Li Mo, a genius FPS e-sports player, is transported to the battlefield of Shanghai as a new recruit and activates the [Gun God Sign-in System]. Upon signing in, he immediately gains [Firearms Proficiency (Max Level)] and [Bullet Time]! With any weapon at his disposal, he instantly becomes one with the gun, hitting his target every time! Facing the surging tide of Japanese soldiers, he wields a Chiang Kai-shek rifle, activates "Bullet Time," and from 150 meters away, every shot is a headshot, single-handedly repelling an entire Japanese company's attack! The regimental commander exclaims, "Where did this sharpshooter come from?" "Reporting to the regimental commander, Li Mo predicted the trajectory of the Japanese grenade launcher and blew it up in mid-air!" "Reporting to the division commander, Li Mo infiltrated alone and wiped out an entire Japanese artillery position with a Mauser pistol!" "Reporting to the corps commander, the Japanese sent out a sniper, but Li Mo swept him away with machine gun fire from 800 meters away!" From then on, a ghostly legend arose on the battlefield. He was the "White Death," capable of taking the enemy general's head amidst a sea of soldiers; the "Battlefield Ghost," able to bring down an airplane with a grenade. The Japanese set a "kill order" for him, offering a bounty of 100,000 silver dollars, yet they couldn't even catch a glimpse of him!
