"Master."

When Tang Ruyi was in a dire study life, she wanted to give up, but also wanted to surpass Lu Xiao, and the whole person was made up, at this time, she felt that no matter who it was, as long as she came to Teacher Hao for something, she could get a little respite by luring her away a little.

When she heard these two words, Tang Ruyi raised her head in surprise, and heard her wish!

The Real Heaven Haotian: ......

Not really.

The false Heaven Luxiao was as expressionless as ever, his eyelids drooping, as if he hadn't woken up.

Hao Jiujiu straightened up and looked at Lu Xiao who was standing outside the door, she smiled lightly: "It's Lu Xiao, is there anything wrong with finding a teacher?" ”

"Come in first."

Lu Xiao nodded silently: "Master, do you have time?" ”

Hao Jiujiu raised his eyebrows slightly, and before he could answer, Tang Ruyi next to him hurriedly replied: "Yes, Yes, Teacher Hao has time." "Hurry up and take your master away!

She looked at Lu Xiao complicatedly, and in the end, it was this guy who came to save herself.

Although he is not a save.

But don't expect her to be grateful to him!

Lu Xiao, who was stared at again inexplicably, lowered his eyelids, it didn't matter, he had never cared about these things, and he wouldn't care about what people who didn't care about.

Hao Jiujiu smiled: "Okay, there is time, but wait a minute." ”

She looked back and got a flattering smile, and then Hao Jiujiu pulled out a stack of test papers from his arms, all of which were the questions she had given to those children before, and now they were considered waste.

"In that case, Ruyi, I see that you have no intention of learning, so this is the end of today's lecture."

These words should have been very happy words, but Tang Ruyi looked at the stack of rolls in Hao Jiujiu's hand, and couldn't be happy, and stiffly pulled out a smile.

It's great that children learn to smile at a young age.

"Then these are your homework for today, and I'll check it tomorrow morning before class."

"Today's?" Tang Ruyi exclaimed.

These test papers are all what she has to do today!!

Tang Ruyi was in shock, and he didn't even realize when this stack of test papers arrived in his arms, revealing a mask of pain.

Lu Xiao glanced at the stack of test papers lightly, and sighed lightly in his heart, what a few.

Master is still merciful.

Tang Ruyi's child was still in shock, out of body, he couldn't care about what was happening around him, and Lu Xiao was not important at this time.

Of course, the two people around her didn't care about her state.

Anyway, it's going to be written anyway.

All resistance is ineffective.

Hao Jiujiu took Lu Xiao back to the office, because the project itinerary over there in the Law Enforcement Hall was in full swing, and the original sweetheart of her good apprentice about her this month suddenly came, so Hao Jiujiu simply adjusted the course during the day slightly.

Let them go over to build houses and swing swords during the day, and use them to practice at night, and the usual classes are compressed to the next month.

So this is also the reason why during the day, there is only Tang Ruyi alone in the classroom.

"Say, Lu Xiao, what is the question you want to ask?" Hao Jiujiu sat on the chair, took a sip of tea, and looked at Lu Xiao.

Lu Xiao took out a piece of paper from his sleeve and handed it to Hao Jiujiu, his voice seemed to slow down twice: "I can't figure out the direction of the formation, after trying a few times, all failed, I went to ask the senior brother, he can't get it for the time being, I have exhausted all the vitality, but it's okay to get it out." ”

Such a difficult formation?

Hao Jiujiu was a little surprised: "You can't get an answer to the discussion?" ”

Lu Xiao nodded, looking a little deflated.

Hao Jiujiu took the blank paper, unfolded it and looked at it carefully for a while, there were some notes written next to the white paper, which were written very carefully, this was just the prototype of the formation, but they were stumped at the first step.

"Master, when the Yuan Qi first drew the formation, it was resisted, and I couldn't draw it, I thought it was because the formation was drawn wrong, and I redrew it later, but it was still the same problem, I tried to look at it from the length of the line and the angle problem, but it still didn't solve the problem."

Regarding professional issues, Lu Xiao has always talked a lot.

And it's very fluent.

After Hao Jiujiu listened to Lu Xiao's words, her eyes returned to the blank piece of paper again, and when she looked at it again, she found something new: "Huh? ”

She raised her eyes to look at Lu Xiao: "You changed the formation?" ”

Lu Xiao's pupils widened slightly: "Can't you?" ”

"Also...... It's not that it can't be done, updating the formation or something, in fact, it's a little difficult for your age, your thinking is right, in fact, the problems you think about are right. ”

Lu Xiao's eyebrows tightened: "What's wrong with that?" ”

Hao Jiujiu raised her eyebrows slightly, she held the white paper between her two fingers, stretched out in front of Lu Xiao, and her white fingertips touched the lines of the formation.

"Look."

The next moment, Hao Jiujiu's vitality skyrocketed, and all of them poured into his fingertips and merged into that formation.

The starlight array gradually lit up, the lines were lit up one by one, very smooth, Lu Xiao's eyes stared directly at this change, and the bright light gradually changed from fluorescent to fist-sized light in his eyes.

As the formation was lit up, the paper slid away from Hao Jiujiu's fingertips like a feather, floating in the air.

In the next second, the formation began to disintegrate, and those lines gradually became larger, stretched, became illusory, sank, and finally merged with the floor.

Suddenly, Hao Jiujiu felt a very mysterious feeling.

"It worked." Lu Xiao muttered.

