Liu Lang carried a small army-green cloth bag, which is the standard for students, with books and pen and paper in it, and the four of them came out of the dormitory in a hurry, and hurried to the classroom hundreds of meters away.

"Slow down, wait for me!"

Liu Lang can't catch up with the three people running from behind, this can't be helped, Liu Lang is just over one meter tall now, which is not short for a three-year-old child, but compared with a seventeen or eighteen-year-old boy, it is half a body, and the small short legs are not as long as others.

"Let's go!"

The boss Juniper turned around and picked up Liu Lang and ran forward desperately.

When the four people came to the classroom, they saw an old man standing at the door, full of white hair, even his beard was white, wearing a blue khaki shirt, and the clothes were still oily and twisted, as if he hadn't washed it for a month.

"It's over, it's late!"

Juniper put Liu Lang down, and the three of them panted timidly and walked up to the teacher.

"Professor Xiong!"

The three juniper had their heads down, their hearts pounding, and they had a premonition that the "storm" was coming.

This professor is called Xiong Huaizhi, is the dean of the School of Engineering, this year is almost seventy years old, don't look at the age is not young, but the temper is very hot, the requirements for students are very high, at the same time his knowledge is also very large, a person teaches "materials science", "smelting", "material mechanics" three courses, because of the hot temper, plus the beard is white, he was secretly given a nickname of "polar bear" by the students of the last two sessions, the new students dare not call this nickname, usually replaced by the old bear.

Liu Lang listened to other classmates talk about Xiong Huaizhi's experience, he is not an ordinary person, his ancestors have been industrialists in the south for several generations, and he is a steamer, it can be said that he is the earliest batch of industrial enlighteners in modern times, and his grandfather's generation is a wealthy family, and it is said that the family has nearly 1,000 tons of ocean-going ships.

Xiong Huaizhi himself received a good education since he was a child, in the early thirties, he went to Germany to learn the most advanced shipbuilding technology, after completing the study, he wanted to continue his studies, but in time for the outbreak of World War II, Germany could not stay, and returned to China and wanted to strengthen the family, but the island people killed in, the family dedicated the ship to the country, and finally sank to the bottom of the sea in the fire, the country is finished, the Xiong family and other national capital industrialists who have just started are helpless in the face of the general trend, watching the wealth accumulated by their generations, and the hope of revitalizing the national industry disappear together。

The Xiong family fled to Nanyang, Xiong Huaizhi was sent to the United States to start learning industrial technology again, this time in the mid-forties, the foreign enemy was beaten away, Xiong Huaizhi returned from learning and wanted to do something, but the civil war began again, until the establishment of New China, and finally he had the opportunity to serve the country, and the country did give him the opportunity to serve as the chief engineer of the Jiangnan Shipyard at that time.

Xiong Huaizhi's technology is not said, the country is one of the best, but the temper is not very good, if someone can not meet his requirements when working, then it is a burst of scolding, interpersonal relations are very poor, in China, your interpersonal relationships are not good, then the problem is big.

In the late fifties, Xiong Huaizhi, as a senior member who had studied in Germany and the United States, was "duty-bound" and was labeled as a "stinky old nine", and was not allowed to work, and was locked in the room every day to write inspections, but fortunately, his ability was too great, and the people above specially protected him and did not suffer too much impact, but after another seven or eight years, the ten-year catastrophe began, and no one could help him this time.

Got off the cowshed, was criticized, Xiong Huaizhi can experience all the experience, fortunately, he has a tough body, upright personality, and finally survived to seventy-seven years, after the rehabilitation, the state still wants him to hold the original position, but he is old, and he also knows that his personality is not suitable for leading others, so he volunteered to teach at Huaxia University.

People like Xiong Huaizhi and Lu Mingzhi are all technical backgrounds, have received a good education abroad, but the two are very different because of their personalities, Lu Mingzhi has practiced medicine since childhood, and dealing with people has to be more sleek, in addition to the principle of the problem, the others can turn a blind eye, Xiong Huaizhi is different, people engaged in mechanical engineering are faced with cold machinery, every part must be extremely accurate, can not rub a little sand, the slightest mistake can lead to the scrapping of a piece of equipment, it can be said that the professionalism of two people determines their character。

Once the character is cultivated, it is a lifelong thing, Xiong Huaizhi is the same in school, he is very strict with the students, if you don't understand, ask immediately, if you don't ask, wait until you don't understand the exam, then you will suffer, but the courses he teaches are very difficult, and it is not easy to fully understand in a short time, so these students are terrified every time they take his class.

"You all know the rules, let's make these questions first!"

Xiong Huaizhi threw the dry tobacco in his hand into the ground and turned around and walked into the house, and Liu Lang and the four people followed.

The others had all arrived, and when they saw Liu Lang and several people being late, they all showed "sympathetic" expressions.

"Liu Lang, you are too young, go and sit in your seat. ”

Xiong Huaizhi pointed to a chair at the front and said.

Liu Lang is a special existence, even if it is a hot-tempered "polar bear", it must be convenient.

There are three questions on the blackboard, all of which are knowledge of mechanics, and Xiong Huaizhi pointed to let the three of them do it together.

He Tao reacted the fastest, glanced at the blackboard and jumped onto the podium without saying anything, picking up a topic that he thought was quite easy.

Lin Hai reacted slowly, showing a look of remorse, and at the same time jumped on the podium to find a question to try to do, the last question seemed to be very difficult, Juniper pinched the chalk and didn't know where to start.

Three minutes later, He Tao did the question, his face showed joy, it seems that today's scolding was avoided, Lin Hai wrote half of the question, but it seems that there are some problems, and he keeps revising, and Juniper is sweating, this question is simply beyond the scope of the current course, and it can't be done at all!

"Okay, He Tao, you go back, the remaining two have not done it, according to the regulations, the two of you will be punished for this class, and you will have to complete the special homework I left for you after you go back, Liu Lang, if you can help them do it, the two of them will be exempted from this punishment." ”

"Then I'll try!"

Liu Lang got up from his seat, and then went to the blackboard of the podium.
