The Viscount of Lane, isolated by thick fog, faced countless monster sieges. A young knight attendant was seriously injured in his first encounter with a demon. He woke up after three days in a coma. These three days of coma became the starting point for the little attendant to become a glorious hero, because no one knew that his heart had disappeared from his chest and was replaced by a majestic and majestic castle!
Holding the main city of mankind in hand, establishing glorious achievements, darkness covers the world, and the heart of the castle is immortal!
