Reborn with the Skill-Copying Mind

Alex, a soul reborn into 1940s America, faced a crushing reality: his advanced mind was trapped in a weak child's body. Even his perfect memory, capable of recalling every detail, felt useless without the physical capacity to act. Then came the miracle. A flash of memory, a burst of raw potential, and he could perfectly simulate any skill he’d ever witnessed – from playing a master guitar piece to advanced martial arts. This wasn't just memory; it was muscle, reflex, and pure skill, instantly imprinted. But this god-tier ability had a price: his fragile body could only sustain it for mere seconds. Now, armed with a forgotten 21st-century workout, Alex races against time to forge the perfect vessel. Can a child's body truly contain the ambition of a reborn polymath ready to conquer the 20th century, or will his physical limits shatter his dreams before they even begin?
