The hall on the first floor was empty and uninhabited.

Kaito's observation ability is extremely strong, and he can spot the surveillance that exists on the first floor at a glance.

Dodging as hard as he could, he avoided several cameras and reached the surveillance room.

There was no light in the monitoring room, and Kuaidou raised his wrist and gently pressed the watch button, and the faint light shone out.

Not far away, there is a large screen, 48 small screens, from bottom to top are 1~6 floors, each floor has 8 internal and external monitoring.

He sat in the black rocking chair in the middle, observed the screen, quickly glanced around, and found that there were five people on the rest seat on the sixth floor, Ivan, Alex, Ben, Karl, and Eguchi Plains, everyone was dressed in a white suit, and they were talking.

Kuaidou controlled the monitoring mouse, constantly clicking and checking, and did not find Jiang Zhe and Leon in the world.

In the storage room on the 4th floor, it is discovered that the world's Kaito is assembling something using parts.

On closer inspection, it looks like assembling a weapon.

Seeing this scene, Kuaidou pinched the headset and announced: "Jiang Zhe and Leon in the world have found no traces, there are five people on the sixth floor, I turned back and didn't find the existence of the two, you guys be careful, I will continue to monitor, by the way, the people in this world are also wearing white suits, this world's version of me in the storage room on the 4th floor, I will continue to keep an eye on it, and you will solve the people on the sixth floor if you find an opportunity." ”

As the words fell, Jiang Zhe's voice came from Kuaidou's headset: "Received." ”

Just when Kaito wanted to continue browsing the surveillance, "Bang! With a low muffled sound, Kuaidou felt hit by a hard object on the back of his head, and then a strong dizziness struck, and he immediately fell to the ground after his body was unstable.

At this time, at the staircase on the 4th floor, Jiang Zhe finished receiving the information and looked at Leon, who also heard Kuaidou's announcement.

Leon pondered and asked, "Are we pretending to be both of them?" ”

Jiang Zhe said: "Well, but don't startle the snake, the main enemy is us, and the other five are not a big threat." ”

It was certain that the sixth floor was safe, and Jiang Zhe and Leon walked up to the sixth floor with peace of mind.

The venue on the sixth floor was extremely empty, and next to the snack vending machine in the rest seat, five people led by Ivan were drinking coffee and talking and laughing.

Hearing the sound of footsteps, Ivan raised his hand, "How did you come back, we know how to find out who is from another world." ”

Jiang Zhe and Leon glanced at each other, did not speak, walked over, and sat in the first seat.

Seeing the two returning, Ivan got up, walked to the front, and explained to the six people in front of him: "They are back, we should talk about how to distinguish visitors from another world." ”

Alex raised his hand and asked, "How can you tell?" ”

Eguchi Plain pondered, "If it weren't for the same world, there would be something wrong with the cognition and common sense in my mind. ”

Ben pondered and asked, "How about using historical questions to solve problems?" ”

Karl shook his head and rejected the proposal: "No, many of us here don't know anything about history, and if there are multiple parallel worlds, we all know about major historical events, and it is almost impossible for big events to go wrong, so it's better not to ask about this." ”

As the words fell, Ben and the others' eyes were projected on Jiang Zhe and Leon, as if they were asking for opinions.

Jiang Zhe said expressionlessly: "I don't care. ”

Leon chimed in: "Any question is fine, as long as you can tell who is a visitor from another world!" ”

Looking at the discussion of the six people in front of him, Ivan's gaze stayed on Jiang Zhe's body, "Jiang Zhe, what do you think is the most appropriate issue, so many of us are meeting for the first time, and it is difficult to know each other's bottom line." ”

Hearing this, Jiang Zhe disguised himself very well, after all, he and Leon were visitors from another world, and they could not be exposed.

Even if Jiang Zhe and Leon return to the world for a while, as long as he and Leon take the lead in saying: [Those two people are fake], it is not a big problem to be deceived and passed.

After thinking about it, Jiang Zhe said: "Historical events, according to the butterfly effect - the small gaps and choices in each world can lead to a number of different future directions, and I am personally inclined to Uncle Ben's proposal. ”

Hearing this, the history professor smiled, "Yes, I think so too. ”

Seeing this, Ivan nodded silently, "Well, what does the Declaration of Independence mean, and when and where was it issued?" ”

"I'll count to 10 and everyone will answer together!"

“1...”

As the question fell, Professor Ben and Alex and the others looked at each other and smiled.

This kind of question is simple for those who grew up in a beautiful country!

Only Jiang Zhe and Leon observed Professor Ben and the others casually.

Each world's declaration of independence does not necessarily coincide with the same period, and its meaning may be different.

As Jiang Zhe and Lyon know, the "Declaration of Independence" was adopted on July 4, 1776 by the beautiful mainland, and this historic declaration declared the independence of the beautiful country from the rule of the corrupt country, and gave the people the right to freedom.

“10！”

As Ivan's countdown fell.

The crowd led by Professor Ben said in unison, "October 4, 1780." ”

Seeing this scene, the audience and experts were surprised.

"!! adopted on 4 July 1776"

"Yes, it won't be October 4, 1780."

