When a Brave Man Is a Wise P Club Player

"Great brave men, we summon you from another world to defeat the devil and the invaders and save us from the fire and water. Come out! Five brave men!" But these poor alien natives don't know that one of the five brave men is more evil than the Demon King! Who is he? He is a staunch supporter of medieval medicine, a map painter, a cannery factory owner, the most loyal legionnaire of the Ming Dynasty, a friend of Rome, a player of P Club, Zhang Kan, who punches the Pope and kicks the fallen empire. He regards human life as a number and national borders as nothing. A crazy adventure story of a snake man. See how he saves another world by training Lin Dengwan, marrying his daughter at a strategic level, improving the economy with endless toll booths, and other trivial things! (A funny novel, don't take it too seriously, the protagonist is crazy)
