Simulation: Start with one person

Finding another dark wizard hiding place, Snape turned and left.

Among the active dark wizards today, many have already connected with Voldemort's forces, but they are just on the periphery, used to expand their numbers and hide their presence.

He is related to Voldemort and has done many evil things, so he is very suitable for meritorious deeds.

"but……"

Snape looked at the notebook in his hand, "It's an unexpected surprise to get the news about Voldemort."

On the way to find the dark wizard, he happened to know that Voldemort was collecting potion materials.

"The compound potion...what does Voldemort want to do?"

Snape frowned and thought for a while. With such a high demand for a compound potion, did he want all his subordinates to infiltrate a certain force with him?

"...It's not impossible!"

Disguise everyone, then infiltrate an organization, replace it, and then replace people bit by bit.

Gradually replace one organization with another.

"Tell Dumbledore! Let him worry."

With that said, Snape returned to Hogwarts, and then saw the "tragic situation" beside the Black Lake.

The ground cracked, as if several layers of earth had been scraped away.

"What's going on? An enemy is coming?"

With the above doubts in mind, Snape returned to the castle.

Seeing Lily talking to Dumbledore, her cold expression softened instantly.

"Severus, you are back," Dumbledore said.

After telling Dumbledore what he had discovered and guessed, Snape asked, "What do you think?"

"It's possible! Pay attention for now!" Dumbledore said.

"Who is responsible? I don't have time to monitor." Snape refused.

"I will arrange for someone to go." He signaled Snape to be calm, he has someone to choose.

"By the way, there are some things you need to do..."

Chapter 405 Sending Letters

"What's up?!"

Snape frowned upon hearing this. Most of the tasks assigned by Dumbledore were difficult.

"Visit other forces in other worlds and invite them to Hogwarts."

After a pause for a few seconds, Dumbledore explained: "I am planning to hold three schools... no, it is to unite all magic schools to hold a competition to..."

"Fishing?!" Snape used a question, but his tone was affirmative.

"No, it's about strengthening cooperation." Dumbledore corrected.

"Whatever you say." Snape wanted to sneer, but with Lily on the side, Snape was more concerned about his own image, so he didn't laugh.

"Send invitations to other forces. I suggest you ask Fang Rui for help. Not all forces will give Hogwarts face, but they will give Fang Rui face."

Dumbledore said this, and Snape frowned when he heard this: "This is taking advantage of Fang Rui! It's not good..."

"If you explain the matter clearly and don't hide anything, how can you say it's taking advantage or asking for help?"

Snape did not continue to argue about the matter and went to Fang Rui to relay Dumbledore's request.

"Okay." Fang Rui nodded slightly and said there was no problem, "But how are you going to send the invitations? Are you going to come in person or ask me to send the invitations on your behalf?"

"Of course I will come personally." Snape said.

After all, Dumbledore ordered it, and the principal's order must be carried out.

"Emmm..." Fang Rui tilted his head and thought for a while, then suddenly said, "I'll be with you."

It happened that he had something to do and wanted to go to other worlds, and Snape could be his companion.

Speaking of which, my travel plans... seem to be changing.

Since Dumbledore wants to entertain people from other worlds, he will definitely arrange some activities. If he helps plan some, it can be regarded as making a travel plan, right? !

"Let's go now, do you have any objections?"

"Yes!" Snape nodded immediately, "I haven't prepared the invitation yet."

"Tsk!" Hearing this, Fang Rui was speechless.

"After all, it is a formal invitation. The invitation letter must be formal and the materials used must be of high quality."

Snape explained, "The corresponding preparations will take some time, half a day... give me half a day."

"Okay! As soon as possible..."

It was okay to wait a while, he could do something in the meantime.

With this in mind, the two separated. Fang Rui went to Dumbledore's room to talk to him about the tournament.

"Regarding the broadcast of the competition, are you going to use magic or alchemy technology to achieve it?"

"If possible, I would like to use alchemy technology."

