MTL - My Backyard is the Tang Dynasty - ~ push!

I possessed the weakest character in a survival game. Before the game started, 97% of the viewers bet that I would die. But I am confident. Because I am here, this character will survive until the end. I know the information about this survival game. *** After working hard, I became the guild master of the No. 1 guild and one of the top rankers. I gained reliable comrades and allies. “Rudel, you’re a really good person.” Lilith, the beautiful female character who always trusts me unconditionally. “Let’s eat that deer.” Gio, the battle member who, despite being half-naked and always hungry, holds immense potential. All I did was strive to survive. But some wanted more from me. “If you don’t have anyone else in mind… you could accept me.” The No. 1 male character in appearance clings to me, nearly in tears. The hidden character and the only bug character in this game that I found- “Rudel, you are dazzling. Both in body and soul. Unlike me.” He looked at me with clear eyes as if I were the only person in the world. Everyone, please stop. I’m busy uncovering the secrets of this game.

A novel revolving around being transported to another world with an op system. The mc spends his day chasing skirts and doing missions to level up. A standard journey to the top with lots of girls from various animes and games with a twist of that gaming feel (hunting mobs, doing missions).
