In the south, the volcanic complexes have turned into a yellow-green sea at this time ....

Vines transformed from roots are deeply embedded in the magma, ready to form a tight 'fishing net' under the pedestal, and take on the mission of isolating the upper and lower levels.

Some of them are brand new models, which are a little different from the old-timers that were planted before....

Strictly speaking, this new type of magic plant is actually a preliminary test of the 'plant armor' proposed earlier, or the kind that failed.

The reason why a failed product is a failed product must have one or another drawback.

In the case of the Witch Doctor, who has been tasked with the research of the 'Plant Armor', a mature product should have the ability to maintain its own activity and operate a totem when it is not grounded;

In addition, the mature product should be able to carry many totems in an acceptable size, and can be easily and accurately opened or closed by the warrior, and it is best to have the effect at any time by thinking about it....

However, most of these plans failed in the experimental products of this model, and the final totem bearing capacity was limited and the control mode was rigid, which was not suitable for application in actual combat.

But just as the witch doctor was about to abandon the plan with the research team and start a new path, an assistant asked a question..... Or an improvement plan.

He said

"Your Excellency the Witch Doctor, aren't you worried about the control of the plants on the volcanoes? Why not plant this thing as a tree and let the warriors control it? ”

"If you can go beyond the armor, then you don't have to worry about the size limitations caused by the power demand;"

"And once the size can be released, the totems they can carry will naturally increase;"

"At that time, even if there is still a rigidity in control, it should be able to play a role in restricting mobility, right?"

The idea was conceived by a non-spellcaster, and after the Republic increasingly popularized the concept of 'witch practitioners', such research-oriented non-spellcasters were given a new name—scholars.

Among them, some study physics, chemistry, mathematics and other natural subjects;

Others have devoted their energies to runics, spell-like natural perturbation, and totemism;

Others prefer to delve deeper into the law, music, naturalism, etc.

Although they have a qualitative gap in learning speed, memory, and brain computing ability compared to witch doctors;

But after all, a long life has generated a lot of time that can be used for learning, and those who have a heart always have the opportunity to make up for their own shortcomings in terms of knowledge.

Therefore, under the accumulation of time, their presence is not uncommon, and there are scholars in laboratories, research institutes, schools, law enforcement departments, law courts, and so on.

They are an important part of the scientific research and education forces of the Republic, and although they are mostly doing some basic work, they sometimes have a 'flash of inspiration' that has become an important impetus for the research of witch doctors.

This time, for example, the scholar's speech was listened to by the witch doctors, who began to make corresponding changes to the 'failed product'.....

As a result, the products that would have been abandoned were filled with new light, and they had the opportunity to shine in the present, and they became the 'new model of magic plants' mentioned at the beginning.

In the improvement plan, the seeds will be bred into saplings, and the inside of them will be built in the same way as the previous armor, together with the totem control system, to form the prototype of the 'cockpit';

As the sapling matures, the cockpit inside the trunk expands until it allows a warrior to manipulate its roots and crown through the Totem Hub to perform some of the tactical moves that were pre-programmed during the sapling phase.

Of course, it is in the same vein as the armor plan, which leads to this plan to avoid the 'amount of totem bearing', but also retain the disadvantages of 'rigid control' and 'need to be grounded to absorb nutrients'.

Therefore, it is impossible for the warrior in charge of control to control the tens of thousands of huge roots and branches;

They can only turn on or off the corresponding totem according to the timing, so that the magic plant they are in can complete the operation plan of several fixed modes.

For example, in order to achieve the transfer deployment, they need to recover part of the root system, transform it into an arthropod polypedal form, and transfer it to the farthest point of the residual grounded root system, and then decentralize part of the root system again and reclaim the grounded root system in the previous position.....

This cycle is carried out until it reaches the area where it needs to be deployed, and all the roots are lowered again to enter the pile output mode.

During this whole movement, the warriors can only turn on or off certain totems to allow the magic plants to complete the above actions on their own, and can only make a general control of the direction of movement.

Another example is to have the root system of other magic plants in the invisible magma layer find and merge with each other by automatically searching for other similar methods;

In this process, the warriors can only use the totem to carry out limited manipulation such as 'start', 'end', and 'key direction'.

Another example is to turn part of the crown into a vine to complete simple actions such as whipping, binding, lifting and pulling down.

But being able to do this is already considerable, and if nearly 10,000 plants can all be controlled in this way, even if it is just such a simple attack or restriction, it is enough to form a terrifying scale.

And will the Republic be able to mobilize nearly 10,000 fighters? In fact, yes....

