Sun Ning's hand, which had already made a forceful action, immediately retracted.

There was surprise in his eyes.

"What's going on? To push this door open, you have to reach the Divine Sea Realm to cultivate?"

Sun Ning thought in surprise, but his brows furrowed.

The mysterious mission was done, and Sun Ning was far from being ignorant at the beginning.

You must know that this is very likely to be a major event that has been planned by a traitorous and evil person like Emperor Wei for decades, and in the end it still fails, which will cause an earthquake on the entire continent.

From Qin Meiren to the Purple Kite Holy Maiden of the Shendan Palace, they have also paid at least several years of hard work for this.

If you think about it again, there are even a lot of people who are directly or indirectly involved in this matter.

Now, to open a door, the system actually prompts that you must first upgrade your cultivation to the Divine Sea Realm.

For the God of War system, Sun Ning trusted him very much in his heart.

It can't give such a prompt for no reason.

This shows that in the secret room under the Qingsi Well, after easily obtaining four Sun and Moon Stones, the stone door that he had to push open was full of danger.

"If you want me to raise my cultivation to the Divine Sea Realm, it's not too difficult!

Sun Ning frowned and muttered, "But in this case, I will not be able to reach the peak and most perfect state of the Innate Realm, and it is very likely that I will not be able to achieve the unity of heaven and man!"

If he wants to give up the unity of heaven and man now, he can't!

Even if he gives up this mysterious mission, Sun Ning must achieve the unity of heaven and man.

Although he is far from the unity of heaven and man, he is only one layer of window paper, and he is only one chance to break it.

But when this opportunity will come, Sun Ning doesn't know.

It could be now, it could be a few months from now.

Just when he was at a loss, he heard Qingtong say: "Master, your current cultivation is extremely close to the peak of the innate realm. There is only one last step left, and you can advance to the legendary Wonderland, where heaven and man are one!"

Sun Ning said: "Not bad!"

Qingtong said: "The master has raised the 'power' to the extreme. The owner's skin, tendons, meridians, veins, and bones, although they have also reached a height that ordinary people cannot reach, are not in the most perfect state. If the master can refine it again, maybe he will be able to break through the shackles completely!"

Sun Ning's eyes lit up and said, "How to refine, do you know?"

Qingtong said: "I know a "Hundred Refining Martial Arts", which is dedicated to refining every part of the martial artist's body! Master, wait a minute, I will write this classic silently!"

Sun Ning was overjoyed.

Half an hour later, Qingtong had already written down a 100-page classic in great detail.

Sun Ning opened it and saw that in this hundred refining martial arts, there were various methods starting from the skin membrane, then to the muscles, bones, meridians, and spirits, each of which was extremely extraordinary, and he was immediately overjoyed.

He started from the first step, refining the 'skin' first.

Refining skin, the cultivation is the green python skin technique.

The green python skin transformation technique is to molt the skin of the python year after year, take its essence, and turn it into exercises.

The skin and flesh of the whole body, from head to toe, began to tremble slightly, stretched slightly, and stretched slightly, gradually, and began to expand slightly, and finally as soft and flexible as cotton......

After cultivating the green python skin transformation technique with great difficulty, Sun Ning's face was almost distorted.

When you practice this exercise, you will suffer from the pain of skinning, and the pain will be unbearable!

"This green python skin transformation technique is so painful to cultivate, if you succeed in cultivating, I'm afraid it will really make me take off a layer of skin!"

Sun Ning gasped, if he hadn't been in a hurry, he would never have practiced this kind of exercise that was almost masochistic.

"By the way, it is rumored that the Sun Moon Stone can help cultivate all kinds of extremely difficult exercises......"

Sun Ning's eyes lit up, and he placed the four sun and moon lamps around, and once again launched the green python skin transformation technique.

This time, the pain caused by the practice was greatly reduced!

"The effect of the Sun Moon Stone is not only speeding up the operation of internal breath, but also greatly reducing the pain when practicing certain exercises!

This experiment gave Sun Ning an understanding of the efficacy of the Sun Moon Stone.

After cultivating the Green Python Skin Transformation Technique more than a dozen times in one go, Sun Ning only felt that his body was extremely tired, so he took out the Eastern Emperor Visualization Scroll and began to cultivate his spiritual power.

At some point, in that whirlpool, a red dot gradually stood out.

The bizarre state reappeared.

Sun Ning clearly felt that his spiritual power began to grow stronger, like a seed buried in the ground, pulling out tender green buds, trying to break the shackles of the soil.

In the entire secret room, every place, even the slightest detail, was clearly reflected in his soul and mind. The invisible undulations and fine lines on the stone wall are so clear......

Five times the time to accelerate down, three days later.

"After the skin refining is completed, it is the forging of 'tendons'. ”

After three days of penance, Sun Ning cultivated his spiritual power while refining skin, and felt that he had improved again.

The way of refining tendons, tendons like silk is the highest realm.

For warriors, tendons are the transmission veins of the whole body's strength.

If the strength of the human body is a total of 1,000 catties, because of factors such as force control, conveying method, tendon tolerance and dispersion, a punch is blown, and there are only 200 catties left at most.

Refining tendons is to gather the strength in the body as much as possible to one point, ten percent of the strength, and at least ninety percent of the punch is left.

There are three ways to refine tendons.

The first is to improve the flexibility of the tendons.

The second is to gradually separate the tendons, generally speaking, one tendon is separated into six, which is the day when the second stage is completed.

The third is to temper and compress the separated tendons again, as fine as silk, and then compress the tendons as thin as silk tightly, on the surface, the thickness is equal to the thickness before tempering, but in fact, its strength is divided into six, and the delivery force of each root is roughly the same as before the tempering, and the six are combined into one, and the immediate increase is several times.

Correspondingly, there are three major exercises for the three methods of refining tendons, which are "Silk Stretching", "Cocoon Stripping and Wire Separation" and "Jade Silkworm Adhesion".

Sun Ning slowly unfolded the silk stretching technique.

According to the description in the scriptures, the intense pain of refining tendons makes people shudder just thinking about it.

Just imagine, stretching the tendons that connect the flesh and blood around the body, how can it not hurt!

Martial arts are difficult, and many people are not not talented, but they are afraid of unbearable pain when they practice hard again and again, so they give up. Those who have cultivated to a high level, which one is not a person with a strong heart.

The pain gradually spreads from under the flesh to the whole body......

Two hours later, Sun Ning had practiced the silk stretching technique from beginning to end, and he couldn't help but let out a sigh of relief, with fine beads of sweat oozing from his forehead.

And yet—

When I practiced, I still had pain, but it was not the same as the painful feeling of dying and living as described in the scriptures. Even, it is much less than when I first practiced the green python skin technique.

"Sun Moon Stone is really a big baby!" Sun Ning felt a burst of ecstasy in his heart.
