Thick layers of snow covered the snow-capped mountains to the north, the rooftops of every Hogmodri building, and the clearing around the village. The thick clouds in the sky have disappeared, and the setting sun spreads over the land, giving you a great view of the original orange cat.

In a large clearing near Hogwarts, a huge exhibition tent has appeared. At this moment, people are constantly coming and going at the door of the tent, either carrying goods or carrying stacks of posters to the designated place to paste.

Not far away, the residents of Hogsmeade and the Ministry of Magic staff gathered after work, sometimes pointing at the exhibition tent and the stage being built in front of the tent, sometimes discussing the various posters on the wall in a curious and slightly excited tone.

In the expanded exhibition tent, there are several areas of different sizes for different types of products, and in these areas, they are divided into different types of stalls. In the deepest part of the tent is the office area for the staff.

In a cubicle in the office area, Zhang Xu was sitting behind a desk and writing hard. After a long time, he put down the pen in his hand, picked up the manuscript paper on the table, checked it, and then stretched out his hand to the side. At this time, a staff member from the embassy who came to support handed a programmable calculator into Zhang Xu's hand, and then Zhang Xu began to input the program on the manuscript paper into the calculator.

There is a very serious problem when people come to the UK to do business, and that is the currency conversion problem here in the British wizarding world. The currencies here are the Galleons in gold, the Sicos in silver, and the Nat in bronze. And 1 galleon = 17 sican = 493 nat, 1 cico = 29 nat, which can make the heart of businessmen who are accustomed to decimal fillet points hang.

In the past, everyone was in the wholesale business, and everyone just erased a fraction for the convenience of calculation. But now there is also retail, so it is not easy to wipe the odds.

Therefore, the easiest way for everyone to think of is to urgently buy a batch of programmable calculators back, and then Zhang Xu writes the program to calculate Garon, Sike and Nat, and finally enters the program into the calculator and sends it to the merchants for use. After a long while, Zhang Xu finished inputting the calculation program, and randomly found a set of numbers to test it, and there was an error.

When the sunset outside was hidden behind the mountains, and the stars appeared in the night, he finally tossed the calculation program. I haven't used the BASIC language for too long, and it turned out to be a rollover today.

After writing the latest version of the program on paper and handing it to the staff, Zhang Xu went to the canteen on the side and asked for a bowl of noodles, and the follow-up work was completed by the relevant staff.

After his Muggle studies class this afternoon, he rushed over to toss the calculator without dinner, but fortunately he had eaten enough roast lamb in the dungeon before, otherwise he would be hungry enough now.

After eating noodles, Zhang Xu came to an office again, and Zhao Lao was also sitting behind the desk, but he was holding a pen and thinking about something.

Seeing Zhang Xu come in, Zhao Lao put down the pen in his hand, rubbed his brows and said, "Have you eaten?" ”

Zhang Xu nodded and replied, "I'm done, I've eaten." Is there any other task for me to wait? ”

"We'll be gone for a while." Zhao Lao said while pouring himself tea, "But someone from Scrimgeour brought a message over there, asking you to go there if you have time." ”

"Then I'll be free later." Zhang Xu found a chair and sat down, "I saw you having such a headache just now, what national affairs are you thinking about?" ”

"Write a report." Elder Zhao put down the empty teacup, "I told them that Brother Xiangyu once said, 'Some laws of material production are also applicable to spiritual production. If we go too far, mental production will be damaged, and even more so. But they just urged me to report. ”

"But what he said next was, 'There are some drafts to be rushed.'" Zhang Xu said embarrassedly, "You can still quote scriptures, don't you often brag that you don't make drafts when you take the palace exam, and your pen is like a dragon, and you can achieve it overnight?" ”

"That's why Shuping became the champion." A certain Qing Jinshi said.

After learning that he had no task tonight, Zhang Xu stopped bothering the big guy, and after bragging for a while, he said goodbye and left.

Thinking about it, after a few days of running-in, the cooperation between the wizards between the two countries has been on the right track, and there is no longer a need for him to communicate and coordinate in the center, and for a while Zhang was actually idle.

And Mr. Delacour, who came to England on behalf of the French Ministry of Magic to make a fortune, will return to France today after talking about business, so Fleur decided to go home with her father by the way, and after running back to Europe for so long, it is impossible to say that he does not go home.

Zhang Xu, who had nothing to do, didn't want to go to Hogwarts to change the students' homework so early, so he came to the stall of his own industry to help. It's just that when he was helping to assemble the shelves, he found that his family looked at him strangely. Zhang Xu suddenly remembered that someone told him at noon today that something was going to happen tonight, and he couldn't help but be alert.

It was half past ten, and the day's work was over, and Zhang Xu followed his family back to the place where he settled in Hogsmeade for supper.

The original Lestrange family property here was later obtained by Zhang through some means, and then he used this property to replace the Zhangjia building on the north side with Neville's relatives. This time, a large group of people came to the house, so Zhang Xu contacted his relatives through Neville and rented this small building for the family to settle in.

When the family returned to the small building, Zhang Xu found that there was no supper, but the family sat neatly in the living room, and then looked at their own house that was boiling water and preparing to make tea.

Zhang Xu, who didn't understand the situation, decided not to change and entered the obedient cub mode on the day of the parent-teacher conference.

But the one who should come still has to come, and the first to speak is Zhang Xu's grandfather.

Zhang Feng took a sip of the Tieguanyin handed over by Zhang Xu, moistened his throat and said, "Xiao Yiyi, I have something to ask you." ”

Zhang Xu was shocked, his grandfather's tone was the same as when he came back to talk to him after the parent-teacher meeting before.

"What's the matter, Grandpa?" The well-behaved Zhang Xiaomaruko asked.

"What's the matter with those two little Indian girls?" Zhang Feng asked, "People's mothers have come to the door, I heard that you have prepared a large amount of pocket money for others?" ”

When Zhang Xu heard this, his face immediately changed.
