In order to gain a foothold in the field of archaeology, it is not enough to specialize in biology, but also to expand the scope of knowledge to the field of geology.

Thanks to his previous knowledge, Hogu was not so passive in this strange place.

The purpose of including volcanic rock in the taproot is to analyze the general elemental proportions of the lava inside the volcano with the help of small rocks near the crater.

The use of coastal volcanic rocks is not due to the risk of analysis errors due to the fact that the seawater reacts with the rocks to a certain extent.

The rocks at the foot of the volcano were not used for the same reason, unlike the Cenozoic Earth's rainy environment, because of the volcanic ash, the rain of the Plutozoic is rich in various chemicals, and it rains heavily all the time on the volcanic rocks, and it is quite difficult to understand the original elemental proportions from these volcanic rocks.

What is the use of analyzing the elemental proportions of lava?

Knowing the elemental ratio, it is natural to deduce some of the properties of the lava in this volcano, such as volatile, viscosity and fluidity.

These properties determine the form in which the lava accumulated in the interior of the volcano will be released.

If it is rich in silica and volatile matter, the temperature of the lava is low, viscous, and the fluidity is poor, when the volcano erupts, it mainly releases energy in the form of explosions, which is very violent and violent, and will release a large amount of volcanic ash and volcanic bombs, which is quite dangerous, and if the energy is huge enough, it will even be accompanied by a certain degree of shock wave.

The magma contains low silica content, relatively little volatile, high temperature, low viscosity, and large magma fluidity, this lava volcanic eruption is relatively quiet, and will be similar to the overflow eruption of Hawaii volcanoes.

"That's why this island is relatively large, although I guessed it early on, I didn't think there was any need to be too surprised......"

"But the lava is much more fluid than expected, which is very gratifying."

The highly fluid lava, cooled and condensed into a large area of lava terraces and shield-shaped volcanoes, was skeptical when he first saw the appearance of this volcano, and now he finally got a definite answer from the information obtained.

"The high mobility means that even if the island is an active volcano, it is not impossible to use it, as long as it can be slightly remodeled......"

The thoughts gradually drifted away, summarizing the information transmitted by the two taproots, the three-dimensional projection of this volcano presents Huogu's thinking, although there is no information about the inside of the volcano, it can be inferred through the appearance, and it is not too difficult to accumulate Huogu's knowledge.

Caught in a long period of contemplation, this state lasted until another event pulled it back from its thoughts.

It took a lot of time to climb the mountain, and during that time, enough organic material had been collected, and Hogu knew it was time to start designing and creating a new variety of cell clusters.

Hogu has a habit of simplifying problems and then solving them quickly in a simple and efficient way.

Emptied all the chaotic thoughts in his thoughts, and recalled the various problems that the Hu individuals showed when they drove the Hu group, Huo Gu directly summarized it into a core - body type.

It is precisely because the body size is too small that it is so brittle and thin in terms of protection, and simply scratching the stone may cause fatal injuries.

If the body size is small, the weight-bearing capacity will naturally be small, and the number of sensory cells carrying it will be smaller, that is, the coverage area of the life field will be small.

Although the expansion of the coverage area of the life field can be realized through individual relay, there is an obvious delay in this method, which is unreliable in a complex and changeable environment.

"It's decided! Just design a sturdy and massive body, and use that super wave as an imaginary opponent......"

“…… At least once you have to endure it and still be unscathed! ”

A long vertebra came to mind.

If you want to design a large body, you first need to have a solid skeleton system to support the entire body, and a soft body design like a hoist without a little bone support is definitely not suitable.

If you really want to design it that way, it's a mass of soft meat that is difficult to move.

"Uh...... This is not good, this series of vertebrae is too heavy, and if you add heavy outer armor, it will have a great impact on speed......"

"In addition, it is necessary to have as much payload as possible and carry more sensory cells......"

The vertebrae in the mind are disrupted again, returning to square one, and at the same time, problems arise.

“…… Which skeleton design should I use? ”

Hogu asked himself, rethinking his countermeasures.

"Maybe ......"

A flash of inspiration suddenly occurred in Huogu's thoughts.

"If you need to consider the evolution of species, the spine is naturally the best choice, but I don't need to think about that, so I can go beyond the norm ......"

"In nature, where the main revolving revolves around 'who can live longer' rather than 'who has a better design', there have never been fewer examples in the history of the earth where species with well-developed and complex systems go extinct before species with rudimentary living systems."

After much deliberation, Hogu was finally willing to make a ruthless decision.

"Well, that's it, choose the design of the 'straight shell nautilus'."

An empty shell of a cone, which tended to be elongated, appeared in Hogu's mind.

Just like the straight-shelled nautilus, the interior is completely supported by a sturdy exoskeleton, although in terms of evolution, it is true that because of this exoskeleton, the evolution in the direction of large size is limited, and the straight-shell nautilus is because of this, in the Cambrian explosion of species race, went extinct.

But it doesn't matter, Hogu does not follow the route of natural selection evolution, there is no such limitation, and a strong exoskeleton is an advantage.

Especially with this conical design, the resistance in the water is minimized, just like a torpedo in the water.

Hogu would have thought of this design, also because he had just thought of torpedoes.

No matter how powerful the species is, in front of the tools made by humans, it is a joke, although there are indeed some creatures that can do things that human tools cannot do for the time being, but that is just an advantage that humans do not have the urgent desire of that aspect for the time being, and they are not in a hurry to make them, so they maintain an advantage for the time being.

As the fastest moving creature in the earth's oceans, the highest recorded speed is 190 kilometers per hour, which translates to a speed of about 100 knots.

And when Hogu was still on the earth, throwing away those torpedoes that countries were still secretly developing, even if it was the highest known torpedo, it could reach 100m/s, that is, the speed was about 200 knots!
