If it was just because he had some sense of belonging in his heart, Xin Yu would not have carried forward his fearless spirit and came to hold up a "sky" for his kind. Moreover, even if you add the more than 6,000 star magicians who are still in the ocean country, it seems to be a huge group, but in the face of this seemingly boundless tsunami tide, it is not easy to calm down.

At the very least, before the tsunami reached the eastern coast of the mainland, it would be absolutely impossible for Xingyu and them to suppress such a vast wave.

And Xin Yu himself also understands this, so after calculating the trajectory of the tsunami hurricane and the direction of the internal current, he roughly framed the section that can reach the coast of the ocean country and weaken these waves. Even so, Xin Yu was not sure that such a huge tsunami would be suppressed to a safe height in more than 20 hours...... That is, the height that the coastal breakwaters of maritime countries can withstand.

Speaking of which, Xin Yu actually wondered why there was such a tall wave in this world...... Even if it is a tsunami, it will not be so big and high, right? If you look at this tsunami as a huge wave, the number of waves Xin Yu has not yet counted, but the length of the edge of each wave is at least tens of thousands of kilometers, at least Xin Yu feels that the eastern coast of the entire continent is within the scope of this tsunami.

And, while it's impossible to count the number of waves that followed, the width of the waves, which stretches for thousands of miles, the so-called "wavelength" from crest to trough, is enough to be shocking. The height of the tsunami, which is the so-called "wave amplitude" from the crest to the trough, is also more than 200 meters high, which means that the wave height of this tsunami is at least 100 meters...... A wave height of 100 meters, if placed on the earth, can easily wipe out the entire planet of human beings.

Even if the continent of this world is extremely vast and relatively high in altitude, the entire coastal area of the continent, which extends at least 1,000 kilometers inward, will also suffer great disasters. Therefore, Xin Yu can't and can't care about whether other regions are affected by disasters, just saving the sea country is a difficult task.

Thanks to the tsunami on the periphery of the continent, Xin Yu was able to suppress the first wave within ten hours...... said that it was suppressed, but in fact, it only weakened the waves more than 100 meters high to only about 10 meters high.

Such a big wave, even on the earth, is not a disaster, but considering that the sea water in other places will be "transferred", Xin Yu has to set the "standard" so "low". If the tide continues to move towards the mainland, perhaps the height of the entire wave will increase to about 20 meters.

Although it seems that the wave levee of the maritime country is completely able to withstand such a high seawater "inflow", but because there is a difference between a tsunami and a wave after all, the reason why it is called a tsunami is because the speed of the waves, that is, the so-called wave speed, has reached more than 100 kilometers per hour.

Such a fast speed, coupled with the super high weight of the seawater, the kinetic energy contained in it is definitely very huge, Xin Yu is still a little worried about whether such a wave will destroy the wave protection of the Ocean Country. Although Xin Yu is very strict about the quality of such a "national shield", after all, the Ocean State has only been established for more than ten years, and the time to really start building this security line is only six or seven years.

Even if it was placed on the earth in the previous life, with the help of enough large construction machinery, it would be a staggering project to build such a tall and thick reinforced concrete embankment on thousands of kilometers of coastline. Not to mention seven years, it is seventy years, which is a bit incredible.

This is thanks to the fact that the Ocean Country is still a feudal dynasty, Xin Yu or the royal Xin family has absolute authority and can concentrate on doing great things, and because the wealth owned by the Ocean Country is more "excessive" for the whole country, so the first phase of the project can be completed in such a short time.

However, although the first safety line has been completed, the quality seems to be much more secure than it was in the past, when there were no levees. But Xin Yu knew that this safety line was definitely not enough to stop the tsunami.

Because in fact, the coastal defense embankment of the maritime country is not much better than the tofu slag project in the previous life...... It's not that anyone dares to cut corners, because Xin Yu has raised the quality problem to the height of punishment, and the lowest punishment is hanging, so it can be said that absolutely no one dares to risk their lives and be careless.

However, although the level of scientific and technological development of the Ocean Country is relatively high, it seems that it has reached the scientific and technological level of Xin Yu in the forties and fifties on the earth in his previous life, but it is just to solve the problem of "having and not", and in terms of quality, many things are still incomparable with that level.

For example, the quality of cement and steel bars, even if Xin Yu's golden finger guides the scientific and technological development of the Ocean Country, Xin Yu is not an all-round doctor after all. Even if he was relatively "hard" in his previous life, to be honest, he can't be omniscient, and it is already a very remarkable thing to be able to produce cement and steel.

You must know that even if a doctoral student with an orthodox education has the right major, it is impossible to develop the maritime country to this point on the basis of zero industry. What's more, Xingyu hadn't been to school for a day in his previous life, and it seemed that there were a lot of good level tutors who taught him knowledge, but that kind of education was no different from many "elite education" at all.

On the one hand, Xin Yu's own body in his previous life could not support him in what he did, so the content of the professor was all based on Xin Yu's preferences, not to mention the systematic, and the choice of content was also very arbitrary...... The purpose of Xin Yu's parents is just to let their son live a full life and be able to go through his life without regrets, can they still expect a person who may die at any time to achieve something?

On the other hand, Xin Yu's family is still different from ordinary people after all, even if you want to cultivate and operate, most of the education content you need to receive is some "high" knowledge such as social, etiquette and business strategies, and basic industrial technology things like cement and steel are basically "elective" items.

Xin Yu didn't have the knowledge of "elective" at the beginning, so in this world, Xin Yu could only make some inferences with more knowledge from physical chemistry textbooks. It was difficult for him to design a ball mill and a melting furnace, let alone produce high-grade cement and how strong the steel bar was.

