Conan and I start the hell-level main line

Thick fog filled the sea, like a layer of pure white veil. The thick white color enveloped the sky and the earth, and the vision was completely blocked by the fog, as if the space was only as big as the one in front of us.

The thick fog filled the sea, and a cold wind blew, which made the travelers on the river shiver. It was a kind of chill, but it did seem a bit eerie in the heavy fog.

The gloomy front may also be a warning, a warning of the unrest in the forbidden land.

A cruise ship appeared on the sea, sailing calmly out of the fog, blowing its whistle softly, with seagulls flying around it.

"Really? We finally got through that foggy area. It was so uncomfortable in there." Kogoro Mouri was smoking a cigarette, leaning on the railing, and said to the person next to him with some dissatisfaction.

"You have to thank me, you brat. You showed up so rashly and said you had to go to Fukui for a case. Just because I came with you doesn't mean I don't have anything else to do."

Osaka Black Chicken Hattori Heiji: "You don't have anything to lose. I'm paying for the travel expenses anyway."

"Okay, which island are we going to?"

"The island where mermaids live in the legend, Mermaid Island." Hattori Heiji leaned on the railing, facing the wind, looking at the tree-covered island in the distance and said.

"I also heard that there is an old lady living on that island who specializes in eating mermaid flesh in order to achieve immortality."

"I've heard of this too. You're talking about the old lady who caused a sensation three years ago because of her immortality." Xiaolan was followed by Kazuha, and she had some understanding of what Hattori Heiji was talking about.

"That's right, I just hope to be as young and beautiful as her, that's why I came along this time." He Ye also explained the purpose of his visit.

"I understand. Do you want to use your youth and beauty to tie Hattori down?" Xiaolan teased with an interested smile.

“Shh!!!” He Ye felt very embarrassed, so please don’t say what’s in your heart. . .

Conan smiled speechlessly, immortality, that's a bit far-fetched...

How can there be such a thing as immortality in this world? This is not a novel.

……

“Immortality may really exist.”

In the deep mountains of the Mermaid Island, Fu Huashi, Bian Che and Qin Lei traveled on the deserted path, struggling to pass through one mountain obstacle after another.

Fu Huashi: "Do you really believe what the longevity lady on Mermaid Island said? I believe in longevity, but immortality is too far-fetched..."

"Oh, you don't understand this. Everything is possible. Otherwise, why would the organization firmly believe in this mission?" Bian Che smiled and talked leisurely.

"Okay, brother, if you say it is true, then it is true." Fu Huashi did not refute. After all, if you want to ask, the nonsense about rejuvenation is true.

If you tell others about your idle time, they will immediately greet you with a healthy brain.

"Aren't we going to find a spring? Why are we still wandering around the mountain all morning?" Fu Huashi was walking fast and felt a little tired, so she asked Qin Lei who was following behind her.

"Um, ahem, the spring water is inside the Mermaid Waterfall, so we are going to find the Mermaid Waterfall now, right?" Qin Lei said with a somewhat embarrassed expression.

"Well, since this ghost waterfall has a name, it means it is an iconic place, so why do we have to go to the mountain to look for it aimlessly..."

"Could it be that you don't know where you are at all, or... you are lost..." Fu Huashi frowned as she looked at the two people in front and behind her.

Bianche and Qinlei looked very embarrassed and were sweating nervously, but they still said in unison, "No way!"

You are stunned, you must be lost! !

"Then how long will it take us to search!" Fu Huashi used a small knife to cut off the annoying branch next to her.

"Well, maybe one afternoon at the shortest, or two and a half days at the longest..."

Fu Huashi's mouth twitched, and she silently wanted to slap the sidecar leading the way.

"Then why don't we go find someone local to ask for directions instead of just going up the mountain without knowing where to go."

"Ah... that makes sense..." Bian Che was stunned. He had been in the organization for so long that he had forgotten about such things.

"Uh... But it seems like we can't get back to the village at the foot of the mountain for the time being..."

"Huh? Really? Then look at what this is." Fu Huashi kicked down a bush not far away, and a stone path repaired by people appeared in front of everyone.

Following the path, there is a village surrounded by small houses.

"Oh, why did we go down the mountain for no apparent reason..." The man on the sidecar looked at him blankly and said awkwardly and unnaturally.

Fu Hua Shi (ノ=Д=)ノ: "You really have led us lost!!!"

At this time, an old man happened to walk over without recognizing any relatives. Ah, he really randomly selected the lucky audience.

Fu Huashi immediately went up to greet him and asked, "Hello, uncle, where is the Mermaid Falls?"

The uncle was stunned, and carefully looked at the three people who seemed to be asking him for directions with ill intentions: "Are you from outside?"

"That's right, we are here to find the Mermaid Waterfall. Tell us where the waterfall is." Bianche said coldly with a commanding tone.

The uncle frowned instantly, "You two are dressed in black, and one of you is wearing a black robe. You don't look like good people at first glance. What bad things are you going to do to our Mermaid Waterfall!"

