On the southeast coast, in the country of waves, there are countless legends such as sea owners, mermaids, and sea monsters.

Except for a few that are true, most of them are false rumors.

Every year, Konoha Village receives a similar commission.

The mountain spirit sea monster that is regarded as the target of the mission is most likely mistaken by the local villagers who have not seen much.

Occasionally, there will be people with ill intentions, pretending to be ghosts and fooling the people, so as to seek benefits.

At the beginning, Baiyun Yeshan didn't take this task very seriously, and only regarded it as a test to test the comprehensive ability of his subordinates.

After arriving in the country of waves and contacting the mission client, the Konoha ninja and his party launched an investigation according to the clues.

In fact, it did develop according to the things that led the team to Shinobi, until the four of them met an old man who called himself Urashima Taro, and the style of painting changed.

"You said that you were a person hundreds of years ago, saved a sea turtle, the other party reciprocated the favor, and invited you to go to the Dragon Palace to enjoy the blessings, because you were homesick, you went ashore to visit relatives, and found that a few days under the sea, hundreds of years have passed in the world, and you opened the treasure chest that is absolutely unopenable, and the white smoke that came out of it turned into what it is now?"

Hundreds of years ago?

No one in the ninja world knew what it was like at that time.

Not to mention hundreds of years ago, decades ago, it is not very clear.

Before the establishment of the order of one village and one country, there were few reliable history books handed down in the turbulent ninja world.

Perhaps only in the private collections of the Daimyo of the Land of Fire and the Furusugi family are still recorded in a few words.

In Konoha Village, there is very little information about this.

The relatively honest Yayoi asked sympathetically about the customs of hundreds of years ago, but Konishi was not convinced at all.

"Shiro, you think he's bragging, too! Hundreds of years ago, I really dared to blow! If you say a few decades ago, maybe you can still find some evidence, but what happened hundreds of years ago, you didn't say it?"

"Maybe!"

Since arriving in the country of waves, Bai's heart seems to be clouded, and he always feels a sense of being calculated.

"It's not dry, it's not brittle, it's boring! Mr. Hayama, you won't believe it, will you?"

"It's hard to say!"

From the perspective of a senior ninja, the old man in front of him, who called himself Taro Urashima, was too normal in terms of facial expression and emotion, and there was no trace of falsification at all.

Although there is no mind-reading skill of the mountain clan, Baiyunye Mountain, who has studied torture, can roughly judge some clues.

Especially a weak person like Taro Urashima, who doesn't have any strength to support him, can't hide his true thoughts at all.

"We're here to investigate the legend of the merfolk who can bring disaster to people, and we don't know this ...... Is there anything you can reveal?"

"Merfolk?"

Urashima Taro raised his head, opened his cloudy eyes, and made a memory,

"It's just a poor bunch of people, and in Ryugu Castle, the goddess and the local residents don't like them very much. If you want to turn to the humans on the continent, you will only be killed as monsters. There are also some bad sailors with quirks, who think that if they eat the flesh of a mermaid, they can live forever. It's all fake, but a lot of merfolk have died because of it."

"Merfolk, is it real? I thought they were all weird stories......

Shiro asked naturally,

"Have you seen them, and where?"

"When a mermaid and a man meet, either the former is eaten or the latter is killed. Everyone...... It's all too ignorant, they can get along in harmony, but they kill endlessly. Now, it's hard to find! The surviving mermaids basically don't leave Dragon Palace City, and even if they occasionally appear, they are either hidden in the market, no different from people, or they hide far away."

"Just tell us the place."

Baiyun Yeshan said,

"We're not uninformed fishermen, we're ninjas who have been specially trained to see everything and won't hurt them."

"In the past, there were also people like you who were ashamed to go to the Dragon Palace

The city searched for mermaids, and the result was ......."

"How's it going?"

"Not a single one came back! The mermaid is not easy to deal with, and the Dragon Palace has no return......

"Are the people there, dangerous, strong, bad?"

"It's hard to say! Or maybe after I went, stayed for a few days, and came back hundreds of years later, like me, I was considered dead, and when I reappeared, I became a crazy old man, or I simply turned to dust."

Next, the four Konoha ninjas chatted with Urashima Taro for a long time, obtained a lot of information, and finally got the key address.

"Take a break, tomorrow, go to that place."

"Wait, Mr. Hayama, I always feel that something is wrong. If Ryugu Castle is real, why has it never been heard of before? I've been in the Gushan family for all these years, and I've heard some similar stories, but they've never been confirmed."

"Is it possible that you came late and knew less? Maybe Xiang Ryu will know ......."

"No, no, no, Mr. Hayama, I don't know about Kao-chan!"

Yayoi, who joined two years earlier than Shiro, added,

"I've never heard her talk about anything like it!"

If something happened on the southeast coast that even the Gushan family didn't know, it would be very troublesome.

"Is it possible that it has something to do with the Furusugi family?"

Bai Yunye Shan guessed casually, but after pondering for a moment, he couldn't help but deny the idea.

[The app that has been running stably for many years is comparable to the old version of the book-chasing artifact, which is used by old bookworms.]

Come, who comes! As for the location, as I just said, this is Zuodu Island, and the foot can be called Zuodu Town. The last time I had an uninvited guest, I can't remember when it was."

