Room 4019, the smell of smoke is choking.

Sister Huan didn't know at all how hard she had dealt Ling Chen by teasing Ling Chen.

"This intensity of stimulation makes you unable to stand up, you are really useless, bro. ”

In the smoke, Ling Chen seemed to be babbling.

There were already more than a dozen cigarette butts in the ashtray, and Ling Chen took a heavy puff, leaving only a cigarette butt in his hand.

pressed it into the ashtray, and tried to take out another one to continue to light it, but he took out an empty one, and most of the pack of cigarettes had been smoked into an empty cigarette case.

Crumpling the cigarette case and throwing it into the trash, Ling Chen stood up and blew into the air sharply.

Most of the smoke in the room was blown away by him, and Ling Chen also swept away the previous decline.

"Isn't this the result of a long time ago? What kind of decadence is pretending?"

Ling Chen muttered as if deprecatingly, walked to the window, and opened the window.

Then, he turned off the lights and sat cross-legged on the balcony of the room.

Cultivating every morning and evening has long become his habit.

Coming out of the ancient martial arts realm, he took the train for two nights, there were many people on the train, and there were two people with children in the carriage where Ling Chen was, so there was no way to cultivate at all.

Last night, because of Su Jing's matter, and because she was really sleepy, her cultivation also fell behind.

He hadn't cultivated for three whole days, which had never happened before since Ling Chen became an ancient martial arts cultivator.

After running the Pure Heart Technique a few times to eliminate all the messy thoughts, Ling Chen began to run the Mind Method of the Transformation Sect to refine his body.

Gu Wu's cultivation has reached the stage of dark energy, even if he has basically mastered the power of his own qi and blood, and used his mind to guide his qi and blood to wash and refine his bones, when the impurities of the limbs and bones are tempered clean, even if he has reached the late stage of dark energy.

Before going to Sanssouci Valley, Ling Chen's limb bones had been tempered, and now, he was going to start refining his skin.

Bright energy is from the outside in, and dark energy is the opposite, from the inside out.

To temper the skin, in addition to improving the toughness of the skin, the most important thing is to improve the sensitivity of the skin.

The most important sign of the breakthrough of dark energy is whether or not you can perceive the aura between heaven and earth, and absorb the aura through the ancient martial arts cultivation method, and store it in your own meridian dantian.

Perceiving the aura between heaven and earth is through the skin, and the skin must be tempered to be extremely sensitive, so that it is possible to perceive the existence of the aura.

Of course, this has a lot to do with talent, some people can perceive the aura of heaven and earth after cultivating to the peak of the late stage of dark energy, and some people will take more than ten years to break through to the realm of transforming energy, and even those who are not talented enough will stop at the peak of the late stage of dark energy for the rest of their lives.

Ling Chen took off all his clothes and went naked.

Quenching the skin starts from the chest, the skin of the chest is naturally more sensitive, if the skin of the chest can't sense the existence of the aura of heaven and earth, it basically has nothing to do with the transformation of the energy realm.

The mind works, and the mind guides the qi and blood to rush to the chest, and the blood seeps out from the pores of the chest.

At this time, if someone was there, they would find that Ling Chen's entire chest was full of blood, and it was bloody!

But two seconds later, the blood on his chest was gone.

This is Ling Chen's sucking technique, sucking the spilled blood back into the capillaries in his chest.

The process of refining the skin is to repeatedly press blood out and inhale through the pores, wash the skin with qi and blood, and at the same time quench the pores.

If you perceive the aura between heaven and earth, when you condense and absorb the aura, the aura enters the meridians through the pores.

Half an hour later, Ling Chen stopped refining.

It's not that he is lazy, refining his skin, the consumption of physical strength, energy, qi and blood is very large, with his cultivation in the later stage of his dark energy, half an hour of full tempering is already the limit.

However, even if it was only tempered for half an hour, the effect was obvious, and Ling Chen's quenched skin left a black layer of impurities.

Pull a few paper towels and wipe them, and the paper towels immediately turn into black paper balls.

Ling Chen stood up and was about to go to the bathroom to rinse off and sleep, but he suddenly shuddered and sat back down.

"Aura, the aura between heaven and earth, how is it possible! I am only in the late stage of dark energy! How is it possible to perceive the aura of heaven and earth!"

"But...... Those energy particles floating in the air are not heaven and earth aura, what could they be?!"

After feeling it carefully for a while, Ling Chen suddenly let out a low roar.

"That's right! It's the aura of heaven and earth! Lao Tzu actually sensed the aura of heaven and earth so early!"

After roaring, Ling Chen immediately activated his mental method, trying to condense the aura floating in the air.

It is estimated that the consumption of refining the skin is too great, the ancient martial arts heart method is not working smoothly, Ling Chen did not condense those scattered energy particles, but only let those energy particles move, a gust of wind blew, and the energy particles escaped.

Although he was unable to absorb the slightest trace of aura, the unexpected perception of the existence of aura also made Ling Chen excited.

Originally, he was ready to take a bath and sleep, but now, he was completely sleepy and fell into deep thought.

After he finished refining the bones of his limbs, it took less than two months, and the skin on his chest had only been tempered five times, and normally speaking, he could not perceive the existence of heaven and earth aura.

Of course, to perceive the existence of heaven and earth aura, in addition to constantly refining the skin and improving the sensitivity of the skin, it is also related to the strength of the individual's qi.

The strength of the qi sense, that is, the talent of the ancient martial arts cultivators, of course, is only part of the talent.

The sense of qi is strong, at least it can ensure a breakthrough and turn into strength.

Only by breaking through to the realm of transforming strength can one be regarded as an ancient martial arts cultivator in the true sense.

Ling Chen didn't know how long it took the ancestors of those top sects in the ancient martial arts world to break through from dark strength to transformation strength, but he heard Master Ding Yuanbai say that it took seven years for the master to go from the peak of the late stage of dark strength to transformation strength!

Even if it was the master of the Transformation Sect, after reaching the peak of the late stage of dark energy, it took nearly four years to perceive the aura of heaven and earth!

And Ling Chen, it only took him two months!

This is absolutely unique in the history of Huayimen!

I'm afraid that even in the entire Ancient Martial Realm, no one can perceive the existence of heaven and earth aura in such a short period of time!

What's more, Ling Chen had only refined the skin on his chest, and he had only refined it five times!

What's even more terrifying is that this is in the secular world, and the density of the aura in the secular world is completely different from the ancient martial world.

Moreover, this is in the city, where the population density is high, and the aura of heaven and earth is even thinner.

Human beings are the spirits of all things, even if they are not cultivators, they will not take the initiative to condense and absorb the aura of heaven and earth, but will passively consume the aura of heaven and earth.

Moreover, the city is full of reinforced concrete, and the number of aura is pitiful.

However, it was in such an environment that Ling Chen, with his cultivation in the late stage of Dark Energy, had already sensed the existence of Heaven and Earth Aura!

He had only just begun to refine his skin, and it must be nonsense to say how sensitive his skin was, so it was undoubtedly due to qi sensitivity.

In the later stage of dark energy, you can perceive the aura of heaven and earth in the city of the secular world, and this sense of qi is no longer powerful to describe in two words, it is simply against the sky!
