The city owner goes up every day [unlimited]

Nan Chen looked at the scenery for a while, then turned around and returned to the long conference table, watching everyone continue to sort out the materials.

They came to Euler Demon Realm at noon yesterday, and sent more than a dozen detectors and tens of thousands of drones that day to start drawing a map of the entire world.

However, all detectors can only shoot at high altitudes, because if they are too close to the city, the city's automatic defense system will be triggered, and a ball of fire will burst into the air instantly.

The defense strength of each city is different. According to Xie Xilin's estimation, the highest level is about three levels, and the lowest level is basically zero level.It can't prevent them, but it is still no problem to prevent drones.

However, these cities do not prevent players from entering, and even the residents inside are quite friendly when they see them.

After carefully comparing all the photos, Xie Xilin directly set their main goals on three cities, and named them Basel City, St. Petersburg and Berlin City.

That afternoon, Tianyu City and Jun'an City launched a tentative long-range attack on them.

As a result, Nan Chen felt a little relieved, because Nanxing City was higher than the other two cities in terms of level and offensive and defensive strength.

It's a pity that the number of players in Southern Star City is too small, and they have to go out of the city to find clues. Every time they meet each other outside, it is dangerous.Although there was no reduction in personnel thanks to General Qin's dispatch and support, nearly a hundred people in the city defense army were seriously injured in one day.

That night, Nanchen and Xie Xilin went to the three cities together, and traveled almost all the life traces of Leonhard Euler. Finally, they saw that strange poem in the library of the Prussian Academy of Sciences.

God never sleeps,

Euler's world is endless,

In the beautiful snow-covered castle,

The magic mirror met his favorite teacher.

45:[-] a.m.,

Happy times are about to begin.

This is Euler's happiest day,

Are you ready?

My dear guests.

The whole poem was written so generously and gracefully on the marble wall opposite the entrance of the library.

Everyone who enters the library can see it clearly.

Nan Chen had just finished reading it, and before he could figure out what the poem meant, he heard someone next to him ask, "Are you the players this time?"

It was a middle-aged man with a beard and a burly figure, but his expression was still friendly.

Nan Chen didn't say a word, but the other party didn't seem to care. Instead, he smiled and said, "It's really fast. You guys came in at noon, and you've found this place now! The fastest before was five or six days."

"Before?" Nan Chen looked him up and down, "Are you also players?"

"Haha, who is not a player here?" The bearded man smiled and said, "Anyway, everyone will be residents here in the future. Let's get to know each other. My name is Kadalu. How about you?"

"Nan Chen."

Kadalu chuckled, "Don't waste your time here, do you want me to show you around, there are many interesting things here, after a few months, you will never remember where you came from. "

"How many months?" Nan Chen asked a little strangely: "How many months will this task take?"

"Haha!" Kadalu laughed loudly, "Brother Nan, don't waste that time, let me tell you, his grandma's mission is a lie. You see the cities outside, they are all here to do it It’s a mission! But I don’t know how many centuries have passed, and no one can find where the damn magic mirror is!?”

"You said..." Nan Chen was extremely surprised, and pointed out the door: "Those cities are all for missions!?"

Some of those cities are already very large, at least with a population of nearly a million.

Kadalu was not surprised by Nan Chen's surprise, every new player looked like this.Looking for clues with great interest, after finding the clues, looking for the magic mirror all over the world, and then... there is no more.

All people cannot leave this world, so they have to be trapped here and reproduce from generation to generation.

As time goes by, the level of the city gets lower and lower, until there is nothing left to drop.

Xie Xilin on the side heard this, and suddenly asked: "What about this city? It's also a player's city?"

"I don't know about that." Kadalu shook his head: "I've only been here for less than 50 years. These are the earliest ones that existed. Who knows if they belonged to players, and the city owner must have died long ago."

"Why can't I find it for hundreds of years?" Nan Chen still finds it inconceivable: "So many of you..."

"What's the use of having a lot of people?" Kadalu snorted coldly: "It's not said in this poem that Euler's world is endless, you understand, it is infinity, where it hides, who can find it? "

"What about the time above?" Nan Chen asked.

"You can watch it at 45:[-] tomorrow." Kadalu casually pointed to the outside: "There are unwilling players trying everywhere. All the places related to time have been rummaged, and it is still here ?” “The happiest day for Ola?” Nan Chen asked, “Which day is this?”

"This player has already decoded it a long time ago. The most likely date is January [-]th, Ola's wedding anniversary." Kadalu spread his hands, "But countless people have tried it, not only on this day, but in the future you You know, people are trying every day."

Nan Chen was stunned when he heard it. Before, he thought he was very lucky to find the clue so quickly, but before he had time to be happy, he was told that the clue had been searched by millions of players for centuries but nothing was found...

Afterwards, Nan Chen and Xie Xilin carefully inspected many places, and returned to Nanxing City before dawn.

