I Am the Commander-In-Chief in the Apocalypse of Another World

What would you do when you traveled to a country that was like the polar earth and was in the end of the world, and you happened to have a game chip? Find survivors, protect the good guys, kill the bad guys, Note: The troops owned by the protagonist have weapons, and the weapon firepower configuration will gradually increase, starting with Call of Duty 5, and gradually moving to 468 and Black Ops 7 (because the author prefers the 4 games. It will feel better to be immersive when writing). Ps: I think the writing is good. Join the group: 241716781 (total group).
