The cultivation of the exercises is related to the attributes of heaven and earth aura that cultivators can mobilize. Bayi?? Chinese??? .?8?1(8)Z?(a).?C(8)O(8)M?

It's as if Li Chen's previous cultivation was the Vermilion Bird Divine Technique as the main exercise, which is a fire-based exercise, so the aura he can mobilize the most is the fire-based aura.

It's not that other auras other than the fire aura can't be mobilized, it's just that it's much more difficult to mobilize, just like commanding a completely unfamiliar army, and the combat effectiveness it can play is completely different from commanding your own troops.

In addition, if you cultivate the fire system exercises, then your strength will be stronger in places where the natural fire aura is rich such as volcanoes and fire seas, and if you cultivate the water system aura, then your strength will also increase greatly in places where there is water.

This is that the exercises of cultivation are closely related to the spiritual aura of heaven and earth, and the aura of heaven and earth is closely related to the environment.

Generally speaking, before truly finding their own martial arts, a martial artist is majoring in one main attribute exercise. Just like Li Chen, he didn't only have fire attribute exercises, but he had always majored in the Vermilion Bird Divine Technique.

This is not to say that a person can only cultivate one attribute of the exercises, this is because the cultivation degree of focusing on one attribute of the exercises is faster, and they can also be more proficient in the martial arts of a certain line.

Distracting yourself from cultivating the exercises of other departments will naturally divide some of your energy.

Now the reason why Li Chen began to cultivate the Thunder System Technique was because after he cultivated in the Polar Pool, his Vermilion Bird Divine Technique had already cultivated to the fullest, reaching a bottleneck, and it was difficult to improve more for the time being.

In addition, he was extremely proficient in various fire-based martial arts three thousand years ago, and now he doesn't need to spend more time cultivating, so he can devote part of his energy to cultivating other exercises.

The most important thing is that he feels that cultivating the exercises of the thunder system can increase his strength, which is conducive to the upcoming battle with Yun Haotian.

At this time, Li Chen sat cross-legged on the bed, his eyes closed, and his heart was facing the sky.

Thunder City was originally filled with thunder aura everywhere, and people could feel a faint power of thunder when they breathed.

He lived in the highest inn in Thunder City, with a nine-story top floor, and here he felt close to the thunder in the sky, which could be said to be an excellent cultivation condition.

Today, he drank thunder tea and thunder wine and ate a lot of thunder food, and he had a deep understanding of the thunder aura, and it was best to start his first thunder system cultivation here.

He is now practicing a thunder system exercise called "Thunder Demon True Scripture", which is an extremely domineering exercise, it is said that the person who created this exercise was a big devil, calling himself the Thunder Demon Emperor, killing countless people, but he was strong, so no one had anything to do.

In the end, it was a Martial Emperor who made a move, and it was only then that he was killed, and it was rumored that this Martial Emperor was also injured because of this, and it took a long time to recover.

It can be seen that this Thunder Demon True Scripture should also be an extremely powerful exercise, which is one of the reasons why Li Chen chose it.

In addition, this Thunder Demon Sutra can also borrow thunder and lightning to quench the body, remove impurities from the body, greatly enhance the body, and is also infinitely useful.

At the beginning, the Thunder Demon Emperor used this Thunder Demon True Scripture to cultivate into the ultimate Thunder Demon Body, so that Emperor Dewu also spent a lot of exercises to kill it.

In Li Chen's imagination, if he cultivated this Thunder Demon True Scripture to a high depth to obtain the ultimate Thunder Demon Body, and then combined it with his current Nine Extremes Xuanjin Body, then his physique would definitely reach an extremely terrifying level.

Buzz!

Li Chen sat cross-legged, running the Thunder Demon Sutra, and at this time, a trace of free thunder power began to gather from all directions, and the thunder power in the entire room became extremely rich.

Even because of the gathering of the power of thunder, the room became brighter and brighter, like day.

And Li Chen was in it, his hair began to stand upside down one by one, and his clothes were also bulging, looking very weird.

But at this time, he was concentrating, and he was not distracted at all by the changes in the room and himself.

Gather the thunder of heaven and earth and shape my true body of thunder demon.

Running the Thunder Demon Sutra, Li Chen felt that a trace of numbness began to occur in his body, and every meridian muscle and bone, every cell opened its voice to absorb the power of thunder between heaven and earth.

His whole body gradually began to become a little paralyzed, and there was an electric current circulating in his internal organs, between his limbs and hundreds of bones.

The power of the thunder gradually increased, and Li Chen became more and more uncomfortable, this thunder washed over his body, and he had to challenge his limit again and again.

It was as if he had really been struck by the thunderbolt now, and his body was being destroyed in the thunder, and each impact would be stronger than the last, and it seemed that his will would not stop without destroying him.

What made Li Chen feel even more uncomfortable was that in addition to the power of thunder, because he himself had cultivated the Vermilion Bird Divine Technique, there was also a rejection at this time, and the two forces were repelling each other, looking for a balanced coexistence.

And before this balance coexists, the two forces will continue to fight in his body, constantly destroying his body, and the accompanying terrible tearing sensation will make him continue to break out in a cold sweat.

Again and again, he felt like he could barely hold on.

"If I don't become a demon, how can I become a thunder demon?" But Li Chen was reminding himself that if he wanted to cultivate these peerless exercises, he must bear what ordinary people can't bear before he is qualified to have them.

Enchanted, enchanted.

Some people say that obsession becomes a demon.

Only by always insisting on one's own beliefs can one become a demon.

The whole room was already shining with lightning light at this time, although it was caused by lightning protection materials, but some places were already slightly dark.

Li Chen persevered.

Time passed slowly, and it was about to reach dawn.

"Thunder is my body, and I am the Thunder Demon. Please thunder add to my body, and refine my body into the body of the thunder demon!" Li Chen's hands suddenly changed, the Thunder Demon Sutra urged with all his might, and there was thunder in his eyes that was constantly hidden, and then all the thunder in this room flashed, rushing towards his body like a tide.

Bang!

It was as if a thunderclap was exploding, and the entire inn could hear it, and then the whole room gradually dimmed, and it seemed that all the thunder had disappeared.

Heaven and earth fell silent again.

For a long time, Li Chen slowly opened his eyes, and there was a flash of thunder in his eyes, as if there was infinite thunder in his eyes, which reminded people of the clouds that suddenly shook when it was raining heavily.

And his head began to be lowered slowly, and he could faintly see that there was a thin layer of thunder light on the skin of his body, which had not been completely retracted into his body for a long time.

"This Thunder Demon Sutra is finally getting started, and this kind of feeling is not bad. Li Chen smiled slightly, and then stretched out his hands.

At this time, his hands, one palm was a flame rising, and the other palm was a thunderbolt beating......
