Legend of the Fire Dragon (2)

Professor Colin smiled and said, "Did you see that?" This is a real keel, not a dinosaur fossil, but the head skeleton of a real fire-breathing dragon. Why do you say that www.biquge.info pen & fun > pavilion? First of all, the composition of bones is different from the past, and it is made of a mysterious substance. Secondly dragons are homeothermic animals and usually have wings and their bones are hollow to reduce the weight of their bodies. Dragon's bones are stronger and lighter than reinforced concrete. The dragon's muscular system is the most fascinating and complex. Its bite force is on average two tons per cubic centimeter, which means that it can easily crush steel! ”

"This skull proves my point, it's very lightweight, even lighter than the bones of some birds, and proves that dragons are better at flying in the air. On land, its limbs can withstand powerful loads, while in the air it can only bear half the weight of its body. On the other hand, the dragon's entire body is covered with sword-and-shine scales, with the exception of its neck and abdomen. Perhaps, this is because it often burrows underground, but not all dragon experts agree with this opinion. To protect its fragile abdomen, dragons often wear jewel-encrusted belly armor. ”

"The skeleton was covered with swords and glowing scales that glowed blue at night. Now please turn off the lights and let everyone see what wonderful things will happen. The lights in the exhibition hall went out in an instant, and the exhibition hall immediately fell into invisible darkness. In the darkness, only a bright light source on the podium shone a brilliant blue light. The exhibition hall was filled with surprised exclamations, "Oh, that's great!" It's unbelievable! It's glowing! It's amazing, is it a real keel? It's the most mysterious thing I've ever seen in my life, oh God, is it true? I can't believe my eyes, there is such a thing in the world! It's a miracle that will shock the whole world! ”

The lights in the exhibition hall are back on, and people are filling with screams and cheers. Professor Colin had a happy smile on his face, and all of this had made his efforts not in vain. He tugged hard at the hem of his shirt, his cheeks flushing with excitement.

He raised his hand to signal everyone to be quiet, then looked down at the watch on his wrist and added, "There's even more to come!" Because the dragon's saliva is very sticky, it uses its saliva to dip gems on its neck and abdomen to protect and decorate itself. We found a huge amount of treasure in the place where the bones were found, well, that's another great find. In the treasure there are many items belonging to the ancient Middle Ages. There are gold cups studded with diamonds, as well as crowns and scepters that belong to kings. One of the most attractive is the Night Pearl, there are 500 of them! Like this skeleton, the Night Pearl has an earthy yellow surface and looks like an ordinary stone during the day, but when night falls, it emits a bright glow. What's even more amazing is that there are many dragon scales there, all of which are pentagonal, teardrop-shaped, long on both sides and short on both sides, and the shortest piece in it contains the fragrance of dragon scales. It's a very special spice that gives humans the illusion of pleasure......"

As soon as Professor Colin's words fell, the hall immediately burst into thunderous applause. Countless flashing lights flickered in the auditorium, and the intensity of the light was so intense that the professor could barely open his eyes. The professor hurriedly waved his hand and said to the audience, "Everyone, be quiet, I have made more amazing discoveries about the study of dragons." The dragon's body structure even allows it to walk upright, which is far from what we think, and it is generally believed that the dragon is similar to reptilian dinosaurs, but there is more evidence that they are two completely different species. When the dragon wants to dress itself, it can stand upright. The dragon's wings evolved from the animal's upper arms, and thus consisted of a thumb and four elongated fingers, connected by a diaphragm similar to that of a bat. The dragon's wings are not attached to the shoulders, as some biologists have depicted, but to the lower part of the back and the base of the thighs. ”

"In addition, the dragon's brain was more developed than we thought, it could think a lot, and its intelligence level was close to that of today's gorillas. The dragon's wings allow it to fly vertically upwards or horizontally, with the head and tail used to grasp the direction of flight, allowing for greater maneuverability in the air. ”

The audience nodded appreciatively as they listened to the professor's astonishing remarks, and they were particularly amazed at such a bold study.

Professor Colin stretched out three fingers and explained the classification of dragons in more detail: "Well, after my research, the colors of dragons can be roughly divided into three types, blue: from dark blue to silver to mother-of-pearl. Red: from copper to crimson to reddish-black. Green: including green, yellow, pale green, golden, and even dark brown. A dragon is usually not a single color, its scales will always have several colors in a color family, and at the same time have a metallic luster, so it is difficult to identify. ”

The professor coughed a few times and added, "If the scales become dark and opaque, then it must be sick. Dragons use fire-breathing as weapons not with some kind of magic, but with a scientific basis. When we eat, our body digests a gas called methane (CH4). Unlike humans, dragons store this gas in another lung. It is then mixed with a small amount of phosphorus (P4) and ignites when it comes into contact with air, creating a flame. Some dragons spew out frost, and the explanation for this depends on the food the dragon digests. Food enters the stomach mainly to provide nutrients, and the rest also undergoes some chemical reactions to produce a gas called nitrogen (N2). Nitrogen is naturally compressed in the lungs, and when the dragon wants to freeze an object, the nitrogen that is compressed into a liquid state is released into the air in the lungs, and then quickly decompressed, absorbing a lot of heat in the environment, which makes the gas in its breath drop to about minus 50 degrees, and ordinary animals are attacked by this, and they can be seriously injured or killed! ”

The professor's explanation gave everyone a new understanding of the dragon as a creature, and they fell on the professor with admiration. The reporters in the audience kept their heads down and kept writing, talking to each other from time to time, gesticulating, and expounding each other's views and opinions. What excites journalists the most is that the news sounds particularly novel, and judging by their keen sense of smell for a long time in journalism, these novel statements are 'explosive news'.

Professor Colin had a mysterious smile on his face, he clenched his fists, and said to everyone: "Creatures have acid in their stomachs to help digest food, and dragons that can spew acid have special organs that produce powerful acid, and when the dragon exhales, the prey will be injured by the acid, even the best shields will not help." The reproductive system of the dragon is in the body, and it is impossible to determine whether a dragon is male or female only when observed from the outside. Dragons lay eggs like reptiles and birds, and the eggshells start to be very hard and then slowly soften, and the baby dragons break out of their shells. ”

"It's worth mentioning that the mating process of the dragons is interesting, the two dragons are hovering and flying together in the sky, and suddenly, they reach out their claws and grab each other, then retract their wings and start a freefall movement, and when they are still a hundred feet above the ground, they spread their wings and land. Dragons are a species that loves speed and adventure, so the mating process is also full of this fun. Dragons have long been solitary, and there are not many of them. Personally, I think dragons are lovers of performance art, especially gold, silver, and handicrafts, so they often store treasures to show off to the opposite sex. ”

Professor Colin paused, smiled, and said, "It's a big secret that anyone who discovers its nest will make a big fortune!" In the limited time I have today, I will try to tell you all the research results on dragons. ”

"Because the dragon doesn't like to do manual work on its own, it has to do everything it can to get from humans. Fearing the loss of its treasures, it always hides in its storeroom and guards them. It had a detailed list of all the treasures in its mind, and if it lost a jewel or two, it would immediately notice. Because jewelry means so much to the dragon, it often sleeps on a bed of silk and velvet covered with precious stones, and it never uses softer stones like pearls and emeralds because they are so fragile!
