Human vision.

It comes from the three types of cone cells and rod cells present in the eye. The cone cells sense strong light and color, and the rod cells are responsible for weak light and light and dark discrimination.

The light-sensitive artifact Huang Zu mentioned is actually the light-responsive protein in visual cells.

Once it senses light, it reacts immediately.

The three types of cones are most sensitive to three different bands of light, namely the three primary colors of the human eye: red, green and blue, allowing people to see all things in a colorful way.

However, divine objects that can sense light may not necessarily be suitable for making eyes. Some divine objects are particularly fond of light and respond to all colors of light.

Such a light-sensitive artifact can only sense the presence or absence of light.

For example, the root of Dinxia discovered by Huang Zu now.

Huang Ancestor got up and kicked him hard: "It's useless to break the stars, let the ancient ancestor show up in Bai, you are committing a heinous crime!"

He was so angry that he shed tears, fell to his knees and asked the sky.

"Guzu, excuse me!"

"Next time Huang Dingran finds a real light-sensitive artifact, he will never disappoint the ancient ancestor!"

Although he failed again, Huang Zu did not give up. His meaning was obvious, sorry to bother you, but I will dare next time!

The rivers and seas flow across, the oceans tilt, and the light breaks through the darkness in all directions.

Although the real light-sensitive god has not yet appeared, Guzhou has a faint expectation for Huang Zu. Although he is talkative and stupid, he is perseverant and pious enough.

Guzhou said: "Although this light-sensitive divine object cannot be used as the source of eyes, it has other wonderful uses. Haven't you noticed what changes have taken place after you lay down in this 'Root of Dinxia'?"
p>

Change...

Huang Zu scratched his head.

When you are independent, you are mature and self-reliant. Why do you always behave like a mindless child after your ancient ancestor appears?

So angry!

He racked his brains to recall, and suddenly an idea flashed through him.

"The ancient ancestor said that I should have been sleeping for a thousand years, but the roots of the dining cloud helped me wake up in advance. You are saying..."

The roots of the dining cloud are simple and green, like the broken cover of a wooden coffin floating in the sky. Huang Zu lowered his head blankly, and the strong roar of the oven of heaven and earth resounded through the sky.

He lifted up the oven of heaven and earth and separated it from the root of the dining cloud.

The roar stopped suddenly.

The high-power heaven and earth oven immediately shuts down and no longer produces the three-life magic medicine.

He lowered it so that it was in contact with the root of the meal.

Rumble——

The powerful roar like thunder sounded again, and the oven of heaven and earth roared at high frequency.

"..."

Huang Zu was stunned: "Why is this root of Xia Xia..."

The ancient ancestor's magnificent, compassionate and generous voice of wisdom suddenly sounded in his mind: "This root of Xixia has the essence of a chlorophyll analogue. Light can cause complex chemical reactions to occur, produce high-energy electrons, and convert light energy into electrical energy."

, establish an electrochemical electron gradient, and eventually become the source of energy for the heaven and earth oven to produce three kinds of magic medicine!"

Guzhou tried his best to explain it as plainly as possible: "To put it simply, with the root of Dinxia, ​​you can use light to drive the heaven and earth oven to produce a steady stream of three-life magic medicine!"

This is the principle of light reaction in plant photosynthesis.

That is to convert light energy into the chemical energy required by living organisms and store it.

"What!"

Huang Zu was so enlightened that he felt strange.

"If you plant flowers intentionally, they will not bloom, but if you plant willows unintentionally, they will create shade!"

"I was originally a breath-eater in the human world, and I have been struggling for thousands of years after ascending. Today, I! Huang! Will I finally transform again and become a cloud-eater?"

The oven of heaven and earth helps him survive by eating his breath.

The root of the dining glow protects the longevity of the dining glow!

He suddenly felt that this little hardship was nothing. With the Root of Dinxia, ​​he would be able to roam the sky forever, looking for light-sensitive artifacts for his ancient ancestors. He would never be tired or age again, which was a great thing.

Ah!

If the big bosses heard this, they would be moved to tears. Huang Zu is simply a born wage earner!

"Yellow..."

Guzhou sighed: "Light comes from outside the sky. It can be divided into day and night, and it can be divided into cloudy and sunny. Once night falls, the world will fall into boundless darkness. Even if you control the root of dining glow and the oven of heaven and earth, you will not be able to produce the three-life magic medicine.

You will sleep again!"

The world has day and night, and the sky is cloudy and sunny.

The cloudy sky and dark night made Huang Zu feel boundless panic: "Guzu, what should I do? I don't want to rest. I feel very uncomfortable if I stop for a minute and a second. All I can think about is struggle!!!"<

/p>

What a good wage earner!

Guzhou was deeply touched. With such a workaholic, why worry about the life of this star not being prosperous?

"The answer lies in wisdom, the future should be created by you yourself!"

Click!

Thunderbolt's lightning illuminated the sea surface with sparkling silver light, accompanied by a long-lasting sound of thunder.

Huang Zu covered his chest, and water oozed out excitedly: "That's it, Gu Zu, it turns out that you have given me the answer a long time ago, but I didn't understand it and didn't see the test you put on me!"

"I'm so stupid!"

"O ancient ancestor, please put your heart in your belly and watch!"

"Your grandson, the son of Lord Thunder and the Spirit Mother, the first ancestor of chaos, Huang! He will persevere and find the answer!"

Photosynthesis has light reactions and dark reactions.

The light reaction converts light energy into active chemical energy in ATP, which cannot be stored forever, but the dark reaction can fix the energy in organic sugars, store it for a long time, and use it as needed.

For Huang, this is the test of the ancient ancestor!

……

Huang Zu set out again, carrying the furnace of heaven and earth and the root of dining rosy clouds on his back.

He has gone through life and death tests again and again, but defeated them one by one. As the first life on this star, the living environment is undoubtedly very harsh. If Shen Jun had not injected genetic material into the planet, it would have been hundreds of millions of years before he would have had the chance to give birth to a child. Primitive cells.

The roaring lightning dragon, the roaring sea spray, the hot splashing magma, the entire planet is still in the midst of intense changes, but life is born as if it were the beginning of the world.

This is undoubtedly a huge disaster and test for life!

The night can be predicted, but the cloudy days are longer than the night. Even if he has mastered the root of the dining cloud, Huang Zu often falls into a deep sleep, sometimes for days, sometimes for years. At that time, old father Lei Gong seemed to have been stepped on. Roaring incessantly.

Huang Zu often used his brain to think about the laws of light appearance.

Nine thousand years ago.

For a thousand years, Huang Zu's cells struggled to compile a calendar of cloudy and sunny days and nights.

"The root of the glow can determine the presence or absence of light!"

"Twelve hours of daytime, twelve hours of night, and the cycle begins again and again. This is the law of nature!"

"However, old father Lei Gong often has an imbalance of yin and yang. When he is angry, the sky becomes cloudy, causing thunder and lightning, which is unpredictable."

He engraved the day and night watch on his body to form a new genetic chain, and developed the habit of roaming the sky during the day and sleeping peacefully at night. This habit lasted for thousands of years.

Wake up during the day and sleep at night.

As for the test of the ancient ancestor,

Huang Zu still had no clue. He often searched for genetic memories, but found nothing.

Where is the road?
