What's so hard about Neptune? From the east-west pile to the three-eye corridor, take the entrance in the upper right corner and go straight; There is a place (belonging to pets) in the middle, probably a Beibei pile or a strong pile. There are two roads, 1 (sea 1) under the haystack and 1 (sea 3) around the haystack, from the haystack (malt can also pass through the shadow heap to the haystack) to the hard shell heap, and there is a hard way to go down to Neptune.
