Bandit: From the Start, I Have a Mountain, and Must Snatch Every Wife

(Shameless and devious + decisive and ruthless + villainous warlord + base-building + beautiful legs) Sima Hong transmigrates into another world and becomes the chief of Evil Tiger Stronghold. Betrayed by his wife and brothers, with morale collapsing within the stronghold and the granary nearly empty, his situation is a disaster from the start! Fortunately, his golden finger is linked to a nation, allowing him to trade between two worlds. “What? Too many people and not enough food? Don’t panic! I have The Complete Guide to Scientific Farming!” “What? The troops are coming to suppress the bandits? Don’t be afraid. Form up, and get the guns and cannons ready!” “What? Evil spirits are invading? Don’t worry! I’ll banish them with science! Wait... that can’t be right! Isn’t this a low-martial world? Where did all these monsters and demons come from?!!!”
