The rulers of the various planes and their brains gradually discovered the pattern as the number of golden fruits dropped increased.
Firstly, the tree that bore the golden fruit did not seem to exist in this plane. The soldiers could not find any traces of it, no matter how they searched.
Secondly, as the number of soldiers killed increased, the ripeness of the golden fruits would enormously increase.
From this, one could infer that those golden fruits matured when they absorbed flesh and blood.
Perhaps the swamp of flesh and blood under their feet was the main body that nurtured the golden fruit. The giant tree devoured its energy through some invisible spatial rifts.
That could also explain why the swamp swallowed the dead soldiers on the battlefield.
Several soldiers had died. They must have all become nutrients for the golden fruit now.
