The War of Resistance: from Nanyang Warlords to His Majesty the King

[Anti-Japanese War + Nanyang Founding + System + Infrastructure + Multiple Female Protagonists + Arms Race] Good news, I traveled through time and became a descendant of the royal family of the Nanyang Kingdom in the parallel world. Bad news, powerless, family fortune is in ruins! It's 1935, and the war is about to break out! As a descendant of the Nanyang royal family, there are thieves stealing the country, so you should help the country! Powerless? What to be afraid of! I have a super warlord system! Strategic map, the exploration distance is 500 miles, all resources and enemies are invisible! Skill entries, precise shooting, three-three tactics, jungle combat, self-taught without a teacher! Industrial entries are advancing by leaps and bounds, flourishing, ingenious workmanship, and getting twice the result with half the effort! Agricultural terms: bumper crops, prosperous livestock, good weather, and fertile fields! From being a small town police officer, to fighting all the way to the north and south, farming and developing, and looking back now, he is now His Majesty the King!
