The tank factory had no heating facilities. In the space that stretched for a kilometer, there were various cold metal devices scattered around.

Especially when the dome exhaust fan was running, it circulated the air, blowing a cold breeze.

Xu Fei stood in front of the Grizzly tank, feeling the warmth brought by the two orange-red headlights. He couldn't help but call out to the engineer, "Take this thing apart and put it in my office as a stove."

"Yes, Factory Director!"

At the same time, the Grizzly tank was finished with its debugging.

Da Ma ran over in a hurry, "The base has given us half a box of military diesel. Should we take advantage of the darkness, when there's no one outside, and go for a spin in the Large Swamps?"

"Let's go!"

A moment later.

The Grizzly tank rolled over the metal conveyor belt and entered the power plant area of the Large Swamps.

It was already 8 o'clock in the evening, and the construction site had long been off work.

Xu Fei sat in the narrow cabin and quickly mastered the tank commander's observation and aiming system with Da Ma's guidance. Through the night vision device, he saw the green scenery outside.

It was his first time riding in a tank, and not only did it feel fresh, but he was also particularly excited.

This novel is available on bit.ly/3iBfjkV.

But he always felt a strong smell of diesel inside the cabin.

"Is there an oil leak?"

"No, this is the smell of war!"

As Da Ma spoke, he held the steering wheel with his left hand and clicked a few buttons with his right hand. "Hold on tight, we're accelerating!"

Xu Fei grabbed the handle above his head and curiously asked, "Steering wheel? Isn't it a control lever?"

"It's a hydraulic mechanical automatic transmission, automatic shifting, five-level hydraulic power steering. You can drive it as soon as you get in, and you can also operate the machine gun. Who needs a control lever?"

"Indeed, times have changed!"

In their conversation, the light tank entered the Large Swamps.

In the winter, the saline-alkali land, without rainwater nourishment, quickly turned into dry and sandy soil.

The light tank raced along, kicking up a long trail of dust.

Sprinting, sudden stops, lateral turns...

It looked exciting, but it was boring to sit inside.

Because you could only rely on the night vision device to observe the green night scene.

Xu Fei immediately switched positions with Da Ma and personally drove the tank.

The automatic transmission was indeed easy to learn. Remember a few key points, practice a few times, and even learned how to drift.

But it was completely different from what he had imagined.

According to Xu Fei's idea, he should push left and pull right, step on the clutch with one foot, step on the accelerator with the other foot, shift gears and downshift at the same time, hands flying, accelerating with a strong sense of power.

In short, it should be exciting!

But now...

Just step on the brake and accelerator, and then sway the steering wheel left and right, nothing else to do.

After running for more than ten minutes, it was not as comfortable as driving a small four-wheeled agricultural vehicle.

So, after a short spin, in less than half an hour, Xu Fei, who was still unsatisfied, returned to the tank factory with Da Ma.

Two hundred engineers had already dispersed, leaving twenty people to dismantle the tracks and chassis.

According to the original plan, after dismantling, the light tank would be sent to the repair workshop for repairs, then driven out, dismantled again, sent in for repairs, and so on...

By doing so repeatedly, only a small amount of resources would be consumed, and countless tracks could be obtained. It wouldn't take up too much electricity, and there was no need to prepare so much energy and rare earth minerals.

In fact, during the production of the first Grizzly tank, Xu Fei had tried to manufacture tracks.

That is, he arranged for engineers to independently produce them in the track workshop.

But the base gave a series of prompts.

First, input a small amount of metal iron and a small amount of rare earth minerals, and start up the No. 1 smelting furnace.

Then, input a small amount of metal iron and a small amount of rare earth minerals, and start up the No. 2 smelting furnace.

Then, input a small amount of metal iron and a small amount of rare earth minerals, and start up the No. 3 smelting furnace.

Subsequent energy consumption, start up the ordinary machine tool and precision lathe respectively...

After doing this, they almost ended up with a second Grizzly tank.

In other words, the tank factory was an integrated production line. If a certain component was produced separately, it would affect the entire production. If there were not enough resources, production would not be allowed. If there were enough resources, a new tank would be given.

Half an hour later.

Xu Fei obtained two sets of headlights for the Grizzly tank.

[Infrared Halogen Headlights: Internally adjustable color temperature and controllable power halogen bulbs, externally retractable filters.]

When the filters were retracted, it only required 80W to 100W of power to achieve strong penetrating illumination in low visibility environments.

When the filters were placed, visible light was blocked, and infrared light was emitted outward and received reflected signals, allowing the detection of hostile targets. The maximum power was 800W, and the maximum detection distance was 1200 meters.

[Note 1: Do not transplant to heavy tanks.]

[Note 2: Please prioritize the use of laser rangefinders and night vision devices.]

"Whether there are filters or not doesn't matter, the key is to keep warm."

Xu Fei asked the engineer to find a plug to connect it, and then removed the control switch from the Grizzly tank.

