"Chapter 3?"

Gong Sinan narrowed his eyes into bright slits in dissatisfaction.

"Yes, it's a guarantee that we won't cause trouble to anyone else, and you won't be caught doing strange anatomical studies." Yi Cheng said seriously, "Because you have to be by my side, I have to take you to school."

Number one, you have to hide in my pocket whenever a third party is present. At the same time, so that your body does not swell, I will give you ice cubes.

As long as the temperature remains constant, you will be able to maintain a stable size. ”

Gong Sinan tilted his head stubbornly.

"Why should I agree with you as a mortal...... Ahahaha......"

She was rubbed back and forth by Yi Cheng with his fingers on the table.

"Well, I'm reluctant to agree to the first one." The goddess duck sat on the table and stretched out her hand to Yi Cheng, "Servant, come to me, I'm cold." ”

Yi Cheng frowned and shook his head, helplessly handing her his hand.

The goddess grinned and climbed onto his palm.

"Second, in the presence of any third person, you must not make a sound, and you must not expose yourself to being seen by others."

"Hah, stupid." Gong Sinan snorted contemptuously, "Do you think that with my powerful aura, as long as I don't speak, I won't be discovered...... Ahahaha......"

Yi Cheng rubbed the noodles back and forth.

About ten seconds passed.

The goddess sat up again with her hair disheveled.

"Well, in that case, then I can only barely hide my terrifying aura."

"Third, even if you are at home and you return to the normal size of a human being, you can't press me casually, and you have to put on clothes and can't talk nonsense."

"Idiot, where did I get my clothes?!"

"Wear my aunt's." Yi Cheng said, "You are about the same height, and you should be about the same size." ”

How much difference can there be between a flat plate and a double A?

"Wait until I get the physical ......," the goddess smiled sadly.

So he was pressed on the table by Yi Cheng and rubbed again.

“…… I obeyed, servant. Say whatever you say. The goddess hung her head in frustration.

……

"Good." Yi Cheng nodded, "So what do you do now?" ”

"It's just the two of us now, of course...... Hey, hey, hey......"

"Come in."

Yi Cheng pulled out the pajama pocket.

"Why?!" The goddess pouted dissatisfiedly.

"You forgot, third party, my aunt is still there." Yi Cheng said.

"Your aunt is right, you're a bad silver."

Gong Sinan drooped his head, and then waited for him to put himself in his pocket.

"Ah...... Warm breath. ”

She opened her arms and grabbed Yi Cheng from her pocket.

Immediately afterwards, Yi Cheng put a small piece of ice cube in a small box and put it in the palm of her hand.

“emm…… I'm afraid of the cold. ”

"Bear with me." Yi Cheng said.

"Okay."

Gong Sinan hugged the ice cube and then pressed his face against his body.

Ah, what a contradiction.

Localized fever, localized chills.

Hey?

The goddess suddenly raised her head.

She realizes a terrible problem -

If Auntie had been at home all the time, wouldn't she have a time to grow up at all?!

……

After solving the hidden dangers, Yi Cheng finally opened the door and walked out with confidence.

He walked to the living room and saw a strange scene—

My aunt stood in the hallway, hunched over, and pressed her hands and feet against the door.

Outside, a familiar face can be faintly seen.

Bai Jingxue was also using the same posture, trying to come in from the outside.

"Sister Leyin, what are you doing......

"Hmm......" Shen Leyin increased his strength, "You go back, my family Yicheng really doesn't ......"

"What are you doing?" Yi Cheng walked over.

"Ahhhhh......h

Auntie was messy for a while.

She winked at Yi Cheng.

"You idiot, I'm saving you!"

"What the hell?" Yi Cheng was confused.

"I heard Yi Cheng's voice, Ah Cheng, open the door quickly." Bai Jingxue called out happily.

"How can anyone embarrass a guest like this?" Yi Cheng dissatisfiedly pulled his aunt to the side.

Shen Leyin's face was like ashes, and he covered his face in pain.

It's over, it's over.

This idiot.

Auntie is helping you.

If the female ticket that Jing Xue saw you ......

Mommy.

This is the legendary Shura Field!

"You're doing it yourself." The aunt patted him on the shoulder earnestly.

In her eyes, Yi Cheng was already a dead man.

Although there is a lack of rattan characters, she can already foresee the end of Ah Cheng being hacked to death.

"Neuropathy."

Yi Cheng complained and opened the door.

"Hee-hee."

Bai Jingxue walked in and held the raincoat in her hand.

"Where do you put your raincoat?"

"You put the bathroom first." Yi Cheng said.

"Okay."

Bai Jingxue trotted into the bathroom.

"Ah Cheng, my aunt is going to catch up with the manuscript, don't come to me if anything happens later, do you know?"

"What can happen?" Yi Cheng glanced at her angrily.

The aunt walked towards her room step by step with a dead face.

"Have you been bleeding a bit badly lately?"

"I'm sorry, I'll wash the clothes myself." Auntie waved at him, "Take care of yourself." ”

“……”

Is it so strange for anyone to be a writer?

Yi Cheng shook his head helplessly.

……

"Okay, I've got it."

Bai Jingxue walked out of the bathroom, wiped her hands dry, and then took out a piece of white lover from her schoolbag and handed it to Yi Cheng.

"Chocolates that my dad brought back from a business trip to the East Island."

"Hmm."

Yi Cheng tucked the chocolate into his pajama pocket.

But he thought about it, and before the guy could tear the package, he quickly took it out and put it in the other pocket.

"This man is terrible."

The goddess clasped her hands and sat angrily in his pockets.

"I don't know a few math problems, so I'll ask you." Bai Jingxue said as she unloaded her schoolbag from her back.

"Okay."

The two of them came to Yi Cheng's room.

Yi Cheng moved a chair for her, and the two of them sat down.

Bai Jingxue took out the notepad and put it between him and herself.

It was filled with dense notes.

I can see that this guy has been working hard lately.

"Let's take a look at this first." Xiaobai said, taking a bite of chocolate.

[It is known that the sequence {Xn} satisfies X1=1/2, Xn+1=Xn+Xn^2/n^2, which proves that X2001 is less than 1001]

"Well, that's a good proof."

Yi Cheng glanced at the title and said.

Bai Jingxue glanced at him, eager to poke him to death with a pen.

When the goddess heard the question, she folded her hands and let out a soft snort of disdain.

Sure enough, it's a mortal, such a simple question, elementary school students will do it.

"There are many simple proofs, the first of which is calculus."

Yi Cheng explained to her, "Because calculus is fast and rough. The key to this problem is to prove that Xn+1 is less than (N/2)+1. As we can see from the title, this is a monotonically increasing bidirectional function, and it is most appropriate to prove it by finding the limit. ”

"In addition to that, it's good to use mathematical induction......"

After Yi Cheng finished speaking, he picked up the pen and wrote:

……

The aunt was a little worried about the current situation of the Shura Field, so she quietly got up and hid by the door to take a look.

I was taken aback by this.

Yi Cheng and Bai Jingxue elbowed each other, and the two of them seriously discussed math problems.

She opened her mouth wide in surprise, she had never seen such a happy Shura field.

Hey, by the way, what about the classmate named Gong Sinan yesterday?
