Time Travel Theory

What will happen if a handsome modern man travels back to ancient times? The moment he blows out the candles on the day he turns 21, accompanied by Lin Xuan's laughter, he travels back in time. As a man who is familiar with poetry and books and is proficient in 108 musical instruments, he has been preparing for time travel since he was 8 years old. With no less than a hundred time travel novels, Lin Xuan successfully built himself into an all-round academic master. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
