2 Xp farm or a Dungeon

The Xp farm was perfect for getting large amounts of XP. While he had a lot of XP, he didn't think it would be enough, and the XP bottles were kept for emergencies.

He went to the "Undead Dungeon" where all the undead were in-game Phantoms, Zombies, Skeletons and their variants like Husk, Strays, Wither Skeletons to special mobs mutant zombies, skeleton dragons, ghosts, mummies, specters, etc.

The Xp farm was different from the traditional Xp farm and was made similarly to a dungeon from fantasy stories; it also was a good way to train.

Ook, the "Undead Vanquisher" set from inventory. It was nothing much, only an iron sword that had effects that would give extra damage to undead, and combined with his [Ethereal Strike] skill, it would be deadly, but since this skill consumed Xp, he will only resort to it when the situation is dire.

[Equipment - Iron Sword

Enchantments - Smite II, Sharpness IV, Unbreaking III, Fire Aspect II, Looting III]

He also took Healing Potion 'grenades' to deal with the more problematic undead.

(I know Smite and Sharpness are incompatible but this does not follow normal Minecraft mechanism)

As he was about to venture, he received another notification.

[Ding! Zombie Vanquisher.

-Slay 100 Zombies in a day.

-Rewards- Random Rare Holy Magic, 2X Experience Points]

Seeing this Ender was more than delighted.

He entered the first floor of the dungeon where only zombies were there.

The Zombies looked a mix of Resident Evil game and Minecraft zombies, Ender felt disgusted by their appearance and couldn't wait to slay them so that he could stop torturing his eyes.

The Zombies were in small groups of 2-3 and didn't notice Ender; he carefully approached a zombie and attacked the zombie with precision, severing his head as the rest of its body burned to ashes in a few seconds; Ender looked at this scene in amazement.

"It is way easier than expected," he thought. "With this, I can complete the quest in hours." And he rushed towards the zombies, careful enough not to get hurt.

And it was a slaughter; in less than half an hour, Ender completed the quest without even breaking a sweat.

[Congratulations on completing the quest.

-Holy Magic Rare Card, 2X Experience Points effect received.

[Zombie Killer - Does 5% extra damage to all zombies.

[New Quest - Ribcage Shattered

-Slay 100 Skeletons in a day.

-Rewards- Random Rare Dark Magic, 50 Skeleton Skulls]

Seeing the strings of notifications, Ender confirmed one thing: the Quest System worked on his thoughts and actions, which was good; he didn't want to end with the Slaver system after all, and there were not even penalties for failing the Quest, which was another good thing.

Ender took a shield out of inventory. Unlike traditional shields that were mixed with wood and iron, this was made from Vibranium, which was a famous metal from the Marvel Universe, and it was possible due to the various mods, and Ender included Marvel and various other fiction too.

[Equipment - Vibranium Shield

Enchantments- Thorns III, Unbreaking III, Loyalty, Protection V.

Special Ability- Absorbs Kinetic Energy and releases it on the user's command.

Can generate a forcefield in any direction using stored kinetic energy.]

(It doesn't consume Xp since it works on science.)

As for why he didn't have a vibranium suit it is not that he didn't have it, but because he had kept it somewhere else, and getting it from there would be problematic, with his strength.

He entered the second floor and the skeletons were roaming but when they spotted him their hollow eyes gained a malevolent shine, their rattling becoming restless as they attacked him with arrows, the arrows were moving slowly from Ender's perspective, easily dodging he jumped between them, slashing through their bones easily.

[Congratulations on completing the quest.

-Necromancy Rare Card, 50 Skeleton Skulls.

-Due to excellent performance you have received a new title - [Bone Breaker]]

[Bone Breaker -

-Bone Shatter Chance: Increases the chance of critical hits that shatter bones, leading to additional damage and disabling enemies by breaking their limbs.

-Enables you to sense weak points of someone's skeleton.

-Deals extra damage to armored enemies.]

After dealing with further floors he reached the 9th floor till now he faced no challenge and it was mostly easy, he expects more from the Boss on the 10th floor hoping it would provide some challenge.

