National Destiny: Delta Force's Demon Rat! One Shot, One Kill

[National Fate] + [Delta Force] + [All Kinds of Shenanigans] “National Fate battlefield?” “Dragon Country has lost ten times in a row! If this keeps up, we're about to be eliminated?” “Tsk, don't tell me it's my turn to save the day!” Xu Wen transmigrated to a world where National Fate Delta Force had arrived. Bringing memories of the top-tier veteran players from his previous life, he was astonished to find there was no leg-shot flower, no extraction-point bombing, and no rat-like knife runners. This was a world of pure combat, untainted by campers. Drawing on his memories, Xu Wen tormented the competitors from every country in this world until they were utterly miserable. AW knife runs, Victor with an extended mag for leg shots, the miracle drug M14... If you can imagine it, Xu Wen can do it. Xu Wen brought all kinds of filthy tricks into National Fate Delta Force.