New plants require the addition of cockpits, totem control centers, and other components, so they cannot be planted in the target area in a seeded state as before.

Therefore, they will go through many processes completed by breeding totem trees, giving birth to totem trees, and inscribed totem trees to become small saplings before they are pulled to their destinations.

All in all, when nearly 10,000 of these seedlings had been produced day and night, river transport ships transported them to the south in batches to be planted, and together with the old ones that had been planted, almost the entire highland was enveloped.

And when it comes to river transportation and boats, I have to mention another old friend......

The boat tooth that has not been seen for a long time... No, maybe we should call him Furnesta by pronunciation.

Furnesta was in his sixties, and he was much more mature and stable than he had been when he had committed the massacre in the tribe of Gabe.

During these years, except for individual practice, he devoted almost all his experience to the development of ships, and made indelible contributions to the development of shipping for the tribe and the Republic.

As a result, the Rune Council awarded him the distinction of 'Significant Contribution to Key Research Projects (Category 3) (Category 2)', and awarded him the Order of the River, 4th Class, in recognition of the Sweaty Moose of the Bunesta (Ship's Teeth) in the growth of the Clan.

~~~~~~

If we don't mention everything at the end of material acquisition, then the structure and operation of the ship is a complete natural physical process, and in fact, it is not easy to make a qualitative leap.

Therefore, in recent years, the Republic has also achieved remarkable results in shipping, with ships of various grades for different application scenarios, and categories of different levels of large and small tonnage, high and low speeds have emerged in an endless stream.

But in the end, it is only the same, in addition to the power of the oars or oars, in the loading and unloading of all the same labor, the function is nothing more than loading and transportation, on the whole there is no earth-shaking breakthrough.

Furnesta had thought of heading south, toward the other side of the sea, but even with a large ballista on his ship, he would not be able to deal with the troll-scaring beasts of the sea, which were thick-skinned and powerful, and often large.

Many attempts to go south to the sea, under the obstruction of the monsters, only went to the near sea and sank in the sand, coupled with the trolls' own characteristics of not being close to water, made the sea voyage a dangerous area;

And when the ocean exploration work suffered several heavy casualties, the Rune Council forcibly stopped this almost suicidal attempt, and specially issued a 'sea ban'....

The no-sea order states,

'Before there is a qualitative breakthrough in the technical level, those who go to sea without authorization, organize to go to sea, or instigate going to sea will be punished, and they will be severely punished; ’

'Whoever goes to sea without permission shall be punished with 1 to 3 years of compulsory labor in a closed manner; ’

'Whoever organizes or instigates one or more but not more than 10 trolls to go to sea together shall be sentenced to three days' dark confinement, one year's imprisonment, and 10 years' compulsory labor in a closed manner; ’

'Whoever organizes or instigates 10 or more but not more than 50 trolls to go to sea together shall be sentenced to 10 days of dark confinement, 3 years' imprisonment, and 30 years' closed compulsory labor; ’

'Whoever organizes or instigates 50 or more but less than 100 trolls to go to sea together shall be sentenced to 30 days of dark confinement, 10 years' imprisonment, and 60 years of closed compulsory labor; ’

'Whoever organizes or instigates more than 100 trolls to go to sea together shall be sentenced to 60 days of dark confinement, 30 years' imprisonment, and 120 years of closed forced labor; ’

'In the event of serious death or injury, the crime is increased by one degree, and the maximum penalty is the death penalty......

Furnesta can understand this, but the idea of exploring the sea is cold..... It wasn't until Nesta made a breakthrough and brought about a new technological revolution.

When Nesta led the witch doctors in the research and development and construction of the cannon and even the subsequent factory, Furnesta, as a senior witch doctor, naturally participated in it.

When it was, looking at the cannons of different calibers and the entire highly automated factory system, Furnesta had a strong seasonal movement;

He believes that such a thing as an air compressed cannon is simply a weapon of destiny born for the sea......

Ships floating in the sea are fully capable of carrying much larger calibers and more numbers of cannons than roadbed weapon systems;

In addition, the 'three-dimensional conformity enchantment' technology is also a tailor-made reinforcement scheme for giant ships, and ships with larger tonnage and stronger armor protection capabilities will be born with the support of this technology and become giant ships sailing on the ocean;

The automated factory model is the best production system that combines all of this efficiently....

Furnesta firmly believed that if this set of things could be transferred to shipbuilding, the ocean would no longer be an obstacle that had existed before the Republic, and the 'conquest of the sea' would be achieved in a short time.

Therefore, after completing his task in the cannon production system, he entered the process of formulating the Eucalyptus, and it only took a little more than a month to submit the feasibility report and the outlook for the results to the Rune Council for discretion.

When Nesta saw this report, his mind flashed back to the era of the giant ships and cannons of the previous life, and to the war monsters - 'battleships'.

He felt that this plan was quite feasible, and the larger-caliber naval guns would be transported to the giant ship in the mode of two and three loads, which would become a series of batteries floating in the ocean;

Even in the future war, the immediate operation against the higher salamanders will play a major role due to the fact that the volcanoes are close to the sea.

Now the only problem, that is, the power system, is that you can't still rely on wind and paddle power to drive, right?

Therefore, before the Rune Council entered the formal decision, he called the person in charge of the mechanical research institute that had arranged for the study of the steam engine to come closer, and after asking about the relevant information, he said that he would go to inspect it after the meeting.

And of course, the 'cannon on board plan' was adopted by the subsequent meeting;

The Rune Council instructed Furnesta to lead the study, and asked him to come up with a few usable 'galleys' as quickly as possible, even if they would fall apart after a few rounds of shelling;

As long as the lethality is enough and the quantity is enough, then where can the emergency be dealt with first....

After the meeting, Nesta went to the Institute of Mechanics, as he had said before.

The head of the Institute of Mechanics is a witch doctor, who is one of the inventors of many previous power machines, and his name is pronounced Masista.

The research on the steam engine led by him has actually lasted for a period of time, and has completed the development of the initial prototype and many subsequent improved models;

But because the power that these steam engines could bring was not even comparable to the power system applied to the armor-piercing self-propelled cannon, Matista did not see them as mature products, and continued his research.

But Nesta, who heard about its introduction just now, doesn't see it that way, and there are obviously models that can be used in the existing achievements, but this guy himself is too demanding.

Anyway, he decided to go and see it on the ground beforehand....