So it seems that the wave embankment of the ocean country is very thick, but strictly speaking, it is really not a century-old project...... In fact, this is also where Xin Yu is dissatisfied with the ordinary merchants and researchers of the Ocean Country, and his subjective initiative is really poor, as if without the guidance of his prince, he can't even improve and upgrade the existing products...... This is still under the premise that Xin Yu has listed all the theories he knows as teaching materials, so it can be seen that Xin Yu originally wanted to use the diffusion technology to put pressure on the scientific research community of the maritime country, which is actually more necessary.

To get back to the point, it was precisely because Xin Yu was not confident in the quality of the building materials for the construction of the Haiphong embankment that Xin Yu decided to suppress the first wave of the tsunami within a radius of hundreds of kilometers to about ten meters, despite this, he was still worried that the low breakwater would not be able to stop such waves.

Of course, if Xin Yu was given time, with his and the help of more than 6,000 star magicians, he could completely quell the first wave of the tsunami, but he didn't have that time. As mentioned earlier, if it weren't for the scattered distribution of many sizes in the eastern part of the continent, which weakened the kinetic energy of this tsunami a little, and also blocked it for a period of time, Xin Yu would not even be able to suppress the first wave of the waves.

And after so-so broke up the first wave peak and pressed it, Xin Yu soon ushered in the second wave. Through calculations, we can also know that the wavelength of thousands of kilometers divided by the wave speed of hundreds of kilometers per hour can get the "frequency" of this tsunami, which is actually only a dozen hours.

For Xin Yu, because his mental strength is relatively large, and the total amount is not a few. Therefore, attacking for more than ten hours in a row is just a little fatigue for him. And most of the time, it is also because of the monotonous and boring work, which makes his heart tired, but the consumption of mental power is not particularly high.

After calming the first crest, Xin Yu was still able to hold on, but the other astrologists of the Ocean Country already had that kind of physical strength. This is also normal to say, because there is no foothold above the sea, and considering that the kinetic energy of the tsunami is relatively large after all, the speed is relatively fast. Therefore, the sorcerer must fly high above the tsunami waves, and also maintain the same direction and speed as the waves, plus he also needs to constantly attack and weaken the waves, so the huge consumption that lasts for a long time is not at all something that a low-level sorcerer can support.

Those astral magicians who have reached the realm of breaking the sky are okay, after all, the realm is there, and they can barely "suppress" the second peak, but those who are below the realm of breaking the sky, although they can barely fly in the air, but when they attack, they are mostly weak.

However, although the vast majority of the astral magicians in the Ocean Country were exhausted, they still did not stop what they were doing. First, Xin Yu, the leader, is still working hard, as subordinates, especially those who are accustomed to Xin Yu's leadership, they must continue when they don't get an order to stop...... This is the obedience that comes with militarized management.

This is because when these astral magicians joined the Ocean Country, they were just rookies of astromagicians who had just left the category of "ordinary people", so in their hearts, they did not have the "vices" of ordinary astromagicians, and felt that rescuing ordinary people was a redundant move.

In addition, when they joined the Ocean Country, the family and friends of these astral magicians were specially approved to immigrate to the Sea Country. In this way, whether in terms of sense of belonging or identity, they are all citizens of the maritime country, and it is still the unshirkable obligation of these "special soldiers" to fight for their own country.

This is also thanks to Xin Yu's ideological work done well, because these astrowizards have to be instilled with a sense of loyalty and national consciousness from time to time, so after joining the Ocean Country, coupled with the "bond" of the family, they have already regarded themselves as a part of the Ocean Country, so as to understand how important what they are doing now is to the Ocean Country.

So Xin Yu just encouraged: "Behind us is our home, for the safety of our families, even if we are tired, we have to continue." ”

It was precisely because of hearing Xin Yu's words that Li Gandui, who had been "ruthless and unjust", suddenly opened up and felt a kind of "warmth" that they had never felt, a sense of belonging to the team or the collective.

As a country, this sense of belonging is the foundation of maintaining the cohesion of the people, and for the team of astral magicians, this sense of belonging is the foundation for maintaining long-term development...... Although the sense of belonging that Li Qiandui and others realized had nothing to do with the maritime country, it was only the first time that they realized that they were also born as "human beings", and what they paid for ordinary people was not so "insignificant" or even unnecessary.

But with this beginning, it is possible to have a sense of belonging to the maritime country in the future, isn't it? Regardless of these miscellaneous things, the changes in the thinking of Li Qiandui and others have actually happened to Xin Yu.

I don't know if it's because of the influence of consciousness in my previous life, or if this world is too bizarre, which makes it difficult for Xin Yu to integrate into this world from the moment he was born in this world. In other words, Xin Yu actually doesn't have any sense of belonging to this world, as if playing a game, he always feels that he is dealing with a group of "NPCs...... Except for their own family members and wives.

However, this time of working hard for the ocean country, Xin Yu has also been sublimated in the ideological realm, not the kind of improvement in the cultivation realm, but only the sublimation of the moral realm...... Not to mention fighting for the safety of all mankind, at least Xin Yu is now working hard for the people of the Ocean Country. As Paul Kochagin said, "The most precious thing is life, and it gives us only once." A man's life should be spent in such a way that, when he looks back, he does not regret that he wasted his time, nor is he ashamed of his inaction, so that when he is dying, he can say: I have devoted my whole life and all my energies to the most magnificent cause in the world -- to fight for something and something in the world. ”
