Hoguta was embarrassed to find that the driving force formed by the flagella, which act as 'pulp', did not seem to be sufficient to propel the cluster of cells that had increased in number of cells.

"It seems that something needs to be redesigned."

Focusing on his thoughts, a three-dimensional structural diagram of the cell cluster surfaced in Hogu's thoughts.

So how can it be improved?

"Uh...... The main problem is still in the driving force, and perhaps we should start here. ”

"The driving force is insufficient, mainly because the flagella are too short, which results in the forward force generated by the sliding water is not enough to drive the entire cluster of cells forward at high speeds."

"So...... For today's clusters of cells, flagella can only be used as a small drive engine to adjust the direction, and can no longer be used as the main source of power. ”

The question now is what kind of main drive engine to install for the cell cluster.

Hogu's mind came to mind the spine tail used by the torpedo, which, through its combination with the muscles, swung the water current, providing a forward thrust.

However, Hogu dismissed this idea again.

The tail of the spine of fish requires spinal bones to be used, and there are too many issues to consider when redesigning a skeletal system, such as water pressure, bone weight, and so on.

Hogu now needs to get out of the dangerous part of the volcano as soon as possible.

"The tail of the spine won't think much about it for the time being......"

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

Arthropods forget it, their mobility is mainly by climbing, and the only advantage is that they can be amphibious, in addition, the limitations are too great.

Suddenly, Huo Gu was in the midst of a fugue in his thoughts.

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

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

In this process, the water is given enough kinetic energy by the extrusion of the muscle tissue, and according to Newton's third law, "the force and reaction force between two objects are always in the same straight line at the same time, equal in magnitude and opposite in direction", with the help of the reaction force of the jet of water, the displacement effect in the water is achieved.

The advantages and disadvantages of this method are obvious, the advantage is that it can be increased to a very high speed in a short period of time in the water, and the disadvantage is that it is easy to lose strength and does not have the more durable propulsion ability of the spine tail.

After all, when the water used as a medium of propulsion runs out, it needs to be stopped and recharged.

Without further ado, Hogu immediately began to work on the improvement of the cell cluster.

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

As long as all three stages can be completed at once, the jet propulsion engine is complete.

The first is to design a cavity that can hold liquids.

This cavity should not be too small, because the cavity is loaded with a propulsion medium, which is directly related to the persistence of the propulsion capacity of the cell cluster.

This was not a difficult task for Hogu, who was able to only cells, and soon, in the tail of the cylindrical creature, new cavities were formed.

This was followed by the design of the water intakes, which Hogu designed at the head, so that with the help of the inertia of propulsion, water could be easily introduced into the cavity.

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

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

"Next is the accumulation stage......

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

The biggest difference between muscle cells and other cells is that they shrink and contract quickly, and in addition, fatigue resistance is also outstanding among cells.

However, Hogu did not intend to modify the kind of muscle cells in his memory.

The sophistication of that muscle cell far exceeds the effort required to create a set of bones.

Even, when he first came into contact with muscle cells, Huo Gu couldn't help but wonder if the living body was a natural product, and if it wasn't for the interference of external forces, how could there be such a delicate and complex microscopic structure?

Muscle cells are precisely structured to receive electrical signals from the brain and contract at any given time, driving the body's activities.

However, Hogu can get around this, and it is able to command the cells directly.

"Now that I think about it, I also have my own advantages, maybe I can try to combine mitochondria......"

The new type of cell to be created is a cell with a simple structure that can mimic the contraction of muscle cells......

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

At present, Hogu has two types of mitochondria, one is for the processing of sulfur elements, and the other is for the processing of hydrochloric acid to make hypochlorous acid.

"The shape of the muscle cell is divided into multiple areas, and the oxygen that is expelled from the cell will combine with hydrogen to form water, and the muscle cell that has lost a lot of oxygen will inevitably shrink, so that it will ......."

The jet biological engine gradually became more refined in Hogu's sea of thought, and it continued to spew and operate.

Then there is the injection stage, in order to achieve the effect of spraying, and to be able to spray durably, the injection valve needs to be small, but not too small, otherwise the output power is not enough, and it must have a certain degree of relaxation.

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

"I almost forgot, and the rudder."

At high speeds, it is inevitable to encounter obstacles, which necessitates flexible turns.

As a result, on both sides of the three-dimensional model of the cell cluster in the Huogu Sihai Sea, there are two more pairs of 'small fans', and these small fans are called 'fins' by the name of fish.

Through the muscle cells, the appropriate angle of the fin can achieve the effect of rapid climbing, settling and turning in the water in a short time.

When the last cell is homeset, the designed cluster of cells drives the newly formed underwater engine, and in the process of imparting kinetic energy to the water in the cavity, a curved arc is clearly visible on the long cylindrical tail, which from a distance resembles an elaborately carved porcelain bottle.

Boom!

With a burst of sound waves mediated by water, and a cloud of volcanic ash that had been stirred up, the cluster of cells in Hogu vanished into its original location.

"it!"

The underwater engine designed by the company works so well that the speed at which the cell clusters are currently reaching is completely beyond Hogu's expectations.

Desperately dodging the rocky volcanic rocks underneath, it felt like it was on a rocket traveling through the interstellar meteorite belt.

Every time I narrowly avoided the rocks, it was only a matter of time before I hit the volcanic rocks.

Fortunately, this is not land, and Hogu has other options.

"Climb! Climb! ”

Under the fin-guided flow of water, the cell clusters make an emergency rudder and climb up almost vertically.

Behind him, the burst of water that swept out again seemed to be the final farewell.
