Alexander is a top tycoon in America, with countless wealth under his name. Unfortunately, he is already 90 years old this year, and his life is coming to an end.

However, just as he was prepared to face death calmly, a system descended upon him and assigned him a mission: to establish a massive harem.

Alexander said, “At this point in my life, the only thing hard in my body is my bones. Some abilities haven't been used for decades.”

System replied, “No problem, this is a magical blue pill. After taking it, you will have amazing power!”

Alexander said, “In that case, I won't be polite!”

Please note that this is a harem-type novel, where the MC will build an incredibly large harem team, and this will become the goal of his life-long struggle.
