How did you, a prisoner on death row, become an important weapon of the country? Yecheng Gao Weiming

"Sister, what hint did your sixth sense give you?"

When Song Xiaocheng saw her sister's confused look, she was overjoyed.

Could it be that at the critical moment, my sister remembered the scene in her nightmare?

Everyone else thought so, with a look of anticipation on their faces.

Unfortunately, Song Xiaoxuan shook her head.

"No...nothing! Guys, I don't remember anything."

The expectation on everyone's faces disappeared, and despair began to envelope the entire room again.

"But...but it must be wrong! There must be something wrong..."

Song Xiaoxuan didn't bother to comfort everyone. She walked step by step to the iron gate and even touched the observation port with her hand.

"Su Ming, Lu Xiang, do you remember the question I just asked you?"

"So far, we have not found the key to the Plum Blossom 2 challenge. Which law of physics does it use..."

After these words were spoken, the people in the room were stunned again.

Yes!

It took a long time, about eighteen or nineteen minutes, and four calls were made.

Including Room B, it seems that there is no way out of the dilemma in all the rooms.

This is impossible!

Since Bell Labs had the audacity to hold this forum, it was intended to examine and test all challengers' mastery of physics.

Whether it is to screen talents or to achieve some BT purpose, there must always be a reason.

And the reason has everything to do with physics.

But what's going on now?

Six rooms to observe the number of lions and combine to complete the challenge together?

Simple addition?

Seems... unlikely!

"Xiaoxuan, what you mean is..."

Su Ming's eyes lit up, and he took a few steps towards the iron gate and said, "The organizer has been deliberately delaying time?"

"They set up two wired telephones and made complicated rules for us to pass messages to each other, with the ultimate purpose of misleading us?"

Song Xiaoxuan nodded slightly and stared at the hole in front of her.

“It should…it should be like this!”

"The iron door in Room A was already open, and anyone who entered would be attacked by a lion or a group of lions."

"If the organizers knew that Room A would lose connection, why did they do this?"

"The purpose behind this must be to mislead us and make us gain nothing in 30 minutes..."

"hiss!"

There was a sound of air-conditioning being sucked in, and everyone couldn't help but look up at the camera on the ceiling, feeling a deep chill.

Did the 2 of Clubs card intend to wipe out all challengers from the very beginning?

Do not!

If you want to kill someone, just kill him right away. Why go through so much trouble?

There must be a way to break the impasse, and it must involve knowledge of physics.

Once found, you will be able to break out of the predicament.

But we...

I can’t find it and I can’t think of it!

Everyone's eyes were focused on Song Xiaoxuan again, and no one dared to disturb her.

Because everyone found that this girl seemed to be in some strange state.

Reasoning state!

Her brain was working rapidly, and she seemed to have discovered something different.

really.

Song Xiaoxuan stroked the holes on the iron gate with her slender white fingers, still murmuring.

“Observe… observe…”

"This hole represents our eyes."

"But because of the size of the hole, we couldn't see the entire courtyard, so we had to rely on the view from other rooms."

"What if we install this hole, or this eye, into our body?"

"Then can we see... the scene of the entire courtyard..."

Following Song Xiaoxuan's words, the others also fell into a state of deep thought.

They were all top students, all academic masters, and everyone seemed to have gained some inspiration after listening to what he said.

But this revelation is too vague and illusory to grasp the key to the problem.

Especially Song Xiaocheng, who rolled his eyes when he heard that.

Although he doesn't understand, it doesn't stop him from complaining.

"Sister! Stop it! You're getting more and more ridiculous!"

"Can a hole in the iron gate become our eyes? Let us see the whole courtyard?"

"how is this possible?"

"I advise everyone to stop speculating! This is not a feudal society. It is not the rule that a gentleman should not talk about strange things. What! Do you want to ask the gods to possess you and make this hole really become our eyes?"

boom!

When Song Xiaocheng said this, everyone's heart exploded.

Especially Song Xiaoxuan, who was originally in a confused state, but her eyes suddenly became clear.

"Brother...Brother, what did you just say? Say it again?"

The girl turned around excitedly and looked at Song Xiaocheng intently.

Not only her, but also the eyes of the three boys Su Ming, Wang Luxiang and Zhang Lianhai were frighteningly bright.

Perhaps Anna was the only one who was still confused and couldn't understand their communication in Chinese.

Everyone seemed to have found the key to breaking the deadlock, but there seemed to be a layer of window paper blocking it, making it difficult to see clearly.

Song Xiaocheng was frightened by their looks and couldn't help but take a step back and scratch his head.

"what did I say?"

"I said, how can holes become our eyes!"

"This is not a feudal society. Confucius even said that he would not talk about strange things. Could it be that... could it be that we still need to ask the gods to possess us?"

boom!

When they heard Song Xiaocheng's words again, they felt as if thunder had exploded in their heads.

Correct!

Just the last four words!

Please God!

We need to pray to the gods to turn the holes in the iron gate into our eyes so that we can see the whole courtyard clearly, and even...

The current situation of Room A!

We seem to be able to clearly find out the number of all lion groups, allowing us to survive this challenge!

Several people showed ecstasy on their faces.

This left Song Xiaocheng still completely confused.

He looked at everyone in confusion, especially his sister Song Xiaoxuan.

"Girl! Don't... don't scare me!"

"What's wrong with you? I say, even if you can't count the total number of lions, you won't go crazy, right?"

"What, are you really going to ask the gods to possess you? Stop talking nonsense!"

"How can there be a God in this world?"

"I think we should start preparing honestly. When the iron gate opens, your brother will sacrifice his life to let you live..."

Listening to her brother's heartfelt words, Song Xiaoxuan felt a warm feeling in her heart.

But she no longer looked panic-stricken. Instead, she smiled and said two strange words.

"elder brother!"

"Do you know why our human eyes can see the world clearly? Do you know how cameras and video cameras work?"

amount……

Song Xiaocheng shook his head in confusion.

How the hell would I know!

Song Xiaoxuan did not answer her brother's question, but instead said the second strange sentence.

"Brother, do you believe it? Regardless of whether there are gods and ghosts in this world, physics can really help us summon gods!"

"Let this hole..."

Song Xiaoxuan turned around and pointed at the iron gate.

"Become the eyes of all of us!"

Song Xiaocheng's eyes widened when he heard this.

This……

How can it be?

He was about to question when he heard an excited shout from behind him.

"The light is as bright as the sun. The lower one is also high, and the higher one is also low..."

"The foot blocks the light below, so the scene is above; the head blocks the light above, so the scene is below. There is a limit to the distance and the light, so the scene is inside the storehouse!!!"

Song Xiaocheng turned around in confusion and saw Su Ming who looked crazy.

He just wanted to ask, Brother, what classical Chinese are you speaking at a time like this?

What? Do you want to show off before you die?

But who knows.

As Su Ming shouted excitedly, everyone's eyes became brighter.

Maybe Song Xiaocheng will never know.

Knowledge can really change your destiny.

This sentence comes from a book written by a man named Mozi more than 2,000 years ago:

【Mojing】.

The above sentence revealed the physics community's understanding of light more than a thousand years ahead of the West.

It is this sentence that reveals the principle why eyes can see the world and why cameras can record the world!

If we use four words to summarize what Mozi said, it would be...

Pinhole imaging!
