In Ori and the Will of the Willpower, you can refer to the following for how to get to the last section of the Windrush Desert:
1. In the windy desert in the game, we open the map and go to the marked location.
2. After arriving at the marked location, we drilled into the sand below.
3. After drilling into the sand below, we move to the position indicated by the arrow and draw out the monsters in the purple cave.
4. After luring the monster out of the purple cave, it will run with us, and then we will return to the ground along the same path.
5. After we return to the ground, we jump to the sky.
6. After we jump to the sky, the monster will jump to the sky with us. At this time, we use the monster as a jumping point and jump to the ball in the upper right corner.
7. Jump to the ball in the upper right corner. We use the ball under our feet as a jumping point and jump to the lantern in the upper right corner.
8. After jumping to the lantern in the upper right corner, we use the lantern as a jumping point and jump to the ball above.
9. After jumping to the ball above, we use the ball under our feet as a jumping point again and jump to the lantern on the right.
10. After jumping to the lantern on the right, we use the lantern as a jumping point and jump to the platform above.
