Skeleton's Enhancement

Here's the English translation of the provided Chinese text:

A new week, requesting collections, monthly passes, recommendation tickets, and all other forms of support!

After the Ghost Tree absorbed the two useful seeds, Gu Su wasted no more time. He turned and brought the various nourishing materials he had prepared, placing them methodically beneath the Ghost Tree.

The melted corpse oil was contained in an iron box, emitting a faint, fishy, and rotten odor.

The sludge transported from the cold storage was sticky and heavy, still carrying residual corruption energy.

Then there were the scattered remains of flesh and blood collected after killing the long-haired rats, though fragmented, they contained pure bloody essence.

Gu Su piled every material he could think of that could nourish the Ghost Tree at its roots.

As soon as the materials were arranged, the Ghost Tree's withered black branches stirred slightly. Countless fine root hairs quietly emerged from the soil, like greedy tentacles, slowly coiling around the iron box of corpse oil, the sludge, and the remains, drawing out their energy bit by bit.

As the energy was absorbed, the Ghost Tree's repair progress panel flickered, finally settling at 34%. The previously slightly shriveled branches became firmer and more lustrous.

At the same time, a subtle vibration came from the ground beneath Gu Su's feet.

Gu Su bent down, touching the ground with his fingertips. He could clearly feel that the soil in the graveyard had become much firmer, no longer soft and easily sunken as before.

Clearly, after absorbing the corrupting energy from the sludge, the Ghost Tree had converted the excess impurities into material to fill the soil.

It had completed its self-repair and optimized the graveyard's terrain – killing two birds with one stone.

Sensing this change, Gu Su understood that the Ghost Tree's functions had partially recovered.

Nourishing the Ghost Tree was complete. The remaining task was the disposal of the monster corpses.

For the two Harpy corpses, Gu Su didn't hesitate. He waved his hand, signaling two skeletons to step forward and drag the bodies to the side of the Level 1 Empty Grave, throwing them in directly.

Although Harpies were strange creatures, their corpses were fresh and their energy ordinary, perfectly meeting the conversion requirements for a Level 1 Empty Grave.

As soon as the corpses landed in the empty grave, a faint gray spectral energy rose from the mound, enveloping the bodies and rapidly dissolving them into the grave.

[Empty Grave automatically uses your Necromancy (Level 1), gains Skeleton (Level 0) * 2, Necromancy proficiency +2 points.]

The moment the system prompt sounded, two brand-new skeletons slowly crawled out of the empty grave. Though their forms were slightly slender, they already possessed basic combat capabilities.

Including the six skeletons summoned using Necromancy after killing the long-haired rats, plus the two skeletons already in the Level 1 Empty Grave.

At this moment, the Level 1 Empty Grave had reached its full capacity. A total of ten skeletons stood neatly beside the grave mound, awaiting Gu Su's command.

Looking at the situation, Gu Su did not hesitate. He immediately chose to strengthen the Level 1 Empty Grave towards the grave head.

This was the optimal strengthening path for a Level 1 Empty Grave and a step he had long planned.

[Grave Head (Level 1): Resident undead type and quantity remain unchanged. Resident undead upgrade from Normal to Elite (Skeleton Attack +1, Defense +1, Health +3).]

The moment the system prompt fell, faint gray spectral energy surged into the Level 1 Empty Grave like a tide.

It then transferred to the ten skeletons outside the grave.

Their bodies began to undergo noticeable changes. Their forms subtly grew by about a third, and their originally slender bones became thick and solid, emitting a faint grayish-white luster.

Even more surprisingly, a layer of worn but tough bandages automatically wrapped around the joints of their limbs and torso, securely fixing the bones.

This was clearly to further enhance their defensive capabilities, preventing them from being easily shattered during combat.

After the strengthening, the aura surrounding these ten Elite Skeletons was completely different.

Compared to the slender, ordinary skeletons responsible for labor on the other side of the grave mound, their presence was more powerful, and their stances were upright and orderly. It was clear at a glance that their paths were different.

The skeletons by the grave mound focused on quantity and labor efficiency, while these Elite Skeletons were considered combat units.

But Gu Su did not stop strengthening them there.

His gaze swept over the piled materials nearby, landing on the items reserved for separate processing.

Rusted shelf angle iron, sharp ceiling fan blades, and dismantled car parts – these were all top-quality materials for crafting basic weapons.

The combat power of undead creatures, besides their own level and attributes, was also crucial with the enhancement of weapons. Gu Su intended to equip these skeletons with all-metal weapons.

"Come here, take these things and see how you can make weapons more conveniently."

Gu Su gave the command to the ten Elite Skeletons, letting them choose their own weapons.

He then turned to the other four sturdy skeletons. "You four, carry this Lion King corpse to the Level 2 Empty Grave over there."

That Level 2 Empty Grave was vastly different from the Level 1. It wasn't an empty pit but a broken coffin with its lid pried open.

The surface of the coffin was carved with blurred undead patterns, emitting a dense Yin energy, specifically used for converting zombies, ghouls, and similar undead.

The four sturdy skeletons immediately bowed in acknowledgment. They jointly gripped the enormous body of the Corrupted Jungle Lion King and steadily lifted it, walking step by step towards the coffin of the Level 2 Empty Grave.

Just as they were about to place the Lion King's corpse into the coffin, a crisp "ding" suddenly sounded in Gu Su's mind.

[Core creature corpse (Level 2) discovered. This item is necessary for upgrading the Graveyard Demon. Do you wish to place it in the Empty Grave for conversion?]

"Core creature corpse?" Gu Su clearly froze, his eyes full of confusion.

Although he was only a necromancer with basic abilities, and his studies were limited to introductory necromancy knowledge, he did understand the classification and utilization of corpses.

The main forces of undead troops had increasingly stringent requirements for corpses as the level of the Empty Grave increased, a fact known to every necromancer.

A Level 1 Empty Grave could convert skeletons with just fresh corpses, while a Level 2 Empty Grave required strong corpses to transform into zombies or ghouls.

A Level 3 Empty Grave required corpses with sentience to be converted into ghosts.

Level 4 Empty Graves require high-constitution corpses plus blood to transform into vampires.

Level 5 Empty Graves require corpses with magical talent plus materials like magic staffs and spellbooks to transform into ghouls or liches.

Level 6 Empty Graves, in addition to a corpse, require a longsword, a full set of armor, and the corpse of a mount to transform into death knights.

Level 7 Empty Graves are directly called Dragon Tombs, and only dragons, even velociraptors, can be buried within.

However, this term "core creature corpse" was something Gu Su had never heard of before.

How could this thing be related to the upgrade of the Graveyard Demon?

Gu Su looked puzzled, but after thinking for a moment, he finally had the skeleton place the corpse of the Shadowed Jungle Lion King down.

He returned to his tent to check the relevant information.

Since he had obtained the core creature's corpse, the upgrade requirements for the Graveyard Demon could now be viewed.

Seeing the standards and requirements for the Graveyard Demon's upgrade, Gu Su couldn't help but frown.
