The sky is gray, the grass bows its head, the branches are bent, the sky is full of dark clouds, a mountain rain is about to come, the wind is full of buildings, Chang'an, which has been hot for more than a month, is finally about to usher in a heavy rain.

Li Zexuan is wearing a very formal dress today, wearing a snow-white robe, wearing a Confucian scarf on his head, and stepping on flowing cloud clogs, quite a peerless Confucian demeanor.

This appearance is indeed very "cool", but if it weren't for today's special day, Li Zexuan would not have dressed like this. Because the shirt is cumbersome to wear, from the inside and outside are the inner undershirt, robe, socks, and scarf, the middle layer of the half-arm, the jacket, the outer shirt, the hakama, and the leather belt.

The robes of the Tang Dynasty are similar to modern suits, and they are generally worn on more formal occasions, thanks to the fact that it is a cloudy day today, otherwise Li Zexuan will definitely be regarded as a fool by others when he goes out in this outfit.

Even so, when the students of the arithmetic hall saw their husband's "amazing" outfit, they couldn't help but be stunned, and secretly muttered if their husband was funny today, because Li Zexuan usually came to class, and he dressed very casually, and he couldn't say that he was wearing a hanger, but it could only be said that he was chic and uninhibited! suddenly changed to a different style, which made the students in the arithmetic hall very uncomfortable, and several naughty tricksters were ready to "tease" out loud.

Li Zexuan didn't give them a chance to ask questions, and directly began to lecture with a serious expression.

Everyone in the church hall inexplicably felt an invisible pressure from the pavement, and a dull and depressing atmosphere gradually spread, and everyone involuntarily moved their eyes to the blackboard, even Cheng Chumo, Wang Meng, and a few other fools who were usually the most naughty and least interested in learning did not dare to make any more trouble.

"Bang Bang Bang~~!"

Unconsciously, a class passed like this, Li Zexuan, who had never dragged out the class, did not stop to let the students rest this time, as if he did not hear the drum of the end of the class, and continued to talk about his class as if nothing happened.

"After so many lectures, you should have an intuitive understanding of fractions, so I will talk about the addition, subtraction, multiplication and division of fractions. Some students may wonder, how to add, subtract, multiply and divide fractions? Hehe, in the first chapter we learned the addition, subtraction, multiplication and division between natural numbers, from natural numbers to fractions, of course, you can, but the addition, subtraction, multiplication and division between fractions will be different, please see the blackboard ..........."

Li Zexuan was meticulously and extremely earnestly lecturing on the podium, as if he wanted to stuff all his knowledge into the students below during the time of this class.

"Huh~~? Why hasn't the class ended yet~? ”

The status of the Arithmetic Hall in the Guozijian is rising, and the students of other academies are coming here more and more frequently, and soon it was discovered that the Arithmetic Gym, which has always been very normal, is very abnormal today, and the other gyms have been out of class for a while, and they are still lecturing here, so they are all talking outside through the window.

"That's not right~! Si Ye never lectures at the end of class! What's going on today? Could it be that I'm dazzled~? ”

Yuan Shuo couldn't help but touch his chin and wondered.

"It's really ~! How does Li Siye feel about what he is wearing today.... It doesn't feel right~~! ”

"And.... And you see that even Cheng Chumo is listening attentively below, it's incredible~! ”

(The person who spoke obviously knows Cheng Chumo, the old oil son of the Arithmetic Museum, very well)

"It's weird, it's still class at this time, don't they need to go to the toilet?"

(This forced brain circuit is obviously different from other students.)

................................

"Sacrificial wine, the old man heard that Li Siye is going to resign from the position of secretary?"

The Red Building of the Guozijian Center.

In Kong Yingda's study.

Wang Aaron looked at Kong Yingda with a heavy face and asked.

He was the first Dr. Guozijian to publish a policy on it when the "Datang Daily" first came out, but due to his advanced age, Wang Aaron had already resigned from his position in Guozijian, and he had not asked about the internal affairs of Guozijian for a long time.

But his qualifications are very old, even older than Kong Yingda, and most of the teaching assistants and doctors in the Guozi Prison can be counted as his juniors, so even if Wang Aaron has resigned, he has come forward in person today, and even Kong Yingda, the Guozi Supervisor, has to pay attention to it.

"Indeed, Brother Aaron!"

Kong Yingda smiled bitterly.

"How did it get to such a situation? The old man has also heard of the previous things, Li Siye just said too much in the newspaper, but many things on it are vague, and on the whole, it is still harmless, at most, you can apply for the wine, why force him to leave? ”

Wang Aaron glared at Li Zexuan.

Like Li Gang, Wang Aaron, who has half of his body in the ground, is not a rotten Confucian, he has long been able to see some problems, and he himself is very clear about some problems within Confucianism, he thinks that as long as there are methods that are helpful for students to learn, they are all good methods, Li Zexuan's blackboard, chalk, class system, pinyin, etc., have a very important role in teacher teaching and cultural inheritance, so Wang Aaron has always appreciated Li Zexuan's descendant.

"Brother Aaron~! It's not like Kong is driving Li Siye away! A few days ago, Li Siye told the old man about his initiative to ask His Majesty for his resignation, Kong was also very surprised, and repeatedly kept him, but Li Siye had already made up his mind, and Kong was also powerless! ”

Kong Yingda made a bitter face and complained.

"How so~? Can you talk to Wang in detail about the sacrificial wine~? ”

..................................

"Okay, this chapter has been all finished, everyone should remember to review and review when they go back, and complete the after-class exercises by the way, I won't give you any more corrections for this homework, because..."

After three consecutive lectures, without any pause in between, Li Zexuan's throat was a little dry, and after he finished the chapter on fractions, he looked at the students below and said in a deep voice:

"Because, this is the last lesson I will give you in the Arithmetic Hall~!"

Last lesson!!

As soon as Li Zexuan's words fell, all the students couldn't help but widen their eyes, and they were stunned in their seats, and the teaching hall fell into a dead silence, and they couldn't hear any sound, including the sound of breathing.

"Wow~!"

After being quiet for five or six breaths, the students below finally reacted, and there was an uproar!

"Sir! Why the last class~? What do you mean~? ”
