Lin En, a transmigrator, awakened the All-Class System from the start. He immediately triggered a hidden branch of the Knight class, entering Dragon Knight mode. In this otherworld, where everyone agreed one could only have a single class, he became someone with unlimited possibilities.
After one perilous adventure after another, facing life and death time and again, he gradually formed bonds with others, despite thinking of himself as an outsider merely playing at life. And all of this gradually made him realize that this world was more than a place filled with war, famine, and death. It concealed an ancient secret, and that secret was called "immortality"!
In short, this is a complex world where swords, dragons, magic, alchemy, and many other elements coexist.