Throughout the day, everyone was sorting out the large number of photos returned by the probe.

There are too many items related to time, and as Kadalu said last night, there are basically players who have not given up trying.

Until night fell again.

This is the second night they have come to Ola Demon Realm.In front of them, all the clues point to the poem.

"There must be other clues!" Nan Chen slapped the photo on the table, "This is just the time, what about the most important location?"

"Those players are also very good." Victor rubbed his hair with a headache, "You can see, all the places where I think there is a little possibility are all guarded."

"Today, Tianyu City and Jun'an City don't seem to be bothering us anymore." Nan Chen lay down on a chair, "They must know, if they can't find the magic mirror at all, then there is nothing to grab, anyway, we have to be there It's a lifetime."

After dark, most of the photos sent back by the probes were in darkness, and there were fewer and fewer people moving around in the city.There doesn't seem to be any nightlife here. Most of the residents go home straight after nightfall. Before nine o'clock, the lights in most cities start to go out one after another, and the entire Ora Demon Realm is getting darker and darker.

Xie Xilin has been sitting in front of a huge display light curtain, drinking water slowly with a cup in one hand, and gently pushing the joystick with the other hand.

On the light curtain in front of him is the real-time image uploaded from the highest detector.

Nan Chen also poured himself a glass of mango juice, turned behind Xie Xilin, and stared at the screen for a while.

"It's very dark," Nan Chen asked strangely, "Captain, can't you see anything clearly?"

"Yes," Xie Xilin nodded, "I can't see clearly in many places."

"Then let's watch it during the day." Nan Chen felt like he was going blind after watching it all day.

Well, Xie Xilin smiled. He casually typed a few lines of commands on the keyboard to let the detector continue to scan and compare, then turned his head to look at Nan Chen, and said in a very gentle tone: "Tell me, what do you want to ask?"

Nan Chen smiled, and sat directly on the table in front of Xie Xilin. He drank a large mouthful of fruit juice to moisten his throat, and then said in a low voice, "Captain, I actually have an idea. I always feel that that clue... ...certainly incomplete."

"What a coincidence, I think so too." Xie Xilin smiled suddenly, his eyes jumped slightly, and said: "So, this clue may not be for us."

"It's not for us?" Nan Chen was taken aback: "Who is it for?"

"I don't know, I'm also looking for it." Xie Xilin reached out and grabbed Nan Chen's hand, squeezed it in his palm, and said, "The most important clue to find the magic mirror can only be the location. Therefore, the real clue must point to the only place."

"However, in this world," Xie Xilin said lightly across Nan Chen's palm with his fingers, "there are too many items and places related to time."

"Maybe it's misleading us." Nan Chen said, "This clue is fake, it's really hidden."

"I don't know." Xie Xilin stood up suddenly, "Why don't we check it out again."

"It's dark outside, I can't see anything." Nan Chen glanced out the window.

This world is not like the earth has a moon, it is really dark at night.

"It's okay." Xie Xilin pulled Nan Chen and jumped off the balcony directly, boarding a cruise ship.

According to his experience, although Skynet is black, it never gives unsolvable tasks.There must be something wrong with this world, how could millions of players not find it for centuries.

There must be something he missed.

This feeling made Xie Xilin a little uncomfortable, so he simply went to see it again in person.

Standing at the forefront of the spaceship, Xie Xilin's eyes were slightly closed, and his mental power continued to diverge, quickly covering a range of nearly [-] meters around his body.

The two explored the three cities directly related to Euler again, searched through all possible buildings, and even roughly checked the books in the library.

At two o'clock in the middle of the night, the two arrived at the best-preserved Russian Royal Academy of Sciences.

There are not only two of them in the huge and quaint building.

The number of unwilling players in this world is not low. Nan Chen not only saw many local residents, but even the city lord Mo An'an.

Even five of the six captains of the Southern Star City Defense Army came.It seems that everyone is very interested in this Academy of Sciences.

Xie Xilin and Nan Chen once again came to the luxurious bedroom at the easternmost end of the second floor.

It is said that this is a lounge prepared for Empress Catherine II, which houses many of the empress's collections.Players have preserved everything here extremely well for hundreds of years, and many of the treasures inside have remained in their original positions.

In addition to them, there are several locals in the room, waiting for something silently.

Xie Xilin stood in front of the incomparably exquisite golden peacock clock, his eyes lingering on the calendar for a long time.

He remembered that in reality this clock didn't have a calendar, but the one in front of him had an extra calendar dial.

Nan Chen followed his gaze, frowned suspiciously, and said in a low voice, "It's already two o'clock, so it should be the seventh." Why is the calendar on the clock still on the sixth?

Yes, in this world, today is the most special day in the prophetic poem.

January 1th, Leonhard Euler's wedding anniversary.
