Hoguta was embarrassed to find that the driving force formed by the flagella, which serve as 'plasma', did not seem to be enough to propel the cell clusters in which the number of cells increased dramatically.

"It seems necessary to redesign some things."

Concentrating his thinking, the three-dimensional structural diagram of cell clusters emerged in Huo Gu's thoughts.

So how should it be improved?

"Well... the main problem is still the driving force, maybe we should start from here."

"The driving force is insufficient, mainly because the flagellum is too short, which results in the forward force generated by the sliding water being insufficient to drive the entire cell cluster forward at high speed."

"So...for current cell clusters, flagella can only serve as a small drive engine for adjusting direction, and can no longer be the main source of power."

The question now is what kind of main driving engine should be installed for the cell cluster.

Hogu's mind pictured the spinal tail used by torpedoes, which combined with muscles to swing the water flow and provide a forward thrust.

However, Huo Gu gave up this idea.

The spine and tail of fish require spinal bones to be used. To redesign a skeletal system, there are too many issues to consider, such as water pressure, bone weight, etc.

And Hogu now needs to leave the dangerous area of ​​the volcano as soon as possible.

"Let's not think too much about the tail of the spine for the time being..."

Huogu's mind quickly flashed through the propulsion systems of marine life that had appeared in the history of the earth.

Forget about arthropods, their mobility mainly relies on climbing. Their only advantage is that they can be amphibious. Other than that, they have too many limitations.

Suddenly, while Huo Gu was wandering in his thoughts, an idea flashed through him.

"By the way, I can try the soft jet propulsion method."

The jet propulsion method, as the name suggests, is a process of inhaling water and discharging it.

In this process, sufficient kinetic energy is given to the water by the extrusion of muscle tissue. According to Newton's third law, 'the action force and reaction force between two objects are always on the same straight line at the same time, are equal in magnitude and opposite in direction',

With the help of the reaction force of the jet water, the displacement effect in the water is achieved.

The advantages and disadvantages of this method are obvious. The advantage is that it can reach a very high speed in a short time in the water. The disadvantage is that it is easy to lose the back force and does not have the longer-lasting propulsion ability of the spine and tail.

After all, when the water as the propulsion medium is exhausted, it needs to stop for replenishment.

Without further ado, Hogu immediately started working on improving cell clusters.

The jet propulsion method can be divided into three stages, namely the water inlet stage, the accumulation stage, and the injection stage.

As long as these three stages can be completed at one time, the jet propulsion engine will be declared complete.

The first step is to design a cavity that can hold the liquid.

This cavity cannot be too small, because the cavity is loaded with propulsion medium, which is directly related to the durability of the cell cluster's propulsion ability.

This was not difficult for Hogu, who could only understand cells. Soon, a new cavity was formed at the tail of the cylindrical creature.

Next comes the design of the water inlet. Hogu designed these openings at the head, so that with the help of the inertia of propulsion, water can be introduced into the cavity effortlessly.

For the water inlet, Hogu uses multiple water inlet valves to control the opening and closing through the mitochondria in the cells.

This is to ensure that water will not flow back out of the water inlet during the accumulation phase.

"The next step is the accumulation stage..."

With that said, Hogu focused his attention on a single cell, which needed to create a muscle cell template.

The biggest difference between muscle cells and other cells is that they can contract and contract very quickly. In addition, their fatigue resistance is also outstanding among cells.

However, Huogu did not intend to transform the muscle cells according to the memory.

The sophistication and complexity of those muscle cells far exceeds the energy required to create a set of bones.

Even when he first came into contact with muscle cells, Huo Gu couldn't help but start to wonder whether living organisms were natural products. If there was no interference from external forces, how could they have such exquisite and complex microstructures?

The precise structure of muscle cells is to correctly receive electrical signals from the brain, complete contractions at any time, and drive body activities.

However, Hogu can bypass this and can directly command the cells.

"Now that I think about it, I also have my own advantages. Maybe I can try combining mitochondria..."

The new type of cell to be produced is a cell with a simple structure and can simulate the contraction of muscle cells...

So, how to simulate muscle cells to achieve the effect of contraction.

Currently, Hogu possesses two types of mitochondria, one that processes sulfur and the other that processes hydrochloric acid to produce hypochlorous acid.

"Just follow the shape of muscle cells and divide them into multiple areas. The oxygen that is discharged from the cells will combine with hydrogen to form water. The muscle cells that have lost a lot of oxygen elements will inevitably shrink. In this way..."

The jet biological engine gradually became more sophisticated in Huo Gu's mind, and it continued to spit out and operate.

Then there is the injection stage. To achieve the injection effect and be able to spray for a long time, the injection valve needs to be small, but not too small, otherwise the output power will not be enough, and it must have a certain degree of relaxation.

Hogu continued to use muscle cells, so that the output power of the injection valve became controllable.

"I almost forgot, there is also a rudder."

When traveling at high speed, it is inevitable to encounter obstacles, so you must make flexible turns.

As a result, there were two pairs of 'small fans' on both sides of the three-dimensional model of the cell cluster in the Hogus Thought Sea. These small fans were called 'fins' in fish parlance.

By properly rotating the angle of the fin through muscle cells, you can achieve the effects of rapid climbing, settling, and turning in the water in a short period of time.

When the last cell returned to its position, the designed cell cluster drove the newly formed underwater engine. In the process of imparting kinetic energy to the water in the cavity, a curved arc can be clearly seen on the long cylindrical tail.

From a distance, it looks like a carefully carved porcelain bottle.

Bang!

Along with a sound wave using water as the medium, and a piece of volcanic ash being stirred up, Hogu's cell cluster disappeared from its original position.

"Fuck!"

It should be said that the designed underwater engine works very well, and the current speed of the cell cluster is completely beyond Huogu's expectations.

Desperately avoiding the jagged volcanic rocks at the bottom of the water, it felt like it was riding a rocket through the interstellar meteorite belt.

Every time, we avoid those rocks with narrowly missed chances, and it's only a matter of time before we hit those volcanic rocks.

Fortunately, this was not land, and Huo Gu had other options.

"Climb! Climb!"

Under the water flow guided by the fins, the cell clusters turned around urgently and climbed almost vertically upwards.
Chapter completed!
