Survival in the Core: I'm writing a guide for the entire server.

On the minimap, countless red dots began to appear.

One, two, three...

In less than ten seconds, the number of red dots exceeded ten.

boom!

The ground cracked open, and a white, bony claw emerged from the fissure.

Then came the second, the third, the fourth...

Skeleton soldiers crawled out of the ground, their eerie blue flames flickering in the darkness.

But this time, in addition to the skeleton soldiers, there is another kind of undead.

They emerge from the ground more slowly and their bodies are more bloated.

The rotting skin was covered with mold and pustules, emitting a nauseating stench.

……

[Zombie]

[Level: 2]

【Life: 60/60】

[Defense: 10]

[Skill: Corpse Poison Spray]

[Weaknesses: Vulnerable to fire and holy damage, slow movement speed]

[Note: Ordinary undead, with higher defense than skeleton soldiers, but slower speed, best dealt with using ranged or fire attacks]

……

"A mixed formation of skeleton soldiers and zombies."

Lin You quickly assessed the enemy situation and summoned a group of kobold miners from the Magic Card Encyclopedia.

More than a dozen summoned creatures lined up in front of him, forming a defensive line.

"Flame Spirits are effective against fire damage, but they will return to rest when their magic is depleted."

"Meow!"

Flame Spirit moved like lightning, rushing towards the nearest zombie.

Meanwhile, the kobold summons also clashed with the skeleton soldiers.

Ten kobold miners surrounded five skeleton soldiers.

The inferior stone pickaxe clashed against the bone, making a cracking sound.

The battle has officially begun.

Lin You was not idle either.

He gripped his bronze sword tightly and slashed into the battlefield from the side.

They specifically target skeleton soldiers who are entangled by kobolds.

Although the slash damage is halved, with the kobolds keeping him occupied, he can slowly whittle down the enemy's health.

One, two, three...

The skeleton soldiers fell one after another.

Some triggered "return to death," where the broken bones were pieced back together.

But before it could attack, it was lashed out again by the Flame Spirit's tail.

The battle lasted less than five minutes.

The last zombie fell, and the battlefield returned to calm.

[Battle over! You have repelled the invasion of the "Undead Scourge"!]

You have killed 6 "Skeleton Soldiers" and 4 "Zombies"!

[Experience points +220! Current stats: 685/500]

[Level Up! Current Level: 6 (185/600)]

Based on the attribute growth of "Card Master", you have gained 10 free attribute points!

A dark golden light burst forth from Lin You's body, and an upgraded, refreshing sensation spread throughout his entire being.

"I've reached level six."

Lin You took a deep breath and felt the power within her body increase again.

He crouched down and turned all the undead corpses on the battlefield into magic cards.

[Card crafting successful! You have obtained "Magic Card: Skeleton Soldier" x6!]

[Card crafting successful! You have obtained "Magic Card: Zombie" x4!]

[Consumes 200 mana points, current mana: 320/580]

Lin You has already collected the Skeleton Soldier Magic Cards.

The effects of the zombie's magic card are similar.

After absorption, it can increase the constitution attribute by 1 point.

The maximum upgrade is 30 points to Level E.

This is good news for Lin You.

Unlike the "Willpower" attribute boosted by skeleton soldiers.

The importance of the "Constitution" attribute is beyond doubt.

It affects the upper limit of life and physical strength, and is crucial to survival ability.

"Let's do it again."

Lin You casually added the 10 free attribute points from the upgrade to "Spirit" and began cleaning up the battlefield.

Scattered across the chaotic battlefield were many materials.

Skeleton soldiers dropped "Undead Bones" x6

The zombie dropped 3 "corpse oil" and 4 "rotten flesh".

"The materials are back."

Lin You nodded in satisfaction and put the materials into her backpack.

The cost of making a Spirit Lantern is 5 copper ingots, 5 undead bones, and 1 portion of corpse oil.

After this wave of activity, he not only recouped his costs but also made a profit.

Not to mention the gains from experience points and magic cards.

"continue."

Lin You returned to the minecart and took out the second Spirit Summoning Lantern from the treasure chest.

He walked to an open space and smashed it again.

The eerie green flames burrowed into the ground, and red dots appeared on the minimap.

This time, there are more undead than last time.

Skeleton soldiers x6, zombies x6.

A total of 12.

However, Lin You's card collection currently contains more than ten Kobold Miner cards.

There are 6 skeleton soldiers and 4 zombies.

The firepower is much stronger than in the first wave.

"call!"

With a thought, Lin You summoned the newly created Necromancer Card from the encyclopedia.

The skeleton soldiers and zombies who were just fighting him suddenly appeared out of nowhere.

Standing next to the wounded dog-headed people, it looked somewhat eerie.

"Go! Defeat them quickly!"

The summoned creatures swarmed forward, engaging the undead in a chaotic battle.

The Flame Spirit traversed the battlefield, its magic still abundant, each swipe of its fiery tail taking away a dead soul.

Lin You stood in the back row, holding a bronze sword, ready to provide support at any time.

In less than three minutes, all 14 undead fell.

[Battle over! You have repelled the invasion of the "Undead Scourge"!]

You have killed 8 "Skeleton Soldiers" and 6 "Zombies"!

