People are in Zhenguan, solving crimes scientifically

Chapter 8 Small hole imaging, basic science!

The four people present were immediately stunned by Lin Feng's words.

Even Han Keji felt dizzy and forgot to refute for a moment.

Sun Fujia was afraid that Lin Feng's words would anger Dai Zhou, so he hurriedly said: "Lin Feng, speak carefully. The mechanism you mentioned is right in front of us. What do you mean by turning a blind eye?"

Dai Zhou stared at Lin Feng closely, Xiao Yu held the teacup and forgot to drink it, and Han Keji subconsciously looked at Lin Feng.

Lin Feng smiled and said: "Before talking about this mechanism, I would like to ask Dai Shangshu to prepare a few things for me."

Dai Zhou said in a deep voice: "What is it?"

"A piece of harder paper, a candle."

"That's all?" Dai Zhou was surprised.

He knew that Lin Feng wanted something, which should be a mechanism to create ghosts, but he didn't expect that what Lin Feng wanted was so simple.

Lin Feng nodded: "That's all."

Dai Zhou took a deep look at Lin Feng and had no idea what Lin Feng was going to do. Han Keji also didn't know what tricks Lin Feng was going to play, and he didn't know how to object.

"Go and get ready." Dai Zhou said.

Soon, a piece of harder paper and a candle were delivered.

"What should we do next?" Dai Zhou asked.

Lin Feng smiled and said: "Please give Shangshu Dai some time and I will fold the paper."

"Origami?"

Every answer Lin Feng gave was beyond the expectations of those present.

Dai Zhou looked at Xiao Yu, who shook his head and said he didn't understand what Lin Feng was going to do.

He looked at Sun Fuga again and saw that Sun Fuga also had a blank expression on his face.

He subconsciously raised his head to look at Han Keji, but when he thought of Han Keji's disappointing performance, he stopped raising his head.

He was very relieved. Fortunately, no one knew about it, otherwise he would look too stupid.

"Fold it." Dai Zhou said.

Jailer Zhao Shiwu, who was tying up Lin Feng, quickly let go of Lin Feng. At the same time, he looked at his adoptive father with curiosity as he picked up the white paper and folded it.

Until now, Zhao Shiwu was still in a daze.

He never understood why Lin Feng, who originally cried and complained about injustice, became the person that both the Minister of Punishment and the Minister of Dali Temple looked forward to?

If my adoptive father really solved the mystery of ghosts and made a great contribution... Damn it, I wouldn't hold him in my arms, would I?

Zhao Shiwu became excited instantly.

Under everyone's nervous, hopeful, or malicious gazes, Lin Feng quickly folded the harder paper into a box.

Then he tore off one side of the box so that the inside of the box could be seen through this side.

After that, he poked a small hole in one side of the box.

After doing all this, Lin Feng said: "It's done."

"finished?"

The four of them looked at a box with one side missing on the table and a candle placed in front of the box with a small hole, their faces full of confusion.

At this time, even Sun Fujia couldn't help but said: "Lin Feng, is this...done?"

Lin Feng smiled and said: "How is it?"

Sun Fujia had no idea what this was for.

Han Keji was even more amused: "Lin Feng, don't tell me, you want to use this box and a candle to solve the mystery of the ghost?"

The iron ball in Dai Zhou's hand started spinning again, and he looked a little irritable: "Lin Feng, are you sure it's really completed? I have no intention of joking now."

Lin Feng knew that this was indeed difficult to understand for the ancients who lacked basic scientific knowledge.

He said: "Dai Gong Xiao Gong, don't be disappointed just now, you will understand soon."

With that said, Lin Feng picked up the fire stick and lit the candle.

Seeing this, Han Keji sneered directly: "Why don't you disappoint us? Lin Feng, look what you are doing. You just laughed at our agency for turning a blind eye, and then you came up with such a thing to fool us. Where is the official position?"

"Where did you put Dai Shangshu and Xiao Siqing? I think you are just stubborn and unworthy of death. You are - what!?"

Before he finished speaking, a 180-degree high-pitched sound suddenly came.

The shock made the tea in Xiao Yu's cup jump.

Lin Feng took out his ears. Can he sing dolphin sounds with this voice? "How can it be!?"

Han Keji's eyes almost popped out. He stared at the inside of the box and stood up in a flash.

