Review Detail of Danteuros in Transmigration to Another World

So becoming king of beggars. Can't u make the mc smart enough to cultivate stealth type devil body to steal some cash from wallets or any other place with his supernatural abilities and use local thugs and gangsters as training dummies before seeking out near obvious supernatural encounters. Learn to use abilities to scout out stray devils, choose the weakest, kill it and get enough points to buy something to help him or get out of the situation( like hypnosis magic and observation haki). As for shelter he can use abandoned warehouses, rob the local gangs with his enhanced physique.
