"Jarvis, we're ready to enter the Blue Hole."

Headway tugged at the rope around his waist to make sure he and Leno were firmly attached:

"Don't forget the undercurrents I said. The roads inside the Blue Grotto are intricate, and undercurrents are everywhere. If you encounter an undercurrent, you must hold on tightly to the rope and never be swept away. ”

Headway patted his head as he spoke:

"Oh, by the way, you know the spell 'Deep Sea Swim', so you can practice it in the Blue Hole. The sooner you become familiar with this spell, the less dangerous you will be to encounter an undercurrent. ”

"Okay, I'll try." Li Nuo sketched out the blueprint of the spell of "Deep Sea Swimming" in his mind.

A dark blue spell glow appeared on his body.

The brightness of the light changed from strong to weak, and then to a thin blue film of water attached to the surface of his body.

"Deep Sea Swimming" was cast.

Li Nuo raised his arm and waved it a few times in the water, with some joy in his eyes:

"This spell is really good, Headway, no wonder it is a must-learn for every deep-sea wizard. I felt that my movements were much smoother, and the resistance of the water became very weak. ”

Headway looked at Li Nuo's free spell casting, shook his head and sighed:

"Your magical talent is truly enviable. Be careful, though, as the "Deep Sea Swimming" spell can't completely cancel out the impact of the undercurrent, at most it will give you more room to maneuver and not be swept away by the undercurrent all at once. ”

He waved his hand and said:

"Alright, let's go into the Blue Hole. It's almost nine o'clock in the morning, and we can stay in the blue hole until five o'clock in the afternoon. These eight hours were enough time for us to hunt for treasure in the cave. ”

Headway squirted a stream of water from his back and dragged Leno towards the hole.

This deep-sea wizard with the strength of the five rings has never been aware of the Dark Tide spy who is peeping in secret.

The entrance to the Blue Hole below is an irregular circle, more than ten meters in diameter, with uneven edges, a bit like the giant mouth of a monster under the sea.

The closer you get to the entrance of the cave, the more oppressive this underwater landscape becomes, enough to make people with a phobia of deep-sea giants attack.

Li Nuo didn't feel any discomfort.

He doesn't have a phobia of giants, that's one thing.

Second, the entrance to the cave was filled with blue light, and the moss more than half a meter high illuminated the entire cave. From the entrance of the cave to more than 100 meters deep, it is all bright, and there is no dark area.

With such light conditions, there is naturally nothing to be afraid of.

Headway throws a "secondary bathyscopy" into the cavern to look for possible dangers in the road ahead.

"Deep Sea Exploration" is a high-level spell that can detect the surrounding sea water in all directions.

"Secondary Deep-Sea Exploration" is a regular spell that can only detect seawater in a specific direction.

Li Nuo mastered "deep-sea exploration", not "secondary deep-sea exploration" of Hideaway.

When he saw Headway's cautious appearance, he knew that he didn't need to worry about the safety of the road ahead.

On the contrary, it was the dark tide spy hiding outside the cave, and he needed to pay more attention to himself.

Li Nuo threw out the "Psychic Beacon" at the entrance of the cave and opened the "Psychic Horizon".

The magical vision unfolded before Leno's eyes, and Haidway, who was swimming ahead, did not react.

Leno nodded secretly, making sure that his mind magic would not be detected by Hideway.

In his magical vision, he threw out several "Psychic Beacons" again, and with the help of the "Psychic Vision" "Vision Jump" feature, he found the Dark Tide Spy lurking in the shadows.

At the very moment when Leno followed Headway into the hole, the Dark Tide Spy followed in a silent manner.

The scales on his body have a nice camouflage effect, and seem to change color automatically according to the environment.

If it weren't for Li Nuo's activation of "Perception Enhancement" and the deconstruction technique in his hands, it would have been almost impossible for him to discover this dark tide spy who blends in with the environment.

Li Nuo saw that this guy was following the two of him with bad intentions, so he didn't bother to deal with the other party, and directly launched a "mind bombardment".

The invisible Dark Tide Spy stopped in place without warning. His body twitched violently, stirring up the sea and rolling up puffs of white sand.

"Gurgling, gurgling...", the sea is churning.

"Poof~" The Dark Tide spy broke out of invisibility, his head exploded, and the red and white things wandered along the sea.

Headway stopped in confusion and looked behind him warily:

"Huh? Strangely, I seem to hear unusual fluctuations in the sea. ”

"What fluctuations?" Li Nuo pretended to be confused and looked out of the cave with the other party.

Headway scratched his head:

"Maybe there's a big fish passing by, let's leave it alone."

