Chapter 624: Chapter 401: Upgrading the LV11 Lord’s Mansion!

    These resurrected corpses could only be salvaged for some top-quality materials or used as material for the Corpse Explosion Technique.

    As for wanting to use the Necromancer’s ultimate skill, “Rebirth,” to resurrect the corpses again, that was out of the question.

    The “Rebirth” skill required a wisp of residual soul and a relatively intact body, but these corpses, resurrected by some rule, lacked even a trace of a residual soul, having been completely expended.

    Moreover, once these resurrected bodies were killed again, they would not drop anything. Their only value lay in the mutated shells of the Epic Bosses they had become.

    Dragging them back for dissection and dismemberment could yield quite a bit of Epic-level material, which, for many life professionals, were undoubtedly first-rate materials.

    At least Number Two and the four sisters of the Fan Family would definitely want them, as Array Masters and Alchemists pursued top-tier materials far more than he, a Necromancer, did.

    After conducting several experiments and retrieving three Epic Boss corpses, Dilys returned.

    “Master, I patrolled within a 50,000-meter radius. Several times, I almost lost my sense of direction. This Eternal Night and Extreme Cold must have a disorienting effect.”

    “Have you discovered anything nearby?”

    This state of Eternal Night also concealed Spirit exploration and disoriented one’s sense of direction, especially when flying in the sky, making it exceedingly simple.

    “I discovered some resource points on the surface, all consisting of rare resources, and most of them are of superior quality or better.”

    “Did you find any bodies?”

    With the Underworld’s limitations on the surface, not having high-quality resource points would be unusual.

    However, extracting them wouldn’t be so easy.

    Just now, Zi Liyuan had summoned some Skeletons, and they turned into ice chunks the moment they appeared, shattering into pieces upon a single touch.

    Even summoned Skeletons that were of the ordinary monster template lord-level variety fell immediately.

    At the same time, Zi Liyuan realized that ordinary monster template creatures did not get resurrected after death on the surface world through mutation.

    Only the bodies of monsters with a Boss template would be revived and mutated, enhanced into higher Boss template monsters under the influence of some Rule Power.

    Of course, the Rule Power of the surface at most created Epic Bosses.

    “There were corpses discovered, but they were all frozen, and all were frozen bodies of Boss-type monsters, scattered rather sparsely.”

    Dilys’s words reminded Zi Liyuan of the experiment with summoning Skeletons he had just conducted.

    Ordinary monsters, once summoned, had their Life Force consumed instantly by the Eternal Night and Extreme Cold. In less than thirty seconds, the bodies shattered into ice fragments and merged with the permafrost.

    Only the bodies of Boss monsters remained frozen, without shattering and merging with the permafrost, even transforming and reviving when living creatures approached, then killing the living beings.

    A peculiar protective mechanism, so if one wanted to exploit surface resources, they needed to clean and retrieve all those frozen bodies.

    However, there was no rush for that. Although he severely lacked rare and superior-quality resources, he did not have enough manpower for development here.

    Ordinary monsters appearing on the surface were consumed and killed by the Eternal Night and Extreme Cold; only Bosses could be utilized. Yet most of the Undead Bosses Zi Liyuan controlled were high-level entities.

    As for the Bosses from the eight undead species within the Castle of the Undead, without any contracts, who knew if they would just run away when released.

    Expecting them to work hard was probably wishful thinking.

    After all, the intelligence of Bosses was comparable to that of normal humans and even surpassed that of humans.

    “Let’s go. We’ll leave this area for future development and explore the situation in the Underworld for now.”

    Zi Liyuan boarded Dilys with Old Iron and returned to the underground tunnels.

    As for investigating the insect nest’s whereabouts, it was temporarily abandoned.

    The other side’s escape was very resolute, obviously using the surface world as a passageway—and flying away. It was unrealistic to find any traces nearby.

    At this moment, the underground insect nest had been completely destroyed.

    The Spider Queen had absorbed all the energy from the mycelium, and those unhatched cocoons had all withered and died.

    After the mycelium had all its energy extracted, it gradually lost its activity, then dried into pieces of skin, cracking into countless fragments.

    Absorbing the energy and nutrients from the mycelium, the Spider Queen produced a large batch of grinding disc-sized spiders, which she released and used as scouts.

    The insect nest area occupied and transformed seven huge caves, but these were just the primary core areas, with an extensive range of territories surrounding these, which also fell within the insect race’s domain.

    The passageways in the Underworld were numerous; not counting those excavated by the insects themselves, the unique natural passageways of the Underworld had three connections to the insect race’s controlled territory.

    Essentially, each natural passageway, after a hundred miles or so, led to a vast cavern.

    These caverns sometimes contained resources or monster tribes, both strong and weak ones.

    The vast caverns near the insect nest area had already been completely ravaged by the insect race, stripped bare of any resources.

    This was truly a terrible situation.

    Indeed, where the insect race passed, nothing survived; not an empty reputation.

    Any substance with even the slightest energy, whether elemental or biological, was seized by these robber-like insects, turned into their fodder, and then used to spawn new insects.
