The emergence of the 'breathing turbine gas turbine' can be regarded as a real change in agriculture, industry, military, transportation and many other aspects.

However, it is estimated that it is difficult to have flawless products in this world, and while taking into account the needs of one aspect, it may form a disadvantage in other aspects.

As far as the 'suction turbine gas engine' is concerned, almost all of its working processes must have the participation of totems, such as 'inhalation', 'air compression and pressurization', 'gas generation', 'mixed gas ignition' and so on in mechanical operation and chemical energy conversion;

Inside the machine, due to the extreme high temperature and high pressure working environment caused by the joint effect of totem and chemical and physical rules, each component will also have higher requirements in terms of working resistance;

This point, in addition to being overcome by the nature of the material itself, also depends on the support of totem inscriptions.

As a result, the 'turbine' will have a high material demand, a space requirement based on totemic inscriptions, a space requirement based on the corresponding nutrient reserves, and finally a technical requirement based on the difficulty of production.

When these requirements are combined, it leads to obvious shortcomings such as large installation space, high technical difficulty, and high material cost.

And in addition to this, there are some disadvantages that cannot be ignored...

First of all, due to the limitation of the operating principle, the power unit is only suitable for high-speed and stable operation scenarios, and the operation efficiency will be relatively low when idling or accelerating.

Secondly, its low-frequency noise does not cause real harm to trolls and elves with extremely sensitive hearing, but it is still psychologically unbearable;

Finally, the relative slow response time limits the use cases, such as urban commuting, which can be very clumsy.

As a result of these shortcomings, the universality of the turbine gas engine was insufficient, so Freya's second achievement, the piston gas engine, appeared when it was not just needed.

The working principle of the 'piston gas engine' is different from that of the turbine gas engine, which uses the full chemical energy to provide the driving force for the machinery;

In this process, the totemic effect only works in a very small number of aspects, such as 'gas generation and ignition', while the rest of the work is run by pure physical and chemical rules;

This can be done because the internal pressure is low, the temperature is low, and the properties of the material itself are enough to support the operation of the machine;

Therefore, the demand for totem inscription of the engine itself is not high, and the requirements for installed space are correspondingly reduced;

At the same time, it also has the advantages of large output torque and fast start because of its specific operating principle;

It is a kind of power output device with relatively small space requirements, relatively low material requirements, relatively low technical difficulty, relatively little manufacturing cost, and can better adapt to the characteristics of "small and medium-sized, medium and low-speed, frequent speed conversion" in the field of civil machinery power than the former, and has high application potential in Heyc City.

Of course, the disadvantages cannot be ignored, such as the power output efficiency problem caused by the low energy efficiency conversion of 'gas'......

However, the flaws are not concealed, and in general, it is still usable, especially after staggering the application scenario with the 'turbine gas engine', it can effectively fill many onshore power needs.

Like what.....

The environmental constraints of factories based on 'hydraulic applications' are no longer a rigid necessity, and almost any area can now exist as an industrial base.

'Crawler-propelled' and 'wheeled self-propelled' have become a reality, although they are not as powerful as arthropod feet in terms of terrain adaptability, but they also provide machines with faster travel speed 'under normal terrain';

As a result, the 'gas turbine' can play a powerful role in large-scale soil operations with its excellent power output;

The 'gas piston motor' can also play a corresponding function in the light relay transportation link of the highway by virtue of its sensitivity.

In addition, the position of moose in rail transportation will also usher in challenges, and in ultra-long-distance and long-distance reciprocating rail lines, the mechanically powered locomotive will have more use;

At its maximum speed, it may take several improvements to catch up with the moose herd, but its stability is better than the current moose pulling mode;

After all, moose herds are living creatures, and when urging them, they need to take into account their diet, rotation, emotions and many other things;

The power front is just a totem machine, in addition to the necessary maintenance, and nutrient supply preparation, there is no need to consider any 'humanistic care';

Therefore, the moose's position on the road within a certain mileage section may be replaced by the power of the front of the car.

In view of this, a simple judgment can be made -

In other words, the era of field work, construction site work, and transportation based on 'moose power' and 'giant power' will officially come to an end in the near future;

These two types of powerplants will further liberate the productive forces, thus allowing many producers to work more efficiently and have more spare time, and thus accelerate the process of elvenism of the republic and increase the average level of knowledge retention among the population.

