Outside, there are twelve hours in one day. Now, more than nine hours have passed, and more than two more hours have passed, and the whole day has passed.

Within the century-old secret realm, seventy or eighty years have passed, and about twenty years are left, which is one hundred years.

At the huge waterfall, the sound of water is still there, rumbling like the galloping of thousands of troops, and the huge force of millions of kilograms is enough to smash everything.

Chu Mu was not seen by the big pool.

After a closer look, there seemed to be a figure in the huge waterfall, standing on a large stone under the waterfall, naked, allowing the fallen waterfall to impact and resist the huge force of millions of pounds.

Chu Mu, using the most primitive method, is tempering his holy body.

Strictly speaking, Chu Mu is a practitioner of the three-level practitioners of Yuanli Flow, Holy Body Flow and Yuanshen Flow. At present, he has suitable Yuanli Flow practice techniques and suitable Yuanshen Flow practice secret techniques. However, the lack of the Holy Body practice techniques of Holy Body Flow, which has led to his holy body being unable to improve.

The current environment is pretty good.

A hundred years within the secret realm is equivalent to a hundred years of cultivation here in seclusion. In theory, if you specialize in one of them, you will get huge and unimaginable improvement.

This is not the case in actual practice.

If you practice one of them for a period of time, you will reach a bottleneck. If you continue to practice, you will not only fail to break through, but will instead make people feel tired and bored, which will be even more unfavorable.

At this time, you must give up temporarily and turn to practice other things.

Only by alternating and combining different practice contents can people maintain courage and diligence.

Chu Mu understood this deeply. Therefore, he would not deliberately practice the Shenhuang Sword Yuan, but alternated in various aspects such as the cultivation of sword techniques, creation, understanding of sword heaven and earth, application of the mysterious method of the Yuan Dynasty, tempering of the holy body, etc.

Of course. If it is used to transform the power of rules into the power of laws, it may be very fast at the beginning, but with the more power of heaven and earth transformed, the slower the speed and greater the difficulty. At that time, a hundred years may not be enough to transform one of the power of rules into the power of laws.

Therefore, no one will deliberately use all this hundred years to transform the power of rules. At most, it will transform into one or two types, and it will take more than ten years, twenty or thirty years.

Chu Mu did not have such a choice. The more he practiced, the more he studied the ancient swordsmanship, and Chu Mu felt more and more that the power of heaven and earth seemed to be not a necessity of swordsmanship, and it seemed that it was optional.

He didn't know whether this was an illusion or a reality. After all, since he entered the cultivation stage to the present, the knowledge he received, the inheritance and knowledge he received were full of the combination of the application of the power of heaven and earth and the sword technique. The two seemed to be complete and inseparable.

Furthermore, now, Chu Mu's swordsmanship does need to be integrated into the power of heaven and earth in order to fully exert its power and become more powerful.

Fortunately, Chu Mu's own sword stance was different from the sword technique he had practiced before, and there was no fixed type of power of heaven and earth that he had to use. In other words, the three powers of law he now mastered can be integrated into his own sword stance.

The huge impact force of millions of kilograms of waterfall continued to impact Chu Mu's body. Every inch of skin and muscle almost brought heavy loads under the impact of this terrible force.

Chu Mu controlled every muscle of his own, vibrated at high frequency in a vibration manner, fighting against the huge impact of the waterfall, and also used this huge impact force to temper the muscles, temper the film, carry the impact force into the body, temper blood, bones and internal organs, etc.

The shock force, Chu Mu is currently only at the third level, that is, the level of the shock force. The shock force can no longer be of much help to his current strength, unless he is promoted to the level of the shock force, but it is not easy to improve from the shock force to the shock force, on the contrary, it is very difficult.

Chu Mu had no path to his predecessors, no experience to refer to, no one could give him guidance, and he could only rely on his own understanding and constant exploration. He didn't know how much time it would take to improve the earth-shaking force into a more powerful earth-shaking force.

Too much practice, too much ability to improve, but time seems limited. Chu Mu can only make some choices temporarily and choose aspects that can improve his strength more intuitively and quickly to focus on cultivation. Such abilities as Earthquake, which require a lot of time and energy to practice and explore, but do not know when to improve, can only temporarily let go.

Although the earth-shaking force is not enough to deal with the Saint-level powerhouses and is used to temper the body, it can still play a good role.

Every muscle is shaking, resisting, and recoiling, causing every part of the body to fluctuate inside and outside, and is tempered and enhanced in the vibration.

When Chu Mu felt pain in every part of his body, he stopped practicing. With a bang, he rushed out of the waterfall. In the air, the stars robe had already covered his whole body.

