Transmigrating to Kill the Japanese, Stockpiling Arms in the System Space

[Transmigration + System + Inventory Space + Ruthless] In 1937, North China has fallen. The Japanese slaughter entire cities, collaborators run rampant, and ordinary people are treated like blades of grass! The moment modern young man Chen Feng opens his eyes, he finds himself sprawled in a ruined temple full of corpses, with three Japanese soldiers pointing their guns at him! “Ding! The Iron-Blooded Resistance System has been activated. Beginner's gift pack awarded!” With a Mauser in hand and beginner-level marksmanship at his command, Chen Feng's gaze turns icy. He's no bleeding heart: he believes in repaying blood with blood! Kill Japanese soldiers to earn points and trade them for weapons and skills. Hide in the mountains, set traps, and wipe out a Japanese transit station. Disguise himself as a merchant, infiltrate a collaborator's mansion, and leave the bloody words “Collaborators must die” behind! He moves like a ghost, and every shot is a headshot. He snaps Japanese soldiers' necks in close combat and takes enemy generals' heads from a thousand meters away with god-tier marksmanship! Some call him cold-blooded, yet he uses his inventory space to stockpile medicine and food, saving displaced civilians. Others say he works alone, yet he blows up arsenals and cuts communication lines, leaving the Japanese quaking in fear! Standing amid the ruins of an occupied county town, Chen Feng looks up at the smoke-filled sky and sneers. “Anyone who dares invade China, Japanese or collaborator, won't leave here alive!” [No saintly heroine, no frustrating setbacks, and nonstop System thrills. Watch this cold-blooded transmigrator carve a bloody path through enemy-held North China all on his own!]
