History is the last dragon in Middle-earth. It is described as reddish and golden, and it is huge. Like other dragons, Shi can breathe fire, but Shi is more dangerous than other dragons: he has a powerful hammer on his tail. Stone's abdomen was covered with jewels, which made him almost unhurt, but Bilbo found that Stone's left breast was unprotected in the stone's nest, so Bilbo told the dwarf about this weakness, and the crow living in the secret door of the lonely mountain also heard the news and told Bud in the valley town. Later, Shi attacked the valley town, and Bud shot a black arrow at Shi's left chest, killing Shi. Therefore, it is not the whole body armor shown in the movie, but a scale is missing from the left chest!