His face suddenly turned red, and he wanted to say something, but he didn't want to.

"Have it! Have it!"

Sun Fujia's big face came directly close to the box. He stared at the scene in the box with wide eyes and clapped his hands subconsciously with excitement: "Dai Shangshu, Xiao Siqing, look, look quickly, the candle...the candle's flame, run away Into the box.”

When Dai Zhou and Xiao Yu heard this, they quickly stood up and took a look.

When they saw the inverted candlelight scene inside the box on the wall opposite the small hole, their pupils were shaken violently.

"The scene of the candlelight actually ran into the box!" Dai Zhou murmured.

Xiao Yu clenched his fist and suddenly raised his head: "I understand! So that's what it is, so that's what the ghost is like!"

"Haha, hahahaha!"

Dai Zhou also burst out laughing. He swung his bear paw and slapped Lin Feng on the shoulder: "I understand, Lin Feng, you have helped me a lot!"

"How could you come up with this method!"

Sun Fuga said: "Lin Feng, I knew I was right to trust you."

Han Keji looked at Lin Feng, who became the center of attention for a moment. His face was as blue as if he had eaten Sun Fujia's gift.

As for the reincarnation of Lu Bu, he was dumbfounded. He watched blankly as his adopted father suddenly became a hero praised by Dai Shangshu, and he felt a rush of blood rushing into his mind.

"I spent half my life wandering around, and finally met a good father. My adopted father! You will be my adopted father for the rest of my life!"

Lin Feng was slapped by Dai Zhou's bear paw and almost fell to his knees. He bared his teeth and cupped his hands and said with a smile: "Fortunately, I did not disgrace my life."

In fact, this is the most basic optical knowledge - pinhole imaging.

Lin Feng thought of this experiment when he saw the description of the scene in the file.

In order for the pinhole to be imaged, several conditions must be met.

The environment is dark, with small holes and light sources.

The palace of Princess Changle fully meets these conditions.

The environment, the princess wanted to sleep, so naturally all the nearby candles were extinguished.

So the palace is very dark.

Small holes... Most of the windows in ancient times were made of window paper. It is too easy to make small holes, just a bucket.

And the light source... was heavily guarded outside, with blazing torches and flames reaching into the sky.

All experiments for pinhole imaging are satisfied.

In this case, it really couldn't be easier to create a ghost.

You only need to practice it many times in advance, and then create a timed falling device outside the temple, and a ghost will naturally appear without anyone having to control it.

Dai Zhou was very satisfied with Lin Feng. He said: "You have done a good job. You have helped me a lot this time. If you want anything, as long as I can do it, I will satisfy you."

Lin Feng said directly: "I want to go to the scene to help Dai Shangshu solve the case and find out the culprit."

"Huh?" Dai Zhou raised his eyebrows: "You want to help me solve the case? What's the reason?"

He didn't believe that a death row prisoner had such a taste for selfless help.

Sun Fujia said: "Dai Shangshu, Lin Feng is willing to help us. In fact, he has a request... He wants to check the files on the Zhao Deshun case."

"Do you want to reverse the case?" Dai Zhou understood Lin Feng's appeal instantly, and his eyes suddenly sharpened: "You don't accept the verdict of this officer and Wei Gong?"

Lin Feng met Dai Zhou's sharp gaze and said calmly: "I want to die clearly...and the case is the least afraid of investigation, right? If there is no problem with the Zhao Deshun case, then it will be useless no matter how much I investigate."

When Han Keji heard that Lin Feng wanted to reverse the case, he hurriedly said: "Dai Shangshu, this is against the rules. He will be beheaded soon. He will definitely do anything to survive now. Don't be deceived by him."

Dai Zhou stared at Lin Feng for a long time. Lin Feng did not hide and looked at each other calmly.

"How brave! I really appreciate you."

Dai Zhou said calmly: "I am very satisfied with your performance. If you can really help me solve this case, what if I let you take a look at the files on the Zhao Deshun case?"

"I and Mr. Wei are not fools. Now that we have closed the case, we are sure...so I am not afraid of you checking the files. It is useless for you to check again."

Han Keji's expression froze.

Lin Feng was overjoyed and hurriedly bowed his hands: "Thank you, Dai Shangshu."
