Game of Thrones, I Use the Alchemy Dragon to Shine on Ice and Fire

When Rex woke up, he found that he had traveled to the continent of Westeros in "Game of Thrones". The timeline was a relatively peaceful period ruled by Robert Baratheon. Before he had time to adapt to this world where swords and conspiracy coexist, a mysterious "Hermes Alchemist's Manual" appeared in his mind out of thin air. The first page of the manual clearly records the refining method of the ultimate alchemical creation - the living puppet dragon. However, the rarity of dragon bones, the expense of Valyrian steel, and the danger of sacrificing the heart alive make this ultimate goal out of reach. Fortunately, he was not without options. The content at the back of the manual is relatively friendly: puppet guard dogs, gargoyles, alchemical ravens... Each creature has a unique ability, and the difficulty of refining has gradually dropped from "hell level" to "can be obtained with hard work." In a remote stone house on the outskirts of Highgarden, Rex used a fierce dog he hunted by himself, thirteen iron nails forged by himself, and a strange combination of mercury and sulfur to successfully refine his first alchemy creation, the "Underworld Mastiff." This sleepless, fearless puppet dog became his most reliable partner in this strange world. But good luck will not always be with you. The continuous failures in refining gargoyles made Rex soberly aware that the success of the Underworld Mastiff might have just used up all his novice luck. If you want to gain a foothold in this world, just relying on a watchdog is not enough.
