On the lively Christmas, Xin Sheng and the other two put down everything they had and planned to enjoy a few days of vacation with peace of mind.

The six-year retreat made the three of them gradually get used to the slow-paced life in this world.

Xin Sheng never expected that as outsiders, they would welcome an unexpected visitor on Christmas.

"Um?"

Just as he sat down and was about to have a big meal, Xin Sheng suddenly felt a request for access from his magic fireplace.

Natiya and Xiri also looked at the fireplace curiously: "Who?"

Xin Sheng shook his head: "I don't know, but the other party is quite polite and does not force his way. He should have no malice, but just in case..."

Through Xin Sheng's research on the Sei-Free Expansion Curse, Natiya and Xili successively built their own portable spaces and could use weapons to arm themselves at any time.

Without knowing the identity of the visitor, the two did not show obvious hostility, but took out their wands and hid them in their sleeves, ready to deal with emergencies.

"Swish!"

After Xin Sheng opened the permission, the green flame formed by Floor powder appeared in the fireplace.

A tall old man with gray hair and long beard walked out of the fireplace with a smile.

Seeing the hearty meal platter on the dining table, the old man smiled self-deprecatingly: "Sorry, it seems that I was at the wrong time."

Natiya and Xiri have read a lot of magic books in the past six months, and the portrait of the old man in front of him often appears in various books.

Natiya opened her eyes slightly and almost exclaimed subconsciously.

Curiosity flashed in Cili's eyes, and the emerald-colored eyes looked back and forth on the old man.

Xin Sheng showed a look of surprise just right: "Professor Albus Dumbledore, the strongest white wizard of this century, how could you..."

“Haha~”

Dumbledore waved his hand with a smile: "Don't be so polite, I'm just a bad old man who has lived a long time. Just call my name directly."

Xin Sheng couldn't help but complain in his heart: 'It's weird.'

Considering that Dumbledore likes to use soul-sucking thoughts to peek at others, Xin Sheng was particularly alert and tried to empty his brain with the method of meditation.

‘It seems that the research on brain closure must be put on the agenda… Why did Dumbledore find me, the unknown?’

Xin Sheng has only been to Glastonbury once in the past six months. He occasionally goes around the surrounding towns and asks himself that he has never made eye-catching actions.

Xiri and Natiya guard their experimental fields all day long, and they spend less time out than Xin Sheng.

Dumbledore was politely guided to take his seat. The strongest white wizard, who was privately called Old Honey by many, maintained a kind smile on his face, and half-spoken and half-spoken at Xin Sheng's polite invitation to enjoy this sumptuous dinner with the three of them.

After dinner, Natiya and Xiri consciously entered the kitchen and began to clean up the plates, leaving space for Xin Sheng and Dumbledore.

Xin Sheng brewed a cup of black tea for himself and Dumbledore respectively. Watching him throwing sugar cubes into the cup, Xin Sheng's eyebrows twitched a little.

‘It is worthy of being a sugar-loving old honey…’

After having enough tea and food, Dumbledore finally slowly expressed his purpose.

"Mr. Xin Sheng, as President Hogwarts, I formally invite you to serve as the professor of the Dark Magic Defense Class for Hogwarts next year."

"……ha?"

Xin Sheng looked at Dumbledore with amazement and said, "Please wait, Professor Dumbledore, you said... let me be the subject professor of Hogwarts?"

"Yes, you heard it right."

Xin Sheng's mind was full of question marks: "Why? With your network of contacts, we should have found out about our abnormalities long ago. Why did you invite me to Hogwarts as a professor of black magic defense classes that will be changed every year?"

Xin Sheng and the other two claimed to be from the United States, but this was just a lie after all.

As the greatest white wizard of this century, Dumbledore has such a wide connection in the international magic world.

If he really wants to investigate the origin of a person, half a year will be enough to turn the whereabouts of Xin Sheng and the other two.

Xin Sheng can't like Dumbledore or hate him.

Many of Dumbledore's decisions were good, but his unscrupulous approach to achieve his goals made it difficult for many of his own people to accept.

Xin Sheng had no intention of contacting Dumbledore and Hogwarts. He just wanted to stay at home quietly to recharge. If he encountered danger, he would immediately take Natiya and Xiri away from the world and continue traveling.

Hogwarts is the origin of the Harry Potter world, and all the entanglements of causes and conditions begin in this ancient magic academy.

Entering Hogwarts means staying close to the main line. Xin Sheng, who does not belong to this world, may cause changes in the world line, which will attract the attention of the boss.

Dumbledore narrowed his eyes slightly and explained with a smile: "It is precisely because of this that I decided to put you next to me and observe it nearby."

"Anyway, it's just a one-year job, so it's just an examination of you, how about it?"

In Dumbledore's investigation, Xin Sheng's three-person team seemed to appear in London out of thin air.

Dumbledore asked the Ministry of Magic for the holographic magic images of Xin Sheng, Natiya and Xili, and specially asked an old acquaintance of the American Magic and French Association to compare them.

The result is that no one was found.

Dumbledore has asked the Ministry of Magic in many countries since then, and the answers he got were no different. These three wizards had no trace of their existence before.

Although many of Dumbledore's practices have been criticized, no one can deny his efforts as a white wizard to maintain the security of the international magic circle.

Out of caution, Dumbledore decided to visit and personally confirm whether these three mysterious wizards were threatening to the magic world and the entire world.

Dumbledore's blunt words made Xin Sheng understand.

‘So that’s it.’

Dumbledore's unfathomable strength is known as the strongest white wizard of today's era.

He has the confidence to see anyone's nature through a year of time, and he has the confidence to defeat any visible enemy.

Dumbledore was most worried about the hidden threats, just like the Tom Riddle who had confused the entire Hogwarts.

From Dumbledore's eyes, it can be seen that the old professor has made up his mind.

If they do not agree to his "invitation", the two may fight on the spot because of disagreement.

Xin Sheng didn't know much about the strength of the wizard world, and he couldn't figure out what Dumbledore's strength was like compared to himself.

It is Xin Sheng’s creed to plan and then move.

Besides, he didn't need to break up with Dumbledore, at most he would be a professor of Black Magic Defense for one year under his surveillance.

Anyway, the knowledge left by Yue is engraved in his soul, and it is not so easy to be discovered during daily research, even if this person is Dumbledore.

To take a step back, Xin Sheng's research is not a shameful taboo project, and even if Dumbledore knows about it, there will be no big problem.

There are advantages and disadvantages, and books that can be bought in Diagon Alley have limitations after all.

If he could join Hogwarts as a professor, he would be able to freely read many important books in the forbidden book area this year.

These books are not available on the market.

"Oh~"

After weighing the pros and cons, Xin Sheng spread his hands with a wry smile: "It seems that I am not qualified to refuse?"

“Haha~”

Dumbledore understood Xin Sheng's attitude, and his originally sharp eyes returned to kindness.

"Of course not, but depending on your different reactions, I will make corresponding adjustments to the plan."

"In my opinion, being a professor at Hogwarts for a year is the best choice for you, aren't you?"
