In the last class on Friday afternoon, in the Muggle Studies classroom, seventh-grade students, who had just finished learning "the meaning of commodities and the commodity economy," were discussing a question posed by Zhang Xu.

"A argues that the amount of value of a commodity is determined by socially necessary labour time, and therefore individual labour time has no practical significance to the producer of the commodity.

B disagrees, arguing that socially necessary labour time is invisible and intangible, and therefore only individual labour time has practical meaning for commodity producers.

Do you think they're right? Why? ”

Until the end of class, the students did not reach an agreement on this issue, so Zhang Xu took this question as an after-class assignment and asked everyone to go back and write a paper to explain their ideas.

After assigning another paper on "How to Look at Money", Zhang Xu announced the end of class at the same time as the bell rang.

Fortunately, Zhang Xu has always had no requirements for the number of words and the length of the parchment paper, as long as he fully expounds his own views, so the pressure on the students of the two papers is not great.

After class, Penelope, who was in the Eagle Academy with Zhang Xu, went to the podium to find Zhang Xu.

"We're going to have dinner at the Screaming Shack tomorrow night." Penelope said to Zhang Xu.

"Is it okay for you to tell the professor that you were going to break the school rules?" Zhang Xu said with a black line.

"Tomorrow's Quidditch match is our Ravenclaw House vs. Gryffindor House, and everyone has agreed on who loses and who will be treated." Penelope ignored Zhang Xu's question, and seemed sure that Zhang Xu would not deduct their points for it.

"I'm against this, let them go to the kitchen and make trouble." Zhang Xu said to Penelope, "Although the Dementors promised not to enter the Hogwarts campus, they never said they would not go to the Screaming Shack to attend your dinner. ”

Seeing Zhang Xu's opposition, Penelope had no choice but to give up. The main purpose of their persuasion of Zhang Xu to participate was to let Zhang Xu drive away the Dementors, and if Zhang Xu didn't go, they wouldn't be able to go.

For a group of students who are used to making trouble, this year's ban on outdoor activities has made them uncomfortable.

The next day, Saturday, was a cool, sunny day, perfect for Quidditch.

Zhang Xu arrived at the Quidditch pitch early in the morning and sat on the highest stand where he had been during the last match.

Now he comes to the stands every time a Quidditch match comes, mainly in case the Dementors come back, he will take care of it. So he won't be able to play this year.

Dumbledore sent a message to Zhang Xu early in the morning, if there were any Dementors coming to the campus in the future, let Zhang Xu kill them, and he would be responsible.

At eleven o'clock, the Quidditch match officially began.

Today's game was extremely intense, and the two teams that were fully equipped with new brooms, after each experiencing a run-in of a game, played the performance of their respective brooms almost perfectly in this game.

For a moment, the stadium was full of blue and red shadows flying.

The players of both teams kept sprinting, making emergency stops, packing, and diving, and the students in the audience were dazzled.

The scores of both teams rise in alternation.

The most intense battle on the field was the confrontation between the two Seekers.

Whenever Harry Potter saw the Golden Snitch, Zhang Qiu stepped forward to harass him.

Harry suddenly noticed a golden flash appear close to the ground, and immediately turned the broom and rushed in that direction.

In order to get rid of Zhang Qiu's interception, Harry flew the speed of the broom to the maximum.

As a result, a blue figure suddenly rushed in front of Harry, blocking his path.

By the time Harry reacted, the Golden Snitch was gone.

After a few more battles between the two, Harry Potter discovered that Zhang Qiu's broomstick could fly five or five times with his own broomstick.

Zhang Xu, who was sitting in the stands, was eating fried chestnuts with sugar while paying attention to the contest between his aunt and Harry Potter.

The Dongfeng 31 used by Harry Potter today is the fastest broom sold in the Weasleys' shop, and it can be said that this is the fastest broom that can be bought in the British market.

The Lion Courtyard team has the Weasley family as the backing, but it can't stop the Eagle House team from having Zhang Xu as the backing.

Zhang Qiu's flying broomstick was specially adjusted by Zhang Xu to the manufacturer during the summer vacation, and in the name of senior user technical guidance, the manufacturer made special adjustments on the basis of Julang No. 1.

Zhang Qiu's broomstick optimizes maneuverability and maneuverability while slightly sacrificing maximum speed. Then it added a short-term afterburner sprint, which can burst out in a matter of seconds with a speed no less than that of the Dongfeng 31 used by Harry Potter.

The strategy of the Eagles team today is to send Zhang Qiu to interfere with Harry Potter with all his might, and create time for the team to open the score as much as possible. If the score can't be drawn, then keep interfering with Harry Potter's activities and waiting for an opportunity to catch the Golden Snitch.

This year's Quidditch tournament has a big advantage in the Eagle House, and after winning the first game against the Badger House, if it wins again, this year's Quidditch champion will not be able to run.

As for the snake courtyard, they were all crying and fainting in the bathroom.

Now the hope of the Badger House to win the championship is the defeat of the Eagle House, and then brush enough points on the Snake House.

And no matter who loses this game, the losing side must also take the snake courtyard to brush up enough points.

While eating amber almonds, Zhang Xu calculated the chances of his own college winning the championship this year, and found that his own college had a great advantage.

As for Oliver Wood, who wants to lift the championship trophy before graduating from Hogwarts, Zhang Xu can only say sorry to him, you are not Roberto Baggio who missed a penalty half a year later, so Zhang Xu will not feel sorry for him.

While the attention of the students and professors in the audience was focused on the air, Zhang Xu noticed that three sneaky figures appeared on the top of a nearby barely empty stand.

At this time, the battle between the Seekers entered a white-hot stage.

Both teams played tenaciously on the pitch, and the score kept alternating and couldn't pull away, so both sides pinned their hopes of winning the game on their own seekers.

Now Zhang Qiu has also changed his tactics and took the initiative to attack after discovering the Golden Snitch, while Harry Potter has changed roles and interfered with Zhang Qiu's actions with all his might.

For a moment, the two Seekers entered mutual damage mode, constantly causing trouble for each other.

Just then, Harry's eyes were looking around for the Golden Snitch and he saw a magical scene on top of a certain stand.

Three Dementors, three tall, turbaned black Dementors, were being pinned to the ground with paws and paws by three equally tall, bear-like Patronus, but with round faces and ears.

Today's business trip plus overtime, I don't know if I can watch two shifts.
