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

……

Player "Elena" has accepted your friend request.

Immediately afterwards, a private message popped up.

Elena: Mr. Lin, I can't believe it really is you!

[Elena: Mr. Lin, I just saw the announcement. You've reached the second level of the Earth's core?]

[Elena: What's the second floor like? Are the monsters strong? Are there many resources?]

Judging from the profile picture, Elena appears to be a young woman with blonde hair and blue eyes.

Lin You couldn't help but laugh out loud as she looked at the series of messages.

This Miss Elena was much more lively than he had imagined.

This is nothing like the "strategy author" on the forum who calmly analyzes the types of environments.

[Lin You: Don't get excited, speak slowly]

Elena: I'm so sorry, I got too excited.

[Elena: I absolutely love your guides! I've read each one several times!]

[Elena: Your post helped me a lot, it almost saved my life!]

Elena: So when I saw you added me as a friend, I was so happy I could die!

Lin You shook her head and typed a line of text.

[Lin You: I'll write a guide about the second level of the Earth's core tomorrow, then you'll know.]

[Elena: Really?! That's great!!!]

Elena: Mr. Lin, please be careful!

[Elena: If you need any materials, just let me know! I have plenty in stock!]

[Lin You: Thank you, I'll contact you if I need anything]

Elena: Yes! Mr. Lin, keep it up! I'll always support you!

Lin You closed the chat interface and leaned back in her seat.

"My little fangirl..."

He smiled and didn't think much of it.

There is still plenty of time; the minecart will take at least another twenty minutes to reach the second level of the Earth's core.

Instead of waiting idly, I might as well use this time to write something.

"The strategy guide for today hasn't been posted yet... perfect timing."

Lin You opened the thread section and created a new thread.

The title was quickly drafted:

Hidden Mechanics of the Undead Invasion! Another Path to the Second Nether!

In the main text, Lin You not only revealed the recipe and effects of the Spirit Summoning Lantern.

It also detailed the entire process of triggering the hidden mechanism today.

Repel 10 waves of undead invasions in succession at the same location.

The structure of the Earth's core will be destroyed, creating temporary passages leading to deeper depths.

The passage is open 24 hours a day and requires 100 units of fuel to pass through.

He also attached screenshots of the Earth's core tunnel and some information observed by the Eye of Insight.

"These are my findings for today, and I hope they will be helpful to everyone."

"If you want to trigger this mechanism proactively, you need to be fully prepared."

"The intensity of the 10 waves of undead invasion increases with each wave, and the last wave will have more than 20 undead appearing at the same time."

"It is recommended to use at least iron armor and weapons for the challenge, and to prepare sufficient supplies."

Good luck to everyone.

After writing the closing remarks, Lin You glanced at the time.

Day 6 of the survival game, just past midnight.

Click Publish.

As soon as the post was published, players who were following Lin You received a notification.

"Lin You, the master, has released a new strategy guide! Go check it out!"

"A hidden mechanism for the undead invasion? What is that?"

"Another path to the second level of the Earth's core? A way to get to the second level without finding the entrance?"

"Holy crap! Really?!"

Players flocked in, eager to see the post's contents.

Then, everyone fell silent.

After a brief silence, the comments section erupted in a chorus of groans.

"Clicking the same spot repels 10 waves of undead invasion?!"

"A final wave of more than 20 undead?!"

"Lin You, is this even a human being capable of completing this challenge?!"

"I can't even beat the first wave, and you expect me to fight ten?"

"Is this the difference between a pro player and an average player...?"

"I get it! Boss Lin You isn't human at all, he's a monster!"

"What kind of monster can fight off 10 waves of undead invasions in a row?!"

"I suspect that Boss Lin You is an army all by himself."

"No doubt about it, Boss Lin You's profession is definitely very powerful, maybe even a B-rank profession!"

"Even for a B-rank class, it would be difficult to solo 10 waves of undead invasions..."

"Master Lin You, please tell me, how did you do that?"

"Don't ask, it was just for fun."

The comments section was filled with a mix of lamentation and astonishment.

But regardless, all players reached a consensus—

Lin You's strength is far beyond their reach.

Lin You shrugged as she looked at the comments.

His original intention was to share a way to the second level of the Earth's core.

As for whether he can do it... that's not something he needs to worry about.

Lin You closed the forum and turned her attention back to the minecart.

The mine cart continued its journey in the darkness.

The rock walls on both sides of the passage began to change.

From rough rock, it gradually transformed into a mineral that shimmered with a faint fluorescence.

"We should be there soon."

Lin You sat up straight and gripped the bronze sword tightly.

Flame Spirit jumped up from his arms, its tail ablaze with flames.

At the end of the passage, a faint light appeared.

Lin You took a deep breath, her gaze resolute.

"The second level of the Earth's core... Here I come!"

You have arrived at your destination.

Current depth level: 2

Two lines of notification messages appeared before my eyes.

But what attracted Lin You's attention even more was the scene in front of the mine cart.

At the end of the passage lies a subterranean space.

Judging from the dilapidated wooden houses, abandoned farmland, and broken fences.

It appears that this place was once inhabited, but it has long been abandoned.

"It's a type of subterranean space I've never seen before."

"It seems... there's no danger?"

Just to be on the safe side, Lin You stopped the minecart and got off with Yan Ling to check.

As soon as he got close, his eyes heated up slightly, triggering additional information.

[Additional Information: You have discovered a subterranean site]

No monsters will appear in the underground ruins.

However, be wary of potential traps and defensive structures.

"So this kind of space is called the 'Earth's Core Ruins'..."

Lin Youmo silently noted down this information.

Since there are no monsters, it's relatively safe.

As for hidden traps and mechanisms... the Eye of Insight should remind me.

Filled with anticipation, Lin You began to explore this area.

But soon, he walked out of a wooden hut, disappointed.

"This place is so poor!"

There were no treasure chests in the house.

There wasn't even a single piece of intact wood.

Everywhere was covered in dust and moss, and there was a musty smell.

Most of the furniture was also rotten and would break at the slightest touch.

Fortunately, there are two wooden houses in the ruins.

The second cabin was not a complete loss.

As soon as Lin You opened the door, she saw a corpse leaning against the wall and was startled.

However, after waiting a few seconds, the corpse did not resurrect as a skeleton or zombie.

He breathed a sigh of relief and went forward to examine it carefully.

A discerning eye provides information in a timely manner.

[Additional Information: This is the remains of an adventurer, who was mauled by some kind of wild beast. Fortunately, his backpack is still intact.]

"Backpack!"

Lin You's eyes lit up. She first clasped her hands together to show respect for the remains, and then carefully picked up the dusty backpack.

You have obtained the "Adventurer's Backpack"
