The moment he pressed yes, the heart stopped for a short period of time before it started beating again, but this time it was glowing.

What followed next was the golden vessels started moving closer to blood vessels while glowing too.

They didn't have too much trouble reaching them as when they were made they were made parallel to blood vessels, this in return made it so that the length of blood vessels and the mana vessels was equal, which made it easier for the merger to be done without trouble.

When they merged the heart started beating faster than usual due to the volume it needed to push in one vessel being doubled at once but this was only for a short period of time because the runes on the heart started moving and changing their arrangements assimilating with the heart completely.

Making the heart look like zebra stripes but in gold and red. Normally when you mix gold and red liquids, the result becomes orange-y brown, but due to the golden liquid being mana it overwhelms the red color of blood turning all the liquid into gold color just like it was before.

But this golden color could only be seen by people who have magic vision, for those with normal eyes red is all they will be able to see.

With the mixing completed, changes started occurring in the body. Organs started glowing as the RUNIC MANA BLOOD started circulating in them making them turn into golden-red stripes just like the heart but dimmer.

His mussels started strengthening and healing the damage they had from daily sports, removing scars from the body.

The changes to the body occurred over the period of the month in which to the outsiders eye he was asleep.

...

Right after the changes began inside the system made room.

Aron started recalling what happened.

"Looks like I overlooked security due to getting used to living normally most of my life" This was his first mistake since he became very rich in the course of days his mindset didn't adapt to think like rich people.

And before he could realize that he was attacked.

"The first and one of the cheapest things I bought from the system shop, caused some people to nearly kill me" He remembered when he bought BugZapper due to it being the cheapest and it being on the same field he was learning before expulsion.

But despite it being useless from the system's eyes to the people of this world it was way too powerful of a tool to just leave it in the hands of a kid.

To someone it was important enough to send a person to steal it from him.

'Who might it be?' He asked himself while he started listing possible suspects.

'All security companies should be considered, countries that didn't receive the program before its public release or anyone powerful enough to know that I'm the maker of the program and would want to have it on his hands' when he finished listing the suspects he realized there was no use in even trying because the number of suspects exceeded his comprehension.

'How do I prevent it from happening again?' He asked himself, making sure that he learns from his mistakes.

'Looks like I have to buy a security company after I leave the hospital, I need to change the house too to one where perimeter security can be provided without having any difficulties' with those ideas as a starting point, he began planning on how he can prevent something similar or more deadly from happening to him anymore.

"As for other measures I will need to be awake and have current information to be able to decide what to do with them" With that he decided to sleep on the bed made for him by the system.

He didn't leave it because he wanted to spend his time there thinking about his other future plans, and not waste it by just sleeping while waiting for the system to finish its modifications on his body so that he can wake up and leave the hospital.

.....

A month passed like that and Arons body was in its final phase of upgrades as only one organ remained,

DING!!!

[

YOU WILL ENTER AN INDUCED COMA DURING THE BRAINS UPGRADE IN 5 MINUTES

]

And it needed him to be in coma as doing a brain upgrade while he was awake will be the same as upgrading a computer chip while it's on: It is a recipe for disaster and nearly certain death.

He prepared himself and waited for the five minutes to finish.

DING!!! 5..4.3...2..1.0

With that he lost his consciousness and the liquid started moving toward his brain, but this was done differently than how it was done to other organs.

The moment the Runic mana blood reached near the brain it evaporated, turned to gas and started surrounding the brain creating a golden cloud around it.

The density of the cloud continued increasing while the evaporating RUNIC MANA BLOOD started being replenished by the heart as it was being drained much faster than the usual amount used for the upgrade of other organs.

The golden cloud was entering the brain though slowly, as the system needed to be careful to avoid harming the brain and causing the death of the user and itself.

It controlled the golden cloud making it enter the brain in a wave pattern, enhancing every part it passed while losing its energy and by the time the wave reached the center of the brain, it upgraded that part while using the last of its energy.

This was followed by another golden wave doing the same thing, followed by another, then another and another...

The enhancement were slowly but surely being made to the brain while making sure the owner doesn't become a psychopath or a mass murder due to the systems mistake.

This was to be done until the last of the golden cloud is spent, as for what enhancement he received we will only know after he wakes up.
