Broken Age

At the age of eight, Lordonk disappeared. What replaced it was a red fragment 200 kilometers in diameter, driving like a wedge into the flesh of the earth. Twelve years later, New Lordunk was built on the edge of the ruins, and more than 20,000 armed men surrounded the entire city within their sight. More than four hundred fragments are floating in the offshore sea, fourteen red fragments are scattered across the continent of Eria, and there is a red that no one can reach in the deepest part. Chen is the only person who came out of the center of the zero fragment. He has no past, no name, only the word "dust" and the code name "Phantom". He walked into that red sky every day, came back alive, and then waited for the next time he entered. He thought he was just on a mission. Until he realized that the sound he heard came from farther away.
