His daughter died from an accident and he created his new daughter from the dna from which he got from the dead body of her daughter.
He created a new daughter that looked exactly like her daughter that died, an exact replica to be exact. because he just don't want to be alone and never forget about his daughter as he don't accept that she died.
Because his wife left both of them with a rich young ceo that owns one of the largest companies in the world. And to make matters worst the company that he worked for broke ties with him, even thought he provided alot of contributions to them that helped humanity reach another hight of technological progress.
Now he was left with her daughter but she had died. He developed alot but never had tried creating weapons for war when he tried creating some he became successful, but when he tried signing up he was not hired.
The daughter that he created woked up from the pod that nurture her body to grow to that of the previous daughter's state. When she was before dying with a complete healthy body rid of any illness and disseases, unknown to this poor father of her's she was just not any normal daughter even when enchanced with this body.
She was no ordinary girl born from the dna of the daughter of the poor father, she was a reincarnator who took over this body.
