A lively bazaar has been formed outside the gate of Gewu College, the original Shangshui Village has become Sheung Shui Town, the whole town is mainly dependent on Gewu College, more than half of the people in the town are students who come to Gewu College to audit, and the remaining half are mostly traders except for the original villagers.

Speaking of the knowledge taught by Gewu College, although it is different from the Confucianism taught, it has gradually been accepted by the orthodox Confucianism, and even many people are committed to integrating these new studies into the Confucian system, for this approach, Zhao Yan is also very supportive, because this is very conducive to the spread of new learning, for example, some time ago, there were ministers who proposed that Zhao Yan's new learning could be added to the imperial examination, although this suggestion was not adopted by the imperial court for the time being, but at least it also shows the influence of Xinxue.

When Zhao Yan took Zhao Xu to Gewu College, it was just the time when the college opened in the morning, and the market in front of the school was full of breakfast stalls, and the stalls were crowded with students of all ages, most of whom were audit students of the college, because the official students of the college generally lived in the dormitory of the college, and they generally only ate in the cafeteria of the college in the morning.

Zhao Yan's carriage came to the door of the academy, and then he got out of the carriage with Zhao Xu and entered the academy under the protection of the guards, because the academy is the holy land of knowledge, and no one is allowed to enter by carriage here, even if Zhao Yan is the founder of the academy, even if Zhao Xu is the emperor of the Great Song Dynasty, but they must abide by the rules of the academy when they come to the academy.

Three years ago, Zhao Yan began to plan to open a medical department in Gewu College, medicine was originally a very important discipline, so after the establishment of the medical department, Zhao Yan quickly changed the medical department to a medical school. After three years of development, medical school has become one of the most important disciplines in Gewu College, because medicine is not only practical, but also can be examined to become a medical officer, so there are a lot of people who apply for medical school every year.

The medical school is located in the northeast corner of Gewu College, very close to the apparent microscopic of the Daomen. It is the place where Zhao Cheng studied medicine, Cao Tong and Zhilugu also lived there, speaking of which Zhilugu is more than ninety years old, but because of his good health, he is still strong and strong, not much worse than young people, it seems that he will live to be a hundred years old It is already a sure thing.

Zhao Yan had also been to the medical school a few times before, so he was relatively familiar with this place, and he took Zhao Xu directly to Zhao Yan's office at the moment. Then he pushed the door in without knocking on the door, but he just saw Zhao Hao bowing his head and writing something, and when he heard someone coming in, he didn't even raise his head and said, "Third brother, when will you learn to knock on the door?" ”

"Huh? Fourth Uncle, you didn't even look at us, how do you know that the third uncle came in? Before Zhao Yan could speak, he saw Zhao Xu and asked first with a curious expression.

"It's simple, someone from the entire medical school who dares to enter my office without knocking. Except for your fourth aunt, there is only your third uncle, but your fourth aunt is pregnant. During this time, I was raising a baby at home, and it was impossible to come to the college, so naturally it could only be your third uncle. When he said this, he saw that Zhao Hao finally put down the pen in his hand, and then raised his head and smiled at Zhao Xu, "Of course, the above is not the point. The point is that your third uncle has already told me before that he is going to bring you here today, so I can naturally judge who is pushing the door in at once. ”

"I see, I thought Fourth Uncle you had the ability to predict the future!" When Zhao Xu heard this, he laughed and joked, although Zhao Xu was more than ten years older than him. But Zhao Xu's personality is witty, and he usually gets along with Zhao Xu's nephews, so Zhao Xu is not afraid of Zhao Hao, and naturally has to make a few jokes when they meet.

"What is an uncertain prophet, your fourth uncle and I don't want to learn the Tao, otherwise, if you learn some Taoist techniques from the Daomen, the unpredictable prophet is not rare at all, and even the art of spreading things into soldiers is not a problem!" Zhao Hao was also joking at this time.

"Hehe, don't say it's a joke, let's start class next, I have other arrangements in the afternoon!" Zhao Yan also smiled at this time, and at the same time winked at Zhao Yan a little dirty.

Seeing Zhao Yan's expression, Zhao Yan's originally smiling face couldn't help but stiffen, and he said to Zhao Xu at the moment: "Your Majesty, you go to the next room and wait first, and I'll give you a lesson when I'm ready!" ”

"Hmm!" Zhao Xu agreed very obediently, and then turned to the next room, which is actually a small conference room, where Zhao Xu usually holds meetings for the teachers of the college, and there is also a small blackboard next to the table, which can naturally be used as a classroom.

