I held the letter paper and the photos tightly in my hands and stood there in a daze.

The sun was setting outside, and the sunset shone on the front hall of the old house. Suddenly, a gust of wind came, and my shirt, which was already wet with sweat, made me feel that my body was losing heat quickly.

"Zhou Cang, what did the professor say?" Seeing my ugly face, Wen Xiangyu asked in confusion.

My head was rumbling, and I couldn't answer her at all.

You are right, we are wrong...

This sentence and the father lying in the crystal coffin in the photo were like a huge dark cloud covering my mind.

Xiangyu walked up and asked tentatively, "Zhou Cang, can we read this letter?"

I raised my head, looked at the three classmates in front of me, thought for a while, and nodded.

After my permission, Wen Xiangyu took the letter paper and the photo over, and Zhang Jisheng and Chen Mo also walked over.

After just one look, Wen Xiangyu raised her head to look at me in a daze: "Zhou Cang, I don't understand."

"Why is the professor's letter irrelevant? What's wrong or not?" Zhang Jisheng said with a frown after reading the letter.

"But Zhou Cang obviously understood, and his face turned pale." Wen Xiangyu said, pointing to the photo again, "Why are the professor leaving such a photo? I feel so furious when I see it."

Wen Xiangyu said, looking at Chen Mo, probably hoping that he could also express some opinions, but Chen Mo remained silent after reading the letter.

The classmates didn’t know what I had in my grandfather’s study, so in their eyes, the content in the letter was inconsistent with the photos.

"Zhou Cang, what's going on with this photo?"

Perhaps because he realized that I had been unable to recover, Zhang Jisheng touched me and asked, "Do you understand? The professor's words were so vague. Is there any hidden truth?"

I knew they were expecting me to explain something, so they lowered their heads and thought for a while, and raised their heads, "The professor said, I didn't have hallucinations in the Zhuyin Ancient Temple by the beach back then."

"ah?"

As soon as I said this, my classmates were shocked.

"If you don't have hallucinations, is it because we have hallucinations?" Xiang Yu was the first to react, with an extremely surprised expression.

"The professor's meaning is probably that."

"But......"

Xiangyu only said half of what she said, and I probably know what she wanted to say later. Because she and her successor Chen Mo both participated in the beach sacrificial ceremony. If my experience was normal at the beginning, then what was their experience?

Zhang Jisheng looked at me in disbelief, "We experienced the incident back then together. Are you sure that the professor meant this?"

He said as he took off his glasses, almost put his face on the photo and looked at it carefully, then looked at the letter, "I still can't see that this photo and this letter have anything to do with what happened back then."

"photo,"

I hesitated for a moment and decided not to say it, "I didn't understand either."

After that, everyone fell into deep thought and my heart continued to be overturned.

Does the tomb under my grandfather's study exist? If it does not exist, then where did this photo come from?

"Children, the meal is ready,"

At this time, grandma came in.

After dinner, dark clouds rose in the sky, and the classmates also saw that I was not in a state, so they suggested that I rest early.

After returning to the room, I picked up the phone and sent a video to my father.

"Cang'er."

The video was connected. The father in the video was in a dormitory. The dormitory was built in a relatively simple manner and was obviously temporary.

Seeing my father appearing in front of me, I secretly let out a long breath, "Dad, are you doing your homework in the wild?"

"Yes, it's in Shanxi, a Han tomb."

Dad smiled, "You boy, why have you always looked for me these two days? Have you encountered anything?"

I didn't say anything.

"The fundamental decision of many things lies in what you think in your heart." Seeing that I had something to worry about, my father enlightened me. This is also his habit. When I have something to worry about, he never asks me what my thoughts are, but teaches me not to look at things with my eyes, but to look at them with my heart.

But this time my father's guidance made me suddenly think of the old man's strange words that day: This world is neither black nor white, nor is it true or false.

Could it be that my father knows what I have experienced recently?

I stared at my father in the video carefully, but the father in the video looked as usual.

I hesitated for a moment and decided to ask, "Dad, do you want to tell me something?"

"When you meet something, calm down and look at your heart."

My father's answer disappointed me a little. Obviously, he didn't know what I've experienced recently.

After hanging up the phone, I took out the photos in the letter and observed them carefully.

The photo was taken in a secret room. The secret room in my grandfather's study should indeed exist, otherwise the photo would not be explained.

After nightfall, I guess everyone was asleep and quietly walked into the study.

The clouds were thick tonight, the moon was completely covered, and the study was pitch black.

Worried that my grandfather was discovered, I didn't turn on the lights, and based on my memory of the study, I found my grandfather's desk.

Squatting down, I got under the desk, turned on the light source of my phone, and began to seriously study the two floor tiles under the desk.

The cement around the two floor tiles is still tightly fit, and the oldness of the cement in the caulking is not different from other parts around.

Could it be that the old man deliberately made the cement that was filled with the joints?

Thinking of this, I started to use my finger joints to knock on the two bricks.

The sound of returning disappointed me a little.

Under two bricks, there is a solid space.

I was worried that my ear would make a mistake, so I knocked it twice, and then knocked on the floor tiles in other places, and the sound I got was completely consistent.

Is there really no secret thought? I sighed, what happened to the professor's photo?

But at this moment, I heard a sound.

Deep, deep, deep, deep...

This sound is very similar to the memory in the secret passage.

But the sound was too thin and faint. I was not sure if it was my auditory hallucination, so I held my breath and listened attentively.

Finally, it was confirmed that the sound came from the attic in Grandpa’s study.

Is there anyone in the attic?

Thinking of this, I subconsciously took the light of my cell phone and shone it on the attic.

A pair of eyes were pressed against the gap between the attic wooden boards.

My pores exploded instantly, "Who?!"

Silent.

I quickly ran upstairs.

When I got upstairs, I took a photo of my cell phone everywhere, but there was no one in the attic.

Fear grew from the soles of my feet, and my breathing began to be rapid. The eyes that had just passed through the gaps in the floor were lingering in my mind.

I searched around the attic again, but I still couldn't find anyone.

But I was still unwilling to give up, so I searched carefully several times, but I still found nothing.

I sat tiredly on the stairs of the attic, feeling uneasy.

Suddenly a flash of lightning flashed across the night sky.

The entire study room was illuminated instantly.

"Tianfeng Guai."

Looking at the bookshelf that was flashing through the lightning, I blurted out these three words.

The old man’s bookshelf was actually arranged according to the Tianfeng Gua paintings of the sixty-four hexagrams of the Zhouyi.

The old man has always been superstitious about Zhou Yi. As long as his items are large, they will inevitably be placed in the form of hexagrams. I am no longer accustomed to this.

However, I have never noticed that the bookshelf in the study also became a hexagram. Although the lightning flashed just now, it clearly printed the order of the bookshelf in my mind like taking a photo, which made me see the hexagram of the bookshelf.

Slowly, I frowned.
Chapter completed!
