At the foot of Jungnam Mountain, there is a wine house made of thatched huts.

Shangguan Yiren took Xiao Tao and came down from Zhongnan Mountain, and found that except for the owner of the winehouse, there were no vendors at the foot of the mountain.

Suddenly, Xiao Tao was angry.

"This group of despicable and shameless people, shameless liars, escaped so quickly!"

While chattering and scolding, Xiao Tao also clenched her small fists and waved them wildly, and her teeth grinded even more.

Looking at the indignant and dissatisfied posture, he was obviously angry.

However, for all this, Shangguan Yiren's heart seems to have expected it for a long time.

"Little Peach, do you want to continue chasing?" Shangguan Yiren looked at Xiao Tao with a smile, and there was a charm of provocation and encouragement in his expression.

"Of course I'm going to chase it, Sister Yiren!" Xiao Tao replied very seriously and nodded without hesitation.

The corners of his mouth were even higher, and Xiao Tao snorted fiercely: "Even if they run to the ends of the earth, I will chase back the silver taels, which is a whole amount of money!" ”

"This group of stinky liars dares to deceive my aunt and grandmother, be careful when you walk and fall into the pit, and raise your head to be struck by lightning!"

"Hehe......" Shangguan Yiren grinned on the spot, was amused by Xiao Tao's scolding, nodded, and then slowly walked forward, "Okay, let's go to Chang'an City first, and see the situation." ”

"Hmm!" Xiao Tao nodded without hesitation, and the anger on her face was still there.

One big, one small and two daughters, heading in the direction of Chang'an City.

……

Chang'an City, Datang Academy.

(1) Class school.

Li Chengqian and the others sat in the school hall and listened carefully to the two lectures.

In every class, there is a teacher they have never seen before.

And they're all female teachers!

At first, they were very dissatisfied.

"Miss us...... They are all princes and princes of the Tang Dynasty, and they came to study in the academy, and Li Bo'an didn't teach it himself, so he actually let a group of unknown women come to teach us?"

"Isn't that a joke?"

"What can they do with these women?"

"Why teach us?"

Li Chengqian and others scolded in their hearts.

Although they were angry, Li Shimin once told them that when they arrived at the academy, they had to listen to Li Yi's words and not mess around, otherwise they would be severely punished.

Therefore, Li Chengqian and the others calmed down for the time being and began to listen carefully to the pothos lecture.

But later, after listening to two classes, they realized that the knowledge that these unknown female teachers taught them was knowledge they had never heard of.

One course is called, Natural Sciences.

One course is called, Biology.

They immediately felt that these two courses sounded completely confused.

There is even an illusion that you can't keep up with the pace of the course.

"What kind of class is this special!"

Li Chengqian and others were a little crazy.

But fortunately, the green pothos and the maidservant Xiaoya of the Guogong Mansion, seeing that Li Chengqian and others were full of bitterness, they patiently re-explained, and Li Chengqian and others finally understood these knowledge points.

After all, they only came to study at the academy today.

Compared with the students who had already attended the class yesterday, their start was naturally a whole day apart.

It's also normal to not understand.

After the two courses were completed, Luluo and Xiaoya left the school separately.

In his spare time, Li Chengqian, Li Tai and others looked at each other.

After a long time, Li Chengqian let out a long sigh and sighed: "I really didn't expect that this guy Li Bo'an does have two brushes, and the thunder, wind, and rain we see on weekdays are actually caused by changes in the weather, not by the anger of the immortals." ”

"Yes, Brother Prince, I didn't believe it before, but ...... According to the explanation of the course, this explanation is indeed very reasonable. ”

"Exactly, with this course, we won't have the idea of 'gods moving anger' in the future."

"No wonder my father wants us all to come to the academy and study hard."

"Let's listen well in the next class."

"Of course, Brother Prince......"

A group of princes smiled and nodded.

At this moment, in their hearts, there is no longer any doubt.

After all, the compiler of these textbooks is none other than Li Bo'an.

They believed that if Li Yi's textbook was wrong, their father would definitely trouble Li Yi, so there could be no problem with this textbook at all.

"Jingle Bell ......"

A series of crisp preparatory bells rang, and Li Chengqian and the others hurriedly sat down, waiting with anticipation for Li Bo'an to give them a math lesson.

But at the same time, Wei Zheng and Fang Xuanling came to the (first) class school together.

"The student has seen Master Wei, Master Fang." Li Chengqian waited for the prince, and hurriedly got up and gave his hand.

After all, they are still one child now.

Although their identities are indeed very noble, and Fang Xuanling and Wei Zheng are their courtiers, Wei Zheng's poisonous mouth is well-known in the Tang Dynasty.

And Fang Xuanling's plan is even more famous.

Seeing that the two of them also came to the school, Li Chengqian and the others thought that Li Shimin had sent them to supervise them, so they were still a little afraid in their hearts.

What's more, Wei Zheng and others are the crown prince and are deeply loved by Li Shimin.

A little kid, can he not be afraid of the teacher?

"The old minister has seen His Royal Highness the Prince, His Royal Highnesses the Prince." Fang Xuanling and Wei Zheng heard the shouting and immediately clasped their fists and saluted.

"The two of you are also coming to listen to math class?" Li Chengqian asked with a smile, actually wanting to probe the bottom of his heart.

If they're here to oversee, they can't get distracted in the school.

Otherwise, once they go back and report to Li Shimin, they will inevitably be scolded.

