The Villain of the Two Worlds: from Modern Times to the Late Ming Dynasty

I accidentally obtained King Mu's Seal, and I was able to travel freely between modern times and the late Ming Dynasty! While others were suffering from hunger and cold, fleeing famine and waiting to die, I used modern food and salt to sweep through the troubled times, and returned with ancient paintings and national treasures to become rich. Fight against profiteers, rescue beauties in distress, build private armies, eliminate traitors, reform bad governance, sweep away Tartars, and stabilize the world. Modern materials on the left hand, time and space treasures on the right hand... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
