Hu Bin did not go to the second class, but assigned homework in his office, and the second class was engineering drawing, which Hu Bin was quite familiar with, and he didn't have to listen to the lecture at all.

After Hu Bin assigned the homework to the students, he began to read the engineering drawing, and after reading it, Hu Bin found that it was still much worse than the one used in the arsenal, and many knowledge points were not in the textbook.

Hu Bin looked through it, stopped reading, and began to look at the physics of the third class, and Hu Bin was going to give a lesson to the junior students in the next class, so he needed to prepare for the class.

Soon, the second class ended, and the study committee knocked on the door of Hu Bin's office, it was a boy, Hu Bin handed him the homework, and asked him to arrange for the afternoon when there was no class, copy it to the blackboard at the back of the classroom, and let those students do it.

After getting it done, Hu Bin went to give class to the junior year, after the class, Hu Bin assigned homework to the students, and then left, returned to his mother to finish eating, Hu Bin took Zhang Fan and Mo Shot to Kang University.

Hu Bin is familiar with Kang Da, there are many people sent by Division Commander Chen, as well as his old subordinate Ye Xianteng, they are very happy to see Hu Bin coming, they all surround Hu Bin, and Hu Bin also teaches those middle-level commanders when he is in class, mainly for battle deployment.

When Hu Bin was in class, many cadres who did not have classes also came to class, they all knew that Hu Bin was very good at fighting devils, and so far, Hu Bin has never suffered defeat in the face of devils, this is strength.

"Fighting with devils, remember, don't charge easily, the timing of the charge, the first ammunition is insufficient, there is no way to continue to hold on. The second is that the devils are no longer good, we use the charge to quickly solve the battle, and this situation is still that the troops need to go to other places to fight, and they need to solve the devils here first.

The third is that the time is short, and there may be reinforcements from the devil's side. And everyone also knows that the devil's bombers are very powerful, and we need to kill the devils and hide the troops before the bombers come! Hu Bin was talking above, and those cadres were listening and remembering below.

"And to deal with the devil's bombers, in fact, we do not have good means, ground air defense is only passive air defense, and the effect is not great. Therefore, when fighting, we must keep an eye on the devil's bombers, calculate the time when they fly and the time of bombing. It must be calculated, before the devil bombers come, the troops must hide well! Hu Bin was still talking on it.

"Also, for sneak attack devils. Also pay attention to the covert, preferably at night march. At the end of the battle at night, many people may say, you can't win, the devil's firepower is strong, and he is well-trained!

But I will say that we are not bad in firepower now. Even if the firepower is poor, we have to concentrate on using our heavy firepower, and a single point breaks through first, and then deploys! Hu Bin stood on it and talked for more than 2 hours. Hu Bin's class has just ended.

Then, Hu Bin went to listen to other people's courses with other students, and in the evening, Hu Bin had dinner with the students from Shandong, Hu Bin had come out of Commander Chen's army before, and he was familiar with those cadres, even if he was not familiar with them, he was also a member of his mother's family, and he was very kind when he saw it.

Hu Bin stayed at Kang Da until more than 8 o'clock in the evening, then returned home, and after sitting with his mother for a while, Hu Bin returned to his own house, or continued to study the affairs of the arsenal.

Now when there is a problem in the arsenal, it sends a telegram to Hu Bin, asking Hu Bin to help him find a way to solve it.

Half a month has passed, at this time, Hu Bin's fame in the Academy of Natural Sciences has also risen, those students like to listen to Hu Bin lecture on mathematics and physics, whenever Hu Bin goes to class, the whole classroom is full, and then it is really impossible to sit down, Liu Kang arranged for Hu Bin to give a lecture on the playground, and those students sat on the playground to listen to Hu Bin's lecture.

"Sister Wanru, that Wang Wenwu really has some ability!" At this time, Liu Jingya said to a girl next to her, that girl's name is Li Wanru, and she is also the daughter of an old professor in the school, according to modern terms, the two are best friends.

"Listen to the class, your father will know that you are not attentive in class, and I guess he will scold you again." The girl named Wanru smiled and said to Jingya.

"Cut, I'm afraid of him, hmph, because of Wang Wenwu's matter, I was also scolded." Liu Jingyao wrinkled her nose and glared at Hu Bin fiercely and said.

And Hu Bin didn't know at all, he was still lecturing in front, telling students about the difficulties in the content, and where to start solving the problems encountered.

Because they saw that Hu Bin sent out more homework than they thought, and the lectures were also very good, they also came to study.

After finishing the math class of the freshman year, I will soon have to take the physics class of the third year, and there are still hundreds of people listening to the class.

