A string of blisters, emerging from the bottom of the lake, fluttered and burst on the surface of the water.

Sean and the others stood by the lake and waited.

In a short time, Harding emerged from beneath the surface of the Black Water Lake.

His face was slightly pale, probably because he had been in the water for too long, but to Sean and the others' surprise, Harding's eyebrows were already covered with a layer of frost. This proves that the water temperature in the depths of the bottom of Heishuize Lake is by no means as simple as minus thirty degrees, maybe it will be even lower, otherwise it is impossible to even affect a Saint Realm powerhouse like Hatting.

"How?" Sean asked.

"The edge around it is about three or four meters, but the more you dive towards the center of the lake, the deeper it will gradually deepen, and after swimming out of a hundred meters, it will reach a depth of about ten meters, but at this time it is still in a normal temperature state, and there is nothing strange around." Harding shook his head as he climbed up from the bottom of the lake, then reached out and patted off some of the ice chips, "It will take about 500 meters to swim before the depth of the lake reaches below 20 meters......

Speaking of this, Harding's gaze couldn't help but glance at Spector.

Sean keenly noticed this and couldn't help asking, "What's wrong?" ”

"Although the lake may seem very vast, based on my experience, it should be less than 3,000 meters long from east to west, and it is not easy to swim 500 meters without any assistance, especially for diving operations." Harding directly said the specific situation, "And. From our side, it didn't look like there were any patrols, but in fact, as soon as we swam five hundred meters, the Blackwater tribe's fishing boats began to fish on the lake. It's hard to lurk in the past without knowing it. ”

Even Harding said that it was difficult, so if you want to sneak to the bottom of the lake secretly, it is naturally not a simple matter.

It's just that after hearing Harding say this, Sean roughly understood what Harding's gaze at Spector just now meant. Obviously, even the powerhouses of the Sacred Realm found it tricky, but he, who was only at the pinnacle of the silver rank, was able to say it so easily, and summarized it before Sean and the others arrived. If it weren't for Sean knowing that Spectett's profession was a lurker, then he would have been suspicious.

Doubting whether Spector is hiding it. Or if there's some conspiracy or something.

At this point, Shaun or Harding can't be blamed for being suspicious, it can only be said that this is a common problem in the Miracle Continent. After all, the Void Realm is too important, and those enemies who have fought against Sean have finally discovered the importance of Sean's organization. Therefore, infiltration is naturally the only option they are imperative. But alas. So far, it has not been successful, after all, the gatekeepers are William and Elikate and Ruby, who are proficient in disguise and anti-tracking methods.

Of course, Sean did have some curiosity about Spector's origins.

Because judging by his speech and demeanor, this guy is obviously not a civilian or an orphan. It's just that because now is not the time to explore, Sean temporarily suppressed the doubts in his heart, and was ready to ask William or Ruby when he went back later, of course, if he could still remember.

"Oh, actually, I wanted to say it just now when you were diving." Spector apparently has a decent IQ. So when he heard Harding's words, he knew what was going on. "Well, I've been observing here for a long time, so I've found a safe way to sneak in, but I only have three chances to breathe along the way......" Spector took out a bamboo pipe from his body as he said this...... And you have to use this to ventilate. ”

Harding glanced at the object in Spector's hand, and then asked with some curiosity, "What is this?" ”

As a resident from the underworld, Harding's world has always been relatively straightforward in combat, although there are actions similar to assassination and beheading, but due to geographical environment and other factors, it is rarely necessary to use some side door props. Therefore, the act of using bamboo tube diving for ventilation like Spector is naturally incomprehensible to Harding, but after Spector's explanation, this guy quickly understands the purpose of this thing.

"With my ability, about 700 meters is basically the limit." "But my eyesight is actually pretty good, so I can still see roughly where the lake is, I don't know the specifics, but I think there seems to be an island." ”

"Island?" Sean was stunned for a moment, "Island in the middle of the lake? Why didn't you mention this in the intelligence feedback? ”

"Because I'm not sure either." Spector shook his head, "How to say it, because the distance is too far, and the surrounding environment is always patrolled by people from the Blackwater Tribe, and there is not much time for me to quietly observe, so I can't be sure." …… There are clear indicators in the intelligence feedback of the Void Realm, and all unconfirmed clues and intelligence are not allowed to be recorded, only information with definite evidence. ”

Speaking of this, Spector paused slightly before continuing: "Moreover, the Void Realm also has clear rules that must be reported every once in a while, so it can't be that I wait here until all the observations and investigations are clear before making a detailed report. …… However, I have already mentioned these clues in the secondary feedback, and the above agrees with me to continue my further investigation. ”

Although Sean didn't know how the Void Realm worked, he did know that the Void Realm did have multiple intelligence ratings.

Generally speaking, members of the Void Realm who are sent out to carry out missions must send back the mission target information with the highest priority, and the type of information that needs to be reported will naturally vary depending on the situation of the mission dispatch. For example, reconnaissance missions have information about the strength of the enemy's troops, the level of defense strongholds, the number of strong men, etc., and the most important prediction of enemy actions is not the task of the Void Realm, but will be analyzed and studied by the staff in charge of intelligence analysis after the information of the Void Realm is handed in.

