But you are a newcomer, and it may be difficult to play for the first time.
Level 22 LR brushes the copy, unless someone with a high level takes you. If you team up to brush the copy yourself, it is unlikely, because most people are trained by doing tasks.
LR has always been the prince of solo training in WOW, and his talent combines the talent of a beastmaster. The baby helps you resist the monster, and you shoot from the side, which is very easy.
What is of great help to you now is that you go to the lower right corner of www.wowchina.com and download a Bigfoot plug-in. When doing a task, the plug-in will clearly indicate where the monster you want to kill or the person you want to find is, so that you won't run around because you are not familiar with the map.
If you really want to brush FB, you can find 70f to take you to the prison. The prison is in Stormwind, brush it to level 30, then start to brush the bloody monastery, brush it to 45, then brush STSM, you can brush it to 60, and then go to Outland, but you have to pay someone to brush FB. For a newcomer, this may be more difficult than doing a task, unless you are a RMB soldier.
Therefore, for newcomers, it is suggested to get a plug-in to do the task, so that you can be familiar with the gameplay, and it is also helpful for your future WOW career.
