Chapter 23 twenty three

The campus is getting quieter and quieter. It turns out that we are not walking towards the school gate, but into the depths of the campus. "Ah?" I suddenly realized, "I want to take you home!" "Did you just find out now?" Beauty No. 6 smiled. "Sorry," I said. "But I should be the one leading the way." "This……" "Anyway, the weather is fine tonight, and it's very comfortable to walk around the campus." Beauty No. 6 smiled again, "Just think of it as getting lost in the campus." "It's getting late." I said, "I'd better take you home."

"Yeah." Beauty No. 6 said, "Then let's pretend we found our way suddenly." "I'm saved." I pointed to a white fourth-floor building in the distance, "That's the Department of Mathematics building, there is a side door nearby, you can leave the campus." "Great." "We must be good people after we go out," I said. Beauty No. 6 couldn't help laughing. "I came here to attend a class last semester." I said as I passed the mathematics department building, "The teacher actually used mathematical functions to explain numerology."

"Really?" Beauty No. 6 opened her eyes wide. "Assuming that everyone's life is a regular curve, maybe a sine wave or a cosine wave, there are infinitely many possible trajectories on the coordinate plane. But for any curve, as long as one point is grasped or fixed, then The locus of this line on the plane can be completely known." "Which point?" "That point is everyone's date of birth. So Ziwei Doushu uses that point to describe and predict everyone's life, which is very mathematical." "This kind of statement is very interesting, and it seems to be very reasonable." Beauty No. 6 said.

"But this is under the assumption that a person's life is a regular curve." I said, "In fact, a person's life should not be so regular, but there should be some regularity." "The trajectory of my line and the trajectory of your line have intersected at one point a few days ago." Beauty No. 6 smiled, "If you grasp this point, can you predict the relationship between us?" "Hmm..." I hesitated, "Maybe." "How would that be?" Beauty No. 6 looked up at the night sky. "Tonight is really rare." Beauty No. 6 said, "Although it is a full moon, you can still see the stars."

"Only a few." I was unconsciously attracted by her look, and raised my head. "There are only a few stars and they are still stars. Is it possible to be called a monkey?" "You're right, it's a star." "Is your neck all right?" "Neck?" I turned my head to ask her, and suddenly felt a sharp pain, "Ah, it hurts." Beauty No. 6 couldn't help laughing. "It seems that the Department of Mathematics is not as boring as I imagined." "Yeah." I put my left hand on my neck, "Students in the mathematics department still use exponential functions to describe unwavering love."

"Exponential function?" "It's e to the xth power." I said, "no matter how many times you differentiate it, even if you differentiate it to death, the result will always be e to the xth power, which will never change." "So it's unwavering love?" "That's right." "Under the autumn starry sky, who should meet me?" Beauty No. 6 raised her head again. "Huh?" I grabbed my neck tightly this time and stopped looking up. "It's just a sudden thought of this sentence." "Maybe we have already met."

"That's right." Beauty No. 6 said, "You haven't told me yet, if you catch the point where we meet, what will happen between us?" "It's not obvious yet," I said. "Maybe in a while, please, thank you, sorry, sorry, it's my pleasure, and other kind words will be less." "I think so." "thanks." "Why do you say thank you?" "I never thought my line could meet yours." "It's not up to me." "Exactly. Sorry." "You said thank you and sorry again, are you still stuck at the moment of rendezvous?"

I couldn't help but stop and glanced at her. "Let's go." Beauty No. 6 said. "Yeah." I nodded and stepped forward a little. "Hydrangea." "Yes." I stopped and turned around, "Beauty No. 6." "The side door is here." She pointed to the direction on the right and laughed. I turned my head to look at Beauty No. 6. She had a smile on her face and her eyes were shining like stars. What will be the trajectory of the two lines between me and her in the future?
