The Lord of Elements from a Drop of Water

"Upon waking up one day, Ren found that he had travelled to another world and become a novice water elemental.
He discovered that as long as he continued to consume elemental energy, he could evolve limitlessly!
From a water elemental to the Lord of Elements; his name was praised by countless lifeforms!
Some called him the “Master of Elements”, since he commanded all the elementals of the world. As long as he desired, he could vanquish all the elementals.
Some called him the “God of Water”. All the rivers, lakes and oceans of the world were his territory!
Some called him the “Apocalypse of the World”; his godly strength spread far and wide; it could vanquish all the heavens and earth, and uncountable elemental planes!"
