I didn't expect to get such a big profit this time. The batch of Jinghu's goods were all handed over by them. The big boss looked at Bai Han excitedly, and patted his shoulder with the back of his thick fleshy hand: "Brother, I really have you!" Yes, you can handle such a large batch of goods by yourself in just two strokes, it’s amazing, it’s really like his grandma, when I get back to the deep sea, I have to introduce you to my good brothers..." After finishing speaking, Chao Bai was flattering Han smiled: "Don't forget me, Old Hei, when you get rich in the future!"

Bai Han raised his eyebrows: "With this batch of goods, you still haven't developed?"

Da Lao Hei's eyes lit up: "Hahaha, thanks to you, Brother Bai."

No matter how the boss behind him contacted to deal with this batch of goods, Bai Han finally found out about the girl lying on the bed.

'Unexpectedly, Jingying still has such a entangled past. Bai Han looked at the document that Bei Zi gave him, which clearly described what happened to the two of them in the United States, but what made Bai Han more concerned about this 'third party' who was very difficult to investigate.

"Miguo, gringo..." Bai Han tapped his index finger on the table slowly, he suddenly had a bold guess in his heart, turned around and told Bei Zi: "Let the three of them come back, and you don't want to stare. "

Beizi nodded and went to execute it immediately.

If it was as he thought, those gringos were not from Jingying but from this 'third party', that is to say, this 'third party' had an unusual background and was very likely to have a gangster background.

Then there is no need to send people to monitor, Bai Han believes that someone will come to him soon.

After coming to the capital for only a few days, he found an excuse to leave after helping Da Laohei with the munitions matter. He was too lazy to participate in the following matters, but a batch of munitions. Tossing out some tricks can be regarded as giving the Qinglong Gang a face, of course, Bai Han will never tell them that he is the leader of the Qinglong Gang for the time being, and they will naturally know what they should know when they are strong enough.

Leopard wanted to follow Bai Han wholeheartedly, and he would follow him no matter what he said, "Brother Bai, just let me follow you, I know I'm not capable, but I really admire you, and I don't expect to do big things, you Just be more people with more hands, wash, cook and make quilts, I will do everything, please take me in!"

With a click, he knelt down in front of Bai Han in front of Big Old Hei and Big Tooth.

'This kid! "I am still under the name of Da Lao Hei. He would follow him life and death instead of Da Lao Hei, and in front of these two people. Didn't he intend to embarrass Da Lao Hei? If Bai Han didn't Agreed, Bao Buqi took the leopard under the knife after he left.

This can be regarded as a threat in disguise, but Bai Han still admires him for being able to go all out like this just to be his subordinate.

Although Da Lao Hei was embarrassed, he had no choice but to speak now, he cleared his throat twice and said, "Hey, Brother Bai, since Leopard wants to follow you so much, let him follow you, although this kid is not good at How about it, but it’s still somewhat useful.” It’s just that it’s useful and doesn’t mean anything, obviously this is implying that Leopard is just a bum and useless, it seems that Da Laohei is really unhappy with Leopard’s behavior.

Bai Han frowned, hesitated for a moment and said to Leopard: "Think it over, I'm not a good person, after you become my subordinate, you must act according to my standards in everything, if you can't do it, get out, when the time comes No one will take you in anymore... The most important point is that I am not very safe, so dangerous things often happen around me, from now on you will have to pin your head to your trouser waist."

Leopard looked at Bai Han firmly, and said decisively: "Brother Bai, as long as you take me in, Leopard's life is up to you!"

Bai Han took a look at him and nodded, Leopard got excited and stood up abruptly: "Thank you, Brother Bai!" Then he turned around and bowed to the ashen-faced big boss Hei: "Thank you, Brother Hei too!"

Da Laohei didn't say anything more because of his sympathy, and the matter was considered settled.

"I have something to do to go to Beijing University. You take my luggage and rent two houses around. The two houses should be close to each other in a mid-range community."

Leopard hugged Bai Han's big black bag, nodded repeatedly, Bai Han glanced at him, and continued: "The money is in my bag."

"Yes, yes, I understand. The two houses are in mid-range neighborhoods, and the money is in the bag." Leopard said this and tightened his grip on Bai Han's bag.

"En." Bai Han left after giving orders. Handing over his belongings to Leopard was just a small test for him. If he couldn't even stand this test, how could Bai Han feel at ease and let a little gangster follow him? by my side.

He has no extra kindness, and he will not completely deny a person because of the background of the other party. However, how a person develops is in his own hands. Since he is eager for this opportunity, Bai Han can give it to him, but whether he can seize it? It depends on how he behaves next time.

Capital University, China's comprehensive ranking No. [-], the top ten universities in the world, the smooth design of the gate hangs a stone carving of the school name engraved with the words "Capital University" in italics. The wide electronic iron gate is opened carelessly, welcoming people from all over the world. Students and travelers from all over the world, the rustling of the mottled tree shadows on both sides of the road, has become the melody in the memory of many people.

As soon as he stepped into the campus, the smell of books settled Bai Han's impetuous heart. To be honest, he was very envious of the students who could study here. Thinking that Linjiang, his home, was a student here, he felt proud for no reason. feel.