[Experience points +350! Current stats: 535/600]

[Card crafting successful! You have obtained 8 "Magic Card: Skeleton Soldier" and 6 "Magic Card: Zombie"!]

You have obtained "Undead Bone" x8, "Corpse Oil" x6, and "Rotten Flesh" x8.

As Lin You watched the experience bar rise rapidly, the corners of her mouth curved into a wider smile.

This isn't grinding monsters, it's clearly farming money!

The third wave, the fourth wave, the fifth wave...

Wave after wave of undead calamities were triggered, only to be crushed by Lin You and his summoned creatures.

With each battle, his experience points skyrocketed.

With each battle, his collection of magic cards grows.

He gains a lot of materials from each battle.

The level increases from level 6 to level 7, and from level 7 to level 8.

All attribute points were added to Spirit, and the maximum magic power exceeded 700.

The number of skeleton soldiers and zombies in the Magic Card Encyclopedia has surpassed that of the Kobold Miner.

They became his most numerous summoned creatures.

The tenth wave.

Lin You made the last spirit-summoning lantern at the workbench.

"After this round, I'll have used up my daily quota."

Lin You took a deep breath and smashed the lantern.

The eerie green flames burrowed into the ground.

But this time, the number of red dots appearing on the minimap far exceeds any previous wave.

Skeleton soldiers x15, zombies x10.

A total of 25!

"A big one is coming!"

However, Lin You remained completely calm.

Because the undead army in front of him was not inferior in number at all!

Yanling was also eager to try, but he pulled her into his arms.

"Your magic is almost used up, so just stay put in the back."

"Meow~"

Upon hearing this, Yanling felt a little regretful, but she still obediently nestled in Lin You's arms.

"kill!"

At Lin You's command, the summoned army and the undead began their final battle.

The underground space, which was originally occupied by earthworms, was instantly filled with eerie sounds of the undead clashing.

The battle lasted for nearly ten minutes.

The last skeleton soldier fell, and the battlefield returned to calm.

[Battle over! You have repelled the invasion of the "Undead Scourge"!]

You have killed 15 "Skeleton Soldiers" and 10 "Zombies"!

[Experience points +625! Current stats: 890/1000]

[Level Up! Current Level: 9 (890/1000)]

That's right, after frantically grinding monsters, Lin You's level has reached level 9!

Although the experience gained in the last wave didn't allow him to level up.

But it's only 110 experience points away from level 10.

"call……"

Lin You breathed a sigh of relief and glanced at her attribute panel.

……

[Player: Lin You]

【Occupation: Card Master (S-rank)】

[Level: 9]

Experience points: 890/1000

【Life: 200/200】

[Magic Power: 340/920]

[Stamina: 80/200]

【property:】

Strength: 20/100 (E-rank)

[Constitution: 20/100 (Grade E)]

[Spirit: 92/100 (E-rank)]

[Willpower: 12/100 (Rank E)]

[Luck: 10/100 (E-grade)]

……

His mental attributes are about to reach the E-level limit.

The total amount of magic power is about to break through four figures!

Compared to other players, his growth rate was terrifying.

But this is not enough.

He needs greater strength to survive longer in the inner world.

"Let's clean up the battlefield."

Lin You squatted down and turned all the undead corpses on the battlefield into magic cards.

Because there were too many corpses that could be made into magic cards, he took a break to recover his magic power.

[Card crafting successful! You have obtained 15 "Magic Card: Skeleton Soldier" and 10 "Magic Card: Zombie"!]

He opened the Magic Card Encyclopedia and took stock of his forces.

Kobold Miners: 8 in total, most of which were lost in the initial waves of undead invasions.

Skeleton Soldiers: 40, the most numerous Magic Card, because they have the "Return by Death" skill and suffer almost no losses.

Zombies: 25 in total. Due to their thick skin and tough flesh, they are very suitable for use as meat shields.

"It's almost equivalent to a small legion."

Lin You nodded in satisfaction, took out 10 Skeleton Soldiers and 10 Zombie Demon Cards from the encyclopedia, and absorbed them on the spot.

[Absorption complete! Your Constitution and Willpower attributes have increased to E-rank by 30 points!]

Lin You closed his eyes, feeling the immense power within his body.

The spoils from this haul were quite plentiful.

Bones of the Dead: More than 60 pieces.

Corpse oil: more than 40 portions.

Rotten flesh: more than 50 pieces.

These materials are enough for him to make dozens more spirit lanterns.

"I've used up my credit limit for today, I'll try again tomorrow."

Lin You stretched, feeling sore all over.

Ten waves of undead invasions followed, although summoned creatures fought most of the time.

However, as the manipulator, he also suffered considerable mental strain.

Just as he was about to return to the mine cart to rest.

Suddenly, a loud and eerie noise came from behind!

It was like an earthquake; even the ground began to shake!

"What...what happened?!"

Even Yanling was startled awake, staring wide-eyed as she climbed onto Lin You's shoulder.

Together with their owner, they looked in surprise in the direction from which the sound came—

Suddenly, a deep pit appeared in the ground, which had been riddled with holes by the undead emerging from the earth.

As Lin You gazed at the dark pit, lines of information appeared before her eyes.

[You clicked in the same location and repelled 10 waves of undead invasion, triggering a hidden mechanism!]

The current structure of the Earth's core has been destroyed, creating a passage to a deeper inner world!
