It is a question of a history course, and Tang Wan asked Ma Xiaochuan to tell the time of the change of dynasty and the dynasty.

After hearing this, Ma Xiaochuan said without thinking: "The first real dynasty in China was the Xia Dynasty, which was established about 2070 BC and was founded by Qi ......."

Tang Wan's face was relatively calm at first, and the Chinese Historical Dynasty Replacement Table was not a difficult task for students who used a little bit of care.

But it didn't take long for Tang Wan's expression to gradually solidify, and a little surprise slowly appeared in her eyes.

Because what Ma Xiaochuan recited was not only the dynastic chronology table, from the beginning of the Xia Dynasty to the end of the late Qing Dynasty, the time of each dynasty change was accurate, and he also casually said some representative events that occurred in these dynasties.

And the causes, results, main characters, and background of these events were clearly explained!

It took more than ten minutes for Ma Xiaochuan to sort out the 5,000-year history of China clearly!

"That...... Do I have flowers on my face?"

After Ma Xiaochuan finished narrating, he suddenly found that Tang Wan was staring at him intently.

"I didn't write a lot of knowledge in my notebook, where did you ......come from," Tang Wan relieved from shock.

Ma Xiaochuan said casually, "Oh, you said this, it's very simple, your chronological replacement table is very accurate, when I memorize this table, I refer to the textbook, and by the way, the important historical events of the relevant era are also incorporated, and then expand this table into a tree chart, and then write down this tree chart." ”

This was said easily, but Tang Wan's expression was even more shocked, Ma Xiaochuan said that this method of learning history is not new, but it takes a lot of time to complete, could he really use it overnight......

"Then I'm asking you, geographically, the climate of the Northern Hemisphere ......"

Tang Wan said another question about geography, and Ma Xiaochuan spoke again for more than ten minutes, following Tang Wan's question, making an extension of the knowledge points, and sorting out the climate characteristics of the entire earth clearly!

Tang Wan couldn't believe her ears, the questions were getting more and more difficult, and the speed of flipping through the notebook was getting faster and faster.

But no matter how difficult the topic is, Ma Xiaochuan almost doesn't have to think about it every time, and blurts out directly, the answer is accurate, and he makes a very rigorous extension through this knowledge point.

Half an hour later, a layer of fine beads of sweat had oozed from Tang Wan's head.

"Is there anything else you want to ask?" Ma Xiaochuan looked very calm.

"No ..... no ......"

At this time, Tang Wan no longer had the slightest doubt about Ma Xiaochuan's mastery of the knowledge points in this notebook, but she couldn't figure it out in her heart, even if she worked hard to memorize it, she would definitely not be able to do it for more than half a month.

But this guy only remembered that it took one night to remember that the melon was ripe, and he also made a huge horizontal extension of every knowledge point, which is a bit too ..... terrifying!

"Did you really spend a night jotting down these things?" asked Tang Wan incredulously.

Ma Xiaochuan scratched his head a little embarrassed and said with a smile, "It's not all, it's not all, it's taken a little effort to endorse in the past few days, and combined with the context sorted out in your notebook, it constitutes the knowledge points I just mentioned." ”

Tang Wan was even more shocked after hearing this, and said with wide eyes: "You mean, you have studied all the textbooks in the past few days?"

"yes, anyway, I'm idle and have nothing to do, so I'm just watching and playing. Ma Xiaochuan smiled, he didn't actually have the slightest intention of being pretentious.

He had long been accustomed to his strengthened brain, so it was normal for him to do these things, but he ignored how shocking it was for an ordinary person!

Tang Wan felt incredulous, but she also did not doubt the authenticity of Ma Xiaochuan's words, she and Ma Xiaochuan have been in the same class for more than two years, and she knows very well what Ma Xiaochuan studied before.

"But I'd like to make an observation. ”

Ma Xiaochuan said suddenly: "Your notebook is really good, but I feel that it is a bit blunt in the Chinese section, such as ......."

While speaking, Ma Xiaochuan spread out the notebook and explained the knowledge points of the language section above, "Classical Chinese should be a kind of smart charm, the textbook is just a reference, the meaning will always be greater than the words, the approval you made on the above is too decent, if you understand it this way, it is difficult to appreciate the artistic conception ......"

Wenyan happened to be Tang Wan's shortcoming, so she listened carefully, Ma Xiaochuan said these methods, she had never thought of before, after listening to it, there was a feeling of a long drought and a rainy day, and many places suddenly became clear.

Inadvertently, he glanced sideways, and happened to see Ma Xiaochuan's side face, at this time he was seriously explaining the knowledge points in the notebook, and the soft light just shone on his face, looking at it from this angle, Tang Wan suddenly felt that Ma Xiaochuan was actually quite handsome.

And Ma Xiaochuan was fully engaged in the knowledge above at this time, but he didn't notice the careful thinking of the girl next to him at all.

"Xiaochuan, I'm going to say I'm sorry to you, I misunderstood you yesterday. ”

Tang Wan smiled at Ma Xiaochuan, "And I can't run circles with you, Teacher Zhang asked me to set up a study group, starting tomorrow, every day after self-study, I will take the members of the study group to study." ”

The third year of high school has heavy learning tasks, and although the sports day is important, it must also make way for learning.

