Rubik’s Cube Heavens

　　 The feeling of big ups and downs came too fast, and through so many levels, how high the expectations of the finish line were before, now the three people are disappointed in their hearts.

　　 Kewen knew what should be in this terminal room if normal, so he understood when he saw that the room was empty, and he came here early.

　　 Obviously, Dumbledore has not released the ‘Mirror of Eris’ now, and the ‘Sorcerer’s Stone’ is naturally also not here.

　　 After having guessed, Kewen simply stood at the door and didn't move, while the twins did not give up and searched everywhere, wanting to see if there were any other mechanisms here.

　　 It's a pity, more than ten minutes, enough time for the twins to check every floor tile and wall joint, but they still found nothing.

　　 "Hey..." George stood up and sighed helplessly: "Is that the way it is? Then what is the reason for the difficulties we have overcome before."

　　 Fred was also disappointed, and asked Kewen: "Kewen, what about you? Anything to find?"

　　 "No." Kewen shook his head: "It is estimated that we have come early, the last thing about this level, maybe the principal is not ready yet."

　　 "Well..." Fred accepted Cowen's guess, and then stretched a little tired.

　　George had returned to Cowen at this time, turned around and looked at the whole room again, then chuckled and said, "But it's not without gain, at least the expedition tonight is very successful for us."

　　 "That's right!" Fred also quickly changed his mind, and walked towards the door with a smile, and said with a chuckle: "At least it opened our eyes tonight."

　　 "Should we go back?" Kewen asked the twins.

　　 "Let's go, let's go, it just happens to be a little sleepy." George turned around first, and said while returning to the path.

　　 Fred followed and said with a smile: "It's time to go back to bed. Tomorrow morning is Snape's potions class. I don't want to be caught by him and deduct points."

　　 Kewen smiled and shook his head slightly. Today's adventure is really anticlimactic, not a successful punch-in.

　　 stepped to keep up with the twins, and soon the three of them returned to the room where the potion was placed.

　　 The twins turned their heads to look at Kewen, waiting for Kewen to extinguish the purple flame on the side of the retreat.

　　 Kewen was about to step forward, but suddenly he stopped, and after turning his head to look at the potion bottles, a thought suddenly popped out in his heart.

　　 Therefore, he immediately took out the paper and pen from his pocket where he had cast the ‘Non-mark Stretching Curse’, and then he bent over and wrote on the wooden table.

"what are you writing?"

　　 The twins inquired in unison, and they leaned over and watched, but because Kewen was leaning over to write, they did not see the content.

　　 Hearing the words, Kewen continued to write while responding: "You can't do it for nothing, I also leave a checkpoint here."

　　 After listening, the twins looked at each other, and then they showed very interested expressions, and their smiles gradually became wicked.

　　 Soon Kewen wrote the note, put the note away on the table after putting away the pen, and picked up the note that suggested the correct potion.

　　 The twins couldn't help their curiosity at this time, and immediately picked up the note left by Kewen, and their two heads got together to watch the content on the note.

　　【52-23+2*cos30*tan60-3√2sin45-3!-C(4,2)=? 】

　　【The explanation of the potion and the method of crossing the flame are under the floor tiles corresponding to the answer to the question. 】

【warn! warn! 】

　　 [Only the floor tiles corresponding to the correct answer can be opened safely. Opening any wrong floor tiles will cause a powerful explosion! 】

　　George: "..."

　　 Fred: "..."

　　 George and Fred were at a loss when they read the first line of text. At the same time, they raised their hands and rubbed their eyes. Then they looked at the paper. There was still such a mess of things.

　　 "This is...what?" George turned his head and asked Cowen with a face of hell.

At this time, Kewen was engraving numbers on the floor tiles in the room. He turned his head and glanced at the two of them. He smiled and concealed: "That's a math problem in the Muggle world. I accidentally wrote it down when I was making money during the holidays. ."

　　 The twins looked at each other again, and then George immediately threw the paper back on the table as if he felt that the note in his hand was a dangerous item.

　　 Seeing this, Cowen simply greeted the twins for help and helped him use his magic wand to leave numbers on the floor tiles in the room.

It didn’t take long for all the thirty large floor tiles to be left with number marks, and then Kewen used a spell to lift the floor tiles marked with the number [5], and pressed the logical reminder note about the potion onto five. Below floor tiles.

　　 got up and clapped his hands to be finished.

　　 Fred, seeing this, asked puzzledly: "Did you not say on the note that you want to set up an explosion trap?"

　　 "Haha! I'm not a devil." Kewen laughed and said, "I just mentioned it casually, depending on whether the explorers after us believe in the nonsense."

　　 George was sluggish for a moment, and suddenly pointed at Kewen and burst into laughter: "Hahahaha! You are the devil! Hahaha..."

　　 Fred also imagined what would happen here in the future ~www.wuxiamtl.com~ So he couldn't help but burst into laughter, and of course he gloated, feeling a little bit of silence for the latecomers who didn't know who it was.

　　 Next, Kewen once again extinguished the purple flame at the door with ‘All Curse is End’, and the three of them returned all the way.

　　 But staying for a while when passing by the chessboard room, Kewen used the ‘restoration spell’ to restore all the chess pieces to their integrity and replay the positions of all the chess pieces.

　　 In the key room, Corvin added a powerful ‘door lock curse’ to the door lock; in the room where the Devil Net is located, Corvin turned the Devil Net into a rope ladder.

　　 In the end, the three of them carefully put down their movements to avoid waking the three-headed dog, and successfully opened the door and left the test site arranged by Dumbledore.

　　 After leaving the third floor, Kewen did not return to the responsive room to rest. Instead, he returned to the dormitory with the twins and slept peacefully all night.

　　 The following days are very peaceful. Obviously, the professors have not discovered that the forbidden area on the third floor has been crossed. Otherwise, they will definitely come to the trio for inquiries. After all, the trio is exhausted.

　　 In a blink of an eye, school started for two months, and it came to Halloween on October 31.

　　 The food at the holiday dinner is naturally much richer than usual, but it is a bit unfriendly to Cowen, because all the food is sweet.

　　Kewen doesn’t like sweets very much, not to mention the sweets in the UK are very tired.

　　 Therefore, at the dinner party, he can only choose a few foods that are not too sweet and plan to wait until midnight before going to the kitchen to give himself an extra meal.

　　 But not long after the dinner started, suddenly the wooden door of the auditorium was pushed open. This year's Professor of Defense Against the Dark Arts class ran in with horror on his face.

　　 As the visual image appeared, the next moment, the memory in Kewen's mind emerged...
