From Human to Skeleton: Revived with Infinite System Crystals - Chapter 83: The Old Lady

When a boy in a medieval fantasy world wakes up with the memories of his past life, he discovers a secret buried deep within his mind—a highly advanced AI companion. This AI, a relic of his previous existence, holds the knowledge of a futuristic world filled with technology, science, and innovation.Armed with this unprecedented advantage, the boy embarks on an extraordinary journey to transform his medieval surroundings into a thriving futuristic utopia. From reinventing agriculture to creating advanced cities, he introduces ideas far beyond the comprehension of his peers. But his vision isn't without challenges—power-hungry nobles, skeptical commoners, and ancient magical forces stand in his way.

What do you do when you're a loser who is suddenly called the saviour of the world!? You use it as an opportunity to take charge of your own life while picking up cute girls along the way!

Han Luo is just that kind of person, a perverted loser who is suddenly told he is the saviour of the world.

“what do you mean I'm the only one!? cant you see I'm a loser!?”

“If you want to kill me then you are going to have to work for it! My life isn't that cheap!”

Join Han Luo on his journey through the post-apocalypse!

[P.S. This is tagged Overpowered because I always wanted to create someone unbelievably strong. So Han is going to become one of the damn strongest people on this entire site - not just this story. But a good story needs growth, not just a quick power dump, so he'll be a bit pitiful at first, around chapters 1-15. So please bear with me till he gets back from his first time skip. After then, you'll be in for the ride of your lives]
