Ah Cheng's mud pill palace seems to be the territory of the demons. Inside, it was filled with a black mist, and there was no trace of spiritual power.

Shen Yun took a closer look and found that the mist was bubbling out.

It turns out that this is the lair where the demons are hiding.

The demons in the heart originated in the Mud Pill Palace?

Such a discovery refreshed Shen Yun's understanding. Before that, he had always thought that the demons in his heart originated from the sea of knowledge.

After thinking about it, he drove that trace of spiritual power and quickly circled the Mud Pill Palace.

It really told him to discover the source of the black mist.

There was a hard core about the size of a jujube core, shiny and shiny, like a spring, with a black earthly aura flowing outward.

Demon core? Shen Yun's mind instantly popped up with these two words.

At this moment, the little hardcore child discovered his spiritual power filament, and a circle of red light swept across the surface. Hu ——, this red light turned into a blood-colored full moon scimitar, and slashed towards the spiritual power silk.

Demons!

Ahh

Shen Yun saw it clearly, of course he wouldn't sit and be stabbed. Besides, the demons are also demons.

The patriarch has a certain amount of research on inner demons. According to her explanation in the jade slip, although the demons in the heart originated from the obsession of the monk, they were not part of the monk. To it, the monk is just a host. Once the obsession turns into a demon, the latter will continue to confuse the host, causing it to gradually sink into the obsession and cannot extricate itself. The demon absorbs the host's anger as a result. After these evil qi were refined by the inner demons, they became the evil qi of the earth.

The simpler the host's obsession, the higher the bloodline of the demon. After that, the Earth Evil Qi it refined became more and more refined.

The demon in his heart gradually grew bigger, and one day, the demon core was condensed, and it was ready to become.

At this point, the demons will rise up and devour the monks.

If the latter is defeated, it will become a meal for the demons. According to the patriarch, after the heart demon succeeds, it will suck up the host's dantian, brain and internal organs.

However, the host does not die. He can eat, sleep, walk, and move, and seems to be alive. In fact, his original mind and emotions are gone, and he is just a walking corpse. And, from then on, it was controlled by the demons.

And the heart demon light devours the host, just forming. Next, he will break away from his body, scourge more people, and create more walking corpses that he has a firm grip on. 、

In this process, the demons continue to grow...... Eventually occupy one side and become the devil.

The heart demon is the most deceptive, and in addition, it is usually hidden in people's bodies, and even if it is the current Dao Monarch, he will not be aware of his existence until he is in trouble. Therefore, it often does not take a few years from the formation of the devouring host to the rise.

The patriarch said that good and evil are not separated, and it is the duty of a monk to kill demons and eliminate demons. Shen Yunshen thought so. Therefore, from this point alone, he will not let go of this demon who is in trouble and wants to devour the host.

At this time, the heart demon initially condensed the demon core, but it was not very powerful, and it could only be contained in the host's body. It's also the best time to cut it off. Otherwise, once the inner demon can get out of the body, it will not be easy to find it out in the vast sea of people. At least it's much harder than looking for a needle in a haystack.

Immediately, Shen Yun's heart moved. Without waiting for the blood-colored full moon scimitar to approach, the trace of spiritual power "popped" and dispersed by itself.

In an instant, the full moon scimitar arrived and pounced.

The demon core flickered, and it made a soft sound.

The voice, milky, was like that of a child of a year or two.

In fact, Shen Yun's spiritual power silk did not withdraw from the Mud Pill Palace. He has already had the heart to kill this demon, and now that he hasn't done it, how can he leave easily?

This is just a suspicious array set up by him with a small newly discovered method.

Two days ago, when Shen Yun was practicing, he accidentally discovered that his spiritual power could be hidden as he wanted.

In the past, he had also concealed his spiritual power, but that was with the help of breath charms.

And this time, it was his own divine consciousness alone. Of course, with his current cultivation, his divine sense was far from being strong enough to conceal all his spiritual power. At most, it can only conceal a fist-sized mass of spiritual power.

Therefore, the thread of spiritual power, which is much thinner than a hair, is under the control of the divine sense, and if it is not seen, it will disappear.

The demons in the heart have not yet been born, and at this moment, they are all acting on instinct. It was shining just now, and it was looking for that foreign object in the Mud Pill Palace. I didn't want to, but I didn't find it, so I was naturally surprised.

After Shen Yun successfully confused the demons in his heart, he quickly activated his spiritual power, using the hidden spiritual power silk as a medium, and vigorously transferred the spiritual power.

As soon as the light sound of the heart demon fell, a large gray-white mist suddenly appeared in the Mud Pill Palace.

It's as thick as a thick porridge. As soon as it appeared, it spread with a bang. Like a little tiger, it is extremely powerful.

The little core shuddered and screamed - what the hell is this? Why is it so terrified?

The black gas mist that originally filled the entire Mud Pill Palace quickly converged.

Shen Yun was secretly surprised, and said in his heart: The ancestor said that the heart demon is cunning and fickle by nature. Now, what kind of trick is this thing playing?

While pulling the vigilance to the highest level, he drove the aura and quickly slashed through the chaos of the fog that had not had time to close.

But things were much simpler than he thought!

Whenever he was touched by his aura, the black mist swished and was absorbed.

It was as if his aura was sucking in the black mist.

No wonder the first reaction of the demon is to close it as quickly as possible!

Shen Yun's mind turned, and he was quickly relieved: the evil qi of the earth is also the evil qi. Before, he swallowed so much yin and evil qi into the dantian, and in the end, not only was there nothing to do, but he also cultivated to a great progress. Compared to that time, this idea is the amount of filling between the teeth. So, smoke and smoke, what are you afraid of!

In this way, Shen Yun naturally would not be polite to it. With the existing aura mass as the medium, the aura in the body was continuously transferred into the mud pill palace.

In front of his aura mass, the heart demon seemed to have no power to parry. No, to be precise, except for the blood-colored Full Moon Scimitar that it sent out at the beginning, after that, in the face of Shen Yun's big attack, it didn't fight back at all.

It just screamed, just dodged, just shivered in terror.

The patriarch has always said in the jade slip that the demon in his heart is bold and reckless, and he dares to cover the sky.

Is it such a bold method? Shen Yun thought it was strange.

Maybe it's a trick of the demons. He remained on the highest alert.

The battle situation in the Mud Pill Palace was one-sided from the beginning. Soon, the gray-white aura filled the entire Mud Pill Palace. The little magic core had nowhere to follow, and it let out a desperate cry of "woo woo".

What about being bold and ruthless?

This situation makes people embarrassed......

However, Shen Yun only paused slightly, and then decisively swallowed it up.

With a "bang", the demon core exploded.
