This is translated by AI, I don't know if you can understand it.
After starting the game, I placed the shaft elevator in my backpack and descended. Then, I pressed CTRL+E to teleport to the surface. When I returned to the initial base, I excavated the shaft elevator and ascended. After entering the surface again through the shaft elevator, I returned to the base and created a new shaft elevator to ascend. Thus, I had infinitely many ascents.
