Forty-two millennia later, the entire empire is caught in an endless war. The human empire tries its best to maintain its rule, while facing the fierce invasion of alien races, the secret sabotage of chaos sects, and internal corruption and power struggles. The former AI forces (Iron Man) were almost completely wiped out in past wars, but as an intelligent commanding Iron Man that was accidentally activated, Axe is inevitably involved in the entanglement of various forces.

As a time traveler transported to the Warhammer 40k universe carrying high-dimensional information, could a simple death in the right manner grant him instant invincibility? Zhang Ge glanced at his laser rifle and asked his companions the name of the planet. Upon receiving the answer, "Vigilance," he exclaimed, "I've never had such a wonderful start."

However, when a casual touch of the laser rifle caused its machine spirit to tremble with joy, and when he seized the opportunity to poke his head out of the trench and kill a dozen heretics, and a shell slammed into the trench, sending shrapnel and shockwaves slicing through the entire platoon's position, killing thirty or forty allies besides Zhang Ge, but just avoiding him, he realized that things weren't as simple as they seemed.
