Actually, how can I put it? This is still a small unknown. Although technology looks very advanced now, it is still a mystery to really see what is inside the earth, because no one has really witnessed what the deepest part of the ocean looks like, and most of the detectors are ultrasonic, so it is difficult to see what is in the deepest part of the ocean even if it is photographed, but the dragon is regarded as a god beast by us, or it may be because the ancients have hallucinations due to environmental factors, or some large lizards or surviving dinosaurs. Because the ancients didn't see it often, they only gave a vague answer. And is there a dragon in the world today? Why do they never show up? It is up to people like you who are curious and interested in it to discover and visit.
