Chapter 524: Dive! Half Heaven, Half Hell!

The Yongle Dragon Hole came into view, and the Qingfeng Cruise Ship sailed straight ahead.

Along the way, the ospreys resting on the sea made way one after another.

Seawater continuously slapped against the hull, splashing up bursts of white waves.

The Little Falcon soared in the sky, taking pleasure in chasing away seabirds.

Ning Fei had told it not to hunt birds randomly. The Little Falcon listened to him well, only occasionally chasing seagulls for fun.

From time to time, the Little Falcon would even fish up a few sea fish.

There had never been a shortage of food on Ning Fei's ship.

"From a scientific perspective, blue holes were formed when ice age karst caves collapsed into the seabed, much like a giant well."

"The seawater inside doesn't circulate, and the oxygen level is extremely low."

"Of course, there are also legends that a dragon once lived here, or that Sun Wukong pulled out the Sea-Calming Divine Needle from this spot."

"I'm going down this time to explore the true secrets of the Yongle Dragon Hole."

Ning Fei said.

"Temple Master Ning is so brave. I'm from North Island, and even the locals don't dare go near that place."

"What a coincidence, I'm from North Island too. They say that place can suck small fishing boats in. It's incredibly weird!"

"Why do you think the Government sealed off the Dragon Pit? It's because it's too bizarre, and they couldn't find the cause."

"Right. On one hand, it protects the fishermen, and on the other, it protects the natural ecology."

"That part is really strange. Other countries have blue holes too, but quite a few of them are open to the public."

The viewers discussed fervently.

"Still, be careful. Rumor has it around here that the Dragon Pit used to be a Dragon King Temple. Later, the Dragon King Temple collapsed, and with no one to protect this stretch of sea, people started avoiding it."

The netizen from North Island continued.

The Yongle Dragon Hole inherently possessed an air of mystery.

The Government's protection of this place was somewhat puzzling.

But now that Ning Fei wanted to explore the Yongle Dragon Hole, the relevant authorities had gladly agreed.

Ning Fei noticed several coast guard ships around the Yongle Dragon Hole. They had likely come to escort him for this exploration.

Ning Fei continued, "Blue holes are a major miracle of the ocean."

"The Yongle Dragon Hole is the deepest blue hole in the world, reaching a depth of over 300 meters."

"The second deepest blue hole is only 202 meters deep."

"This shows just how magical the Yongle Dragon Hole is."

The Qingfeng Cruise Ship drew closer and closer to the Yongle Dragon Hole.

The viewers saw that the water of the Yongle Dragon Hole was a dark blackish-blue, so deep the bottom couldn't be seen.

It looked exactly like an abyss.

Looking through the livestream camera, an oppressive feeling washed over them, making it somewhat hard to breathe.

Light blue and dark blackish-blue—the two colors were sharply distinct.

The color contrast made the Yongle Dragon Hole look like a pitch-black eye.

"That looks so scary!"

"For someone with claustrophobia like me, this is a nightmare!"

"Government personnel have used instruments to explore this place before."

"But no one has ever actually gone down."

"According to the exploration results, there is no life at the bottom of the Yongle Dragon Hole because the seawater doesn't circulate, and the oxygen level is extremely low."

"And the most terrifying part is that there's a toxic hydrogen sulfide layer underwater, which completely blocks out oxygen."

Just as he was about to enter the waters of the Yongle Dragon Hole, Ning Fei stopped the Qingfeng Cruise Ship.

The Yongle Dragon Hole was surrounded by reef structures. Even at high tide, the water was only three meters deep.

The Qingfeng Cruise Ship couldn't sail over it.

Therefore, Ning Fei could only swim across.

"Next, I'm going to explore the deepest blue hole in the world!"

"I hope I can make some new discoveries."

Ning Fei released the Submarine Type B Bionic Tuna and the Submarine Type C Bionic Flying Fish entirely into the sea.

Then, he put on his specially made Diving Suit, strapped on an oxygen tank and propulsion device, and dove into the water as well.

It was difficult even for a Submarine to dive in this place.

Floating on the surface, Ning Fei began to swim forward.

Right then, two middle-aged men in diving suits suddenly surfaced from the water.

"Temple Master Ning, we are divers from the Sansha City Geological Bureau, here to escort you!"

"Temple Master Ning, higher-ups place a lot of importance on your exploration this time."

The two men said one after the other.

Ning Fei hadn't expected the authorities to make such an arrangement.

This counted as a security measure.

Although it wasn't of much use, because other than Ning Fei, no one else dared to go down.

"Thanks!"

Ning Fei waved at them to express his gratitude, then continued forward.

The drone flew high up, filming from a bird's-eye view.

The viewers watched a figure swim from the light blue waters into the blackish-blue section.

Ning Fei kept swimming, gliding over the very top of the abyss.

The scene was exceptionally spectacular and awe-inspiring.

It left everyone watching absolutely breathless.

"I'm going to start my dive now."

"I wonder if there really is a dragon inside the Yongle Dragon Hole!"

Ning Fei joked, significantly lightening the mood in the livestream.

Anything was possible.

There were millions of life forms in the ocean, far more than the animals on land.

The marine life known to humanity was merely a fraction.

And a blue hole like this had never been truly explored by a human diver.

Machine exploration alone might not yield the true answers.

Ning Fei dove downward.

The moment he went under, the entire world fell silent.

Through the drone, the viewers saw Ning Fei completely disappear into the massive dark blue sea.

While everyone was exclaiming in shock, the livestream camera switched to the Bionic Tuna.

At this moment, the sun was shining high in the sky.

Logically speaking, underwater visibility within two hundred meters should be very high.

However, this wasn't the case in the claustrophobic blue hole.

At first, the seawater was still clear and transparent, as it was just the surface water, still part of the greater sea.

He could even see a few common sea fish and a lost little moray eel.

The surrounding walls were covered with colorful coral.

As Ning Fei continued deeper, the screen suddenly went pitch black.

The netizens could feel that this darkness wasn't just because the light couldn't reach it. Instead, the seawater here was a deep blue, and layered together, it appeared intensely black.

"What happened? Who turned off the lights?"

"Holy crap, how did the water turn black!"

"What exactly is going on? It looked fine just a moment ago, but it suddenly feels so oppressive!"

The viewers continuously asked questions.

Although Ning Fei couldn't see the chat, he still explained, "I have already passed through the hydrogen sulfide layer."

"Because the water deep inside the dragon hole lacks oxygen, anaerobic bacteria breed here, releasing massive amounts of hydrogen sulfide. On one hand, this isolates the oxygen; on the other, it turns the water black."

"This is also the most terrifying aspect of the dragon hole."

The netizens looked through the livestream camera.

Above the hydrogen sulfide layer, many sea fish were still swimming freely, and the walls were adorned with brilliant coral.

Beneath the hydrogen sulfide, everything turned pitch black. There was no life, no movement, like a dead sea.

No one could have imagined such a drastic change occurring within the same body of water.

Half hell, half heaven.

Right at that moment, the System's voice rang out on cue.

"Ding! Detected that the host has successfully checked in at the Yongle Dragon Hole. Reward: Top-Tier Rare Species (Divine Beast) Location Card."

"Ding! Detected a top-tier rare species (divine beast) in the vicinity. Triggering quest: Explore the Secrets of Yongle Dragon Hole."

The System's first notification was within Ning Fei's expectations.

However, the second notification truly took him by surprise.

"Is there really a divine beast in this dragon hole?!"
