1. You need to find two objects: the Snake God's Head - Panzhu Beads and the Snake God's Head - Panzhu Stone. These two objects are respectively in the two red circle places on the map. To find them through the elemental vision, first go to the red circle place on the left to get the beads.
2. When you enter the map, you will find that there are 7 light-emitting mechanisms that need to be adjusted in the following order. Adjust the angles of No. 1 to the middle, No. 2 and No. 3 to the middle of the elevation, No. 4 to the bottom, and No. 5, No. 6, and No. 7 all to the middle.
3. Then shoot the No. 1 mechanism and it will go through each mechanism sequentially like a pinball to break the water cover in the middle. You can see a purple bead in the middle. This is the head of the snake god, the Panzhu Bead. Just pick it up.
4. Go to the next location to find objects. Enter the map and go to the cave entrance to get a thunder seed.
5. Then just jump into the cave and activate the stone tablet to kill monsters.
6. After defeating the monsters, go to the three purple stone tablets and hit them twice in the middle and twice on the right to make them look like the three in the picture.
7. Continue to jump down and beat the slimes. If you go inside, you will see a purple rock. Just pick it up.
8. Then summon the two Thunder Seeds next to you to jump out and deliver the Snake God's Head·Pan Pillar Bead and the Snake God's Head·Pan Pillar Stone. This mission is over.
