When driving, explain the working principle of an internal combustion engine to a person who does not have the knowledge of mechanical design principles. This process will inevitably be painful and even tormenting.

However, it is always a good thing to have someone to talk together, and Dusander quickly found an explanation that Mr. Captain could accept.

After changing all the professional vocabulary of "burning", "working", "explosion" and so on to "explosion", the Captain instantly understood what Dusand was talking about. Moreover, his interest in chatting became higher and stronger.

"A certain proportion of air mixed with combustible gases will ignite after being compressed, and then an explosion occurs in a small space." Dusand explained the principle roughly, then stepped on the accelerator hard. Then he frowned, "It seems that the air pressure in the cylinder is not enough."

When I stepped on the accelerator before, the engine would change its speed according to Dusand's foot step. But now, after the accelerator is pressed, the engine's running speed seems to be almost the same as when I didn't step on it.

Due to the rush to work, there is no speedometer, no tachometer, and naturally no fuelmeter on the No. 2 of the experiment car. Dusand had to rely on the little experience left to this day when he took the driver's license ten years ago.

Now, there is no response when stepping on the accelerator. Dusand judged that the possibility of exhaustion of gas stored in the gas cylinder was relatively high - of course, it may also be because the pull rope that controls the release of the gas was broken. You need to determine the reason specifically, just change the gas cylinder to know.

Dusand stopped the car and then turned off the fire. He said to the Navy Captain beside him, "Please be warned, I will go to the carriage behind to get the gas cylinder."

There is no doubt that for a convoy that may be ambushed, the safest situation is of course during the maneuver. As long as the convoy is moving, it will become very difficult for the enemy to ambush the convoy - shooting the moving object is actually a very difficult thing.

In order to have the ability to attack moving objects, the army specially purchased large-caliber air-explosive shells and fully automatic firearms. It is obvious that the bandits would not have such things - they are at most equipped with single-action rifles flowing out of the army. Such weapons are not suitable for attacking moving objects.

Therefore, the convoy was most vulnerable when it stopped. Dusand asked the Captain to watch out and went to get the gas cylinders himself, in order to minimize the risk of injury to the person after the attack.

Although it is used as bait, if someone is injured when it is bait, it will be difficult for people to accept it. It is best to knock off a little bit on the added armor plate and then wipe out the enemy completely.

After adjusting the buttons in the Steam Knight to the high torque mode represented by the mountain, Dusand made a whirlwind and walked towards the logistics carriage and began to unload the goods down.

Lorraine was sleeping in a daze in the carriage. After seeing Dusand wearing steam knight armor, she screamed several times. Dusand finally had to take off her helmet, and then comforted her with Polina for a long time, which calmed down the little girl who was confused.

Carrying the gas cylinder and changing the fuel, Dusander rebooted the vehicle with a rocker, then climbed into the cab and prepared to drive forward.

Then he found... the Navy Captain was gone.

According to the original plan, the Navy Captain in Steam Knight armor will be responsible for protecting Dusand's safety throughout the process and provide observations when Dusand repairs or reloads the vehicle with fuel.

But now, the person in charge of the observation and protection is gone.

In the hilly areas of Shaoshu, a steam knight who was more than two meters high and nearly three meters could not disappear out of thin air. Dusander immediately felt a chill behind his neck. He ignored everything else and jumped to the roof of the car and began to observe the surrounding environment.

The officer car parked behind the experimental car No. 2, about one hundred Yolls, also found that the situation was wrong, and the response measures they took were a little incomprehensible to Dusander - the roof of the carriage suddenly cut open, and a brass instrument that looked a bit like an ancient armillary sphere appeared on the roof.

In the center of this instrument, there is a huge lens about one yoll in diameter, and in the lens is a calcium stone about the same size as Dusander's head.

One hand reached out from the carriage, and there was a lighter in his hand. It seemed that if the situation was wrong, they would immediately light the fire.

Dusander only glanced at the instrument and then focused his attention on finding the missing Mr. Captain. Dusander didn't care about what the machine was and when it should be used. He just wanted to know what the Captain had encountered.

Just when Dusander was almost unable to hold back his anxiety and was about to drive away first, a burst of soil suddenly rose on the hillside more than 300 o'clock.

A few seconds later, a human-shaped monster covered in mud jumped out from under the ground. Its hand was still carrying a person - this poor man appeared from the ground with his thighs facing downwards and in a mess. He kept trying to resist, but whether it was the dagger in his hand or simply hitting it with his fist... it had no effect on the human-shaped monster.

Dusand was a little nervous. He was about to adjust the knob in the Steam Knight to the fire level. Then, he saw the human-shaped monster walking towards him in the distance. As he walked, thick white steam was sprayed out from its joints and back.

That's not a monster, that's the Captain who just disappeared!

The Captain carried the poor "captive" all the way to the car, and then came out of the Steam Knight's armor.

The Steam Knight maintained a erect posture, while the captain was still caught in its palm. It can be seen that the action just now consumed a lot of energy from the Captain, and even the beard on his face was wet.

"This guy, just peeked at this tunnel next to him." The captain explained to Dusand why he suddenly disappeared. "He has weapons on his body, and after seeing me discovering him, he immediately crawled into the tunnel. This man should be a spy."

Dusand glanced at the "spy" with his head facing down.

His figure is very clean, and his clothes are torn. His hair is long and messy, and he also has a strong smell of bad smell on his body - there are many scars on his arms.

What attracted Dusand the most was the tattoo under the spy's neck.

The quality of the tattoo looks very good, it clearly depicts a warship firing in deep air. Around the battleship pattern is a circle of text that Dusand cannot understand.