Ma Xiaochuan nodded understandingly, "It's okay, learning is important, don't worry, I will go to the lap by myself, and I will ensure that the sports meeting will not hold back the class!"

"That's okay, I believe in you, if you need any help in the future, come to me at any time!"

Tang Wan said with a smile, and then the two walked out of the classroom together, and when they separated, Tang Wan stood silently in place for a long time, until Ma Xiaochuan's back completely disappeared into the darkness, she exhaled softly, and then turned around and slowly walked towards the girls' dormitory.

When she was on the road, Tang Wan's mind was full of Ma Xiaochuan's side face under the light, and she thought to herself, what kind of person is this guy?

At this time, Ma Xiaochuan didn't take what he had just done to heart, and he didn't feel sleepy, so he came to the playground to run laps alone.

Since returning to this time and space, Ma Xiaochuan found that his physical body was still very weak, and it could not be compared to his physical body in the other world that had been tempered countless times by true qi.

In the running lap, he tried to use his true qi, and immediately stepped into the wind, he wanted to test what kind of physical limit his physical strength was in this time and space.

So he directly used all his strength, running around the playground at a speed of 100 meters for seven or eight laps, until the true qi in his body was exhausted, he stopped, and leaned down to the side and gasped for breath.

I took out my phone to check the time, but suddenly saw several missed calls, all from the same unknown number.

Ma Xiaochuan thought to himself who would be looking for him so late, and was about to call back, when he suddenly heard a voice from the side, "Ma Xiaochuan!"

After turning his head to see the person who came, Ma Xiaochuan suddenly frowned.

"I haven't seen you for a long time, I heard that you have a good life these days?" spoke a young man with a hedgehog head, holding a cigarette in his mouth obliquely, with his hands in his trouser pockets, a standard bad boy.

"I said, stay away from me in the future. Ma Xiaochuan was upset when he encountered these things now, and he didn't plan to pay attention to the other party at all, and was ready to turn around and leave.

But the man was determined to get along with Ma Xiaochuan, so he chased after him in a few steps and stopped in front of him, tilted his chin and looked at him with a provocative expression.

"Haven't you been beaten enough in the classroom last time?" A chill flashed in Ma Xiaochuan's eyes, this person was the hedgehog head he had cleaned up in the classroom a few days ago.

The hedgehog head had disappeared for several days since that morning, but I didn't expect it to be here today.

The hedgehog head snorted coldly, "I heard, you kid is quite capable, even Zhang Hai was cleaned up by you, I can't see it!"

"What the hell do you want to do!" Ma Xiaochuan replied to the other party's gaze.

"That's not the end of the day in the classroom!"

The hedgehog head suddenly raised his head, glared at Ma Xiaochuan angrily, and said, "This matter must be decided today!"

"Then what do you want to do?" Ma Xiaochuan felt a little headache, he really didn't want to cause trouble, but why did these people always pester him like flies?

"Let's go one-on-one!" the hedgehog clenched his fist.

Ma Xiaochuan was speechless, if he did it, ten hedgehog heads tied together would not be enough for him to play with one hand.

It's just that treating this person is different from cleaning up Zhang Hai and others, Ma Xiaochuan would rather offend a few more characters like Zhang Hai, and he doesn't want to be easily tied by a hedgehog head.

It's not how powerful the hedgehog head is, his reputation in school is far less than Zhang Hai, but he is a very individual person, he is always alone on weekdays, and it is rare to see him get closer to anyone.

Other thorn-headed students are in groups of three or five, but the hedgehog head is different, he never gets together with people easily, but he is a character that even Zhang Hai doesn't dare to provoke easily.

His fist and foot skills are average, but he has the ruthlessness of an outlaw, and it is particularly difficult, no matter how badly he is beaten, as long as he is not killed, this kid will never give up.

When he was a freshman in high school, the hedgehog head had a conflict with a group of people who were in the third grade of high school at the time, and the group of people beat the hedgehog head to the hospital.

But this matter is not over, after being discharged from the hospital, he hides a stick on his body every day, as long as the group of people have a bill, they immediately rush up to be a mess.

The group also fought back at first, and the hedgehog head was beaten badly every time he succeeded in a sneak attack.

But later, the group suddenly took the initiative to treat themselves to compromise with the hedgehog head.

Why?

Because the grandson of the hedgehog head is simply not a thing, just like the stone in the pit is smelly and hard, no matter how many beatings he receives, he will never admit it.

Later, the gang became suspicious one by one, and never dared to put orders easily, even squatting in the toilet had to prevent a stuffy stick from being smashed on the top of their heads.

The hedgehog head put down the cruel words: "Either kill me, or you guys don't think about it!"

In the end, the group finally confessed, and the hedgehog head became famous.

So dealing with a person like a hedgehog head can't be solved by beating him badly, but you can't really kill him!

"Wait!"

Seeing that the hedgehog head was about to rush up, Ma Xiaochuan hurriedly shouted, his mind moved, but he had an idea, looked at the hedgehog head and said, "Hedgehog, let's play something else today." ”