For the rest of the time, Hu Bin lectured like this, and when it rained, Liu Kang would let Hu Bin rest and let the students go to other classes first.

On this day, Hu Bin was sitting in his office, still thinking about making money.

"Made, if this continues, I will have to be forced to death by them!" Hu Bin touched his head and said.

During this time, more and more funds were consumed every day, and now thermal power stations are also being built, plus the cost of research, in just one month, 3 million oceans have been consumed.

Hu Bin went to the commander-in-chief and commander-in-chief, and they did come up with money, but thinking of next month, Hu Bin needs to build a large wind tunnel and forging press, and it will cost a lot of money here, and it is estimated that the consumption of next month may exceed 5 million oceans, and the purchase of weapons and distribution to Hu Bin is about 3 million oceans, so that the gap is still 2 million oceans.

"Knock knock!" At this time, there was a knock at the door.

"Come in!" Hu Bin shouted.

"Brother." Zhenguo poked his head out, looked at Hu Bin and said with a smile.

During this time, Zhenguo was really convinced by Hu Bin, especially when he heard Hu Bin's classes, he wondered if Hu Bin really didn't go to college, and if he hadn't attended, how could Hu Bin know so much.

Another thing that he admires more is that Hu Bin is very good to students in school, and he teaches seriously, not like a military commander at all, because Hu Bin is not majestic at all in front of students and teachers, and he is very approachable.

What he doesn't know is that Hu Bin attaches great importance to education, and it can be said that Hu Bin has made great contributions to the establishment of so many new schools in Yan'an, and Hu Bin paid for the establishment of some schools.

"What's the matter, aren't you in class?" Hu Bin looked at his watch, and it was not yet time to end class, so he asked.

"There is no class in this class, by the way, it's not me looking for you, it's them looking for you, and they say they have questions to ask you!" Zhenguo let go as he spoke, and at this time, Liu Jingya and Li Wanru also appeared at the door.

"Oh, come in!" Hu Bin heard it and nodded.

"Hello Mr. Wang, Mr. Wang, we have a few physics problems that we haven't understood, please help us explain!" Liu Jingya looked at Hu Bin and said with a red face, he also said that Hu Bin came in through the back door, and now Hu Bin's strength has also convinced her.

"Oh, I don't understand anything, bring it! ~" Hu Bin nodded, he didn't care about these at all.

"Teacher, look, we wrote it in the notebook, you can help us answer it." Li Wanru looked at Hu Bin and said.

"Good!" Hu Bin took the notebook, began to calculate, and then gave them answers, and when they got to the back, the two of them came almost every day. Hu Bin didn't care.

It was the weekend, and Jingya and Wanru were walking on the school path, chatting and chatting about Hu Bin somehow.

"Sister, that Wenwu is just a piece of wood, right?" Jingya looked at Wanru and said.

"What's wrong? Do you like him? Wanru looked at Jingya with a smile and asked.

"I don't like him! I mean, hee-hee! Jing Ya looked at Wanru and laughed.

"What are you laughing at, don't think I don't know, you and that Zhenguo secretly write love letters, be careful I tell my uncle!" Wanru looked at Jingya with a smile.

"You dare?" Jingya looked at Wanru in surprise, wondering how she knew that she had written a love letter to Zhenguo.

"Hee-hee, the little girl has grown up." Wanru laughed.

"Hmph, don't you do the same, you write a lot of love poems in your diary, it seems to be written to someone." Jingya looked at Wanru with a smile.

"You dare to peek at my diary, I, I, I can't spare you." At this time, Wanru blushed like an apple, and immediately chased Jingya and fought.

"Hehe, how can you peek, it's you who didn't put it yourself, I just looked through it, where did I know that there was such a big secret inside!" Jingya ran with a smile in front, and Wanru chased behind.

"And say, don't say it!" Wan was about to cry when she was so anxious, she didn't expect that her secret would be known by Jingya.

"Okay, okay, I'm not going to talk about it. But, sister, you've been secretly liking it like this? Jingya saw that she was in such a hurry, and immediately went over to comfort him.

"What can I do then, he's a teacher." Wanru looked at Jingya and said.

"What's wrong with the teacher, don't look at him as if he is very mature, he is half a year older than Zhenguo, and he seems to be a month younger than you!" Jingya looked at him and said.

"How do you know?" Wanru looked at Jingya and said.

"Hee-hee, or I'll drag you to see him every day? I asked Zhenguo's. Jingya looked at Wanru with a smile and said.

"You, did you tell Zhenguo?" Wanru's eyes widened and she looked at Jingya.

"Ah, it's over!" Jingya knew that she had slipped her mouth, and immediately stuck out her tongue, knowing that this was trouble. (To be continued.) )
