The path of body refining in this world, like the cultivation of the gods, has gradually declined, and the martial artists who specialize in this system have basically disappeared.

However, according to legend, in ancient times, the martial artist was one and three cultivators, and it was a real three-line initiate, going hand in hand, and there would be no distinction between body, element, and god at all. It's just that after the drastic changes in heaven and earth and the long war with foreign races, with the gradual reduction of cultivation resources and the loss of various powerful inheritances, martial artists began to abandon the two ways of refining the body and the spirit that were more difficult to cultivate, and gradually, Yuan Force cultivation became the mainstream.

Meng Nan's cultivation of Haoran righteousness, can achieve the true sense of the three line of initiates, a long time of cultivation, so that his physical strength, also naturally reached the level of triple bone refining, coupled with the previous heavenly tribulation tempering, at this time has approached the peak of the bone refining realm, a punch, can burst out of a huge force close to 10,000 catties, compared to the same level of martial artists, I don't know how much stronger, even with his physical strength at this time, the strength of the body, has been able to match the martial artists of the Earth Evil Realm.

The third level of refining the body is refining bones, while the fourth is refining skin.

This realm is an important watershed for body refining martial artists.

Martial artists who have reached the realm of skin refining, the skin membrane of the whole body will become extremely tough, and the sword will be difficult to hurt, which can greatly enhance the defense of the warrior, and the strength will also explode, and every time you break through a small realm, you can increase the terrifying power of five thousand catties, as for the refining of the skin after the refining of the marrow realm, it will be even more terrifying, and the breakthrough of a small realm can increase the strength of ten thousand catties!

For a true body refining martial artist, reaching the skin refining realm can be regarded as having the capital to compete with other martial artists.

However, the further back you go, the more difficult it will be to break through, and the more resources you need. The massive amount of heavenly and earthly treasures is simply not something that ordinary martial artists can afford, and this is also an important reason for the decline of the refining body.

The effort is not proportional to the return!

Nowadays, very few people have put a lot of effort into refining their bodies.

Most of the body refining martial artists are poor people from poor families, and they can only stay at the bottom of society and do some physical work that relies on their bodies to eat.

There are very few body refining martial artists who can reach the skin refining realm.

At this time, Meng Nan's physical body was constantly moving towards the Skin Refining Realm under the tempering of the thunder liquid, but the pain he endured was unimaginable.

In the thunder liquid, there are two extreme powers: destruction and life.

The power of destruction is constantly destroying, and the power of life is responsible for repairing, breaking and standing, making Meng Nan miserable.

The bones are broken apart and then put back together.

It was a heart-wrenching pain!

Into the soul!

Meng Nan's whole body was soaked with sweat, as if he had just been fished out of the water, his body kept swinging, and the terrible screams of beasts continued to roar from the depths of his throat, echoing in the silent mountains and forests.

Desperately guarding his mind and enduring the severe pain in his soul, but the constant sound of bones breaking from his body made him almost collapse several times.

Meng Nan felt that even if it was the harshest punishment for a vicious person who fell into hell, he was afraid that it would not be more than that, right?

Who can understand the terrifying feeling of watching every inch of bone in his body slowly shatter and reorganize, and then reorganize and reorganize?

Under the torture of this inhuman pain, the bones of Meng Nan's whole body have been tempered countless times, and they have gradually become extremely tough, as if they were jade.

Bone like jade!

The sevenfold pinnacle of the Bone Refining Realm!

At this time, the muscles and bones in Meng Nan's body have become extremely tough, not to mention ordinary swords, even if it is a real spirit weapon, a slightly weaker one may not be able to cause harm to him.

The hardest stage has finally passed.

Meng Nan recovered from the endless pain and breathed a sigh of relief, but then smiled bitterly.

Because after refining the bones of his body, the thunder liquid in his body began to shift its target, and it poured towards his body surface one after another!

In an instant, countless cracks like spider webs appeared on the skin on Meng Nan's body, and red blood oozed out, making him instantly become a bloody man!

Pain!

Heartbreaking!

"Ahh

Meng Nan screamed out, and his scalp was already cracked.

The life force in the thunder fluid then poured out, repairing the cracked skin on his body.

Immediately afterward, he began another painful experience.

Gradually, Meng Nan became numb.

I only know that I am desperately urging Haoran to be righteous, so that my pain can be alleviated, even if it is only a little relief, it can give him a chance to breathe.

Meng Nan finally understood why the path of refining the body would be abandoned by people.

Not only does it require huge resources, but the more important reason is probably because of the process of refining the body...... It's so painful!

Those who are a little weak-willed are afraid that they will be directly tortured to the point of madness!

Meng Nan's body formed a thick layer of blood scabs.

The skin on his body gradually became tougher.

Refining Skin Realm is a heavy heaven!

Refining Skin Realm Double Heaven!

......

More than half an hour later, when he reached the Fourth Heaven of the Skin Refining Realm, the thunder liquid in his body was finally exhausted.

Call!

Meng Nan exhaled heavily, his heart palpitating.

It's finally over!

At this time, if he is asked to do it all over again, I am afraid he will not have the courage to swallow the thunder night!

He adjusted his breathing, urging Haoran to breathe.

After a moment, he slowly opened his eyes, and two sharp lightning bolts burst out.

Gently moved his body, and the blood scabs that had coagulated on his body suddenly fell off, these were all dirty blood and impurities in Meng Nan's body.

Grow up.

Meng Nan glanced around, and his gaze suddenly stopped on a huge mountain rock not far away.

The foot slammed on the ground.

Bang!

The huge force suddenly left a deep footprint on the ground, and then his figure roared out, and in a flash he was already in front of the mountain rock ten zhang away.

Shen waist twisted his body, punched, and blasted out with great force.

Rumble!

An amazing scene has appeared!

With a loud bang, the mountain stone, which was two or three zhang high, like a small mountain stone, was directly smashed into pieces by Meng Nan's punch!

"What a powerful feeling!"

A touch of ecstasy passed over Meng Nan's face, with the punch just now, he didn't use Haoran righteousness, with pure physical strength, he was already terrifying.

The pain just now was indeed not in vain.

Refining Skin Realm Four Heavens!

30,000 catties of power!

With the strength of his physical body alone, he was already able to compete with ordinary Tiangang Realm martial artists!

Meng Nan nodded with satisfaction.

Next, it's time to go back to the assessment.

I don't know if those guys have passed the first level.

Thinking that he was forced to flee for his life by Li Tianjun and others, Meng Nan's eyes couldn't help but flash a touch of gloom.

Lao Tzu is coming back, are you ready to be abused?
