"Brother Lang... can I read all these information?"

Fang Chao looked at Shen Lang's subject, and his heart was filled with passion. After encountering the Zhang Lanlan incident in a short time, he fell into a state of blockage in his thoughts. At this time, he urgently wanted to empty himself or improve his math level, thereby breaking the vacancy period during this period.

Shen Lang's arrival brought the second-order operation method of linear algebra to allow Fang Chao to enter a brand new world.

It took him three hours to see it.

"I said, "Do you want to be so serious? This roast duck is cooked for you and it's colder now..."

Shen Lang interrupted Fang Chao in anger. This kid is worthy of being born for mathematics. He is completely lost as soon as he enters this field. This is a good thing for the mathematics community, but not a good thing for men.

Shen Lang can do both mathematics and pick up girls, but Fang Chao is still young and needs to show him the way.

"Ah...oh...I'm sorry, sorry, Brother Lang, I...hey, is it already so dark?"

Fang Chao glanced at the sky and found that it was completely dim. It was still very bright before they left...

"We arrived at the hotel at around five o'clock, and it's almost nine o'clock now. Do you think it's not dark this day? If you don't wake you up, are you going to see tomorrow?"

"No, no, how could this happen?"

Shen Lang smiled and said, "I didn't blame you, why are you sorry? When I was with Professor Lin, Professor Lin often forgot to eat and sleep. You are pretty good. Sometimes, professors who are trapped in research are useless no matter how you quarrel. If you even interrupt his thoughts, he will curse you directly. This person who is in a state is like having an orgasm. It's hard for you to calm him down, it's not a eunuch..."

Fang Chao: "..."

Fang Chao found that no matter how much he said, he could not compare with Shen Lang. The other party had the charm of a mature man. More importantly, if he compared himself to a sexy person, he could not compare with him.

This is an innate slutty and is too difficult to imitate.

"Do you want to go back tonight or stay here?"

"here!"

Fang Chao answered without thinking. He originally wanted to go home at night, but now it seems that he can only stay in the hotel where Shen Lang stays. The second-order calculation method of regular algebra, which Professor Lin and Shen Lang and his party, studied together, was too attractive for Fang Chao and was fatal enough, like a toxic perfume, which was addicted to it and could not extricate himself.

Shen Lang only spent about ten days in Rongcheng. After this time, he would return to Shangjing, so during this period, he would try his best to discuss some academic issues with Shen Lang.

"Okay, then you can report to your family first. Otherwise, if you don't go home these days, your family will think something has happened to you, and maybe they will call the police."

"good."

At this moment, Fang Chao called Zheng Meiling to report the news that he would not go home. Zheng Meiling quickly agreed and told Fang Chao to pay attention to safety, to eat, not to study too hard, and asked him whether he should bring you a few pieces of change clothes. It is impossible to always wear the same clothes. It is impossible to wear the same clothes for about ten days in the summer, right?

"Okay, thank you mom. I'll send you the address to WeChat later. You can send it to you any time."

"Um."

"If mom is fine, I'll hang up first."

"Um."

"Bye-Bye."

"bye."

After hanging up the phone, Shen Lang continued, "I ordered takeout too, so I won't go out for dinner today. I will hold a math society meeting in the next three days. You can stay in the hotel alone. If you are bored, go out for a walk by yourself. If you have any questions, you can ask me anytime."

Fang Chao nodded, "Okay."

The next morning, at about nine o'clock in the morning, Zheng Meiling brought a few clothes to Fang Chao, then looked at the hotel room, and then gave a few more instructions, just to not cause trouble for others, and don't be too addicted to studying. Look at the dark circles on your eyes, pandas are not as dark as you, so let Fang Chao rest early.

Shen Lang was still sleeping, and the door of his room was closed, so Zheng Meiling did not deliberately disturb him, but chose to leave. When she left, she ordered Fang Chao to call her mother if she had anything to do.

"I know, mom, you go back first, otherwise I'm afraid you will continue to wake up Brother Shen Lang."

"Well, then I'll leave."

"Be careful on the road, mom."

"I got it, I'm leaving."

...

In the next three days, Fang Chao was completely immersed in linear algebra.

As for Shen Lang, he only stayed in the hotel for one night in these three days. Most of him did not come back normally, but he just sent a picture of a beautiful woman two or three hours before he didn't come back. Of course, in the background, it is possible anywhere, bars, cafes, etc. Wherever there are mature beauty, Shen Lang will inevitably be there.

After sending the photo, Shen Lang had no follow-up, but Fang Chao knew the follow-up plot. He did not bother Shen Lang and gave him absolute freedom.

On the fifth day, maybe he was a little weak, Shen Lang took the initiative to chat with Fang Chao, cultivated his mental power, and recovered his energy at the same time.

"Chaoer, how about it? Have you learned anything?"

"Brother Lang, I don't know what to say, but I just think you are really excellent. Why did you think of using second-order operations to solve constant algebra?"

When Shen Lang heard this, his expression finally became serious. In this regard, he had few hippies and smiles on his face. "There is no way, the domestic linear algebra textbooks are basically not very good. Even with the development of technology, many calculations can be directly calculated on computers, and even in most cases, the product of the matrix is ​​calculated. The rank of the matrix is ​​actually not very meaningful. What is important is the principle of calculation...