It's just that although he came to Linjiang's school, he didn't even know which department Linjiang was in!

Bai Han patted his head, "It's really a pig's brain. When I was in the deep sea, I majored in finance, so I must have majored in finance in Beijing." Thinking of this, Bai Han immediately turned around. He remembered that the two students who passed by him just now seemed to be talking about a lecture in the Department of Finance. As long as he followed them, he might not be able to find a seat? !

After a little bit of chasing, the two students walked into a teaching building with a strong sense of design and decorated with semi-glass curtain walls. A stone slab was embedded in the wall on the ground floor, and it said - Science and Technology Building!

Bai Han raised his eyebrows, this good school is not ordinary, there is no "science and technology building", unlike their school, in addition to the "first teaching building" is the "second teaching building".

It was just that as soon as he walked into the science and technology building, Bai Han was confused. Why did the two students disappear? There are so many classrooms in the science and technology building, how could he know which floor and which classroom it was.

Bai Han scratched his head, so he could only bite the bullet and walk forward to see if there is a big classroom, "After all, it is a financial lecture, so it should be in a big classroom..." Thinking this way, Bai Han saw A large classroom that can accommodate a hundred people is full of students, and even the aisles are full of students without seats.

Bai Han was standing at the back, and before he could figure out if this was a lecture of the Department of Finance, he met the eyes of the old professor inside. The old professor's hair was all white, but his face was really not charitable. Two profound decrees Wen made him look more serious and old-fashioned.

As soon as he saw that there were still students who were "cowardly" at the door and didn't come in, he became angry, "That student standing at the back door, why are you still standing there, why don't you come in, you are already late, why are you still planning to come in?" Can't you miss class?"

Huh? !Bai Han was taken aback, looked left and right, there was no one around, so the old professor was talking about himself, but he was not a student of Peking University, before he could explain, all the students in the big classroom brushed The brush stared at him, the 'heat' was stronger than laser light.

Seeing that Bai Han was still standing there in a daze, the old professor said in a more emphatic tone: "Come in quickly, there are no seats at the back, so you can sit by the podium and listen to the class!"

Ever since, Bai Han walked from the back door of the big classroom to the podium under the "eager" eyes of hundreds of people, and the students who were sitting in the aisle stood up one after another to let him pass, and Bai Han couldn't help blushing no matter how thick-skinned he was.

It wasn't until he sat on the steps in front of the podium that the old professor started his lecture again... But Bai Han soon discovered that this is not a lecture on finance, it is clearly a lecture on technology!

It can only be blamed on him having a bit of luck today. Professor Yan Yan is the dean of the College of Science and Technology of Capital University. His class is only held once a semester. The students crowded their heads to listen. The old professor usually focused on research, and the principal gave him special permission to not bring students, as long as he had a name in the school and gave lectures to the students if he had nothing to do.

Therefore, the students who wanted to listen to his class arrived early, and this was the first time that Bai Han was an exception.

Don't look at Professor Yan's hair is gray, but his five senses and spiritual head are more than young, and he has no presbyopia. Moreover, he is as the name suggests, serious and rigid in doing things, and he can't tolerate things, let alone the slackness of students in treating knowledge With regard to attitude, Bai Han really hit the gun.

"Everyone knows that the core of a machine is its bearing, which determines the relative movement position of the rotating shaft and other parts, and acts as a supporting or guiding component. Its main function is to support the mechanical rotating body to reduce the equipment during the transmission process. Friction coefficient of mechanical load...the most difficult thing to control the bearing in precision machinery is its precision problem..."

Rustle, rustle... The sound of students taking notes came from time to time, and Bai Han unknowingly fell into the old professor's wonderful lecture. A system for understanding technology. Although they have made water purifiers before and have had academic discussions with Bruce and the others, they are all mixed with commercial interests after all, but it is different here. Knowledge about technology is constantly emerging in Baihan's mind. Then, combined with what the old professor said, we made pairwise comparisons from time to time to find out where modern technology lags behind and how to make progress.

Professor Yan obviously didn't intend to let Bai Han go easily, and when he talked about the precision of the bearing, he called Bai Han up, and Bai Han stood up with a dazed expression on his face, "It's over, this little old man probably doesn't like me, this lecture But some boiled. '

"Student, although domestic bearings have made some achievements, they are still far behind foreign countries in terms of accuracy. After listening to me, do you have any good ways to improve the accuracy of domestic bearings at a lower cost? ?”

I just listened to your last half class!Bai Han roared inwardly.

The students in the entire classroom looked at Bai Han with a look of fun on their faces. Professor Yan asked too much of a question. If he could answer this question, wouldn't it mean that he could solve the problem of Huaxia Bearing Precision? This is the problem of Huaxia bearing experts and professors. If a student can answer this question, what do these experts need?

Conversely, if a student can answer this question, his research on technology or bearings will completely surpass the current Chinese researchers.

Therefore, Professor Yan asked this question for nothing. Everyone knew that the professor was just trying to teach this late classmate a lesson, and they didn't expect him to be able to answer it.

