[Transmigration + System + Invisibility + Action-Packed + Killing Japanese Invaders] In 1937, Nanjing falls, and 300,000 of his fellow countrymen become victims of the Japanese invaders' blades! Li Jue, an ordinary Chinese veteran, transmigrates to Nanjing at this very moment. Just as he is about to be executed, the [God-Tier Villain System] activates! The harsher he is on the Japanese and their Chinese collaborators, the richer his rewards! From the start, he obtains [Optical Camouflage], letting him turn invisible anytime, anywhere! Looking at the arrogant Japanese lieutenant general before him, Li Jue activates his invisibility and approaches step by step, bayonet in hand. “Ding! Japanese major general eliminated. Reward: deployment map of the Japanese forces stationed in North China!” “Ding! Special High Police female section chief humiliated. Reward: mastery of every language!” He can turn invisible and get loot, too? Ha ha! Old Emperor, keep your neck clean and wait. I can come and go from your palace as I please! In this life, I'll make these Japanese invaders pay for their crimes and make up for every regret in history!
