For a while, the bedroom fell into dead silence, and Du Mu sat at the desk, looking at the computer with a changing expression.

"It seems that the realm of swordsmanship has really improved?"

The alternating swordsmanship perceptions and cultivation images in his mind made Du Mu realize that although it was unbelievable, his swordsmanship had indeed advanced to a higher level.

This undoubtedly surprised and delighted him!

"Wait! Since swordsmanship can be improved, can Bailuo's breathing method also be improved?"

Martial arts, swordsmanship, knife skills, and even spearmanship and other martial arts specialties are all divided into hierarchical realms, entry, control, mastery, and even higher levels, but like Bailuo breathing method, Du Mu has never heard of a hierarchy.

After all, it is only the foundation of the foundation refining method, at most there is only the distinction between the beginner and the beginner, people with a little condition, after practicing the Bailuo Breathing Method for a year or two, after laying a good foundation, they will immediately switch to the intermediate level of the body refining method, and I have never heard of anyone advancing the Bailuo Breathing Method to a higher level.

With a hint of doubt and expectation, Du Mu slowly moved the mouse, clicked on the Xia Bailuo breathing method, and saw a line of text pop up out of thin air.

'Bailuo Breathing Method (Starter), which can be upgraded, consumes 5 Nightmare Energy. ’

'Do you want to upgrade?'

You can!

Surprise flashed in Du Mu's eyes, and he directly confirmed 'yes', and as the words gradually changed to 'Bailuo Breathing Method (Control)', there were many unfamiliar text images in his mind in an instant.

"Is this the mastery-level Bailuo breathing method?"

Forced to endure ecstasy, Du Mu hurriedly browsed the information in his mind.

Compared with the entry-level Bailuo Breathing Method, the level-up Bailuo Breathing Method not only discarded a lot of redundant breathing movements, but also had many minor adjustments.

"Give it a try?"

As soon as this thought came out, the curiosity and excitement in Du Mu's heart could no longer be suppressed, he couldn't wait to come to the center of the bedroom, regardless of the cold floor, sat cross-legged, closed his eyes and began to cultivate according to the upgraded Bailuo Breathing Method mantra.

As he settled in, the bedroom fell silent, except for the sound of a slight, regular breathing.

If you look closely, you can see that Du Mu's chest is slowly rising and falling in a rhythm that is very different from the previous cultivation, and as time passes, a vague air flow appears from between his nose and slowly floats.

"Whew~"

I don't know how long it took, Du Mu woke up from his cultivation, was stunned for a few seconds, and just wanted to get up, as soon as he moved, his body trembled violently, followed by a continuous crackling sound in his body, which lasted for five or six seconds before stopping.

"This feeling ......"

The sudden sound startled Du Mu, and when he came back to his senses, he immediately noticed that his body had undergone obvious changes.

Compared with before, his body was obviously a few points lighter, and there was a vigorous sense of strength surging up and down his body, and he clenched his fists, and he could clearly feel that his strength had increased a lot.

"It's true! Bailuo's breathing method has really improved!"

Du Mu looked excited, got up and kept pacing back and forth in the bedroom.

The effect of the mastery-level Bailuo breathing method is really amazing, the first cultivation has made his body significantly improved, and if he changes to the previous entry-level Bailuo breathing method, I am afraid that ten days and half a month of cultivation may not have the same effect.

"This computer is amazing!"

"By the way, isn't there still nightmare energy left?" Du Mu suddenly slapped his forehead, turned around and walked quickly to the computer, and at a glance, there were still 5 points of nightmare energy left.

Originally, there were a total of 11 nightmare energy, and it took 1 and 5 points to upgrade the sword technique and the Bailuo breathing method respectively, but now there are exactly 5 points left.

Du Mu clicked on the Bailuo breathing method again.

'Bailuo Breathing Method (Control), which can be upgraded, consumes 20 Nightmare Energy. ’

"20 o'clock!?"

Du Mu gasped, the Bailuo breathing method only required 5 nightmare energy from the entry level to the control level, and now it takes an astonishing 20 points to upgrade again, which is 4 times as much as before.

"It seems that there will be no upgrade for a while. Du Mu sighed regretfully.

The effect of the mastery-level Bailuo Breathing Method alone is so amazing, so how strong is the higher-level Bailuo Breathing Method?

If you can get it, you can greatly improve your physical fitness within three months, and you can't do it if you reach the standard of martial arts apprentices, but it's a pity that the nightmare energy is now only 5 points, which is far from meeting the needs of the upgrade, so you can only give up with regret.

"Fortunately, swordsmanship can still be improved!"

'Swordsmanship (Starter), upgradeable, costs 5 Nightmare Energy. ’

"5 Nightmare Energy is just right!"

The look of joy on Du Mu's face flashed, and he just wanted to click to upgrade, when he suddenly felt a trance, and the computer screen in front of him became blurry in an instant.

It was clear to him.

"I'm going to wake up. ”

......

The early morning sunlight slanted in from the window, making people feel warm and slightly dazzling at the same time, Du Mu raised his hand to block in front of him, and it took him a long time to get used to it, put down his palm, and looked at the ceiling motionlessly.

After a moment, he sat up suddenly, and quickly recalled the memories of swordsmanship and Bailuo breathing in his mind, and found that they were vivid and clear, engraved in the depths of his mind like a steel seal, and then he breathed a sigh of relief, followed by a full of ecstasy.

"It's not a dream!

"Wait, it's like a dream...... No matter, anyway, it's good that the swordsmanship and Bailuo breathing method have indeed been upgraded!"

The corners of Du Mu's mouth opened, and he sat on the bed stupidly.

He really didn't expect that the dream that had plagued him for a long time would become a huge surprise in the blink of an eye, with the existence of nightmare energy, his strength was bound to improve rapidly in the future, and the dream of being admitted to Wuke University did not seem to be so far away.

"Moreover, I am not tired at all today!" Du Mu moved his body and was surprised to find that the whole person was full of energy.

In the past, every time he woke up from a dream, his body was weak, he couldn't lift his energy, as if he had been exercising vigorously for several hours, and he had to lie down for a while to relieve his strength, which was as energetic as he is now.

Jumping out of bed, Du Mu raised his palm, recalled the memories in his mind, and slowly took a sword posture.

"Well, the swordsmanship perception has indeed increased, but the specific changes have to be known through actual practice. ”

As a poor boy, Du Mu can only eat three meals a day, so he naturally has no extra money to buy a sword for practice, and the only opportunity to contact the sword on weekdays is only when he takes martial arts classes in school, and there is no suitable sword tool to verify the changes in swordsmanship.

"But you can test it out in a martial arts class later!"

After glancing at the alarm clock and finding that it was time to leave home for school, Du Mu calmed down his excitement, quickly washed up and finished breakfast, then grabbed his schoolbag and rushed to school.
