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

Lin You handed over the medicine, which Qi Chuan took and tilted his head back to gulp down.

[Small healing potion has taken effect, Health +50]

Qi Chuan leaned against the rock, panting heavily, and it took him a while to recover.

His wound stopped bleeding, and his pale face regained some color.

"Boss, what brings you here all of a sudden?"

"I used a teleportation item, or you approved the application yourself."

Lin You glanced at the undead still gnawing on corpses deep in the mine tunnel.

"You go back to the minecart first, I'll take care of those enemies."

Qi Chuan nodded, struggled to his feet, and returned to the mine cart parked not far away.

His mine cart consisted of only one carriage, with several dents on the sheet metal, indicating that it had been through many battles.

The enhanced undead invasion, although it involved significantly more enemies, was still child's play for Lin You.

Before long, his collection of cards had been expanded to include dozens of low-level undead cards.

"Tell me what happened."

After getting into Qi Chuan's carriage, Lin You casually asked.

"I was overjoyed when I discovered this underground river while digging here today."

As he spoke, Qi Chuan excitedly licked the corner of his mouth.

He accidentally aggravated his wound and started grimacing again.

Lin You understood his feelings quite well; the underground river meant an inexhaustible source of water.

In the inner world, clean water is a valuable commodity, and Qi Chuan can make a lot of money thanks to this river.

"Go on."

"I had just walked to the riverbank and hadn't even started drawing water when someone dug a hole through the rock wall next to me."

"Those three bastards attacked me without saying a word after they saw me."

"I didn't bring any weapons. How could I possibly fight them all by myself? I ran around the minecart several times, chasing them all the way to the end of the riverbank..."

Qi Chuan's voice trembled slightly as he spoke.

"Boss, if you hadn't come, I would be dead here today."

Lin You narrowed her eyes. The three people were clearly not from Qichuan; it was just a chance encounter.

"By the way, boss."

Seeing Lin You deep in thought, Qi Chuan suddenly spoke.

"I have a video here, do you want to see it? I started recording it after the attack."

"I originally planned to upload this to the forum before I died, so I could at least die knowing why, but I didn't expect... hehe, I didn't die."

"Oh? Let me see."

Lin You raised an eyebrow, quite surprised, thinking to himself that this kid was indeed clever.

After receiving the video from Qi Chuan through her friend list, Lin You finally learned what had happened before his arrival and couldn't help but frown.

"These guys are the 'newcomers' after the merging of the newbie zones."

"But this group of people are too ruthless. It must be because that's the atmosphere in the newbie zone they were in before."

"Hmm... this incident should serve as a wake-up call."

Lin You saved the video, then glanced at the remaining time; there were still about 30 minutes left.

The Friend Teleport Card allows him to instantly teleport to his friend's side, but he cannot stay there indefinitely.

He can only stay for a maximum of one hour, during which time he can return to the previous location at any time.

If you do not return by the time the timer expires, you will be forcibly teleported back.

"Take care of yourself, I'm leaving."

"Hey, wait a minute, boss!"

Seeing Lin You about to leave, Qi Chuan endured the pain and stood up.

"I don't have much to repay you with, but there's a river here. Would you like to take some water back with you? I have some empty bottles here."

"...Alright."

Lin You thought about it and did not refuse.

Anyway, he's pretty free now, so he'll just browse forums when he gets back.

The two walked to the riverbank, and Lin You casually glanced at the flowing underground river before suddenly letting out a soft exclamation.

"Is there...something in this river?"

[Additional Information: Several piranhas inhabit this underground river. They will attack any creature that approaches the water's surface; attempting to draw water from it will result in them attacking you.]

……

Piranhas

[Level: 3]

【Life: 20/20】

[Skills: None]

[Weakness: Slows down after leaving the water, and takes 50% more damage from electric shock]

……

"It's a good thing you didn't fetch water earlier."

Lin You smiled and shook her head.

"There are piranhas in this river."

"If those three people didn't have bad intentions, you should thank them."

"what?"

Qi Chuan stared wide-eyed at the flowing water in disbelief.

"I knew this underground space couldn't be safe; it's underwater!"

"Boss, what should we do next?"

"No problem."

Lin You shrugged.

"Watch me."

He raised his right hand, and white arcs of electricity danced between his fingers, crackling with the sound of electricity.

—Lightning Bolt!

A bolt of silvery-white lightning shot out from his palm.

It accurately hit the nearest shadow beneath the water's surface.

