I'm One Hundred and Thirty-Eight Years Old, Dressed Like a Loser

The 138-year-old future chief scientist is transformed into an 18-year-old useless second-generation rich man. His brain holds the technological tree of all mankind, and his body carries a microworld with mountains and lakes. The school beauty chases after her, the royal sister protects her, the iceberg melts, and the neighbor waits for her - they are all asking the same question: Who are you? I won't tell. I will use the next time to let this era kneel down and call me daddy.
