In a future torn apart by the "Galaxy Exhaustion" war, human civilization is struggling on the edge of despair. Mecha Warrior Ling Xiao, an ace pilot codenamed "Shadow Blade", was completely surrounded by the enemy's steel torrent during a desperate raid. His mecha was in dilapidated condition, its energy was on the verge of exhaustion, and the shadow of death hung over him. However, at this critical moment, an unprecedented torrent of energy suddenly poured into the depths of his consciousness. Ling Xiao suddenly awakened. Not only did he gain the terrifying ability to control the passage of local time, but he was also accompanied by broken memories that emerged in his mind - fragments of an ancient civilization that should not exist, and a mysterious and quiet voice claiming to trace the moon.
Su Yue, an outstanding scientist from the forgotten timeline, her consciousness is bound to Ling Xiao's awakening in some way. Through her guidance, Ling Xiao was shocked to discover that the "exhaustion of the galaxy" was not a simple competition for resources, but a deeper space-time anomaly that threatened the existence of the entire universe. The ability he awakened is the key to resisting this cosmic disaster. Ling Xiao is not just a mecha pilot, he has become a "time-reversing armor", the last hope of human civilization in the vast galaxy.
But every time he interferes with time, there are unpredictable consequences. In dealing with the enemy, exploring the secrets of ancient civilizations, and harnessing his own power, Ling Xiao must move forward carefully on the blurred line between salvation and destruction. Can he reveal the truth behind the "depletion of the galaxy" and bring the galaxy back to life? What kind of unknown secrets does Suyue, this messenger from the past, hide?
