Ch3: Oh! By the way, I am your son-in-law in universe-9188

Finishing his studies in the library, Barry got up from his seat and walked towards the reading area with a pile of books in his hands. He saw a figure sitting near the right corner of the room near the window.

Being curious, he walked towards the figure and saw the same blonde girl reading the "Quantum-Space and Time Relations." At the same time, her hands were busy calculating the formulas.

"She's still here?" He looked towards her with a curious gaze.

The afterglow of the sun shone through the window, making her look like an angel.

Perceiving someone looking at her, she turned towards him and saw him standing near the table observing her.

She raised her head and asked with a polite voice, "Is the library closed?"

Barry shook his head and replied, "No, there is still an hour left."

"Oh!" The girl did not say further and continued to calculate the formulas.

This aroused Barry's interest. He walked towards her and saw the complicated formulas on her paper.

Feeling the same stare, she turned towards him and asked suspiciously, "Is there something wrong?"

Barry hesitated for a moment and said, "Are you studying these equations?"

"Yes…" She looked at him and asked, "Is there any problem with this?"

Barry awkwardly shook his head and sat in front of her. Thinking for a moment, he said, "It is hard to believe that a high school student is reading these cutting-edge papers." He wanted to slap himself for his awkward tone.

"Has someone ever told you that your approach is terrible?"

The girl said to Barry, who was sitting in front of her with a raised eyebrows.

"No, no. It's just that…" The language he brewed was stuck in his throat. He embarrassingly said, "It's that these books and equations are at least a P.hD level. For any high schooler to read these, it is a surprise."

Finding a loophole in his speech, the girl asked with a scrutinizing gaze, "So, do you know what these are?"

Nodding his head, he confirmed. Indeed he has read these papers. After all, these papers were published by Hank Pim, Tony Stark, and Peter Parker.

"Oh." She replied indifferently. Thinking that Barry wanted to impress her by bragging, she passed her papers. She said, "Then, can you help me to calculate the amount of Extra-Dimensional energies in this theory."

Thinking that she was dissatisfied with his behavior, he hesitated for a moment and nodded his head, "…Ok?"

"Here." She passed her papers.

Barry's hesitation was only for a while. After that, he took the pencil from her hands, making her flinch. He took the paper and pencil and started to calculate the formulas required to find the amount of Extra-Dimensional energy.

The girl on the opposite side was stunned. She didn't expect him to start calculating.

"Does he understand?" The girl was a little surprised. After all, the formula for finding Extra-Dimensional energy is generally taught in mid-years of physics universities.

The formulas did not take a long time. After a few calculations, he returned the paper.

There was no need to check the answers because she already knew that the answer was right when she saw him calculating.

She asked, "Are you a college student?"

Barry shook his head: "No, I am a student here." He continued, "Don't I look like one?"

"It is hard to determine. Only the approximate age of a person can be seen from outside. But the change of 15 to 20 years is likely to vary from person to person." She whispered.

She continued, "But since you are only a high school student, you can understand Quantum Mechanics?"

"Uh…" Barry didn't know how to answer. So he could only retort, "Aren't you also a high school student?"

She shook her head and said, "I am different, I am…" Her voice gradually decreased.

"Then, What are you?" Because he was introverted and did not know that he was rude, he asked bluntly.

"It's nothing big. Maybe I am just a fast-learner" She recovered and replied perfunctorily.

The room fell into an awkward silence. Both of them were introverts and did not know what to say next. The girl looked at the books in his bag and asked, "Are you studying about Negative Zone?"

"Uh… Yes." He said and took out the book from his bag. He continued, "This is one of the significant discoveries in the current era. After all, the discoverer of the Negative Zone is a world-renowned genius."

"Yes." The girl seemed a little absent-minded. She said, "Yeah! Mr.Richards is also one of the guardians of Earth. But, his records in the scientific community is far more dazzling than his superhero career."

Barry did not know what to say. But the girl did not notice Barry's expression and continued,

"It's a pity that he only focuses on his superhero works. Anyways, are you also proficient in Biology and Genetics?" She looked at the other books in his hands and mentioned it.

Barry nodded and said: "Yeah. However, I am not that good. Only a few bits here and there."

"Well, the human brain has its limits. It is impossible to learn every knowledge. No one can know everything. This is normal." But her statement was contrary to her current actions.

She said these words while calculating the complex formula in "Dr. Richard's 101 Theories.".

*Buzzz*

The girl's phone started to vibrate. She lowered her head and took it out of her bag.

"I'm in the library." She lowered her voice, even if there were only three people in the library.

"No, I am not on the basketball court. Why do you think that I would do such meaningless activities?"

"now?"

"Ok, I get it. I will come now."

"Also, when dad returns, tell him that he owes me one for not telling mom about his experiments."

After speaking, she hung up the phone and began to pack the papers and stationaries in front of her.

"Sorry, I will be leaving first. My brother is waiting at the gate of the school." She sorted out her papers and asked, "Can you help me to put these books in their place?"

"Yes." Barry nodded and started to help her.

After speaking, she grabbed her school bag and rushed out of the library.

Barry looked at her leaving figure and turned towards the pile of books. Shaking his head, he took them and walked towards the bookshelves, intending to place them.

"The puberty is brewing?"

Nido's old voice came from behind, making Barry sigh. Nido leaned on the bookshelf and winked at Barry. He gave him a smile that the only man could understand.

"If you don't have any work, then help me to place these books on the shelf." Barry ignored him and started to arrange the books.

Nido shook his head and said, "Slow down, Captain America, you are almost a hundred years old."

