MTL - Rebirth of the Film Emperor’s Beloved Wife - ~ 143 million thousand pets

This story unfolds during the later stages of World War II, where a man, scarred by the horrors of war, finally grasps the profound and harsh realities of the world. In this world, those at the top laugh and celebrate, while those at the bottom sacrifice their lives in futile conflicts driven by pride and meaningless ambition.A modern soul transmigrates and fuses with the original soul of a body, creating a unique and extraordinary existence. To some, he is a villain; to others, a madman.In a world steeped in cruelty, this man, determined to secure a place among the decision-makers, struggles to break free from the ranks of those powerless to control their fate. To achieve his goal, he resolves to shatter the chains of law, then the chains of morality, and finally the chains of mediocrity.

The game spoilers turned out to be fake. The characters I gathered thinking they were heroes are actually all villains. In other words, I accidentally created a villainous organization.
