Chapter 112: Escape

The external combustion engine was invented by the Englishman Stirling in 1816, so it is also called the Stirling engine. Its heat loss is too large, so it is not the best power source, but because it does not have a deflagration stroke like an internal combustion engine, it can be done very quietly, and it is still widely used under some special conditions.

Lu Jingzhi likes guns and airplanes very much, and the Stirling engine is used more in submarines, so Lu Jingzhi has also specialized in this kind of thing, and even made a miniature alcohol lamp external combustion engine from bicycle parts - although he was beaten by his father for this, he is still very happy. The working principle of the external combustion engine is very simple, let the gas be heated and expand in the heating chamber to push the connecting rod to drive the flywheel, let the hot gas pass through the connecting pipe to the cooling chamber, the cooling chamber will disperse the hot gas, and the flywheel will drive the connecting rod to send the cold air back to the heating chamber, so that it can be heated and expanded again, and so on. For Lu Jingzhi, the advantage of this kind of engine is that it can allow the spell to fully contact the power of the elements, and will not cause a lack of energy due to being sealed in the cylinder. As for thermal efficiency, is there a higher energy source than the thermal efficiency of the spell?

At the end of the heating chamber is the Fire Elemental Convergence Spell, which is made up of the simplest alchemical formula, and this is what Tilly drew when she first drew the Spell Contract. At the end of the cooling room, the ice and snow alchemy array composed of a large number of water and air elements can also be regarded as a super complex spell. If its cooling capacity is insufficient, it is likely to shut down due to the small pressure difference between the two sides, so the technology at the cooling end is more complex than that at the heating end.

After three days of work for Lu Jingzhi with his men, the original version of the external combustion engine car was made. Since it uses an external combustion engine, three-quarters of the body is an engine, but the huge engine rarely makes a sound. It doesn't have the same deflagration as an internal combustion engine, so it doesn't need a sturdy block, and because the pressure is too small, it needs to be bulky enough to provide a little extra power.

On the day of the test run, Lu Jingzhi specially invited two lieutenant colonels and his officers to visit together. It's a show off, a show of what you're capable of, a little bit of hope for the disappointed, and a deterrent to the ones who are ready to do the tricks.

Seeing the massive body running out of 60 km/h on the road almost silently, Johnson and Anthony's jaws were about to drop.

"Why does your car run?" Johnson walked over, subconsciously wanting to touch the magical engine, but was pulled by Lu Jingzhi violently.

"That's an external combustion engine, be careful with your hands. Lu Jingzhi shouted.

Johnson was stunned, he didn't know what an external combustion engine was, because he didn't need it. After all, he's only in the Army, and those things in the Navy are too advanced for him. But he heard the warning in Lu Jingzhi's tone, and still withdrew his hand. If it is an ordinary external combustion engine, it is heated by a flame or something else, and you can see where the danger is at a glance. But the spell is different from the flame, it cannot be seen, but it can be touched. If Johnson's hand had touched it just now, it should have been cooked by now.

A captain officer obviously knew the principle of the external combustion engine, he circled around the car, and said to Lu Jingzhi with great interest: "You mean, this car of yours is an external combustion engine? But why can't I see its fire?" Lu Jingzhi took his hand and put it about 20cm away from the engine, a wave of heat rushed to his hand, warm, and the captain stretched his hand forward a little more, and suddenly felt that the heat increased a lot. He pulled his hand away suddenly, looked at Lu Jingzhi in surprise, and said, "What kind of energy is this?"

Lu Jingzhi didn't hide it from him, and said, "It's the energy of the fire element." ”

"Fire elemental?" the captain's surprise was a little amused, "are we going back to before the age of science, are we going to use alchemy and herbs?"

Lu Jingzhi said: "That's right, you answered correctly." This is alchemy. ”

The captain laughed dryly a few times, and then stopped, and he suddenly remembered that this world cannot be judged by common sense, and the undead can run all over the world on horseback, and what unscientific things are unacceptable to him? He suppressed his surprise and continued to observe the car, the body was welded by an iron frame, but the solder joints were very rough, even more ugly than the worst manual welding machine. The materials were clearly taken from military jeeps, and the wheels, chassis and drivetrain were also removed from the jeep. He suddenly asked, "Can I drive this car and try it?"

Although this car is simple, at least it took Lu Jingzhi and people 3 days of hard work to make. The captain said that he wanted to test the car, and the look of envy on his face also made it difficult for Lu Jingzhi to refuse, but Lu Jingzhi still shook his head very carefully and said, "This car is not good, there are still a lot of things we need to adjust." ”

The captain said, "I'm a mechanic in the company, and I don't know much about cars, so let me try to drive around, and I'll be able to give you a lot of advice." ”

After all, Lu Jingzhi has too little experience, and he is easy to be gullible, and seeing that the captain is reasonable, he has already moved him to go around. At this time, Anthony ran over and said to Lu Jingzhi with a sneer: "If you have anything to worry about, I can get in the car and watch him and don't let him mess around." ”

This was a more fatal proposal, but Lu Jingzhi didn't realize what the problem was at all, and after thinking about it, he nodded and agreed.