Li Tai and the others also waited for an answer with some expectation.

"Hehe......" Seeing this, Wei Zheng and Fang Xuanling couldn't help but smile at each other. They are all human spirits, where would they not know, the careful thinking of Li Chengqian and others?

But I'm afraid that they will sue me......

"His Royal Highness the Prince, princes, today, Lao Chen and others are also here to listen to math lessons." Wei Zheng replied with a smile.

"Oh...... I see! Li Chengqian breathed a sigh of relief, and then continued, "Then the student won't bother the two ministers, and the class will start soon." ”

"Yes, the two ministers, let's listen to the class together......" Li Tai also said along.

"Yes, Your Highness." Wei Zheng and Fang Xuanling hurriedly clasped their fists and saluted, and then went to the back of the school hall and found a vacant seat to sit down.

This vacant seat was specially arranged by Li Yi for people to observe.

"Jingle Bell ......"

The official class bell rang, and the entire school was silent.

At this point, all students are ready.

Li Chengqian, Wei Zheng and others also waited for Li Yi to appear and start math class.

However, they did not wait for Li Yi to appear, but a small child stepped onto the podium.

I saw him slowly open the textbook, glanced at the students below, and then said, "Okay, students, let's start math class." ”

"Yes!" The students in the school all smiled and nodded, and sat down peacefully.

But Li Chengqian, Li Tai and other princes, as well as Wei Zheng and Fang Xuanling, looked stunned on the spot.

"What's going on?"

"When did the math teacher change?"

"Where's Li Bo'an? Where did that guy go?"

"Isn't it...... He's not coming to math class?"

After hesitating for a moment, Wei Zheng immediately stood up from the auditor's seat, looked at Di Renjie on the podium, and asked with a smile: "Huaiying, what about Li Bo'an's people?" ”

"The student has seen Wei Gong." Di Renjie immediately clasped his fists and saluted, and replied politely.

"The teacher should be in the dean's mansion now."

"Just now, the students were negligent and forgot to say it, and the teacher said that from now on, let the students teach the course of "Elementary Mathematics" to everyone."

After saying this, Di Renjie stopped speaking and waited quietly.

“？？？” Wei Zhengden was stunned and wondered, "You have already learned the course of "Elementary Mathematics"? ”

"Yes, Duke Wei." Di Renjie smiled and nodded, humble and polite.

"Oh......" The corners of Wei Zheng's mouth couldn't help twitching slightly, he turned his eyebrows to look at Fang Xuanling next to him, and motioned for him to come and ask a few more questions.

Fang Xuanling nodded.

He also felt that Li Yi was a bit of a fool to let a child teach.

So, Fang Xuanling immediately stood up, and then asked: "Huaiying, since you have finished studying "Elementary Mathematics", how did Li Boan admit that he asked you to teach other students?" ”

Di Renjie was not nervous.

Maybe in the past, when Fang Xuanling and Wei Zheng asked him like this, Di Renjie's heart would be nervous.

However, after experiencing the last class and yesterday's classroom exercise, Di Renjie's heart is now much stronger.

"Returning to the house." Di Renjie politely clenched his fists and said, "The teacher gave the students a set of test papers, and the students scored 100 points and passed the teacher's test, so the students can teach other classmates math classes." ”

"100 points?" Fang Xuanling and Wei Zheng were both stunned.

Li Chengqian and others were also stunned.

Although Di Renjie is a Chang'an prodigy who went out, they still have some doubts after scoring 100 points in mathematics.

After all, Li Yi's math class is very profound.

They haven't figured out much yet, how can Di Renjie be?

So, Fang Xuanling proposed: "Huaiying, can you show your test paper to the old man?" ”

"Good!" Di Renjie nodded without hesitation, and at the same time opened the test paper in his arms, then took it and handed it to Fang Xuanling respectfully.

"Two ministers, please see." Di Renjie nodded modestly and offered it with both hands.

"Hmm." Fang Xuanling and Wei Zheng nodded to each other, and then looked at the test paper together.

The previous questions are all correct.

The middle, all right.

The following topic......

After seeing half of it, Fang Xuanling and Wei Zheng both frowned, because they found that as far as they were learning, they couldn't answer it at all.

It's embarrassing.

They only saw a red tick on the test paper.

Flipping through the test paper, it reads:

100 points, the children can be taught!

“…… Ahem..."Wei Zheng and Fang Xuanling coughed dryly, then pointed to the last question on the test paper, and said loudly, "Huaiying, this question ...... Also a topic for elementary math? ”

"It's not." Di Renjie shook his head seriously and explained to the two of them seriously, "These two problems are medium math problems. ”

“？？？”

Medium math questions?

This straight thief, no wonder the old men want to break their heads, but they can't solve it.

"This son is worthy of the name of a prodigy!"

Wei Zheng and Fang Xuanling looked at each other and nodded.

"Huaiying, you're already learning middle math now?" Wei Zheng closed the test paper and handed it to Di Renjie, and asked with a smile.

"Well, I'm halfway there." Di Renjie answered honestly.

“……”

Wei Zheng and Fang Xuanling suddenly didn't want to deal with Di Renjie anymore, and the corners of their mouths twitched slightly for a while.

Huaiying, this kid, has even learned half of the "Intermediate Mathematics" course?

We haven't even had time to finish "Elementary Mathematics" yet!

Why is the gap between people so big?

No wonder Huaiying, this kid, can reassure Li Bo'an!
