Vol 2 Chapter 61: Mechanical pioneer

A week ago, Betty heard the black cat Bayern's perfunctory remarks at the party, but fell into deep thought. She dragged Donna back home and began to devote herself to research.
"I don't have to want to create a mechanical giant from the beginning, that would be too delusional!"
Betty looked at the small steam boiler in front of her, lost in thought.
"I should start with a simple and miniaturized direction. A mechanical assistance facility similar to armor may be a good research direction! However, I have to solve the mechanical power problem first. If it can't be self-driving, I will make it with the group. The blacksmiths who enchant weapons and armor are no different."
Donna looked at Betty who was talking to herself. She was sometimes excited and frowned when she looked at her. She couldn't help but feel helpless, and picked up the exercise book Betty prepared to continue studying.
Donna didn't want to rely on Betty, the wonderful world of magic, she also wanted to explore, and wanted to create a magic model by herself.
"The so-called power is the core of the drive. I have already understood the basic principle of steam drive. First, there must be a boiler to generate a lot of steam. Thanks to Bayern’s discovery of the density rune, let me know that water can be used. When expanded and compressed, steam can expand. This process of boiling water is the process of expansion."
Betty engraved a secondary rune array composed of secondary fire element runes and secondary searing runes on the bottom of the boiler. This is a secondary rune array designed by Betty to heat the boiler, and she named it the thermal power rune. Wen Zhen.
Before meeting Bayern, she had already designed the thermal power rune array. After many explorations and modifications, she found a suitable searing effect, which can continue to heat the boiler with magical power.
At this point, the research has entered a bottleneck. The steam boiler needs a lot of water. The mechanical giant she envisioned can only carry a large number of water tanks on his back, which is very heavy.
The arrival of Bayern solved all this. He discovered the secondary water elemental series of runes, especially the secondary density runes and the secondary pressure runes. The moment Betty saw it in the magic book, she wanted to jump up with excitement.
With the secondary water element series runes, Betty's mechanical equipment miniaturization can be solved.
She consulted Bayern, who had rich experience in experimenting density runes, found a suitable density, and designed a secondary water vapor rune array.
This rune array can produce a large amount of water vapor in an instant, and driven by the thermal power rune array, through the effect of pressure runes, it can instantly produce high-pressure water vapor.
"The operation of the steam engine mentioned in the books of early civilization requires a sealed cylinder and a moving piston. If there is no magic, the problem of light sealing is difficult to solve, but with magic, these are not problems!"
Betty's eyes were bright, and her small body seemed to contain great abilities. She skillfully used two secondary spells. The second outstanding achievement of the Enchanting Fellowship Research Association is the secondary high-burning spell model and the secondary air shaping spell model.
As long as it provides sufficient magic power, the secondary high-burning spell model can create the highest temperature that the secondary fire element series can reach, and easily turn iron ore into iron juice.
Betty prepared the magical iron block, turned it into molten iron with a secondary high-burner, and then used air to shape it with the hand of secondary magic to successfully cool the iron and form a small cylinder at one time.
At this point, Betty was stumped. The book in her hand is vague and only mentions the reciprocating steam engine, which uses steam to expand the piston to do work.
"Steam expansion can indeed push the piston, but how do you get the piston back? This book is unclear. I will try it first..."
boom!
Betty's prototype steam engine had no vent, and the explosion ended.
Betty, who promptly inspired the secondary magic crystal shield, looked ugly, and continued to experiment. This time Betty added an exhaust port to the prototype steam engine, but it could not solve the problem of piston reciprocation.
"The power I created must be able to push a main bearing wheel to rotate, and then drive the entire machine to move through gears, resulting in double the attack power and moving speed."
"So, another way of thinking. I need a facility that allows the piston to circulate and push the main bearing to continuously rotate! Maybe this can be done!"
After many failed experiments, Betty realized a condensing vacuum steam engine, but the power of this steam engine was too low to drive her ideal machine.
She quietly took away the books of the ancient civilization from her father's study, and accidentally found the incomplete drawings of the reciprocating steam engine, and finally solved the problem.
She made a closed sliding valve chamber from the steam inlet, with a built-in sliding valve connected to the pulley rod, connected to the eccentric wheel, connected to the piston rod through the crank and connecting rod, and finally realized that the steam in the cylinder pushed the piston to reciprocate.
After the entire prototype steam engine was successfully made, Betty began to continuously try to miniaturize the prototype, and finally she made a portable magic steam prototype.
"This way the most important power problem is solved! Thanks to Bayern's water element series of runes, otherwise this prototype machine will not be able to be successfully manufactured. Now I will assemble the machinery I have already done, and I have already figured out how to assemble it. ."
Donna looked at the smaller Betty carrying a prototype that was almost as high as her back, and looked at her worriedly.
Betty has made piles of parts a long time ago. She has a series of ideas, but it is limited to being unable to create a strong power core and cannot be realized.
In her magic book, a large number of imaginary designs of giant machinery are recorded. Now is the moment when dreams are reflected in reality. Although it is impossible to make an extra-large mechanical giant, it is possible to make an enlarged auxiliary mechanical device.
She melted and reshaped the large magical parts ~EbookFREE.me~ It took about a day to successfully assemble the steampunk-style mechanical equipment.
Two auxiliary mechanical legs and one auxiliary mechanical right arm and the core device of the back. Because of the limited materials, the left arm is tightly equipped with a wristband inscribed with the magic crystal shield rune array, and finally formed this somewhat bulky auxiliary machinery with a height of two meters .
"You're called the Apprentice Combat Aid Type 1, or Apprentice Type 1 for short. This name is really good. It fits the description style in the books of ancient civilization. I'm really a genius!"
The Apprentice Type 1 manufactured by Betty is connected to Betty through the magic of the back. It requires Betty to consume mental power to guide the magic to enter, inspire several runes in the prototype, and achieve the purpose of producing a large amount of steam for work.
The exhaust hole is immediately above the right arm. There are five very small holes. Guided by the secondary direct fire rune array, it can instantly release ultra-high-pressure and high-heat steam missiles with excellent killing effect.
The mechanical arm is equipped with two solidified magic crystal weapon runes (the magic crystal short blade and the magic crystal spear), which can be used for close combat whenever necessary.
Relying on the prototype on the back, the entire Apprentice Type 1 can greatly enhance the user's instantaneous movement speed and attack strength, and produce stronger power and speed than ordinary enchanting martial arts.
The only downside is that, compared to the flexibility of enchanting martial arts, the Apprentice 1 is a bit clumsy. Because of the use of enchanted iron as the material and the engraving of multiple secondary strengthening runes, the strength, hardness, and toughness of the entire machine are greatly improved, and the defense effect is also greatly increased.
Apprentice Type 1’s back base, shoulder base and double foot base have a special instantaneous steam drive device, which can discharge a large amount of high-heat steam instantaneously, which can kill the enemy or drive instantaneously to achieve fast movement and short low altitude flight Various effects such as broken arm attack and broken arm self-destruction.
