Thirteen young men shouldered the mission of guardianship and went to the interstellar battlefield to fight against the invasion of alien groups. They used the stars as evidence, the sharp blade as an oath, and used their youth and blood to build a solid defense line for the earth. Some turned into stardust, while others held on until the last moment. When peace is restored in their hometown, their stories will be remembered forever, and the heroic souls watch in the deep space and become the eternal light in legend.
