I Asked You to Temporarily Take Charge of the Guild, and You Turned into a Goblin Empire?

Lu Chen traveled through the world of Fairy Tail and became a member of Fairy Tail. I wanted to leisurely pick up girls and enjoy life. Who would have thought that President Makarov would give him a hard job. The association will be managed for one year. It happened that Lu Chen accidentally awakened the development system. As long as the strength of his guild members improves, can it be fed back to him? Lu Chen decisively agreed. Half a year later, Makarov, who was on vacation, accidentally heard that Natsu had become an S-class mage? Then I heard that Kana could summon the blue-eyed white dragon? And Erza's costume change can actually be solved? He even heard that Lucy became a Saint? Even Hapi has become a saint? Makarov, sensing something was wrong, rushed back to the guild overnight. But he was so horrified that he couldn't close his mouth from ear to ear. Who can tell me what is going on with this fairy empire that spans the entire continent? Lu Chen: That's unfair, I just want to develop the guild. I don't know who put the crown on me while I was sleeping. Wearing a crown, I have to accept this call from your majesty!
