The global mutation occurred, and more than 90% of all living things were mutated and demonized. At that moment, the tragedy of mankind began. Countless monsters broke through the defense lines of mankind and began to massacre. They built tall city walls. Strong walls rose from the ground to protect everyone. The high walls protected and restricted people. There were always people climbing over the mountain-like city walls.
Standing on the high wall, looking down at the endless heaven and earth, birds spread their wings and fly. The loneliest watcher looks at the freest light chaser, his eyes shine like stars, and the afterglow scattered in the world is as warm as fire.
Even if the road ahead is bumpy, never give up.
Only by standing at the top can you look into the distance.
Lu Cheng: You are free, but I have to stay here, my roots are rooted here.
Yu Yi: A bird without a harbor is not free. You will always be my harbor, and I will only stay for you.
Concept: Every free bird has its own lighthouse.