Headway continued to jet water, dragging Leno deeper into the cavern, focusing on the tunnels ahead.

Li Nuo looked at the magical vision in his mind and threw the "Death Technique" towards the headless corpse that was floating upward.

The headless Dark Tide Spy twitched a few times in the water, swimming into the distance in a stiff stance, leaving a trail of blood-colored mist.

After the Darktide Spy moved away from the cave where the two of them were, Li Nuo called up the spell list and upgraded the "Evil Explosion Technique" to level 5.

In this way, he will be able to unleash the "Evil Explosion Technique" on the corpses of the Darktide Spy's level 5.

"Bang~~" The headless corpse of the Dark Tide spy was detonated by Li Nuo.

The ripples of the sea water set off by the explosion spread thousands of meters away, turning into a dull buzzing vibration.

Headway has entered the Blue Grotto at this moment, and it is about 20 meters away from the entrance of the hole.

He vaguely sensed the fluctuations in the sea caused by the self-explosion of the corpse, glanced back, and asked:

"Jarvis, did there just an explosion outside? Have you ever felt a less noticeable fluctuation in energy? ”

Li Nuo shook his head:

"Nope."

Headway scratched at his liquid beard:

"Okay. It looked like it was my first time taking someone into the Blue Hole, and I was a little too nervous. ”

Headway maintained the current behind him and led Lino through the cave.

Their figures were quickly obscured by a dense blue moss and disappeared behind the first corner.

Li Nuo looked back at the entrance of the cave that was covered by the cave wall, and smiled secretly in his heart, he could figure out the perception range of the five-ring deep-sea wizard in the seawater.

There's nothing wrong with increasing the "Spirit" stat value to increase the range of energy perception.

However, in the seawater, all wizards will have a significant reduction in the range of energy perception due to the change in the medium of energy transmission.

Headway is a prime example.

The results of the deconstruction show that his "spirit" is 160 points, and the range of energy perception on land is 1550 meters.

When underwater, without the help of "secondary deep-sea exploration", his perception range will be reduced to 200 meters.

The "Evil Explosion Technique" that Li Nuo had just triggered was almost two hundred meters away from Headway's straight-line distance, which was exactly at the limit of Headway's perception range.

Hedaway had the illusion of whether there had been an explosion just now.

"My energy perception range has also been weakened by the deep-sea environment, but I have the "Psychic Beacon" and "Psychic Vision", and I can still use my magic vision to accurately lock on to the target of the spell. In this way, the high-level spell of "Deep Sea Exploration" is more valuable than I expected. Only a deep sea wizard with this spell can have an energy perception range comparable to that on the water underwater. ”

Li Nuo gave a thumbs up to "deep-sea exploration" in his heart.

He searched his magical vision, but found no other Darktide Spies.

That's right, according to the "Surveillance Plan" deconstructed from the Darktide Spy Vasdagan, during the day, there is and only one Darktide Spy, Vastagan, guarding the Mossy Blue Hole.

In the evening, another Darktide spy will come to take over the shift, spying on the Flooded Blue Cave in Vasdagan's place.

The Horror Pirate Nation only knows that there is a group of mermaids near the Rainbow Blue Hole, but it is not clear where this group of mermen is located.

Two Dark Tide spies work in two shifts here in the Blue Cave, monitoring the entrance of the cave 24 hours a day, just to find out the group of mermen.

About a week ago, on the day Leno slaughtered Dikla Fagan's personal butler, the Channar family's maritime patrol wizards spotted traces of the mermaid in the Mossy Blue Cave during a routine inspection of the seabed.

It was night, and the lighting conditions were not good, and the wizards of the Chanar family could not be sure if the information was accurate, but they still reported it to the head of the family.

This news was eventually overheard by the Dark Tide spies lurking in the Channar family, hence the current surveillance operation

Judging only from the results of Li Nuo's deconstruction...

The number of dark tide spies in the Channar family is really not ordinary.

But the situation of the Chanal family is different from that of the Pangula family.

Dikra Fagan Pangula took the initiative to seek cooperation with the Sail Pirate State.

As a wizard family that started as a trader, the Channar family hated illegal professions such as pirates and spies, and only had the idea of killing the Sail Pirate Nation as soon as possible.

The Sail Pirate Nation planted spies in the Channar family in order to obtain first-hand trade information and accurately plunder the trade fleets in the deep sea.

When Li Nuo handled the bounty task with great efficiency before, he had helped the Channar family find out a lot of spies, and was warmly welcomed by the Channar family.

Later, because Leno was too wild and uninhibited when he sabotaged Dikla Fagan's dinner, the local manager of the Chanar family was cautious and postponed the meeting with Lino.