Under the policy tilt of the ruling government, the deliberate attempts of the military, and the growth of the number of witch doctors, these above changes are accelerating in various scenarios....

On the river, the number of large transport ships driven by gas turbines and fishing boats driven by gas piston engines is gradually increasing from scratch.

In the offshore waters, giant battleships driven by steam turbines are being tested, and small and medium-sized air-to-sea attack ships and frigates based on steam turbines are also being designed.

In large publicly-owned farms, several specific models of testing machines are trying to carry out verification operations such as excavation and ploughing;

On the roads in the main city, several cars that look very simple are being verified on the closed road.

It seems that a larger scale of change is on the horizon.....

~~~~~~~~

With the maturity of airship technology, the headquarters has been much more rapid in the deployment of forces to the north, and one mainland base station after another has been established in a short period of time, and the scouts who have been sent to the north do not have to waste months of time on the way to their posts and on their way back to vacation.

The construction of the 'Aerospace Transport Route' has facilitated the delivery of front-line personnel, so that the headquarters can have more scouts searching for special magical beasts in the north, and the captives of the continental races and the characteristic magical beasts of the continent that were once inconvenient to be transported back also have the possibility of being transported alive.

The complex landforms of the north have nurtured many different civilizations and races, as well as various magical beasts with different abilities, so they have become living targets with great research value.

In December of the 65th year of the rune calendar, most of the northern continent was plunged into a cold winter, and a giant airship marked 'Exploration 23' was heading straight for the north from an altitude of 30,000 meters.

The central axis of the airbag above it is 350 meters long, the widest inner diameter is 90 meters, and it is filled with a large amount of stable inert light gas;

Driven by a rear turboprop engine, the airship is able to sail at speeds of 200 km/dh for more than several months with a large gondola underneath.

At an altitude of 30,000 meters, it is already in the stratosphere of the atmosphere, and very few life can survive in this harsh environment, so generally speaking, airships will not encounter major events other than mechanical failures.....

At the moment, there are 1 air attendant witch doctor, 3 war witch engineers, 15 escort fighters, and 40 intelligence officers, under the protection of specific totems such as life gas generation, riding airships to their respective destinations.

In addition, the non-crew compartment is also piled up with a full warehouse of mainland base station accessories, nutrients and other reserves;

The base stations that have been built on the ground will play the role of "road markers", remotely guide the airship to adjust its course, and become the transit destination for the corresponding passengers and equipment to be delivered.

Inside the airship, a witch doctor who accompanied the ship was assisted by totem equipment from beginning to end, monitoring the airspace conditions beyond his own observation limit;

In addition, 3 war witch engineers have also been paying attention to the operation of various totem components, preventing them from suddenly convulsing and crashing from a high altitude;

The 15 escort fighters also have their own tasks to be busy, such as the airbag armor and the activation of the quadripartite weapon system, which need to be controlled by them at their posts.

The 40 intelligence officers, who were supposed to rest before arriving at their destination, were gathering in the 'cabin' of the gondola with great interest to chat;

Most of them are spirited warriors, and the little ones are still in the form of trolls, and they are now mingling, talking about the new equipment they have received, and the strange civilizations in their respective regions;

On the whole, the atmosphere is very relaxed and harmonious, as if there is no difference in appearance and posture.

"If you want me to say, the Mengqi species should be the most powerful civilized race, the male is six meters tall and weighs more than 4 tons, and the female also has a height of about 5.5 meters and a weight of about 3 tons.

The one who spoke was an investigator who was specifically responsible for exploring the area of the Menglu Twin Kings Republic;

He was the closest to the work area, and he was also the first passenger to leave the empty boat, and at this time, while putting away his carry-on equipment, he was preaching the concept of 'big is beautiful, heavy is strong'.

The Mengqi species happened to grow up in his aesthetics, and in the course of the long mission, he couldn't help but envy their huge size.

In addition, he also felt that the mother was also quite seductive.....

Of course, this is not to say that he wants to rebel or anything, but like playing beast chess, he regards the Mengqi species as the best chess piece on his chessboard, and he can't help but take it out and compare it with his colleagues who are exploring the rest of the region, and compare their respective races;

