MTL - Back to My Dad’s High School Days - Chapter 42 got engaged

A loner boy, who’s always loved escaping into his RPG world, suddenly finds himself living as one of his game characters. But instead of becoming his favored fighter, he’s in the body of his second avatar—a support mage! Though he’s used to playing both roles, being the mage in real life is a whole new challenge. Now he must rely on his knowledge and skills to navigate this unfamiliar reality and survive as the game's “support.”

Sure, the world is ruined, but I’ll live my own way. Of course, luxuriously and gorgeously.

In the rebirth, in order to prevent the tragedy of the previous life from happening, Bai Yu decided to rush to the [Tower of God] at any cost, and face everything together with his sister!

However, Bai Yu, who was bound by the system, mutated his bloodline, and transformed into a black-scaled python seems to be developing on a completely different path from his previous life…

- Description from novelbuddy

Initially, Lin Mo intended to become stronger through cultivating diligently. However, he discovered that staying idle was more comfortable. Most importantly, he could level up by doing nothing! Since he could achieve his goals by lying idle, why would he trouble himself to stand and work?

Lin Mo transmigrated to a martial arts world and realized that he had no talent in cultivating at all. Fortunately, he awakened the Idle Upgrade System. He could become stronger by staying away from the rat race and enjoying life.

Lin Mo lamented, “It’s not that I don’t want to work hard, but truly, there is no opportunity for me to do so.” As such, the most bizarre Martial Arts Saint in human history was born.
