"Professor Jim, what's your math problem doing?"

"Professor Ellie, I've got all the questions here, where are you?"

At this time, in the office, only Jim Z and Professor Ellie, who were asked by Ole and Andrew, were there, and at this time, after Professor Ellie finished the question, she couldn't help but ask Jim Z softly.

"I'm okay here, this is my topic this time, how about you take a look?" Professor Elle said with a chuckle, and then handed over a few pieces of paper.

And Jim Z, who heard this, couldn't help but chuckle and watched it, but then shook his head slightly in concealment.

Jim Z doesn't think that Professor Elle's level of questions is not very good, after all, as one of the perennial questioners of major international physics competitions, Professor Elle's level of this question is naturally one of the best in the world, but Jim Z feels that the difficulty of this question is still not enough. Although the questions presented this time are not simple in the major physics competitions, Jim Z still feels a little worse.

Not to mention what kind of level Liu Xu is in physics, but these topics are not too challenging for Andrew, a favorable contender for the gold medal in major international physics competitions, as long as he does not make mistakes.

Although Jim Z was very hidden, Professor Elle was still aware of it, and at this time she frowned and said aloud, "Is there any flaw in my question? ”

"No, no, there's nothing wrong with the question, it's just that it's ...... difficult."

At this time, Jim Z waved his hand repeatedly, but he did not fully explain his attitude, he believed that Professor Elle understood what he meant.

At this time, after hearing this, Professor Elle naturally understood what Jim Z meant, and couldn't help but chuckle and said, "I deliberately didn't come up with too difficult questions, after all, this is in Beijing University, in terms of face, I still have to talk about the past, and that Liu's ability, I actually don't know very well, so in terms of the topic, I didn't embarrass him, just according to the difficulty of the international competition, but if he really has a hidden talent in physics, then let him compete with Andrew for a while, right?" That's something I'm sure Andrew won't lose. ”

Hearing this, Jim Z couldn't help but smile bitterly, and then he thought that Ellie was still a little different from him, he was instructed by Old Man Liu, and he also had the idea of testing Liu Xu's ability, which deliberately increased the difficulty.

And this Professor Elle did not get the old man's instructions, not to mention, although MIT was invited by Plimpton this time, it was also because he did not want to destroy the relationship with Princeton, but the Massachusetts Institute of Technology really wanted to have a big enmity with Beijing University, and in this regard, Professor Elle would not deliberately embarrass Liu Xu.

After seeing Professor Elle say this, and after figuring out the surrounding situation, Jim Z naturally didn't say anything, but nodded with a wry smile.

But then Professor Elle said, "Professor Jim, I wonder if you can show me your question?"

Hearing this, Jim Z didn't hesitate, and handed it over with a slight nod, but when Professor Elle took the question and watched it, he couldn't help but stiffen there.

Although she focuses on physics, it doesn't mean that he is not good at mathematics, but even she, after seeing these problems, couldn't help frowning, and even smiled helplessly.

"Looks like you, Professor Jim, this is deliberately embarrassing those two children," Professor Elle said with a shake of his head, and Jim, who heard this, just smiled slightly.

"Knock knock!"

"Knock knock!"

"Professor Jim, Professor Ellie, the time for the exchange is almost up, if you are not ready, you can let them talk about other projects first!"

Just then, there was a knock on the door, and someone shouted there.

After hearing this, Jim Z couldn't help but say out loud, "No, wait for us for three minutes, and we can copy the question!"

……

……

"Excited, excited! Senior Brother Liu has to come on!"

"Don't worry! This time I made a rough calculation, Senior Brother can win at least three, and didn't someone say it just now? Senior Brother Liu took advantage of this time to rest, and also went to the Art Institute of Beijing University to practice an oil painting, according to rumors, the oil painting, was appreciated by everyone present, that is, Goddess Su admitted that it was a little inferior, and the skills of oil painting were not bad for Senior Brother Liu, so it seems that in terms of oil painting, Angel may not be able to beat Senior Brother Liu, so it is not impossible to win four in this competition. ”

"I've heard about it, but it's a pity that the painting didn't get around, otherwise we might have felt more at ease. ”

"Whatever? Anyway, Senior Brother Liu is not a reckless person in my opinion, since he dares to agree to ten, then he will definitely not put himself on the cross to roast, and he must have some preparations. ”

"I agree with this, let's cheer for our senior brother this time!"

……

……

At this time, the 80,000 seats in the stadium of Beijing University were already full of people, and they couldn't help but talk about it at this time, and there were even students outside who wanted to enter with their student IDs, but unfortunately because of the problem of the seats, they were blocked, and it can even be said that not counting the students of Beijing University itself, at least half of the people from more than ten colleges and universities around them rushed out, which shows the importance that everyone attaches to this matter, as well as their support and expectations for Liu Xu.

"What a horrible scene!"

At this time, Helen listened to the surrounding discussions, and couldn't help but whisper to Carlos and the others, they didn't expect that Liu Xu's appeal in Huaguo would be so great.

Fortunately, Beijing University deliberately vacated 6,000 seats for the use of people from famous foreign universities who came to participate in the centennial celebration of Beijing University, otherwise, I believe that these people can only use their mobile phones to watch the live broadcast, and this will completely become Liu Xu's home field, but even if 6,000 people are here, but surrounded by these 70,000 people, it still seems so isolated and helpless.

Carlos and the others, who heard this at this time, also glanced around and couldn't help nodding there, but Betty didn't seem to hear Helen's words, and she was still thinking about the rumor at noon.

"It's coming!"

At this time, someone suddenly shouted, only to see ten people from Ole, slowly walking in from the passage, and the media in the stands slapped at the passage, and the astigmatism even stimulated the eyes of Ole and the others, which were a little unable to open.

In addition to the 700 local media in China, some influential countries in the world have sent people to come over, and this exchange has attracted the attention of 1.5 billion people around the world, and it can be said that no matter what the result is, the people who participated today are feared to have become famous all over the world in one fell swoop, and if they can win more impressively, then they may become a hot spot in the world in the first half of this year.

At this time, the Chinese students in the stands, although they were a little displeased with these people who came to provoke trouble, but out of politeness, they still applauded there, and Ole and the others who heard this applause couldn't help but be stunned at first, and then bent down slightly to express their gratitude like people in the stands.
