Tensei Shitara Slime Datta Ken (WN) - Prologue

Ye Chen, once the unrivaled immortal standing at the pinnacle of the cultivation world, fell at the final hurdle—his last heavenly tribulation. Struck down by the wrath of the heavens, his body was destroyed, his cultivation shattered. Yet, instead of vanishing into oblivion, his soul defied fate itself.When he opened his eyes again, he was no longer in the vast cultivation realms but in the familiar yet distant world of modern Earth—inside the body of his younger self during his high school days. Armed with the knowledge and power of an immortal, he would rise once more, overturn destiny, and reclaim his supremacy in this new world.

Yuki, a high school junior, dies heroically saving a stranger and is reincarnated in a fantasy world, where he discovers an extraordinary and unrivaled power.

I am the sword.
Killing a man amidst a thousand miles, no one dares take ten steps.
Killing a man amidst a thousand miles, no one can take ten steps.
Killing a man amidst a thousand miles, ten steps? Not possible!
I am the sword, the sword is me,
On the path towards heaven, each shall wield their own.

Lin Xiao was addicted to reading Qidian novels. He always fantasized that he would have a day when he could transmigrate and then embrace beautiful women all over the whole world, becoming the strongest person in the mainland.

After he really transmigrated, Lin Xiao stubbornly always believed that he was a protagonist until he met Ling Luo.

Only after being killed by Ling Luo did he know that he was only a cannon fodder villain in a novel.

When he restarted his life and hatefully wanted to oppose his fate at least once, he was ruthlessly crushed again.

Okay then… since a protagonist was determined to be like this, he wouldn’t oppose a protagonist anymore…

The two of them were similarly straight guys…

When he restarted his life again, Ling Luo unexpectedly suffered an Love Herb’s poison…

Lin Xiao internally cried as he looked at a certain person who tied him onto an obelisk in the back and thought, who could tell him what this was all about?
