Back at Chen Jiao's rental house, he cautiously opened the door, for fear of waking Chen Jiao, after all, it was late at night.

I slept in the living room and clothes, and was woken up in the middle of the night, so I had no choice but to secretly try to open the bedroom door, but fortunately Chen Jiao didn't lock the door.

Quietly put the quilt on the bedroom chair on the ground, Chen Jiao heard the noise, muttered something in her mouth, Shang Tian thought it had woken her up, and listened carefully, it turned out that she was talking in a dream, this woman actually slept so deeply, she wouldn't know if a thief came in.

In the morning, Chen Jiao woke up first, went out to wash with hazy eyes, Shang Tian tossed and slept like a dead pig in the middle of the night last night.

Suddenly, there was an "ahhh

Shang Tian was awakened, and when he opened his eyes, Chen Jiao listened to the phone last night and thought that Shang Tian would not come back, so according to his usual habits, he did not sleep in pajamas, but only wore a pair of pants, and then suddenly found that there was a person on the ground.

Covering his chest with his hands, he fixed his eyes on Shang Tian, "Aren't you coming back, why are you here." ”

As he spoke, he jumped onto the bed and wrapped himself in the quilt.

"That...... I came back in the middle of the night. ”

"Why don't you say a word, you still look, turn your back."

Shang Tian was reprimanded, looking at what he shouldn't see, he also turned his head knowingly.

After a few seconds of stalemate, Chen Jiao calmed down her anger and comforted herself in her heart, "He was unintentional, he was my student, it's nothing." ”

But the little heart still puffed, "Help me hand over my underwear and pajamas." ”

Shang Tian leaned sideways and held the scented underwear with his fingers, and handed it over with his back to Chen Jiao.

The sound of squirming and dressing, everything went on in silence.

Finally, Chen Jiao opened the conversation, "That, remember not to come back too late in the future, you will catch a cold on the ground when you sleep." ”

In my heart, I blamed myself for why I didn't sleep in pajamas, and I didn't know if it would have a bad impact on Shang Tian's growth.

She seems to treat herself as an adult, and treats Shang Tian as a child, if Shang Tian knows her thoughts, she can only say that this homeroom teacher is really too simple, if she meets other students, she doesn't know how she will be lewd, she is in college, and she treats her students as children.

Shang Tian snorted, and Chen Jiao changed the topic, "Did you use some cheat to do your homework yesterday and searched for the answer on the Internet?" ”

The topic changed, Shang Tian also breathed a sigh of relief, and replied: "Isn't it a waste of time to search for answers to that kind of question?" ”

Chen Jiao smiled in her heart, "How many catties and taels do you have, my teacher who has taken you for three or four years is not clear, you are used to bragging in class yesterday." ”

"Waste of time, you think you will do it faster than searching for answers, okay, I don't embarrass you, I watched you do today's homework, if you do well, I believe you." Chen Jiao was already dressed, got out of bed, and motioned for Shang Tian to perform live.

Shang Tian shook his head helplessly, the people of this world are really stupid to mathematics, I don't know how modern science and technology develop, but when he thinks of the mathematical level of foreign people on the earth before, but science and technology are still developing, he also thinks that science and technology may rely on some powerful mathematicians, and other levels are normal.

"Okay." Shang Tian had no choice but to go out with him.

Chen Jiao had already prepared some slightly more difficult questions last night.

Without thinking, Shang Tian used a simple algorithm and finished it in a short time.

This time, in order not to make Chen Jiao suspicious, Shang Tian wrote out every step of the simple algorithm.

Chen Jiao on the side looked shocked and dropped her jaw, "My God, what kind of algorithm is this, the speed is so fast, and he wrote the answer without thinking about the result of the multiplication step in the middle." ”

Chen Jiao, who didn't understand, thought about it, it must be that this guy has no cheat, writes blindly, and wants to get by.

"Don't think that if you calculate quickly, you must be right, look at your steps are messy, I'll answer correctly, you are probably wrong, and you dare to say that you didn't use network tools yesterday."

