Kingdom Defense: the Long River of History

The Magic Continent under the world view of "Kingdom Defense" was initially ruled by countless dragons. However, as the ambition of the Water Dragon King continued to expand, he fired the first shot of the dragon war. Subsequently, the entire Magic Continent fell into endless war... However, after countless passages of time, what happened on the magical continent of Kingdom Defense has gradually faded out of people's sight and turned into the dust of history. Now, this historical machine will be restarted, and you will discover the truth about the entire magical continent in the past in the long history of the Kingdom Defense War... This work is a fanfic of the world-popular tower defense game "Kingdom Defense". The original game is quite good, and I highly recommend it to all my friends.
