The first thing Jeff had to think about was what is he going for with his body build. Second was about whether or not to create a new species. Third was about his sustenance also known as a career.
First thing, Jeff needs:
Escape ability.
Greatly enchanced bodily functions (overal strenght, agility, endurance...<*>).
Armour that could whitstand extreme envirovment such as vacum of space or venus/ titan atmosphere.
Escape ability could be anything from having wings or having an ability that let's you transfer your counciousness into other being without losing memories and unique abilities.
Greatly enchanced bodily functions is what Jeff was focusing lately, basically the ideal would be strenght, agility, endurance and perception comparable to 2 primarch's combined. Charisma is unimportant, for the inteligence there are currently 2 options: create USB port from flesh to connect to computer and use it's processing power for development of new tech or create overmind which will do the same thing.
Armour should be made from mixture of bones and flesh, Because this will make it very easy to repair and could also serve as power armor and comfortable and replaceable nigh indestructible clothing <**>. Additionally the armour should have extra pair of hands that may or may not be part of original body, their purpose would be to manipulate and move easier in zero gravity envirovment.
Second thing, creating a new species would elevate Jeff's current status and he would be able to create the best species in the solar sytem if not in the universe. However there are things that need to be taken care of to even begin like: ways to reproduce efficiently, gathering of genetic material and where species could exist peacefully.
Third thing, is to decide between 3 ways of gathering money to sustain himself:
Way of stock market, it has highest risks for meager reward. Sure you can get like 50 milion dollars from it but you will also gather attention from big companies which usually don't appreciate new rivals and from criminal syndicates.
Way of solitude, it has no risk but also is the slowest to acomplish. It means faking Jeff's death and changing body to the point where living in the ocean or deep beneath the surface would be comfortable.
Way of crime, it has meager risks and meager rewards. It requires a bit of prep work and it usually garners attention from the public eyes. Which isn't good if you want to create new species or if you don't look like average human.
Some would try to add way of being good person or something, but to all those people first thing about Jeff's education and current work. It doesn't hold any reward and has risks, because since he can't die from old age how could he explain his old age?
Jeff made his choice he will try to become a creator of new race and will go with the way of the solitude with parts from way of crime.
-"[IL1] take all of food in my tenement with their current containers except fridges, also store some tap water and unload enough to fill lungs of every person except me in this tenement after those people die store their knifes then unload them above the bodies to sever the limbs. Then store the bodies and their blood."-Jeff said complicated list of commands into the air while hoping it would work. He didn't need to wait long soon he heard loud noises of suffocation.
After solid 30 minutes all of the bodies were in his inventory.
