“Don’t be afraid. The woman on the wall is not a ghost. It’s just a painting.”

“If you don’t believe me,” Chen Yu added, “you can go over and take a look for yourself.”

Hearing Chen Yu say that the woman on the wall was actually a painting, Hu Liang was dumbfounded.

“It really looks like a wall painting…”

Out of her trust in Chen Yu, Zhou Kexin mustered up her courage and carefully inched toward the wall.

She mumbled and reached out to touch the figure on the wall.

Hearing that, Hu Liang and Pan Yueling were emboldened.

They walked over and touched the wall painting.

A moment later, the two of them looked at each other.

It really was a wall painting.

“Dr. Chen, could this painting be made with some special technique that can be hidden on the wall?”

Zhou Kexin quickly figured out the problem that was happening in front of her.

The walls were bare and white.

There was clearly nothing there, yet a painting appeared when Chen Yu splashed the water on it.

She recalled a spy movie she had watched before that had a blank piece of white paper that could be smeared with some liquid to reveal the words.

“This painting on the wall is made of common paint. There’s nothing special about it,” Chen Yu said as he pointed at the wall ahead.

“What’s really interesting is the thing used to cover it.”

“What is it?”

Hu Liang asked.

“Lime powder.”

Chen Yu didn’t dawdle and revealed the answer.

There was nothing special about the paint used for the wall painting.

The reason people couldn’t see the painting was because the surface of the painting was smeared with a layer of lime powder solution.

“Once the lime powder solution has solidified, it will cover the painting.” “If lime powder meets water, it will produce a certain chemical reaction, revealing the painting.”

“After the water has dried, the walls will turn white again.”

“It will be covered by the solidified lime powder again, so the wall painting can’t be seen.”

“Mr. Hu, Ms. Pan,” Chen Yu said with a faint smile, “you two should know about the principles of optics, right?”

The two of them nodded in unison.

“This seemingly mysterious wall painting is a straightforward optical principle,” Chen Yu said.

“There are many gaps in the lime particles. Once the water molecules fill the gaps between the particles, the lime powder on the surface will be refracted.” “Light then can be refracted through the mixture of water and lime.”

“This way, the wall painting can also be clearly displayed.”

After saying this, Chen Yu glanced at Zhou Kexin, who was hesitating to speak. “The method of using lime powder to cover up a wall painting is similar to the method of keeping information confidential in spy movies.”

Zhou Kexin was shocked.

She was certain that not only could Chen Yu predict the future, but he could also read minds at the same time.

“Is this science or metaphysics?”

Pan Yueling asked her boyfriend, Hu Liang.

“It’s science, right?”

Hu Liang wasn’t sure.

The haunting of the old house started a few years after the poor girl’s death. According to the timeline, that was when the Qing Dynasty had just perished.

If Chen Yu wasn’t lying to them, then the lime powder concealing the wall painting was an optic principle.

Not only did this have to involve physics, but also chemical principles.

Late Qing Dynastry, Physics, Chemistry.

Why did the three words match so strangely?

“No, no, no. Haunted is haunted. It has nothing to do with science!”

“Think about it; did you often hear the cries of ghosts when you lived here?” Grandpa Jiang suddenly asked.

Hu Liang and Pan Yueling were a little scared again.

“Dr. Chen, if the female ghost we saw was actually this wall painting,”

“Then what about the ghost screams we heard?”

Hu Liang immediately explained in detail.

After hearing the strange sound, he and his girlfriend were only skeptical about whether it was haunted.

They had installed many surveillance cameras inside and outside the house.

When they heard the strange cry, there was no one nearby.

Hearing this, Chen Yu strode toward the potted plant on the ground nearby.

He took out a medium-sized pebble.

He went to the east wall and knocked on the wall with the pebble.

As the pebble knocked on the wall, a “dong” sound came from inside the wall.

“A hollow wall?!”

Hu Liang’s expression changed.

There would not be such a sound if it were a solid wall.

Pan Yueling could tell something was wrong with the sound coming from the wall.

She also picked up a pebble and knocked on the wall.

The wall was hollow from top to bottom, front to back.

“As you can see, this wall is actually a wall between two walls.”

Chen Yu bent down and reached out to grab the brick beneath the wall.

Chen Yu removed many bricks under the wall in the blink of an eye.

The gap created was enough for a person to crawl in.

Subsequently, Chen Yu bent over and crawled inside.

When he came out again, he had a mini speaker in his hand.

“The ghost screams you heard came from this Bluetooth speaker.”

Chen Yu tossed the mini speaker to Hu Liang.

The mini speaker was relatively new and looked like it had been bought not long ago.

Hu Liang and Pan Yueling were so angry that their lungs were about to explode.

It turned out that the strange sound came from this thing.

Grandpa Jiang looked at Chen Yu in shock. Soon after, an imperceptible strangeness flashed across his face.

Zhou Kexin caught a glimpse of Grandpa Jiang’s strange expression from the corner of her eye.

She looked at the mini speaker and the gap under the wall.

At this moment, Zhou Kexin had an idea and asked.

“Dr. Chen, there’s actually no ghost here at all, right? Someone is deliberately pretending to be a ghost to scare people.”

“I’ve said it before. No ghosts exist in this world, and no supernatural incidents have happened here.”

“This wall was built together with this old mansion. It’s used to protect lives and prevent bandits from burning, killing, and looting.”

Chen Yu wasn’t in a hurry to answer Zhou Kexin’s question. Instead, he unhurriedly explained the origin of the wall.

During the feudal era, wealthy families usually built life-saving mechanisms in their homes.

There were secret tunnels, walls, and secret doors.

There were many skilled craftsmen in ancient times. The secret tunnels and walls they built were difficult for ordinary people to discover.

“So, someone opened the wall and put a mini speaker inside.”

“No matter how many surveillance cameras you install, you won’t be able to find the truth.”

Hu Liang and Pan Yueling nodded heavily.

The two of them didn’t even think about it, let alone discover it.

“Grandpa Jiang, am I right?”

Chen Yu chuckled as he looked at the silent Grandpa Jiang.

Upon hearing this, Hu Liang and Zhou Kexin looked at Grandpa Jiang in unison.

Grandpa Jiang’s body trembled, and the muscles on his face quivered unnaturally.

“Grandpa Jiang, we have no grudges against each other. Why do you have to harm us like this?”

Hu Liang asked angrily.

If Grandpa Jiang did nothing wrong, why was his body trembling and expression so unnatural?

It was obviously a sign of guilt.

“Young man, don’t listen to his nonsense.”

“I’m just an old man. Why would I harm you?”

Grandpa Jiang defended himself without hesitation..
