"There are 15 minutes left until the end of the exam."

Zheng Fangxing's voice suddenly interrupted Li Lechen and Cheng Xixi's conversation.

Then, the classroom became noisy, with various rustling sounds of test papers being flipped through, and even muttering complaints about not having enough time and being disturbed.

The boy whose digital watch was confiscated at the beginning sighed deeply: "It's supposed to tell me the time every fifteen minutes! Why did it only tell me the time once at the very beginning, and the second time it told me the time was only 15 minutes left before the end of the exam?!"

But no matter what, the exam was over and the papers were collected.

Li Lechen ultimately decided to only write "Solution" on the last big question, as a perfect score was too high; 130 points was already a very high score.

...

...

During his lunch break, Li Lechen, clutching the one million Sunshine Coins that Cheng Xixi had given him through a loan, planned to find a live stream to spend on virtual gifts.

Through precise calculations, he figured that this round of tipping would generate 100 red envelopes, and he would receive 30 back, which would be enough to level up.

It would be wonderful if you could get both an upgrade and a red envelope.

But who should receive this million?

If only I could watch Cheng Xixi's live stream.

Unfortunately, even after scrolling through it more than a dozen times, I still couldn't find it.

[The "Get Out, Ming" food segment is currently live! The host will be tasting unofficial detoxified food. Will it be a surprise or a shock? Come and find out!]

A banner advertisement slowly rolled across the screen, and was rolled three times in a row.

I was wondering where to tip, so I decisively clicked on the ad to enter the "Food" section.

In the live broadcast room, Guo Ming was facing a row of fruits and vegetables on the kitchen counter, with a smile on his face.

He spent 3,000 Sunshine Coins to purchase 30,000 "banner rotating ad attention" services from "Xishuashua Daren".

This promotional method is more eye-catching and effective than spamming comments in a live stream; it reaches everyone regardless of whether they are live or not. While it doesn't offer the same level of reward as ads that give you "sunshine coins," it offers the best value for money.

Of course, the content of the live stream directly affects the effectiveness of the advertisement.

Sure enough, once the advertisement was presented as an unofficial detoxification process, and even included a tasting option, most people who saw the ad were drawn in.
