Mage? Spell Engineer!

The prime minister was surrounded by three mages and got into Rorschach's black and red car. The appearance of the vehicle attracted the attention of masters and viziers.

Since he wanted to avoid showing up, the prime minister got into the car first with his hat in hand. Humboldt even turned around curiously. The large magic lights on the front and rear and the windshield were all different from the carriage. The most important thing was that the shape reminded him of Beetle.

He was the last one to get in the car, and Rorschach sat in the passenger seat. The Prime Minister had already naturally closed the curtains in the back seat, and quietly pressed the leather chair to experience the elasticity of the seat.

"No horse? No construct?" Master Humboldt was very curious about Rorschach's car, looking around and touching it.

"The power source is at the front of the car."

Humboldt thought of the protruding space in front of the car's cockpit: "Is the construct inside?"

No, why are you always thinking about bionics? Is it possible that there is a golem in the front of the car pedaling or running on a hamster wheel? Rorschach revealed the principle without any secret: "The source of power is a set of alchemy tools:

“The cylinder has a built-in magic circle that can compress the air and then release it to push the piston embedded in the cylinder.

"The piston drives the crank, converting its reciprocating motion into circular motion, and drives the hub through the bearing. But there is also a flywheel, which uses inertia to divert part of the output to drive the system to the next cycle.

"The power source of the magic circle comes from the special alchemical potion, which is pumped in and out of the interlayer of the outer wall of the cylinder within a cycle to supply energy to the magic circle."

The principles described by Rorschach basically copy the internal combustion engine. After all, if you don't know the principles of these power engines, you don't know thermodynamics well. If you don't know thermodynamics well, you don't know a good chemical engineering dog.

But this "pneumatic engine" does not have the process of fuel gasification and deflagration. Instead, it is based on the formation of [Rorschach's Air Cannon], which compresses the air in a very short moment. [Air Cannon] itself is also an instant release spell, it replaces deflagration. This is the method Rorschach has found to currently create the maximum torque, while also avoiding the harsh working conditions of the combustion chamber. The requirements for technology and materials are naturally much lower.

Other spells that can output kinetic energy are either too powerful and the steel components cannot withstand long-term impacts, or the instantaneous power is insufficient and the torque and peak power provided to the car do not meet the requirements.

What the pneumatic engine "burns" is not oil, but a special alchemical potion - "slurry water" obtained after the death of living water bacteria cultivated at a high concentration. After being completely inactivated, it is immediately put into the transmutation dust powder, melted and stirred evenly to obtain it. A relatively thick blue-purple pearlescent liquid. The consistency gradually decreases as the magic contained within is released.

Of course, no matter how low the process standards are, there are still limitations. For example, the current pneumatic engine polished by Goblet Precision Factory only has a maximum of 13 horsepower in two cylinders. If the materials are piled higher, the small difference in the stroke of each cylinder will be exposed, and the entire system will be exposed. Unable to operate stably.

Generally speaking, this thing can be called an "air car". It uses air as the medium and is very environmentally friendly.

Rorschach introduced a lot in the passenger seat. Master Humboldt beside him was silent, nodded and then smiled: "Okay, most of them. I didn't understand."

It was rare for Otto to listen to the conversation between two mages (the emperor of the empire was quite ordinary). He listened silently and didn't realize how serious he was. However, he didn't expect that the archmage couldn't understand what the junior was talking about, and he didn't expect that the archmage was very straightforward. Admit this point blankly. The different styles of mages and politicians can always give the prime minister a small impact.

He took out his pocket watch to check the time and coughed in the back seat: "Sorry, gentlemen. I still have an appointment with His Majesty Albert, can you take me to the palace?"

Humboldt nodded: "As you wish, sir." Then he turned to Rorschach and asked: "Why doesn't the car leave? Where is the driver?"

"You are sitting in the driver's seat, and the coachman has been locked out by you." Outside, Andre slapped the door until his hands were numb. He kept using [Messaging Technique] to call Rorschach, expecting him to remind Master Humboldt to change. seat.

Humboldt nodded again: "I see." Then he got out of the car slowly, walked around halfway and sat in the back seat.

