Perhaps Cheng Zhu's prolonged silence in the face of the options triggered Ya's urge to communicate: "Why did Christine decide to read such a professional book? 'Analysis of the Manufacturing Principles of Magnetic Levitation Vehicles' involves many profound knowledge points, which Christine hasn't studied yet, so she won't understand it now."
Realizing there was an AI that wasn't offline next to him, Cheng Zhu immediately perked up and pointed to the string of numbers, asking in a low voice, "Is this 9998 a one-time read, or is it a permanent reading privilege?"
The main reason she remained silent was that it was too expensive.
If it costs 9998 universal points every time you read it, then this book is too expensive; but if it's a permanent reading qualification, then it's practically the same as if she bought the book. For 10,000 universal points, she could buy a reliable textbook on building aircraft, so it's not a bad deal.

After they exchanged the password, Chengzhu sent her his location.
Even faster, with the help of a librarian in a green uniform, Mary quickly found Chengzhu's spot and excitedly rushed to give her a hug.
Cheng Zhu's eyes narrowed, and he suddenly dodged, causing Mary to miss her target.
Mary looked at Cheng Zhu's indifferent demeanor with some confusion, wondering what had happened to cause such a drastic change in his personality. Meanwhile, Cheng Zhu's palms were sweating, and he kept wondering whether Mary could be trusted.
The reason is simple: the librarian who brought Mary there had a black and white identification document.
