After leaving the café by the River Thames, Zhang Xu and Scarlet bought a new mobile phone and returned to their London home.

The mobile phone that Zhang Xu left for Dobby in Hogsmeade Villa before was accidentally taken to Hogwarts Castle by Dobby, and as a result, many components in the mobile phone were burned, so the phone was turned off when Harry called Dobby the next day.

Zhang Xu has been wondering, since Hogwarts' defensive magic can interfere with the use of electronic products, can it interfere with the operation of magic through strong magnetic fields, electromagnetic pulse bombs, etc.?

For example, if you detonate an EMP bomb next to Hogwarts, can it interfere with, or even undermine Hogwarts' protection?

It's a pity that he can only think about this kind of thought for now.

In recent years, the EMP bomb was still a top-secret weapon that had been kept secret by the major powers, and it was impossible for him to get one and take it to Hogwarts to blow up. Even when he traveled back in his previous life, the models, physical photos, and data of such weapons were still not announced.

As for the weapons that can produce the same effect, there are only nuclear weapons, and this thing is even more difficult to try.

This time, Zhang Xu and Scarlet came to London to find a suite in a five-star hotel as a foothold, although it made him a little painful when he paid, but it was better to be quiet and no one bothered.

In the early hours of the morning, Scarlet walked into Zhang Xu's room with a glass of cocoa milk.

At this time, Zhang Xu was sitting in front of the desk, writing something into his laptop.

Scarlet put the cocoa milk next to his laptop and walked behind Zhang Xu.

Zhang Xu poured the milk from the cup in one go, and then crackled on the keyboard with only his right hand.

"Staying up late tonight?" Scarlett asked.

"Yes, there is no way, there are too many other things recently, and it is inconvenient to input with one hand, so I can only stay up late and work overtime." Zhang Xu replied.

"You've only slept for less than four hours in the past two days, haven't you?" Scarlet asked again.

"It's okay, it's not a big deal." Zhang Xu replied.

"You save it first." Scarlett said.

"What's wrong?" Zhang Xu asked as he saved the file.

"I promised Fleur to supervise you and ensure your rest." Scarlett said.

"It's okay, I'll go to sleep later, you go back to your room and sleep first." Zhang Xu waved his hand and said.

"I'll go back, who's going to carry you to bed?" Scarlet stood behind Zhang Xu and said.

"What?"

"Faint!"

With such a simple spell, Scarlet could already cast a spell without a wand.

After sighing, Scarlet cast a levitation spell on the fainted Zhang Xu and threw him onto the bed.

After covering Zhang Xu with the quilt, Scarlet turned off the light in the room, then closed the door and returned to his room.

The next day, under the dual effect of the Living Hell Decoction and the Sleeping Spell, Zhang Xu slept until noon before getting up.

Not long after getting up, Zhang Xu received a call from Furong, because of the irregular sleep in the recent period, Zhang Xu was nagged by Furong on the phone for more than half an hour.

Zhang Xu promised on the phone that he would have a good rest today until he went to bed at night and would no longer touch the matter of work.

"Let's go out for a walk."

After eating a simple lunch, Zhang Xu said to Scarlet, who was helping him with the medicine on his left hand.

Scarlet nodded, went back to the room and changed into an ordinary dress, and then walked out of the hotel with Zhang Xu.

Not far from the hotel gate, Zhang Xu met two old men asking for directions.

"Excuse me, little comrade, how should I get to the Greenwich Observatory?"

Looking at the two old men in front of him who asked for directions in Chinese, Zhang Xu was a little in a trance.

"Old comrade, we're going there too, or let's go together." Zhang Xu replied.

Originally, Zhang Xu and Scarlett didn't have any plan in the afternoon, they just wanted to walk around.

So Zhang Xu simply decided to act with the two old men.

On the way, Zhang Xu chatted with the two old men.

"So Xiao Zhang, you've been studying in the UK for four years?" The old man asked.

"yes, I came here when I was eleven years old. However, I have always been studying in the north, so I have not had much opportunity to walk around London. Zhang Xu replied.

