hematopoietic center, immune center and bone metabolism control center.

In addition to being responsible for hematopoiesis and nourishing bones, In addition, it is also the central immune organ of the body. The white blood cells produced by the bone marrow can enable the body to resist the invasion of germs, while the immune T cells, B cells and NK cells can enable the body to have normal immunity to disease and can respond promptly and quickly. Kill tumor cells and avoid the occurrence of tumors; bone marrow also induces the production of anti-aging active enzymes such as SOD, bone peptide, glycopeptide, peroxide, and enzymes, which can resist and buffer the loss of aging factors such as free radicals, thereby delaying aging.

There is no bone marrow The human body will not be able to make blood, will lose immunity, and of course there will be problems with the bones.

The"three marrows" of the brain, spinal cord, and bone marrow not only perform their own duties, but also cooperate with each other to form the core of life of the human body and control the function of all the organs of the human body. Physiological activities, coordinating the limbs to carry out various daily activities, are the foundation of human life and health.

There is no need to say more about the brain and spinal cord parts for now.

Because the marrow refining roll is similar to the external refining roll, they both require step-by-step exercise.

The bone marrow is the marrow refining. The first part of the volume that needs to be exercised

"For the content of bone marrow exercise, I refer to the"Yi Jin Jing" and"Marrow Cleansing Jing". After the bone marrow exercise is completed, it will not only have the effect of Yi Jin Jing and marrow cleansing, but also can further eliminate toxins and impurities in the body. It can also greatly Significantly enhance the body’s immunity"

"And according to the function of bone marrow, I also integrated the content of the blood refining chapter into the bone marrow."

"Because bone marrow is the hematopoietic center of the human body, after exercising the bone marrow to the extreme, it can produce healthier and more nutritious blood. Gradually replacing old blood with new blood can produce the effect of blood transfusion."

"Exchanging blood means refining blood!"

"After the blood transfusion is completed, the new blood will contain a large amount of substances that slow down aging, allowing me to live longer."

"Ease tendons, wash marrow, refine marrow and exchange blood"

"This is the effectiveness of bone marrow training"

"The former further strengthens the body, eliminates toxins and impurities, and improves immunity."

"The latter enhances self-healing ability and delays aging, which in a sense improves vitality."

"I can't wait to train my bone marrow to the extreme."

After taking one last look at himself in the mirror, Bai Xuan left the bathroom.

He became more handsome again.

But there was no fundamental change.

"Let me test my current strength first"

"Then prepare medicine to nourish the bone marrow."

Coming to the boxing dynamometer, Bai Xuan clenched his fists

"upbraid!!!"

Speech and tongue, breathing, heartbeat, skin, flesh, muscles and bones, internal organs...qi, sound, blood...are perfectly combined to condense the power into one force!

"Bang!!!"

The fist hit the boxing dynamometer between lightning and flint.

Six hundred and fourteen kilograms!"

"It's really terrifying power. It seems that it won't be long before my strength will be twice that of the world record."

Of course,

Bai Xuan also knows that the strength of six hundred and fourteen kilograms is very powerful for us humans.

But a tiger has a force that exceeds a thousand kilograms.

A slap of an adult brown bear has a force of one thousand six hundred kilograms. A strength of about kilograms.

My current strength is nothing.

"Set a small goal first"

"Before the end of the next semester, you will have the combat power to kill a tiger with your bare hands."

According to Bai Xuan's calculations, Bai Xuan can probably complete the Marrow Refining Chapter in one semester.

By then, he will probably have the combat power to kill a tiger with his bare hands.

Then, it will be time for him to explore extraordinary power.
