"Why is this? Although it cannot be said that every single-celled organism must have the 'eyespot' as a photosensitive organelle, it does not mean that all of them do not have it..."

Later, Hogu also noticed that in single-cell organisms, there are also no things like chloroplasts or chlorophyll that require 'light' to participate in reactions.

"Could it be that I was wrong from the beginning?"

"Is it possible that there is indeed no 'light' in the external environment, so these single-cell organisms have not evolved organelles related to 'light'."

From the situation of single-celled organisms, Hogu deduced such a conclusion.

There is a mutual influence between life and the environment. If there was no life from the beginning, the earth would gradually evolve into a barren planet.

The surrounding environment also determines the forms that organisms can develop and affects their evolution.

As an energy source like the sun, living things should be able to let go of anything. Even if there are no organelles related to 'light' at the beginning, they will find ways to evolve them.

However, Hogu was not in a hurry to draw conclusions. After thinking about it, he decided to continue several more large-scale captures of microorganisms.

"It would be too arbitrary to draw a conclusion just like this. This is just the first capture. Try it a few more times. If it still doesn't work, then you should be able to confirm that the location I am currently in is either the bottomless deep sea or the bottomless sea.

A dark underground lake without any light.”

The cell membrane and cell wall of non-living single-celled organisms are dismembered with trace amounts of enzymes, and then the internal organelles and gene fragments are pulled into the inner cells behind the surface cells of the cavity, and fixed on the inner wall of the cell membrane with connexins.

For a moment, Huo Gu actually had the illusion of getting rich overnight.

However, when he thought about the possible existence of multi-cellular organisms, his excitement quickly cooled down.

Huo Gu is very clear that although the current multi-cell colony is invincible against many microorganisms, once the opponent is replaced by a multi-cell organism, it will be as fragile as a newborn baby.

The cell wall that can block phages is thinner than paper in the eyes of macroscopic organisms.

Enzymes that can break down cell walls are harmless to macroscopic organisms.

The sharp teeth and claws of macroscopic organisms that can easily tear apart epidermal tissue, from the perspective of today's single-cell clusters, are equivalent to the nuclear weapons of those big countries seen by African indigenous people.

"It's not enough... There is still a long way to go before we are no longer threatened by life."

Huogu reminded himself of the current situation while instructing the cells to open their mouths.

In the eyes of microorganisms, the bloody mouth like a black hole slowly opened. Driven by the flow, Hogu's single-cell cluster pushed forward. Countless microorganisms and proteins, amino acids and other substances were just like this without being noticed.

Wrapped into the land of death.

Use enzymes to kill those viruses that are already worthless, extend the connecting proteins, capture a large number of microorganisms, dismember them, and carefully extract the genes and organelles of the microorganisms.

After two successes, he became more proficient the third time, opening and closing his mouth more times, and the instructions of Huogu and the cells in the cluster became more coordinated and no longer as mechanical as before.

After opening and closing hundreds of times, the opening and closing of the mouth seemed to Huo Gu to be no different from that of normal macroscopic organisms.

This is good news, but there is also bad news.

The cause of the matter was the single-celled organism with suspected mitochondria that Hogu had captured before. This single-celled organism was a sulfur bacterium that used sulfur to carry out life activities.

Hogu was no stranger to sulfur bacteria. He had seen such single-celled organisms using an electron microscope in the volcanic rocks he sampled.

This kind of creature is generally distributed in waters where sulfur exists. As their name suggests, they cannot live without sulfur.

Even in the original human period, sulfur bacteria were not extinct. They were mainly distributed near active volcanoes or hot springs and could survive even in boiling water of 100 degrees.

Since such a creature has been captured, it can be deduced that there must be a large area of ​​stable sulfur environment nearby.

"I just hope that place is not an active volcano."

Huo Gu was terrified, even though the volcano didn't erupt, it was just sending out thick smoke.

Bad substances mix with rainwater in the atmosphere along with smoke and dust. The result is either acid rain or alkali rain. After a heavy rain, the water quality environment will change drastically in an instant.

And those magma, without eyes to observe the surroundings, the magma is also extremely dangerous to Hogu and the single-cell cluster. The lava will make the surrounding liquid boil. In this high-temperature environment, the cells that combine into a whole

In a few seconds they will all be dead, or in other words, cooked.

There was no way, the current multicellular organism composed of single cells was too rudimentary, and it didn't even have a temperature sensing system. Hogu could only indirectly observe the water temperature through protein changes in the cell clusters.

If the fangs and claws of macroscopic organisms are equivalent to nuclear weapons at the level of great powers for today's single-cell clusters, then active volcanoes are equivalent to the sun. All Hogu can do now is to be in awe. Once the volcano erupts, he will use the cluster's current actions

Speed, it is certain to die.

"Only when you lose it can you know how precious those things are..."

Huogu missed his eyes very much, as well as the international civil aviation aircraft in the human world that could reach twice the speed of sound.

Clear away the distracting thoughts, there is not so much time for it to waste now, the threats hidden in the darkness will not wait for it to be ready.

There are two things that can be determined for now.

First, from the captured single-celled organisms, it can be determined that the surrounding environment is a completely dark environment, so no single-celled organism has evolved organelles related to 'light'.

Second, there is an unknown area nearby where sulfur is densely packed.

"Adhering to the worst-case scenario, assuming that there is such an active volcano nearby..."

Huogu's analysis came to an abrupt end, not because he didn't want to continue the deduction, but because his thinking was down.

In the face of absolute power, these are just futile struggles.

"...Sure enough, I still need eyes."

An idea appeared in Huo Gu's mind - since there is no organelle related to 'light', why not just create a pair of 'eyes' independently?

As soon as this thought appeared, it was like a wild weed, occupying Huogu's thoughts in an instant and unable to get rid of it no matter what.

"That's right, I can completely design a visual system by myself that is more sophisticated than the 'eyespots' of those single-celled organisms and has high performance."
