Because of this demon king's curse, the original owner still has a deep study of the demon clan, and now it is cheaper Merlin.

Just rummaging through his memory, Merlin quickly found clues.

The so-called heart demon is actually a bit similar to the heart demon tribulation he had to encounter in his previous life when he was in the cultivation of immortals, and they are all the kind of terrible existence that provokes evil thoughts in people's hearts and makes people go crazy out of control.

Here we have to mention the origin of demons.

After death, the soul will fall into the River Styx, and as the river collapses and flows, it will finally be washed away in the river, becoming the most primitive blank soul, and finally being thrown back to the world to start a new reincarnation.

Therefore, the River Styx is actually a closed circle, and the so-called River Styx is boundless, so long that it has no end just because it has been circling in circles.

And on the shore of this Styx Ring, there are three places that are linked, namely the upper reaches of the Kingdom of God, the middle reaches of the human world, and the lower reaches of the abyss.

The souls of good people will be led by angels to the kingdom of God in the upper reaches to become God's people and enjoy eternal bliss.

The souls of the bad guys will be swallowed up by the abyss downstream, becoming demons and sinking forever.

Only the souls of ordinary people, who are neither good nor bad, will continue to sink in the river until a new cycle begins.

Therefore, the origin of the devil is actually those sinful souls, those already dirty souls fell into hell, the generous abyss mother selflessly shared her accumulated negative energy with them, in the infusion of the massive negative energy, the wicked people were reborn and became the embodiment of evil - demons.

Sounds great, doesn't it? The abyss is simply the savior of the wicked, not only is there no punishment, but it also gives them great strength, how generous and selfless.

But it's just what it sounds like, the abyss is hell, and the newborn demons will soon realize that this is not just a joke.

As the theology of the church prophesied, the demons of hell live in horror and despair of oppression, and to live well in that heap of wicked people, you must be more evil than all, more vicious than all, and more treacherous than all people.

So, in that cruel Gu cultivation fight, the abyssal mother was so "lost" that she was about to cry, and her body swelled sadly several times because she grew up with sin.

Hehe, that's right, the reason why Mother Abyss is so generous in giving the demons a new life is only because it is a necessary upfront investment. As long as there was a steady stream of newborn demons being invested into that abyss Gu cultivation field, then her previous initial investment would soon be rewarded tenfold and hundredfold or even thousandfold.

Maybe this is to fatten the pigs and kill them again.

And in this chaotic era, the long-term Abyss Mother has fully realized the preciousness of human resources, so she loves the people like a son, you don't see that the abyss is full of fights and riots every day, but in fact, as long as it is a demonic civil war in the abyss, it is a "friendly" exchange that will not die, even if you are beaten only a mess of meat, the Abyss Mother can rescue you back.

Of course, although you won't really die, the pain and despair of every death are real, and the negative energy spent to rescue you by the way is also recorded on your head, please repay it with double despair later.

Unless the wicked soul has been resurrected too many times, and has become so overwhelmed that it really can't be rescued anymore, don't think about resting.

In short, if you don't squeeze the despair of these demons who can't survive and die to the point that there is not a drop left, that's not over.

However, there is oppression, so naturally there is resistance, although all the evil people in the abyss, but maybe one day suddenly a prodigal son turned back to the big demon who decided to come to hell to rectify, and want to build hell into a new hell with simple customs and a harmonious new hell.

If the Gu worms are really all well, harmonious and friendly, and don't fight, then the abyss mother, who is the boss, is really a blood loss.

Therefore, proper stimulation is also necessary, just as raising Gu also needs to use blood to stimulate the ferocity of Gu worms, the same is true for demons, and it is the heart demon who bears this stimulation duty in the abyss.

When Mother Abyss transforms those evil souls into demons, the demons that are the seeds of the abyss are also planted, and as long as the new demons continue to do evil, then the seeds of the demons will take root and sprout and thrive.

The demons during the growth period will amplify the host's desires, and use their desires to drive them to continue to be evildoers, so that there will be no plot of turning back and repenting, and the order of hell will be balanced.

And when the heart demon matures, he will directly devour the last consciousness of the host, who has almost become a puppet of desire at this time, and completely replace it.

At this point, a truly mature demon was born, devoid of humanity and the true embodiment of evil.

It can be said that the inner demons are the juvenile bodies of the real demons, and the demons into which the souls of the wicked are transformed are at best just nourishment.

Well, far from it, in human terms, the demon is actually Merlin's san.

As the Demon King, the original owner naturally has a demon in his body, and even Merlin himself has seen that demon with his own eyes, and the black ball the size of a basketball he saw in the sea of consciousness is it.

Merlin had always thought that the black soul ball was the soul of the original owner, but the soul of a normal human cannot be pure black at all, even if it is a vicious villain, as long as there is still a trace of human nature, it is impossible to be pure black.

It wasn't until later that he learned about the concept of the heart demon that he knew that it was the heart demon in the original subject, only the pure demon soul of the heart demon would be so completely black, as for the real soul of the original owner, it had already been eaten by the heart demon, and the heart demon had successfully eaten the original owner, and was forming a cocoon into an embryo to prepare for the final hatching process, as long as it digested the soul of the original owner, it could be born self-consciousness based on the consciousness of the original owner, and at that time, the original owner would also turn into a real demon king, and then return to the abyss, Enter the Demon King's Palace in the depths of the abyss.

It's a pity that the poor unborn demon king embryo just bumped into Merlin from the other world at this juncture, obviously the future demon king, but still can't stop the real hanging, and was directly caught by the light of the system that protects Merlin's soul, and then swallowed it raw, and the power that the heart demon has worked hard for more than ten years has turned into nourishment for Merlin's soul, and the remnants of the original owner's consciousness that have not been completely digested by the heart demon were spit out with some disgust by the golden finger, Turned into the handsome boy who dissipated after chatting with Merlin for a few words.

However, thinking of this, Merlin sank his attention into the sea of consciousness with some weakness, and in that huge space, a small figure as black as ink sat cross-legged in a black sun.

"So, I'm not a demon right now?"

Looking at his black, shiny soul, he felt a little weak.
