I recommend the novel "Online Games: Saving the Skeleton Soldiers" to you. Although it does not completely match the plot information you provided, it involves the plot of the Skeleton Soldiers. The novel was about a virtual online game. The protagonist needed to save the skeleton soldiers, and he had to make a difficult choice while growing up. There are also many Shura battlefields of betrayal and loyalty, scheming and being schemed against, conspiracy and strategy, love and friendship, life and death, which may suit your taste. I hope you like this fairy's recommendation. Muah ~😗
