Senior Brother, Wait a Minute! I'm a Villain!

[Two male protagonists + Nian Shang + Fantasy cultivation + Shuang Jie 1v1 + HE] Si Jiu passed through the book and transformed into the cannon fodder villain Third Brother with the same name. The system told him: Your main task is to change the fate of senior brother cannon fodder, maintain a good leisure environment, and build a beautiful home together... Sijiu looked at his senior brother, who was seriously ill, and then read the plot. He was silent for a long time. He finally embarked on a bright road - hugging his senior brother's thigh tightly. Until one day, the system suddenly told him that he had traveled to the wrong world. By the time he reacted, the system had already crashed. … Si Jiu: Why did God treat me so badly? Mu Qingxuan was able to detect his unspeakable selfishness towards his junior brother. The senior brother who is usually aloof and unapproachable fell into confusion. Si Jiu: Get close to others. Mu Qingxuan: When children grow up, they always need to make some close friends... Mu Qingxuan: Ahem... Xiaojiu, senior brother is feeling a little unwell. Everyone: Senior Brother! You need some face! Si Jiu: May I ask why you are pretending to be a sickly beauty?