Huh? ??? Fu Huashi and Bian Che looked at each other in bewilderment. . .

"Hello sir, we are actually tourists who come here to participate in the Dugong Festival. We just want to visit the Mermaid Waterfall. Could you please give us some directions?" Qin Lei humbled herself, smiled bitterly, and pleaded in a compromising tone.

"Hmm? Foreign girl?" The uncle squinted his eyes and looked at Qin Lei's body carefully with lustful eyes. . . Not very big. .

"You are with these two guys who are obviously not good people. They must not be good people either. Moreover, they are foreigners. They must be here to steal our dugong arrows! I will never tell you the way!" The uncle said with a contemptuous attitude of resistance.

Huh? ? ? Qin Lei looked at the two guys who didn't look like good people speechlessly. They couldn't even say they were unreasonable.

"Um... let's ask someone else?"

"If a member of my organization is looked down upon by a useless old man, I will not be able to continue my career! If you don't take the soft approach, you will be forced to take the hard approach, right?"

The uncle took a step back suddenly, "What, you still want to fight?!" Looking at the young man in black robe, his face was completely gloomy and his brows were furrowed, and then he put on his half-baked fist and kick stance.

Ah Da~! "Do you know that I'm a black belt in Taekwondo? Come on, I'm not afraid of you!"

"Once I beat you up, I'll take you to the police station for free to sue you for rape... Ugh, you're just looking for trouble!"

The gloomy-faced sidecar in the hood was so angry that he laughed. He opened his eyes slightly and stared at him with a pair of cold gray eyes that seemed to exude death.

Sidecar took out a pocket watch from his pocket and swung it left and right in the air. The pointer on the pocket watch clicked, and it seemed that the only sound in the world was the turning gears.

“What are you going to do...ah..." The uncle's eyes quickly turned dim, and he stood there motionless like a walking corpse.

Bianche closed his eyes, threw away the pocket watch and held it in his hand, smiling coldly, "No matter what you can do, even if you know magic, you have to be hypnotized by me and let me do whatever I want."

Fu Huashi was a little stunned, and was hypnotized in an instant, this is too cool.

Sidecar snapped his fingers, "Don't bother asking, just lead the way."

"Yes... Master..." A voice without emotion or even soul came out of the uncle's mouth, and he walked ahead step by step like a puppet.

Bian Che smiled "sunny" again and walked over. Fu Huashi and Qin Lei looked at each other and hurried to follow.

The uncle walked stiffly in front, and he remained unmoved even when his face was scratched by a branch. It seemed as if his entire soul was stripped away, and he was just a mechanical puppet.

Soon, a towering waterfall appeared in front of everyone. The stream rushing down three thousand feet was so magnificent that people could not help but marvel at the wonders of nature.

"It seems we're here. We've done a good job." Bianche smiled and walked to the edge of the pool. The water was as reflective as a mirror and clear to the bottom. It seemed that the people here were well protected.

"Bianche, I actually really want to know why there is a legend about the immortality of mermaids on Mermaid Island." Fu Huashi said, looking at the spectacular waterfall.

"As for the so-called mermaids, Gin discovered here three years ago that this was just a lie made up by the people here. But as for immortality, maybe there really is a basis for it." Bianche touched his chin, thought, and snapped his fingers and gave an order.

"Is this your legend about immortality?"

"have.."

"Tell me quickly, what it is." Fu Huashi came over curiously.

"Legend has it that if you eat mermaid flesh, you will be immortal and forever young..."

"Stop!!! - You're answering the irrelevant question. I said it's not about mermaids!" Sidecar snapped his fingers again and said dissatisfiedly.

"have..."

"This should be what we want." Fu Huashi and Qin Lei looked at the dazed uncle and said.

"Legend has it that thousands of years ago, there was a tribe on Mermaid Island who held a secret of immortality. With this secret, the people of this tribe could live forever and remain young forever."

"Until one day, the heavens suddenly punished them. The lives of the people in this tribe began to wither quickly, and soon they died out. The secret of eternal life disappeared in the long river of time."

"A tribe from thousands of years ago? Extinction? What happened, collective food poisoning?" Fu Huashi used her imagination alone.

"Well, it's a good legend. Just listen to it as a story." Sidecar seemed somewhat satisfied and snapped his fingers. "Go back by yourself and forget all memories about us."

The uncle's eyes turned from gray to lifeless and dull. He walked back alone and quietly disappeared into the woods.

"Wow, I suddenly feel that hypnosis is so convenient. It can also make them tell their secrets effortlessly. It is much more effective than torturing them personally and using truth serum." Fu Huashi was moved from the bottom of her heart.

"Oh, you seem very interested~" Bianche came closer with his eyes narrowed playfully and smiled in a nasty way.

Fu Huashi laughed unnaturally, "Can you learn it? Will you teach me until I can do it?"

“Alas, this requires talent, and ordinary people can’t learn it.” Bianche waved his hand and chuckled.