"It's nothing, the time of independence in parallel worlds is different."

"Wonderful, I didn't expect that there really would be a parallel world in which the independent time was not in 1776!"

“...”

The audience realizes the wonder of parallel worlds.

In the picture, Jiang Zhe and Leon's pupils shrank suddenly, and they reacted slower than everyone by a beat, perhaps deliberately, and if they answer, the time may be instantly exposed.

Fortunately, the two of them were quick to move, and hurriedly echoed: "Breaking away from the rule of a corrupt country, giving independence to a beautiful country, bringing equal freedom to the people, and in the next few years, the country that took the lead in recognizing a beautiful country is a developed country." ”

As the answer fell, Professor Ben looked at Jiang Zhe and Leon with a puzzled expression, "What about the specific time in the next few years - the time when the country recognized the beautiful country as an independent country, and what about the specific years, months and days?" ”

Jiang Zhe said expressionlessly: "I forgot." ”

Leon chimed in: "I don't know much about history, I only know the specific time nodes of major events, as well as part of the content. ”

Hearing this, Alex, Karl, and Eguchi Plain echoed.

"I really can't say when you asked me to say when I was recognized."

"Yes, especially since I'm a neon person, I don't know when the beautiful country will be recognized by the country."

"I'm a Hollywood movie star, and I can't say anything about that."

Ivan looked at the scene and nodded with satisfaction, "Yes, in fact, I can't say the follow-up." If you're okay, then the next question. ”

Everyone nodded, ready for the next question.

Ivan thought for a while and asked everyone: "Which book has flowed from the Xia Kingdom to foreign countries and is sought after by military, political, economic and other scholars from all over the world, and who is the author?" ”

"Countdown to 10 seconds!"

This question is well known to Jiang Zhe, a native of the Xia Kingdom.

There are two books that match, but Ivan gives a limited condition, and only one book meets the filter.

Ivan looked at everyone, "Countdown: 0, it's over, please answer!" ”

As the words fell, Jiang Zhe and others, including Ivan, said in unison: "The Art of War, Author: Sun Wu." ”

The answer to this question is exactly the same.

"Good!" Ivan glanced at everyone, "The next question, why are there no cats in the twelve zodiac signs in the history of the Xia Kingdom?" ”

"Countdown to 5 seconds!"

This question is known to anyone who has attended high school in history at home and abroad.

The timer ended quickly, "Please answer!" ”

Jiang Zhe and others spoke in unison, but the content was not the same.

Jiang Zhe said: "Cats were not common in the ancient Xia Kingdom, and it was gradually introduced to the Xia Kingdom after the Han Dynasty. In the formative period of the zodiac, that is, the Ganzhi chronology of the Xia Dynasty, cats have not yet become a common animal in the Xia Kingdom. ”

"When the Ganzhi dating method appeared, cats were not popular," Leon said. ”

Professor Ben replied, "Because cats were born in Egypt, there is a dispute over when they were introduced to the Xia Kingdom. As Jiang Zhe said, it is true that cats in ancient Xia were uncommon, but in Xia there was an animal called 'big cat', the tiger, so it replaced cats. ”

Jiangkou Plain: "There are few cats in the ancient Xia Kingdom. ”

Carr said: "Cats are not as powerful as mice, and even if they were in ancient times, they are not qualified to stand side by side with tigers." ”

Alex: "..."

Everyone's answer is much the same, they have all studied international history, especially the four ancient civilizations, and the answer cannot tell who is a visitor from another world.

Ivan frowned, "Actually, I don't know the answer to this question myself, not that I'm from another world, but that I really don't know the answer to cats." It seems that you are all very smart, and it is not interesting to ask this kind of question any longer, so why not change it to a more difficult one? ”

Professor Ben looked confident: "I don't care, I'm a history major!" ”

Carl smiled confidently: "Hollywood stars accept the challenge!" ”

Jiangkou Plain raised his hand: "Count me in." ”

Alex smiled slightly, "Accept the challenge." ”

Jiang Zhe and Leon looked at each other, and if the next question could not be answered, then they would quickly solve the five of them, but it would not prevent them from hearing what the problem was.

Seeing that everyone's interest was aroused, Ivan grinned, "Very good, it seems that everyone is very competitive, and the next problem will be very difficult!" ”

"Question: How did the world we live in come to be?"

"Countdown: 5 seconds!"

As soon as these words came out, Professor Ben, Alex, Eguchi Plains, and Carl looked at each other and nodded silently.

The countdown quickly ended, and Ivan asked, "Please answer!" ”

As the words fell, Professor Ben and the others subconsciously opened their mouths, but did not speak.

The successful lure made Jiang Zhe and Leon take the lead in answering: "The Big Bang!" ”x2

When the two of them answered, Professor Ben, Ivan and the others gave the answer with a smile on their faces: "Cloud World! ”x5

As soon as the answer came out, Ivan, Ben and the others looked at Jiang Zhe and Leon with hostile eyes, and took out a black pistol from behind and aimed it at Jiang Zhe and Leon.

Seeing this scene, the audience was stunned and terrified.
