With the basic design principles in mind, Zhang Xuan began to work with his left hand. However, it is a difficult process to move from theory to practice.

This automatic shield is like a car's airbag, which automatically pops when it is struck by magic at a certain speed, but it is much larger than an airbag.

Zhang Xuan needs to find a magic detection device first, a sonar speed measurement device, then a trigger alarm device, and finally a magic storage device and a defense device.

A set of devices should not be too big, they should be easy to carry, and there must be a powerful magic storage device, otherwise the magic power will be insufficient, and the protective shield will be broken all at once, so it is better to take a shield.

But don't be in a hurry, you can't eat hot tofu in a hurry! Zhang Xuan wrote down everything and began to study them one by one.

After the Quidditch match, everyone's life gradually became tense.

Because the final exams are approaching, Zhang Xuan has also gone to Hagrid to visit Nesario less often.

"Zhang Xuan, do you know?" While Harry was doing his homework, he whispered to Zhang Xuandao:

"Yesterday I saw Snape arguing with Professor Quirrell outside the hallway on the third floor, and Snape's foot was injured!"

"Looks like Snape is ready to steal the Philosopher's Stone, but unfortunately he can't handle the three-headed dog!" Ron smiled:

"Maybe we can go to Professor Quirrell, he should be our ally too!"

"We should sit on the sidelines until the truth is revealed!" Hermione said, "After all, the Philosopher's Stone of Immortality is something that everyone wants to keep for themselves!" ”

I didn't expect Hermione to be so sensible, Zhang Xuan also nodded and said, "Hermione is right!" Now that Snape is injured, we can rest assured for a while and concentrate on preparing for the exam! ”

"That's a good point!" Ron nodded and said, "I really don't know, it turns out that there will be so many homework in the exam season, the history of witchcraft in the history of magic, and the grand view of leaves in botany, it's really annoying!" ”

"It's alright!" Hermione said, "I heard that there will be a test for the Werewolf Administration Act of 1637 and the Beginning and End of the Elven Rebellion, have you read it?" ”

"Wouldn't it? Do you still want to take these? Ron and Harry looked at each other, and their heads suddenly felt dizzy.

Zhang Xuan smiled: "I don't think I should take the test, because this is the content that will only be learned in the second grade!" ”

Harry and Ron were relieved, and Hermione whispered, "Zhang Xuan, don't you really need to take the test?" ”

Zhang Xuan also said in a low voice: "No need to take the test, by the way, your hair is very fragrant!" ”

Hermione suddenly blushed and looked down at the book, Zhang Xuanxin said, this girl developed early, or is it true, she knows that she likes people at such a young age, and most boys of the same age are just playing.

"Zhang Xuan! Are you done with your Potions homework? I forgot to write it yesterday! Terry said with a bitter face.

These days, the amount of homework assigned by several professors has also increased greatly, and many of them are working all night to write homework.

After all, students in the wizarding world go to school, just look at their grades, and if your grades are not good, you can only repeat a grade, after all, this is not compulsory education.

"This is here, remember to change it a little!" Zhang Xuan smiled,

"You know, you can rest assured!" Terry happily took his homework and went back.

And Zhang Xuan's life is still peaceful, except for more homework, he doesn't spend more time reviewing his homework, which seems to be light.

The final exams are coming soon, and the first exams are the history of magic in the textual class, ancient magic texts, astronomy classes and divination classes, and the exams are dizzying.

Zhang Xuan finished the exam very smoothly, and then handed in the paper in advance, and then the others slowly wrote it.

The top students answered each other after submitting the papers in advance, and Zhang Xuan's answers were completely correct.

"Zhang Xuan, you are really amazing!" Bonaparte exclaimed, Bonaparte was a Hufflepuff student, and a powerful scholar,

"You're getting a perfect score again this time!" Hermione said, "Then we'll only be able to score one more point in the magic application exam!" ”

Xueba has a circle of scholars, and scumbags have a circle of scholars, and when everyone comes out after the exam, everyone communicates with each other, and only a few people sit firmly in Diaoyutai.

"I don't think it's too difficult this time!" Harry said, "It should be able to pass!" ”

Ron said with a bitter face: "I would have read more books if I knew it, I feel like I have forgotten a lot!" ”

"I told you to read more books earlier, but if you don't read them, what can I do now!" Hermione said angrily, "Now we have to leave it to our fate, and see what you have left to the rest of your magic application exam results!" ”

"Don't worry too much, you'll definitely pass!" Zhang Xuan said with a smile, although Harry and Ron are playful, their grades are still average, and it is not a problem to pass the exam.

At the beginning of the second day's magic application exam, Mr. Flivik from the Charms class said, "Today's exam, let's let a pineapple dance around the classroom to pass the exam!" ”

This pineapple dances and spins in circles. First of all, the levitation spell is examined, and then the dancing spell, the difficulty is the release of the magic of the levitation spell, if the levitation spell is not mana, but it can't support the pineapple to turn around the classroom.

Fortunately, those present knew yesterday that the exams were all meditative nights, and the magic was abundant, and even the worst Neville stumbled through the magic.

And Professor McGonagall's Transfiguration exam, which is a little more difficult, "Turn the mouse into a cup, the more complete and beautiful, the higher the score!" Professor McGonagall said.

After such a long period of study, everyone is very proficient in turning dead things into dead things, but it is the first time that living things have turned into dead things.

"Sixty-five points!" Professor McGonagall scored them one by one, some of them had furry quilts, some had a little tail leaking out of their cups, and some had some beards.

"Seventy points!"

"Sixty points!"

"Seventy-five points!"

Professor McGonagall commented one by one, and when Zhang Xuan arrived, Zhang Xuan's wand turned into a transparent coffee cup, which was the first time that any student turned a mouse into a perfectly transparent cup.

"Yes, finally someone hasn't turned into a ceramic cup, and I can't tell it's a mouse at all!" Professor McGonagall tapped her hand as she spoke, and the glass made a crisp "dingding" sound.

"One hundred!"

Then Professor McGonagall went to see the others.

"Hermione, ninety!"

"Harry, ninety-five!"

"Ron, seventy points!"

"Malfoy, ninety-five points!"

Hermione was a little angry, she was not as good as Zhang Xuan, but even Harry and Malfoy were not compared, which really hurt her self-esteem.

In a few moments, Professor McGonagall was giving everyone a grade.

"Whew, it's finally over, it's been in vain that I've been practicing for half the night," Ron laughed.

But Malfoy said: "What is there to be proud of, the next exam, but potions, when the time comes, I want to make you look good!" ”