And the mother is just a toning in the work, and his life is still trolls and elves, although the difference between these two is 'slightly' big.

Of course, not all of his colleagues agreed with him, and one of the elves retorted,

"What's the use of light weight, is that weak agility used as a live target? If you want me to say that the Yin species are the strongest, agile and powerful, majestic and not overbearing, what kind of long-nosed beast you are just food in front of them. ”

"Nonsense, you forgot about the war of slave emancipation three years ago? The 'most powerful' species in your mouth has been defeated, right? gave up three million slaves for no reason, hahaha~ This is the strongest in the hell. ”

Obviously, the affairs of the mainland cannot be hidden from the eyes of the republic, and because of the distance between the different regions where the continent tribes live, the specific situation in many regions, even the Black Forest, is more clearly understood.

"Hmph~ That's just that the Great Chief of Laiyin is too wasteful, he can't integrate those clan city-states under his command, otherwise it will be hellish if he can win the battle with that little bit of the beast."

"Haha, yes, right, if you were to be the chief of the Great Chieftain, you would definitely be able to defeat the two kings of Mengqiu, wouldn't you?"

"Of course.... Then I will tie up all my mothers and bring them back to the big tent, and give them joy and give birth to their children every day. ”

Some off-the-beaten-track topics stir up the nature of the males, but make some of the females frown....

'Smack! ’

So, the male elf who provoked the conversation received a serious slap on the back of the head, and when he looked back, he saw that it was the female warrior in the team....

"What? Do you want to give joy to the females and let them have children? Come to Celeusta, you will give me a joy? Let me also taste what it is like to have a baby? ”

In her hands was the beautiful female Elf Cynthiates, the most powerful of the forty scouts.

At this time, she was frowning slightly, looking directly at her colleague who had said the wrong thing, and there were still a few purple 'braids' at the intersection of the bottom of her head and neck, and she was also moving smartly in the envious eyes of the other elves and trolls, and some of the tips pointed to Celeusta who was slapped on the back of her head.

"Cynthia Boss, you misunderstood! They are females, you are females, and how can the female beasts of the barbarians compare with the female warriors of the Black Forest? I didn't mean that! You have to trust me!

”

"Hahaha~"

Hearing this, his colleagues laughed at him, and Cynthia was not really angry, so she sat back after giving him a hard look;

And her 'braids', which had been scattered before, also gathered into a whole strand at this time, and neatly burrowed into the hole of a rucksack on the side.

Seeing this, most of the other colleagues showed envy again.....

Among those present, whether elves or trolls, there are similar organs in the occipital bone of the back of the head;

However, most instances have organs the size of half a little finger, and are not as agile as the former, nor are they connected to any holes.

"Alas... This external plexus organ is too difficult to tame, and I've been implanted for more than half a year, but look, I still look half-dead. ”

One of the elves turned his head and motioned for his companions to look at the results of his workout......

I saw that the small 'braid' was like a dead thing, and it was not until half an hour later that it barely beat and was undetectable.

"Hey! It's not moving!

Let's see, it's moving!

！ ”

"Hahaha, don't make trouble~ It's still early for you, at least you have to be as flexible and flexible as me, and you can barely 'tame', as for the control of living armor? Ha! You just wait slowly~"

The other male warrior apparently had the same abilities as Cynthia, laughing as he showed off his long, nimble 'braids'.

"But, I really felt it just moved..."

The look on the detective's face was a little unwilling, but he didn't say anything more in the follow-up, but concentrated on the 'braids' to compete....

He has been envious of the powerful functionality of the external armor for a long time, but if you want to get the equipment, you must complete the pre-steps in advance...

While the scouts were laughing and talking, a terrible siren sounded, and then the familiar voice of the witch doctor who followed the ship came to the ears of all the passengers.

"Highest alert! Highest alert! Sightings of suspected large creatures! All hands are ready for battle, waiting for follow-up orders! It is expected that the eight lights will be faced directly, and it is expected that the eight lights will be faced directly! ”

~~~~

Earlier, the witch doctor Agathate was in the scouting room, receiving detection signals from all directions;

Suddenly, a distinct anomalous signal appeared in one direction, and this part of the vocal fluctuations was recognized, and then a large unnamed outline formed in her meditation space.

Judging from the fluctuations, this set of reflected signals, while molded, does seem to have some biological characteristics, and there are signs that it is approaching this direction.

