The sword sprinkling autumn water was able to attract Su Mu's attention, obviously not because of how profound the move itself was.

In the current Su Mu's opinion, even if it was the original sword dance of the Nine Heavens, it could not be regarded as such a subtle sword move.

The more you know, the higher your natural horizon will be.

And the reason why Su Mu was very interested in sword sprinkling autumn water was actually for another move, a move that had been bothering him for a long time, Wan Yan Thunder.

Compared to the blue sky shadow, the connotation of Wan Qi Lei's moves is actually relatively easy to understand. Using his true qi as a guide, he triggers a violent reaction of static electricity in the air around him, thus creating thunder out of nothing.

It sounded simple, but Su Mu knew how difficult it was to actually do it.

The first thing that is difficult to overcome is the quality of one's true qi.

In short, Su Mu's own True Qi was simply not enough to produce such a complex external change. It can be very difficult to stay in the body for a long time.

The reason why Su Mu was able to successfully use the half-finished "Ten Thousand Thunder" last time was that there was a strong enough thunder in the sky, which allowed him to skip the complicated first step and directly enter the second step, that is, to control the thunder to attack the enemy.

Just like this, he was tired and half dead, and in two or three strokes, he almost emptied all his true qi.

And Su Mu still knew very well in his heart that when Taibai Zhenyi manipulated his body to use the Ten Thousand Thunders, the power of the thunder was not inferior to the thunder of nature at all.

How huge is the reserve of true qi that human beings need to turn into the power of nature?

Now Su Mu's True Qi Realm is about the peak of the Tongmai Realm, and although it is already quite terrifying in the same age, it is still not comparable to the top disciples in the super large sect.

Since they were children, they have had a master who broke through the Sky Realm and even the Divine Retention Realm to smooth their pulses every day, practiced the highest quality internal strength and mental method, and took elixir and immortal medicine, and the gap between the accumulation of this foundation is too big.

And Su Mu obviously didn't have such good objective conditions, even if his body was a rare strong meridian in the world at this time, there was no shortcut to the accumulation of true qi.

Su Mu knew this truth very well, so he himself was a little helpless, but he really didn't want to give up.

Su Mu admits that he is not a person who is too ambitious and impatient, but he knows that if he improves his True Qi realm step by step, by the time he can successfully use the Ten Thousand Thunders, he is afraid that he will already become a middle-aged man who has passed his age.

Such a treasure, the supreme swordsmanship was placed in front of Su Mu, but he couldn't practice it, which really made him uncomfortable.

Therefore, Su Mu, who was full of curiosity, racked his brains all the time, thinking about what other way he could use the trick of Ten Thousand Thunders. He also went to the library to see if there were any moves that were more similar to Wan Qilei that could be used for reference.

The sword sprinkled autumn water at this time, and it was at this time that it came into his eyes.

Strictly speaking, the sword sprinkled autumn water and the ten thousand thunder are far away in terms of quality and profundity, and the eight poles can't hit the edge.

After studying the Sword Technique, Su Mu knew that the moves like the sword sprinkling autumn water and the sword dance for nine days were different in nature.

Sword moves can be broadly divided into two categories, Sword Sect moves and Qi Sect moves.

The sword sect's moves are based on the sword shape, supplemented by true qi, and mainly pay attention to the changes in the sword path and sword momentum.

The Qi Sect moves are just the opposite, the true qi is the foundation, the sword shape is supplemented, and there is no need for the actual sword shape, and the true qi is used to increase the power of the sword so as to hit the opponent more effectively.

The sword sprinkling autumn water is a typical air-sect move. Its essence is to let its true qi disperse and turn into a mist and cling tightly to the sword body, thereby increasing the striking area of the sword.

When swinging the sword, the true qi attached to the sword body will occasionally be sprinkled in the air like water droplets, which is crystal clear and very beautiful, hence the name, "sword sprinkled autumn water".

Su Mu was interested in it not because of how profound it was, but simply because the sword sprinkling autumn water was the first Qi Sect move that Su Mu had come into contact with.

There is no need to swing the sword, and there is no specific sword shape, just a simple change in the nature of the true qi in the body.

From this point of view, it also has a bit of similarity with the Ten Thousand Thunders that turn into thunder with true qi.

Thinking of this, Su Mu was ready to start experimenting, Su Mu always lacked curiosity about everything, just like when he studied the dismantling method of low-level moves.

Looking at Su Mu, who rushed to the back mountain, Otoba, who was originally practicing swords, was also surprised, and he had never seen that calm and introverted senior brother like this in his memory, as if a child had got a very fresh toy and wanted to try it impatiently.

"Brother Mu, didn't you say that you were reading in the library building, why did you come so early today?"

"I've found a new move, and I want to give it a try!"

"What is it, did you see it in the library?"

"Well, it's a high-level sword move, and the sword is sprinkled with autumn water. ”

After that, before Yin Yu could continue to ask, Su Mu had already stood still, held his breath and concentrated, and slowly released the true qi in his body little by little.

Seeing that Su Mu suddenly entered a state of concentration, Otoyu consciously flashed to the side.

Otowa had also heard of the sword sprinkling autumn water, but the difficulty of the Airben's moves was already higher than that of the Sword Sect, so he hadn't dabbled in it at this time. Now is a good time to watch.

True Qi poured into the sword body little by little along Su Mu's hand, and a faint white light gradually appeared on the sword.

Su Mu kept imagining the true qi form of the sword sprinkled with autumn water mist in his mind, and little by little he tried to transform the true qi on the sword into the form he imagined.

In fact, this step is quite difficult.

Even if it is a sect that specializes in Qi Sect moves, it is impossible to expose disciples to such complex changes in true qi as soon as they come up, and generally let disciples start by stabilizing the scattered true qi first, and only after they have a solid enough foundation and have a certain level of control over true qi will they make a targeted attempt.

And the form change of this sword sprinkling autumn water is not simple in the airsect moves, the general form change is at most to transform the true qi into a shape, and it takes a strong imagination and control to make the true qi transform into a mist according to one's own mind.

It's hard to return, but the result is still no different from the previous high-level sword moves.

After knowing the basic rules, Su Mu successfully used the sword to sprinkle autumn water on his first attempt. The true qi that was originally wrapped around the sword's body gradually turned into a trace of mist, slowly enveloping the entire sword tightly.