"Seeing that you have found such a beautiful girlfriend in the UK, it seems that you are doing well here." The old man quipped.

"Grandpa Li, don't laugh at me." Zhang Xu said embarrassedly.

"Listen to the accent, you're from the south, right?" Grandpa Li asked.

"Yes, I'm from Yongcheng." Zhang Xu replied.

"Oh, I've been to Yongcheng. If I hadn't been injured and stayed there to recuperate when Shenyang was liberated, I would have fought all the way to your house with my comrades-in-arms from Siye. Many of my old comrades-in-arms have settled there after they have been discharged from the army, and when I went to see them last month, I had a supper at the Zhongshan Road Night Market. Grandpa Li said with a smile.

Zhang Xu also smiled.

At the same time, he was also thinking in his heart, if you were not injured, you would come all the way to Yongcheng and be discharged from the army, and then assigned to work in a construction engineering company, and then your daughter would be abducted by the son of your colleague in the opposite office, and in two years you would have a smart, lively and lovely grandson.

This is the first time Zhang Xu has seen someone who is related to his previous life since he came to this world.

In this regard, Zhang Xu didn't bother to think about the principle.

He has lived in the same city all his life as his previous life, and during the summer vacation of the fifth grade, he pedaled his bicycle to the place where he lived in his previous life.

Along the way, Zhang Xu was thinking, what if he saw someone like him in his previous life, if the "self" in this world was a girl, should the fat water not flow into the fields of outsiders.

At that time, he remembered a book he had read before he crossed over, and when the protagonist "went home" after crossing, he found that "himself" had become a sister, and then that "sister" became the roommate of the protagonist's girlfriend, and finally the protagonist received "himself" into the harem and lived a "Japanese" life every day......

When he came to the familiar and unfamiliar street, he saw the same lighting stadium and the shop next to the stadium as he had in his previous life, and many conspicuous trees were also there, but the loquat tree that his grandfather planted in front of his house after moving here in his previous life was not here.

After some inquiry, he learned that his "grandfather" had not moved here at all.

After that time, Zhang Xu gave up his plan to continue to inquire about this matter.

Throughout the afternoon, Zhang Xu enthusiastically took the two old men around the Greenwich Observatory and began to translate for them.

In the end, he insisted on inviting the two old men to an authentic British meal.

As night fell, Zhang Xu and Scarlet returned to the hotel.

It's rare to stop thinking about things at work, and today Zhang Xu played completely relaxed for a long time.

"You're having a great day." Scarlet said to Zhang Xu.

Zhang Xu, who was lying paralyzed on the sofa, nodded and said, "I didn't expect to meet an old man who has a relationship in London, thousands of miles away, and I was inevitably a little excited." ”

During the afternoon chat, Zhang Xu said the names of a few old cadres from Siye whom he knew in the compound, and it turned out that "grandfather" was once one of the soldiers. So Zhang Xu said that he was a related person, and Scarlet didn't think of going anywhere else.

"You don't seem to like talking much lately?" Zhang Xu asked Scarlett.

"Nothing." Scarlett said.

"Guilty about the injury to my left hand?" Zhang Xu asked again.

Scarlett didn't speak, and turned his head out the window.

"What's there to feel guilty about." Zhang Xu stood up and sat down next to Scarlet.

"I told you to go up at the time." Scarlet said with his head down.

"At that time, in the face of such a fast zombie, someone must have been in front. At that time, I was ready to take a bite. Zhang Xu said, "Who knew that the poison of that hairy zombie was so special, it was the content of the third year of high school, and I haven't learned it yet." The shelf life of special drugs is too short, so there is no ready-made one in China, and it can only be used now. After a few days, the medicine will be ready and it will be fine when it arrives. ”

"However, you can dodge it at that time......" Scarlett's words were interrupted by Zhang Xu.

"It's nothing, but, you were behind me at the time." Zhang Xu touched her head and said, "According to its height, it is right on your forehead." If you are bitten on the forehead by it, do you want to play Bao Qingtian with a black face? Besides, I won't feel sorry if you break your appearance. ”
