I Was in the Special Forces Pretending to Be a Pig and Eating the Tiger.

Lin Xiao never thought that he would transform from a special forces instructor to a cannon fodder character in a TV series. In this crisis-ridden modern city, foreign spies, underground black markets and corrupt forces are intertwined, and he can only rely on a mysterious chip to survive in the secret army. As a time traveler, he is well aware of the direction of the plot, but cannot prevent the sacrifice of his teammates; he longs to return to reality, but is involved in life and death missions. The gentleness of military doctor Su Qinghe made him let down his guard, the trust of commander Zhou Zhengyang made him feel tormented, and Chen Feng's hostility was like a sharp knife hanging from his head. The ability brought by each sign-in is like a double-edged sword, which helps him rise step by step but also makes him fall into a deeper vortex. When the truth is revealed, he must choose between saving the one he loves or changing his destiny.