Ender ascended to the 9th floor, his footsteps echoing on the cold stone steps. The air grew heavier, tinged with the scent of decay. He entered a dimly lit hall where skeletal warriors and decaying zombies roamed side by side, an eerie sight as hollow-eyed skeletons clinked and zombies dragged their rotting feet across the stone floor.

The Skeletal Warrior and Armored Zombieare two distinct and formidable types of undead mobs in the dungeon:

Skeletal Warrior

- Description: The Skeletal Warrior is a skeletal soldier reanimated through dark magic. Unlike ordinary skeletons, it's highly trained in combat and moves with precision, as if retaining echoes of its former life's skills.

Abilities:

- Bone Shard Volley: When threatened from a distance, Skeletal Warriors can hurl sharpened bone fragments as projectiles, dealing moderate ranged damage.

- Deadly Precision: They have higher accuracy and can perform critical strikes that ignore a percentage of armor.

- Bone Resilience: Due to the residual enchantments on their bones, they take reduced damage from slashing and piercing attacks, making them tougher to kill than regular skeletons.

Armored Zombie

-Description: The Armored Zombie is a heavily decayed corpse encased in ancient, enchanted armor. Though slow-moving, its added protection makes it a dangerous foe to unprepared adventurers.

- Abilities:

- Undead Endurance: Armored Zombies have high health and natural resistance to slashing and piercing weapons. They can absorb significant damage, making them difficult to defeat in prolonged combat.

- Poison: They passively release a poisonous gas that can kill a normal human.

These two undead enemies make a dangerous combination on the battlefield. The Skeletal Warriors provide strategic attacks and accuracy, while the Armored Zombies act as durable tanks, absorbing blows and forcing opponents to fight in close range where their decay aura can weaken their enemies.

As he approached, a system prompt appeared before him:

[Quest: Defeat the Undead Legion]

Objective: Eliminate 100 skeletal warriors and 100 zombies

Bonus Objective: Defeat all enemies within 30 minutes

Reward: 100 Gold Ingots, High Potion, Rare Necromancy Spellbook and Rare Holy Spellbook.]

Ender accepted the challenge without hesitation.

The undead immediately noticed him. The skeletons drew back their bows, launching volleys of arrows, while the zombies lumbered forward, groaning and swiping with decaying hands.

With a swift leap, Ender dodged the first barrage of arrows, using his power to strike back at skeletal enemies with increased force. Each swing of his sword shattered bones and cleaved through zombies with ease. Arrows that came too close were deflected by his Vibranium Shield, which absorbed the kinetic energy and built up a charge.

Using the shield's special ability, he released the stored energy, sending out a concussive blast that threw a cluster of zombies backward. Their bodies collided with the skeletons behind them, shattering some on impact and weakening others.

Ender took advantage of the chaos, slashing through enemies with precision. He managed to dodge every blow, dancing between his foes with fluid, calculated movements. Each time he struck a zombie, the Bone Breaker title activated, increasing his critical damage against these undead enemies.

As he fought, the timer ticked down, but Ender pushed on, determined to meet the bonus objectives. Just as the final skeleton fell, he had only a few seconds left.

[Quest Complete!]

[Bonus Objectives Achieved!]

Rewards:

- 100 Gold Ingots

- Enhanced Healing Potion

- Rare Dark Spell Card and Holy Magic Spell Card

- Bonus Item: Holy Blade of Vanquishing

- Bonus Title: Undead Slayer]

[Title: Undead Slayer]

Description: The Undead Slayer title is awarded to a warrior who has devoted themselves to the eradication of all undead. Bearing this title marks the individual as a sworn enemy of dark forces, with both strength and resilience against creatures of death and decay.

- Effects:

- Slayer's Edge: Deals an additional 25% damage to undead foes, whether they're skeletons, zombies, wraiths, or other dark entities.

- Undying Will: Grants 15% resistance to necrotic damage and dark magic, reducing the effectiveness of curses and life-drain attacks used by the undead.

