The first thing to do to create a visual organ is to find a way to interact with light, which is called a 'photochemical reaction'.

The difficulty in making a visual organ is that it can accept light and convert it into a retina that understands biological waves, and it is precisely because of such an important component that the human eye can see the world.

"To carry out photoreaction activities, mitochondria need to be involved, so that the substance 'actinizes' from the ground state to the excited state, and then the excited state of the substance is introduced into the mitochondria for material processing, and the matter returns from the excited state to the ground state, one in and one out, which can form an electronic signal."

"And because light has different degrees of wavelength, there will be differences in the number of photons participating in photochemical reactions per unit time, and this can be used to paint an image of the outside world with electronic signals."

"Relying on these quickly drawn images to build continuity, like film in the eighties and nineties, forming a dynamic visual system."

With the deepening of self-exploration, the structure of the visual system in Huogu's thinking is gradually becoming clear.

Speaking of mitochondria, Hogu thought of the single-celled organism that had been captured and used sulfur for life reactions.

"The mitochondria that process sulfur can't meet my requirements......"

"Even if it is hypochlorous acid, photolysis requires ultraviolet ......."

"Wouldn't that be the only way to see the world from the ultraviolet perspective?"

Huo Gu thought for a moment and said.

"If you want to adjust the mitochondria, it is still necessary."

Time passed bit by bit, and Huo Gu didn't know how much time had passed, only that the cell cluster had been updated more than 400 times.

During this time, the number of cells did not increase much compared to the original, mainly for safety reasons.

In the case of the possible presence of active volcanoes in the vicinity, Hogu needs clusters of cells to ensure a base of mobility, excessive numbers at this time, just a burden.

Finally, the drawings of the visual system took shape in Hogu's mind, and the new mitochondria were designed.

This mitochondria mainly process hydrochloric acid, which binds carbon dioxide to convert hydrochlorous acid into hypochlorous acid.

After calming down, Hogu's attention began to concentrate highly.

During this time, it found that as long as its mind was highly focused on one thing, it could enter the state it was in when it was at war with bacteriophages, and its thinking would become very fast.

Of course, this comes at a cost, as the metabolism of cells will increase significantly and the average life expectancy will be shortened.

Hogu estimates that this is due to the accelerated process of energy release and reception by the cells.

Although he couldn't bear it, for the sake of overall safety, Hogu still had to do it.

The cells are dividing, they are being instructed to do so, and the whole group needs new members.

The cylindrical creatures floating in the liquid gradually open and close their mouths regularly, in order to obtain enough material to build the visual system they need.

Over time, a small bulge protruded from the side of the cylindrical creature, and gradually, over time, that small bulge grew into a thin column.

After some more time, the pillars ceased to elongate and became stout.

At the center of the column are a number of thin wires made of cells, which are the 'fiber optic cables' that carry retinal electrical signals.

These 'cables' are then wrapped around the inner cells that feed the nutrients.

Then, the outermost layer, the parietal cells that build a great wall to avoid the invasion of external viruses.

The column was the final preparation, and as the column grew, Hogu also collected enough chlorine to build the retina, which can receive ultraviolet light.

The parietal cells at the very end of the column begin to divide and grow into a sphere.

Then, in a safe place where the parietal cells are constructed, the inner cells transport the collected chlorine to the sphere.

Finally, the cells that are 'fiber optic cables' are also dividing, and they divide out some of the cells that transcribe DNA, the cytoplasm is acidic, and there are more mitochondria in the cell that can combine hypochlorous acid.

These are the retinal cells that Hogu prepares.

Half of the cells of the sphere gradually become transparent, like crystal clear glass, starting from the end, in order to be able to refract the collected light onto the retina.

The work of the parietal cells and the inner cells has not changed, they have only been adjusted by Hogu to adjust the pigments in the cytoplasm.

The moment the retina officially began to work, Hogu's perspective changed.

It has an extra perspective, and it is not abrupt, Huogu does not feel a sense of disobedience at all, it seems to be innate, it should be such a perspective.

This perspective can be said to be quite narrow compared to the perspective of comprehensive analysis of cell clusters.

The viewing angle can only see 180 degrees, and the other 180 degrees can see nothing.

However, Huo Gu didn't feel anything, and the problem of limited viewing angle could be easily solved, and he only needed to grow a visual system like this on the other side to achieve 360 degrees of observation without dead ends.

Hogu began to investigate his surroundings.

How to say that......

I don't know if I don't see it, and I'm shocked when I see it.

At some distance from Hogu, a huge column of smoke rose from the bottom and floated straight to the top, accompanied by countless bubbles, impurities, and other messes.

From time to time, Hogu could still see the root of the pillar of smoke, with a bright glow.

It's an active volcano underwater!

While Hogu was sad that he had guessed correctly, he was also feeling lucky.

If you don't have a vision system, you just take a chance and go with the flow in this area, and you may die in this active volcano at some point.

The ubiquitous flow can also be explained, and the active volcanoes underwater, which erupt at intervals, are not the eruptions of forces under the earth's crust, but the release of pressure caused by the blocked vents.

These small waves, when reflected off the surrounding rocks, form a turbulent current.

"Huh? Something is not right......"

"In this way, doesn't that mean that cells are only suitable for living in acidic liquids?!"

The pollution of water quality by active volcanoes is inevitable, and according to the previous microorganisms that use sulfur for their life activities, the liquids in this vicinity should be acidic.

In other words, since clusters of cells are able to hop around here, it means that they are actually organisms that live in an acidic environment.

Thinking of this, Huo Gu felt that his skull hurt, if he still had a skull.
