MTL - The Full-level Boss is In the Female Respect - Chapter 253 very satisfied

In a world fractured by conflict and haunted by shadows of the past, Kokushibo—the first Upper Moon demon—meets his end, only to awaken in a new life. Reincarnated as Crimson, a child born into a different family, he carries the memories of a past he cannot escape. Burdened by centuries of guilt yet indifferent to the present, he resigns himself to duty—until an unexpected bond with his newfound family begins to thaw his hardened heart. As he struggles between the weight of his past and the weight of the new life, Crimson must decide whether he will remain shackled to his former sins or embrace the possibility of peace.

The peace did not last long. After the passing of Shan He, the once Glory Empire collapsed. Various forces of Human fell into a long period of wild war for the Divine Weapon Catalogue, but the catalogue was lost during the war.

Human soon lost a large portion of their territory. At that moment, a mysterious hero suddenly appeared on the battlefield. With a legendary Divine Weapon in hand, he severely injured Fen Tian and forced him to retreat. The united Human army chased the Demon army across the strait and to the Two Realm Plain on the Tranquil Continent.

Once again, the various forces of Human started wildly searching for the Divine Weapon Catalogue…

I wish I heard it wrong. Regrettably, I couldn’t stop Claudia.

“As long as I have Irene, I don’t need anything else.”

The three men looked at each other, then glared at me with angry eyes.

The insane obsession of The Crown Prince’s possessiveness, the smiling Duke yet something malice hid underneath him, and the cold eyes of The Knight that sent chill to my bones. It’s as if they regarded me as their rival.

“Shit. What kind of situation is this?”