~~~~~

The new town is huge, and it is more or less a 'central city' with tens of thousands of inhabitants, so in order to make it easier to get around, the government has set up a rail system in the city, allowing moose to tow cars and run between the busiest fixed lines.

There was also a line between the Council Center and the Institute of Mechanics, and the two witch doctors boarded a rail tractor and set off for their destination with the sound of a 'cluck'.

There were other passengers in the car, but after bowing to Nesta, they did not bother the two gentlemen, who seemed to be busy, and paid attention to their own affairs;

Occasionally, those who need to get off the train at the station will not ask the car to stop, they often jump down directly with a salute, and then laugh and walk away;

The same is true for those who get into the car, the moment the tractor passes in front of them at a speed of nearly 70 km/h, they get up and use less than a second to rush into the car, and then grin proudly, throw the Black Forest coins into the coin box and find a place to sit;

Of course, there seems to be one more step today, and that is to salute Nesta in embarrassment.

Whenever this happens, Nesta just smiles and nods, and then continues the conversation with Masista;

He was basically asking about the institute, and Masista responded in detail.

From the witch doctor's mouth, Nesta learns a lot of information that she was not able to pay attention to;

Like what.....

There are already two witch doctors in the Institute, including Masista himself, and the two are comrades-in-arms who have been studying machinery together since their 'apprenticeship';

In addition, there are dozens of senior scholars in mechanical structure and physics in the institute, and half of them are also responsible for the teaching tasks of the central school;

In addition, there are dozens of graduating and senior trainee researchers from the first school of the Central Committee, the former is carrying out graduation internship tasks, and the latter is a professional student with targeted training;

In addition, occasionally there will be school teachers and children from the middle and lower grades to visit, and appropriately take them to do some interesting or novel experiments in the institute to deepen their interest in learning.

And these are basically the 'cooperation' reached by the education department of the ruling government in the middle....

Nesta listened to the news with great pleasure, sometimes nodding and sometimes opening his mouth to study;

I don't know why, his mood at this time is even happier than when he broke through the previous ranks.

