Blue Line of Defense

The disaster of meteorites swept across the earth, and alien radiation distorted everything. Human civilization retreated to high walls, with mechas as its only hope. Lin Ye comes from an ordinary family. His father is an active military pilot and his mother is a teacher. The family is stable and warm. He has no unparalleled talent, and only relies on his composure and perseverance to become a positional warrior holding a spear and carrying a huge shield. Su Wan was his childhood sweetheart, growing up together and enlisting in the army together. She is a mobile light cavalry that is as fast as the wind. She and he flank each other, relying on each other for life and death. From the protection within the high walls, to the cleanup outside the wilderness, to the future expedition into the boundless sea of ​​stars. The mecha roars, and the defense line remains forever. He protected the mountains and rivers with his shield and broke through the darkness with his gun, but the only person beside him from beginning to end was her.
