But now the two of them have no time to think about it, they have been exposed.

What happens when two Gryffindors appear in a Slytherin common room?

I knew it would be miserable if I thought about it with my feet.

So the two jumped up at the same time.

"You've mistaken someone!"

Harry grunted as he and Ron swooped across the Slytherin common room and rushed towards the stone wall - strangely Malfoy just looked at them with a strange smile and didn't stop them, Harry knew that if Malfoy did, they wouldn't be able to get out of the Slytherin common room - there were some Slytherin seniors present. As long as Malfoy stopped them with a spell or shouted loudly, they would have to count on Professor McGonagall or Headmaster Dumbledore to save them.

But in any case, it's a good thing that Malfoy didn't do it.

The two of them ran down the hallway, hoping that Malfoy wouldn't chase them out. Harry could feel his feet slipping in Goyle's big shoes, his body shrinking, and he had to lift his clothes. They surged up the steps and into the dark foyer, where they had to hurry back to the Gryffindor common room.

"What's going on? The effects of the drug passed so quickly, and I can guarantee that there was definitely not an hour. ”

Seeing that there were no pursuers behind him, Harry slowed down.

"God, God knows, I think there should be something wrong with the compound decoction made by George and Fred, although the two of them are smart, but they have always been sloppy in their work, maybe they have made some inferior products, and the effect is discounted."

Ron gasped, "Harry, we can't slow down, we'll be doomed if Malfoy catches up with them." Hurry back to settle accounts with George and Fred! ”

To speed things up, they threw down their ill-fitting shoes and ran up the marble staircase in their socks, when they were stopped by someone just as they were about to return to the portrait of the fat lady.

"What are you two playing? Running barefoot in a castle in such fat clothes? Obstacle course? ”

It was naturally Luo Cheng who spoke, and he kept staring at these two reckless children.

"Professor Luo Cheng!"

Harry's heart was put down again, it was "his own man", with the professor present, even if the Slytherins caught up, he was not afraid, and he was back in the Gryffindor common room in a few steps, and those vipers did not dare to come.

"Did you get any news from Malfoy?"

Luo Cheng asked, although he had been hiding his form with the illusion charm to follow the two of them, he couldn't follow Harry and the others into the Slytherin common room, and if he wanted to know what was wrong with Malfoy, he would have to ask Harry and Ron.

"No, before I could say a few words, the compound decoction was invalid!"

Ron hurriedly replied that they trusted Luo Cheng very much, because this idea was actually given by Luo Cheng.

"Failed?"

Luo Cheng raised his eyebrows, the compound potion did have an expiration date, but he stared at it the whole time, Harry and they didn't take much time from coming out to entering the common room in Slytherin, there was no reason for it to expire so quickly.

"How much did you drink?"

"Just one drink."

"That's strange, a cup of compound decoction should be enough, maybe the compound decoction you make is not effective, in fact, drinking a little more can also prolong the effect of the medicine."

Harry and Ron instantly turned bitter, the taste of the polyjuice decoction was too unpalatable.

"Forget it, it's too late to say that. Didn't you get any news from Malfoy? Is there anything unusual about him? ”

"He seemed to know from the beginning that we weren't Goyle and Crabbe."

Harry said with a frown.