Find any power source...

The lights turned on, and the heat wave hit, but it was particularly dazzling.

"Not only do I need to weld a support frame, but I also need to figure out how to not have the light shining on people, but still feel the heat."

Xu Fei pondered for a long time and came to the area where the basic production line of the tank factory was located.

He started the computer that came with the Level 3 basic production line and entered the infrared halogen headlights.

Sure enough, just like the motor, it could only produce light bulbs.

Large light bulbs, small light bulbs, miniature light bulbs, but they couldn't produce devices with lampshades or lamp housings.

And starting a new Level 3 basic production line to manufacture lampshades and lamp housings would also consume electricity.

"For now, dismantling the light tanks is the most suitable. At least we can get finished products, switches, and wires."

Xu Fei pondered and designed a support frame to fit the infrared halogen headlights.

Although he couldn't manufacture the light fixtures, the base still provided relevant parameters.

For example, adjusting the power to change the brightness.

For example, adjusting the color temperature to change the infrared spectrum.

In addition, infrared light is an electromagnetic wave that is accompanied by an alternating electromagnetic field during propagation. It causes the alternating polarization of molecules in the material, resulting in the back-and-forth relaxation motion of a large number of molecules. These molecules will collide and rub against the material during motion, resulting in the infrared thermal effect.

And this infrared halogen headlight that came with the Grizzly tank, in order to achieve the maximum thermal effect, the power must be fully opened, 800W, and the spectrum should be set to 2500k.

Xu Fei made several adjustments and saw his own radar module. A flash of inspiration struck him, and he found a way to prevent the light from shining on himself.Like an open umbrella, using the infrared halogen lamp as the umbrella handle, it illuminates the inside of the umbrella. The interior of the umbrella is fish scale-shaped, causing the strong light to scatter, while also enhancing the heat effect of the infrared rays.

The scattered light and infrared rays, unlike a concave mirror, do not converge on the umbrella handle, but spread out in all directions.

In this way, facing the inside of the umbrella, one can see the light and feel the heat, but it is not dazzling.

"Smart as I am!"

Xu Fei finished the design, carefully examined the umbrella, and added a base to it.

Then he found that this thing looked a bit like a pedestal fan.

"What is this? An electric heater fan? But there are no fan blades."

"Electric heater cover?"

"Or an electric heater?"

Xu Fei pondered for a long time, removed the infrared halogen lamp, tried to install fan blades, and surprisingly, it worked.

And changing the fan blade drive to a spring...

[Complex mechanical device.]

"It can actually be put into production."

Xu Fei was a bit puzzled, found the second-level basic production line that produced Phoenix Daqiao, opened the model slot, and set the quantity to 1.

A moment later, a spring pedestal fan appeared before his eyes.

He removed the spring and fan blades, installed the infrared halogen lamp, then drew out the wires and switch, and finally connected the power supply.

He turned on the switch and adjusted it to maximum power.

The silver fish scale-shaped reflector scattered the light in all directions, and the temperature of the nearby air quickly rose.

Looking at the orange-red glow and feeling the heat wave coming over, Xu Fei couldn't help but feel a sense of pride in his heart, "Am I an inventor or an engineer?"

"Or, should I have my employees call me Engineer Xu in the future?"

"But that's Old Xu's title."

On the other side.

The engineers had already dismantled the light tank chassis, and around them were piled up turrets, machine guns, complete fire control systems, ammunition racks, automatic loaders, and so on.

Seeing this scene, Xu Fei first opened ten model slots of Mechanical Three Kingdoms, then took out his phone, contacted Old Xu, and told him to inform the buyer that the tracks and chassis would arrive by noon the next day.

Then he dialed the number left by the old man from the military department, telling him that he had a diesel engine that matched the technology transferred last time, which should be beneficial for the military department to understand its construction and principles. The internal price was 5 million dollars.

After finishing his work, he let the engineers continue to dismantle the light tank and arranged for 50 military dogs to patrol day and night.

By the early hours of the morning, he had obtained twenty sets of infrared halogen lamps and made twenty electric heaters. Only then did Xu Fei return to the Yellow Mud Hillock Electric Fan Factory with Da Ma.

He asked Lou Xiaohu to distribute the heaters to the workshop, office, and security booth.

After testing them for a while, if there were no problems, he would expand production and also equip the dormitories and toilets.

Xu Fei was planning to go straight back to the dormitory, but he noticed that the lights were still on in the office floor of the design company.

Thinking of the finalized Tianyin Cai Wenji, he immediately found Tang Mo.

"Little Tang, have you finished changing the music of the music box as I asked?"

"The music department said they can't change it. Cai Wenji is paired with the Eighteen Beats of a Nomad Flute, which represents Wenji returning to the Han. If you want a festive song, it's better to pair it with Wei Wu Cao Cao."

"What should Wei Wu Cao Cao be paired with?"

"Sister sits at the bow of the boat."
