That mysterious feeling rippled in Mu Chen's heart, so that his face also had a look of surprise that was difficult to contain.

This kind of feeling had also appeared when the Great Floating Tu Jue had broken through to the condensation level before, originally Mu Chen thought that the next time he appeared, it would at least be possible after he reached the Melting Heaven Realm, but he didn't expect it to come so early.

"Is it because of the power of the heavenly thunder here?"

Mu Chen thought about it, the heavenly thunder here has a pretty good effect on refining spiritual power, and after a few days of cultivation, Mu Chen can feel the subtle changes in the spiritual power in his body.

It was a more condensed feeling.

Mu Chen suppressed the surprise in his heart, this mysterious feeling was a sign before the breakthrough of the Great Floating Tu Jue, but it was not a real breakthrough, next, he had to grasp this mysterious feeling, and then make a real breakthrough.

His current Great Floating Technique has reached the level of condensation, and if he takes a step further, that is, the level of the Transformation Tower, as long as he reaches this step, his Great Floating Slaughter Recipe can be regarded as a real entry into the house!

Mu Chen has great curiosity about this mysterious spiritual recipe left to him by his mother herself, according to Mu Feng, the mysterious spiritual vein in his body was sealed by his mother, and if you want to unlock this seal, this big floating recipe is the key.

Therefore, the fact that the Great Floating Tu Technique can make a breakthrough is almost more important in Mu Chen's opinion than his breakthrough to the late stage of the Divine Spirit Realm.

Mu Chen sat on the detonator, and urged the detonator again, and suddenly the dark golden light flickered, and the layers of dark clouds that had been a little sign of stopping rolled wildly again, and then continued to shoot down from the dark clouds, splitting on Mu Chen's body.

Snort.

The bright thunder light spread and beat on the surface of Mu Chen's body, and he was running the Great Floating Tu Jue with all his might, urging the dark spiritual power, surging rapidly in the meridians.

And when Mu Chen urged the Great Floating Tu Technique with all his might, he could also perceive the depths of his body. There seem to be mysterious black points of light, slowly emerging...

However, those mysterious points of light were only faintly visible, and only when the thunder struck Mu Chen's body would they be slightly brighter.

"Sure enough, it's because of the power of the thunder. ”

Mu Chen noticed this scene. also understood, and then he suddenly opened his eyes, stood up, and looked deeper: "The efficiency of this third-layer heavenly thunder is too slow, go on like this." I'm afraid that the subtle feeling will gradually fade, and I will lose the opportunity to break through this Great Floating Slaughter Technique. ”

Most of this kind of breakthrough is because of the opportunity, once you miss it, you can only wait for the next time.

Mu Chen's eyes flashed, and he immediately swept out directly, his body moved, and he pushed his speed to the extreme, and went straight to the depths of this third-layer thunder domain.

In less than ten minutes, Mu Chen appeared in the deepest part of the third layer. The space there was distorted again, and outside the distorted space, there was a faint light curtain.

If you want to enter the fourth layer of the Thunder Domain, you need the strength of the Melting Heaven Realm, and this kind of light curtain will isolate the students under this realm.

"Huh!"

Mu Chen directly ignored the light curtain and swept straight out towards it.

At this time, there are also many figures around here, and almost all of them have the strength of the Melting Heaven Realm. Obviously, he is also excellent in the North Cangling Academy, and when they saw Mu Chen's figure, they were stunned, where did this kid come from. Don't you know that this fourth layer is only qualified to enter if you have reached the strength of the Melting Heaven Realm?

Some people grinned and grinned, a bit of a lively mentality, they knew how powerful this light curtain was, even if it didn't hurt these forcible students, but it was definitely a bit embarrassing.

For those eyes around him, Mu Chen didn't pay attention to it. When he was about to touch the light curtain, his five fingers suddenly clenched, and with a low shout, a punch burst out.

Four black light seals suddenly emerged from Mu Chen's fist, and then accompanied by the fist wind, they turned into black light and slammed into the light curtain.

Airplanes!

A circle of ripples rippled from under Mu Chen's fist, and then became more and more intense, and in the next moment, only a small sound was heard, and the light curtain in front of Mu Chen was actually torn out by him.

Swish!

As soon as the crack appeared, Mu Chen quickly drilled into it, leaving a lot of stunned eyes around him, when did this fourth layer even people from the late stage of the Divine Spirit Realm be able to enter?

"Where did this guy come from? With the strength of the late stage of the Divine Spirit Realm, he can perform an attack comparable to the strength of the early stage of the Melting Heaven Realm, this guy has some ability. ”

Everyone was stunned for a while, but soon someone reacted, and immediately exclaimed, and also used his body to rush into the fourth layer of the thunder domain.

And when they rushed into the fourth layer of the thunder domain, Mu Chen's figure had disappeared, and he quickly shuttled through this fourth layer, and as he entered here, he could clearly feel the difference between this fourth layer and the third layer.