To this day, Leno has yet to meet with the local head of the Chanar family.

The manager, Rappe Channar, was the first in line to the throne and head of the Channar family, and personally managed the Suman Islands, the most important transportation hub for deep-sea trade.

Befriending Rape Chanar was part of Lenovo's plan to take control of the Suman Islands.

In the case that he has already eliminated a dark tide spy who is monitoring the blue hole, Li Nuo is ready to follow this clue and refer to the "Surveillance Plan" to clean up all the dark tide spies related to the blue hole.

This operation should be regarded as a big gift to Lape Chanal when he meets him in the future.

Li Nuo made a plan of action in his mind, and then fixed his mind, closed the "Psychic Vision", and dispersed the magical vision of observing the blue hole.

He turned his attention to the cave he was in.

Headway led him through several turns in succession, from going vertically down into the cavern to swimming horizontally down the rugged tunnel.

The floor of the tunnel is jagged, and the slippery stones are covered with blue moss.

In the moss here, Li Nuo saw many dragon relics that had been soaked in the sea and blackened.

Due to the poor condition and the fact that he could not provide much energy, Li Nuo did not beckon Hedway to stop and let himself take a closer look at what was on the ground.

On the walls on either side of the tunnel, there are narrow black openings or twisted gaps every few meters.

Li Nuo activated "Life and Death Tracking" and glanced at these dark areas.

He saw some of the young sea snakes that inhabited it, but he did not see the larger sea snakes.

It's kind of weird.

Li Nuo asked Hedway, and the other party didn't know why, only mentioning that as long as the two of them didn't enter the dark area, they wouldn't be attacked by sea snakes.

Seeing that Headway didn't care much about the fact that there were only young sea snakes in the dark area, Li Nuo put this strange phenomenon behind him.

When the two arrived at a fork in the road, a turbulent undercurrent came out of nowhere, brushed past Li Nuo, and rushed to the passage on the other side of the fork.

Two jets of water shot from under Haidway's feet, carrying Leno out of the undercurrent, leaving the churning waters behind.

"Fortunately, you can also use the spell of "Deep Sea Swimming", and the resistance of the undercurrent is minimized by you, otherwise it will take a lot of magic to drag you out of the undercurrent."

Headway turned around and muttered a few words to Lino and continued to swim ahead.

The further you go, the more dragon relics are scattered on the ground.

After experiencing several undercurrent "sneak attacks" again, the two finally arrived at the huge cave that was rumored to have many dragon collections.

As described by Headway, this place covers a vast area, with a visual width of more than 500 meters and a height of more than 20 meters, making it a well-deserved large cave.

There are several low mountains five or six meters high on the ground, all of which are dragon collections that have been brought here by the undercurrent.

When Li Nuo arrived here, there happened to be a strong undercurrent passing through the cave.

This undercurrent rolled up most of the low mountains on the ground, causing the dragon collection to flutter around like a goddess scattering flowers.

It took a full three minutes for the dragon collection floating in the water to slowly fall, reforming into a few low mountains and a carpet covering the ground.

"We're here, Jarvis." Headway pulled out a few metal spikes with thick bowl mouths from his magic pocket:

"I first drove these nails into the rock walls of the cave, they are our important insurance against the undercurrent. When you're searching for a collection, make sure that the ropes around your waist are connected to the metal nails so that you don't get swept away by the undercurrents here. As you saw just now, the undercurrent in this place is much more ferocious than what we have encountered before, and no one knows how it appears. ”

With a few words, Headway pulled out his hammer and began to secure the metal nails to the wall with a clanging crunch.

Li Nuo had nothing to do, observing the surroundings.

The undercurrent just now rushed in from the hole in the depths of the cave.

There was no moss-blue glow in the hole, it was pitch black and a little creepy.

The rest of the cave is not very well lit, with only a few places with blue moss.

Deconstruction followed Li Nuo's gaze and swept across the cavern.

[System News:]

[You are about to deconstruct the "Rusty Anchor."] 】

[You are about to deconstruct the "greenish silverware.] 】

[You are about to start destructuring "rotten metal objects.] 】

[You're about to start deconstructing the "Unexplained Dragon Tools"]

…

Lines of systematic text refresh in my mind.

In general, about one out of every four things is directly related to the dragons.

For this journey, Li Nuo prepared five large-capacity underwater special magic bags.

This magic pocket can be used underwater, so you don't have to worry about seawater filling into your pocket while storing your belongings.

These five pockets will be used by Li Nuo to carry things that are small in size and have a high energy reserve.