It was in the midst of such conversations that the new site of the Institute of Mechanical Research was approaching.....

~~~~~~

It is located in the new town, but it is generally quite remote, and there are a number of research institutes in the vicinity that could not be relocated to the mother tree due to site requirements, and the Mechanical Research Institute is one of them.

The Mechanical Research Institute is surrounded by a large courtyard wall, and the largest building within it can be seen from the center of the new town.

It is a large research building with a length of 80 meters, a width of 60 meters, and a height of 90 meters, with a total of six floors.

Although it looks very similar to Nesta's previous building, Masista knows that this is not the case, this building is actually a combination of three multi-purpose treehouses, and its interior has a lot of totem hubs that are easy for non-casters to control, which can be used as a good aid in research.

The moment the tractor approached the institute, the two witch doctors jumped out of the car to a kind of troll cheer, and then waved to the car that had flown out a long way in the blink of an eye, and turned around and walked towards the large courtyard with less than two hundred meters left.

At the entrance of the research institute, the soldiers belonging to the internal security department of the Military Commission were responsible for standing guard, and after seeing Nesta at this time, he took the lead in saluting, and after exercising the verification link, he manipulated the totem to open the door.

Nesta returned to the guard salute before entering the compound with Massista towards the research building.

At this point, Masista began his introduction again, pointing to the other buildings that were a little lower, or open space, and stating their functions.

Among them, there are sports fields, canteens, indoor parking lots, and specially built high-temperature and high-pressure flame bathhouses, which are all areas related to life.

In addition, there is a material test field for the cultivation of special plants, which is one of the important branches of the Mechanical Research Institute.

Outside the building, there are several large booms that connect the sixth floor to the first floor, which are designed to handle large machinery.

In the building, there are several high-speed plant 'elevator rooms' in the south, east and west, which can easily access all the locations in the front building;

That's right, it's not a straight up and down commute between floors, but a direct drill through the walls under the control of the totem, and follow the prescribed route to the office.

In addition, if the communication is completed in advance, then the whole relocation can be carried out as large as a floor or as small as an office....

For example, today's first floor can be tomorrow's sixth floor;

For another example, room 301 today can be room 401 tomorrow;

Another example is the merger of the third and fourth floors, which makes the entire research east one floor less out of thin air, and so on.....

This design is not 'interesting', but because there are many large machines in the mechanical research institute that are difficult to move up and down, and they need to be assisted by this means.

Hearing this, the two Nestas entered the building, boarded the 'direct elevator', and went straight to the storage site of the experimental steam power formations of the past.

So, Nesta started the tour with the introduction of Masista.

From the toy-like steam runner, to the steam condensation vacuum power machine, to the expansion water cooling power machine, and to the application of high-pressure boilers....

Because the properties of the materials far exceeded the upper limits of the application of existing technology, and the precocious maturity of physical theories supported by magic, Nesta saw a rapidly advancing steam power system.

The latest mature product of the institute is a three-cylinder re-expansion steam power system, which uses the internal energy of steam to use the internal energy of the steam more efficiently through the high-pressure, medium-pressure and low-pressure cylinders arranged from small to large, and drives the external shaft to form power.

It has a quite complex transmission structure inside, and there is also a very precise operation logic between many pistons and connecting rods, forming a relatively efficient internal energy conversion and power transmission system.

At this time, some non-caster researchers are making improvements to this relatively mature plan, such as optimizing its mechanical structure, trying to add a totem control system, and so on.

But more researchers have shifted to the early stages of the new idea, led by Masista......

Masta said with some trepidation,

"Your Excellency, I believe that the gas compression reactor is also very promising in terms of power, so I have started the preliminary design of this aspect..... But I'm not in any way diverting the budget for the study, it's still in the paper design stage, and I was going to complete the feasibility study before submitting it to you. ”

Nesta looked at the researchers who had risen to greet him as he arrived, and saw that their desks were indeed full of pens and paper for calculations, and that there were temporary small modules on the walls, so she nodded noncommittally and asked what Masista meant by a 'new idea'.

Speaking of this, the witch doctor was full of enthusiasm and detailed to introduce Nesta's idea...

Masista proposed that the current idea of using steam expansion to drive the movement of the piston be replaced with the use of air compression reactor to do the work of the blasting process.

He took out a drawing on which two parallel arrangements of 'cannons' were drawn with sphere reactors;

At the upper end of the reactor chamber, where the gun barrels were originally placed, two pipes with suction functions were arranged and connected to the piston box above;

The connecting rods at the upper end of the two pistons are connected to the complex transmission structure.

He explains,

"When the reaction chamber is deflated, the upper piston is driven to move upward, and when the air is compressed and suctioned, a low-pressure area appears at the lower end of the piston box, so that the piston moves downward;"

