Where are the eight formations of Xunxian Dongshan Island? How to enter specifically?

You can only enter Yunmeng Mountain at level 70. The ground lock should be able to be pulled in, but nothing else will. Entry order: On Dongshan Island, there are eight major formations, in order: Qingfeng - Duanshui - Qianyue - Yirou - Star Picking - Nurturing Spirits - Zhuliu - Qianqiu (pay attention to the order, this order must be used when breaking the formation, this is the so-called ghost Valley Bafang chain formation). First, fight twenty-six "Incomplete Ghost Valley Runes" (which are found on the monsters in each formation, and each formation requires two). The other ten exchanged for a "Ghost Valley Rune" in Qiuxian Town. When breaking the formation, remember the order of the eight formations, and you must not make a mistake. It's best to complete it in one go. If you change lines in the middle, you may not succeed. After the eight formations are broken, you can enter the new map - "Yunmeng Mountain" by randomly finding one.
