and then click the console in the middle of the platform. In the pop-up interface, select the top button, but not too close. It's the huge floating buildings on the map that can send the dragon in, use the ark
and then choose to upload biological data, no matter how many dragons you upload. Then you go to the ark nearest to your home. So in general, if you open the console in the same way, you can release the dragon as big as it is. You can even pass the dragon of this map to another map directly. For example, the scorched earth flying dragon can be transported to the core island or the old map, which is the ark
