Where is Pokemon's dark phantom "The Last Slate (Reading Unknown Symbols)"?

First, LZ will catch a whale king and a map fish. Wailord can sink a whale and evolve. Map fish should have a chance to dive.

Catch the whale king first and the map fish last. Then surf to the 104 waterway, and there is a small diving place (this is hard to find, because the place is small, and there is water everywhere, which accidentally floats past. It is suggested that LZ go to the lowest place in Shui Mu Town and drift slowly to the middle).

Then dive down, go to the place on the map you sent and read the words on the wall. After reading it, I dug a hole and it was an earthquake (obtained at Fossil Fanjia in Dongxue Town). . . Then you can go in and see the king of pillars. . . ) In this way, all the holes in the three pillars were opened.

Shen Yan Shizhu Cave is deep in the desert. After entering the cave, read the text, then take two steps to the left and two steps down. The cave is opened, and there is Shen Yan No.40 stone pillar.

The hole of Iceberg Column is located in the waterway of 105. After entering the hole, read the text, walk clockwise against the wall (remember to stick the wall) and the hole will open. The ice pillar is in level 40.

The hole in the steel column is on the 120 road (that is, where it has been raining and grass is everywhere). Carefully find an uphill slope, read the text after entering the hole, and then walk to the middle of the hole by flashing, and the hole will be opened with a 40-level steel column.

After catching the three pillars, you can go back to the cave of Shuilu 104 to catch the pillar king.

I hope I can help LZ. I am tired of playing with my hands. I hope to adopt.
