The First Spinjitzu Master probably did have semi-immortallity. He was the first being in Ninjago, and created an entire world. I don't know of anything that could've killed him.

As for Wu and Garmadon, Wu only has the element of Creation, and Garmadon didn't even have an element. It's still possible that longevity just runs in their family, and they may not die at the average age of death.

Still, in Spinjitzu Prodigies, I would not have Wu alive anymore. It's taking his age a little too far.