If something is relatively large, Li Nuo plans to destroy it on the spot, using passive deconstruction to get the energy reward in his hands.

Like that metal cabinet.

The name given to it by Deconstruction is "Dragons of Unknown Purpose", and the cost of deconstruction is 100,000 energy.

It is relatively large, two meters tall and one meter wide, with heavy metal door panels, and is one of the few heavy things that has not been swept by ocean currents.

Such things are old and heavy, and it is not easy to fit in a magic pocket.

Destroying the scene is the best choice for Li Nuo.

Li Nuo's eyes fell on this cupboard-like thing, remembered its position, and planned to smash it in a moment.

"Boom..."

A slight crash came from the cabinet that Li Nuo was staring at.

This sound was mixed with the movement of Headway hitting the metal nail, which was not very obvious, but it was noticed by Li Nuo, who had turned on the "enhanced perception".

Li Nuo couldn't help but be stunned.

"Knock, knock, knock..."

A series of crashing sounds rang out in the cavern.

Headway stopped what he was doing, scanned the cavern in confusion, and finally looked at the large metal "cupboard" with Lenovo.

"Uh, Jarvis, do you hear the knock knock? It seems to have come out of that dragon's nail box. Headway said with some uncertainty.

"Nail box?" Li Nuo asked.

Headway pointed to "Cabinet":

"Well, that's the metal cabinet you see now. It was a bit like a cupboard for us, but in the Dragon Age, it was the thing that dragons used to store their nails, and there were usually nail clippings cut from the dragon's claws. ”

"Knock knock..."

After hearing the sound of the two of them communicating with each other, the contents of the nail box tapped the metal cover at a faster frequency, as if trying to get out of it.

Li Nuo and Headway glanced at each other, shook their heads slightly, and said:

"My 'life and death tracker' told me that there were no living people, dead bodies, or undead in the nail box, and I didn't know what was hitting the lid."

Headway was about to speak, but Li Nuo interrupted him by raising his hand and staring at the nail box.

"Wait, Headway. I see what's in the box. It was a merman. It disables some kind of magic that shields detection, and I didn't see it in my magical vision until now... It seems to be asking us for help. ”

"Shark??" Headway's eyes widened:

"Are you sure? Could it be a Kraken? Both the Kraken and the Shark have tails, one like a snake and the other like a fish. ”

"Sure. I can't be mistaken, it's a mermaid with a fishtail, not a kraken. Li Nuo nodded calmly.

In his magical vision, he saw a small merman with a fishtail.

The information fed back by deconstruction also proves that Li Nuo did not look away.

[System News:]

[You are about to launch a deconstruction technique against the "Unknown Female Mermaid.] 】

[It is estimated that 70,000 energy points will be consumed, which can make the completion of deconstruction reach 100%]

70,000 deconstruction costs, which is comparable to deconstructing the Wizard of the Four Rings.

For the time being, Li Nuo regarded the female merman locked in the nail box as the strength of the four-ring deep-sea wizard.

Seeing that Leno was so sure, Headway stretched out his right hand towards the clattering nail box.

His palm stretched outward, turning into several streams of water, and from a distance of tens of meters, he touched the top cover of the nail box.

After fumbling around the sides of the lid a few times, Headway relied on his research into the dragon collection and managed to unlock the mechanical lock on the outside of the lid.

"Smack." The latch opens.

A petite pink figure crashed out of it, staring at Li Nuo and the others with teary eyes.

"It's really a merman. Her skin and scales are pink and she is very small. Headway thought for a moment and said:

"This should be a female mermaid who has not yet reached adulthood, which is equivalent to a fourteen or fifteen-year-old girl in us humans. How could she be here alone, still locked up in a nail box? … It's really confusing to me. ”

"Yaya~yaya~" The female mermaid shouted a few times at Hideway, and swam over without flinching.

Li Nuo looked sideways at the big man next to him and said:

"How do I feel that this mermaid knows you?"

Headway scratched at his liquid beard:

"I feel that way, too. But I don't have any shark friends, so how can she know me..."

Headway didn't know what to remember, hammered his palm, looked at the female mermaid and said:

"Oh~~ I remember, you shouldn't be the merman baby who was put in a shell by the merman team two months ago, right?"

The female mermaid may have understood human language, or perhaps she could have read Hideaway's tone and expression.

Anyway, after Hedway's exclamation, she nodded her head again and again, and said a long "yaaaa

This was Hideaway's turn, he didn't know the language of the merman, and he couldn't understand what the other person was saying.

Li Nuo pondered for a moment and launched an all-round conventional deconstruction of the female merman.
