The brave fight the dragon 7. Where is the magic key?

The brave man met Kerry and Bly at the hotel in Map Town. Kerry is sick in bed and needs Dipach's roots to continue his life. Bly joined in. Go to the farming city on the lower right of the map, and the king of the city will plow the fields himself, but all the crops are dead because of the drought. Fortunately, the king refrigerated a spare Dipach seed in an ice cave at the southern tip of the mainland. The brave enter the cave to get comfortable robes, speed seeds and magic seeds, which are recommended to dancers. The treasure chest at the bottom of the cave is a trap. Do not open it. The treasure chest in the middle is Tipachi seed. Take the seeds to the king who is farming, grow into Dipach's roots in an instant, feed them to Kerry, and the three of them will surrender with the thief's keys and sell the extra items by the way. At this point, it is suggested that the brave, dancers, businessmen and princesses should be the main force. The princess can't wear a shield. It is recommended to wear a dancer's comfortable robe and a fortune teller's golden hair accessory. At this time, the first chapter helps lion's jellyfish evolve into human form after years of cultivation. It tells the brave that the lion went to the darkroom city in the southwest of the map. The dog hole in darkroom city is locked by the magic door. Sisters suggest going to the alchemy cave to see if the senior brother left the magic key. Sure enough, there is a button in the treasure chest next to the pond in the cave. Press out a basement and open the door with the thief's key to get the magic key.
