He found out that he is in a world similar to our own with a timeline akin to early twentieth century.

Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout.

Having reincarnated into a different world, Murong Lin found himself utterly bewildered.The golden finger system informed him that he needed to eliminate the protagonist—wait, he wasn’t the protagonist?Innocently, Murong Lin turned his gaze towards the designated heroes, a butcher’s knife clutched in his hand. Regretfully, he realized he had no alternative but to end their lives if he wished to survive.Hold on, this pig was a protagonist too? And that tree?Without any choice, Murong Lin found himself forced down the path of bloodshed.

Three thousand years ago, gods and Buddhas disappeared all over the sky, and the inheritance of practice was broken. It was not until the ancient civilization was destroyed that spiritual energy recovered. Ten thousand races took advantage of this to invade.

Five hundred years later, the human race gradually rose up and began to fight for control of the land of China, and counterattacked all races.

Three hundred years later, Fang Yi, the Lord of the Great Dao, slaughtered all clans, destroyed all the heavens, stepped out of the myriad realms, and fought against the Dao of Heaven.

In desperation, Fang Yi sacrificed blood to eight hundred small worlds, reversed time and space, and was reborn nineteen years old.

In this life, he wants to live a more relaxed life, perfect his Dao Xin, and conquer the Dao of Heaven again.

- Description from novelbuddy

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]

Worked on it, so it's all good now.
