After breakfast the next day, Zhang Xu came to Snape's office.

After greeting Snape, Zhang Xu sat down at Snape's desk.

Snape pushed a piece of parchment forward, stared into Zhang Xu's eyes, and said, "I hope you can promise me one thing." ”

"Protect Harry? No problem. Zhang Xu replied.

Snape was slightly startled, then nodded, and then pushed the parchment in front of Zhang Xu.

Zhang Xu secretly complained about Snape's arrogance in his heart, and looked at the parchment.

Written on the parchment are the spell and the unraveling spell of "Shadowless".

"It's a valuable gift." Zhang Xu said in his heart, "It seems that Snape has also paid for Harry." ”

After hearing what Zhang Xu said to Harry last night, Snape had a new understanding of the danger Harry was facing, so he wanted to find a new ally for Harry.

Zhang Xu saw Snape's plan, and anyway, it would be convenient for him to promise Snape to protect Harry, so he naturally agreed happily.

Last year, Zhang Xu found Snape's old Potions textbook through various excuses, and he also taught himself the Divine Edge on it. If you want to use this spell to chop wood during the summer vacation, when the whole family goes out for a picnic.

Zhang Xu saw that Snape's parchment today was gone, and he didn't know how many generations of improved versions it was, and the spell was easier to cast and more powerful.

After Zhang Xu asked Snape a few questions about the Bladeless Spell, he used Transfiguration to conjure a stake, and then cast a Bladeless Shadow on the stake.

The spell hit the stake, and it really hit the wood.

After asking Snape for some more advice, Zhang Xu left the office and walked straight to the room where he needed to practice.

When Zhang Xu felt hungry and came to the cafeteria, he found that lunch time had just ended.

Zhang Xu, who was hungry, had no choice but to come to the kitchen and ask the house-elf for a piece of lamb shank, which was frozen with magic and cut into thin slices.

Then blanch the noodles and put them in a bowl.

Then put the sliced raw lamb, coriander, chopped green onion, chili, minced ginger, salt, pepper, pepper and cabbage into a bowl.

Finally, scoop out a spoonful of piping hot mutton bone broth from the pot and pour it into the bowl, cover the lid and simmer for a while, and a bowl of fragrant mutton noodles is ready.

Don't ask why Hogwarts kitchens have things like chopped green onions, coriander, noodles and pickled cabbage, and there are still sprouts growing in a corner of the kitchen.

After eating the mutton noodles, as soon as Zhang Xu walked out of the kitchen, he heard a few students from the badger academy passing by talking about the attack on Colin last night, and then he received a messenger from someone looking for him to go to the place where the crime happened last night.

As soon as he arrived at the scene of the crime, Zhang Xu saw that a large group of people had gathered there, in addition to the students, there were also Professor McGonagall and two adult wizards who had never seen before.

After Zhang Xu asked the students he knew well, he learned that the two wizards he had never seen were sent by the Ministry of Magic.

The speed of the Ministry of Magic's reaction surprised Zhang Xu a little.

However, looking back, many students in the previous "tea time after school" wrote letters to their families to ask about the secret room, which made the matter of the secret room spread in the school's parent circle. Now that something has happened to a student, and as soon as a group of powerful parents put pressure on them, the Ministry of Magic can't sit still.

The students present were basically members of the "tea time after school", and everyone was recreating the scene of Colin's attack.

A first-year student about Colin's size plays Colin's role and is tossed by a group of older students.

After greeting Professor McGonagall, Zhang Xu took out last night's bunch of grapes and placed them where they fell last night.

"Colin came out last night with this bunch of grapes, and then this bunch of grapes fell here, and Professor McGonagall and I came over last night and found it still there, so we put it away first." Zhang Xu said to the students who were discussing.

Then a group of students began to study the grapes around the bunch.

The wisdom of the masses is infinite, and from the fact that this bunch of grapes was basically unharmed except for falling to the ground and breaking a little and Zhang Xu stealing two of them, everyone eliminated a lot of powerful magic, and limited the magic to magic such as the sound of a mandrake and the gaze of the legendary Medusa.

After handing over the bunch of grapes that had completed his mission to Harry, Zhang Xu began to study with everyone what Colin had seen last night.

Soon, everyone came to the same conclusion as Zhang Xu last night, Colin only picked up the camera after standing on the stairs and seeing the shadow cast on the other side of the corner of the corridor opposite.

So, under the astonished gaze of the two Ministry of Magic staff, the students closed all the windows around the hallway and staircase, and lit the lamps to simulate the environment of last night.

The first thing to be excluded was the magic item, because the shadow of the person holding the magic item obviously did not frighten people, so Colin was surprised to pick up the camera and take a picture.

Then the only answer left is a monster who can do magic.

After using transfiguration to make entities according to the illustrations in the book, everyone experimented with their shadows according to the original selection of a few magical monsters.

As a result, their shadows are quite scary.

The investigation went on at this point, and after a while of talking, everyone dispersed, leaving only Professor McGonagall and two stunned Ministry staff members.

Next, Zhang Xu walked out of the castle by himself and walked towards the greenhouse.

On the way, he saw the three of Harry walking towards Hagrid's hut, presumably to comfort Hagrid from the old era.

Now Hogwarts is in a big place, and in addition to growing herbs, the new greenhouse has opened two greenhouses dedicated to growing vegetables. And these greenhouses are all magically blessed, no matter how cold and snowy it is outside, the indoor temperature is above 20 degrees Celsius.

Zhang Xu found that there were not many coriander in the kitchen just now, and he had to plant a batch now, otherwise there would be no coriander to eat when he came back from the Christmas holiday.

Think about being able to drink a bowl of hot yam mutton soup with coriander floating on a cold winter night, and the whole person will warm up.

Zhang Xu broke the shell of the coriander seeds, put them in a basin, and then added water to the pot. After two days, the soaked seeds can be placed in a wet burlap to germinate.

Walking out of the greenhouse, Zhang Xu saw Professor McGonagall walking towards Hagrid's hut with the two Ministry of Magic staff members.

Zhang Xu didn't care about them, and when he saw that the time was just for dinner, he went back to the cafeteria for dinner.

As a result, Zhang Xu didn't look for trouble, but things came to him.

After dinner, Zhang Xu played table tennis with Justin Finchrie of the Badger House on the newly built table tennis table at the edge of the Ice and Snow Waterfront Garden.

Justin's parents were also table tennis enthusiasts, and Justin Finchly Finchrie also played ball since he was a child, and among the students in his grade, no one dared to call him third.

When Zhang Xu and Justin finished a game, Harry came over and said that he needed Zhang Xu's help.
