How Did a Disabled Veteran Like You Become a Devil Instructor?

[Special forces + Fire Phoenix + transmigration + System + spin-off] Xiao Bing transmigrates to a parallel world and resolutely trades his pen for a gun, dedicating himself to his country! Through sheer perseverance, he becomes an honored special forces soldier. But along with all his honors, he is covered in scars, his body on the verge of collapse. Faced with his former superior’s desperate pleas and his comrades’ reluctance to let him go, a soldier’s pride and dignity lead Xiao Bing to prepare to return home after leaving the military. Then the System awakens. As long as he becomes the chief instructor, his body will recover, and he’ll grow stronger too. A female soldier instructor? Not on your life... If nobody else wants the job, I’ll take it! Thunder God: “They’re parachuting in a chief instructor? I won’t... I have the utmost respect for Xiao Bing.” Ye Cunxin: “The chief instructor is the coolest and strongest!” Fire Phoenix: “How can a sickly guy be our chief instructor? Ah... he’s incredible!”
