It is really difficult to do this task. I don't want to do it after playing a few tasks. I run all over the mountain, and the map is big and white. Later, I checked online, bought some G's, and began to let others take the brushes.

You are now 14. Go to the death mine first and brush it to 15. Someone will take you to 15 for free after the full shout. The death mine is located in the reed hut in Yuexi Town, the lower left corner of the western wilderness. I guess you will find it difficult to find the entrance. Then kill the monster to 15 first, and then brush it to 20 in Stormwind prison, which is also free. You can know the location by Baidu yourself. Flower G is brushed to 40, then black to 65, and then brushed to full level 70 in Outland. After 20, you will have to charge a brush fee, which is about 2 cards. Convenient and quick. I brush a few of these numbers.
