Xiao Han stood on the edge of a platform and began to ponder the map on it.

He walked aimlessly for a while, and on the platform on the side of the road, he found a map of the city, and began to look at the map.

Xiao Han fell into thought.

The easiest way to obtain the source point is to directly transform the substance through the artifact.

Any substance can be transformed, even air can be converted into a source point.

However, this method of converting air is very convenient and can be done anytime, anywhere.

However, the number of source points that can be obtained is really limited, and it is not necessarily possible to get a few points at the end of the day.

And when transforming, because of the sudden lack of air, it will also cause the surrounding air pressure to change, if for this reason, he suffocates to death, it would be too funny.

He can also stand directly in the sea and transform into seawater.

This method is also very convenient, and the efficiency is higher than that of converted air, and the source points can be obtained more.

But it's not that high.

The source points that can be obtained by transforming these low-density substances are really limited.

According to the conversion rate of the artifact, the rarer the substance, the higher the density, the higher the energy it contains, and the higher the mystery of the substance, the more source points it will get from the transformation.

Really rely on this method, so that you stay in the sea all day in a daze, just for the inefficient transformation of substances, to obtain the source.

This kind of life is not what Xiao Han wants.

In fact, Xiao Han had the idea of using a small amount of source points to exchange them for a large number of banknotes.

After all, the world we live in now is not a wild and primitive world, and in modern society, money can almost be said to be omnipotent.

He can use these banknotes to buy a large number of rare items such as gold, silver, platinum, etc., and then turn these around to convert them to obtain a large number of source points.

This method is highly feasible and has a high conversion rate, but it is very potentially dangerous.

He didn't have the means to buy precious metals in large quantities.

However, if you only use a small amount of paper money to buy these precious metals, you can buy them at ordinary gold shops on the side of the road, but the number of source points you can obtain is also limited.

If a large number of counterfeit money is used to buy precious metals, not to mention these banknotes, it will not cause inflation, and the disappearance of a large number of precious metals alone will definitely cause economic shocks throughout the world.

When the time comes, all government agencies in the whole world will definitely make every effort to investigate the whereabouts of these disappeared precious metals.

In this way, it is difficult to guarantee that Xiao Han's existence will not be exposed.

For the Harry Potter world, such a modern world with a modern background, as long as you pull out a powerful modern country casually, not to mention whether there are those laboratory-level weapons or not, the conventional military force alone is not something that Xiao Han can resist.

Even if Xiao Han's own strength is stronger than Voldemort and Dumbledore, he has to kneel in the face of the state apparatus.

Even if Xiao Han can summon a champion-level class, in the face of an endless stream of weapons of mass destruction, he doesn't have much confidence in whether the champion classes such as angels and dragons can withstand the bombardment of nuclear weapons.

Therefore, it is good to use a small amount of money, but if you use a large amount of "counterfeit money", it will eventually attract the attention of the state.

Then there must be a succession of troubles, Xiao Han just wants to live quietly, the kind of days full of excitement every day is not what he wants.

Now Xiao Han is a black account, although he has a lot of money, but if he wants to go to the bank to deposit money, he can't do it, and he can't even open an account.

So now, he wants to make an identity file that can be used and is not easy to be found out.

But it is obvious that the station in the UK is not like in China, where there are all kinds of small advertisements for treating hemorrhoids, bag unlocking, applying for fake certificates, and asking for children with a lot of money.

As a former otaku, Xiao Han obviously doesn't know that kind of agent skill that automatically searches for the nearby black market and hidden forces.

Fortunately, the national conditions in the UK are different from those in China, and there is no ID card, as long as you have money in your pocket, it basically does not affect your normal life.

However, Xiao Han has such an obvious Asian face, and his dress and behavior are a little different from ordinary people, but it is very likely that he will be asked to show identification by the police patrolling.

Of course, as a magician, he is naturally not afraid of these policemen who don't even have guns, but after all, it's also a troublesome matter, isn't it?

Fortunately, now is not the time for terrorist activities to ravage Europe in the future, otherwise those martial law, even if Xiao Han is a magician, it is difficult to guarantee that he will not run into trouble.

In fact, Xiao Han was too worried about those ordinary policemen, and a Muggle expulsion charm could solve the possibility of being watched.

But it occurred to Xiao Han that this might attract the attention of the British Ministry of Magic.

After all, London is the headquarters of the British Ministry of Magic, and it is not allowed to perform magic in a busy city like London, and when a large group of Aurors chase after it, it will be troublesome.

At a time when Xiao Han was difficult to make a decision because of his worries.

"There it is!" Looking at the place name on the map of London, Xiao Han thought of the solution*********** Dun Chinatown, also known as Chinatown or London Chinatown, located in the Soho district of Westminster in central London.

Almost half of the Chinese population in the UK live here, mainly engaged in Chinese restaurants, Chinese goods shops and souvenir shops.

However, in addition to those who have official status on the surface, there are also a large number of Chinese black households working here.

Compared with China at this time, you can make more money by working in the UK.

There are many people in China, especially in the Fujian area, who have difficult family backgrounds and will choose to take risks and smuggle here.

As long as they are not found and repatriated, even if they are paid much lower than the average person in Britain, they are often exploited and have no security in their lives.

But as long as you work diligently for a few years, you can save a lot of money than working in China and send it home.

However, where there are people, there is darkness.

Xiao Han believes that in such a mixed place, it should not be difficult to find a way to solve the identity problem.

Chinatown is not too far from the Leaky Cauldron Bar, and Xiao Han took a taxi and arrived here quickly.

said that it is Chinatown, and there are indeed a lot of oriental elements, but in Xiao Han's eyes, he always feels very awkward.

Foreigners' perception of the mainland has always been one-sided, and the white government will not bother to correct the misconceptions of the civilian population at home.

There are even some people with ulterior motives who deliberately spread these erroneous information about the mainland.

Some stubborn elderly people even think that the mainland is still like the Qing Dynasty, and they still have rat braids.

Therefore, in the eyes of people from the mainland like Xiao Han, the decorations of these foreign Chinatowns are really a bit strange.

It was still early, Xiao Han casually picked a Chinese restaurant, ready to fill his stomach first, he hadn't eaten Chinese food for a long time, Yashan World was a Western fantasy world, but there was no food for him to eat.

After coming to the world of Harry Potter, he has been living in Diagon Alley, you know, Britain is known as a food desert, it is conceivable that the food provided in Diagon Alley can be eaten, but it does not meet his taste.

In a Chinese restaurant.

Xiao Han smashed his mouth, this Chinese food in Chinatown tasted weird, it didn't fit the taste in his impression at all, it felt sweeter and more greasy.

"Guest, this sweet and sour pork rib still meets your taste, right?"

It's not a meal yet, and the owner of the restaurant, Lao Chen, looked at this strange fellow who had nothing to do, so he came up to talk.