Lieutenant Colonel Anthony pretended to glare at the captain majestically, but at an angle that others could not see, but quietly made a look, the captain understood, sat in the driver's seat, and waited for the lieutenant colonel to get into the car, stepped on the clutch, hung the gear, and did not need the accelerator at all. Because this external combustion engine has always been running at full power, as long as the gear and clutch are well matched. The car moved slowly, and the captain carefully adapted to the feeling of driving, changing the speed of the car through the manual transmission, and the speed gradually increased. After two rounds on the field, the speed of the car has reached 40 km/h.

When Lu Jingzhi saw the car driving so fast, he vaguely felt that something was wrong, and shouted, "You can stop." ”

The captain pretended to be in a hurry, and replied loudly, "I can't stop, this car is out of order." Anthony sat in the passenger seat with a smug smile.

When Lu Jingzhi saw Anthony's smile, his heart suddenly brightened, this was a ghost! He immediately shouted: "Stop them! Stop them!"

Seeing the humans in the prisoner of war camp hesitantly surrounding him, Anthony immediately stood up, waved his hand, and said, "Get out of the way, get out of the way." The car got out of control. Seeing that no one was out of the way, he said loudly: "Get out of the way, obey the order!" Before being captured, he was the lieutenant colonel battalion commander, and at this time, the official authority was still there, everyone got out of the way, and the car not only did not slow down, but increased to a speed of 60 kilometers per hour, and went away.

It's not that Lu Jingzhi doesn't want to chase, he doesn't have to chase. The only car he could drive had been stolen by Anthony and his captain, and he couldn't run on two legs to chase it.

The speed of the car also aroused the alarm of the undead, and several high-ranking knights all sent out sword qi to intercept it, but it hit the steel tube frame with a loud bang, which only deformed the steel tube structure, and did not cause a substantial impact. After shaking for a few moments, the external combustion engine car quickly adjusted its direction, circled around the relatively empty barracks, shook off the pursuing sword qi, and rushed out of the barracks with the advantage of speed, and walked away without looking back.

After several scouts intercepted by the car, the car came to the vicinity of the grove battlefield and never saw a single undead army. But at this time, the car slammed and could no longer drive. The captain got out of the car and checked it, and found that there was something that needed to be adjusted to the control system. But he had no tools at hand, so he abandoned the car and dragged Lieutenant Colonel Anthony on foot in the direction of the cave.

I walked straight and exhausted, and only walked out 20 kilometers. Suddenly, they heard the sound of a stone, which startled the two people. Lieutenant Colonel Anthony jerked backwards, pulling the captain in front of him. The captain had the intention to push the lieutenant colonel back, but he lost the first move, and he couldn't break it no matter how he earned it, and he thought that the one behind him was the lieutenant colonel, three levels higher than himself, and he didn't dare to resist. While the two were struggling, two people came out of front of them, holding submachine guns in their hands, facing them.

Lieutenant Colonel Anthony and the captain stopped at the same time, and as if they had a tacit understanding, they patted the dust, flattened their clothes, and stepped forward. Anthony gasped, "Which battalion are you from?"

The soldier looked at Anthony's uniform, saluted, and replied, "I'm Carter from the 1st Platoon of Company M of the 402nd Battalion, may I ask who you are?"

Anthony straightened his chest and said, "I'm Lieutenant Colonel Anthony of the 502nd Battalion, and I want to see your battalion commander Phillips." No, I want to see the general. I have important information to tell him. ”

Carter replied, "Yes, sir." After a pause, he asked, "Can you walk?" sir. ”

Anthony felt pain all over his body when he asked this, and cursed in his mouth: "These damn undead, I can't walk." Can you find a car to take me?"

Carter replied loudly, "Yes, sir!" After a pause, he added: "Sir, this is not our sphere of influence, and it is still possible to encounter enemies, please find a safe place to hide and wait, and I will send someone to find a tricycle." ”

Anthony was taken aback and hurriedly said, "No, my matter is very important, I can't wait, go, let's go together." Give me a hand. ”

Just as Lieutenant Colonel Anthony and the others were walking towards the human defense line at the mouth of the cave, the military camp of the principality had exploded. Many high-ranking knights have been bribed by Lu Jingzhi's elemental grenades, although they don't regard this thing as a life-saving treasure, but they also know that this thing can be sold for a lot of money, so they are naturally willing to be kind to him. The average knight doesn't think so. In their eyes, it was a great shame for a human to escape from the camp of the undead, and it must be punished. And the culprit is Lu Jingzhi, a guy who can play with various elements in the palm of his hand.

How will Lu Jingzhi deal with the menacing undead knights, and what is the punishment of the undead? Please watch the next episode.