The electric current exploded, splashing water everywhere.

A palm-sized, silvery-black fish floated to the surface, belly up.

Its whole body was convulsing, and its gills were still twitching slightly.

Piranhas only have 20 health points, so using lightning arrows to deal with them is like using a cannon to kill a mosquito.

But for Lin You, as long as it works, that's enough.

The remaining five piranhas, like an enraged pack of wolves, charged wildly toward the riverbank.

They leaped out of the water, opened their mouths full of sharp teeth, and lunged straight at Lin You's face!

Lin You neither dodged nor evaded, and shot out bolts of lightning in succession.

Crack!

Only one piranha rushed towards him.

Just then, a fiery red shadow pounced and knocked the last piranha away.

Upon closer inspection, it turned out that it was Flame Spirit who had killed the last enemy.

He was carrying the dead piranha in his mouth when he came over to Lin You to claim credit.

"Well done, this fish is yours."

Lin You patted Yan Ling's little head and glanced at the battle prompts.

You have killed 6 piranhas.

[Experience Points +6 (Accumulated experience during advancement quests)]

You have obtained 6 pieces of "Piranha Meat".

You have obtained 2 "Claw Hooks"

Lin You retrieved the spoils from the ground and examined them carefully.

Piranha meat: A type of common fish meat with an average taste.

[Claws: Hook-shaped parts on certain creatures, which are hard and sharp]

[Bonus Information: You have obtained the crafting recipe for the "Grappling Hook"!]

[Grapple: 1 grappling hook, 3 chains, requires an anvil]

[Note: Throwing a grappling hook can be used to climb rock walls or cross cracks, making it extremely useful in complex terrain.]

"There's such a good thing?"

Seeing the function of the "grappling hook," Lin You's eyes lit up.

Although he has two mobility skills: "Gel Leap" and "Spore Charge".

However, it still falls short when faced with complex terrain.

The appearance of the grappling hook can take his exploration ability to the next level!

"Great stuff, I'll make it when I get back."

He put away the grappling hook and the fish meat, then turned and walked back to Qi Chuan's mine cart.

"Qi Chuan, bring some wood or charcoal."

"Alright, boss!"

Qi Chuan realized what he was planning to do, so he quickly took out some wood from the box and made a campfire.

Lin You threaded the piranha meat onto a crossbow bolt, placed it over the campfire, and slowly turned it over.

The fish was quickly grilled until golden brown, with oil dripping down and a fragrant aroma filling the air.

Qi Chuan leaned against the car door, watching this scene, and sniffed.

"It smells so good... No wonder he's a master; even his grilled fish is amazing!"

"There's no need for flattery at times like this."

Lin You handed him a skewer of fish, feeling both amused and exasperated.

"Try it."

Qi Chuan took it, took a bite, his eyes widened instantly, and he began to wolf it down.

Even without any seasoning, it still tastes much better than eating insect meat dry.

Lin You was also leisurely enjoying the fish, occasionally stroking Yan Ling.

The two people and the cat quickly devoured all the piranha's flesh.

"I have to go now."

Lin You glanced at the time of her stay; less than three minutes had passed.

Qi Chuan stood up and bowed solemnly to Lin You.

"Boss, what happened today... I'll never forget it."

"Be careful, and let me know if anything happens. Don't be shy."

Lin You patted his shoulder, then transformed into a streak of light and disappeared underground.

Qi Chuan solemnly cupped his fists towards the spot where he had just stood, then let out a long sigh.

Looking back now... I sold that gold miner's ring to Lin You on an installment plan.

This was probably the most valuable investment he ever made in his life!

If it weren't for Lin You, he would probably already be on the forum's death list.

……

You have returned to "The Gold Digger".

After being teleported back, Lin You looked around and went to the metal processing table.

"The iron chain is made by processing iron ingots using a metalworking table."

"Three iron chains...that's enough."

"Then comes the anvil, which is made into a 'grappling hook' using a claw hook. Tsk, who came up with that name?"

[In production... Expected completion in 30 minutes]

"It will take quite a long time."

Lin You muttered something to herself and casually opened the forum for a quick glance.

As expected, the forum exploded again after the announcement of the escalating undead invasion.

In the gaming market, the price of silver ore and silver products that can suppress the undead has nearly tripled!

"Panic is the best catalyst for price increases."

He shook his head and was about to close the forum when a private message popped up.

[Elena: Mr. Lin, someone posted on the forum saying you killed his friend. Is that true?]
