Chapter One (Part 2)\Summer and Yue'er looked puzzled. Yue'er glanced at the letter and said, "Uh… Zichen, what does this mean?" Zichen looked at Yue'er and chuckled, "Hehe, Yue'er, aren't you usually smart? Did you get flustered this time? Hehe, okay, I'll explain it to you."\Zichen placed the letter in the center and carefully analyzed it for them: "You mentioned before that sister-in-law likes reading detective novels, so I figured this is just a prank by her for Brother Summer on Valentine's Day. The reason I think this is because of those four strings of numbers!"\"Numbers?\"\"Yes. The first line is x1224832. As I mentioned, we can treat the cross as multiplication. So this is a hint from sister-in-law: 1x2=2, 2x2=4, all the way to the last 4x8=32, each being the result of multiplying with the previous number." At this moment, Yue'er seemed to have an epiphany: "Oh~ then the next 1x3, huh? Isn't it 4?"\"It's addition!" Summer also started to catch on, "1+3=4, 4+3=7… like this!"\"Yes, that's right." Zichen continued, "And the next group is subtraction! 1-5=-4, let's temporarily ignore the negative sign. In the end, this group is also solved."\Although Summer now understood the meaning of the numbers, he still had some doubts: "But that doesn't prove anything!"\"Yeah~" Yue'er said.\"NO, NO. Hehe, Yue'er, Brother Summer, take the numbers from the second group onward, calculate the last two according to the operation rule of their group…"\Yue'er looked, and suddenly realized, "521! I love you?"\"Yes! In the second group, 2+3=5, in the third group, 1-3=2 (ignoring the negative), in the fourth group, 1, so it's the numeric code for 'I love you': 521. Therefore, we can conclude, it's definitely not a kidnapping, moreover, the heart shape is even surrounding these four strings of numbers."\Yue'er exclaimed from the side, "Haha! Zichen! You're amazing!"\"But… the location?" Summer asked.\"That's simple. Look at this letter, there are 6 paragraphs, the numeric code is 90000-5. Ignoring the negative, there are also six numbers. Coincidence? The answer is NO! 9 is in the first, which indicates the first paragraph, and the ninth character of the first paragraph is 'love'. After that, all are zeros, so there are no characters.And the final -5, the minus sign can be understood as counting backward, so the fifth character from the end is '果' (fruit), therefore, the location is 'Ai Guo Café' here with us! And the time has also been indicated, 11 o'clock." Everything was clear, and Xia Tian admired Zi Chen very much. "Hehe, Zi Chen! Not bad!"
"Ah! Brother, don't praise me yet! It's already 10:30!" Yue'er smiled at Xia Tian.
"Ah!! Right! Excuse me, Zi Chen!"
