Delta Force: From the Start, I'm a Mech Brother, but I Can Change Classes Without Limit

【Open World】【Early Development】【Extended Main Story】【Early-Stage Warfare】【Late-Game Battlefield】 Streamer Jiang Chen transmigrates by chance to a parallel world of Delta Force that surpasses reality. He becomes the lowest-level AI refugee in the game world. But based on that, he is recruited by the player Leng Xiaoxing and becomes a hired 【Knife】. The Delta Force world is engulfed in war, and 【Knives】 are nothing but expendable cannon fodder on the assembly line. But Jiang Chen obtains an Unlimited Class Advancement System and possesses top-tier growth talent. He pulls out a green pair of tweezers and instantly reaches level 2, gaining +10 speed and +10 strength. He pulls out a blue stethoscope and reaches level 3, gaining +10 luck and +10 marksmanship. He pulls out a small gold item and advances directly to his second class, becoming a 【Knife Soldier】 with +10 to all attributes. Jiang Chen fights on the front lines, while a beautiful lord showers him with love and support from behind. Jiang Chen soon advances to a third-class Special Forces soldier, a fourth-class GTI operative, a fifth-class GTI captain, and a sixth-class GTI general... While everyone else is held back by their aptitude, he just keeps changing classes. As he goes on more and more adventures, Jiang Chen gradually surpasses the limits of human understanding. When the flames of war in the virtual exclusion zone spill into the human world and ignite conflict, Jiang Chen has already become the ruler of the exclusion zone, and makes a powerful entrance with the super fleet he has built!
