After I Was Discharged from the Army and Went to College, the Instructor Was Actually My Soldier

Lu Xingye, the young chief instructor of Xia Kingdom's most mysterious special forces, codenamed Tyrant! Due to his long-term execution of hell-level missions, his body was on the verge of reaching its limit, and he was forced to retire by the military. He disguised himself as an ordinary freshman to cultivate his body and mind. I thought I could experience college life in a safe way, but when the military training started, I met Xiao Rui, the devil chief instructor who is known as the most ferocious in the military region. In order to establish his authority, Xiao Rui randomly selected a new student to stand out, preparing to give him a severe blow. But when he saw the half-smiling face in front of him, the tough guy's scalp instantly went numb and his legs became weak. Because the freshman in front of him was the old leader who pushed him in the quagmire and beat him wildly, and single-handedly trained him to become a military king! Under the shocked gazes of all the teachers and students in the school, the devil instructor not only did not punish the assassin, but instead stood at attention with a snap and saluted an extremely standard military salute in public. The whole school was in shock, and everyone was speculating on the terrifying background of this new student. From then on, Lu Xingye's leisurely college life completely went astray. The school beauties were constantly testing him, the rich second generation was provoking wildly, and the evil forces outside the school came to visit him at all costs. Until one day, top foreign mercenaries lurked in Donghai City, and the local armed forces were helpless. Ten armed helicopters landed on the university playground. Several military leaders carrying Venus were sweating profusely and bent down in front of the entire school. "Chief, the country needs you, please come out!"
