After the time difference, Su Xiaomu's contact with the country is no longer as convenient as before. Novel .

Just like now.

After lunch, Yi Ran and Chen Jiming drank tea and chatted for a while, then left the townhouse together and returned to the apartment which was also ten minutes away.

Su Xiaomu looked at the time on her phone, it happened to be three o'clock in the afternoon.

Speaking of time, it's hard to spare for Su Ho and Wan Dai.

After coming to the United States, I bought a few more watches for Su Xiaomu.

There are also specially explained matching occasions.

Unfortunately, Su Xiaomu still never wore it once.

"It's three o'clock..." Su Xiaomu sighed inexplicably.

He opened the phone, took a look at it, and threw it aside.

The screen of the mobile phone clearly displayed Beijing time: four o'clock in the morning the next day.

Su Xiaomu looked up at the ceiling.

I was thinking in my mind, if it were normal, what would I be doing at this time when there were no classes?

The answer soon came.

Running errands.

Or in the company.

Either meet different people, or meet the people you want to meet.

There is always someone to meet.

But in America…

After a while, Su Xiaomu got up, took the car keys and went out.

Maybe aimlessness will be an additional way of life in America in the future?

…………

Yangcheng.

Four o'clock in the morning.

silence.

Occasionally some sounds sounded on the street.

Wearing orange vests, they were cleaning the streets step by step.

The small restaurant on the street has already started preparing breakfast, behind the rolling door that lets in a little light.

There are still some people who don't want to end yesterday's wasted day and are still scrolling through their phones, computers, and everything else.

Some people have just finished working overtime and are on their way home.

There is a saying that goes well, in this huge city, who is not struggling to move forward among those who work hard?

On the top floor of a twenty-story residential building, light suddenly shone through.

Su Ho, who was wearing pajamas, sat up from the bed, and next to him was Wanda, who sat up almost at the same time.

"What’s wrong with you?"

"The same to you……?"

"well……"

"I don't know how a dead guy lives in Massachusetts?"

"Why are you still in a dream?"

"It's afternoon over there, I guess there's class going on?"

"There shouldn't be any classes scheduled in the afternoon. Today is the first day of classes."

"Look for a class schedule tomorrow."

"..."

"Go to sleep."

"Go to sleep."

"There are still three hours left..."

"yes……"

The lights came on and off, and the sound of breathing did not become steady.

The sound of tossing and turning continued and sounded continuously...

…………

…………

In the course the next morning, Su Xiaomu was invited to the podium again.

This time it is probabilistic system analysis.

It is a relatively MIT course.

Because it is a courseware compiled by MIT professors, it is a professional basic mathematics course.

Just like Professor Hills yesterday, after briefly introducing some terms of the course as an opening remarks, the professor directly asked the questions in class.

An example of a discrete finite sample space.

In mathematics, there is always something interesting.

Many people, especially Chinese students, are likely to trigger an event in their high school career:

Dropped a pen.

Bend down and pick it up.

Look up at the blackboard.

The blackboard is full of calculations and characters, just like ghostly symbols and can no longer be understood.

Since then, mathematics and myself have gone from meeting each other to becoming separated, and have become further and further apart.

In fact, Su Xiaomu did not show any talent or extra excellence in mathematics-related fields.

Although since junior high school, mathematics has gradually begun to divide the top students and the poor students, Su Xiaomu has always scored perfect.

Even at the undergraduate level, I can always get full marks in several categories of advanced mathematics.

However, these are not special cases.

When the professor raised the question, Lewis and others quickly set up a stage for Su Xiaomu to perform.

And made the operation please start your performance.

"Su, there's nothing we can do. Maybe you can give it a try?"

"Professional-related basic mathematics should not be difficult for you!"

"..."

Su Xiaomu looked at Lewis and others who were making noises, and was speechless.

I’m not a genius?!

How can I know everything?

I whispered in my heart: "Are all Americans so good at playing?"

Of course Su Xiaomu knew about things like lifting something up and falling it down.

However, looking at the countless looks in the classroom, Su Xiaomu could not refuse directly.

So I had to tell myself that on other people's territory, we must show the excellent style of the Chinese people!

"I'll try." Su Xiaomu said.

Everything that happens next is not much different from what happened yesterday.

Su Xiaomu quickly wrote down three simple but most important axioms on an A4 paper. From these three axioms, many other theorems can be derived.

"I probably have the answer..."

Su Xiaomu stopped the pen in his hand, turned it around, and looked at everyone.

"As we all know, these three axioms can lead to some important inferences, such as:..."

Su Xiaomu said and quickly wrote a line of determinants on the whiteboard.

"This process is very simple, I won't go into details."

"We all know that there are certain methods and steps for calculating probability..."
