Bai Zixiong drove the Exploration No. 2 armored car, and Xia Xiaola sat in the co-pilot. There were four people sitting in the back, Zhou Jinyin, Baicao Cheese, Baihua Qiandu and Shuguang Zhuqiang. Everyone was nervous, and Nobita said, "Fasten your seatbelts, protect yourself and your weapons, and be ready to fight at any time, we're going to cross!" ”

The armored car slowly drove in, only to see that it was dark ahead, and nothing could be seen. When all the car bodies entered, immediately, a tunnel of light appeared in front of everyone, and the armored car passed through the tunnel of light at high speed, and due to speeding, everyone was pressed back into the seats and could not move. The crowd shouted.

"Brother Nobita, where are we going?" Kora asked

"World No. 1!"

"I know it's World One," said Ra, "will it teleport us to the Ancients?" For example, the Ming Dynasty! ”

"How is that possible! Didn't the textbooks say that time is irreversible! Nobita said, "We can't teleport to the past!" ”

Time is irreversible, saying that it is impossible to rewind time (Note: In the setting of Simon Science Fiction, time will not be reversed, but it may slow down or become faster. ）

For example, what would happen if you went back in time and killed your maternal grandfather before your mother was born? If your grandfather died, you wouldn't exist, and you wouldn't be able to go back in time and kill your grandfather. This is the famous grandfather paradox, which proves that time travel is impossible! Of course, some scholars have put forward the hypothesis of the quantum universe, and going back to the past may give rise to another parallel universe, of course, this is all conjecture, and the technology of the Ming Dynasty has long proved that time travel is impossible.

That's why Nobita talks about the irreversibility of time. Speaking of this, Simon remembered a meme he had seen before: My grandfather was brutally murdered by devils when he was nine years old.

Back to the topic, I heard Nobita say: "Even if you go back to the past, it's a lighthouse star, not the Ming Dynasty on the earth, right?" ”

The passage of the light tunnel lasted about half a minute, but this half minute seemed so long to everyone.

The tunnel of light disappeared with a bang, and was replaced by a very bright light. The armored car came to a halt suddenly, and everyone rushed forward due to inertia, with seat belts to keep them from falling.

"Da da da ......" a strange sound pervades the world. The armored car was wobbly, and when I looked up, a lot of leaves were above the armored car.

Xiaola covered her head and said, "It's the palace!" ”

The soft voice of the computer: "Air composition, oxygen, nitrogen, trace amounts of carbon dioxide, water vapor, mixed with very small amounts of sulfur. The air is perfect for earthlings, and there is no need to carry oxygen equipment, and the sealed equipment can be opened. ”

Nobita was surprised and said, "Earth air? What kind of place is this? ”

The computer mommy said, "I don't know. ”

"Then you can help me analyze, what is the sound of da-da-da?" Nobita asked again.

"Please wait a minute, the analysis shows that the sound of the thud may be the sound of gunshots."

"Gunshots?" Nobita was even more strange, "Isn't the sound of gunshots swishing?" How can it be a clattering sound? ”

Nobita said that he had already opened the lid of the car, took out the hive and opened it, releasing ten little bee drones. The footage of the non-extension reconnaissance was quickly returned.

It was a tropical river, with strange trees growing along its banks that they had never seen before, and the Exploration 2 armored vehicle they were riding in was stuck in a huge tree. If it is a tree, it is better to say that it is a tree that is tangled together. The Gates of Time and Space are in these tangled treetops, tangled in branches, and it is difficult to detect them from a distance.

Exploration No. 1 armored vehicle is head-down, inserted into the river below, and the dragonfly robots and dragonfly drones that have been teleported in advance are hidden in the treetops of several uncles around them, and the five land robots are also hidden in the surrounding grass and rocks.

Nobita smiled: "These robots and drones are really funny, they are so intelligent, hide yourself first." ”

Several team members laughed and were about to get out of the car, Nobita said, "Wait. There is a case! ”

Intelligence shows that there are more than a dozen people coming from the other side of the river below, these dozen people are so strange, wearing uniform yellow-green clothes, wearing steel helmets, holding weapons, looking at this costume, they should be soldiers!

Weapons they had never seen before, and the men moved forward with great vigilance, saying strange things as they went, completely incomprehensible.

"Mommy, help me translate what these people are saying."

"Yes, Captain." Mommy said, and after a while she found the corresponding language library. Start translating.

I saw a person led by this team of soldiers, who should be a squad leader or something, so I heard him say: "Everyone pay attention to vigilance and be careful of the people of the United States." ”

"Haha," the other person said, "Kameda-kun, you are too careful, the people of the rice country have long been frightened by our Great Japanese Imperial Army, do they dare to come?" ”

"The people of the United States? The Great Japanese Imperial Army? Nobita frowned and asked, what a familiar name, he has studied the history of the earth, is it ...... No way?

"Mommy, quickly analyze the time and place now."

"Captain," Mommy said, "can't be sure of the exact time and place now. However, through the environment and characters here, it is somewhat similar to the earth in 1945 AD, Ryukyu Island. ”

"In 1945? Earth? Ryukyu? Nobita was shocked, and several others were also surprised.

"Yes, Ryukyu, aka Okinawa. These people speak the Japanese language, and they may be Japanese slaves. ”

"Isn't that a little slave?" Zhou Jinyin said, "More than 120 years ago, the little Japanese slaves invaded our Great China, created the Nanjing Massacre, and killed more than 300,000 of my compatriots. I'm going out and killing them all! ”

Nobita said: "Calm down! No one is allowed to act without my orders! Mommy, are you sure? Doesn't it say that time is irreversible? How did we go back 120 years? ”

Mommy replied simply: "I don't know." ”

Nobita said, "Listen, no one is allowed to move!" We all know that time is irreversible, and we will never go back to the past. But in the current situation, this scientific law may be broken. If it's true that time has been turned back and we have gone back in time, then we can't touch anything here, not even a little Japanese slave!

"In that case, time will be chaotic, history will have a chain reaction, and we, including Daming, may cease to exist, do you understand?"

Lara was surprised and asked, "Will it be that serious?" ”

Nobita nodded solemnly and said, "Before everything is understood, no one can move around, first turn on quantum communication and see if you can connect to the headquarters." ”
