Dumbledore's test of Hermione was her brains, and she had to make up for what the team lacked.

It wasn't easy to do, and when Harry and Ron had decided on something in their hearts, it would be difficult for anyone else, even their good friend Hermione, to change their minds in words.

This also made the role of Hermione's think tank much less.

If King Arthur had not been obedient to Merlin, then it is conceivable that his reputation as a wise man would have been greatly discounted.

Now and for a long time to come, Hermione was in such an awkward position.

When encountering things, she is often able to weigh the pros and cons and persuade her friends.

It's a pity that the other two have always been convinced: life and death are downbeat, and if they don't accept it, they will do it......

(Hermione: Enough is enough, destroy, Arvada nibbles all your melons!) ）

As for the room where the trolls are kept, just ignore it.

Inversely proportional to the thickness of their skin, trolls have almost negative magic resistance, and any magic damage is magnified exponentially.

Because of this, this thing is full of fear of wizards in its bones, and when the irascible desire to attack conflicts with the fear deep inside, their chaotic little heads will give orders to attack indiscriminately.

Targets include, but are not limited to, other trolls, rocks, campfires, flowers and trees, any creatures around it, and itself.

If it weren't for Quirrell's tricks on Halloween, there is a high probability that the trolls would not have taken the initiative to attack the wizard, they still have some thinking skills, and no matter how fierce the lion is, it will not rush to the muzzle, this is the instinct of animals.

Dumbledore had envisioned the trolls to be mascots, and if they were stopped, the old headmaster would have to consider taking Harry down another path.

Now, Harry and Hermione are facing a new challenge.

After entering the room, the two of them couldn't help but freeze in place, and in front of them was an endless sea of sand, which looked extremely real.

In the distance, small sharp horns emerged from behind the dunes, and they recognized what they were at a glance.

"Sea of sand, pyramids, have we come to Bill's sand table?" Harry kicked the sand under his feet, it was real to the touch, and the scenery around him reminded him of the style of Bill's office.

"No way, I didn't feel any magic fluctuations just now, we must still be in the room."

The little witch looked around, perhaps the room was enchanted, like the ceiling of the auditorium, but it just looked endless.

"And Bill's sand table is actually a fish tank, if we had entered it, we would have drowned by now." Hermione crouched down and grabbed a handful of sand on the ground, why did it smell faintly familiar?

"The Devil's Net must have been set up by Professor Sprout, and the flying key must have been spelled by Professor Flitvier, and as for the chessboard world...... Harry racked his brain, what professor was particularly fond of wizarding chess?

"Professor McGonagall, I've heard Ani say that our Dean loves alchemy golems." The little witch took over, "Trolls are supposed to be Professor Quirrell's handiwork, and the Self-Defense Guide mentions how to deal with them, which is the domain of Defence Against the Dark Arts. ”

"There's no doubt that the Potions Room is a level set by Professor Snape, and the style of this level is most likely made by Bill."

Listening to the little witch say this, Ani added in her heart, and me.

It was the result of a week of working with Bill, mainly because the dehydration curse was too draining.

They also cast projection magic in the house in pursuit of perfection, which also made it convenient for him to hide in the room.

The ubiquitous fluctuations of magic concealed his existence, and even Voldemort was concealed.

"But how are we going to get through this room?" Harry was a little puzzled, unlike the previous levels, after entering this place, he didn't see the portal on the other side.

"The pyramid over there might be a hint, maybe we can go over and take a look." The little witch finished speaking and took a step in the direction of the pyramid.

"Buzz~~~"

With Hermione's movements, after a buzzing sound, there was a new change in front of the two.

A row of lattices stretched forward beneath their feet, and Harry counted them, seven in all.

There was also a suspicious black mark on the second lattice, revealing a palm-sized piece of cloth that appeared to have been part of a cloak.

Next to the first grid is a bulletin board, with a wooden box underneath.

The two looked at the sign and quickly fell into deep thought.

[Adventurer in the desert, I want to tell you the following here]

[First, the grid in front of you will take you to your destination, but you need to drink 1 sip of water every time you walk through a grid, otherwise the grid will absorb the water on your body.] 】

[Second, you can take as much water as you like in the wooden box, but remember that you can only carry one bottle per person at a time. 】

[Third, whether you drink in large gulps or small sips, the water in the bottle is only enough for you to drink 4 sips. 】

[Fourth, well, there is no fourth, so what are you waiting for? Hurry up and get started, and in 10 minutes the path will be closed to you forever. 】

After reading the last one, Harry hurriedly took out a bottle of water from the box, and couldn't help but complain in his heart, and said that there is no fourth, which is obviously the most important one, okay? It's a time-limited level, can't you be a person?

"Don't worry, Harry, it's just seven squares, we'll be able to get there in a few steps, it won't take long."

Hermione looked at the three rules in front of her, and her heart was a little numb, and it seemed that she couldn't pass it no matter what.

It is known that each person can only carry 1 bottle of water, which means that when they go up to the second block, they will drink 1 bottle of water, and even if the next person does not move forward, the remaining water will only be enough for him to pass through the sixth block, and when he steps on the seventh block, he will be drained.

Unless......

Hermione suddenly thought of Ron, unless one sacrificed himself and gave up drinking water when stepping on the second grid, giving all the water to another.

After passing through the second grid this way, he still has 5 sips of water to drink, and he can pass through all the squares smoothly to reach the destination in front of him.

Thinking of this, Hermione pulled her hair in embarrassment, it was still not right, each person could only carry one bottle, and the saliva left in the second grid could not be carried at all, or at most the sixth grid.

"Hey, what's wrong, Hermione? Let's get started. Seeing the little witch tugging at her hair in place, Harry urged anxiously, knowing that they only had 10 minutes, and now three minutes had passed.

"No, Harry, there's no chance we'll get through. Even if you drink one person's water first, even if all the water left after the second grid is given to you, you will not be able to pass the test. ”

The little witch was even more irritable, there was no one in this room, and the previous group of visitors must have passed, but how did they do it?

"We need at least 9 mouthfuls of water to get one person through all the squares, but we can carry up to 8 mouthfuls of water at a time, so what the hell is going to do?"

Looking at Hermione's anxious way to turn in circles, Harry couldn't help blurting out-

"If you can't bring it once, why don't you do it again?"
