In the office of the Speaker of the House of Commons in Newar, Androni looked up at her son who had just entered the room, and the expression on her face suddenly relaxed a lot.

"I thought you were not going to come to work today." Androni put down the documents in her hand and asked with concern, "The housekeeper said you went out without eating in the morning. Are you hungry now?"

"I've eaten outside." Dusander looked a little embarrassed, and he felt that what he did today was a bit out of control.

Androni nodded, stood up and walked quickly to the door, then closed the heavy wooden door tightly. She turned around again and pulled Dusand to sit on the sofa beside her.

"I know what you are worried about." Androni said, pulling Dusand's hand, "You are worried that our speed is too fast and the movement is too big, which stimulates the mining consortium and causes them to fight back."

Dusand nodded. Although he had no political experience, this principle could not be understood even if he did not even need political wisdom - sneak attacks could not be killed in one go, so the other party's counterattack would be a threat that would inevitably come.

"Your father and I cannot prepare for the means of leaving because of our profession and identity." Androni said to Doosand, "But you are different. I discussed with your father and used the relationship between the Marquis in the Star Sea Federation to arrange a refuge route for you."

Dusander was stunned. He was stunned for a while before asking back, "What about you?"

"We can't leave." Androni smiled gently, and she rubbed the brown hair on Dusander's head. "Your father and I also have our own evacuation route, but we cannot have anything to do with the Marquis. This is the Empire. If your loyalty to the Empire and His Majesty is not absolute, it is absolutely disloyal."

Dusand took a deep breath, "Mother, then we can't do this - not just for ourselves..."

"Yes." Androni nodded, "It's not just for herself." She smiled and looked down at her abdomen, "I originally planned to tell you about this news in two days."

Dusand was stunned. He was stunned for a long time before he pointed to Androni's belly tentatively, "Here..."

"I don't know if you have a younger brother or a younger sister." Androni hugged Dusander's head and gently kissed his forehead. "But, for his/her safety, I will definitely be careful."

Androni hugged Dusand and said confidently, "I believe you will definitely be a good brother."

Dusand, who appeared in the car factory, listened to Polina's report for half an hour, and then came to his senses amid the question "Did you hear me?" that Polina repeated six or seven times.

He looked at the teacher who seemed to be about to go wild, and his mind changed a little, and decided to admit his mistake immediately to avoid being beaten by the muscular teacher on the ground.

"I encountered something today." Dusand said to Polina in a low voice, "Teacher Polina, can you recommend books on parenting and taking care of pregnant women?"

Dusand planned to tell Polina about his upcoming brother or sister in advance, and then save himself from being beaten. What he didn't expect was that he was preparing to open the topic as the opening question that led to the topic and just blurted out, Polina slapped him.

Not only a slap, Polinna directly gave Dusande a set of "combos". In the shocked and even horrified eyes of several factory managers and accountants, in the "default" of the guards who were not surprised to move their eyes away, Mr. Dusande, the "secret" red-clothed postman, the chief private secretary of His Excellency the Speaker of the House of Commons, the owner of the factory was punched and kicked by the Imperial technician all the way to a corner without anyone.

"What are you doing?!" Confirm that there is no one around, Polina began to hysterically at Dusander, "Lorrene is only sixteen years old, you are only fourteen!"

Dusand instantly understood what Polina was angry about. He wanted to explain it with a little amused and crying, but Polina, who was in a state of extreme worry and anger, did not give Dusand any chance to explain.

She poured her anger and worries at a very high speed.

"She is only sixteen years old and is still in the development stage! It's too early for civilians to be a mother at this age, and even earlier for her!"

"How can you take the responsibility of being a husband and father at your age?"

"Oh my God, you have to hold the wedding quickly. I have to go and talk to Mrs. Androni right away. Have you told her about this?"

"Can you be sure that Lorraine is pregnant? Has she been to the hospital? Don't go to the church hospital, it's too conspicuous..."

