The fish finally succumbed to the temptation and slowly swam out. It opened its mouth and swallowed the sea urchin roe in one gulp. At the same time, the card in its mouth fell out.

Lu Fan reacted swiftly, like an agile ninja, darting through the water and catching the card in a single step.

He couldn't wait to flip open the card and take a look.

[Wilderness Survival Supplies Card]

Rare earth minerals (content 40 million tons)

The introduction focuses on a simple and straightforward approach.

Seeing that the card had no direct use for him, Lu Fan wasn't very interested, but he still handed it to An Lan with a smile.

"Rare earth minerals?!"

An Lan was extremely shocked to see that it was a rare earth mine.

Even without consciously seeking knowledge about it, she was well aware of the preciousness of rare earth minerals and understood their crucial role in national development.

The live stream chat instantly erupted in excitement.

"Rare earth mines!! We're going to be rich now."

"So what exactly is rare earth mining for?"

"You don't even know what rare earth mines are used for? You're finished! I'll tell you, I don't know either."

Upon seeing the comments, host Wang Tao quickly came out to explain.

Rare earth minerals are known as "industrial vitamins" and have a wide range of uses. First, in the metallurgical industry, they can optimize the properties of metals, making steel more tough and corrosion-resistant, and making aluminum-magnesium alloys more heat-resistant and fatigue-resistant.

In the aerospace industry, it is used to manufacture critical components, reducing weight while ensuring strength and reliability.

In the field of electronic information, rare earth elements are key raw materials for manufacturing materials such as liquid crystal displays, plasma displays, and fluorescent displays. For example, rare earth elements such as europium and terbium are used to manufacture colored phosphors, making the display screen more vibrant and the images clearer.

In the field of new energy…

Seeing An Lan's excited expression, Lu Fan became happy as well: "Take this supplies card for now. We'll release it when we get back to the shelter and find a safe and secluded place."

An Lan carefully placed the card in her pocket, a happy smile on her face, as if she had confiscated Lu Fan's salary card.

After calming down, the two continued exploring the mysterious underwater world.

Like two curious explorers, they looked around the seabed, and before they knew it, they had come to a place that resembled a cliff.

Below lies a bottomless abyss, so deep it seems to suck in one's very soul.

They also saw many huge stone pillars on the seabed. These pillars looked like toys left behind by ancient giants, standing in this deep and dark environment, exuding a mysterious and eerie atmosphere.

And in that pitch-black, almost opaque depth, there seemed to be a mysterious suction force trying to pull them down, giving them an inexplicable feeling of falling off a cliff.

Live broadcast room.

"Ugh, I think my thalassophobia is acting up, it's terrifying."

"Could those stone pillars represent some lost civilization?"

"It might be the work of aliens; the world is so big, who knows?"

Seeing the bizarre scene before them, Lu Fan and his companion couldn't help but get goosebumps, as if countless tiny ants were crawling all over them.

"Lu Fan, I feel like something's not right here. Let's get out of here quickly."

An Lan swallowed hard and said nervously, her voice trembling slightly.

Lu Fan nodded heavily, then tightly grasped An Lan's hand, preparing to retreat.

But fate always seems to play tricks on people, just when they were preparing to slip away.

[Sardine Storm Arrives]

Lu Fan turned around abruptly and saw a huge school of sardines surging in like a raging black tide, covering the sky and the earth.

The fish were so dense that they seemed to fill the entire seabed; their sheer size was awe-inspiring.

The two were instantly gripped by fear. Lu Fan felt his heart was about to jump out of his throat. Even though he was usually calm, he couldn't help but feel a sense of absurdity, as if the world was ending.

"Run!"

He shouted at the top of his lungs, his voice booming in the water, grabbed Anlan's hand, and swam backward with all his might.

He was in excellent physical condition and was as fast in the water as an antelope being stalked by a cheetah, so fast that he seemed to leave a faint afterimage behind him.

However, the sardines were so dense that they were still surrounded.

The sardines kept slamming into me, like a dense hail of bullets, hitting me painfully.

Lu Fan quickly pulled An Lan into his arms and waved his arms frantically, trying to drive away these annoying creatures.

Waves of sardines came one after another, seemingly endless, as if to drown them in this ocean of fish.

As he swam, he looked back and saw that the large fish behind him had transformed into a merciless killing machine, with its gaping maw capable of swallowing hundreds or even thousands of sardines in one gulp.

Water splashed everywhere, and sardines fled in terror. The entire underwater world seemed to have turned into a huge battlefield, a bloody and shocking scene that made one's scalp tingle.

In the chaos, a huge fish of unknown species charged towards them. It opened its mouth wide, and its sharp teeth gleamed coldly in the dim water, like blades.

Lu Fan's eyes widened, his heart leaped into his throat. He pulled An Lan with all his might, using the force of the water to dodge to the side, narrowly avoiding the attack of the big fish.

He then raised his trident and stabbed it directly at the big fish, which instantly felt pain and dodged.

The next second, the smell of blood attracted a higher-level predator, which tore the big fish to pieces.

Watch out behind you!

【left! 】

...

The Heavenly Dao notification sound flashed frantically, like an urgent alarm, constantly ringing in Lu Fan's ears.

Lu Fan used his trident to clear a path.

They dodged and weaved through the gaps in the school of fish, sometimes having to abruptly change direction to avoid a large fish that suddenly charged at them.

Their bodies brushed past the sharp coral, causing a ripple in the seawater, and the coral's spikes nearly pierced their skin.

After an unknown amount of time, the two finally escaped the danger zone, panting heavily in the water as if they had just walked through the gates of hell.

The trident in Lu Fan's hand has claimed countless fish lives.

"Thank you for your protection, Third Young Master. From today onwards, I will fight anyone who dares to speak ill of Third Young Master."

Live broadcast room.

"My God, we escaped! That was so dangerous!"

"I was in the bathroom just now and I was so scared when I saw this that I almost broke my arm."

"Really? Let me see."

"Ugh~"

An Lan patted her chest, her voice trembling with lingering fear: "That was terrifying, I was almost done for."

Lu Fan, panting heavily, said with a wry smile, "Yes, the seabed is much more dangerous than I thought."

At this point, the two noticed that they had less than half an hour left to explore.

【0:25:21】

An Lan looked worried: "Time is running out. It seems we won't be able to get back in time."

Lu Fan looked up at the light filtering through the sea, which was growing increasingly dim, and he felt extremely anxious.

Encountering the sardine swarm completely disrupted their plans. They were now too far from the sea, making it virtually impossible to return on time.

[A small island has been spotted to the left front]

In the gloomy environment, that small island was like a beacon of hope in the darkness, bringing them life.
