MTL - Returning From Level 900 - ~ Is it right?

On the brink of destruction, I regained consciousness and found myself back in the past, 20 years ago. In order to have a peaceful retirement, I must prevent the impending doom.

Do not betray your employer;
Do not betray your companions;
do not lie;
Rather than violate it, I would rather be silent.
These are the four laws that “The Silent One” has abided by for thousands of years.

Day and night we roamed the streets of the Yordian cities,
Dressed in Chinese clothes, wearing a mask, with a long sword on his waist and a dagger in his pocket.
We take lives and receive payment.
We are as humble as ants and as noble as kings.
We hold the power over the life and death of others.
I never cared when I died.

- Description from novelbuddy

In a world where Classes, Stats, and Levels are the everyday norm, Reivyn has a secret.He was unusually aware of his surroundings from an incredibly early age, and Skills and Stats were acquired easily. He was just the son of an ordinary village family, and nothing appeared out of the ordinary on the surface. But below the surface, dreams of another life help shape his mentality and growth. Why does he have some remembrance of a past life, and what is his purpose in this new one?“Soul of the Warrior” is what I call a Semi-Isekai LitRPG. I say “semi,” because Reivyn's past life is remembered like a dream, and very incomplete. It is still Isekai, though, as he remembers enough that it directly shapes his personality and his sense of self.The System that governs the world of “Soul of the Warrior” is a combination of modified versions from Selkie's “Beneath the Dragoneye Moons” and Kosnik4's “Magic Smithing.” I have changed enough of these Systems and combined them in a way that is unique that I'm mostly sure it's fine, but I still have requested permission to use these ideas. They have both graciously granted me permission.Winner of the April Writathon Challenge.

This is the story of an ignorant scum who pretends to be a scholar and goes to the world of Meiman to slaughter various scholars and bosses.

This is also a story about pretending to be a fool instead of pretending to be an idiot.

When the heaven will entrust a hero with a great responsibility, he must first take his nickname ‘Problem’, let his online name be ‘Jiancao’, and change his character to ‘conscience’.

Except for the protagonist’s surname Mei, everything else is fine.