"The force generated by these two processes can be formed by the reciprocating motion of the connecting rod above the piston in the transmission section, which can form a dynamic force."

"The problem at this stage is that the violent activity of the reactor chamber is too violent, and without venting like the cannon, it will exert tremendous pressure on the piston box;"

"In addition, the compression time required for a large reactor is too long, and although the kinetic energy generated during the explosion is quite large, on the one hand, it is more difficult to use because of the above reasons, and on the other hand, there is also the disadvantage that the work interval is too long and cannot form a long-term power."

"Therefore, I think that when applying it to the power system, the gas output power of the reactor is not as strong as possible, but it is necessary to use an appropriate small reactor for multiple groups in parallel, so as to reduce the difficulty of utilization and reduce the work interval."

"This type of power generation has great advantages over existing steam power;"

"On the one hand, it can reduce the reserved space for fuel bunkers and water storage in the machinery, and the reserve of shells and other materials can be increased accordingly;"

"On the other hand, the energy efficiency ratio is much higher than that of charcoal, and it also exceeds the efficiency of directly converting the internal energy of the plant into kinetic energy (the plant itself drives the wheels, propellers, arthropods, etc.), but it is ....."

"It's just that you need Cave Wolf Cell Fluid, right?"

"Uh.... Yes, you know ..... But if it's a surface ship, the existing complex nutrients can actually make do...."

"It's just that the amount of nutrients needed for the same voyage may be increased several times..."

"How does it compare to charcoal and water reserves?"

"The calculation has not yet reached that point, but judging from the existing data, it still has an absolute advantage in terms of space and weight."

"Hmm.... I understand, so let's go ahead and submit it to the Rune Council for review when the time comes. ”

"Understood!"

“..... In this way, the battleship project is something that has been approved and needs to be produced as soon as possible, and the Mechanical Research Institute first contacted Furnesta to work together to get the application of the multi-cylinder rebloated steam engine on the battleship; ”

"But that thing..."

"Don't worry, it's enough as a substitute in the short term."

"Okay... I understand. ”

"Okay.... By the way, of course, you have a bottom of many parameter requirements for ship power in this process, and then you will submit your current idea as a more advanced power take-off device for review. ”

"Yes, Your Excellency, I see!"

"Besides, I have an idea here that you can take and ponder ......"

"Speak, please."

"I'm thinking, the kind you just had... Let's call it an 'airburst reciprocating engine', it seems that this thing will lose some of its energy at the conversion end, right? ”

"Yes, the mechanics are not very advanced, and they are not substantially different from the steam engine."

"Can we do away with the intermediate piston and so on, and directly apply the impact force caused by the air burst to the spindle?"

"What do you mean?" Marcista asked uncertainly.

"When you studied the tail of the artillery shell before, you have read all the data that came with it, right?"

"Yes, Your Excellency...."

"What to say..."

Nesta thought about it for a long time, but couldn't figure out how to describe what she wanted to express;

But this doesn't stop him, and if he can't tell, then make one on the spot and show them.....

So, while complaining that the language system is still not rich enough, he began to do it directly.

Nesta's 'Dove Occupies the Magpie's Nest' and backhands take control of the ground in front of him, and begins to deform it with a spell;

As a result of his adjustments, a cube protrudes from the surface and gradually begins to evolve in the direction Nesta wants, eventually forming a separate mechanical structure from the ground.

Nesta placed the complex machine, about a meter or so, on the table and pointed to the side that had been specially made into a semi-open structure, and began to explain his thoughts.

"You see, the high-pressure air is coming in from here,,,," he said, pointing to the opening in the center of the front end of the machine.

"The incoming air flow will first pass through these fan blades with a curvature.... Let's call it a 'power turbine'...."

He was referring to the front row of the fans arranged in a circle on the main shaft, like shutters.

"The second layer is also a similar dense annular distribution of fan blades, but we designed it to be fixed, mainly through the calculated arc of its appearance, which plays the role of secondary acceleration of the air flow..... Let's call it 'fixed turbine';"

"After that, the gas flows through the third layer of dynamic turbines and continues to generate power;"

"After that, there is the fourth layer of fixed turbine ......"

As Marcista listened to Nesta's explanation, and the scholars around him, their eyes gradually lit up;

Their knowledge of physical physics and many other aspects reminded them that this seemed to be a viable way of thinking.

Of course, the detailed data of the various parts of the model has not been calculated, so the thing that Nesta is demonstrating at this time will definitely not work, and it will have to go through a lot of calculations and structural reorganization to really realize this solution.

But there are times when 'ideas' are really important;

Now, for example, Massta felt that the engine he had talked about was simply unaesthetically unaesthetic, and suddenly lost the motivation to continue research.

And seeing his state and listening to his enthusiasm for research, Nesta had to give Massista another fire....

He emphasized the next key work, and asked the Mechanical Research Institute to cooperate with Furnesta to put together the verification battleship before talking about anything else.

After emphasizing it many times and confirming that the guys listened, Nesta turned around and left, and called Furnesta in his office and told him the 'two-step' plan, so that he could continue the construction plan of the "Galley Gunship" while docking with the mechanical research institute and completing the sharing of data, so that the other party could develop ship engines.
