Early the next morning, Du Mu called Shi Yuanliang and asked him to help ask for leave from the school, on the grounds that he had used too much cultivation and was a little uncomfortable.

Later, he pretended to go out to buy something, and halfway through he touched the headquarters of the Silver Ring Gang to take a look, and found that there were already many police cars parked there, and several policemen were hurriedly arranging a yellow cordon around them.

Du Mu blended into the crowd and inquired to learn that someone heard the gunfire last night and called the police, but it was not until this morning that the police arrived late and blocked the area around the factory.

"Is the work efficiency really too low? Or do you realize that it's a gangster vendetta and don't want to pay attention to it, and plan to come back and clean up the mess after the fight is over?"

Looking at the lazy looking and casual policemen in the yellow line, Du Mu gradually relaxed his heart.

"Either way, it's good for me, at least the chances of finding me are extremely low!"

With a judgment in his heart, Du Mu stopped staying, turned around and left the scene, planning to go home to cultivate.

Although the main purpose of taking leave is to recuperate from injuries, but cultivation cannot be left behind, Du Mu intends to strive to break through his strength to E-level before the wound heals, and at that time his strength will inevitably usher in another wave of growth.

......

Time flies by in cultivation.

Ten days have passed in a blink of an eye, and the injury on Du Mu's chest has basically healed, and I don't know if it is because his physique has become stronger, and he has not even left a scar.

These days, in addition to cultivating the Bailuo Breathing Method, he has put most of his energy into familiarizing himself with sword skills and physical skills, and his skill proficiency has increased rapidly, especially the iron block.

As a powerful physical skill that once saved his life, Du Mu spent a lot of time studying the iron block, and after ten days, he can now achieve a movement of his mind, and his body can instantly enter the state of the iron block, which is enough to be used in actual combat.

Unfortunately, the iron block only lasts for just over 2 seconds and less than 3 seconds, and once it encounters an overly powerful attack, the iron block will be broken, and it will be injured, just like when it was hit by a pistol before.

On the other hand, ten days of cultivation finally allowed Du Mu's strength to successfully break through to E-level, and so far, all his attributes have reached E-level or above, and his perception has reached E-level or above.

The breakthrough of attributes, the result is that the upgrade conditions of skills are met.

'Bailuo breathing method, which can be upgraded, consumes 20 nightmare energy, strength E-, constitution E-, agility E-. ’

'Do you want to upgrade?'

In the dream bedroom, Du Mu frowned slightly, stared at the computer screen for a long time, and sighed slightly.

"It's a pity, only the upgrade conditions of the Bailuo Breathing Method are up to standard, and the swordsmanship and physical skills still can't be upgraded. ”

"You don't have to have an E or even an E+ level to meet the conditions, right?"

Shaking his head, Du Mu finally chose to upgrade the Bailuo Breathing Method.

"Forget it, it's not bad to be able to upgrade the Bailuo Breathing Method, at least the speed of physical fitness enhancement will be faster in the future!"

As soon as the thought moved, Du Mu saw the nightmare energy column on the screen, the original value of '26' fell rapidly, and instantly fell to '6', and in the next second, a majestic massive number of pictures and texts appeared out of thin air, squeezing into his mind.

With a bang, Du Mu felt as if a thunderbolt had been thrown into his mind, and countless pieces of information were tumbling and surging, so that his head was almost blown up, and the whole person involuntarily covered his head and squatted down.

The unbearable pain lasted for half a minute before it quickly faded like a tide.

"Ho...... Ho...... How is it so much more painful this time than before?"

Du Mu sweated profusely and got up from the ground, took out a bottle of Nutrition Express and took a sip, resting for five or six minutes before he recovered and looked at the personal information on the computer screen again.

Clicking on each skill and unlock interface in turn, Du Mu found that Gangliluo and Iron Block were still in a state where they could not be upgraded, and there were no new skills on the unlocking interface.

Sighing lightly, Du Mu turned off the computer and began to concentrate on sorting out the new information in his mind.

After being promoted to the mastery level, the Bailuo Breathing Method once again deleted a lot of breathing movements, and the entire breathing process became more and more streamlined, but the process of refining energy to replenish the flesh was greatly strengthened.

As we all know, the process of strengthening physical fitness through basic breathing is actually the process of accelerating gastrointestinal peristalsis to digest food into energy through a specific breathing rhythm, and then encourage muscles to absorb it, thereby strengthening the body.

The most critical part of the whole process lies in the amount of converted energy, conversion efficiency and absorption efficiency, the latter two of which depend on the type of breathing method and personal qualifications, and it is not easy to improve.

In contrast, it is much easier for the former to change, it is nothing more than the quality of the food, for example, the energy after the transformation of precious medicinal materials must be far more than ordinary food.

The better the quality of the food, the more energy converted, and the faster the physical fitness will naturally grow, which is why it is easier for children from rich families to improve their physical fitness than children from poor families.

After the upgrade, the main enhancement of the Bailuo Breathing Method is the energy conversion efficiency and absorption efficiency, the digestion of food into energy during the cultivation process, and the proportion and speed of the body's absorption of energy have been greatly improved.

"Try it and see how it goes. ”

Taking out an unopened bottle of Nutrition Express from the dimensional room, Du Mu raised his head and drank it all in one gulp, then returned to the bed and sat cross-legged, closed his eyes and waited for a while, his chest began to gradually rise and fall in some mysterious rhythm.

If you take a closer look, you can find that Du Mu's abdomen is squirming at a very fast frequency, and there is even a faint roar like thunder in his body, but the sound is very slight, and it is easy to ignore it if he doesn't listen carefully.

The strange scene lasted for almost 10 minutes before Du Mu's undulating chest and abdomen slowly subsided, and he opened his eyes suddenly, and there was an indescribable joy in his eyes.

"It's amazing, it's at least three times as efficient!"

In the past, Du Mu drank a bottle of Nutrition Express, and it was almost consumed after half an hour of cultivation, but now he only lasted for ten minutes, and there was an unbearable feeling of hunger in his stomach, and he was forced to withdraw from the cultivation state.

"The effect of the mastery-level Bailuo breathing method is actually so strong!"

For a while, Du Mu was surprised and distressed.

It is certainly a good thing that the cultivation speed will be faster, but it also means that the cultivation consumption will also increase to three times the original amount.

The gacha draw rate of the Nutrition Express is not high, and it was only barely able to keep up with the cultivation consumption before, but now it is far from enough to change to the upgraded Bailuo Breathing Method.

"It looks like I'm going to have to buy more meat or herbs next. Du Mu muttered, the importance of strengthening physical fitness is undoubtedly in the first place, no matter what, you can't let food hold back your cultivation.

"Fortunately, I got a lot of money from the Silver Ring Gang on my previous trip, otherwise I would have to eat dirt. ”

There is still a large amount of cash and a safe from the Silverring Gang lying in the dimensional house, so there is no need to worry about running out of money for the time being.

Sighing, Du Mu clicked on the Bailuo Breathing Method again, and found that the nightmare energy required for the next upgrade had actually increased to a full 80 points.

He suddenly took a deep breath, 80 nightmare energy, when will this be gathered?

"And there are hidden conditions such as physical fitness, it seems that there will be no need to think about upgrading the breathing method for a while!"

Shrugging his shoulders, Du Mu didn't care, the proficient-level Bailuo Breathing Method was enough for the time being, and no matter how strong it was, maybe he wouldn't be able to support the consumption required for cultivation, but it would not be beautiful.

"Let's cultivate. ”
