Just became a godfather, and you said this is Hogwarts?

Erwin smiled and said, "Don't worry, Godfather. I value my life very much! If there is any danger, I will come back as soon as possible!"

Snape nodded: "Just keep it in mind. As I said before, don't take risks!"

Snape was still a little worried and reminded Erwin again.

Erwin nodded: "Okay, okay, I understand, Godfather! By the way, Godfather, I have a notebook, can you help me take a look at it!"

As he spoke, Alvin took out the notebook that looked like Hufflepuff's and handed it to Snape.

Snape took it and glanced at it.

His eyes widened instantly: "Such a comprehensive knowledge of herbal medicine, where did you get this from?"

Erwin said, "I found it. Godfather, do you think it's possible that this is Professor Sprout's notebook?"

Snape thought for a moment and shook his head: "Probably not. Although Professor Sprout is the head of Hufflepuff and has done his best in the field of herbs! However, you should also know that every potion master and herbal master has his own unique techniques!"

"It's the same with Professor Sprout. You don't have much contact with Professor Sprout, so you probably don't understand! But we have worked together for many years, and I often need Professor Sprout's herbs to brew potions, so I know some of her special methods!

"Look here, the method of processing the lantern grass in the notebook is completely different from Professor Sprout's method. It's hard to say which is stronger or weaker. In the end, both will produce complete lantern grass, but the method in this notebook can make the lantern grass more complete, and even the easily damaged rhizome can be kept intact!"

Erwin said, "So the owner of this notebook is better than Professor Sprout in herbology?"

Snape shook his head. "Not necessarily. I can only say that it is better than Professor Sprout's in some places. However, some of the techniques in this notebook are old-fashioned. As time goes by, the wizarding world has already found better methods! Many of these methods were discovered by Professor Sprout. It's hard to say which one is stronger or weaker!"

Snape closed his notebook.

"This notebook of yours, isn't it Helga Hufflepuff's?"

Erwin spread his hands: "I'm not sure, but after what you said, Godfather, I think it's very likely. Even if he's not from Hufflepuff, he must be a very old student of Hufflepuff House. After all, you also said that many of the techniques recorded here are very ancient!"

Snape nodded. "How much of this notebook do you know?"

Erwin said, "It's very strange. I have clearly finished reading it and I am confident that I have mastered all the knowledge in it, but every time I look at the contents of this notebook again, I feel that I have new insights!"

Snape said, "Then this notebook must really belong to Hufflepuff. There is a legend in Hogwarts that Hufflepuff once said that knowledge is endless. When you think you have mastered a piece of knowledge, you will have a different understanding when you study it again!"

Erwin took the notebook and put it away.

"However, I still don't understand the significance of this notebook. I guess it should be related to the heritage of Hufflepuff, but I don't have the slightest clue!"

Snape said, "Don't worry. You are so talented. If the Hufflepuff heritage really exists, I think you will definitely get it. Since this notebook can bring you new insights every time, study it carefully! Even if it is not for the Hufflepuff heritage, it is also to increase your knowledge!"

Erwin nodded, "I know, Godfather! It's getting late, I'll leave now!"

Snape nodded: "Well, be careful on the road!"

Erwin raised the corners of his mouth and gave Snape a reassuring smile.

Then he disappeared directly from the spot.

In Diagon Alley, in an office on the top floor of Cavendish Building.

Alvin called Old Tom over and assigned some trivial matters to him.

Then he told old Tom about his plan to go out to sea.

Old Tom was very worried.

But he also knew that no one else could change what Erwin decided.

In the evening, Erwin appeared at the beach.

There is already a ship waiting for Erwin here.

Old Tom prepared it in advance.

There were a dozen or so members of the Cavendish family on board.

Erwin called over the captain of the Cavendish family.

The captain walked into Erwin's lounge.

"Owner!"

Erwin nodded.

Then he took out two maps from the space ring.

"Compare these two maps. I have marked the location of my guess for Blessed Island, but I have never been out to sea, so I don't know if it is correct. Take a look!"

Erwin is not a man who pretends to know something when he doesn't.

He had indeed never been to sea and didn't know anything about sea.

It is clear that none of the captains and sailors specially trained by Cavendish understand this.

To be realistic, if you gave Erwin a sea chart right now, he probably wouldn't even look at it.

So professional matters should be left to professionals, and Alvin never tries to be stubborn.

The captain took the map and took a look at it.

Then he placed the two maps on the table, picked up a pen from the side and wrote and drew on the maps.

Erwin was in no hurry to urge him.

Erwin didn't know where the Blessed Island was.

But he thought of the simplest solution.

That is to believe in science.

The shipping industry is now very developed.

So Erwin simply used the shipping industry to search for it.

In fact, the reason is very simple.

The route taken by Grindelwald and old Robert to sail out to sea, and then the wind direction at the time, their ships and other factors were taken into consideration.

Let professionals calculate.

Calculate their approximate direction and range.

Finally, we found the overlapping locations where the Blessed Island appeared twice.

That must be the Blessed Island.

Alvin also asked old Robert and Grindelwald about this information.

All of this is recorded on the map at this time.

The captain leaned over the table and began to calculate in detail.

About an hour passed.

The captain straightened up.

Erwin turned around and looked: "How is it?"

The captain hesitated.

Erwin said, "Just say whatever you want to say, don't worry about anything!"

The captain bowed and said, "Yes, sir. According to my calculations and the information you provided, I found that there should be no overlap between the two. The place you marked on the map seems to be an overlap at first glance, but if you look closely, it is not the case. The longitude and latitude do not match!"
