First Blood and Last Blade

The human body is a megacity with 37 trillion inhabitants. Blood vessels are highways, lymph nodes are military networks, and organs are core functional areas. T cells, B cells, DC dendritic cells - they are the city's national defense force and special police, while pathogens are invaders trying to destroy everything. Noah, the worst graduate in the history of Thymus Military Academy - T-Naive-734, a Naïve T cell judged to be "substandard". Sluggish reaction, low combat effectiveness, one step away from entering the apoptotic recycling zone. Everyone said he "had no qualifications to be a warrior." But he has what all "strong men" lose: an undecided future. When the unknown virus "EB" invades the human throat through kissing, the first line of defense is completely defeated. B-cell urban infection has fallen, and the immune system is faced with a dilemma: attacking with all its strength will destroy itself, and standing idly by will breed trouble. DC intelligence officer Tia - burdened by the shadow of her predecessor's "submission error" three years ago - has been reluctant to submit complete antigen information. Strategic genius Th-017 Helios calculated that the winning rate of all plans was less than 40%. Immunity Magistrate Arya said: "This war must stop or the immune system will kill itself." While everyone was arguing about "how to win," Noah asked another question: "If we don't fight - who will save those infected?" An initial T cell, defined as a failure, will have a difficult battle to find out who it will become. Because the weakest existence has the qualification to become everything.
