Lin Xueji, a novice gamer, fell asleep after another disastrous defeat in the "Delta" ranking match. When he woke up, he found that he had not exited the game, but was wearing a tattered knight's armor, holding a rusty spear, and was in the ruins of a real battlefield. His game ID "Tang Ji Ke De" became his real name, and his mind was quietly infected by "chivalry". Since then, there has been an absurd knight on the modern battlefield who charges at the machine gun tower, treats armored vehicles as behemoths, and treats supply bags as sacred objects. This is a rookie war epic full of faith (or delusion).
