In her previous life, Yun Chujiu was the Empire's chief 3D illusion architect. By a twist of fate, her consciousness is forcibly loaded into the dying body of the Yun family's true heiress, who had been cast out and left to perish. The moment she opens her eyes, she faces not only a system survival countdown nearing zero but also deadly, mutated phantoms lurking in an abandoned puppet-mech pit. To prevent a system crash and keep herself alive, she instinctively rewrites the monsters' underlying logic with one hand, then forcefully siphons the overflowing high-energy source qi from Huo Chenyuan, the God of War and Regent, to make a full recovery. Huo Chenyuan commands a formidable army but suffers from severe source-qi overload contamination, making him, in Yun Chujiu's eyes, the perfect high-end, mobile computing-power reservoir.
