Chapter 159 Watson and Prince
The Leaky Cauldron, London.

The dilapidated wooden door was pushed open from the outside, and two men in black robes walked in.

Old Tom, who had been barman for decades, received them.

Among the two wizards, the young one had long chestnut hair tied into a ponytail, his face looked a little pale, and his facial features were fairly delicate.

The older one had a hooked nose, a sallow face that seemed to have been suffering from chronic illness, and gloomy eyes, making everyone look ugly.

"You two strangers, what do you call them?"

The young wizard with the ponytail introduced with a smile on his face.

"Ah, we have just arrived in the UK, my name is John Watson, this is my uncle Tobia Prince, we want to stay here for a while, I don't know how to settle the price of the room? "

Tom looked at the combination of their uncle and nephew, and nodded with a clear face.

"How long do you want to live here?"

"We don't know exactly how long it will take. We are traveling around. Recently, we have run out of funds, so we plan to stay in the UK and get some Galleons to continue our trip. My uncle is a potion master , I am very good at configuring potions, so I want to come to Diagon Alley to see if I can find a few potions shops to cooperate with, so I have to live here for at least three months."

Tom heard his words, and looked up and down at the potion master "Prince", and he could indeed see a bit of a master's temperament from him.

"If it's at least three months, then I can give you a big discount on the rent, but you have to pay the rent for three months directly, and then give me another month's money for every month you stay, until you leave until."

"Seven Galleons and four Sikels a month for two rooms. If you pay the rent for three months first, you have to pay me 21 Galleons and twelve Sikels first."

"Watson" has no objection to this price. Strictly speaking, the Leaky Cauldron is the property of the Ministry of Magic, and the owners here are all appointed by the Ministry of Magic.

The price of drinks can be determined by the boss himself, but the room rate is open and transparent in the entire wizarding world, there is no tricks to play on it.

After paying the rent, Tom took them to rooms 11 and 12 on the second floor.

"John Watson" and "Tobia Prince" are, of course, Sherlock and Snape.

The two of them had drawn up false identities in Cokeworth, and Sherlock insisted on not using their real identities, because there is already a Sherlock Forrest and Severus Snape in this world up.

If they still use their original names and appearances, there is a high possibility of problems when dealing with other wizards. It is safer to arrange a false identity to act.

The shape-changing method didn't use Polyjuice Potion.

That potion is okay for temporary use, but if you want to use it all the time to maintain the changed shape, you need to take a sip every one, two or three hours.

Trouble aside, no one can always provide them with available hair to support them in dispensing medicine.

Snape used another potion, not for drinking, but like plasticine, which can conjure a shape according to one's own ideas and attach it to a person's face.

As for the color and length of the hair, it is easy to change. Snape has two kinds of potions, the hair growth potion and the hair dye potion, and after using it once, it will always take effect.

Room 12, Snape and Sherlock are sitting together in this room.

"You keep saying that history cannot be changed, so in the original history, did Watson and Prince really come to the Leaky Cauldron?" Snape said flatly, staring at Sherlock.

Sherlock was flipping through a brochure in the room, which contained introductions and advertisements for almost all the shops in Diagon Alley.

"What I'm talking about is the established and well-known history." Sherlock said while watching, "From now on, we don't have to be too restrained in doing things, just treat ourselves as people of this era. This world is not so fragile , As long as you don’t want to go against something in history, there will be no problem normally.”

Snape was noncommittal to Sherlock's words, and made no further sound with a cold face.

Sherlock didn't get up until he had read all the shops in this era in Diagon Alley in the pamphlet.

"Let's go, we need a stable source of income, the Galleons you and I carry are not too many."

He didn't lie to Tom just now, Sherlock really planned to approach the potion shop in Diagon Alley, and use Snape's potion dispensing ability to earn enough for their living expenses at this time.

Snape has no objection to this, Sherlock has returned the wand to him, he is still confused now, wants to change history, but has no clue to save Lily back.

We can only follow what Sherlock said, and first cooperate with him to find a way to return to the normal timeline. If we can find it, we can only talk about it after trying it.

The two of them came to Diagon Alley in the summer of 1977.

This place looks no different from what it was 16 years later. Most of the shop names are familiar, but there are not as many pedestrians on the street as before, and many wizards have stern faces and worried looks.

Combined with the current situation, this is the largest commercial street in the British magic world, and the current scene can also be explained.

Together with Snape, Sherlock quickly found a potion shop - the finished product store of extraordinary potions.

This shop was chosen by Sherlock among the three finished potion shops in Diagon Alley. The reason is actually very simple. It has the shortest opening time, less than five years.

There must be pharmacists in the shop who can always provide finished potions, but they must be very scarce in high-end sources. A wizard who can be called a potion master is a truly cherished species in the magic world.

The owner of this potion shop is a middle-aged witch who looks quite charming. After Sherlock explained his purpose, she showed obvious interest.

"I want to see your finished potion."

Snape expressionlessly took out a bottle of intelligence enhancer from his pocket, which was one of the stocks he carried with him, a potion that could make a wizard's thinking clearer.

The formula of the intelligence enhancer is very common, and the materials are also common, but it requires a lot of skill from the pharmacist, which can best reflect the level of the pharmacist.

Being the owner of a potion shop, this witch is naturally an expert in potions.

She opened the potion, and just by smelling the smell and observing the quality of the potion, she could already tell the level of the maker.

"If you can guarantee that the potions produced can reach the same level as this bottle of intelligence enhancer, then I will provide the materials. I can give you [-]% of the profit after deducting all costs for each potion."
