It's just that the martial artists of the Mortal Realm are not qualified to set foot on the Starry Sky Ancient Road. If you insist on going, you are allowed, but survival here is a big problem.

The warriors here are not very harmonious, and in the Apocalypse City, there will be constant disputes and fights, and no one will care.

Some people looked here with unkind eyes, but when they saw Sikong Changyue in the Sky Realm, some people silently withdrew their gaze.

Under the gaze of others, Li Mu and the others couldn't help but feel the crisis.

"Break through with peace of mind! I'll guard the pass for you!" Glancing at a few people, Sikong Changyue said lightly.

"Thank you, sir!"

Everyone clenched their fists gratefully, and then sat down cross-legged on the ground.

Sikong Changyue sent them here, the task is equivalent to being completed, and being able to guard the customs for them is a human favor, after all, the latter has protected them for twenty years, maybe he can't bear to let them encounter danger, so he offered to help a few people guard the customs.

"Boom~~~"

Li Mu also closed his eyes, no longer suppressing his cultivation, the level of the Peep Heaven Realm, like a film, was easily poked open, in the realm of half a step Peeping into the Sky, they stayed too long, suppressed for a long time, once let go, the breakthrough was a matter of course.

Whew~~~

A large amount of spiritual energy is pouring from all directions, and the spiritual energy here is more intense and more refined, even if you don't use spirit stones, you can break through the realm, but it takes a long time.

Li Mu controlled the absorption of aura, while secretly absorbing the aura in the storage ring, the aura he needed was too majestic, but in this case, he didn't want to be exposed, so he could only rely on the spirit stone to break through.

Last time from the Evil Sword Alliance, he robbed too many spirit stones, and only used a small part when he broke through the ninth layer of metamorphosis, fortunately, there were those spirit stones, which could speed up the breakthrough, and at the same time, others would not be able to detect it.

"Buzz~~~"

In Li Mu's mind, earth-shaking changes took place, and the transparent divine soul was slowly rendered with a layer of gold, and the treasure was solemnly suspended in his mind.

Breaking through the Voyeur Heaven Realm, the biggest change for martial artists is the divine soul, and the souls of all martial artists will be golden and become more condensed.

Such a divine soul already has the ability to break away from the physical body, even if the physical body dies, as long as the divine soul is not destroyed, it can also walk between heaven and earth.

It's just that the combat power will be greatly reduced, and the soul itself will be easier to destroy.

With the increase of the realm, Li Mu's physical body has also changed, almost doubling compared to the original.

The most amazing thing is the change in the dantian, after the martial artist breaks through the mortal realm, the aura in the dantian and the essence of the body have begun to merge, and a ball of flesh similar to a life body will be produced in the dantian.

After entering the realm of metamorphosis, the meat ball grew hands, feet and facial features, and became a villain with the same appearance as Li Mu. This villain has Li Mu's aura, which is a condensation of his aura.

Martial artists cultivate things, essence, qi, and spirit. Among them, the essence represents the physical body, which is the root of a warrior. Qi is the aura, the aura grows out of the body, has been substantiated, is the martial artist's cultivation of the Tao fruit, can be called the spirit body, with it, you can communicate the power of heaven and earth, use the rules of heaven and earth to attack, this is why this realm is named the realm of peeping into the sky.

The so-called god is the soul of the gods, and after peeking into the heavenly realm, the three must be cultivated together, and none of them is indispensable.

There are three realms in total, primary, intermediate, and advanced.

When a martial artist breaks through the Voyeur Intermediate Level, the Divine Soul and Spirit Body will triple at the same time, reaching a size of three inches. Entering the advanced realm of peeping into the sky, the soul and spirit of the martial artist will grow to about a foot.

The physique of the martial artist is different, the cultivation method is different, and the power of the spirit body and the divine soul are naturally different·······

Three days passed slowly, Li Mu was the first to get up, and as soon as he stood up, he felt a huge crisis descending on the starry sky, it was a thunderstorm.

Martial artists who break through the rules of heaven will experience thunder tribulations, no one is an exception, of course Li Mu is the same, not to mention, when he broke through the mortal realm, he had already experienced several thunder tribulations.

"Lord Sikong!" Li Mu looked at Sikong Changyue, who understood his situation, and immediately nodded: "Go!"

"Hmm!"

Li Mu nodded, flew away from the city wall, and flew towards the depths of the starry sky, every step he took was a distance of 100,000 miles, and soon disappeared outside the perception of Sikong Changyue.

"This kid, is it necessary to be so cautious when crossing a thunder tribulation?" Sikong Changyue shook his head slightly, feeling that Li Mu was a little too cautious, martial artists who broke through the Heavenly Realm would survive the thunder tribulation, there was no need to run so far, as long as they didn't cross the tribulation in Apocalypse City.

What he didn't know was that Li Mu had already attracted the Thunder Tribulation when he broke through the Mortal Realm, but he was afraid that this Thunder Tribulation would be even more terrifying, in order not to attract people's eyes, it was better to be secretive.

Rumble~~~

In a starry sky with no people, the power of blue thunder and lightning poured down, like a waterfall, and under the terrifying power of thunder and lightning, small meteorites burst in the air.

The power of thunder and lightning this time was much more terrifying than Li Mu imagined, not only did the color of the thunder and lightning completely turn dark blue, but also every thunderbolt was dozens of times thicker than when he broke through the ninth layer of transformation.

Burst~~~

Li Mu coughed up blood, and the muscles in his body showed cracks, even with his current body, he couldn't bear it.

The thunder and lightning possessed incomparable destructive energy, and at the same time, it also had unimaginable life power, and his split body had all recovered before the second thunderbolt power came.

Thundered~~~

Click~~~

The second thunderbolt fell, and this thunderbolt was even more terrifying, a huge cylindrical thunderbolt with a diameter of nearly 100 meters.

This time, Li Mu was scorched on the outside and tender on the inside, his head was dizzy, and his perfectly streamlined body was bathed in thunder and lightning, and terrifying blood lines were all over his body, which were cracks.

This time the injury was even more severe, almost hurting the inner abdomen.

"Boom Boom~~~~"

Pillars of lightning fell from the sky, outlining a fascinating scene in the starry sky, and the entire starry sky was rendered a layer of dark blue.

There were a total of nine thunderstorms, each more terrifying than the other, and when the last thunderbolt fell, the diameter had reached a kilometer.

Burst~~~

Li Mu coughed up blood, his whole body was burnt black, the rich vitality power spread out from his body, his body recovered rapidly, and pieces of black charcoal-like substances fell from the surface, revealing the crystal white skin inside.

All the black charcoal fell, and all the injuries inside and outside the body were recovered at this moment.

Glancing at the fact that there was no one around, he quickly left and came to Apocalypse City again.

"The Thunder Tribulation is over!"

Glancing at Li Mu, Sikong Changyue couldn't help but be surprised, the current latter gave him a feeling like an abyss, and he couldn't see through Li Mu's body anymore.
