After confirming that Ye Yin was ready, the group chat box was suddenly muted for all members, and only admins and the group owner could speak.
And after Shen Yichen said "start", Bai Pangpang immediately sent a picture to the chat interface. The picture was initially 9535, and changed to another four-digit number 8546 after 0.5s. After that, each number changed every 0.5s for a full 10s, a total of 20 four-digit numbers.
Shen Yue was also watching on the side, but she just accurately remembered every number without thinking too hard. Remembering things was a side benefit, using her brain was impossible.
With such a fast speed, ordinary people would find it hard just to remember the numbers, let alone add them all up. So it was impossible to remember all the numbers in one go. They could only calculate the sum of two numbers during the 0.5s pauses to ensure accuracy.
Unexpectedly, almost the instant the last number ended, Ye Yin and Shen Jize said the answer at the same time, "148563".
The resolute answer was said by Ye Yin.
The whimpering, weak and gentle answer was said by Shen Jize.
But even though Shen Jize was crying as he spoke, everyone could still hear his answer clearly.
The two came up with the answer almost simultaneously. Shen Yichen could only take out the recording from earlier and replay it several times before confirming that Ye Yin was 0.7s faster than Shen Jize, so Ye Yin won.
The victory in the first round allowed Ye Yin to relax a little, but at the same time he became more vigilant.
Being able to keep up with his speed meant that Shen Yue's brother was very capable.
When Shen Jize heard that he had lost, his tears flowed even more, and he looked at Shen Yue tremblingly, "I'm...I'm sorry..."
Just as Shen Yue was about to speak, Shen Yichen had already reached out and patted Shen Jize on the head, "Little Four, cheer up, next question."
Shen Jize clenched the tissue box he was holding, trying his best to restrain his tears.
He couldn't cry anymore. With best of three games, he couldn't lose another one because of crying.
Next time, he had to properly give the answer.
He wiped away the new tears welling up, sobbing as he said to Shen Yue, "Sister, can you get me a glass of water?"
Shen Yue nodded and went to find water for Shen Jize.
Shen Yue remembered that every time Shen Yichen handed her water, it was warm, so she also made warm water for Shen Jize.
Shen Yichen didn't wait for Shen Jize and had already started explaining the rules for the second round, "The second round is very simple, just be the first to solve the problem given by the judge. But I remind you, the second question is not simple addition, subtraction, multiplication or division, but a differential equation without elementary function solutions. Ye Yin, are you familiar with knowledge in this area?"
Ye Yin was not at all surprised by the terminology Shen Yichen mentioned, clearly knowing about it.
"I am."
"Then do you have the ability to mentally calculate this type of equation?"
Ye Yin was actually a little unsure. He could calculate, and was very confident he could calculate faster than ordinary people, but he couldn't be certain he was faster than Shen Yue's brother across from him.
"I...can."
Receiving an affirmative answer, Shen Yichen directly said, "Begin."
After Shen Yichen finished speaking, the chat box showed another question: ly′′+gy=0.
The instant Ye Yin saw this question, he started calculating in his head.
Shen Jize also started calculating. At this moment, Shen Yue had just brought water over to him. He glanced at the question, then grabbed Shen Yue's water and took a big gulp, then clearly said the answer.
"y(t)=Ce−i√g/l•t"
The speed was as if he had gotten the result from the moment he saw the question.
Ye Yin still had the last step left to calculate the answer, when he heard a delicate yet firm voice from across.
In an instant, he understood, he had lost.
Because this answer was precisely the correct answer he had just calculated.
"Round three, take the 13th root of a 200-digit number."
When this question came out, the watching classmates couldn't help but be shocked.
They had been called geniuses since childhood, so they were naturally familiar with stories of other geniuses.
One gifted person had obtained the 13th root of a 200-digit number in 77.7 seconds. They were also curious and tried it themselves, but it usually took nearly thirty minutes.
They were very curious how many seconds Ye Yin and Shen Yue's brother would need.
They now realized that Shen Yue's brother was definitely no ordinary person.
"Begin."
As soon as Shen Yichen finished speaking, a very long string of numbers instantly appeared on the screen.
These numbers were randomly typed by one of the chubby Bai Pangpang earlier, so he also didn't know the correct answer.
Shen Jize's eyes scanned over the hundreds of digits, and with each digit scanned, the matrix in his brain changed accordingly. When he scanned the last number, he came up with the answer, "2397207667966701".
It took 87 seconds.
At this time, Ye Yin still hadn't calculated the answer, so the winner was already decided.
Shen Yichen entered Shen Jize's answer in the group chat for classmates to verify themselves.
But everyone knew this was unnecessary.
Shen Jize heaved a big sigh of relief, his tears stopped flowing, and he hugged the tissue box Shen Yue had given him earlier, looking rather proud of himself.
"Sister, I won."
Shen Yue looked at the smile on Shen Jize's face, very surprised, "Fourth brother, you smiled."
Shen Jize's upturned mouth corners paused, originally a bit nervous, but seeing the same smile in Shen Yue's eyes, his smile grew even bigger, "You smiled too."
Listening to the cheerful voices across, Ye Yin suddenly felt very uncomfortable.
This was the first time he had truly lost, not only losing in math which he had always prided himself in, but also losing...
"Ye Yin, you're also very capable, thank you." Hearing the clear and different from usual lazy tone across the video, Ye Yin was stunned.
Looking up, it was Shen Yue smiling brilliantly at him.
Yes, in that instant, Ye Yin could only think of one word.
Dazzling.
And his originally downhearted mind also instantly forgot everything, leaving only Shen Yue's smile.
Unfortunately, after Shen Yue finished saying this, the video across was hung up.
Only then did Ye Mother, who had been watching the whole thing on the side, walk up and rub Ye Yin's head, gently saying, "You've taken a liking to a very outstanding young lady, mother really likes her, so in order to defeat her brother, you also have to become even more outstanding."
Hearing this, Ye Yin didn't care about feeling down anymore, his mind full of Shen Yue's "thank you" just now.
"Mm, I'll work hard."
But why did Shen Yue say thank you to him?
"Shen Yue, why did you say that just now?"
Shen Yichen rubbed his temples speechlessly. Wasn't this stirring up feelings that had just been suppressed with great difficulty?
While using a paper towel to wipe the tears that Shen Jize had cried out of happiness again, Shen Yue casually said, "I feel like he tried really hard for me, so I wanted to thank him."
The words Shen Yichen had originally wanted to lecture her with were blocked in his chest.
After a long pause, he walked over to Shen Yue and ruffled her hair, "Mm, well done."
