After Entering the Infinite Flow, I Became a Human Shield

【Two Male Leads + Infinite Flow + False Transmigration into a Book + Choose One of Multiple Love Interests】 Shi Yan transmigrates into a book, and the System gives him a mission: keep the entire protagonist group alive. What a simple task. All he has to do is keep the whole protagonist group, who are supposed to be wiped out, alive. Can he still save himself if he gets down on his knees now? Who could have guessed that things would take a turn, and Shi Yan would catch the eye of Jian Hui, a dungeon boss? Shi Yan: “Don’t come any closer. I’ll die.” Boss: “How could you die, brother? If you have to die, why not die in my arms?” Fu Chen, the original protagonist, realized early on that something was off about Shi Yan and bound him to his side. “I don’t know what your motive is, but I’ll keep a close eye on everything you do.” Shi Yan: “System, my childhood friend says he wants me home for dinner. Let me go home, please.” Xia Youshi: “But I’m right here.” Shi Yan: “...Huh?” Xia Youshi: “Welcome home.” After being followed on the street, Shi Yan grabs the stalker, ready to teach him a lesson. But the other guy plays the victim. Mo Ji: “You look like my captain from when I was alive. I miss him so much.” Shi Yan: An apparently immortal transmigrator, but actually the game’s core data and the bottom. Xia Youshi: A gentle, considerate childhood friend on the surface, but actually an obsessive, possessive, unhinged game god and the top. Jian Hui: A seemingly deranged dungeon-roaming boss with extreme possessiveness, but actually a lonely top who treats people politely. Fu Chen: Cool on the outside, warm on the inside, a loyal and dependable daddy-type top. Mo Ji: Seems unremarkable, but is actually a powerful and mysterious top.
