Law Enforcer's Handbook

Chapter 22 The Door to Mathematics
Lu Xiang almost never shows her emotions to others, it is difficult for you to read her mood through her expression.

I don’t laugh when I’m happy, and I don’t jump when I’m angry. When I’m depressed, I just curl up on a chair with my knees in my arms, frowning and staring at the hospital floor in a daze.

Song Lan sat beside her. He knew that the truth just now seemed to have dealt a critical blow to Lu Xiang, "Actually, as far as I am concerned, you were quite cute like that just now."

This is not a lie.

Song Lan has always believed that the power of human brain is very powerful.

It is true that Lu Xiang's almost stiff sneer makes people easily think of a murderer, but as long as he supplements Lu Xiang's background setting through brain supplementation, he can immediately appreciate the beauty of contrast and cuteness.

For example, a cold-faced female boss who is not good at words secretly practices smiling for you.

To be honest, for Song Lan who has been single for more than 20 years, this idea is still very attractive.

"truth?"

Lu Xiang turned his face sideways and stared straight at Song Lan.

"To be honest, in fact, everyone has something they are not good at, and sometimes there is no need to push yourself too hard."

Song Lan tried to counsel Lu Xiang psychologically, "Just like me, I've never been very good at calculus."

"You're not good at calculus?"

However, he never expected that his psychological counseling would bring him a surprised look.

No, isn't it normal to be bad at calculus?
Could it be that everyone in 2166 is a master of calculus?
"I failed the exam before."

"I can teach you."

"It's just an analogy, I mean..."

"Now you can."

In fact, just the word "calculus" already made Song Lan want to refuse, but when he raised his eyes, he met Lu Xiang's eyes, which seemed to be shining brightly, sweeping away the previous haze.

It is not difficult to see that she really wants to tutor herself in calculus.

Song Lan gritted her teeth, and forcefully held back the words of rejection.

A real man was born between heaven and earth, how can he be frightened by mere calculus!

However, Song Lan, as a person who never listened to the advanced mathematics class seriously, never expected that he would start a new round of calculus study in 2166.

After a while, he realized that Lu Xiang's mathematics skills were not fake, and she had really made achievements in the field of advanced mathematics.

What made Song Lan even more unexpected was that during the period of tutoring him, Lu Xiang even softened her expression. When she talked about excitement, she smiled, which was different from the previous stiff feeling. Inwardly, at this moment, it is like a little girl eager to share her treasured toys with other friends.

The speed of time seemed to speed up, and in a blink of an eye, an hour passed in a blink of an eye.

After studying for an hour, Song Lan understood one thing.

Lu Xiang looks so pretty when he smiles.

As for calculus...

What is Green's formula for?

"I didn't expect you to be so good at math."

In order to prevent Lu Xiang from giving him a surprise test, Song Lan had to change the topic first, and through Lu Xiang's tutoring, he discovered one thing - Lu Xiang is not just good at mathematics, she seems to be really I really like this world built by numbers and rationality.

Her undisguised fondness made him a little bit ashamed of a person who could pass a pass and count as a success.

"Because the person who taught me this once said that this discipline is the crystallization of human reason, and it is the key that opens a door."

Lu Xiang didn't seem to realize that the two red clouds on her cheeks were clearly visible. She said, "The person who holds this key will one day open the door to the third road."

Wait a moment……

third way?

The sudden amount of information caught Song Lan by surprise.

He vaguely remembered that on the night when the Chai Ke case happened, Lu Xiang had taught him three methods of assessing rescuers. One was the prosthetic body implantation path belonging to the krypton gold contestant, and the other was the physical tempering method belonging to the liver emperor. However, Lu Xiang skipped the third road on the grounds that "it's none of your business".

However, the way she mentioned the third way that day was completely different from that at this moment.

That night, Lu Xiang's tone was cold, which seemed to bring back an unpleasant memory for her. Now, although Lu Xiang's smile is very shallow, Song Lan can feel that she is very happy.

In other words, the prerequisite for embarking on the third path is to master advanced mathematics?
After summarizing, the three ways of becoming stronger in 2166 have been vaguely revealed in front of his eyes-this seems to be an era that belongs to krypton gold bosses, liver emperors and Xueba.

That's over.

He had no money, was lazy, and didn't even have a superficial grasp of advanced mathematics.

It seems that in the fierce competition of 2166, he is destined to be a salted fish.

However, salted fish also has dreams.

Song Lan has not forgotten his purpose of coming here today, he still has an important mission on his shoulders, and now is the time for him to blow the horn of attack.

After tutoring him on calculus, Lu Xiang's bad mood was gone. Taking advantage of the good atmosphere, Song Lan took out her mobile phone and switched the web page to the movie she had found earlier.

This is a classic movie about the protagonist's way of feigning death, stealing the world and changing the day, avoiding the siege of the enemy's net, and finally completing the counterattack in a way that the enemy did not expect.

Essentially, it's still a cool movie.

"Someone recommended me this movie before. It's good. It's good to watch a movie when you're tired from studying."

"I……"

"Proper relaxation is also very important."

Before Lu Xiang refused, Song Lan chose the option to play online.

Lu Xiang originally wanted to refuse. She has never been interested in popular movies, but when she thought of Song Lan's rare visit, she didn't refuse and watched the movie quietly.

The film is 2 hours and 13 minutes long, and the evaluation is based on facts. The overall structure of the plot is still carved out of the same mold as other movies of the same type. Even the design that the fans boasted about using the protagonist's fake death to deceive the world has long been published in other movies. It was used badly in the movie.

However, what Song Lan needs now is a fast-paced popcorn movie.

"I really didn't expect that the protagonist would think of cheating the villain by feigning death. At that time, I really thought he was going to die."

With the appearance of the ending song, he sighed against his conscience.

Lu Xiang, you must understand my painstaking efforts!

But this time, Lu Xiang seemed to have really heard his inner prayer, and she glanced thoughtfully at the ward.

"You go back first."

She said, "I still have work to arrange."

"Then you are busy first, I will come to visit the class tomorrow... What do you want to eat tomorrow?"

"egg tart."

"okay."
