The willows on the moon, the spring is getting stronger.

----

It's the end of spring and the beginning of summer again.

Eight-year-old He Yingzhe grew like a willow tree, and he lost the baby fat of his infancy, and had a bit of the brightness and heartiness of his youth.

He Wanyi has also lost a lot of weight, but her face is still round, adding a bit of honesty and cuteness.

Both of them have to go to the academy every day to study and attend classes.

He Yingzhe went to the Guozijian Juvenile Academy, and the people who could study here were all children of his age, and regardless of their status, rich or poor, as long as they were willing to study hard and were qualified, they were all able to enter the academy.

The daily classes in the college are very busy, and they have to start reciting poems and articles before dawn in the morning, practice calligraphy, and learn mathematics, chemistry, agricultural flow, etc.

In addition, Danqing, Go, riding and archery and other subjects are also within their scope of study.

It can be said that He Yingzhe opened his eyes in the morning and returned to sleep at night, and his daily course schedule was very tight, and there were a lot of things to learn.

Because the Guozijian Juvenile Academy has a heavier workload than other academies, many people have to transfer to other academies to study, even if they first enter the academy.

But it is precisely because the Guozijian Juvenile Academy is so strict that the people who come out of the academy from then on are all dragons and phoenixes among people, very outstanding, and have also become the "white moonlight" in the hearts of too many people.

Many people are proud to be able to study at the Guozijian Children's Academy, and many parents are doing everything possible to send their children to school.

It's a pity that the head of the Guozijian Juvenile Academy has a very strange temperament, he doesn't open the back door to anyone, and his status is respectful, even the emperor has to give seven points of face, and everyone doesn't dare to provoke at will, so they have to come in a proper manner.

Faced with such a situation, An Guogong thinks that he is very satisfied, and what he likes to do every day after dinner is to walk slowly in the academy with his hands behind his back, watching the birds and flowers in the academy, the trees are lush, and listening to the sound of books in the academy......

"Boom!"

The sudden sound startled An Guogong, who was brushing his beard, almost pulled off a handful of beards, and after distinguishing where the sound was, he walked in three steps and two steps.

The house that made the noise was now emitting puffs of smoke, so that the students in the room had to flee, and each of them was choked and coughed.

"Something's wrong!" An Guogong looked at several of the students whose faces were blackened and asked anxiously.

The most smoked students barely managed to stabilize their breath after a cough, and replied truthfully, "The master told him how to prepare gunpowder, but He Yingzhe said that the ratio was not right, and there was more charcoal, so the master readjusted, and the two argued......

"So the two of them had to try it out in their own way, and it turned out like this."

As the words landed, two more figures walked out of the room.

It was also smoked black, and there were even some traces of burning on the clothes.

And the two of them were dejected at this time, like frosted eggplants, but after glancing at each other, they raised their eyebrows.

"Master, can you prove that there is a problem with your gunpowder ratio now?" He Yingzhe said.

But the master also pulled the corners of his mouth, "Don't be proud, your ratio is not very proper, the amount of charcoal is insufficient, it is difficult to produce the power it should have, and you can only produce such thick smoke."

"But the one made by the master didn't explode at all, and the student was barely able to do that, doesn't that mean ......?"

"It means that both of you have your heads caught in the door today!" An Guogong interrupted the argument between the two of them, blew his beard and glared and shouted, "Discussion is discussion, is it necessary to give it a try?" Still in the academy!"

"Gunpowder is already very powerful, and this time you two are lucky to have not made any mistakes, if something goes wrong, how can you get it?"

"As a master, you don't care about the safety of your students, and you deserve a heavy punishment! At this time, you will go and stand outside for an hour, and write a thousand-word letter of repentance!"

Seeing that An Guogong was angry, the master didn't dare to argue, so he only shrunk his neck and responded, "Yes."

"And you!" After An Guogong finished scolding his master, he turned to He Yingzhe, "If you make firearms without permission regardless of the danger, you should also be punished together, and you will be punished for standing with your master for an hour and writing a 500-word letter of repentance!"

"Yes." He Yingzhe was also well-behaved at this time, and even bowed down, and said after a while, "The mountain chief just said that students should not make firearms without authorization, so who should students tell when they make firearms next time?"

"No more firearms without my permission!" An Guogong shouted.

"Yes." He Yingzhe bowed down, and then asked, "Then when will the mountain chief allow such things as firearms?" The chief of the mountain told me that the students also have a number in their hearts, and they can prepare in advance in the future."

An Guogong, "......"

Is this a firearm a must-have?

Whether it is He Yanxiu or Su Yujin, they are all reasonable people in Su Ri, how could they give birth to such a shaft son?

The corners of An Guogong's mouth twitched for a long time, and he almost squeezed out a sentence from between his teeth, "Go out and stand!"

"Yes." He Yingzhe bowed down again, and then walked out very obediently, and arrived at the designated position to accept the punishment.

It's just that the two of them stood together, and after snorting coldly, they turned their faces away, as if no one was convinced.

Seeing this, An Guogong became even more angry in his heart, glanced at the other masters and students who were watching the excitement there, and shouted angrily, "It's all gone!"

The master and the students did not dare to stay any longer, and after they dispersed, they began to busy.

And An Guogong left with his hands behind his back and huffing.

After returning to the house and drinking a whole pot of herbal tea, An Guogong felt that the anger in his heart could not be suppressed, so he simply got up, and went to the household to find He Yanxiu with a carriage and horse.

He Yanxiu was very surprised by An Guogong's arrival, "What kind of wind blew An Guogong here?"

"The wind that blew up when your son was making firearms." An Guogong didn't have a good airway.

And He Yanxiu was stunned for a moment after hearing An Guogong's words, and then his face was full of joy, "What does An Guogong mean that the firearm made by Zhe'er can be exploded?"

"That's really rare, Zhe'er looked through some information books before, tried for a long time, but after all, he didn't succeed, I never thought that now in the academy the experiment was successful, that is really a happy thing."

"An Guogong praises falsely, Zhe'er is just a casual tinkering with the child's family, and he is not too talented in this regard, so he really can't stand An Guogong's praise......