Dusand took a deep breath and said in the calmest tone possible, "You misunderstood."

"Oh? It seems that you are quite smart and didn't go to the church hospital..."

"I mean pregnancy," Dusand explained quickly, "It's not Lorraine, it's me who want to be my brother."

Polina stopped talking, opened her mouth wide and looked at Dusander. After a while, she suddenly said, "Is it Mrs. Androni?"

Dusand nodded solemnly, and then explained seriously, "My father looks good in physical condition."

Polina's face suddenly turned red. She covered her face with her hands and began to apologize. She tried her best to coerce and induce, hoping that Dusander would lose his memory in just a few minutes immediately.

"The only thing that is thankful is that you didn't directly scold me in front of the managers and the accountants." Dusand said with a smile. "I think you can explain that you are trying to get over it because you know the new solution to the tank engine."

Although the body hurts, you still have to keep smiling and be so angry.

Well, it's actually not very angry. Dusand felt that he always maintained a strange...lightly floating feeling. This feeling is very special. It must have a joyful part in it, but at the same time there are all kinds of strange...unspeakable feelings mixed in it.

Androni is pregnant. From a certain perspective, Dusand is sincerely happy for her and Duchamp. To be honest, this child is strictly their child. Instead of an "assembly machine" with hardware provided by Androni and Duchamp, but secretly housed an operating system called "Time Traveler".

On the other hand, Dusander had to worry about the impending child.

According to the information "provided" by Mr. Marquis, within four months, Nuozar will face attacks from the alliance's main fleet. In the face of war, any life will appear extremely fragile. Nuozar in the midst of war is definitely not a suitable place for pregnant women to prepare for delivery.

At the same time, Androni may also face revenge or even infight from the Imperial Mining Federation. Such attacks may come from invisible and intangible political fields, or may directly come from a more "specific" and practical level.

Even people like Harold know that the best way to destroy the enemy is to kill them physically. How could the mining consortium not know this?

Dusand took a deep breath and decided to do something practical work that could make his family safer.

For example, get the tank out first.

"The tank's engine compartment can be enlarged a little more," Dusand told Polina. "The track-drive technology does not necessarily require it to be particularly durable. We can make it easier to replace the track."

Today's experimental tanks mainly face three difficulties. The engine power is insufficient, the track material is unqualified and it is easy to break, and it is difficult to use existing production lines for large-scale production.

In terms of engine power, Dusand's solution is very rough. The largest engine that the entire car manufacturer can manufacture is v12, but this kind of engine is too big. Secondly, the inline eight-cylinder engine is actually a better choice.

A single gas inline eight-cylinder engine is not enough to allow a tank weighing up to 30 tons to achieve a speed of fifteen miles per hour on a flat road. The compressed ignition method of the gas engine results in considerable torque but insufficient horsepower.

The solution Dusand came up with was very rough. One inline eight-cylinder didn't work, so just use two.

Unlike cars, tanks themselves do not have the traditional "steering wheel". Its steering is achieved through the difference in the running speed of the tracks on both sides.

The tanks now manufactured experimentally are driven by an inline eight-cylinder engine. When steering is required, the operator must release the clutch inside the track drive wheel on one side and lock the track drive wheel on this side. Only then can the direction adjustment be achieved.

If you accidentally adjust the direction too much, you can only let the tank resume straight driving, and then do it again according to the operation just now, lock the track on the other side to adjust the direction.

This is too inefficient.

Dusand's solution comes with an innate benefit. Two inline eight-cylinder engines drive one side of the tracks, so that the steering maneuver can be achieved by adjusting the running speed of one side of the engine during driving.

