When I Run Out of Ammunition and Food, I Rely on Part-Time Work to Support the Entire Army!

[Travel flow] + [Two Worlds] + [Shuangwen] + [Business War and Military] When Lin Feng, the Great Flame God of War, ran out of ammunition and food at Tiger Ya Pass, his family heirloom jade pendant was activated, accidentally opening the door to travel between ancient and modern times. On one side, there are three thousand remnants of the army defending the isolated city, facing the desperate situation of one hundred thousand barbarian cavalry; on the other side, there is the modern city of the steel jungle, hiding endless technology and resources. The meat buns he exchanged for hundred-dollar bills became a "miracle" in the eyes of the soldiers. The Mo Dao made of modern special steel was invincible on the battlefield, and he used compound crossbows and gasoline to burn enemy catapult positions. When ancient martial arts meet the power of modern firearms, and when the battlefield killer breaks into the undercurrent of the business empire, this man holding a jade pendant is destined to make huge waves in both worlds. So what if there are 100,000 enemy troops? As long as he can travel between the two worlds, the entire modern civilization will be his arsenal! But when his secrets are gradually exposed, the Su family consortium, underground forces, and hidden families all turn their attention to this mysterious man... How far can he go in the two worlds?
