The Gianna Proudmoor in front of them was not the "new" Gianna, it was the Gianna they knew who was currently Dalaran's diplomat in Winterfell City.

From time to time, diplomats like Gianna and Sylvanas would return to their own world to report on the situation.

Winter Town has been upgraded to Winterfell, Baron Glamorgan has been promoted to Earl Glamorgan, and the territory under his name has also expanded countless times, all of which must be reported.

However, Sylvanas will go straight back to Winterfell after reporting the situation. She figured it out, she didn't want to be the queen of the High Elf Kingdom, there was no need to get involved in those things, hide in Winterfell and be an honest diplomat, and when Kael'thas became the king and her status and reputation were stable, she could continue to be her Ranger General.

Anyway, the High Elves have a long lifespan, and there is no need for her to dwell on the short time of these ten years.

Gianna's situation is different, she is a disciple of the archmage Antonidas, because of the various changes, Dalaran has not been invaded by the Scourge Legion, and the entire city is still intact in its original location.

Many of Dalaran's mages are also alive and well, and they are still a major force in the world of Azeroth.

Gianna herself is also the princess of Kul Tiras, so she has a lot of places to run every time she goes back, and even if she has a teleportation spell, she has to spend a lot of time dealing with various things.

Occasionally, in her free time, she ponders the difference between the two worlds and how she can travel freely between them according to her own abilities.

This was the case this time, Gianna, who was about to go to Lordaeron to find Ferdin, was thinking about how to use her magic to get to Winterfell when she suddenly came to Winterfell.

「……」

After listening to Gianna's description, David was speechless.

Gianna said a lot, which was equivalent to not saying anything, and she didn't know how she did it, but judging by her description, it seemed that she had acquired similar abilities to those of Ferdin.

"Test a few more times to see if you're really free to travel back and forth?"

"Hmm!"

Gianna is also very concerned about this matter, although she still can't figure out the principle, but as long as she has this ability, it is much easier for her to study.

Gianna tried a few times in front of David, proving that she was really free to travel back and forth between the two worlds.

Seeing this, Tony also began to try, but as before, there was no way to return to his own world at will.

"What's going on?"

Tony pondered quietly for a few seconds, and when Gianna returned, he asked her a few questions, such as if she had any energy fluctuations when she completed the crossing. Or mana drain or something?

After getting a negative answer, Tony began to sort through the various information of the two people again, looking for differences.

His mind was spinning quickly, and he quickly thought of a key difference, and it was related to Winterfell.

"Identity!"

Not only did Tony think of it, but David and Gianna also thought of it: compared to Gianna, a diplomat in Winterfell, Tony didn't have any "official status" in Winterfell.

In order to verify this guess, the three people immediately went to find Renault, Sylvanas, Medivan and others for testing.

This was soon confirmed.

Diplomats such as Renaud and Sylvanas have gained the ability to travel freely between the two worlds; And a person like Medivan, who is purely a guest, has no way to come and go at will.

Later, several people went to find Jack Kraussa and Sheldon and others, Jack Krausa has the official status of a firearms instructor and a knight of the Winter Knights, and also has the ability to travel freely.

Howard, Sheldon and others have the official status of alchemist, engineer, scientific advisor and other official identities of the Winter Alchemy Workshop, and Sheldon also joined the Winter household registration for the first time, and at this time also gained the ability to travel back and forth at will. z.br>

On the contrary, Penny, although she has an estate in Winterfell, she does not have a Winter household registration and does not have any official position.

So it still needs Leonard to take it back and forth.

"So I'm just a black guy in Winterfall?"

Petunia didn't care much about whether she had a Winterfell household registration or not, after all, whether she had a household registration in this world didn't seem to matter to her.

Now it's different, people with identity and household registration have gained "superpowers", which makes her seem to be an outsider - from the perspective of household registration and other aspects, she can indeed only be regarded as an outsider now.

"I want to get naturalized!"

Penny said on the spot that she wanted to become a Winter, and in the future, she would be an authentic citizen of Winterfell, and she would die in Winterfell, be buried in Winterfell, and become a female ghost in Winterfell!

Naturalization or something is not a big deal, David went directly to Weatherby Swan, registered Penny on the spot, and archived Penny's personal information.

After doing this, David asked Penny to test it out if she had gained the ability to travel between the two worlds freely.