The dark clouds in the sky have turned into a pitch black color, although the frequency of thunder flickering is not as high as that of the third layer, but the occasional low thunder sound lets people know how powerful the thunder here is.

Mu Chen rushed into the fourth floor, then found a mine-guiding platform that was unoccupied, quickly fell, sat down, and immediately urged the mine-guiding platform.

Rumble!

As soon as Mu Chen urged the thunder channel, the black cloud above his head was churning, looking like a terrifying giant face, revealing hideousness, and then with a bang, a heavenly thunder of nearly several zhang in size rushed down like a beam of light, and the next moment, it was already fiercely impacted on Mu Chen's body.

That kind of strong impact made Mu Chen's body tremble violently, and a sharp pain came from the surface of his body, he could feel that this fourth-layer heavenly thunder was more than one grade stronger than the third-layer, no wonder only the students of the Melting Heaven Realm were allowed to enter here.

The thunder light flickered on the surface of Mu Chen's body, and then he sensed a rather powerful heavenly thunder power pouring into his body, this was just the power of the heavenly thunder contained in a heavenly thunder, almost comparable to the ten heavenly thunders of the third layer!

"Not bad. ”

Mu Chen's heart was extremely satisfied, and his mind began to sink into his body, and with the large amount of heavenly thunder power pouring into his body, he could feel that inside his body, the mysterious black points of light that loomed began to brighten at a slow speed.

Of course, this speed is slow, but compared to before. It's more than ten times faster.

Mu Chen condensed his mind, and after gradually adapting to the fourth layer of heavenly thunder, he also began to urge the thunder platform to speed up the frequency of the heavenly thunder falling, and it was too late. The black clouds above the sky were also becoming more and more violent, and the thunder continued to fall, and that kind of violent scene, even some of the students of the Heaven Melting Realm in the distance were a little shocked when they saw it.

To be able to trigger a thunder bombardment of this frequency so unscrupulously in this fourth layer. Ordinary Heaven Fusion Realm early stage students simply did not possess this kind of courage and ability.

Mu Chen still ignored some of the surprised glances he aroused, he completely sank his mind into his body, constantly running the Great Floating Tu Technique, and feeling that mysterious feeling.

The thunder kept falling, Mu Chen seemed to shield the outside world, just paying attention to the body, and under this kind of selfless cultivation, ten days will soon be in the past.

In these ten days. Mu Chen's body was almost immobile, and the thunder in the black clouds fell overwhelmingly without stopping at all, which became an extremely eye-catching scene in this area.

Many of the surrounding cultivators were looking at it with a little horror, and on the dark gold thunder platform, the thunder light was raging wildly, and a slender figure could be vaguely seen sitting cross-legged.

In this fourth layer, they would rarely see a scene like this one in front of them, for a full ten days. Causing heavenly thunder without interruption, this kind of thing, I'm afraid that even those who have stepped into the middle stage of the Rongtian Realm will be a little unbearable, right?

Who the hell is this guy?

Not far from this area, there is a mine-channeling platform. There were also several figures standing, and they were also a little surprised to look at the scene of thunder and thunder in the distance.

In front of these people, there was a rather familiar face, the girl in a flaming red dress and a cold face, who lost to Mu Chen's An Ran in the Northern Cang Realm.

"This guy is amazing. This level of heavenly thunder, even I can't bear it, I really want to see where the cow man came out..."Beside An Ran, a young man smiled, his face with unconcealed surprise.

"There are so many students in our North Cangling Academy, I don't know how many people are hiding dragons and crouching tigers, many people are secretly cultivating, waiting for the day when they will become a blockbuster, maybe this guy is also in this column. Another young man laughed.

An Ran listened to their words, and Meimu also stared at the thunderous place, where a figure loomed, and that figure gave her a somewhat familiar feeling.

"Who the hell is it?" An Ran frowned and muttered to himself.

"Hey, the thunder there's starting to wane. Suddenly, the young man beside An Ran exclaimed.

An Ran looked at it, and sure enough, he saw that the originally violent thunder there began to weaken, and the movement here was extremely eye-catching these days, so at the same time, other places also projected surprised and curious eyes.

And when the countless eyes gathered, Mu Chen, who was sitting in the thunder light, was nervously concerned about his body, and in the depths of his body, the mysterious black point of light that was originally looming had become quite bright at this time, and a strange fluctuation quietly rippled out.

Buzzing.

Suddenly, Mu Chen felt those mysterious black points of light vibrate, and then he saw that the black points of light actually extended out black rays at this time.

These rays of light will come out, and they seem to link up all the black points of light.

Mu Chen looked at this scene, and his heart was also raised.

After half an hour, the black light finally completed the link completely, and at the moment when the link was formed, Mu Chen's heart jumped violently, because he saw that when those black light spots were linked by the light, the light emitted, and a mysterious black tower slowly took shape in his body.

And in the moment when the mysterious black tower was formed, there seemed to be an ancient voice that seemed to have traveled through time and space, with obscurity and mystery, slowly echoing in his body.

"Incarnate the Futu Tower, I will take charge of Xuanhuang. ”
