Xiao Feiyang has returned to Jingwu Villa, and he has broken through to the innate realm, which is definitely a good thing for Jingwu Villa.

The group met until late in the evening before they dispersed.

Lin Yun then returned to the practice room and continued to practice in retreat.

Lin Yun packed the collected innate aura in a delicate porcelain bottle, and prepared to make it himself again, and then take it out after the innate aura to refine and break through together.

After sorting out his thoughts, Lin Yun took out the strange picture scroll from the storage bag.

This picture scroll is the secret map of the Demon Heaven given to him by Feng Kun, the head of the Feng family's compound in Fenglin City before.

"I hope this Demon Heaven Secret Map teammate helps!"

Lin Yun said secretly in his heart.

This Demon Heaven Secret Diagram is very secretive, as long as people observe it carefully, it is very likely that they will go mad because of this, even a great grandmaster-level martial artist like Li Fengqing can't control himself, resulting in a madness, if it weren't for Lin Yun's Yi Jin Jing Divine Skill, I'm afraid it would be difficult for him to return to normal.

Lin Yun tore off the circle of cloth wrapped in the surface and unfolded the scroll to the ground, his eyes staring at the painting, and his body trembled suddenly.

There is a head painted on this picture scroll, it is a hideous alien head, it is full of fangs, its eyes are blood-red, and the eyebrows are painted with two finger corners, painted with flesh and blood, a bunch of blood-red eyes seem to be able to give some kind of command to people, as long as you look at it, you will feel creepy, and suddenly lose your mind!

"This thing...... What the hell is it? ”

Lin Yun was a little surprised, this painting was indeed too weird, it was obviously a painting on paper.

But the head on this painting seems to be like a living creature, which makes people daunting and confused, and soon makes people look away, and the slightest hesitation may lead to falling into the abyss of no return.

"Interesting, it's just such a painting, am I still afraid that it won't work?"

Lin Yun didn't pay too much attention to this strange feeling, and his eyes kept staring at the head on the painting.

Soon something strange happened, Lin Yun's surroundings underwent amazing changes, the surrounding air suddenly condensed, and a cloud of black gas permeated the entire practice room, eerie and terrifying, and suddenly stretched out a head from the black mist, only to see a pair of blood-red eyes, which could make everything in the world shatter in an instant.

It's a demon, a demon from another time and space!

This is a picture with a special magical power, and everyone who looks at it will involuntarily lose control and eventually go crazy.

"This demon...... It seems to be a big devil from another time and space! It's incredible...... What kind of master sealed this demon in this painting? It makes people unable to look at it directly, and they will be crazy about it after watching it for a long time, this terrifying demon, terrifying even a real person at the Jindan level, is as vulnerable as an ant under his feet in front of it! ”

Lin Yun had just seen the true face of the demon in the diagram through this Demon Heaven Secret Diagram, and he was shocked in his heart, such a terrifying alien creature that made people feel terrified at a glance was completely beyond the scope of human comprehension.

Lin Yun had already understood that this world was far more incredible than he imagined, and only by striving to reach a higher dimension could he deliberately see and have seen strange scenery.

At this time, Lin Yun's face changed abruptly, and after he carefully looked at this Demon Heaven Secret Map, he faintly felt that his mood also began to be impetuous, and the qi in his body gradually began to become chaotic, which was obviously a precursor to going mad!

In the Demon Heaven Secret Diagram, bundles of black demonic qi continued to pour into Lin Yun's body, making him, a person who had the courage to spy on the true face of the demon, gradually fall into the abyss of no return.

Lin Yun clenched his teeth, struggled with the last thought, and began to recite the mental mantra of the Yijin Sutra Divine Skill, which is the top martial arts technique of the Buddhist sect, which can get rid of distracting thoughts, calm the mind and gather energy, and can resist the invasion of monsters.

Soon something happened that stunned Lin Yun!

"Ding, your Yijin Sutra Divine Skill has spied on the mystery of the Demon Heaven Secret Map, and has gone mad and evolved into the Yijin Sutra Demon Divine Skill!"

At this moment, a pleasant and clear system prompt sound sounded in Lin Yun's ears, and the Yijin Sutra Divine Skill he had cultivated had undergone an unexpected change under the invasion of the demonic qi of the Demon Heaven Secret Diagram!

"What the hell am I ...... What the hell! I just looked at a secret map of the Demon Heaven, and I actually made the Yijin Sutra Divine Skill that I practiced become a Demon Skill instead, which is amazing! ”

Lin Yun couldn't help but smile bitterly, what kind of thing is this!

Immediately afterwards, Lin Yun suddenly became energetic, and with the demonization of the Yijin Sutra Divine Skill that he had cultivated, after becoming the Yijin Sutra Demon Divine Skill, Lin Yun's emotions that Lin Yun could not control by the Demon Heaven Secret Diagram immediately dissipated.

Not only that, but the bundles of black demonic qi in the Demon Heaven Secret Diagram were all continuously devoured and inhaled into his body by his Yi Jin Sutra.

"Ding! Your Yi Jin Sutra Demon Divine Skill has ingested a bundle of black demonic energy, and you have made rapid progress! ”

"Ding! Your Yi Jin Sutra Demon Divine Skill has ingested a bundle of black demonic energy, and you have made rapid progress! ”

……

The continuous system prompt sound sounded in Lin Yun's ears!

The Demon Heaven Secret Map, which contains a large amount of black demonic energy, will make the Demon Heaven Secret Map seem so mysterious, and now the endless stream of demonic energy in the Demon Heaven Secret Map has gradually been refined and absorbed by Lin Yun's Yijin Sutra Demon God Skill.

Lin Yun also wanted to know what kind of changes would happen to him after refining all these demonic qi with the Yijin Sutra he had cultivated.

"Ding! Your Yi Jin Sutra Demon Divine Skill has absorbed a sufficient amount of dark demonic energy, and your main meridian has produced a powerful mutation! ”

After the dark demonic qi in the Demon Heaven Secret Map was absorbed and refined by Lin Yun's body, a pleasant system prompt sound sounded in Lin Yun's ears again.

In the next second, one of the main meridians in Lin Yun's body gradually glowed with a shallow dark color!

As this Zhu meridian slowly turned into a dark color before the light, the Gang Qi in Lin Yun's body was quickly dyed into an inky black color, as if it had been refined, and the quality of the Gang Qi became more vigorous, far more than twice as much as before, and there was also an evil and domineering meaning.

"I'll you...... My main meridian has actually transformed into a demon meridian! ”

Lin Yun was stunned for a moment.

The Yi Jin Sutra Divine Skill could originally make him change dramatically, so that his body could hold more Gang Qi, and after absorbing the dark demon qi, he also had a demonic nature!

As long as Lin Yun's body absorbs enough dark demonic qi, he can make his main meridian change into a demon meridian, and the Gang Qi will also transform, turning into an even more powerful demonic Gang Qi!