Of course, reconnaissance missions like this occasionally feature a second army. Or when lurking in a certain city, you receive rumors that other powerful people have entered, etc. This information is secondary information that may or may not be relevant to the main mission. This type of information allows members of the Void Realm to make a rough description of the mission first, and wait until the above confirms or approves and re-instructs. Then conduct more detailed investigations and espionage.

"It's just that I didn't expect that someone from above would send someone over so soon." Spector continued, "And you're here in person, Lord Sean. ”

"Because here's what I need." Sean spoke.

When listening to Spector's report before, Sean had already found that it was probably not easy to get his hands on this holy demon bone, at least no matter how he looked at it, it didn't look like a strong person with a lower level of gold could start, according to the general system urine nature, then there were only two possibilities. The first is that this thing is really not an item that can be obtained at this stage. The second is that you need other means to get your hands on it.

If it weren't for the fact that there was a clear reference to the "Holy Demon Skeleton" in the manuscript many times, Sean would definitely choose to turn around and leave at this time, because since it is not something that can be obtained at this stage. Then there is no need to continue wasting time. Therefore, Sean guessed that the current situation should be the second situation, which means that he needs to use some other means to be able to get his hands on this holy demon bone.

Sean's first consideration at that time was the Pearl of the Deep.

This thing allows the player to gain the ability to dive regardless of water pressure and oxygen, if any. Then it is naturally easy to dive underwater. Merely. People are not as good as heaven, not to mention that he doesn't have the Pearl of the Deep on his body now, even if he really found the imitation of the Pearl of the Deep Sea that should have been stored on the Golden Knight's body in that stronghold of Mai En at that time, he may not really be able to enter here at this time.

Because, there is also a dungeon of the mermaid capital in the water demon vault, and according to the situation at the time, Sean will definitely choose to enter that underground city to explore.

So after all kinds of considerations, Sean let Harding dive into this black water first to see the situation.

"It's like there's a floating island." Seeing Sean's gaze on him, Harding nodded. "This floating island in the middle of the lake is about 30 meters deep into the water, and it looks like it is connected to the rock formations at the bottom of the lake. But in fact, there is still some distance between the lower end of the island and the bottom of the lake. …… However, I don't know the specifics, because 35 meters is my limit, and I guess I'll be very stressed. ”

"Did you see anything at the bottom of the lake?" Sean asked nervously.

As a demon descendant of the underworld, Harding has a very good ability to see darkly, so no matter how dark the bottom of the lake is, it will definitely be difficult for Harding. Although after hearing the descriptions of Harding and Spector, Sean had already guessed the general whereabouts of the Holy Demon Skeleton, but he was still a little unwilling, if the Holy Demon Skeleton was really deep at the bottom of the lake, then Sean could find some way to help Harding get through the last five meters or so of depth, so as to avoid a head-to-head confrontation with the Blackwater Tribe.

But it's a pity that this time even God didn't seem to help Sean.

"Nope." Harding shook his head, "I don't see anything other than danger at the bottom of that lake. …… If I had to say, there was probably a layer of mercury-like substance on the surface of the bottom of the lake, which looked black overall, but it had a silver texture, like blood vessels, and it looked a little disgusting. However, the surface volume of this layer of material is not small, almost in the range of about one meter in diameter. ”

"Active Abyssal Mercury." Hearing Harding's description, Sean knew what it was, "I see. ”

"What is that?" Harding and Spector asked, curious.

"The scope of the black water is so vast, and the further you dive to the bottom of the lake, the colder and more pressure it will become, and it is obvious that there must be something good at the bottom."

According to the game experience, the more dangerous things usually are, the better things will be, which has long been familiar to countless players in the game, so usually when adventuring if they encounter something strange or extremely dangerous, players will try their best to overcome it, and the purpose is naturally to take out the hidden treasures. It's just that these words, of course, Sean can't explain them too carefully to everyone. So it can only be explained a little bit in another way.

"I thought what I wanted should be at the bottom of the lake, but now I think it's on that floating island. I used to think that the people of the Blackwater tribe around me would row boats to the vicinity of the island in the middle of the lake every day, but now it seems that this is not the case at all. The real place for them to rest should be the island in the middle of the lake. Sean pursed his lips, his tone full of extreme dissatisfaction, "Now our biggest problem is how to enter that island in the middle of the lake without noticing." ”

"What is active abyssal mercury?" Spector saw that Sean didn't seem to have any intention of introducing such a thing, so he asked again.

