"Seven days of calling?"

Du Mu's eyes showed a look of surprise and curiosity.

At first glance, the name looks a bit like a breathing technique, but since it is classified as a physical technique, it undoubtedly means that it is a physical technique rather than a physical exercise.

Confused, Du Mu casually clicked on the information.

'Seven Heavens Call, Strengthen Physical Skills, from Naruto Violet, unlock conditions: Constitution C, Physical Technique (Master), 100 Nightmare Energy'

His eyes fell on the words 'Enhanced Physical Skills', Du Mu couldn't help but be slightly surprised, this physical skill can't be the same as the Extreme Breaking Blade, a skill that can temporarily improve physical fitness, right?

After thinking for a few seconds, he directly chose to unlock.

More than ten seconds later, Du Mu, who had absorbed and digested the information in his mind, flashed with surprise and ecstasy.

The so-called 'Seven Heavenly Breaths' is indeed a martial art that greatly strengthens the physical fitness in a short period of time, and the practitioner activates the whole body by absorbing a large amount of oxygen, increasing lung capacity, thereby greatly improving agility and strength.

This physical technique is divided into three levels, the first activity, the second activity, and the third activity.

Du Mu could only perform the first activation of the Seven Days Breath Method at the moment, and even so, according to the information in his mind, his strength and agility could at least double as much.

Although it only increases his strength and agility, it is already a very strong increase, and it is no problem to increase his combat power by three to four thousand.

And as his physical fitness improves, the effect of this physical skill will only get stronger and stronger.

"The strength and agility of the skill in the first active state are nearly doubled, so how many times can the second and third active increases the strength, two, three times?"

Even with Du Mu's calmness, his breathing couldn't help but be a little heavier at this time.

It took him a long time to calm down the emotions stirring in his heart and return his attention to the personal panel.

After unlocking and upgrading, Du Mu's combat power soared by nearly 800 again, reaching 6026, and his combat power rating also came to B-level.

10,000 combat power is the dividing line between seven stars and eight stars, and when converted, the combat power of more than 6,000 is equivalent to the seven-star beginner level, and it is only one step away from stepping into the seven-star intermediate level.

However, this is only Du Mu's strength in his normal state, if you count many hole cards, his strength will skyrocket by another level.

Thinking of this, Du Mu took out the Darkness Chaser, held it in his hand and closed his eyes to carefully feel the improvement of his body's strength.

"Strange....... This power amplification ......"

After a moment, he opened his eyes in surprise and stared at the blue and silver blade of the Darkchaser, and then, as if thinking of something, he immediately looked up at the personal panel.

'Power: C+'

'Agile: C+'

"Strength and agility have only increased by one level?" Du Mu's eyes widened slightly, it is true that the Darkness Chaser's increase in agility is only one level, but the strength increase should be three levels.

After thinking for a while, he suddenly came to his senses and sighed regretfully.

"Sure enough, there's an upper limit to the increase of the Darkchaser!"

Du Mu had vaguely guessed about this before, after all, the Darkness Chaser was not the best weapon in the exchange list of dream weapons, and the exchange price was only 300 nightmare energy, and the number of weapons worth thousands of nightmare energy on the list was more than a single digit.

If the Darkness Chaser could increase his strength and agility indefinitely, it would be worth more than 300 Nightmare Energy.

"Looks like we're going to change weapons, but it's ......"

Du Mu glanced at the nightmare energy column on the panel with only 148 points left, and shook his head again.

He then activated the probe and found that his combat power had increased to 7101, an increase of about 1000.

"Try the Seven Days Breathing Method. ”

Taking a deep breath, Du Mu's body sank suddenly, and in the next moment, the terrifying momentum suddenly erupted on itself, and the invisible energy spread in all directions with him as the center, setting off a hurricane in the calm bedroom.

In the field of vision, the number representing combat power skyrocketed wildly, breaking through 8,000, 9,000, and 10,000 in an instant, and it didn't stop until 10,735.

Eight-star beginner!

Pastor Du let out a sigh, feeling the powerful power surging up and down his body, and the ecstasy on his face flashed.

"More than 3,600 combat power increases...... This skill is really strong!"

Strongly excited, Du Mu groaned secretly.

Although he didn't know the specific combat strength of the nine-star martial artist, there was no way to divide the combat power boundaries of each level of the eight-star realm, but with his current strength, coupled with the increase brought by the black sword-breaking blade, as well as the breath of Gray Dream and all things, he should have surpassed the eight-star intermediate level, as for the eight-star high-level and eight-star peak, and even higher, he had to actually fight to know.

Lifting the seven-day call, the momentum on Du Mu's body returned to its original mediocre state in a blink of an eye.

"Next, we have to find a way to save more nightmare energy and get a good weapon as soon as possible. ”

Standing in front of the desk and pondering for a moment, Du Mu closed the computer screen, left the apartment and walked out into the street, and then took out a metal card from the dimensional house.

But it's the card from the Destiny Arena with a halo painted on the front!

The moment the card appeared in Du Mu's palm, it suddenly shone brightly, like a firework, and suddenly shattered into countless purple, blue, and blue light particles.

The light particles slowly fell, leaving countless bright light tracks in the void, and the light tracks were intertwined with each other, gradually condensing into Du Mu's familiar halo.

Du Mu watched this scene the whole time, and his face was not surprised, as early as when he got the card, he guessed the role of the latter.

After the halo was condensed, the light above gradually faded until it disappeared, and the entire surface became a pool of stagnant water.

Seeing this scene, Du Mu felt regret and joy in his heart.

The situation in front of him undoubtedly meant that on the other side of the halo was a world in the process of transformation, which usually had a large number of nightmare creatures, which was in line with his current desperate need for nightmare energy.

However, on the other hand, it also means that there are no gacha machines there, so naturally there is no possibility of obtaining new items.

There were gains and losses, Du Mu quickly adjusted his mentality, clenched the dark chaser in his hand, jumped into the halo.

There was a sticky feeling like a quagmire all around.

Du Mu opened his eyes, and everything he saw was gloomy, but fortunately, it was the second time he had entered the same halo, and he quickly got used to it, and with a little calm, he swam towards the white light ball the size of a basketball in the distance.

I don't know how long it took, as a strong suction force came, Du Mu's body tightened and loosened, and his eyes suddenly opened up.

When he came back to his senses, he found that he had stepped on a brownish-yellow earth.

Standing and looking, the blue sky and white clouds, the occasional birds flying by in the sky, the ears occasionally heard the crisp birdsong, the humid breeze blows head-on, and the sparkling sea instantly jumps into view.

Du Mu retracted his gaze and looked around with a little surprise.

“...... It's an island!"
