No system + Rebirth + Time travel from American TV series + The Big Bang Theory + Lighthearted and funny + Academic genius + Slice of life + Verbal banter

Chemistry PhD Dai Jun is unexpectedly reborn in 2007, becoming David Zhou, an Asian physicist in the American sitcom "The Big Bang Theory." Using his knowledge from both lives, he narrowly lands a job at Caltech, becoming a colleague and neighbor of Sheldon and Leonard.

As the plot unfolds, Leonard falls head over heels for his beautiful neighbor Penny, only to be humiliated by his ex-boyfriend with his pants pulled down. David, a reborn individual, has a brilliant but ultimately flawed idea: find out the model number, buy Penny a TV, and give it to her as a hero?

Sheldon: A logical dead end! Morally depraved!

Leonard: For love, this plan is perfect!

Thus, the Frankenstein's monsters embarked on a hilarious and absurd journey to "change the TV".

From the Victorian throne to the shadow of the Cold War Iron Curtain, this is an epic of the Kingdom of Romania spanning a century.

Eder, a modern man, was reborn as the Crown Prince of Romania. With his visionary foresight, he refined oil, strengthened the military industry, and promoted reforms. He made precise bets amidst the turmoil of two world wars, transforming the small Balkan country into a regional power that attracted worldwide attention.

However, the real test began after his abdication. His son, Michael I, struggled to protect the legacy left by his father under the Iron Curtain of the Cold War. Faced with Soviet pressure and the ambitions of powerful ministers, the crown was destined to fall. But the Hohenzollern bloodline never abandoned its homeland. Decades of exile allowed them to forge the national spirit overseas; in times of great upheaval, they returned to rebuild the nation's backbone as uncrowned figures.

This is not only a royal legend, but also an immortal epic of a nation's struggle for survival, strength, and self-discovery amidst a century of upheaval in modern times. How did a family that lost its crown achieve eternity in another way? The answer lies on this land they deeply love.
