In the former family residence of Princess Dan, the professor of history and Emperor Nino devoted hours to studying the literature that was given to them for inspection. The professor was surprised that Nino could read Princess Nemanjić's handwriting, because the characters had been modified significantly since the previous letter. "The basis of the letter is the same, so even though there are new characters, I can mostly understand what the princess was trying to say in the handwriting. In this book, for example, she states how the giants were of great help during the construction of a section of the border wall around Beijing, then they retreated to the island flying on dragons. "The historian looked at the book. "Nino, can I look at the book and take it in my hand? "He was wearing large prescription glasses so he could barely read the letters as Nino showed him the sentence about the giants. "That's it, the dragons fly to their flock, and where did they fly but to the Dragon's Nest, in fact the Dragon's Hole is a kind of underwater kingdom of dragons. There are a lot of lonely islands in the area, so the giants settled in, that's why they are no longer in the mountains around Beijing.""Yes, if they had stayed in the vicinity of Beijing, the Great Wall would not have collapsed and neglected some parts of the wall.We will have to move the giants again to help us rebuild the Great Wall like it used to be in the Ming Dynasty.""Of course, only if we find them.""Here, the princess wrote that many giants returned to Dalmatia, and only a few remained in the Ming Empire, they stayed to help the dragons build underwater cities, and the Dragon's Hole is the seat of the dragons, so we should look for them in the underwater mountain.""Dandan is busy at the moment, we will wait for the weekend when he has more time.Usually on the weekends he works in the rescue team, it's better to call him right now, so he will make a schedule and determine the time when he wants to drop us off by plane to the Dragon Hole.""As you say," said the professor and sent an email message to Dandan. Dandan read the message the moment it arrived, every minute during the day was filled on schedule, but he had time at night. He called the professor: "I'm free tonight to take you to the Dragon's Hole, I'll come early, or we have to wait two months when I have days off, you decide when the best time is to go. "The professor asked Nino to make a decision about the trip and Emperor Nino himself also wanted to visit the islands as soon as possible and look for the remaining giants from the Ming Dynasty. "Let's go tonight, it's better! "In that case we have to take the robot drones to build us a shelter, they are fast as you know." The professor called Dandan to ask him to page the drones to make shelters before they reached Dragon's hole by plane. "Of course, great, that's exactly what I was going to suggest, the drones will also carry food reserves and everything necessary to live on the deserted islands while you explore, in the meantime we will prepare and build a new large yacht ship that you can sail and return with the giants to one of the ports closer Beijing. Princess Dan's mansion is big enough for even giants to live in.Just kidding, if you find the Ming Dynasty giants, we will renovate the mansion and combine several rooms into one to get bigger rooms for the giants to live in.""Okay, we're going to continue our reading expedition of Princess Dan's books until you pick us up in your plane," said the professor.
