Douban: the Soul Penetrates the Spirit Behind and Possesses Xiao Yan at the Beginning

Xiao Xi accidentally traveled to the world of Dou Po Cang Qiong in the form of a spirit behind him, only to find that this world seemed different from the Dou Qi Continent he was familiar with... As a last resort, Xiao Xi had to use the system to start simulations again and again, and use this to change everyone's lives. If Nalan Yanran didn't break off the engagement openly, if Cai Lin didn't need to forcibly evolve, if Xiao Yan was a woman... Wait, this last one doesn't seem to be what if! Who are you? Where is Xiao Yan? What, you said your name is Xiao Yan? Is this fighting world really a serious world?