- Aura of Courage: Inspires allies within a 20-foot radius, making them resistant to fear effects commonly employed by undead creatures.

[Item: Holy Blade of Vanquishing]

- Description: The Holy Blade of Vanquishing is a radiant sword blessed by divine powers specifically to combat undead foes. Its edge glows with a faint golden aura, growing brighter in the presence of dark creatures. It is believed to be forged from a rare celestial metal that holds a sacred enchantment, making it particularly deadly against creatures from beyond the grave.

Material: Adamantine

Enchantments: Unbreaking V, Sharpness X, Slash V, Smite X, Loyalty.]

- Special Abilities -

- Radiant Cleave: Each strike against an undead enemy unleashes a burst of holy energy, dealing additional radiant damage and stunning them briefly.

- Consecrate Ground: When the sword is plunged into the ground, it creates a temporary 15-foot radius area of holy energy that weakens undead creatures, reducing their speed and damage output by 20% for 30 seconds. Can be used once every 5 minutes.

- Light of Purity: The sword's blade emits a gentle light that disrupts illusions and reveals invisible or hidden undead within a 30-foot radius.

- Divine Retribution(Bonus Effect): If the wielder falls in battle while holding this blade, a burst of radiant energy is unleashed, dealing damage to all undead within a 50-meter radius.]

(Due to being made from Adamantine it consumes 50% less Xp when using special abilities.)

With his new loot and skills, Ender looked up at the staircase leading to the next floor. The rewards were helpful, but he knew greater challenges lay ahead he took the sword replacing it with the previous iron sword whose blade was chipped after the slaughter done by him.

He could feel the holy aura emitted by it, just by holding it, he felt 'hope' and strength.

Since he knew what lay ahead of the Boss mob he decided to draw the cards.

He had two rare holy and two necromancy magic cards he didn't know what to think about them both were opposite of each other.

He was also curious about it since his world didn't have any such things.

He used the cards and information about them appeared in his mind.

[Holy Light: Creates a radiant beam of holy magic that strikes multiple targets, dealing moderate holy damage and temporarily blinding the target. If the target is undead or a dark creature, the damage is doubled, and the blindness lasts longer.]

[Blessing of Fortitude: Bestows a temporary shield of light on the caster or an ally, reducing incoming damage by 30% and providing immunity to debuff effects for 30 seconds. Doesn't work on those stronger than caster.]

[Dark Mist: Summons a cloud of dark mist that spreads in a radius, causing enemies within it to suffer from slowness, nausea, and a mild poison effect.

Allies are unaffected.]

[Spectral Servant: Summons a ghostly servant to assist the caster by attacking enemies and other things. The servant is intangible and can pass through solid materials, making it useful for bypassing barriers or creating distractions.

The more you summon them the more Xp/mana it consumes.

The Spector's strength can't be stronger than D-:level (peak human) strength.]

"These are pretty useful spells," Ender says impressed he now didn't have much reservation in using Xp for special abilities or spells considering his Xp level was in the thousands he thought there may be a limit to levels but he did not have encountered till now except Xp level increasing has become difficult needing more Xp but it was not a problem since he didn't need to 'level up' to strengthen himself.

The Xp was his magic capacity and if his theory was correct then he had no limit to his magic capacity he would be able to cast any spell as long he had enough Xp-levels.

He estimates with his magic capacity alone he is in the "High" level where weaker demi-gods are placed.

Ender entered the tenth floor, where the first boss of the Undead Dungeon was, its overall power level being B- (city-level) the floor was like a separate dimension, it was a fog-shrouded realm, a twisted graveyard suspended between life and death. The ground is like a cracked bone and the air hums with necromantic energy.

The dark clouds occasionally cackle with green lightning he would have difficulty seeing anything if not for his eyes which were actually the effect of his in-game avatar's skin.

It was a discovery that left him in both joy and regret, if he would have known that he would transmigrate inside the game after dying for the first time and would get the abilities of the avatar's skin then he would have taken skin of some super hack character like Goku, Hulk, Rimuru, etc. But what can he do still something is better than nothing.
