As Damien lay there little did he know that this was what happened when someone under the age of 10, who had an incredibly high aptitude for Devil Cultivation, completed the Limit Breaker Stage of the Immortal Devil King Technique.
It was called the "Blood Cocoon" it was the only way to get Royal-Ranked Devil Genes and Limiters because the other way was through making the genes and limiters out of Devil Qi which you couldn't guarantee the quality you'd get.
Inside the cocoon, Damien was peacefully asleep, while the Blood Cocoon got to work and started inserting the Royal Grade Genes and Limiters, first it conjured up a few drops of blood out of Devil Qi, they were a mixture of Red and Black and gave off a domineering pressure but despite this the droplets still looked beautiful in their own way, like a unique gem that is much more precious compared to any other gem in the world.
Suddenly, the 5 droplets spilt off and went to 5 different places, not very surprisingly they went to the place where the main chains were on the Muscles, Bones, Organs, Brain, and Heart, they then merged with this places.
When the blood reached the muscles the blood began to spread throughout all the muscles in the body, seemingly endless as it drenched them all in the red and black blood making them stronger, denser and also more durable while also boosting their potential to immeasurable heights.
Next the blood that reached the bones started doing its job, the same thing that happened with the muscles, happened to the bones, they got stronger, more durable and denser, leaving them with a red and black sheen, it then delved deeper into the bones, reaching the marrow and increasing the bone marrow's ability and efficiency when it came to making better red blood cells, white blood cells and platelets, increasing Damien's immune system, recovery ability, and overall regeneration.
With the organs it washed and quenched them of all the impurities that even taking off the Human limiter couldn't get rid of, this made them much more vibrant and lively looking and it even sent them into overdrive after overdrive until they worked leaps and bounds beyond what they could once do prior to the upgrade.
It did all this while also increasing the lifeforce and vitality they gave off to immense proportions.
The Brain was drenched in the blood and started producing more and better neurons and the synapses between each neuron were made more efficient and better at delivering information between them, this increased thinking speed and reflexes in general, as the blood started to spread from the Brain to the rest of the nervous system, it boosted Damien's innate reflexes to incredible levels.

And finally, when it reached the Heart, it made the Heart go through a qualitative change along with the blood and all of the circulatory system.
It made the Heart much stronger than before, allow it to pump more blood around the body at a quicker pace, the blood was changed so it carries more energy around the body in a more efficient way, it would nourish the muscles and the body more.
It would now carry more oxygen to the rest of the body and by working hand in hand with the enhanced Lungs the changes had given Damien, the blood could now carry an amazing amount of oxygen, giving Damien incredibly high stamina and finally the circulatory system was made more durable to put up with the large amounts of blood and pressure that it's going to have to withstand from the Heart being upgraded and it's new output.
As these changes are happening, something else happened in Damien's body, a green fluid that gave off a weak aura was slowly working it's way out from the inner parts of Damien, if he was awake and saw this, he'd know what it was instantly- It was the lesser parts of his Human DNA.
As the DNA came out of Damien's body, it was instantly torn to shreds by the Blood Cocoon and used as an energy source for the creation of a red and black liquid.
The liquid being made gave off an aura of slaughter and a weird feeling of ravenous hunger, this was the Royal-Grade Devil DNA and as the DNA was finished, it slowly seeped into Damien's skin and into his body and started to improve his genetics and make his body growth rate and potential even stronger than it already was before.
As he was in the Blood Cocoon, his whole body was remolded, this was the second part of the Immortal Devil King Technique, the Body Remolding Stage, nothing major had happened yet, but over the next few years, mainly when he's in puberty, his body will grow stronger and stronger and more like a Devil to a certain extent but not to the point where he looks like a Devil, just that he has the internal workings of one.
2 Hours Pass~
The Blood Cocoon that had dried started to crack and fall apart, leaving only Damien lying there, as soon as the last piece of the cocoon fell off, Damien's eyes shot open as he tried to stand up as quick as he could--
*Crash*
--Unluckily for him, during the past 2 hours his strength has increased incredibly, so he used too much power and hit the ceiling when he pushed off the ground
"Ah! Shit, why'd that happen?" As Damien cursed he got up and noticed something was a little different.
'Wait...am I taller?'
In a hurried and anxious manner he went over to the mirror next to him and was shocked at what he saw, seeing the person he saw in the mirror and the power that he could now clearly feel pulsing through his body every time his heart beat, he was sure about what happened when he passed out and what it meant--
He'd become something more than Human.
