Absolute Immortality

Basically when inside your own universe you gain Universal Manipulation and Absolute Immortality. You only posses those powers when within your universe and not other universes(If you were somehow were to create a way to travel universes). Besides that the world is your oyster, you can do whatever you want.

So with all the healing and or regeneration powers of the Absolute Category. is there any power in which it would allow you to heal another person. for example.

If a person with Absolute Immortality forced someone to drink there blood. would this heal them, or even make them immortal to a certain point?

I'm making a story where some people in the world have varying immortality ranging from semi-immortality to the main three characters who have absolute immortality. There is a business/company that hires only immortal people with regenerative healing factors and above but I'm having trouble figuring out what the company does and what the jobs would be.

So what do you guys think this company and varying jobs should be?

It’s a powerful eye that the pupil is just the infinity symbol, and the powers that grants its user: Almighty mind, Meta crafting, Absolute potential, and Absolute immortality.
