Doraemon: I have a book of Kuro's magic

"Ah, well..." Bito didn't want to continue arguing, but immediately changed the topic, "It's almost time to rest. I just prepared a room for everyone in the research institute. You can come with me. Let’s rest there and have a good night before we talk.”

……

In the evening, the two girls were taking a bath in the bathroom, and Nana looked at Shizuka from time to time. Talking about Bito’s dark history.

Fat Tiger and my husband had fallen asleep early, but Fat Tiger's snoring was so loud that my husband couldn't sleep.

Xiaohu: "..." It was so noisy that I couldn't fall asleep at all. I really wanted to cry without tears.

The remaining people were all lying on the bed and asleep, but for some reason, Nobita suddenly put on his glasses and opened his eyes.

Doraemon, who noticed the movement, opened his eyes in a daze and asked, "Is that so, where are you going at night?"

"Go to the bathroom!"

Looking at Nobita leaving, Doraemon sighed for some reason: "After experiencing all kinds of things, it can be regarded as leaving a beautiful memory."

Nobita yawned when he came out of the toilet, and happened to see Cen Feng and Bito on the other road.

Nobita: "???" These two people stayed up late at night. Are they planning to go somewhere together?

Curious, Nobita chased me directly, but accidentally lost me when he turned a corner.

Nobita: "???" Strange, why did the person disappear in the blink of an eye?

"Hey, you actually have a tunnel!" Nobita looked at the tunnel and sighed, "It would be terrible if I accidentally fall in!"

As a result, he accidentally slipped and fell directly into the tunnel.

Gulu, gulu, gurgle, gurgle, gurgle…

After rolling a few times, Nobita stabilized his body, and then he slid directly to the bottom of the tunnel smoothly.

"What the hell!" Cen Feng looked at Nobita who fell out and said with a smile, "Little brother, what on earth is going on with you?"

"Stop making sarcastic comments and help me up quickly." Nobita was in so much pain that he couldn't move at all.

Bito ran to Nobita's side and helped him up, "Nobita, what's going on with you?"

"No... nothing!" Nobita reluctantly explained, "I happened to see you and Cen Feng after I came out of the toilet. I was originally curious about the two of you walking together and what to pay attention to, but when I passed by a corner, I suddenly noticed you two. It disappeared, and I happened to look at a tunnel again, and then..."

Cen Feng: "..."

Bito: "..."

6...

"Hey, Goni is here too!" Nobita felt that there was nothing wrong with him, and then he realized that Goni the Whale was also in this kind of place.

But then again, where is this place?

"This is a control room built using a cave!"

"Look carefully there!" Bito pointed to a location with many pipes and said, "This is the core of the island's system that belongs to Bito."

"This red machine connected by many pipes is [pod]"

"Almost all the technology and energy used here exists here."

"Isn't this too awesome?" Nobita asked with shocked eyes, "If something can be made like this, what is your homeland, Bitto..."

"Ask Bito this question, how could Bito know?" Cen Feng rolled his eyes, "It's like asking you what happened when you were a baby. Can you answer me accurately?"

Nobita: "..."

"Ah ha ha ha!" Bito smiled, "It's true. I was just a baby at that time, so I didn't have any impression at all."

"Well!" Nobita lowered his head and was silent for a while, then suddenly raised his head and asked, "Have you never thought about going back to the past?"

"What are you talking about?" Bito turned to look at Nobita, "How could that be!"

"I don't even know when that country existed? Where is it?" Without precise location and time, how can we go back to the past?

"That's right!" Nobita, who was prompted by Cen Feng's eyes, immediately changed the topic, "I feel that Bito and Goni are both very powerful!"

"Not at all like a coward like me. I can't do anything if I'm alone."

"Actually, sometimes I quite envy you."

"You can't blame yourself for being so arrogant!" Cen Feng comforted Nobita, "At least you are quite brave sometimes."

"Beep! Beep! Beep!" At this time, [pod] suddenly flashed red.

"It's finally fully charged!" After taking out the device from Bito's house, he looked at Gorni the whale and said, "Goni, I will continue to ask you for this tomorrow!"

