If he resorted to a limb that was 100 percent mechanical, then his blood circulation would stop short of reaching it. That would be bad because his metallic leg would be treated as a foreign object instead of a core part of his body.
Once enough flesh and bone had grown out of the original stump, he tried to restrain the creation energy as best as possible.
The autopilot that was directing its work tried its best to 'complete' the regeneration of his lower left leg, so Ves wasn't able to stop its efforts for long.
"It can't go against its own nature!"
He had to work quickly. He began to pick up lots of different internal parts that he had taken from his Unending Regalia and placed them on different spots of his half-regenerated leg.
The creation energy smoothly attached them to his naked flesh, just as he expected.
Not only that, but the parts themselves also changed and expanded as he continued to direct his intent towards the process.
Although he had no certainty that his attempt to construct a working cybernetic leg was proceeding correctly, he just had to trust in the process and have faith that the creation energy would fill all of the gaps that he was missing.
"Ugh, this is definitely the most haphazard design project that I have ever embarked upon. I still don't have a good idea what I will get at the end!"
Ves had to think on the fly and come up with new ideas and design applications on the spot.
He found out that while he was limited by the quality of the parts and materials he had available, that still left him with plenty of possibilities.
In the following hour, he stuffed lots of different miniaturized systems into his cybernetic leg.
He first added a redundant computing system. He wanted a part of his leg to function as a substitute or supplementary data processing and data storage system.
This not only multiplied his ability to process data or retrieve information that he had stored in his body, but also provided him with a backup option in case someone disabled his cranial implant.
It should be a lot harder for outside influences to disconnect him from his Archimedes Rubal bioimplant now that the creation energy had upgraded it and deepened its integration into his brain.
However, Ves could not rule out every possibility. What if an assassin planted a gauss round in his head one day?
"Wait, why leave it there? Why not not create a backup of my brain while I am at it? It's a genius idea!"
It was practically impossible to integrate a redundant brain in a human body without turning the patient crazy, but Ves didn't have to worry about screwing up the procedure under these exceptional circumstances!
"I don't need to make a backup of my entire brain. I just need to add enough brain tissue to store my most important memories and whatever else is essential."
It was a great redundancy plan. Although a part of him was already transitioning into an energy-based life form that had no need for brains to maintain his cognition, he was still a long distance away from reaching the end of this transformation.
His brain still played an essential role, and it was quite dangerous for him to rely on a single point of failure.
"Let's grow a second brain, then!"
Ves had to be clever about it. He not only had to free more space inside the organic part of his cybernetic leg, but also find a way to protect it against damage.
Somehow, he managed to squeeze in enough brain matter to include the elements he wanted the most.
"Oh, I also need to make sure it doesn't develop an independent consciousness."
He did not want his body to get taken over by an alternate Ves that was rooted in his backup brain!
Ves applied changes to his brain matter that hopefully ruled out that possibility.
Once he was happy with this addition, he proceeded to add other features to his leg. Some of them were mechanical in nature while others were based on organic components.
The most interesting additions were those that made use of both flesh and metal to accomplish a unique job.
For example, Ves added a kinetic weapon system to his ankle.
In order to make it as powerful as possible, Ves had to make most of it out of mechanical components.
What was different was the ammunition. In order to make sure he could always generate ammunition in the most remote places, he created a mechanism where his own body would grow and accumulate small spikes made out of organic bone.
This way, anything he ate and digested could be used to replenish his ammunition reserves over time!
The quality and performance of his hidden kinetic weapon would vary depending on his nutrient intake.
In order to make sure he could grow stronger bone spikes, he even went back to his digestion system and made sure his stomach could ingest and process raw metals if necessary!
As he carefully went to work on modifying his own stomach and guts, he momentarily froze as he made a shocking realization.
"Wait… am I turning myself into a humanoid version of Lucky?!"
