A Clichéd Beginning: Did I Transmigrate to a Fantasy World?

[No mindless protagonist + No System + Slow-Burn Power Fantasy + Cunning + Decisive and Ruthless]

Lin Che was an ordinary high school student on Earth whose greatest hobby was reading fantasy novels. He never expected to transmigrate to a fantasy world. A good-for-nothing protagonist whose engagement is broken off right from the start? Isn't that a little too cliché?

What era is this? He doesn't even awaken a System, just get a ring? Fine. You cultivate immortality; I'll study physics, chemistry, and math, then stand at the summit of the martial world. Seems perfectly reasonable, right?

Science and technology are the primary productive forces! (There'll be a tiny bit of physics, chemistry, and math, but it absolutely won't get in the way of your reading or the fun!)

But life is unpredictable. Will things really unfold the way Lin Che imagines?

There is a female lead, and no heartbreak, so enjoy without worry.
