A complete mess, that's how his body condition right now.
Kevin kept staring at the sealing of his cultivation room for half an hour before regaining his focus and examining his body again, and to his surprise, his body was perfectly healthy and it become even more healthy. He just found himself covered in blood, sweat, and a lot of impurities that he didn't know even existed after all the torture he went through in the previous Body Strengthening Realm.
After taking another half an hour to check his for anything dangerous or concerning, he only found that the second core in his heart turned black and was more solid than the core in his lower dantian, he at first was afraid of sending energy to check on it again fearing anything strange happening again but to his relief and disappointment, nothing happened.
Relief because he will not experience the same pain twice in a row, as for the feeling of disappointment, it streamed from not being able to gain any information on the core as his energy got absorbed in the core with no feedback of what happened.
Feeling frustrated he decided to ask the only entity that should know what is happening here since it was because of it that something like this happened.
"What the hell happened to me, System?" the only thing that would know what happened would be the system that has been inhabiting his soul for a long while.
[You should check the system's notifications Host] said the System robotically.
"Then show me what you were talking about," said Kevin with a raised eyebrow.
[System asks permission to unseal the previous reward]
[….]
[..]
[Permission granted]
[Vial of Chaos is rewarded to the Host]
[Warning]
[Warning]
[Host too weak to use it by himself]
[System asks for system's assistance to seal it in the second core]
[Permission granted]
[Waiting for the Host's permission]
[Yes][No]
[Host gave his permission before]
[Proceed with the operation]
[….]
[….]
[….]
[Transplanting the Vial of Chaos succeeded]
[Congratulations Host for taking a step forward in your path to Supremacy]
"Huh, What the hell is the Vial of Chaos?" I asked with a stunned expression on my face.
[Here is the explanation]
[Vial Of Chaos: Vial made of special materials found after an apocalypse of a Universe in the past, It is used to contain a piece of Chaos Fragment that is only available at the creation of the Universe.
The Vial is crafted after eons of hard work by a Primordial being who put a lot of effort into creating something unique to be used by *#*##*#.
Current status: Sealed inside the Second core of the Host
Reason: The host is too weak to use it now]
"What the hell is this? This doesn't explain anything, it confused me more" Kevin asked with bewilderment written all over his face.
Apparently, the System took pity on him so it started explaining to educate its ignorant Host
[Host, you have a piece of Chaos Fragment which will produce Chaos Energy in your body that will slowly affect every aspect of existence until you can completely form #*#&$ of #$*&@ in your body]
"Form what again in my body?" Kevin asked again since he couldn't hear what the system said.
[Oh, I shouldn't say this information to you now, you will know when you become stronger and rise your cultivation level]
"Then, How is this Chaos thing useful to me when it is sealed," Kevin asked with an irritated tone.
[I can unseal and you will die immediately if you want it]
"I didn't say anything about unsealing it, I only asked what usefulness it has"
[With each Breakthrough Host, the seal will allow a few strands of energy from the Fragment of Chaos to slowly infuse into your body like what happened before]
"Fuck, will I have to bear that kind of pain again?" asked Kevin in a voice mixed with worry and fear as the pain he felt at the time was more terrifying than anything he experienced before.
[No Host, this time the strands of energy penetrated your body in preparation for the future, there will be more essence fused with you to upgrade your bloodline, physique, talent and everything about you will become better]
"Then this is the long-term benefits, what are the immediate benefits, it can't be I didn't get anything noteworthy, right?" asked Kevin again with a forced smile.
[You should know what happens when you break past the golden core realm and reach Will Formation right?]
"Are you talking about the sea of essence that will take shape in my lower dantian as my energy reserve at the time?" Kevin asked in confusion since the Core Formation realm is divided into 3 small realms: False then Solid and finally Golden, each one of them is divided into 4 small stages.
After Golden Core Realm a cultivator will detonate their Core in the dantian to form their Mortal Will, something that will help in the future stage of cultivation and as when a cultivator forms a core in the Core Formation Realm all the energy in the body would be stored in their core and can be used by channeling it from there in their body, but after breaking through to Will Formation Realm the energy in the core used by cultivator will form a sea in the lower dantian which would help a cultivator channel energy outside his/her body by using martial skills with the elements in the manual.
[Yes Host, A normal cultivator would only be able to channel 2 or 3 different energy essence from their sea to not affect the laws they would cultivate in the future but you are different Chaos energy slowly will affect the lower core in the coming stages before reaching Will Formation Realm to enable you the usage of practically all types of energy out there as the Chaos energy is the beginning of all types of energy]
"Fuck, isn't that overpowered?" asked with a stunned expression on my face.
[Yes Host, but if you use all kinds of energy types without letting your body adapt you will die a dog's death] as to throw a bucket of cold water on Kevin to wake him up from his fantasies so as not to kill them both.
[Also Host, you shouldn't use all of them in front of the public to not get yourself killed] added the System.
"What do you mean by that?" I asked with a curious tone.
[Imagine someone capable of wielding all kinds of energy appearing in the Universe, Do you think all those Old monsters from other races would leave you alone? Even your mother won't be able to protect you from them all, so practice with caution Host]
