Xiao Han had thought of many ways to enter Hogwarts to steal books, but they were either difficult to implement or dangerous.

Later, he stumbled upon the books written by Gilderoy Lockhart on the desk, and a plan could not help but come to his mind.

Xiao Han thought that in the Goblet of Fire plot year, Voldemort's loyal minions, Barty Crouch Jr.

In the third year after Harry Potter entered the school, the new Hogwarts professor of Defence Against the Dark Arts, a former Auror, and one of the leaders of Dumbledore's Order of the Phoenix, Alastor Moody, attacked and disguised him when he went to Hogwarts to take up his post and became a professor of Defence Against the Dark Arts at Hogwarts.

For a whole school year, if he hadn't taken the initiative to expose it, otherwise even Dumbledore, Moody's best friend, wouldn't have found out, this is an impostor.

Xiao Han didn't think that Barty Crouch Jr., one of Voldemort's most loyal minions in the wizarding world, would delve into acting in the Muggle world, study books such as "The Self-cultivation of Actors" and "The Psychology of Performing Arts", and then have the skills of an actor.

Even Barty Crouch Jr., a Death Eater madman, can succeed, and it makes no sense that he wouldn't have a chance.

This was Xiao Han's idea at that time.

So Xiao Han thought of a plan to impersonate Gilderoy Lockhart and become the Defence Against the Dark Arts teacher at Hogwarts for the next school year, and then steal the books in the Hogwarts library as a teacher.

Of course, this is also because Lockhart is a big straw bale that does not live up to his name, and he is simply a rookie, and he is extremely easy to deal with.

With Xiao Han's current strength, he can easily subdue Lockhart.

If it was replaced by other powerful wizards, Xiao Hanke would have to consider it.

It's not that Xiao Han won't be able to beat, with the ability he has, as long as the source point is enough, one-on-one, no one in this world will be his opponent.

It's just that those elite wizards have a lot of combat experience, and in this regard, Xiao Han is much worse than them.

In fact, Xiao Han's combat experience is very lacking, and if he is facing those elite wizards, there is no complete guarantee that he will be able to subdue the target in secret.

If it's just about killing the target, it's much simpler.

But let's not talk about it, whether Xiao Han can get by, the heart of indiscriminately killing innocents, he wants to disguise others, at least he has to know this person's personality, behavioral characteristics, etc., otherwise he will have to be exposed in minutes.

It just so happened that Xiao Han knew who the Defence Against the Dark Arts professor at Hogwarts would be in the next school year.

Moreover, Gilderoy Lockhart, who took this position, is another straw bag with little strength, so it is only a question of how to better disguise it.

This way, he can enter the Hogwarts library in the open and look through the books in the forbidden section.

After all, even Hermione, with the signature of Gilderoy Lockhart, who had stolen it, was able to enter the forbidden area and take the "Powerful Potion" inside out of the library.

That's not to mention Lockhart himself.

And the plan to disguise Lockhart and become a teacher of the Defence Against the Dark Arts class at Hogwarts took some time, and Xiao Han had already solved those pre-preparations.

Gilderoy Lockhart's address is not difficult to solve, as a big celebrity, and he is a who likes to put on a show, just ask around, and you will know where he is signing books now.

Shohan then sent his pigeons and rats to track Gilderoy Lockhart and learn where he lived and how he traveled.

The compound decoction had already been prepared, and this was bought by Xiao Han from Bogin Bock with a different identity.

Compound decoction is not a very rare potion, but because of the material, it will be more expensive, and the actual preparation is not too difficult.

However, as long as there is a golden Galleon, the acquisition of the compound decoction is not a problem, and it is not a magic elixir, that kind of magic potion is real, and money can't buy it, even Bojin Bock doesn't have it, otherwise, he really wants to buy a copy and try it.

After Xiao Han analyzed the ingredients of the compound decoction, he could use Yasha Baoyu to spend the source points to make it without restrictions.

It also saves him to buy a large amount in the future, and attract the attention of others.

Gilderoy Lockhart's messy house.

Xiao Han took out a small brown glass bottle from his pocket, unscrewed the wooden cork on it, put a hair plucked from Lockhart's head into it, plugged the cork again, and shook it vigorously a few times.

Now, as long as he drinks this bottle of polyjuice decoction with Lockhart's hair, he can transform into Gilderoy Lockhart.

But before drinking, Xiao Han looked at the bottle in his hand, and then at Lockhart, who was standing aside and had been standing respectfully because he didn't have his own orders.

He thought that he would have to drink this potion every day for a long time after that.

The effect of the polyjuice decoction will vary greatly depending on the maker.

And the duration of his bottle of compound decoction was only one hour.

Well, that is, he has to drink 24 bottles a day.

Each bottle has a Lockhart's hair, and over the course of a year, you can't eat 8,760 Lockhart's hairs.

Looking at the shiny blonde hair on Lockhart's head, Xiao Han felt a burst of nausea!

"For the sake of the source, fight!"

Grunt, just take a sip.

"Uh~"

Xiao Han hiccuped, and before he could recover his senses, he saw that his body suddenly changed, and after some ups and downs, another Gilderoy Lockhart appeared on the scene.

In the room, except for the difference in clothes, the two Lockharts, who couldn't tell the difference at all, looked at each other from each other.

……

The position of Defence Against the Dark Arts teacher at Hogwarts is rumored to be a position cursed by Lord Voldemort.

Voldemort had wanted to be the teacher of the class, but Dumbledore refused, and from then on, such a rumor was born.

No one can stay in this position for an entire year and continue to teach.

In the beginning, there were many excellent wizards who did not believe in evil and applied to become teachers of this course at Hogwarts.

But as the rumor goes, these wizards will always be unable to continue teaching for various reasons when they are about to teach for a year.

Some people even encountered danger and almost died.

As a result, this rumor, which was originally just a joke, intensified, and everyone was telling all kinds of legends about this rumor.

As a result, no one wants to be the teacher of the Defence Against the Dark Arts class at Hogwarts.

Every year, Dumbledore had a headache over hiring another teacher who was qualified to be a Defence Against the Dark Arts class.

Later, Dumbledore had to invite the wizards who had graduated from Hogwarts in the past.

There will always be some nostalgic who will agree to Dumbledore's invitation.

However, in the future, these people will also be unable to continue teaching for various reasons, resulting in the position of Defense Against the Dark Arts class teacher, which is becoming more and more difficult to recruit.

In particular, this school year, when Harry Potter entered the school, Voldemort reappeared, and possessed Professor Quirrell, the teacher of Defence Against the Dark Arts, causing a series of events that eventually led to Professor Quirrell's death.

Other things can be hidden from the public, but Professor Quirrell's death is a fact that cannot be concealed.

As a result, in the next school year, Hogwarts' Defence Against the Dark Arts teachers will be completely unable to recruit people.

As a last resort, Dumbledore advertised in the Daily Prophet to see if anyone would be willing to take the position.