This anomaly made Agatha puzzled and vigilant.....

She understands that if this thing is really a creature, then it will be a big problem for their group, because everything that can survive in this level is not an easy role.

Therefore, she immediately sounded the alarm as soon as she received the abnormal signal, but the boatload of expensive supplies made Agasha a little distressed, so she wanted to wait for the follow-up clearer results to come, and then go and decide on the next step.

After that, the whole boat entered a state of alert according to her order, and the soldiers in the armed control room turned on the totem armor of key parts such as airbags, hanging baskets, and engines, and controlled the wind wolf machine gun, airboat armor-piercing cannon and other weapons to start guarding.

Time passed in a calm atmosphere, and the sound reflections in Agatha's meditation space became clearer and clearer.....

After a programmed meditative calculation, the sound fluctuations gradually revealed their appearance in reality, and their actual size, flight speed, and other detailed data were expressed in the conversion.....

"Oh my God... What is this....."

Appearing in her meditation space was a sturdy flying creature with wings hanging from the sky, with a torso length of about 100 meters, a wingspan of more than 200 meters, sharp claws more than 10 meters long, and a rush speed of nearly 1,000 kilometers per lamp, all of which proved its formidable biological attributes.

"Damn it! Why am I so unlucky!

！ Agatha cursed in a frustrated whisper.....

The Republic's flight guidelines clearly stipulate that no matter how valuable the airship itself or its contents are, the lives of the passengers must be saved in the face of such a situation, so 'abandoning the ship and fleeing' is the only option at the moment;

So, enduring the heartache, Agatha issued a second command that was completely different from the previous one.....

"Confirm the target, it's a damn higher creature! All the fighters and scouts have it! Get the old lady into the life support cabin!

！ ”

"Engineers!

Set the full power self-operation mode of the armor and flight power components, and set the delay destruction procedure after ten minutes! Don't leave me with even the slightest remnant of technology! And then you guys go to the life support pod, too! ”

"Three lights! After three lights at the latest, the gondola escape pod will be separated from the main body and perform the airdrop mission! ”

Agatha's orders had kept the whole ship busy, and the threat of higher creatures was a must for all elves and trolls, so none of the passengers had expressed any objection at the moment, and they were all doing everything she had told.

After the two lights were divided, all the passengers, including the warriors, war witches, and scouts, except for Agatha herself, entered the escape pod with a strong cushioning force, and got into the individual survival pod, waiting for the moment of abandoning ship;

Halfway through the day, Agatha also arrived at her life support pod and confirmed that the airdrop had been performed.....

About half a light later, the escape section under the gondola separates from the main body of the gondola and the airbag above, and begins to move in free fall downward.

As for what exactly is the place below, then I won't consider the location for the time being, anyway, there is no danger of high-level demonic beasts coming......

~~~~~

At a height of 30,000 meters, the large airship that had lost all its crew and the gondola with only half of it was still moving forward rapidly, and everything seemed to be the same as before....

But at that moment, a huge winged creature flew like a sharp arrow, and the air formed a wall of air around it, and it was constantly bursting, followed by a 'boom' of air explosions.

It was impossible to tell what the giant bird looked like, and in the blink of an eye it had arrived from a distance of several kilometers beside the creature several times larger than itself;

After that, its flight trajectory changed abruptly, and the shadow of the giant bird crossed an arc along the airship at high speed, moving from the body facing the boat to its tail end, and then rushing straight forward without stopping.....

'Boom!

！ ’

A loud sound sounded in the next moment, and the armored power bay was powerless in front of its sharp beak, shattering in the air like a paper lake;

The gas that was constantly being generated and partially stored in advance exploded violently in the spark that rose in friction.

However, this level of explosion did not have the slightest effect on the giant bird, and after destroying the power compartment, it crashed through the airbag armor without stopping, and then broke through the airtight compartment all the way, and finally drilled out of the front of the airbag.

After that, it was not until it had rushed forward more than 1,000 meters under the action of inertia that the giant bird stopped its speed that had not been reduced since before, and slowly drew a graceful arc in the air, looking at the 'unknown creature' in front of it again.

Naturally, the airship could not afford to suffer such a toss, and at this time, a large stream of inert gas came out of the breach, making a not-so-strong air leakage sound in the air.

However, there was a little confusion and confusion in the eyes of the giant bird......