The questioning Chen Jiao took out the answers in her hand and got them right one by one.

"Hey, I got the first few questions right."

Continuing to look down, Chen Jiao's expression became a little unbelievable.

"What's wrong again?"

After finishing it, Chen Jiao couldn't help but swear words, ", it's all right." ”

Is this true, such a fast speed, even if you can't do it yourself, how did this student who has always lagged behind do it?

The point is, why don't I understand these steps?

Chen Jiao thought of countless explanations in her heart, but none of them were reasonable.

He looked at Shang Tian with a scrupulous look, could it be that this guy has always been hidden, but his courage is not lying, it is still red.

Shang Tian raised his head and looked at Chen Jiao: "I can wash up." ”

The sound of the water in the bathroom did not disturb Chen Jiao's thoughts, and she studied Shang Tian's solution as if she were meditating.

As soon as Shang Tian came out, Chen Jiao leaned over, "Classmate, did you go to which training class?" ”

There are training courses on the earth, and it is the same here, not only tutors, but also training courses, and even some training courses have better education quality than regular schools, such as Tianjiao Training Group, Glory Invincible Training Chain School, etc.

"Training class?" Shang Tian shook his head, the money he made in his predecessor used to live and send it home, where did he go to any training class.

"Have you been taking your medicine for the last few days?" Chen Jiao asked.

She speculated that Shang Tian might have drunk a lot of high-grade potions, increased his counting qi, and improved his computing power.

Shang Tian shook his head, "No." "I haven't had time to find someone to refine the spar I bought, and I have only earned my own money, and I haven't had time to buy the potion, besides, I have to send it home to my mother."

Could it be that he suddenly opened his mind, and his strength has not had time to break through?

Since he couldn't figure it out, Shang Tian didn't tell the truth he wanted to hear after interrogating him for a long time, Chen Jiao just wanted to figure out what was going on with these algorithms.

Shang Tian didn't have any disgust with this head teacher, and he still had a little good feeling, so he didn't want to hide it, he used a simple algorithm to show her when he did the question, and he also wanted to help her, so he patiently explained the simple algorithm to Chen Jiao.

Chen Jiao listened with relish, and was startled from time to time, "Ah, how else can it be calculated?" ”

Excited, she couldn't help but pat Shang Tian's face, "How did you come up with it, you're so smart?" ”

completely regarded Shang Tian as a familiar and cute little brother, and he loved it more and more in his heart.

"Ah, where did you learn the law of union and the law of distribution, you saw it in the library?"

"It's just a pattern I've discovered."

"You found it yourself?"

"yes."

"I want to verify his correctness, maybe it's just these questions that are correct, and the other questions will be wrong when I use them?"

After verifying a few similar questions, Chen Jiao found that it was really a hundred tests.

Her expression changed when she looked at Shang Tian, "I think you must be a genius of several realms, but why have you been so poor in your studies in the past few years?" ”

When asked about the idea, Shang Tian could only make up a random reason, "A few days ago, when I was exercising, I accidentally bumped into the school fitness equipment - the horizontal bar, and suddenly felt that the problem I couldn't do before came to mind, and it was solved in an instant, and in the case that I was not strong, the operation was effortless, especially yesterday in class, obviously I was telling the truth, and those classmates laughed at me and wanted to take me away from me, so many things happened." ”

This explanation is difficult, but Chen Jiao can't think of any better reason, so she can only believe, "Hitting the horizontal bar with your head can increase your qi?" ”

She remembered that a few years ago, an educator from Kyoto inspected the development of the school, walked there and played a few horizontal bars, and said, "Everyone should combine work and rest, and you can't study all day, and you can exercise from time to time to enhance your brain power. ”

Could it be that Shang Tian insisted on the horizontal bar exercise every day?

That one sentence that the educator said plainly was actually a secret book for several cultivations?

Suddenly, several people around were surging, wrapping the two of them, and the entire rental house shook.

"Ahh Chen Jiao shouted.
