When improving combat power in World of Warcraft, many players may not know how to obtain the chemistry files for the Tortoise Server Hatred Furnace. As a newbie, I have faced similar problems and gained a lot of experience. Below is my solution to this problem, hope it helps other players.
In the quarry dungeon, after defeating the two bosses above, you have to go down and defeat the next three bosses. Go through the main entrance to defeat the boss. If you don't go through the main entrance first, go down and take the left path to the end.