"Also, since you mentioned secrets, hehe~Everyone who becomes an insider has his or her own secrets. Otherwise, tell me about it."

Fu Huashi (⊙▽⊙;): "Uh... Brother Bianche, you are kidding..."

"Hehe, no kidding. You have two choices. Either you say it out loud yourself, or I hypnotize you and you can say it out loud with peace of mind and without any embarrassment~" Bian Che grinned wickedly and slowly opened his grey eyes. There was a solemnity in the air and he even felt a little dizzy.

Fu Huashi was sweating profusely and felt that she was doomed. Suddenly, Qin Lei patted Fu Huashi on the shoulder.

"Don't be intimidated by him. The organization has long issued orders that this guy is not allowed to use hypnosis on code members unless it can be confirmed that there is a high degree of suspicion or approval from superiors." Qin Lei said lightly.

The man on the side squinted his eyes and smiled as if cursing someone. It's rare that I can scare people, please don't ruin my show. . .

Fu Hua Shi: Hehe... People with squinty eyes are all monsters...

"Okay, let's go over there. The spring is in the cave behind the waterfall. We just need to climb along the cliff and pass through the water to get in." Qin Lei said, pointing to the cliff in the middle of the waterfall.

Bianche and Fu Huashi nodded. It's just rock climbing. It won't be a problem for me.

Just as she was about to climb up the cliff, Fu Huashi suddenly seemed to sense something and turned back abruptly.

As a detective, he possesses a keen sixth sense similar to Conan. Just now, Fu Huashi vaguely felt that there were a pair of eyes watching them in the woods!

But when I turned around and looked carefully at the dark woods, there was no sound or trace, no insects or birds singing, everything seemed to be still, there was nothing.

Am I being overly vigilant?

"Hey, what are you still standing there for? Hurry up and catch up!" the sidecar urged.

"Oh." Forget it, Fu Huashi didn't care.

But when they all passed the waterfall step by step, a dark shadow slowly walked out from behind a shady tree.

Not far behind the black shadow, an old man with a ferocious face fell to the ground with a long bloody mark on his neck. The blood kept flowing out and dyed the ground red.

……

The cave behind the waterfall is not as exaggerated as the Water Curtain Cave, but it is also a dark tunnel.

But it is not long. At the end of the tunnel is a natural cave, which has a feeling similar to a cave. The smell is a mineral smell of stone and river water.

The cave is not big and has some fluorescence. Perhaps because it is not far from the waterfall, the light can still shine in, so you can still see clearly.

And in the center of the cave, there is a pool of blue spring water full of mystery.

"This is the spring we are looking for." Qin Lei stood in the front, looking at the spring that was said to give eternal life, and said seriously.

"Isn't it just a pool of cave water that looks very different? Why does it have such a magical effect of immortality?"

Qin Lei: "I'm not sure. There should be a substance in the spring water that can activate cell division, inhibit cell aging, and allow chromosomes to produce telomeres..."

"Stop, stop, stop! I don't understand at all..." This is the world of science, can we not talk about science?

"Okay, it doesn't matter if you don't understand. But I still have to remind you not to drink it, otherwise you will deserve to die." Qin Lei squatted down, took out a large water bottle from her bag, put it into the spring water and filled it up.

I know, I'm not that mean.

After filling it up, Qin Lei put the lid on, which even had a combination lock. The bottle was tightly sealed, and the safety factor was very high.

"Keep it safe and don't lose it." Qin Lei struggled to throw the big bottle full of water to Fu Huashi.

Bang! I’m so heavy!

Fu Huashi put the water bottle on her back with great difficulty, but the huge weight also made one of her shoulders seem to collapse.

Damn, I've become a water delivery man.

"Now that we have the spring water, we can go back now..." Fu Huashi said with difficulty.

I'm so heavy...

"It's still early. I still need to investigate this place, so we have to stay here for a few days." Qin Lei took out a notebook and said.

"So you're investigating now?"

"No, it's already afternoon, what's there to investigate? I heard there's an annual dugong festival tonight, and I can't miss the opportunity to watch the fun~" Qin Lei closed her notebook and said in a casual manner.

"Oh, okay..."

"Let's go eat some seafood. I heard that the seafood on Mermaid Island is especially delicious. I'm almost starving after climbing the mountain all morning." Qin Lei hummed a little tune and left.

Sidecar nodded in complete agreement and followed.

Fu Huashi was left behind, struggling to walk with an overweight water bottle on her back.

"Hey, Sidecar, let's take turns carrying it. It's really too heavy!!!" Fu Huashi said with all her might.

"Um..." Bian Che pretended to think and looked at Qin Lei with a smile, "Qin Lei, do you want to help..."

"I'm not helping you! A grown man wants a weak woman like me to do this kind of physical work. Aren't you ashamed?" Qin Lei said angrily.

"Yeah~" Fu Huashi said with a wicked smile.

Uh... Sidecar said who wants to do that!!! Anyone who wants to do that must be mentally ill.
