Another World, I Was Summoned a Second Time

Western fantasy world, group portraits, complaints, invincible flow. After Li Jian became invincible, he fell into hibernation. I don't know how many years later, he was summoned to a palace. Looking at the familiar faces around him, he was shocked and speechless. All his classmates from the senior year of high school are here. "Heroes, this world needs you!" Me:? ? ? Ah? Didn't I defeat the Dragon Demon King or something like that a long time ago? How long have I slept? ... "Li Jian! Why don't you come over and squeeze my shoulders? Are you looking for death?" Huh? No, he's such a cute little gangster! ! !
