Looking up at the empty boat all year round, the glue grass coagulated the beginning of creation.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

It's a very long story to tell, and in fact its original cause may have been predestined in the gamma-ray burst that pierced the Genesis oceans hundreds of millions of years ago...... In the dual contradiction between preset genetic coding and adaptation to environmental evolution, the life form of this race is like being bound by two ropes pulled in different directions, and this tug-of-war process has lasted for hundreds of millions of years before calming down.

The people of the sea of the tide, or the sea giants, this ancient monster species that mixes the signs of land creatures and sea creatures, were not destroyed by the reverse tear under the favor of fate, but successfully continued in the ups and downs of several epochs of Lanxing, and finally, as seen today, they became this never-before-seen form: with a humanoid body, using the cheeks on both sides of the cheek to breathe, able to live in the deep sea but very dependent on visual observation of objects, and exoskeleton armor that provides strong body protection and power delivery assistance.

As a creature with both an exoskeleton and an endoskeleton, the Shiokai are born with an insect-like hydraulic power system and a rigid structure, which means that they have far more strength than their muscles, and although they can't compete with the hundred-meter-long behemoths, there are only a handful of species that can surpass the strength of the Shiokai people in a similar size. However, the biggest drawback of this exoskeleton armor is that it is too dense.

The heavy exoskeleton armor and the extremely dense muscular body are the characteristics of survival, but the Shiokai people have lost one of the most important abilities as sea creatures, that is, swimming. Their bodies are much denser than the water, so no matter how delicate they may swim, they can only sink to the bottom of the deep sea like solid pieces of iron, looking up at the creatures of the sea swimming back and forth above.

Is this lucky or unlucky? There may never be an answer to this question, but at least, just as the Moon Prayers aspire to be able to soar freely in the sky, so the Shiokai people also aspire to be able to swim freely in the ocean. In the most ancient times, they were one of the few creatures in the ocean that were limited by the terrain, and when faced with the undulating terrain of the submarine mountains, the hardships and hardships that the ancestors of the Shiokai people experienced are still unknown.

There are only two ways for the Shiokai people to be able to overlook the bottom of the sea from above. The first way is to find natural highlands, just like rock climbing on land, to challenge those rugged terrain, and the undercurrents that flow through you are like the wind blowing on land, and only the most persistent person can appreciate the beauty of seeing the mountains at a glance. The second way is to borrow the power of those creatures that can swim to reach the heights, but those who can swim with the Shiokai people must be behemoths, such as the giant sound decoy whales, these big guys are not so easy to get along with, even if the Shiokai people have a head-on confrontation with them, it is basically impossible to defeat the opponent.

This story went on for a long, long time, until the miracle called the Holy City appeared on that underwater plateau, and Shiokai discovered a third way to allow them to move freely in the ocean, and that was to use tools. The submersibles of the Holy City are a very complete means of transportation, but they are not allowed to be taken to the outside world except for special tasks, and they cannot be used privately. In the absence of an industrial base, it was obviously unrealistic to directly want to build these complex things, so the group of Holy City students who tried to help the development of the people of the outside world began to study simplified versions, even vehicles that could be made from raw materials in nature.

Like the people who first invented the airplane and wanted to take it to the skies, they were also full of a spirit of exploration, and the blueprint that lasted for many years was eventually given this name: the Artificial Empty Boat Project.

Like many great inventions, the initial beginnings were always full of ups and downs and setbacks, and it is said that when the artificial empty boat project was first started, these pioneers were ridiculed by others for their incompetence because of their poverty, and they would even be asked when they went out, "Yo, isn't this the kind of guy who wants to go to heaven?" "You are so powerful, why don't you go to heaven? "Your Excellency is so powerful, why don't you rise with the wind and soar to 90,000 miles? Words that sound malicious.

In this frustration-filled situation, the original man-made air boat project was launched. In the early myths of the Shiokai people, the empty boat was the name of the reef, and the man-made empty boat obviously could not simulate the seemingly rough but extremely precise structure of the reef. It is impossible to find light materials such as wood in the ocean to make empty boats, but fortunately there are enough ready-made theoretical knowledge to learn in the textbooks of the Holy City, including some of the principles of deep submersibles.

They eventually decided to adopt a principle similar to that of a deep submersible to control the sinking and floating, that is, to adjust the ascent and sinking by changing the amount of sea water inside the empty tank, a process that could be achieved by an ingenious pump, which was simply powered by a hand-cranked transmission...... After all, the arm strength of the people of the tide is very strong and can support it.