Goni the Whale opened his mouth and shouted a few times, indicating that he already knew it, so just feel free to leave it to him.

"Thank you for your hard work. It's already very late now. You can go and rest."

Looking at Goni who had dived into the sea again, Bito explained to Nobita who was still confused: "This pool is connected to the sea through underwater pipes."

"Oh!" Nobita nodded and asked, "Do you want to continue working tomorrow?"

"Well!" Bito said, "Because of the Goni smuggling, many things have been delayed."

"But you haven't gone home recently, right? Your family is very worried about you!"

"Also, Nana..."

Nobita originally wanted to persuade Bito to put his work aside for the time being and spend more time with his family, but after hearing this, Bito's face instantly turned serious and he looked at Nobita.

"Nobita, let me show you something."

Then, Bito performed an operation on the [pod], and soon a picture was displayed on the screen.

Nobita: "???" What is this!

"It's the underground situation of this island." Cen Feng could tell at a glance what the picture displayed on the screen was.

"Yes!" Bito said, "What this shows is exactly the underground situation of this island that was investigated a few years ago."

"The red part is lava!"

"Then, what are those blue gaps?" Nobita discovered that in addition to lava, there were many blue gaps in the picture.

"This is water trapped by the solid surface layer of the earth's crust."

"Well, is there any relationship between the two?" Nobita asked.

"Use your not-so-smart brain and think about it," Cen Feng said, "If water accumulates and accidentally comes into contact with lava for some reason, what do you think will happen?"

Nobita shook his head, "I don't know!" This is a bit related to my knowledge blind spot, and I don't read many extracurricular books. How can I know it clearly?

"If it looks like this, the water will vaporize and expand explosively."

"So, guess what will happen to this island?"

Nobita took a sip of saliva. At this time, he looked a little timid, and he had obviously anticipated those scenes.

At the same time, he also understood why Bito had to work day and night, and he didn't even have time to go back and spend time with his family.

"So now you should understand." Bito sighed, "In order to prevent this situation from happening, I must always be vigilant."

"I have such an important thing to talk about, so I can't just play around like you!"

Nobita didn't know why, but his face was a little unhappy. He turned his head and reluctantly said hello before leaving.

"Forget it, it seems like I'm just being sentimental. I'm a little sleepy, so I'll go back to sleep."

Bito: "???" What's going on? Okay, why are you suddenly angry?

"You said he might have gone a little too far!" Cen Feng tugged at the corner of Labito's clothes to remind him.

Bito also understood that Nobita probably had good intentions and wanted him to spend more time with his family and relax with them.

However, I just...

"Wait a minute, Nobita!" Bito admitted his mistake very decisively, "I'm so sorry. I know what I just said was a bit too much. I hope you can forgive me."

"Ah!" Nobita turned his head as if he didn't care, "There is no need for you to apologize to me. Besides, you didn't say anything wrong just now."

Bito didn't know why, but he suddenly took out a pendant from his neck.

"Look, this pendant!"

"This pendant should be the only thing left on me when I was a baby."

Nobita, who had already planned to go back, walked back silently after hearing this sentence and looked at the pendant in Bito's hand.

"It would be better without it!" Bito said now looking at the pendant in his hand, "Because with it..."

Bito just operated the pendant and a picture quickly appeared on it. What was shown on the screen was Bito and his biological parents when he was a child.

Nobita: "!!!" I didn't expect that this pendant actually has a hidden secret...

"When I was little, I would always cry and wonder why I couldn't see them."

"Also, to tell you the truth, I am still very nostalgic for my motherland, and I am still investigating my interest in my motherland bit by bit."

"I can't say how strong I am right now. I just want to repay the residents who took care of me in the morning, that's all."

Nobita seemed to be touched sometimes, and just kept looking at Bito.

……

Time soon came in the morning, and Nobita told everyone about this incident.

Cen Feng, you said something about yesterday, and you said it in great detail. After Doraemon learned about this, he immediately took out a book about ancient civilizations and started looking for it.
