There are many versions of the legends about the Coffin of Deathly Silence and the Populus Euphratica Divine Tree across the entire Wildland Continent.
Some say that after a heaven‑shaking strong one died, his corpse transformed into the Coffin of Deathly Silence, and he drew out all the vitality of that deathly land and condensed it into this Populus Euphratica Divine Tree, hoping to use it to be reborn.
Others say the Wildland Continent was originally the back garden of a Super Expert, and the Populus Euphratica Divine Tree was planted by that strong one and will be taken away by him someday.
However, no matter which version of the legend, none can specifically spell out its era.
Because the Coffin of Deathly Silence and that Populus Euphratica Divine Tree seem to have existed even before the history of all living beings.
