Youkoso Jitsuryoku Shijou Shugi no Kyoushitsu e - Volume 4.5, Prologue: Even so the Summer Vacation heads towards its end.

“Was trying to forget my past and live a peaceful life… a mistake?”His twentieth birthday was supposed to be a celebration, not his final moments—bleeding out on a bed, betrayed, and left to die.'Taking the life of a ‘good’ person makes you a murderer, but taking the life of a ‘bad’ one makes you a savior… Why?'As death embraced him, he whispered his final words—“The world’s kindness, right till the end..”…Only to wake up in an unfamiliar body.“Wait… I’m Noir Ravenlock?”A doomed heir, born to rule the world yet bound to a fate engraved with blood.In a world where morality shapes strength, survival demands more than just power—it demands understanding.And Noir, a man or perhaps a demon who once saw the world through twisted eyes, may just see something no one else can.

Chen Xi looks at the soldier who just threw a rock weighing a few hundred kilograms away and looks at the sky speechlessly. Is this really the late Eastern Han Dynasty?It doesn't make sense to see Lu Bu single-handedly cut through the ten-thousand-strong cavalry.Zhao Zilong ends up truly possessed by a dragon soul. Is he really human?Dian Wei single-handedly defends Cao Cao as they storm out of the enemy camp and slaughters a few thousand cavalry of the enemy. His combat strength is off the charts!Is there something wrong? Chen Xi touches a goose feather fan and fans it. A strong gale blows and he sighs.“This must be some mythical story, right? Even I'm not normal anymore.”

“Yan,” the protagonist, was brainwashed by the emperor and lived as his puppet. After finding out he was being played by the emperor, he planned to seek revenge, but collapsed due to the emperor’s might. He thought he had died, but when he woke up, he realized he had regressed to the time when he was a recruit. Whether to seek revenge on the emperor or to find his family. The choice lay in his hands.

This world has Fox Fairies, River Gods, Water Monsters, Great Demons and Cultivators who seek immortality.
