I Am in Modern Times, but I Have Obtained the Ancestral Anti-War System

Fang Le's great-grandfather Fang Nanshan was a glorious Eighth Route Army soldier who died in the Anti-Japanese War. 80 Years after the end of the Anti-Japanese War, Fang Le and his father went to the Martyrs Cemetery to visit his great-grandfather's grave. He originally thought that the glorious and heroic deeds of his great-grandfather who had been hearing cocoons since he was a child were all exaggerated or even false. Who would have thought that the reason why my great-grandfather was able to achieve those invincible feats was because he activated a system to fight against Japanese invaders. The "ghost" of the great-great-grandfather appeared in the martyrs' cemetery and wanted to hand over this "ancestral" anti-Japanese war system to his great-grandson and continue to complete the cause of fighting the Japanese. The problem is, now that we are in peaceful times, where can we go to fight the Japanese? Grandpa, aren't you making things difficult for me, your great-grandson? —— Once the east wind comes to Pingwo Island, 35 million people will pay tribute! —— PS: Invincible flow of great powers fighting for hegemony with sci-fi elements to clean up the small days This novel and its characters are purely fictitious.
