It's not so easy to see and get close.

For example, we can see the vast starry sky, but it is very difficult to get close to any planet we see.

Right now, although Long Fei saw the star core of the Demon Domain's Eight Heavenly Planets, when he really accelerated forward and wanted to get closer to the star core, he was surprised to find that the star core seemed to be very far away from him.

What made him feel the most incredible was that when he entered the vacuum area created by the glorious power released by the star core, he found that the oppressive force that existed in it was far stronger than the outside world, if it weren't for his defense, which was perverted enough to easily withstand the full force of the 9th level cultivator of the Qiankun Realm, I am afraid that at this moment, he has been torn to pieces by the crushing force of the vacuum area.

"I really didn't expect that the power released by the core of this planet is so strong and perverted, if I refine it, on this planet, I should be able to use its power to sweep any Demon Domain master. ”

Long Fei, who was in the vacuum area, resisted hard with his own strong defense, and in the process of his advancement, he learned the experience value of the exercises through the voice prompts of the system, which was changing rapidly, and the changes in these data were only a little slower when he used secret techniques and gathered immortal divine power to assist in cultivation.

It seemed to be a very close distance, Long Fei was in that vacuum area, walking through for nearly half a month, and the exercises he used to resist the oppressive force were also raised by one level, reaching the level of 8, and only then did he get close to the star core as he wished, and reached the edge of the star core of this huge planet.

Then, without the slightest hesitation, Long Fei immediately tried to cast a secret technique, guiding the power of system refining, turning into thousands of tentacles like spikes and spears, extending out and stabbing at the natural protective layer of the star core in front of him.

With a series of "poof" sounds, the powerful defense layer was pierced by the power released by Long Fei, making the refining power of the system easily contact the main body of the star core, and then the strong refining power of the system began to run rapidly.

The refining power of the system is extremely terrifying, even if it is the pinnacle existence in this world, it is not as good as just in case.

Therefore, the star core of this planet was very fragile in front of the refining power urged by Long Fei, and it only took a week for this star core containing terrifying energy to be refined by Long Fei with the power of the system.

The refining of the star core was successful, and Long Fei probed and recognized the lighting of the gray planet on the "Ten Thousand Star Array Map" in the sea, and learned that after refining this planet, he actually directly lit up all the gray planets on the outer edge of the "Ten Thousand Star Array Map".

This means that after refining this planet, he has gained far more than he expected.

However, Long Fei knew very well in his heart that the closer he got to the gray planet on the several rings in the center of the array, if he wanted to light it up, would it definitely be much more than now.

Therefore, Long Fei estimated that if he wanted to completely light up all the gray nodes on the "Ten Thousand Star Array Diagram", he would have to refine at least more than ten huge planets like this moment before he could get his wish.

"The star core has been completely refined, and the resistance of my flesh and blood body is strong enough to withstand the impact of a large amount of star core power gathered in my body, and at the moment, with the power of this planet's star core, it should be enough to sweep through the demon domain and come to any creature on this planet. ”

After Long Fei checked the data on the personal attribute panel, he did not continue to stay in the depths of this planet, so he left as fast as possible, returned along the same path, and rushed to the space where the core formation at the bottom of the Heavenly Demon Domain Demon Cultivation Pool was located.

Because Long Fei refined the star core of this planet, all the obstacles in the underground space disappeared, and Long Fei hurried up, as easily as flying through the air, which made Long Fei only take nearly a day to successfully reach the edge of the space where the core formation of the Heavenly Demon Domain's Demon Cultivation Pool was located.

Long Fei's appearance this time was not as sneaky as last time, but directly and openly disguised his identity, broke through the hard soil layer that blocked the core formation, and reached the core formation area.

The Demon Domain masters who were holding on to the center of the core formation hub quickly noticed Long Fei's appearance, and they immediately stopped practicing and quickly formed an encirclement against Long Fei who suddenly appeared.

After besieging him, the master who was the strongest, cultivated to the highest realm, and already possessed the human image of a perfect form, stared at Long Fei with cold eyes and looked up and down for a while, and then shouted at him: "Who are you?

"You so many masters are lurking here, you should be waiting for me to appear, right?" Long Fei replied casually.

"Are you that abominable human monk?" The master, hearing Long Fei's words, was shocked for a moment.

"In the eyes of your adversaries, I am indeed hateful, but in the eyes of us humans, I am a great hero who dares to confront the adversary in a real head-to-head battle. Long Fei replied with a smile.

"Big hero? Huh...... I don't know what life or death, today I will tell you what a tragic fate will happen to those who dare to provoke the majesty of my Demon Domain. The master snorted coldly, and then said no more, and directly waved his hand to all the masters who were in the joint attack formation, and issued an order to attack Long Fei.

Whoosh ......

As the master's attack order was issued, the surrounding masters cast spells one after another, casting their best killing methods, releasing powerful magic power, turning into a magic blade with amazing lethality, forming a killing array, slashing through the void, and slashing towards Long Fei.

"With this level of strength, I'm embarrassed to show it in front of me. ”

Long Fei smiled coldly, and then swung his fist at great speed, meeting the approaching demon blade with lightning speed.

Bang bang bang......

A series of crashing sounds rang out.

Every time Long Fei punched down, a demonic blade collapsed and turned into demonic qi.

None of the magic blades close to Long Fei were able to break through the defense of his fists and hit his body.

Seeing the scene in their sight, all the demons at the scene were stunned, because they never dreamed that this human monk who suddenly appeared and disguised as a demon would be so strong in combat power that he could calmly deal with the joint siege of all their masters.

In fact, the attack power on Long Fei's fist was not enough to easily defeat the demon blade attacks released by all the demon domain masters, if he didn't refine the star core power of this planet, and couldn't secretly accumulate a little star core power into the fist strength, any magic blade would be enough to make him feel frightened, thus directly delaying the pace of his next attack.

In this way, the scene that everyone will see will be that he has been hit by a large number of magic blades.