His eyes were full of surprise.

He immediately turned his head to look at Hao Jiujiu, took a few steps forward, and his voice was anxious: "Master, Master, why?" ”

"Tell me, why?"

At this moment, Lu Xiao's studious heart has reached its peak.

God knows, in fact, he couldn't solve this problem since yesterday, and there is no way to ask Master today.

As a result, in just one or two clicks, the master unraveled.

The child's eyes were full of admiration.

Looking at such a vivid Lu Xiao, it is really rare, Hao Jiujiu's lips hooked up a smile slightly, and she couldn't help but reach out and touch the child's head.

Lu Xiao blinked and tilted his head, but he didn't stop his master's movements.

Hao Jiujiu was thinking about how to talk to the child tactfully.

"Two reasons, the first reason, Xiao'er, you have improved the formation, but when you use the Yuan Qi, you still use the original method."

Lu Xiao blinked, and seemed to understand something in his head, but he was always covered with a thin veil, as long as the wind blew, he could peek into the secret behind it, but unfortunately there was no wind now.

"What is it?" He asked softly.

Hao Jiujiu: "It's the other way around." ”

Ding, Lu Xiao's eyes suddenly lit up.

"Why didn't I think of it, yes, why didn't I think of it, it should be the other way around, when I improved the formation, I removed some cumbersome parts, but this also pushed the entire formation a few steps forward, and it should be the opposite." He muttered.

Today, the four apprentices have a lot of words.

Hao Jiujiu silently commented in his heart.

"Another reason? Master. ”

Hao Jiujiu pondered for a long time, touched his chin, and said slowly: "The improved formation is indeed good, and the power and utility are much better than the previous ones, but have you thought about it Xiao'er, when this formation was first thought out, it was so that people with low strength could also have some self-preservation power." ”

So, it's your strength that isn't enough.

In other words, you're too vegetable.

After finishing speaking, Hao Jiujiu felt that his statement was very good and very tactful, and the child would definitely be able to hear the meaning of his words.

"Low ...... strength"

Lu Xiao lowered his head and began to think about this question.

Low strength = Strength is not good = Formation that can be made by monks who are not strong = Formation can be made by anyone = So the formation he made, those monks can't use it = That's because they are too vegetable.

Lu Xiao immediately figured out this question.

Seeing the child's expression change, Hao Jiujiu really wanted to know what was going on in the child's head, Lu Xiao seemed to her to be a pure science and engineering student, and she didn't know where he would think.

"I see, Master." After Lu Xiao figured it out, he bowed his hand slightly to Hao Jiujiu, and then immediately rushed out.

Hao Jiujiu swore that this was the fastest speed she had seen in Lu Xiao's child.

However, this kid works so hard, Hao Jiujiu is really very pleased.

On the other side, Tang Ruyi, who reacted, looked at the scroll in his arms, looked at the numbers on the scroll, those formulas, and in an instant, he felt sad and began to cry.

Math problems, math problems again!

She really doesn't want to do math problems anymore!

Who invented these math problems, it seems to be the master of Brother Qinghou.

Woowoo...... Then she's really scary!

Brother Qinghou does these questions every day, how can he endure it.

Brother Qinghou is really powerful, but if you are with Brother Qinghou, you have to look at these topics every day, and for a moment, Tang Ruyi feels that Brother Qinghou is not fragrant.

Why torture yourself.

She took out the jade butterfly from her arms and poked Xia Qinghai.

"Second brother, when will you come to pick me up, I really don't want to stay any longer in this Mingyue Peak, I miss you so much."

"Second brother, I don't want to do math problems anymore."

"I think Brother Qinghou is so powerful."

"But Brother Qinghou and I are really not from the same world, and I don't want to do math problems!"

"I hate doing math problems the most!"

"Brother Qinghou's master is so perverted."

In just such a moment, Tang Ruyi had already sent several airtight voices to Xia Qinghai, she waited for some time, and found that the other party did not reply to her message, although she knew that he was busy, but she still felt very sad.

Woowoo...... I'm going to come face to face with this pile of rolls.

It's so uncomfortable!

……

On the other side, Xia Qinghai woke up from his cultivation, and his first action was to touch the jade butterfly in his arms, and the jade butterfly trembled several times.

Xia Qinghai: "??? ”

Who, send him so many airtight voices.

He paddled the jade butterfly, and sure enough, it was Ruyi's sister.

Looking at so many airtight voices sent by the other party, a smile slowly appeared on his face, and then, after listening to these airtight voices, he froze there with the movements of the jade butterfly.

Lost in thought......

Mathematics...... What is it?

Something that sounds scary.

Xia Dad didn't copy all the things that Hao Jiujiu made, for those Chinese and math classes, he didn't understand it himself, if he taught it to the children, they wouldn't be able to learn it, come and ask himself, he can't answer, isn't it a shame and a big loss?

Therefore, what he is currently using is Hao Jiujiu's perverted, very involuted cultivation time schedule.

Xia Qinghai held his jade butterfly for a long time before he sent an airtight voice to the other party: Sister Ruyi, you ...... What exactly is mathematics?

Here, after getting Xia Qinghai's reply, Tang Ruyi instantly threw away the pen in his hand and took out the jade butterfly.

A few seconds later......

She took Jade Butterfly back into her arms with a blank face.

Math, math, how do I know what math is!

Big fool, I'm here to let you comfort me, not to ask me questions!

It's about math.

Bad luck!
