Bo Zijin: We're all ugly people, so there's no need to make a fuss. Let's get to the point: should the lights be on now?
Yuan Qingli: No, this order doesn't look good. The last four digits of the order number are 6748, so we can rule that out. Everyone, can you check if there are any orders with the last four digits being 7324?
Lu Xingyun: There is 24, but no 73.
Yuan Qingli: Okay.
Yuan Qingli looked at the form in her hand. According to the previous discussion, today she needed to find 5 orders with the same last digit as the first day, send them over in order, and see which last digit was lit up.
More than half an hour later, Yuan Qingli sent an emoji in the group chat, the kind that cheers and throws flowers.
Yuan Qingli: Successfully lit the first light. The first day's lighting task is complete. Now, starting with the numbers from the second day, let's see if there are any numbers ending in 0953, as usual.
The group received nothing.
Yuan Qingli: Perfect, one answer is eliminated. Next, the last two digits of the number are 8835.
Fang Zhiyou: o(*^▽^*)┛.
Everyone: Oh my god, Xiao Fang can actually send emojis.
One hour later...
Yuan Qingli: Not lit up, continue, 4540 last four digits, Wen Yuning, do you have it?
Wen Yuning: There's a 40, but no 45. I'll take it.
Everyone returned to the hall, their attention focused on the ten lamps on the wall, two of which were already lit.
Yuan Qingli sat in a chair, holding a form in her hand: "Everyone, we're in good luck today, with a 50% success rate. We've completed the amount of the previous two days in one day."
Have you found any pattern?
"I couldn't find a pattern, but I discovered a strange phenomenon."
Everyone sat down and pricked up their ears.
"Today our goal is to find orders with the same phone number as the first day, which is obviously impossible, so we'll narrow it down to the last digit of the number."
Even with a two-digit last digit, there are 100 possibilities, but have you noticed how easily we found it?
“Yes, I just thought of that too. It can’t be because we’re just too lucky,” Lu Xingyun joked.
"That means there's one thing: the last few digits of mobile phone numbers in this city are probably fixed?"
Bo Zijin touched his beardless chin. "I've also discovered something. Two of the phone numbers here have the same first three digits."
Yuan Qingli stared at the table, while everyone else opened the app. Sure enough, the first characters were all "1X8".
"Does the telecommunications boss here like to make money? Why are there so many 8s?" Wen Yuning asked with curiosity.
"If that's the case, wouldn't it be better to make them all 188, 168, and 198? But in terms of quantity, these 10 numbers are average."
"President, what else does the number 8 mean?" Yuan Qingli's gaze lingered on Bo Zijin's face.
"There are so many meanings to it. Besides getting rich, the shape of 8 resembles the symbol for infinity, so it can also mean endless. Nowadays, people often say 886 instead of goodbye. It also has the meaning of perfection, such as the Eight Treasures, the Eight Immortals, and someone with eight bushels of talent... There are too many meanings to list." Bo Zijin rattled off a lot in one breath.
It has to be said, this thing is a walking encyclopedia.
Yuan Qingli remained silent, a thought seemingly flashing through her mind, yet it was difficult to grasp.
Cast aside all distractions and greet the world with a smile.
She said, "Everyone, today is the fourth day. We still have six days. Let's take it slow."
After leaving the hall, Bo Zijin approached Yuan Qingli, which surprised her somewhat.
Looking at the expression on his face, which was full of disgust yet forced into a smile, Yuan Qingli almost laughed.
Despite having gone through two instances together, Yuan Qingli remained wary, knowing that human nature is unpredictable.
Maintaining a friendly demeanor and occasionally making light of things was not difficult. She raised an eyebrow slightly: "What are your orders, Mr. President?"
