Reinhardt, a former investment banker elite, once a plane crashed, his soul passed through the second son of the fallen earl of the continent of Iseland - the territory surrounded by his family, his brother who was linked to the orcs, and the covetous Federation, it was a dead end from the beginning.
Without a system or modern technology, he used a leather notebook engraved with economic formulas to play medieval tactics: using a "debt trap" to swallow up the property of neighboring nobles, using a "war of public opinion" to tear through the hypocritical mask of the Holy See, relying on a "blood magic contract" to tie the lifeblood of powerful ministers, and forcibly taking the ruins of the Blood Thorn to build a war fortress that everyone was afraid of.
He is a master of swordsmanship and decisive in killing - he cut off the traitor brother's right hand at the family meeting, burned the heretic list in the court of justice, and rode a bone dragon to defend the royal capital to defeat the enemy, but he prefers to talk dirty to the harem:
Laughing at the poisonous kiss of the dark elf assassin Vivian: "Your venom is worse than the love words of your mistress";
While stabilizing the magic power of Storm Mage Freya, he joked: "This 'magic blend' is more exciting than the mergers and acquisitions I did back then";
Catching the knight's spear from Knight Commander Charlotte: "If you exchange your life for me, then I will have to spend the rest of my life 'repaying the debt'."
The cracks in the void are filled with aberrant creatures, and the three kingdoms are busy fighting. Reinhardt is sitting on a throne wrapped with bloodthorn vines. While watching the harvest of the wheat fields in the territory, he pinches the Elf Queen's waist with a hidden dagger: "Want to kill me? First, accompany me to draw the territory of the Bloodthorn Territory to the end of the continent."
