Can you recommend a sci-fi novel where the protagonist wakes up in the future world after sleeping for 50 years and still looks the same?

Yes, this book was called "Fight, Lord Ancestor". It depicted the year 3018. The protagonist, Han Tang, slept in a human cryonic cabin for a thousand years before being unfrozen and released. In an instant, he arrived at the magnificent era of the universe. The age on the ID card changed from 21 years old to 1021 years old, but it still looked the same. Do you want to see the protagonist's adventure in the future world? I recommend you to read this novel ~ I hope you like this fairy's recommendation. Muah ~
