Epoch

An epoch was a unit of time from the ancient era. One epoch was ten million years.
In that era, there had been a kind of tree called the Epoch Pine Tree. Every thousand years, it would grow a pine cone, and when there were ten thousand pine cones, the Epoch Pine Tree would immediately wither to death.
But ten million years later, the Epoch Pine Tree would be reborn. Its life and death was precisely twenty million years. That was how the Epoch Pine Tree's lifespan had become a simple and clear measurement of time in the ancient era.
However, as a unit of measurement, the epoch was no longer used in the current world. It was simply too long a time.