"We weren't here before, and in the blink of an eye, we suddenly appeared in your land, I don't know what the mayor has to do?"

Bai Yunye Shan asked politely about the ins and outs of the situation.

"Taro Urashima? I don't know! However, the mermaid and Ryugu Castle ......."

"You know? Please give me advice!"

"Then you are asking the right person, the other villagers don't know, I still know a little bit about it."

Shiranui smiled mysteriously at first sight,

"Actually, the local villagers are said to be the descendants of the residents of Ryugu Castle, and some of them have inherited the mermaid bloodline. What kind of mermaid's meat will never grow old after eating, it is all a rumor spread by falsehood. The merfolk themselves are a race with a shorter lifespan than normal people, how can their flesh and blood have the function of making people immortal?"

"Have you ever seen a merfolk?"

"When I was a child, I was lucky enough to see it! It was a great festival that people will never forget, and the dense mermaids on the sea were truly spectacular."

Several people talked for a long time one after another, and when they saw the half-truth, they also revealed a lot of necessary information.

"It seems that the mayor knows a lot about the outside world!"

"Of course! There are quite a few things that the mayor can come into contact with, and there are not only one or two outsiders who have strayed into this place."

"Where are those people now?"

"Some of them are tired of the deceit of the outside world, so they settle here and grow old here, some of them go to find Dragon Palace City and mermaids, and the rest spend their days wondering how to go back......

"Can you go back?"

"Of course you can, if you can come, you can go back! The Urashima Taro you saw was most likely stumbled here. No, he didn't enter by mistake, but was brought in by someone, and he didn't go to Zuodu Island, but went directly to Ryugu Castle, so I don't know him!"

"That...... He claims to be a man from 500 years ago, what do you think?"

"One day on the Dragon Palace, a thousand years on earth, is practically non-existent. But ......"

Showing a strange smile, Shiranui replied at first sight,

"When you came, you were activated by a similar time-space transformation array, accidentally touched it, and arrived here. Actually, I can't say whether you are lucky or unlucky, because when you go back, you may attract turbulence in time and space, causing the way back to separate into parallel time and space, and there is no one to guide you, and you may go the wrong way."

"What do you mean?"

Such well-prepared rhetoric is still too advanced for the Konoha ninja.

"To put it simply, it is very likely that Urashima Taro was a person from 500 years ago, and after spending a few days at Ryugu Castle, on the way back, due to some changes, he crossed a long time and came to 500 years later......

"Spanning time? This...... How is that possible?"

Bai, who had been listening silently, suddenly asked, and shrugged as soon as he saw it:

"Since you know the time and space ninjutsu, then you should understand that this is a composite ninjutsu of time and space, in essence, time does not exist, it is just a derivation of space changes, since it can make you cross space, how can you cross time, it is so unacceptable?"

The four Konoha ninjas looked at each other, and after a long time, Baiyun Yeshan collected his shocked emotions.

"Excuse me, what kind of accident will lead to the way back, and there will be a change in time?"

"For example, the change of the dragon vein, the re-arrangement of fate by the gods, the influence of powerful prophecy secret arts, etc., may lead to the time when you go back, go astray and break into a timeline that does not belong to you. But ......"

I didn't know that when I saw the fire, I tilted my head and pondered for a while,

"Five hundred years is indeed too exaggerated, I'm afraid that only the power of the true god level can achieve this level. As for the treasure chest that the goddess gave to Taro Urashima, it was actually to protect him. For mortals, spanning too long a period of time is extremely stressful on the body and soul, if not

Protected by the white mist in the treasure chest, Urashima Taro will soon die and turn into a cloud of dust. Now, I'm just an old man, and I'm lucky, at least I'm still alive."

"So, the guy who broke into Ryugu City is either dead, left out of the timeline, or simply hidden?"

Shiranui smiled at the sight and didn't answer.

"That...... What are we going to do?"

Xiaoxi, who encountered this kind of thing for the first time, was already frightened, and his face couldn't help but show sadness.

"What if I go back and my parents and family are gone?"

The scene was suddenly a little difficult to clean up, and Shiranui added at first sight:

"You don't have to worry, time disturbances don't happen very often. You've caught up with the good times, and if it takes another year and a half, it is estimated that you will have to wait a long time before you can find your way home, and now, don't mess around, you should be able to return smoothly."

Next, the two parties talked a lot.

"Mayor, you don't seem to be curious about people from the outside world."

"Once raw, twice ripe!"

"A lot?"

"It's not much, but it's ......."

I don't know the fire when I see it, spread my hands,

"Four at a time, very rarely on record! The last time I saw so many people, wearing the same headguards as you, they were probably your companions."

"Huh? Then why haven't we heard of it in Konoha Village?"

"Maybe you're lonely, or maybe you're ......."

I didn't know that I had finished my words, and Bai suddenly answered,

"Are they 'lost'?"

"No, it's possible that you're on the right path and return safely!"

"This ......"

Looking at Shiranui's eyes that seemed to be smiling at first sight, Bai suddenly had a bold idea,

"I would venture to ask, the last time you saw Konoha ninjas, what were they like, and what era did they come from?"

"If I'm not mistaken, it should be the sixty-fifth year of Konoha!"