But Bai Han doesn't know, if he wasn't in the class, maybe he would have seen these twists and turns at a glance, but he has been immersed in Professor Yan's class now, and he combined his own understanding to formulate the plan in his mind. After going through it, I scratched my head and said, "Professor, this is a bit complicated to explain, can I borrow your blackboard?"

Professor Yan, who just wanted to tell Bai Han to sit down, took a look at him unexpectedly. Although he didn't like the little guy who was late, he was always willing to give opportunities to his students as a teacher, even if the answer was wrong, he was willing to show the other party a performance. Opportunity, so Professor Yan nodded.

In fact, at this moment, Bai Han has already forgotten about the Peking University students in the large classroom behind him. His mind is full of knowledge that is about to overflow, and he must find a place to express it as soon as possible, so he has no time to estimate the surrounding environment.

There was not a single trace of chalk on the huge blackboard, so Bai Han picked up half a piece of chalk and began to draw out the ideas in his mind——If you want to improve the precision of Huaxia bearings and keep the low cost, you can start with its processing machinery and cutting methods .

Bai Han drew very carefully. Even though he used rough chalk, the precise structure of the equipment on the blackboard was clearly visible. At the beginning, some students laughed when they saw him drawing on the stage, but the expressions of the students became more and more serious afterward. The more surprised - God, what did they see!

At this time, the plainly dressed boy holding chalk on the podium is the representative of two words in everyone's mind - genius.

Even Professor Yan turned serious, and couldn't control the surprise at the young man on the stage between his brows. At first, he stepped off the stage to make room for Bai Han, but as the mechanical diagram took shape, he walked straight away. He went up to the podium and followed Bai Han, asking questions from time to time.

"Ruby was originally used here, what material did you change it into?"

"The cost of ruby ​​is too high. To reduce the cost, you can use this material instead, and use the method of reorganizing the carbon structure to achieve the hardness of the gem. I call this material C diamond..."

"So that's the case, then why there is one less detector here..."

"because……"

The original three-hour lecture eventually turned into a drawing class, not to mention, it was still a discussion class between Professor Yan and a teenager he had never met.

The Peking University students in their seats were all discussing——

"This classmate, is the boy on this stage your mechanical engineer?"

Shaking his head, "No, I thought you did the surveying and mapping, and this picture is too good!"

"I have asked many classmates, but none of them are professional."

"My classmate is the president of the Student Union of the School of Science and Technology. He said he has never seen this classmate before..."

"Isn't he a student of Peking University?"

"Do you want to post a question on the school's forum?"

"Yes, yes, post a question on the forum..."

Soon there was a pinned post on the Peking University forum: Please tell me, ask for clarification—a big guy came to the School of Science and Technology.

Below are a few photoshopped pictures of Bai Han's back, of course there is a "cute" figure of Professor Strictly in the picture.

Soon, students from all walks of life at Peking University responded one after another——

A: Do you dare to post a front view?

B: Yes, it is impossible to tell without the front view.

Lou: Forgive me, everyone, this position can only take photos of Daniel’s back.

C: Although it is from the back, it should be no problem to recognize him. The problem is, I have never met this classmate in our major.

D: Never seen +1

E: Never seen +2

……

X: I haven't seen +10086, maybe he's not from our school...

……

Lou: Thank you everyone. Our lecture is over. Professor Yan shook hands with him excitedly, and kept asking him about his major and class. Unfortunately, everyone guessed it. This student is really not from Peking University!

There was a sigh of relief.

It's just that Loulou who was present at the scene didn't say that when Professor Yan learned that this classmate was not from Peking University, he asked him for a phone number.

Of course, these are all things to say later. Speaking of Bai Han finally finished drawing the mechanical diagrams, he saw that the mechanical diagrams were all over the big blackboard, he smiled with satisfaction, and then realized that he was so majestic in front of a group of students It turned out that his face turned red again uncontrollably.

Professor Yan's small eyes were wide open at this time, and after clarifying the reason, he looked at Bai Han with a fiery look, "This student is a pillar, Huaxia's bearings are very likely to be changed because of him!" Thinking of this, Professor Yan immediately inquired about Bai Han's situation. After learning that he was not a student of Peking University, his eyes were full of pity, and then he asked for his mobile phone number without giving up, and patted Bai Han on the shoulder: "I'll call you Xiaobai, Xiaobai, you are very smart, and your research on bearings is also in place. Don't worry, I will contact you again."

Bai Han nodded foolishly, "Contact me again, will it give me a chance to study in Beijing University?" ’ Thinking of this, Bai Han nodded excitedly, put his hands on the seam of his trousers and bowed: "Thank you, Professor!"

Professor Yan's decree lines trembled, and he rarely showed a smile.

At the same time, Su Linjiang, who was about to go to the cafeteria for dinner, accidentally saw a student at the same table flipping through a campus post, staring slightly at that figure from behind... Bai Han! '

He came to the capital?

The author has something to say: Here I am again, what should I do if I am not hungry but very hungry?

Is it okay to have a good meal? !

Oh, I want fried rice with tenderloin and eggs!