As for the movement of the front and back, the left and right can also be changed by using the propeller, if the hand or foot pedal to provide power output, even if the strength of one Xihai person is not enough, it can also be solved by multiple Xihai people through the linkage device.

All of this seems to be a good idea, but the most critical problem comes out, no matter how the internal water flow is changed, but the cabin that controls the sinking and floating must at least be sealed. Crafting a complex drivetrain requires a lot of hard, non-deformable parts that obviously can't be made of bone or stone. So the problem of materials became the biggest headache for the group of inventors, and they couldn't even light a fire in the ocean without being able to use the ready-made tools in the Holy City, let alone smelting metal, and how to seal it.

This problem has plagued the people of Shiokai for hundreds of years, and the original pioneers finally left only beautiful design blueprints, but they did not wait for the day of real success and passed away, until hundreds of years later, a Shiokai people who inherited the business of their ancestors discovered a rare plant called glue grass by chance. The plant has plump leaves, from which a strange-smelling, milky-white viscous liquid comes out of the leaves that do not dissolve in seawater, but rather clumps together in seawater.

Of course, if it is only to this extent, then this material is not unusual, the key is that this Xihai man found that this gelatinous substance will gradually harden under continuous high temperatures, becoming a special natural polymer compound, and the hardness is extremely high and not easy to deform, and it can also maintain its properties in seawater for a long time.

Because it is itself caused by the hardening and deformation of the gelatin, the material, named gum grin, is highly malleable and can even be used to process a wide variety of parts.

The mystery that has plagued the people of Xihai for countless years was solved, and suddenly this Xihai man named Xiwei became a well-known legend, and it didn't take long for him to get a promotion and a salary increase, become the general manager, become the CEO, marry Bai Fumei, and reach the peak of life......

However, even the heating equipment inside the Holy City was not allowed to be used to process the devices that had been taken out, so he had to find a way to heat the gum grease in the natural environment. I don't know if it's a coincidence or not, thirty kilometers to the south of the holy city is a large submarine hydrothermal vent area, theoretically calculated that the temperature of these large submarine hydrothermal vents is enough to make the gum grin completely solidify in the mold, but the relevant specific experiments are obviously essential.

After some preparations, Xiwei set off with a group of Shiokai people towards the area where the hot spring was located, and since this was an experimental work, they quickly reached the hot spring area using the deep submersible provided by the Holy City. It's easy to say, but the production process is actually a bit complicated...... They had to make rudimentary molds out of something similar to clay, hang them on slender bone sticks and burn them in the boiling waters of the hot springs, cut the leaves of the rubber grass they had brought, and stuff the grease into the molds while wearing makeshift gloves made of plant leaves. Gum resin is insoluble in seawater, and it is very dangerous for this faintly toxic substance to come into contact with the eyes or mouth, but it is too difficult to prevent this in an environment completely flooded with seawater.

Eventually, the Xihai man named Xiwei came up with an interesting solution, he boldly mixed a small pinch of sand grains into the gelatinous gum grease, which greatly enhanced the adsorption capacity of the materials to each other, making them more difficult to spread, and unexpectedly did not weaken the strength of the material, and even because of the composition of a composite similar pattern, the stability of the final product was greatly improved, which would undoubtedly be a big advantage for his future.

In the future, there are countless scholars who have speculated that this Xihai man named Xiwei may gain great wealth and status, and the discovery of gum grass grease solves not only the problem of man-made empty boats, but also a material that can be applied to countless aspects like iron on land, its value is immeasurable, even the gum itself, which was originally just a relatively rare plant, is instantly worth a hundred times, and has become a large-scale cash crop after countless years of cultivation.

However, perhaps fate is such an irony that as the inventor of all this, the Shiohai man named Xiwei did not enjoy all this in the end...... It was during the experiment of gum resin near the hot spring, presumably to observe more closely how the material changes at high temperatures, he boldly went a little deeper into the hot spring, and at that moment, a small earthquake broke out nearby, and a stream of boiling water directly penetrated the ground that was not solid under his feet, and swept him into the large hot sea under the sea in front of him. When the Shiokai people who were traveling with him risked their lives to pull him out of the hot spring, they found that he was already ...... Eight ripened.

Well, this is the story of a genius inventor who was tragically killed.
