How does Ekko still have the Z-Drive in league?

If the arcane Z-Drive exploted alongside Viktor and Jayce, and it's implied that creating such device it's impossible in that reality, how does he still have it in league of legends? i just can get myself to find a way for it to be possible.

Unless we are talking about Ekkos from different universes being the ones on LOL, i don't see how could he rebuild it. For the Z-Drive to exist it required a very specific set of situations and materials that simply don't happen in the main time line, so i don't know.
