That person disappeared, and Ye Yang relaxed his grip on the sword hilt again.

Feng Ruoxing said in a low voice, "Should we go down and help Li Po?"

"Hold on, I want to see what he's up to." As Ye Yang spoke, the driver's voice came from the secret room again.

"You were brought back to your old classroom by a letter. The place where you used to have classes has been turned into a mourning hall."

"In the coffin in the mourning hall lies Qin Xin, the class beauty from back then."

"Qin Xin not only brought her own corpse back to the classroom but also left a letter."

"She wants to find her old deskmate, saying that she and her deskmate once shared a secret. A secret that can save all of you."

"She still remembers the secret but can't remember who her deskmate was?"

"What you have to do is first determine who her deskmate is."

As soon as the man's voice fell, the lights in the room came on. At this time, more than a dozen people were sitting in the classroom. As soon as the lights came on, more than a dozen bloodshot faces all looked at me.

As my gaze swept across their faces, the lights in the room went out again, and the man's voice rang out again: "Did you notice which desk had an empty seat, and which person had blood on their face?"

"Everyone's position will be switched after the lights come on. Find a seat and sit down. Believe the living, not the dead."

"Remember, not everyone who attends class in the classroom is alive."

When the lights in the classroom came on again, all the people who had been sitting in the room had indeed changed positions. The bloodstains on their faces were gone, and some even called us over.

"Li Po, come over here. We used to sit at the same table. You even copied my homework."

"Yuezhu, you're here? Come and sit down quickly. There's still a seat here."

Zhao Yuezhu said, "I remember there was no one in the corner by the wall. Let's go there!"

"Don't move! Let me think!" I reached out and grabbed Zhao Yuezhu.

There are no living people in this room!

The darkness in the secret room is deadly to ordinary people, but it's nothing to someone like me who has practiced pupil techniques.

I just clearly saw the people in the room exchange positions at a speed unimaginable to ordinary people. Moreover, I didn't hear any footsteps in the room.

With my level of cultivation, even if someone blindfolded me, I could still hear the sound of a Xiantian (Foundation Establishment) expert moving his feet within three meters.

When the secret room went dark just now, I couldn't even hear anyone breathing in the room.

The only possibility is that there is no one in the room anymore.

Feng Ruoxing, who was standing upstairs, also spoke at this time: "How come Li Po didn't see that the room is full of dead people?"

Ye Yang responded in a deep voice: "He saw it. The Zhan Ming Dao (Life Severing Blade) behind him is vibrating. Before Li Po draws his sword, there will be resonance between the man and the blade. That's why he can achieve man-blade unity every time."

I didn't know that Ye Yang and the others were watching me from upstairs. My gaze was still locked on the empty seats in the classroom.

Except for the four desks in the very back, against the two corners of the wall, the rest of the classroom only had one empty seat. When the lights came on just now, there was no one in those two positions.

It's the same now. The positions have been deliberately left empty.

I pushed Zhao Yuezhu and said, "You sit in the seat on the left side of the classroom, and I'll sit on the right side. Hurry!"

Zhao Yuezhu walked straight to the lower left corner of the classroom, while I walked towards the right side of the classroom, close to the coffin in front of the classroom.

As I passed the coffin, I gently knocked on it twice, and a sneer came from inside.

As soon as I stopped, I heard someone say, "Yuezhu, haven't you two forgotten to read the letter? Didn't the letter say that we should enter the door in the same way we did when we were in school? You entered wrong."

At this time, Zhao Yuezhu had already sat down in the corner of the classroom. The girl in front of her twisted her head and said to her, "Do you remember how we used to enter the classroom?"

"Xiao... Xiaowei!" Zhao Yuezhu's face turned a little pale, but her two hands clenched her backpack tightly. There must be something in her bag.

The girl who was talking to Zhao Yuezhu smiled sadly, "You finally remembered me. We were middle school classmates, have you forgotten?"

"When we entered the classroom in middle school, the two deskmates would enter together. After they entered and passed the first desk, the people behind could then enter."

"There's also a little secret about entering the door like this at school! Back then, after we accidentally learned this secret, we also kept a secret together!"

Zhao Yuezhu leaned back slightly, "What secret?"

Xiaowei's eyes became as hollow as her voice: "That is, there will never be an empty seat in the classroom. There are people in all the seats!"

"You're talking nonsense!" Zhao Yuezhu exclaimed, "Aren't the seats next to you all empty?"

"No!" Xiaowei's laughter became even more chilling: "The seats next to us are all full! You can't see people when you're standing, but you can see them after sitting for a while. Look, isn't there someone next to Li Po?"

Xiaowei turned her head to look at the door and said, "Huh! Who is this person? Li Po, who is the person you brought in?"
