After the tall man left, Luo Yu knew that he didn't have the strength to save his sister's soul alone, so he had to look at Yin Feng hopefully: "Since we know that they have lost a soul and a soul, what should we do?" Conjuring spirits? ”

Yin Feng pondered for a moment: "It's not proper, because their souls were captured, it must be under the control of the other party, and the soul summoning is just a waste of effort, I will use the soul attraction method to find the current location of their souls, and then find a way to rescue them." ”

Seeing that Yin Feng really had a way, Luo Yu was shocked and nodded: "Okay, without further ado, do you need to prepare something?" I'll get it. ”

"No, it's just a small spell, but who will cast it?" With that, Yin Feng's gaze swept over the four people lying on the hospital bed, and then looked at Luo Yu.

Seeing Yin Feng staring at him thoughtfully, Luo Yu smiled awkwardly: "Whatever you want, anyone can do it." ”

Having said that, his body moved slightly, just in the middle of Yin Feng and Luo Xue. Who to cast? Luo Yu knew that Yin Feng was teasing him, but he wouldn't give anyone any chance to do anything that might hurt his sister.

Yin Feng chuckled, his laughter was full of contempt, he took out a piece of yellow sheet paper from his pocket, bypassed Luo Yu and walked to Wang Lin's bedside.

Originally, Luo Yu thought that he was going to choose Luo Xue by bypassing him, and the whole person became nervous, but when he saw Yin Feng walking to Wang Lin, he breathed a sigh of relief, and silently recited in his heart: "Amitabha, sin, sin, sin." ”

Yin Feng plucked a few hairs from Wang Lin's head, wrapped them in yellow table paper, and then folded them into a paper crane, and gently scratched a small wound on Wang Lin's eyebrows, squeezed out a little blood, and pointed at the position of the paper crane's eyes, and then, he shook the paper crane with his index finger and middle finger and shook it hard, and the paper crane burned by itself, Yin Feng moved the burning paper crane from head to toe above Wang Lin's body three times, and then withdrew his hand and shouted: "Qiankun borrows the law, the crane leads the way, disease!" With the last word, he threw the paper crane that was about to burn out into the air, only to see a flash of golden light, and the ashes left of the burning yellow paper turned into a small crane, which was covered in golden light, fluttered its wings in the air a few times, and flew out of the window.

Seeing the little crane fly out of the window, Luo Yu and Yin Feng originally planned to jump out of the window directly with it, but there was a guardrail outside the window of the hospital, so they had to resign themselves to running the stairs, but fortunately, it was only the second floor, and their speed was also fast, so they quickly ran out of the door to catch up with the little crane.

Out of the inpatient department, the speed of the little fairy crane's flight slowed down a bit, as if he was deliberately waiting for Luo Yu and them, so that they could easily keep up, the little fairy crane flew and flew, and finally flew downstairs to the thirteen teaching buildings as expected.

Luo Yu frowned, Thirteen Buildings, is it really still here?

The little crane didn't fly in from the window in one breath, but obediently led the way for them, flying up the stairs, Luo Yu and they followed behind the little crane to climb up layer by layer, and when they were a few steps away from the seventh floor, the little crane suddenly stopped, hovered above their heads for a moment, looked at Yin Feng screamed miserably, and then rushed up to the seventh floor as if righteously, and then flew towards the wall where they summoned the mirror fairy with all its might, but its flying posture was obviously not right, it was not so much that it took the initiative to fly away, but it was sucked over.

When Luo Yu and Yin Feng stepped on the seventh floor, they happened to see the little fairy crane hit his head on the spirit gathering array painted by Yin Feng on the wall, turned into a little crystal light, and was sucked into the spirit gathering array.

What's going on? How did the Spirit Gathering Array drawn by Yin Feng absorb the cranes he had summoned by casting his own spells? Luo Yu looked at Yin Feng next to him puzzled: "What's the matter?" Could it be that there is something wrong with the Spirit Gathering Array? ”

Yin Feng shook his head slowly: "No, I have drawn that formation countless times, and there will never be a problem."

Yin Feng was very confident at this point, because this Spirit Gathering Array could gather spiritual energy, and it was very effective to assist in cultivation, so he had painted it countless times since he was a child, how could it be wrong?

Yin Feng walked to the wall and carefully observed the spirit gathering array he had drawn, to his surprise, he actually felt a strange feeling from above, an indescribable strangeness, but he couldn't see anything wrong, could it really be wrong? Yin Feng stretched out his hand and lightly swiped his fingers over the strokes of the formation, and he had to copy the formation again to confirm what was wrong.

Luo Yu watched Yin Feng's movements from the side, but he couldn't do anything, after all, he was completely novice in the formation. Luo Yu, who was bored, saw the fragments of the mirrors on the ground, which they left behind last night, and no one had come to clean them yet, Luo Yu squatted down and picked up the larger fragments little by little and put them in the basin next to them, and then got up and went to the classroom next to them to find a broom, wanting to clean up there.

He walked between the doors of the two classrooms, and then habitually turned and walked into the classroom on the left, and was surprised to find that this was actually the 707 classroom where they recruited the Saucer Immortal last time.

This is the third time Luo Yu has walked into 707, but it is the first time during the day, after walking into 707, Luo Yu feels very strangely that this classroom is very large. Yes, big, a very ordinary adjective, but a very strange feeling.

There are large classrooms in the thirteen teaching buildings, and looking at its layout, each classroom should be the same size, but why do you feel that 707 is so big when you walk in?

Luo Yu walked into the next few classrooms again, and took a closer look, but found that only the two marginal classrooms would give him such a feeling, and the other classrooms would not, and he was very sure that all the classrooms were the same size, how could this be?

Luo Yu walked back from the other side of the corridor, wanting to ask Yin Feng to see if he felt like this, and if he knew why it was like this.

Luo Yu subconsciously measured the length of the classroom with his footsteps as he walked, he took twenty-five steps from beginning to end in the first few classrooms, but after he walked twenty-four steps in the classroom on the very edge, he reached the end with a small half step, missing half a step?

Luo Yu returned to the door of classroom 707, stood at the door frame and glanced at the corridor, then at the classroom, and then suddenly realized, sure enough, the length of the corridor outside the wall was shorter than the length of the classroom.

Short corridors? Does that mean the wall at the end of the hallway is thicker? Or rather...... The wall they saw wasn't the wall of the original school building? Was the current wall newly built? So, what is the purpose of building this wall? To hide something? Is there something hidden behind the wall, or is it the original wall that is meant to be hidden? No wonder the sound he heard last night when he was nailing was strange, the wall was empty, and it naturally sounded different under the echo.

So, what's behind the wall?
