657 The Mystery of Xander's Birth!

Old Maddy said, "I don't know why he was chosen, but your mother told us at the time to choose the smartest one. That's because the serum she gave you improved one's genes. Even if it was passed on to the child, their genes wouldn't be modified much if the child was born very smart. This way, if the serum is unable to do what it's supposed to, it will become ineffective. I would think that is likely the reason why."
