System's Ultimate Buff

On Earth, during the Fourth World War, Doctor Dewar had been sent to the front line to treat a child, but had been killed and wounded, and she had been reborn in another world with a passion for peace.
Was it so easy to be reborn as a debtor, a renegade, an empress?
No! She was going to save the plane, knock on the cp, look at the pretty boy, talk about love!
And most importantly - she was going to finish her job and become a staff member at the Fifth Space Management Station. That would be the treatment of immortality!
