Having settled Huo Jiujian's matter, Li Lechen casually retrieved the "chromatographic analyzer" stored in the mall's cloud storage and returned to Gu Xiaoman's house.
In the less than ten minutes that Li Lechen was gone, Huang Yingying was indeed helping Gu Xiaoman's grandmother select beads without stopping. However, it was indeed a laborious task. After ten minutes, she had only picked out a small pile.
Until Li Lechen came back, he suddenly became incredibly powerful.
Last time, Huang Yingying didn't see the whole thing, and Gu Xiaoman's grandmother had no idea what was going on. Of course, even though they both watched the whole thing this time, they still didn't understand what was happening.
Simply place the beads in the tray above the machine according to their different colors, and then pour the mixed-color beads into the inlet. The beads of different colors can then be sorted out from the outlet.
This tiny machine can quickly sort beads of various colors. It is fast, efficient, and, most importantly, accurate.
Because there was no need to hide them this time, the entire basket of colorful beads was sorted out in no time.
"Your machine..."
"It's not some high-end technology, just a colorimeter," Li Lechen boasted casually. "I just tinkered with it when I was in the Fun Physics Research Club. It's not very practical. The principle is to distinguish the beads based on their different refractive indices."
Refractive index! Li Lechen was amazed that he had actually used the word "refractive index." Although he didn't know if he had used it correctly, it just felt very sophisticated.
He considered himself to have developed a bit of the air of a top student.
Indeed, Huang Yingying believed this nonsensical explanation because the machine was truly amazing.
Secretly, she opened her phone and searched on Taobao for "chromatographic analyzer," but the results showed all sorts of random things.
It seems that Li Lechen really made this himself.
"Oh, right!" Li Lechen suddenly remembered and asked Huang Yingying, "Did you tell Grandma about Gu Xiaoman?"
"Hmm? Xiaoman, what's up?"
Judging from Gu Xiaoman's grandmother's surprised expression, Huang Yingying had clearly not mentioned this matter yet.
Although the matter was a bit serious, it still had to be told. So Huang Yingying could only tell Gu Xiaoman's grandmother that Gu Xiaoman had suddenly fainted with a high fever in the classroom yesterday, was taken to the hospital emergency room, was diagnosed with acute leukemia, and had been transferred to the intensive care unit today.
Finally, to comfort Grandma, she added, "The school takes Xiaoman's situation very seriously and has donated some money, so you don't need to worry too much about the medical expenses."
Regardless, Gu Xiaoman's grandmother was still anxious and put down everything, rushing to the hospital with Li Lechen and Huang Yingying.
In the rush of leaving, the "chromatographic analyzer" was left behind.
However, Li Lechen didn't care much about it, because he didn't think it was important and it wasn't very practical. He decided to leave it to Gu Xiaoman's grandmother so that it would be more convenient for her to make beads in the future.
So even though he knew the "chromatographic analyzer" was left at Gu Xiaoman's grandmother's house, Li Lechen didn't go to retrieve it. Instead, he sincerely offered to give her this little product that he had experimented with.
By the time I returned to school from the hospital, it was already afternoon class time.
Exhausted, Li Lechen took the afternoon off. In any case, he wasn't the only one from the top class who didn't go to class in the afternoon; Zhou Mi was also absent and was in the comprehensive laboratory.
There was another person, Liu Yu, who returned to the dormitory shortly after Li Lechen.
It's stickier than a dog skin plaster!
Fortunately, Li Lechen had already put the little blue tablet in his "personal shop" on his way back to school, but he hadn't had a chance to say anything to Huo Jiujian yet.
"Aren't you going to the classroom this afternoon either?" Liu Yu asked knowingly, and even peeked over to see what Li Lechen was doing at his desk.
"Yes, I'm doing math problems," Li Lechen replied seriously.
"What kind of calculation problem is it? Let me see."
"The probability of winning the Super Lotto."
As Li Lechen spoke, he gestured to Liu Yu with a blank sheet of paper on his desk, on which the winning numbers from the previous two lottery draws were listed.
"......"
Liu Yu was taken aback at first, then burst into laughter: "Many people do this kind of research, but it's actually meaningless. If you could win a big prize by doing calculations, mathematics would be incredibly popular."
Ignoring everything else, Li Lechen continued to stare at the data on his phone, then copied it onto paper and meticulously circled and drew numbers.
At the same time, he had already started using a live streaming platform.
That's right, the live streaming platform was opened right in front of Liu Yu.
Huo Jiujian had been waiting for a long time.
"You only received eight thousand yuan before, how could you buy so much medicine?"
Huo Jiujian didn't immediately apply to purchase the six pills. His insatiable curiosity was a hallmark of his; how did he manage to buy something that cost 60,000 yuan? Was it actually not that expensive?
Li Lechen had already prepared his explanation: "I bought it with a personal loan."
"I see!"
"So now I need money to pay off the loan, and you should keep your promise."
"That's natural."
Then, Li Lechen showed Huo Jiujian the lottery page on his phone.
“We need data from at least the previous ten periods, otherwise it’s difficult to perform big data calculations,” Huo Jiujian said.
This is easy.
Li Lechen immediately copied down all the winning numbers from previous draws.
Besides Huo Jiujian, Liu Yu was also watching Li Lechen copy down the winning numbers without blinking. He wanted to see what kind of nonsense this guy could come up with by skipping class this afternoon and supposedly calculating the odds of winning the lottery in his dorm room.
