"That's a good question...... It's hard! Leng Kite said with a frown.

"Why do you feel like there's no solution to this problem?"

"I'm sure it's not out of order, why can't I understand it?"

"I seem to be barely able to understand, but I don't seem to be able to understand it."

Fang Shisong looked at the sad faces of these students, and knew that this question really stumped them.

I think he thought about it for nearly a week when he saw this problem, but what made him a little ashamed was that the last step could not be solved.

This question Fang Shisong has also discussed with others, and the first steps have been barely solved, but the last step is not understandable.

In order to be able to solve this problem, he also personally visited Professor Huabo.

However, Professor Hua Bo only smiled faintly, "There have been three people who have solved this problem. The only difference is that they spend different amounts of time. ”

"Senior Hua, can you tell me which three people solved it?"

Hua Bo's pleated face was gentle, and there was a faint nostalgia in those vicissitudes of life.

"Two of them are my students, and the last one is not to mention." Seeing that Hua Bo no longer spoke, Fang Shisong couldn't continue to ask.

"Presumably, those two students of Hua's predecessors are very good!"

"What about being excellent, in the end it's not like that." I saw Hua Bo sitting in a rocking chair and sighing helplessly.

Fang Shisong felt that Senior Hua would definitely be unhappy if he continued to talk about it, so he could only change the topic and said: "I plan to show this problem to those students of my predecessors, I don't know if they can solve it like the two students of Senior Hua." ”

Hearing this, Hua Bo was silent for a moment.

"Then let's explain!"

"Then Senior Hua, I won't disturb your rest." Saying that, Fang Shisong turned around and left.

Fang Shisong had just taken two steps, and he didn't expect Hua Bo's old voice to come again.

"If you have one, you can bring it for me to see, I haven't had a student here for a long time." Huabo actually didn't hold out hope, how many people who were so good back then can be found now?

"Senior Hua, I will."

So Fang Shisong wrote this question on the blackboard in today's lecture.

"I'll give you twenty minutes to calculate, calculate if you can, and think about it if you can't."

As soon as his words fell, many people picked up their notebooks and pens, and immediately began to count them in their notebooks.

Leng Kite was helpless: "Although this professor is famous for being able to ask questions, but today he can't understand a single step in this question?" Although the previous questions were difficult, at least she could solve them in a few steps.

Looking at Leng Kite's intermittent calculations on paper, Wan Zexi just lowered his head and glanced at the black bar in the bag through the thin slit that the bag opened.

Then the young man helplessly hooked his lips, this little guy actually fell asleep, but it was really leisurely!

"No! That's not right! ”

"It's numb, it's so difficult that people want to curse." I saw that many people tore off the page and made it into a mess.

Fang Shisong first looked at Li Jun, who had successfully solved the problem just now, and saw that Li Jun was also frowning, looking like he was meditating.

Fang Shisong couldn't help but sigh helplessly, it seems that these students of his can't solve this problem.

But he can also understand, after all, none of them can solve it, let alone these students.

It can only be said that the two students of senior Hua are excellent and very perverted.
