In AD 3044, civilization collapsed and the world became a wasteland. The survivors huddled in four categories: the terror of the restricted area, the chaos of the war-torn area, the despair of the slum area, and the cruelty of the paradise area.
Young Chen Xingran struggled to survive in the garbage dump just to protect his sick sister. During a desperate escape, his blood dyed a decaying mecha named "Desolate Bone" red, thus awakening the ancient Xuanjia Sect inheritance - the Shanhe Sheji Tu system. Using the fire of karma as fuel and fighting as merit, his mecha has unlimited evolution possibilities!
However, power is also a curse. The pursuit of Tianshu Pavilion, the greed of the Earth Demon Alliance, and the whispers of the Netherworld Group followed one after another. On this bloody journey, he is not alone: the calm and wise mechanic Su Siye and her "Qingluan", the defender as reliable as the mountain Shi Shoushan and his "Black Turtle"... Partners with destiny and ability, gathered by faith and bond.
When the seven "stars" finally return to their positions, what they face is the old enemy "Eclipse" who also possesses seven terrifying mechas. It is a conspiracy that can overturn the world, and the ultimate truth about the fall of the ancient mecha civilization...
