He began to observe as many cyanobacteria as he could, growing, aging, sick, and dying.

He soon discovered that the reason why cyanobacteria die so quickly is that there is no formed cell membrane, and they simply exchange substances with the external environment by their own tissue fluid, which has no resistance to harmful substances, and the efficiency of material exchange is also very low.

For example, when absorbing carbon dioxide and water vapor, it is easy to inhale toxic and harmful gases such as sulfur dioxide, and it is easy to be poisoned and burp on the spot.

Or when cyanobacteria are in direct contact with the soil, they are easily invaded by mud and other substances.

He thought about it for about half an hour before finally coming to a conclusion.

I need cell membranes!

Only the molded cell membrane structure can block external invasion and enhance the efficiency of nutrient absorption by forming more functional channels on the membrane.

He began to actively strengthen his spiritual connection to the small cyanobacteria community around him.

"Mould machine, start!"

Within a fraction of a second, this part of the cyanobacteria began to actively allocate the resources in the body, converging on the edges of the body, and trying to harden these resources to form a shell.

But in the blink of an eye, the coverage of cyanobacteria about the size of a palm around him instantly withered and yellowed, and the vitality quickly dissipated.

All dead.

Xu Zhifeng was stunned for a while.

Little brother, you died so miserably!

Five seconds of silence.

The surviving cyanobacteria community next to it spread again, and the yellowed area was quickly covered by the new cyanobacteria community, which was slightly lighter in color than before.

Start to learn from failures.

The reasons for the total extinction of this spore community when the hardened shell appeared just now can be summarized as follows.

First, too many nutrients are removed to sustain life.

Second, the hardened shell is completely closed to the outside world, cutting off the exchange of substances.

Thirdly, the hardened shell is deformed.

Fourth, the shell is damaged, which not only fails to protect and exchange materials, but also becomes a gap for air leakage.

I can't count how many billions of cyanobacteria there are in this piece, and anyway, all of them are wiped out to the point where there is no one left, which shows that his idea does not work.

He tried again with another cyanobacteria, and sure enough.

Changed again.

Extinguish again.

After ten attempts in a row, the conclusion is completely formed, this path is not working, and the probability is zero.

So what's the problem?

Xu Zhifeng began to recall his high school biology knowledge.

He suddenly remembered the rhizobia powder he had sprinkled when he planted Xuanling Grass, and suddenly realized.

Wait a minute!

I'm going in the wrong direction!

The cell membrane is not simply a accumulation of cell tissue, an important substance is missing in it!

Protein!

It is necessary to make the simplest single-celled organism, cyanobacteria, more complex and multifunctional, and to develop the function of synthesizing amino acids from nitrogen and protein from amino acids.

Then we can use protein as the basis to construct the cell membrane!

"Change your mind, I'm here for the protein!"

Xu Spore roared again, grabbing a handful of fertilizer bottles from the pillow side first.

Fertilizers contain ready-made proteins and amino acids.

He analyzes the structure of these things, not to produce them himself and then stuff them into the body of the cyanobacteria army, but to understand their structure first.

In this way, he can effectively manipulate the cyanobacteria to evolve in the direction of being able to synthesize proteins on their own.

He thought of a lot of ideas.

He first copied the protein in his own body, and then called on his own protein-like proteins in his body to compare them with them.

Then he used his deepened understanding to release part of the protein composition part of the ontological gene and introduce it into the cyanobacteria in the experimental field.

Three hours later, he didn't know how many times he had failed, and finally succeeded.

A small patch of multi-species cyanobacteria survives and multiplies rapidly.

The new cyanobacteria are slightly larger than the original cyanobacteria, survive longer, but divide more slowly.

Xu Zhifeng waited for about three or four hours, and was about to take the initiative to guide him by using the little time left before waking up, but he suddenly found that a new variety of refined new varieties had been born in that new cyanobacteria!

The new varieties have different shapes, some are long, some are cone-shaped, some are smaller in size, and some are several times larger than before.

The new varieties all have one thing in common, they all have cell membranes with different morphologies and functions.

To borrow a phrase from a biology teacher.

Biodiversity is beginning to emerge.

Xu Zhifeng didn't bother to pick the names one by one, and still regarded them as a cyanobacteria community in general.

New strains are gradually spreading far away in the competition with each other, and the canines are intertwined to expand their respective spheres of influence.

At the same time, the original basal cyanobacteria are also expanding in size, and there is no need to worry about being completely replaced by new dominant species.

The various colonies will form a wonderful balance.

Basal cyanobacteria are enriched with resources, rapidly expanding their range of influence, and leaving behind nutrients.

Each of the new colonies has its own strengths, whether it is longevity, or it is the size of the colony, or it may be the greater proliferative capacity that comes with a smaller size.

Of course, no matter what kind of bacteria it is, it will eventually die and become nutrients for the spore clones.

The day is almost dawn, and Xu Zhifeng's long sleep is coming to an end.

By this time, the land that had been changed color had spread to a radius of more than ten meters.

Today's farming work is almost complete, and the next step will be to continue to promote the evolution of cyanobacteria community, and strive to allow some dominant species to evolve ribosomes as soon as possible to form a more complete protein system, which can produce more types and more proteins.

This increases the average lifespan of new colonies and may even lead to the formation of nucleoids.

Single-celled organisms with nucleoids will have a stronger ability to proliferate, and the progeny will be more stable and reliable.

Jingle Bell Bell ......

The alarm goes off.

When he got up and went out, Chen Xi was putting things on the dining table in his pajamas.

Xu Zhifeng dazzled, and there were two bowls of meat and rice porridge!

He walked over and asked in disbelief, "Did you eat two bowls today?"

Chen Xi glanced at him, "A bowl of yours, do you like to eat it." ”

Xu Zhifeng sat down happily, "Wow, this is the attitude, it broke my diaphragm yesterday." ”

Chen Xi raised his foot and stepped on another chair with a big grin, pressed his right elbow on his knee, and shook his head full of messy hair: "Isn't it? brother, I'm also very uncomfortable! Alas, it's really a crime, what can I do in the future." ”

"Then I'll change classes, Teacher Han is not bad. ”

"Xiaofeng Peak...... Don't do that......"

"I'm Nima. I was wrong, wrong. ”

Xu Zhifeng trembled like a pendulum.

Outside, knowing that she was acting, although it was difficult, she could barely catch it, but at home, this lonely man and widow was in great contrast with her usual appearance, which was too distorted.

"By the way, let me ask you something, what is the background of this kid Hu Dingxing?"

Xu Zhifeng asked casually.

Chen Xi is sure that this matter is clear.

"Hu Yuanlang's son, I thought you were Wen Xingtong, but there are people you don't know. ”

Xu Zhifeng suddenly realized, "I remembered." ”

Chen Xi asked a little puzzled: "Didn't you reconcile, why did you ask him?"

Xu Zhifeng smiled, "Aren't I curious? By the way, otherwise you can just tell me what else Xuanshi is particular about." ”

Chen Xi pursed his lips disdainfully, "Don't say it, the feeling of hearing with your ears is completely different from seeing with your eyes, if it is really like what you said, then it will be clear that the carriage and horses will be written out on the Internet." I'll tell you now, it's a disservice to you. ”

"Okay, listen to you. ”

After breakfast, Chen Xi hurriedly went out again, she didn't have to go to school today, she could go to the mobile team to get some field expenses.

After she left, Xu Zhifeng slowly took out the little black book.

Hu Yuen-long, D.

Hu Dingxing, D.

The whole family of the Hu family, D?

Well, three D's.