"Third brother, do you really want to give such a lesson to Your Majesty?" After Zhao Xu left, Zhao Yan immediately asked Zhao Yan with a bitter face, when Zhao Yan talked to him about this a few days ago, he thought that the other party was joking, so he didn't take it seriously and agreed, but Zhao Yan has been urging him to prepare for class in the past few days, which made him understand that this is not a joke, but it is too late for him to regret it.

"Of course, Xu'er's age is not young, some time ago he actually asked to replace the old palace maid next to him with a young and beautiful woman, which shows that he has begun to be interested in the opposite sex, so we have to guide him correctly now, as a doctor, no one knows this aspect better than you, so this matter can only trouble you!" Zhao Yan said with a natural expression.

"You don't know this kind of thing less than I do, why do you have to let me talk about it?" Zhao Yan secretly slandered himself at this time, of course, he didn't dare to say these words, because Zhao Yan was not only his third brother, but also his teacher, although he had already left the school, but he still had a natural awe for Zhao Yan in his heart, especially this matter he took the initiative to promise, so he couldn't regret it at all.

In desperation, Zhao Xu took out the prepared lecture plan from the table, and then glanced at Zhao Yan with resentment, and then slowly entered the conference room next to him, at this time Zhao Xu was already sitting in his seat, looking at Zhao Hao curiously with a pair of big eyes, today's class seems to be particularly mysterious, so he is also full of interest in this class.

Under Zhao Xu's gaze, Zhao Xu's face turned red rarely, and he even had an urge to turn around and run away, it was not the first time he had taught this kind of class, and he had taught similar classes to students before, but Zhao Xu was his own nephew, which made him really a little unable to wipe his face, but when he thought that Zhao Yan was still outside, he could only bite the bullet.

At that moment, I saw Zhao Hao walking quickly to the small blackboard in the conference room, then took out a picture from his lesson plan, and then hung the picture on the blackboard and opened it. However, when Zhao Xu below saw the content on the picture, the expression on his little face was stiff, and then he glanced at his fourth uncle strangely, because there was a man and a woman painted on the picture, and they were not wearing clothes.

What Zhao Hao wanted to teach Zhao Xu was a physiology class, even in China in later generations, many schools did not open this kind of class, and even if it did, most of the teachers who taught the class were fooling things, either letting the students see it for themselves, or simply skipping this class, so Zhao Yan's decision to give Zhao Xu a physiology class was indeed a little too advanced.

"Ahem~, Your Majesty, today I will teach you this physiology lesson, the so-called physiology, broadly speaking, refers to the life activities of biological organisms and the functions of various organs, but it also has another meaning, that is, the principle of growth and reproduction......"

Zhao Hao is a doctor after all, although it is a little awkward to teach this physiology lesson to his nephew, but he has also taught similar courses to students before, so after letting go, his words became very fluent, and he began to talk in detail about the differences in the physiological structure of men and women, as well as the mystery of growth and reproduction.

Although Zhao Xu is not yet eleven years old, he has been precocious since he was a child, which makes him a little vaguely curious about the affairs of men and women, in fact, this situation like him is not uncommon among aristocratic men, and even some eleven or twelve-year-old aristocratic men have already handed over the maids by their side for the first time, and some even have children.

In contrast, Zhao Xu was relatively pure under the strict defense of the Empress Dowager Gao, and when he heard the fourth uncle talk about these men and women, he was still a little red at first, but slowly he was also infected by Zhao Hao's calmness, and began to treat these as an alternative knowledge, and began to listen seriously.

Zhao Yan knew that Zhao Hao's lecture would not be finished in a while, so he didn't wait, but went out of the Gewu Academy again, came to the market outside to buy some snacks, and then returned to Zhao Hao's office to eat and wait, and waited until he had eaten the snacks almost, only then did he see the door of the conference room open, and then saw Zhao Hao walking out with the lesson plan, followed by a thoughtful Zhao Xu.

"Fourth brother, how is the class?" Zhao Yan asked with a smile while holding a pine nut.

"This kind of class is not difficult in the first place, third brother, you can see the expression on His Majesty's face, you know that he has gained a lot today." Zhao Hao also smiled at this time and said, he now regards Zhao Xu as an ordinary student, so naturally there is nothing to be embarrassed about.

However, Zhao Xu is still an untrained child after all, and when he heard Zhao Yan's question, he couldn't help but blush, and then lowered his head and didn't dare to look at Zhao Yan, Zhao Yan also knew that children of his age were also more sensitive, so he didn't ask Zhao Xu how he studied alone, after all, Zhao Xu was not going to study medicine, and he only needed to understand these aspects of knowledge.

At that moment, Zhao Yan and Zhao Hao chatted a few more words, and by the way, they asked Ya'er about the situation after she became pregnant, and then she took Zhao Xu out of Gewu Academy, he had another class to take in the afternoon, and compared to the physiology class in the morning, this class in the afternoon was quite heavy.