After landing, use the Shenhuang Sword Yuan to relieve the aching pain all over the body. After recovery, draw the sword and swing it out with one sword.

The sword energy shot and exploded. Countless shattered sword energy dispersed, covering a range of 100 meters. With the invisible center, a sword energy storm formed, which was stormed wildly, and could tear everything in the storm to pieces.

From the size of more than ten meters when I started practicing to the size of a hundred meters now, both the coverage and lethality have been greatly improved.

But this is not enough, it can be more powerful.

After a storm sword move, Chu Mu collected his sword and concentrated his energy. Then, the splendor flashed through his eyes, and the sword swung forward. He saw the invisible sword light shooting away, stretching and extending rapidly, turning into a white sword light as thick as a finger, as if the one connected by water and sky, had no beginning or end, and was like a whole.

A single-line sword style!

Chu Mu also practiced this move for a long time and mastered the essence of it.

The white sword light as thick as a finger was cut on the huge waterfall. In an instant, a shocking scene appeared. The huge waterfall was cut off under the white sword light as thick as a finger.

However, the impact power of millions of kilograms is still very powerful, and the power of the first-line sword style is not enough and has not been fully exerted. Therefore, it only supports only two breaths, and there is also the contribution of the eternal sword intent.

Two breaths may seem very short, but you should know that this huge waterfall and the water flow downwards carry terrifying power, and each time it is as many as millions of pounds, and under bombardment, it cannot last long.

Taking a deep breath, shaking his wrist gently, and under the tip of the sword, Chu Mu's strength was injected into the sword body under the control of the eternal sword intent, reaching the tip of the sword. With the tip of the sword, the force condensed into one, turned into a half-meter-long sword light, and shot out like a crescent moon. The speed was extremely fast and extremely amazing.

If you use sufficiently powerful soul power to cover it, you will notice that the sword light is flowing, constantly flowing, forming a complete cycle, just like a chainsaw.

There was a light puff, just a flash, and the crescent-moon-like sword light instantly broke through a large amount of waterfall flowing, and shot deep into the mountain wall behind the waterfall.

The mountain wall behind the waterfall has been washed away by the waterfall for many years and has become very hard, and the ordinary attacks are completely unharmed, but under the light of the crescent sword, it is constantly cut, as fragile as tofu.

Chu Mu's soul power ignored the obstacles of the waterfall and "sees" the gap cut by the crescent-like sword light, which is several meters deep.

Continuously practiced the Storm Sword Style, the First-Search Sword Style and the Sky Cut Sword Style. It was not until the Shenhuang Sword Yuan was exhausted that the Yuan Dan was taken out to restore the Sword Yuan. The Sword Yuan was also tempered and slightly improved in this way of restoring consumption.

With the understanding, the mystery of the sword heaven and earth was revealed to Chu Mu's mind at a deeper level. Chu Mu also discovered that the sword heaven and earth seemed to be as vast as the heaven and earth, endless. No matter how he comprehends it, he could not fully comprehend it.

The improvement of the three self-created sword poses, the cultivation of the three sword qi attack sword poses, the understanding of the true meaning of the sword qi, the tempering of the holy body, the understanding of the sword heaven and earth, the attempt of the mysterious method of the soul, the study of the heavenly spirit, the understanding of the essence of sword craft, the deep mastery of the sword craft, etc., are all within Chu Mu's cultivation range, alternate rotation.

This alternation will make Chu Mu's cultivation more efficient, and there will be no one that cannot be improved on the one hand, but there is nothing else to practice, so he can only waste time by slack.

Year after year passed.

Chu Mu finally mastered the essence of the three major sword energy attack sword style and derived his own insights. After that, he realized the true meaning of the sword energy.

At this time, he began to create his own sword energy attack sword style.

It's more difficult.

The Storm Sword Style is a group attack, the first-line Tianjian Style is a lateral attack, while the Tianqi Sword Style is a single attack, and Chu Mu must have a choice.

This is not like the three sword poses that were originally tattooed.

Groups and monomers are originally two ways.

The cultivation level has improved, the holy body has become stronger, the soul has become more condensed, the sword skills have become more advanced, and the sword style has been created has gradually become perfect. Everything is improving in the best direction.

Before he knew it, Chu Mu also discovered that time seemed to be coming.

There are only a few short days left in the secret realm for a hundred years.

Chu Mu did not rush to practice anymore, but stood under the impact of the waterfall, calmed down and realized the past nearly a hundred years of cultivation, and made a summary.
Chapter completed!
