Wulin Gaiden New Professional Guitar Mission

Go to Shopkeeper Tong from 7 Heroes to pick up the 2 missions. Once the following missions are completed, continue until you can no longer pick up the missions. Then go to Southern Xinjiang to fly 2 travel coupons. Finally, go to the capital to find Mai to pick up the missions. Follow the prompts for the task and go to the Southern Xinjiang FB. Defeat 99 monsters and give the dropped items to the designated FB NPC to complete. It seems that you have to form a team yourself or bring it with you.