The result was a bit unexpected, after Penny obtained the Winter household registration, she still didn't get the ability to travel back and forth between the two worlds at will, which made Penny very depressed!

David didn't think about it for long, and immediately added Penny as an assistant to the ceremonial officer, and Penny immediately had the ability to travel back and forth between the two worlds.

"It seems that it's not just Winterfell's household registration."

Through a series of tests, he already knew that Winterfell's official position could give these xenoplanes the ability to travel back and forth between the two worlds.

While there are still some limitations, it will be easier for Winterfell to communicate with many worlds;

Through this change, David wondered if he could recruit more talent across planes if he issued something like visas? Isn't it easier and faster to recruit people?

With a visa or proof of permission to enter Winterfell, these people can come directly to Winterfell, which is certainly much more efficient than having to go back and forth with a specific person.

If this method works, maybe a facility similar to the immigration customs can be built to play the effect of an interdimensional teleportation array?

David was about to test them all, but as soon as he turned his head, he saw Tony staring at him.

"What?"

"Ahem!" Tony cleared his throat, "What do you think of me being Winterfell's Chief Scientific Advisor?"

"Yes!"

Tony didn't want to hang any title in Winterfell, he felt that it was more free, he could come and go as he wanted, and he wasn't so closely involved with Winterfell.

But now in this situation, Tony feels that he can't afford not to have a title, and even has to apply for naturalization to become a real resident of Winterfell.

"Or, you're going to knight me or something?"

"What? You want to swear allegiance to me?"

「……」

As soon as Tony heard this, his whole body shook, so he decisively skipped the topic, and only asked David for a chief scientific advisor and Winterfell's household registration.

Later, David returned to his office and asked Eva to retrieve the information and household registration of some important people in Winterfell.

These materials are usually kept at hand so that David can view them at any time.

Almost as soon as David gave the order, Eva walked in with the papers.

Flipping through the papers, Winterfell's household registration information is divided into several sections.

Among them, locals, non-natives, officials and civilians have corresponding folders, such as Eva and Helen, and Tony and Sylvanas, which are in different categories.

Put aside the documents that record the information of Ferdin, Eva and others, these people themselves have the ability to come and go at will, and their household registration and position will not give them additional bonuses.

Davy focused on information on people like Tony Stark who had come to Winterfell indirectly and were of great value to Winterfell at this time.

Tony is now a naturalized citizen and will become Winterfell's Chief Scientific Advisor;

In addition to Tony, Jack Kraussa has long been a member of the Winter Knights, more

It was a knight who had already sworn allegiance to David.

Who else is there?

Sheldon and the others have official identities, and Sheldon has also done an official household registration, in fact, the household registration forms currently used in Winterfell are all blueprints made by Sheldon.

In addition to these people, it seems that it is not very important whether the rest have the ability to travel freely?

"That's right! I almost forgot about Optimus Prime."

David is going to find a time to ask Optimus Prime what position he is going to hold? As for Megatron, he will be the commander of the Cybertron Legion.

"By the way, what has Optimus Prime been up to lately?" Although he had returned to Winterfell from Snowy Castle in Optimus Prime before, the situation at that time was not suitable for the two to chat, and if he wanted to inquire about Optimus Prime's recent situation, he had to ask Eva.

"It's like learning the Light with Liadline and the ambulance."

"What? He wants to be the first Cybertron Paladin?" With Optimus Prime's character, he should be able to learn the Holy Light soon, but I don't know if I should give this Cybertron Paladin an extra set of armor and weapons?

While chatting casually with Eva, he took out an ordinary piece of iron and used alchemy to make an iron plaque.

The plaque is plain, with a wolf's head emblem symbolizing Winterfell on the front and "Permission to enter" on the back in the Brennian lingua franca.

He was going to try it out with this token, as for who would test the effect of this item......

"Helen! Give this to your father."

After telling Helen about the possible effects, Helen immediately returned to the Kingdom of Sparta to find her father Tyndareus, and soon came to an accurate conclusion: the token did have the function of bringing people to Winterfell!

Helen's father, Tyndareus, took the token with him and gained the ability to travel freely to Winterfell, but when he gave it to the others, he lost it.

"This token will be handed over to your father for safekeeping, you have been here for a long time, and if something happens over there, you can also use the token to notify you."