"Abyssal mercury is a very special kind of dark substance." Sean glanced at Spector before explaining, "That's why this thing is special. It is because it has the corrosiveness and coldness of the abyss, and the toxicity of mercury. I guess the extreme coldness of the bottom of the lake is partly due to the mercury of the abyss, and judging by that. I am afraid that there is a lot of abyssal mercury at the bottom of this black water lake. ”

"This kind of thing is usually used as alchemy materials, but it can also be directly applied to weapons and equipment with special means, which can attach a certain amount of abyss resistance, poison resistance, or corrosive and erosive to the equipment, and the effect on dark creatures is not very obvious. But for normal creatures, it has a very considerable lethality. Sean paused. As if to give Spector a certain amount of time to digest his knowledge, he continued: "Active Abyssal Mercury means that this thing has not yet become solid. However, Active Abyssal Mercury is not suitable for forging weapons and armor, and can only be used for alchemy potions, because the toxicity of Active Abyss Mercury is extremely strong, and even a slight contact with the skin will cause very severe damage. ”

In the end, Sean thought about it. Then he said, "You know the Heart of the Abyss, right? ”

"Yes." Spector nodded, then replied solemnly. "Along with 'Whispers of the Revenant' and 'Potion of the Living Corpse', it is said to be the poison loved by the Assassins. Either one of these three poisons is ingested by mistake, and the only difference is that the death status is different. ”

Sean nodded and said, "Hmm." In fact, the main ingredient of the Abyssal Heart is three drops of active Abyssal Mercury. As for the other sub-materials, they are all things that can be replaced at will, anyway, this poison is basically incomprehensible, so there is no difference in what sub-materials are used, except for the three drops of abyssal mercury of the main material. ”

"Wow!" Spector looked at Sean with even more adoration, "Lord Sean, you are so knowledgeable!" ”

For such a compliment as Spector, Sean didn't say anything more. However, his heart completely lost interest in the bottom of this black water lake. If it was other treasures or something, Sean would have considered collecting them, but if it was abyssal mercury, then he wouldn't bother to collect them. Although this kind of thing is a very rare resource in the Miracle Continent, it is actually not very useful, not to mention that he doesn't know the main preparation method of the Abyss Heart, just collecting Abyss Mercury is a very troublesome behavior.

If you have time and have a mining method in the future, then you can come back to Kuromizuzawa.

The most important thing now is how to sneak into that island in the middle of the lake without alerting the Blackwater tribe.

After hearing Sean's words, the others also fell into deep thought, this question is obviously not easy. Based on the careful observations of Harding and Spector, it was concluded that they would have to dive for a distance of about 500 meters to reach the island in the middle of the lake, and at this distance there was absolutely no time for everyone to breathe. In fact, it is very dangerous to ventilate in the lake after swimming a distance of about 700 meters, because there are too many fishing boats in Kuromizuzawa.

Don't look at these people as if they were just fishermen on fishing boats, but for a tribe as famous as the Blackwater Tribe, everyone in their tribe is capable of fighting well. Maybe in the face of a strong person like Sean and others, there must not be much power to parry, but as long as Sean can't kill all the enemies in the first time, they will definitely sound the alarm, and the result will naturally be very troublesome at that time.

"Can we try to negotiate?" Heatley asked, tilting her head.

"Uh......" Sean looked at Seatli with a serious face, and finally made sure that she wasn't joking, so this made him really cry and laugh, "The Blackwater tribe is a tribe that believes in ancestors, and they don't believe in any gods. If it is other tribes that believe in gods, then we can also borrow the name of the goddess of life, but the Blackwater tribe has their own wizards and priests, and although the treatment methods are relatively simple and rude, they really don't need the help of the goddess of life. ”

"Or if you go and preach to them, I'm afraid they'll take you as a barbecue." Cecilia maliciously frightened Citri, and sure enough, the latter looked very frightened, and cursed in a low voice, "Damn barbarian", causing Cecilia to giggle.

Sean and Harding also showed a helpless wry smile.

"Perhaps, you can try disguise?" Spector spoke, "I found out before that the Blackwater Tribe is not a completely closed tribe, and they will also trade with some people, but their behavior is very hidden. If we can infiltrate the Blackwater Tribe, then I'm sure we can steal a fishing boat, so we can at least use the fishing boat to operate in stealth and sneak closer to the island in the middle of the lake. …… With our strength, as long as we can change our breath once, it shouldn't be a problem to dive for three or four hundred meters, right? ”

"I can't." Heatley shook her head immediately, "Don't say anything about ventilation and diving, I can't even swim." ”

"Neither will I." Cecilia also looked like a matter of course.

So Spector could only shrug his shoulders.

"No, it might work." Sean's eyes suddenly lit up, "If we can get a fishing boat, then we may not need to dive and can directly approach the island in the middle of the lake, after all, those guys around the island in the middle of the lake will definitely have to return to rest." ”

"However, the fishing boats are different from those boats on the island in the middle of the lake." Spector said with a puzzled expression, "If our fishing boat approaches, I'm afraid it will be discovered at the first time." Unless we can ......"

At this point, Spector was stunned, because he obviously understood the meaning of Sean's plan.

"Got it?" Sean smiled.

"I see." Spector breathed a sigh of relief, "It's worthy of Lord Sean, the strategy is really powerful." ”

Hearing Spector compliment himself again, Sean suddenly felt a little painful, because this kind of thing is not a strategy at all, it is just a normal plan of action, and even Spector himself can sort out his thoughts in an instant. Sean believes that as long as he is not stupid as a pig, he will definitely know what he means.

"What are you talking about?" Harding asked with a blank expression.

"Uh......" Sean seemed to think that it was not as simple as an egg pain, and he began to wonder, is he insulting the pig? (To be continued......)
