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

The Extreme Forging Method is divided into three volumes.

The upper volume is the outer refining, the middle volume is the inner refining, and the lower volume is the refining of the pith.

The refining of the marrow here is naturally the exercise of the three marrows of people.

"Shuo Wen Jie Zi" cloud: "The pith, the fat in the bones." "The Yellow Emperor's Neijing" of "Su Wen Pulse to Subtlety" said: "The marrow is the filling of the bone."

"Medulla" is a paste-like substance distributed in the bone cavity, and according to the different parts of the medulla, the medulla is divided into three types, namely cerebral medulla, spinal cord, and bone marrow.

Those hidden in the cranial cavity of the brain are called cerebral marrow, those hidden in the spinal canal are called spinal cords, and the spinal cord leads to the cerebral medulla and runs down to the caudal sacral, and those hidden in the bone cavity are called bone marrow.

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

The cerebral spinal cord is the central nervous system of the human body, which controls all the physiological activities and metabolic functions of all organs and tissues of the body.

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

The spinal cord is a part of the central nervous system, which has reflex and conduction functions, and all human behaviors and actions must be completed by the conduction of spinal nerves.

If the number of cells in the spinal cord decreases, there will be slow reactions, slow movements, weakness in the waist and legs, and the spinal cord will be interrupted or damaged, and the lower limbs will be paralyzed.

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

In addition to being responsible for hematopoiesis and nourishing bones, it is also the body's central immune organ, the white blood cells produced by the bone marrow can make the body resist the invasion of germs, and the immune T cells, B cells and NK cells can make the body have normal immune disease ability, and can kill tumor cells in a timely and rapid manner to avoid the occurrence of tumors;

The bone marrow also induces the production of anti-aging active enzymes such as SOD, osteopeptide, glycopeptide, peroxide, enzymes, etc., which can resist and buffer the loss of aging factors such as free radicals, thereby delaying aging.

Without bone marrow, the human body cannot make blood, and it will also lose immunity, and of course, bones will also have problems.

The "three marrows" of cerebral spinal cord, spinal cord and bone marrow not only perform their own duties, but also cooperate with each other, constitute the core of human life, control the physiological activities of all organs of the human body, and coordinate the limbs to carry out various daily activities, which is the foundation of human life and health.

The cerebral and spinal cord parts don't need to be talked about for the time being.

Because the refining volume is similar to the outer refining volume, it needs to be exercised step by step.

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

"The content of the bone marrow exercise, I refer to the "Yi Jin Sutra" and "Washing the Bone Marrow Sutra", after the bone marrow exercise is completed, it will not only have the effect of Yi Jin washing the marrow, but also further eliminate toxins and impurities in the body, and can greatly enhance the body's immunity. "

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

"Because the bone marrow is the hematopoietic center of the human body, after the bone marrow is exercised to the extreme, it can produce healthier and more nutritious blood, and gradually replace the old blood with new blood, which can produce the effect of exchange transfusion. "

"Changing blood is refining blood!".

"After the exchange transfusion, the new blood will contain a lot of anti-aging substances, which will allow me to have a longer life. "

"Easy tendon to wash the marrow, refining the marrow for blood. "

"That's where bone marrow comes in. "

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

"The latter enhances self-healing and slows down aging, in a sense, it improves vitality. "

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

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

I'm a little more handsome again.

But there is no essential change.

"Let's test my current strength first. "

"Then I went to make a medicine that nourished the bone marrow. "

Coming to the boxing force tester, Bai Xuan clenched his fists.

"Zha !!".

Mouth and tongue, breathing, heartbeat, skin, flesh, muscles and bones, internal organs...... Breath, sound, blood... Perfectly combined, so that the power is cohesive!

"Bang !!".

The fist hits the boxing dynamometer between the electric flashes.

Six hundred and fourteen pounds!

"It's terrifying, it doesn't seem to be long before I'm able to double the world record. "

Absolutely

Bai Xuan also knew that the power of six hundred and fourteen catties was very powerful for me humans.

But with a slight wave of the tiger, it has the power to surpass a thousand catties.

A slap from an adult brown bear has a strength of about 1,600 catties.

The power of oneself now.

It's nothing.

"Start with a small goal. "

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

According to Bai Xuan's calculations, one semester will probably allow Bai Xuan to complete his cultivation of the marrow refining chapter.

When the time comes,

You will probably be able to have the combat power to kill the tiger with your bare hands.

Then,

It's time to explore the supernatural power yourself.
