From above, one could see William, Serena, John, and Mylon charging into the palace of the Ring of Nul at the forefront, leading the Astartes in an uneven battle against the high-ranking demons and demon guards stationed inside.
Serena removed the hilt hanging on the right side of her Emperor Belt and inserted the chip into it, transforming it into the Sword of Hades.
Then, before the eyes of the Astartes, Serena displayed the swordsmanship possessed by an Artificial Intelligence.
Even when Serena advanced too far and found herself surrounded, she could still maneuver among the demons with ease, working with the Astartes to cut down the demons surrounding her.
As William's secretary and wife, Serena almost never fought personally, but that did not mean her combat ability was weak.
Intelligent AIs could download every existing sword technique, saber technique, and various fighting skills in the world, then master them in an extremely short time.
Combined with an Anthropomorphic Prosthetic Body or a T-X skeleton, Intelligent AIs were even more like Terminators than the Terminators themselves, possessing both agility and strength.
With the support of the Emperor Belt, Serena's combat power had risen by several levels.
William, who had been following right behind Serena the entire time, seemed somewhat lazy by comparison.
He merely removed Upsilong's phone, flipped it open, and transformed it into a pistol, using energy rounds created from Photon Blood to deal with those demons who never learned their lesson from a distance.
John and Mylon?
One wielded Thor's Hammer and fought like an unstoppable warrior, while the other operated a 1.25-caliber Ultra-Heavy Bolter, seemingly eager to demolish the entire palace.
The bodyguards and Imperial Guard Terminators slaughtered the demons with the assistance of their auxiliary systems, as if they were playing a video game.
"Pfft! Pfft!"