Dumbledore was a little surprised that Fang Rui suddenly came to talk to him about this, but what Fang Rui mentioned was indeed what bothered him, so he spoke out.

The competition is an opportunity to promote new things. If given the opportunity, he would certainly hope to take this opportunity to bring new changes to this world that has not changed for a long time.

"Do you have any contact with Nico Mele?" Fang Rui pushed things forward.

"Yes, Nico should have received the letter I sent him, and he will probably come to Hogwarts soon." Dumbledore responded.

Before the words finished, green fire erupted from the fireplace nearby, and a strong man walked out of the fireplace.

"Floo Network, the experience of using it is really bad, can't anyone improve it?"

After experiencing the portal, Nico Mele was a little dissatisfied with the teleportation experience of the Floo Network.

"You can improve it!" Dumbledore said.

"Me? I don't have the time to improve the Floo Network." Nico Mele refused without thinking.

"Tell me why you are looking for me."

Without saying any useless words, Nico Mele asked straight to the point.

"I need your help with something..."

Before Dumbledore could finish speaking, Fang Rui interrupted: "I need you to make a broadcast tool version of the alchemy equipment, as well as a tool that can bring convenience to life."

"What do you think of mobile phones? Can you make an alchemy version?"

"If it's an ordinary mobile phone, I can make it. I've been studying technology recently." Nico Mele didn't care why Fang Rui was here. He followed the topic Fang Rui raised and thought about it... …

"But if it's a smart phone, I can only say...no chance! My research on technology is not proficient enough to transform it with alchemy."

"Step by step, you can make an ordinary mobile phone, which is beyond my expectation."

He did not expect that Nico Mele could actually make mobile phones. He mentioned this matter to give Nico Mele a goal.

Then, Dumbledore explained what he planned to do in the Tournament.

"Change?...I support your actions, but I don't have much confidence in whether you can create an alchemy version of the broadcast tool in a short time."

In his haste, he was unsure.

If there was no time limit, he would have enough confidence.

"It's okay, Fang Rui will help." With that said, Dumbledore looked at Fang Rui, asking for an answer.

"It's fine if you want me to help, but my alchemy level is actually quite average, so I may not be able to help."

He has many skills, including the alchemy of several worlds. But mastering it is one thing, and how well he can use it is another.

"I suggest you make two preparations. If you don't have alchemy tools, use magic instead..."

"Yes, I know." Dumbledore nodded slightly and then said, "I also need your help regarding magic."

One thing is for sure, given him some time, he might be able to create a spell for broadcasting, but it would definitely not be as convenient and clear as the magic used by Fang Rui.

"I will help." Fang Rui did not refuse, but he also gave his opinion, "I need your help with some things. Prepare more entertainment activities, hot springs and food, etc. All arrangements..."

After a pause, Fang Rui added: "As for the food, I suggest you invite chefs from other regions... No, it is a must!"

"...Okay!" After a moment of silence, Dumbledore nodded in agreement.

He has traveled to other countries before and knows the differences in food between countries.

One thing is that he doesn't like local food very much either.

But I have been eating it for many years and I am used to it.

but……

Since Fang Rui said so, just agree to his request!It's not something important anyway.

If there is a recipe, a house elf can easily learn it.

As for where to get the recipe, I need to think of something...

"I've finished what I wanted to say. See you later."

With that said, Fang Rui left the principal's office.

Nicol Mellor and Dumbledore began a conversation about the alchemical tools that needed to be crafted.

Half a day later, Fang Rui and Snape set off for other worlds. The invitation letter prepared by Snape was made of paper made of special plants, and the ink used for writing was a magic potion that could calm the mind.

"The first world, where are you going?"

"The Nautical World."

In previous gatherings, each world had its own code name.

By the way, Fang Rui has some suggestions on what to choose a code name. For example, the world where Garp and others live is called "Navigation World", and the world where Satila and others live is called "Zero World", or "Witch" world".

'I seem to go to the sailing world a lot lately...'
