Late at night, the hero put down the brush and looked at the dense ink words on the paper in front of him, feeling more tired than studying all night before the college entrance examination in his previous life.

The Pythagorean method is not difficult, and even if he can't fully remember what he learned in middle school, he can come up with new ideas by using the formula to deduce.

However, to describe the formulas, figures, symbols, and letters in his mind in the current words has become a rather head-scratching project, and he can even imagine his brain cells dying in batches, one after another, in a tragic scene.

It seems that the advent of Arabic numerals and various symbols should be put on the agenda.

Why was the illiteracy rate so high in ancient times? In addition to the limited conditions, the content of the textbook is too difficult to understand and not simple enough.

It's a pity that Middle-earth is not the earth, the history is different, and there is no way to take the "Thousand Character Text" and "Three Character Classic" out to enlighten the child like the predecessors did, "Hundred Family Names" is barely possible, but the hero has not memorized it, not to mention the "Disciple Rules", it is too long.

By the way, there are also standard scale rulers, triangular rulers, and compasses, which you have to figure out when you go back.

Stretching a long lazy waist, the hero got up, and when he saw that Jia Qiao was already lying on the couch and falling asleep, he couldn't help shaking his head and laughing, and went over to pick up the girl.

Jia Qiao didn't wake up, but naturally put his face close to the hero's chest, allowing himself to sleep more comfortably in his arms.

Little girl, you serve the young master during the day, and it is the other way around at night. Lao Tzu is also cheap, and I can't get used to so many maids arranged by my mother, but I like you.

Stinky girl, you can't be taken away by the little white face one day, the young master will die of sadness!

Put Jia Qiao on the bed and cover the quilt, and when the hero saw the copper kettle dripping, he turned out a set of night clothes from the burden and changed it.

This is what he prepared in Shuangzhou, not to make trouble in the school palace, but to think that after having the star and moon disk, he will probably often become a woman, carry a set of night clothes with him, and be prepared.

By the way, there is a strip of black cloth in this set of clothes, which is one foot long and one foot wide, which is specially used to wrap around the body.

That's right, he's a big man, and he has prepared a chest wrap for himself......

Who made him so big after he became a woman?

Equipped, he blew out the candles, pushed open the door, and disappeared into the night like a black cat.

About a quarter of an hour later, the door of a fine house in the women's dormitory opened silently, and a slender black shadow flashed, and was about to pounce on the shadow in the opposite corner, when he suddenly stopped and looked vigilantly at a plane tree not far away.

"I knew that whether I agreed or not, you would go."

The hero came out from behind the tree, his tone full of helplessness.

The black shadow covered his face, his exposed eyes were bent into crescents, he walked over with his hands behind his back, and looked at him with his face raised: "Since you know, why didn't you just promise me at that time?" ”

The hero sighed: "Until just now, I was expecting to wait here for a night. ”

The black shadow shook the ponytail at the back of his head and took his hand: "Let's go!" I've already inquired, and the guards of the treasure house tonight are two students from the middle class of martial arts, and their strength is no more than four grades. ”

This black shadow is none other than Su Yanyan.

"By the way," she paused again, looked around, and whispered, "Fauber didn't follow you, did he?!" ”

The hero shook his head: "The star-moon disk has no induction. ”

"Then let's go, go and go back quickly."

Su Yanyan pulled the hero and ran along the shadows of the house.

The girl's hands were cold, soft, as if they had no bones. The hero followed her, occasionally with strands of hair brushing his face in the wind, and he tried to raise his hand to block it, but never took action.

The palace was built on a mountain, and the treasure house was not far from the top, and the two of them rushed all the way up, occasionally stopping to avoid the student servants who were patrolling the night, and after about half an hour, they came to a courtyard.

The hero looked up at the full moon in the night sky, stared at Su Yanyan's eyes and said, "The moonlight is beautiful tonight, it's good to come out for a walk, it's still too late for us to go back." ”

"It's all here, you tell me to go back?" Su Yanyan's eyes widened, "Big brother, are you here to admire the moon?" ”

"I wish I had come to admire the moon."

The hero smiled, his body suddenly became shorter, and he had changed to a woman's state. "Come in!"

Su Yanyan disappeared in an instant.

Pulling the taut chest wrap, the hero took a few deep breaths and muttered, "Why do you enter the Star and Moon Disk with your clothes?" It's not scientific. ”

"How do I know? What is science? ”

"A rebel son of theology."

“…… You always have a lot of this inexplicable weirdness. ”

The hero shook his head: "How to get in?" ”

"Go through the gate."

The hero walked along the wall to the courtyard gate, "The wall is not high, why don't you just climb over it?" ”

"There's an enchantment on it, and it's connected to the entire school palace enchantment. According to my father, under heaven and man, no one can break it. ”

"You don't really want to come here to steal something, do you?!"

"I like to hear my dad tell stories about his youth, don't you?"

"Okay, dad is yours, of course what you say."

Fighting with his mouth, the hero came to the gate, and when he raised his eyes, the plaque on the door read the word "Gongzang".

In fact, this is not only the treasure house of the school palace, but also the library pavilion. To put it bluntly, this courtyard is the school's library and warehouse.

The large brass lock on the gate is eye-catching.

"Do you know how to pick locks?" The hero asked.

"The key is behind the plaque."

"Key ......"

Is it child's play? Treasure trove! A place to hide treasures! It's just a matter of not arranging a security guard, and the key is still within two meters of the door lock, making a joke?!

"The library is the most frequented place for students, and some of them often forget the time when they read books, so the students in charge of guarding simply leave the key for the last students to leave, and they lock the door by themselves.

It is also an old tradition to put the key behind the door plaque. ”

The hero opened his mouth and complained weakly.

"Your father really told you everything, I wonder if there is a female classmate like a white moonlight in his school career?"

"He didn't say it, but I heard my mother tell it."

"Oh? It seems to be a sad story. ”

"That's right, that female classmate didn't choose my father in the end, but succumbed to the family marriage, and is now the wife of the palace master of the Eight Poles Palace."

"Ahem, ahem...... You, you, what do you say? ”

"Remember when I said during the day that my dad and your dad had a few fights?"

"Because of my mother?"

"That's right."

The hero has no idea what to say. He never thought that his father and Su Yanyan's father would have such a bloody relationship.

Well, one is the leader of the Demon Dao, and the other is the leader of the righteous path, and the old lady is mighty!

Wait a minute!

"What does it mean to succumb to family marriage? My mother and my father have a very deep relationship, okay! ”

"Marry a chicken with a chicken, marry a dog with a dog, it's been so many years, what else can you do if it's not deep?"

"Hey! Who's the chicken? Stop playing, go back to sleep. ”

The hero huffed, turned his head and left.

"You...... Xiao Xiongxiong, I was wrong, it was a smooth analogy, and I had no disrespect for my uncle and aunt. Su Yanyan was anxious, and quickly apologized and swore, "If I lie to you, I will ...... I'll never be able to regain my goddess body, okay? Don't be angry, forgive people! ”

The hero turned and walked back, jumped onto the gatehouse, and pulled out a brass key from behind the plaque.

Of course, he knew that Su Yanyan didn't mean to scold his parents.

I finally heard the stupid goddess begging for forgiveness, it's so comfortable!