"The imaginary enemy of the tank is the Alliance's steam knight, so the firepower configuration must have sufficient armor-piercing capabilities. At the same time, we must ensure that our tank can defend against the opponent's armor-piercing hammer and six-inch hand-cannon attacks." After temporarily solving the two major problems encountered by the tank in a few words, Dusand put forward new requirements for his "project chief designer". "I require the tank to maintain a low posture to avoid direct fire from enemy fire. At the same time, the original vertical armor design needs to be changed - to an inclined armor design."

The tank design plan that Polina came up with was completely her own creativity. From all angles, her designs were full of "beauty".

The tank itself does not have a suspension system. At the same time, she also designed the Navy's ship firepower layout and installed four 5-inch short-body guns on Dusand's "30-ton tank". Two are on the left side of the tank and two are on the right side.

At first glance, this thing looks like a shoe box with four pencils pierced through the side wall.

Dusand did not reject this design plan at the beginning. After all, it was Polina's design, and it was more in line with the parameter requirements proposed by the Army and Navy Commando. Although from the perspective of modern people, it is by no means a qualified tank, as a firepower bunker with certain protection capabilities and can move on its own, Polina's design is definitely successful.

Dusand, who originally wanted to fish, was inspired by the double stimulation of the alliance's impending invasion and his mother's pregnancy, prepared to take out some of his previous experiences and greatly improve the imperial people's understanding of "tanks".

A real tank should be a war machine that takes into account both mobility, firepower and protection. It is not an auxiliary role, but a killing machine that should be used in a concentrated manner to completely break down the enemy's defense line and use artillery and heavy machine guns to harvest lives.

"This is what I imagined for the tank..." Dusander squatted down and began to paint on the ground with branches. Soon, a familiar image of an egg-type turret loaded with a cannon, and the height of the track does not exceed the waist of the body, appeared on the land of the empire.

"The tank itself is divided into two parts: the turret and the body. The turret can rotate, and the barrel can be raised or pressed down." Dusand explained to his "design". "The turret uses casting, which can speed up the manufacturing progress. The body uses an inclined armor design, which can reduce the weight of the vehicle and reduce the difficulty of processing."

What Polina is more curious about is the driving part. She pointed to the rough graphics on the ground and asked, "How can we achieve this design of five wheels supporting tracks? Our tracks are not strong enough now. Such wheels are directly connected to the tracks, which may cause great stress during off-roading, which will cause the track to collapse."

"Tanks need to be suspended, too," Dusand said bluntly. "Its suspension cannot be too high or exposed to become a weakness. My idea is to use metal sticks as a source of power to provide suspension deformation."

Dusand's "design" is simple. It will be a Type 59 tank powered by 18 compressed-ignition gas cylinders, with an oval turret and torsion rod suspension, and uses five pairs of load bearing wheels and two pairs of power wheels to drive two tracks.

As long as the Allies dare to come, let the tank army directly run over their positions and use the brains and blood of these racists to lubricate the tank's tracks!

"It's not difficult to achieve in principle." As a great technician who is used to Dusand's "engineering genius", Polina quickly accepted this setting and began to analyze the difficulty of manufacturing the tank. "Other questions are easy to say. If you cast a turret, it's not very difficult to build in batches. It's just that driving may be a bit troublesome. Two engines may be able to be stuffed into the body, but two sets of gearboxes are absolutely impossible to fit into the tank."

"The drive device can be simplified. This tank does not require particularly fast maneuvering speeds." Dusand said after thinking for a while, "two to three forward gears and one rearward gear, which is basically enough. There is no need to go directly to a five-speed or even six-speed gearbox like a car."

"The gun may also need to compromise - the barrel you drew is too long, and the gunpowder fired smoke is not easy to drain." Polina said as she thought, "The 5-inch short-barrel howitzer is actually good. I asked the Navy Commando, and they said that there is no problem with the cannon of this size being used to blow up the Steam Knight."

The two of them squatted on the ground and started a heated discussion. The manager and accountants of the car factory who were secretly lying in the corner from afar looked at each other. They didn't know whether to invite these two people to the conference room to continue researching or to stand there waiting.