Is it because you have been practicing natural magic for a long time? Do you have to return to your original nature or stay in a natural state? Rorschach discovered that the "calmness" shown by Master Humboldt before could be understood from another perspective.

However, it cannot be ruled out that he did it on purpose. The evidence is that as soon as the master got into the car, he fumbled here and there, then firmly held the steering wheel, and entered the "driving posture" without a teacher. And even if the car windows were soundproofed, Humboldt would definitely be able to hear Andre when he knocked on the door and knocked on the window.

Andre got in the car and used [Messaging Technique] to complain to Rorschach: "Teacher Rorschach, you didn't remind the master either."

"You can remind him yourself. Double-glazed glass is soundproof and does not block [communication technology]."

"I used it! But the master ignored me." Andre complained while driving: "I think the master must want to try driving. He is interested in this car."

"Yes, I'm interested." Humboldt's sudden inclusion in the conversation of "Messaging Technique" startled Andre. Rorschach has been through this before, so he remains calm:

"As I said, [Messaging Technique] is not absolutely private."

Humboldt asked many more questions and got new terms such as "suspension" and "differential gear". But what he cares most about are horsepower, speed and other indicators. Andre combined the actual road conditions to demonstrate and teach the master how to accelerate, turn and brake on the spot.

Although the three mages had a lively chat using [Messaging Technique], our great Imperial Prime Minister Mr. Otto could not hear anything. With the degraded hearing of the elderly, he felt that the silence in the carriage was too much.

Originally he should have been silent, but thinking about his mission here, he coughed to break the "quietness". The prime minister's cough interrupted the lively conversation of the three mages. Rorschach turned his head and looked sideways, Andre looked at the prime minister through the rearview mirror in the car, and Humboldt even raised his hand to release a small healer.

The prime minister was illuminated by the green light: "Thank you, Alexander." Mr. Otto found that compared to the crown prince, he was even less able to deal with these spellcasters who were inconsistent with normal people's minds. The prime minister also chose to start with this strange vehicle: "Is this alchemy car expensive? Can it only be operated by a mage?"

"The driver does not need to know magic. The driver who drives a horse-drawn carriage or an ox-cart can also learn to drive it, sir. The price of the car will be reduced when the technology matures, but it requires alchemical potions to operate, which must be provided by us."

Prime Minister Otto nodded: "That is of great promotion value. Maybe nobles and wealthy people who pursue novelty will buy such an alchemy car."

"The ideal situation is that every family in the country can own such a car for transportation." The Beetle belongs to the public!

The prime minister only thought that the young man was joking. Now not every household in the city can afford to buy and maintain a carriage, let alone an alchemy vehicle: "Every household has a carriage. Master Rorschach, I found that you have the talent to be a parliamentarian. He is good at constructing a beautiful vision for the people." He said with low emotional intelligence, the prime minister felt that someone was farting with his mouth in a closed carriage.

"You are very discerning. But it is my friend who wants to be an Imperial Councilor, not me."

Is there a pro-Imperial faction around Rorschach? Otto silently took note of the other person's casual remarks.

After the car arrived at the palace on the outskirts of the city, Otto got out of the car. At this time, his secretary, guards and other people were already waiting eagerly at the entrance of the palace. The prime minister gently shook Rorschach's hand for the second time: "For the first time, I hope the journey can be longer. Master Rorschach, you are a very interesting young man. I look forward to seeing you again."

"I have a feeling it will be soon." Apparently he had been investigated by the prime minister, and the old man came prepared.

"Yes." After saying that, the prime minister stepped on the red carpet and walked into Byrne's palace gate lined by guards.

He climbed back into the car, followed by Humboldt. Rorschach was slightly surprised, but the master just ordered him to drive to Kempson: "There are only grape fields nearby, go to your place."

The "Qi Car" started, and the indicator light showed that the magic concentration of the alchemy potion had reached a low point. Although you don’t need a mage to drive, having a spell caster in the car will bring you a benefit:

Rorschach held the shift lever in the passenger seat and pumped magic power directly into the alchemy potion from the mithril alloy rod embedded in the lever.

"Okay, teacher, the cylinder will burst again if you recharge it again." Andre reminded Rorschach to stop, then restarted the vehicle and drove towards Kempson.
