Because the ground was somewhat smooth, the giant monster's tall and heavy body couldn't stop sliding towards the position where the three of them stood after it fell, rubbing the ground with a harsh 'zizi' sound.

At this time, the twins were in a daze because of the sudden change, and Kewen didn't plan to stop there.

Quickly put away the wand, and then stretched out his hands, Cowen grabbed the huge stick suspended in front of him with both hands.

As if everything had been calculated, at this moment, the troll happened to be sliding to Kewen's feet. Seeing this, Kewen's arms tightened, and then he swung the giant stick and faced the troll with a blank expression. The brain is a moment.

Bang!

Some crisp knocks sounded, echoing in the empty room.

At this time, the troll had stopped sliding, rolled his eyes under Kewen's sap, and his mouth was wide open, apparently passed out before he could even scream in pain.

Throwing away the giant stick in his hand, Ke Wen waved his hand and summoned the group of fluorescent light that was suspended at a high place.

Taking advantage of the light, looking at the bulging bag on top of the troll's head, Kewen turned his head and said to the twins, "It's done, let's continue."

Some of the stunned twins came to their senses after this, and then with a 'his', they gasped in unison.

"Merlin's forehead..." George couldn't help raising his hand to touch his forehead: "That must hurt!"

Fred joked: "Kewen, are you the troll?"

Cowen rolled his eyes at Fred, then took the lead and walked to the next door, while the twins jokingly followed.

Before opening the next door, the three of them raised their guard this time, lest there be any more dangerous creatures in the next room.

But they all guessed wrong. There was only one table in the next room, and there were seven potion bottles of different sizes on it.

Seeing this, the three of them put away their precautions, stepped into the room, and went straight to the table.

Just as he was about to carefully observe what the medicine bottle was on the table, suddenly, there was a sudden 'bang' at the door in one direction, one behind the other, and two walls of fire of different colors rose in an instant.

The purple flames blocked the wooden door of the retreat, while the black flames blocked the forward wooden door.

The sound of the explosion of flames suddenly broke the silence in the room, startling the three of them, but after seeing the situation clearly, the three of them were dumbfounded.

Because compared to the previous level, this level in front of me seems to give people no way out.

Because of the firelight, the originally dark room became brighter, and Cowen simply stopped the 'fluorescence spell'.

After looking at the twins, everyone turned their heads at the same time and looked at the table in front of them, looking for clues to clear the customs.

And the clue is obvious, written on a note on the table.

George was about to reach for the note, but Cowen quickly reached out to stop it.

"What's wrong?" George wondered.

"What if there is a trap?" Kewen reminded cautiously: "Or maybe the note is painted with poison or something, so be careful."

"Okay." George listened to Kewen's reminder with kindness: "Then it's alright if we look closer, right?"

"No, I have a better way."

As Cowen said that, he tapped the note with his wand, and the "word projection spell" he had learned from Snape had finally come into play.

Following his movement, a piece of orange magic light suddenly jumped out from the note, forming a text in the air.

Fred couldn't help but read it.

The meaning of the whole text is to tell the passers-by that among the seven bottles of potion on the table, there are three bottles of poison and two bottles of nettle wine.

Of the remaining two bottles, one allows one to leave through the purple flame behind, and one allows one to continue through the black flame.

The text is a guessing game, with four prompts, such as the third prompt stating: Among the seven potions, the largest and smallest two are safe.

Combining all the four prompts, Kewen instantly guessed that the potion with the largest bottle could allow people to return, and the potion with the smallest bottle could allow people to move forward.

With this level of logic, I'm afraid even elementary school students can't be fooled.

However, Cowen quickly came over again. Isn't the Harry Potter trio just the age of elementary school students.

At this time, George and Fred, who were very flexible, quickly guessed the answer based on the prompt.

After comparing the results, George said: "There is a problem, there is only a small bottle of potion that allows us to move forward, I am afraid that only enough for one person to drink it and then move on, and the potion of the large bottle is enough for the three of us to return, then What should we do now?"

"What can you do?" Cowen asked.

After George and Fred looked at each other, they all shook their heads to express their helplessness.

Seeing this, Kewen said again reliably: "Let me try it anyway."

The twins readily agreed, waiting expectantly for the almighty Kewen to overcome the problem.

Kewen didn't move the potion on the table, but stepped forward directly, before the flames that blocked them from going to the next level.

After observing the situation and comparing the knowledge in his memory, Kewen secretly said "sure enough" in his heart.

Originally, after seeing the black flame, he thought it was a fierce fire, but now after observing the combustion of the flame, he found that it was not.

After all, this forbidden area was set up to exercise Harry Potter, and it was impossible to use a dangerous flame that would only extinguish itself after everything combustible was consumed.

If it was the kind of fierce fire that seemed to have a soul, I am afraid that the flames would have burned the table to ashes by itself, and then rushed towards the three of them.

After confirming the guess in his heart, Kewen squatted down, held his wand upside down, and then stabbed the wand to the ground.

At the same time, Kewen gave a low voice: "All curses are over!"

This is the top-level spell in the 'Ending Spell' series, and its effect surpasses that of 'Spell Stop' and 'End of the End'.

With Kewen's spellcasting, with the tip of the wand as the center, lightning-like magical radiance quickly spread to the flames, and soon completely wrapped the wall of fire.

The next moment, the black wall of fire suddenly became shorter, the flames seemed to flow backwards, and soon they got back to the ground and disappeared.

"Nice job!" George cheered.

"Is all spells ending?" Fred laughed excitedly: "I learned another useful spell!"

Kewen has always been willing to help the twins improve their strength. Unless it is some more dangerous spell, Kewen will not hide it from the twins.

Therefore, Kewen didn't care about Fred's stealing behavior, and after getting up, he greeted them to move on.

Passing through the wooden door again, the three of them saw another hall in front of them.

But this time the hall should be the end, because there is no second door in it.

Surprisingly, the room was empty and there was nothing in it...
