I Am the System, Host, Please Work for Me

Wang Dao: "I only have two purposes here, to earn resources, or to earn resources by ****!" Wang Dao has obtained a mysterious sandbox, which allows him to travel through various worlds, pretending to be a system and issuing tasks to travelers in various worlds, in exchange for the resources he needs to cultivate immortality. Use this to improve your own cultivation! Other casual cultivators: "No, buddy, isn't this world of immortality extinct long ago? Why do you use it as food!?" Sect disciple: "Excellent Qi and Blood product? It seems that Senior Brother Wang's alchemy skills have improved again." People couldn't help but fall into deep thought when they looked at the king who had risen from Qi refining to foundation building in just one month.
