21st Century Necromancer

In Chen Yu's Necromantic Space, the once-dormant foundry's production line for Undead Servants was reactivated, with the previously stored giant robots taken out once again. They were tirelessly working in a valley.

Within his Necromantic Space, besides building the castle where he and Jounouchi Hiromi lived and his own Mage Tower, Chen Yu had also constructed facilities such as a Soul Core Processing Factory, Mechanical Undead Foundry, Magic Greenhouse, Bone Dragon Summoning Circle, and a Blood Pool specifically for Jounouchi Hiromi.

These facilities were the foundation for a Necromancer to create their own Undead Legion and were also fundamental to a Necromancer's power and growth.

After constructing these facilities, Chen Yu had stopped developing his Necromantic Space and began to improve the environment within it instead.

After all, both he and Jounouchi Hiromi were still alive and preferred lush mountains and rivers and more beautiful natural scenery, rather than a true Necromantic Space filled with barren lands and skeletons and zombies crawling everywhere.

However, when Chen Yu originally constructed his Necromantic Space by severing a small piece from the Netherworld and projecting it down, this allowed his Necromantic Space to gain the Death Attribute, which made it more in tune with him. But it also affected the growth of living beings within the Space.

The plants in the Magic Greenhouse were relatively unaffected thanks to the adjustments from special Magic Arrays, but the turf and trees Chen Yu had initially brought in to greenify the area around the castle were clearly tainted by the necromantic aura and had started to mutate.

For Chen Yu, this situation wasn't too concerning. He simply controlled the mutations to an extent that they wouldn't affect the greenification nor cause any adverse effects on the Necromantic Space.

However, after Chen Yu became a Demigod and obtained a considerable amount of war booty from the United Kingdom, the once-silent construction in his Necromantic Space resumed.

Aside from the construction site in the valley, new factories had been built near the plains and river in front of the castle. At the river's estuary, a massive dock and berths were constructed. The Ghost Ships Chen Yu had brought back from the United Kingdom were now all docked not far away at sea. Inside the dockyard were several metallic wrecks, as though they had been submerged on the seafloor for many years, with numerous quadruped robots repairing these relics.

Chen Yu had intentionally sent these Ghost Ships to salvage the remains of famous battleships sunk during World War II. These relics, with their deep historical significance, were excellent materials for summoning Ghost Ships.

Previously, Chen Yu lacked the ability to utilize these materials, but now, as a Demigod of the Undead, he could fully revive these battleships.

Yet, Chen Yu didn't plan to simply use these materials to create Ghost Ships, which would be an underutilization and waste of such Legendary battleships.

More than that, Captain Kidd and his Island Fleet brought back from the United Kingdom certainly had Legendary-rank strength, but the Ghost Ships from the age of sail were a bit outdated. He planned to combine the two, trying to create something entirely new.

Speaking of which, Chen Yu used to be an admiral of the Ship-girls and had once called paper characters his wives. Now, it seemed he could...

Chen Yu hurriedly shook his head, dismissing the thought. His legitimate wife was now the Crimson Empress, who possessed the Legendary Dragon Bloodline, had broken through the Legendary-rank, achieved Life Level sublimation, and completed the inauguration ceremony. Even if the Ship-girls he summoned had Legendary combat power, they wouldn't stand a chance in a real fight.

So ship-girls are a possibility, but let's forget about any ideas that shouldn't exist.

Besides the battleships meant for summoning ship-girls, the engineering projects in the depression are also a focus of Chen Yu's attention.

What's being built here are also mechanical undead, only these are considerably taller than the four-legged robots used for construction, and their style is quite different.

The style of the four-legged robots is closer to steampunk, with their four delicate long legs that hold advantages in work and mobility, but they are utterly unskilled in combat.

In contrast, every inch of this massive mechanical undead is designed for war, with a more post-modern aesthetic.

This towering mechanical undead, like the four-legged robots, has four supporting legs, styled like those of a spider, but unlike the four-legged robots, these legs are extraordinarily thick, looking like four sturdy steel columns planted into the ground.

If the slender legs of the four-legged robots can be compared to the long legs of a white crane, then the supporting legs of the mechanical undead are akin to the sturdy legs of an elephant.

Atop these robust legs that could easily crush a tank are equally immense and burly torsos.

Chen Yu didn't construct this torso in a humanoid shape, as for super-large war machines, humanoid is the least useful design, with poor balance and difficulty fitting weapons, practical only for satisfying the unique tastes of giant robot enthusiasts.

The torso part of the mechanical undead currently under construction resembles a giant crab, with a back covered in thick, arc-shaped armor similar to a crab's shell, which is equipped with missile launch nests and anti-aircraft rockets. These are used not just for anti-aircraft purposes but also for missile barrages.

Naturally, the ammunition has been magically enhanced. The anti-aircraft rockets are replaced with barrages of Arcane Missiles, and if anyone tries to breach the airspace above this behemoth, they'll be taught a lesson by a barrage akin to that from a car-laden ambush.

As for the missiles meant to "cleanse the land," they are forbidden weapons meticulously concocted by Chen Yu. Each missile can trigger a necromantic catastrophe that includes, but is not limited to, plagues, curses, and desolation, truly a magical version of a nuclear bomb.

Below the arc-shaped armor are two turrets with quad-linked rotating cannons, their manufacturing technology pilfered by Chen Yu through the banshees from the naval gun technology of the United States military. With a caliber reaching 210 millimeters and barrels with a 50-caliber length processed using modern techniques and magic, the eight ominously dark muzzle slots stand as the most lethal weapons.

As for the cannonballs... Chen Yu didn't expend too much effort on these, only creating Dead Fire Shells and Cursed Cannonballs with burning effects, as well as powerful Fireburst Shells and Demon-Slaying Armor-Piercing Shells.

In addition to the main cannons, there are other weapons like defensive autocannons, close-protection machine guns, and rocket launch nests. The four-legged robots are now fitting this colossal entity with runic armor to enhance its defenses.

"The Undead Mech Sentinel is nearly complete, and the summoning of the ship-girls can start once those battleships are repaired. But the number of cannon fodder is still insufficient. Should I initiate that plan?" Chen Yu checked the progress of the projects, stroking his chin, pondering how he would respond if Izanami, as Yomotsu no Oni Kuni suggested, really broke through the barrier between life and death and emerged from the Land of the Dead.