"Knowing you, Odin, you should be sleeping right now."

After saying that, he slowly walked away from the old librarian. He stopped and turned his head for the last time and said,

"This time, I am Mr. Fantastic" He started to walk away from him.

Nido looked at the leaving figure of Barry and shouted, "If you are Mr. Fantastic, then don't let Invisible Girl wait for a long time." But in return, he only received a grunt from Barry.

Inside the Chat Group.

[Iron Man: Hey! @Barry. Could you give me some answers?]

[Barry: What?! It is the 102nd time you have tagged me. Ok, I will answer your questions.]

[Iron Man: Did you really manipulated our world and added Qi to it?]

[Barry: Didn't the Chat Group answered you? Please don't disturb me]

[Iron Man: But I wanted to confirm it. Also, are there any consequences of your actions? I mean that the dangers of Qi are too much to the current civilization.]

[Iron Man: What if someone uses it for the heinous things?]

[Barry: STOP! I also know the dangers of Qi in our world. That is why I added a rule in the concept─ Only a person with Senior White's manual could cultivate Qi.]

[Iron Man: You know what, Nevermind.]

[Senior White: @Barry. Did you begin to cultivate Qi? Need any help? (¬‿¬)]

[Barry: No, I will start from today.]

[Senior White: Oh, Ok. (👍≖‿‿≖)👍 ]

[Iron Man: By the way, did you guys check out the new function of the Group?]

[Captain Yamamoto: Is there a new feature in this Group?]

[Iron Man: Due to one of the member's contribution, the Chat Group was upgraded. ヽ('ー`)人 ]

[Yamamoto: Was it the newcomer?]

[Senior White: Yeah. 👍]

[Senior White: By the way, where is @Kaguya? Is she not online today?]

[Iron Man: No. But don't worry, according to my experience with girls, She is just going through the "Edgy Phase" ]

[Barry: …? Explain.]

[Iron Man: According to Friday, there is a 45% chance that she is listening to some depressing music and posting to social media about "Women Rights" things.]

[Senior White: Is this normal? ಠ_ಠ (Worried.jpg) ]

[Iron Man: She would recover after a few songs. Don't worry about her. It only takes a few social media posts.]

[Barry: @Tony, you're mistaken. She is just going through an emotions-crisis because her boyfriend, Miyuki Shirogane, proposed to her.]

[Iron Man: How do you know that?]

[Barry: I am 50% sure.]

[Iron Man: "…" I am speechless by your words.]

[Barry: Then it would be an honor for me to be able to make "Great" Tony Stark speechless.]

[Iron Man: Finally! Finally, someone in the Group understands my greatness.]

[Barry: I want your advice on girls.]

[Iron Man: Ohh! Do you want my advice? It's not free. [̲̅$̲̅( ͡❛ ͜ʖ ͡❛)̲̅$̲̅] ]

[Barry: Do you want me to erase Stark Industries from the map of the world? ☢ ☠ ]

[Iron Man: You would not do that, would you?]

[Iron Man: Anyways, What advice do you want?]

[Barry: "…" About a girl.]

[Iron Man: Hmmm… Can you start with how you met her?]

[Barry: In the library.]

[Iron Man: Details, young man, tell the details.]

[Iron Man: From the beginning.]

[Barry: Tch! Fine.]

[Barry: I met her in the school library. She asked me to pass her the books on our first encounter.]

[Barry: Today, I once again met her there. She was studying some complex formulas and was busy calculating. I walked towards her and asked if she understood them. She got annoyed and told me to help her figure them out.]

[Barry: After that, we began to talk about science and superheroes. Then she asked me if I was a college student, to which I replied no.]

[Barry: But her mobile rang in between our conversation, and she left the library in a hurry. I did not even ask her name. Now, tell me what I should do when I see her next time?]

[Iron Man: I know, this is one of the most common encounters. She will talk to you about science in class and invite you to her home. In her house, you two will be discussing human reproduction. Nothing uncommon.]

[Barry: …This is your last chance to stop me from destroying Stark Industries. ]

[Iron Man: Tch! Fine.]

[Barry: By the way, your first advice is not suitable for the current me. Although I am a bit powerful, her brother is not something that I could mess with.]

[Iron Man: Now I am curious, What can make you think twice before acting? (Curious.jpg)]

[Barry: Her brother is someone who created his universe when he was just a kid. He is one of the most powerful beings in our universe, at least in the top ten.]

[Iron Man: !!! What?!]

[Barry: Not only her brother but also her parents. Her parents are too powerful, Father is a genius, and her mother is a superhero.]

[Iron Man: Superhero? I may have some guesses.]

[Barry: Fantastic Four… (−__−) ]

[Iron Man: Are you talking about Veleria Richards?]

[Barry: Yeah.]

[Iron Man: Also, what do you mean by Franklin is one of the most powerful beings in the universe..?]

[Barry: That is a surprise for you.]

[Iron Man: But, didn't you say that she did not tell you her name?]

[Barry: Yeah.]

[Iron Man: Then, how?]

[Barry: I saw in the future. She is my future wife.]

[Iron Man: !!! You can also see the future?]

[Barry: No, I know what you are thinking. I am not like Dr. Strange. I can only see them in pieces when I travel through time.]

[Iron Man: "…" I don't know what to say.]

[Barry: Oh! I remember one interesting thing.]

[Iron Man: What interesting thing?]

[Barry: In universe-9188, I am your son-in-law.]

"..."

[Iron Man: … Fuck you.]

"…" Tony's current mood was very complicated. So complicated that the glass in his hands was crushed into pieces.
