Chapter 343 Perfect Train Extinguishing!

The sound of footsteps gradually fading away came from the corridor outside.

Li Jiajun withdrew his gaze and sat up straight again.

He reached out and adjusted the camera angle slightly, ensuring his energetic face appeared clearly in the center of his exclusive livestream room's screen.

The thousands of die-hard fans in the livestream room had just watched the factory director issue orders, and the bullet chat was scrolling rapidly at this moment.

"The Main Streamer's efficiency is top-notch; another blueprint has been sent down."

"I wonder how impressive that long-range fire extinguisher from just now will be once it's built. The name sounds domineering."

"Gaining new insights by following the factory director. Looking forward to the real thing!"

...

Looking at these bullet chat messages, Li Jiajun smiled with satisfaction.

He felt that livestreaming for these 'old irons' who understood him and civil equipment was a form of enjoyment.

There were no sarcastic comments accusing him of manufacturing weapons, nor were there people threatening to report him at every turn.

He reached out and pulled the notebook filled with pain point requirements toward him.

After solving the issues of firefighter stamina and long-range firefighting, the next challenge was even more daunting.

His gaze fell on a line of words heavily circled in black ink in the notebook.

[Extremely Harsh Environments]

Looking at these words, the smile on Li Jiajun's face gradually faded, and his expression became solemn.

He tapped his finger lightly on the desk, producing a crisp sound.

"family, the next thing we're going to tackle is a tough nut to crack."

Li Jiajun spoke into the phone camera with a serious tone.

"The pain point Uncle Liu mentioned to me is very realistic and very cruel."

"Think about it, if a chain of explosions occurred at a large chemical plant, what would the scene look like?"

Without waiting for the bullet chat to answer, he began the description himself.

"The ground would be covered in burning building debris."

"Collapsed workshops, broken concrete pillars, and rebar as sharp as knives lying scattered all over the ground."

"A standard fire engine's tires would burst immediately upon driving over them; it simply couldn't get in."

"If the vehicle can't get in, what about having people walk in wearing protective suits?"

Li Jiajun shook his head, a trace of pity showing on his face.

"In that kind of environment, it's practically impossible for a person to move a single step."

"Even with exoskeletons to save stamina, there are concrete slabs that could fall from overhead at any moment, small explosions that could happen nearby anytime, and leaked toxic gases."

"Any one of those things could easily take a firefighter's life."

Listening to Li Jiajun's detailed and vivid description,

The atmosphere in the livestream room grew heavy.

Although the die-hard fans were military novices, they were all flesh-and-blood ordinary people who could naturally sense the terror of such a hellish fire scene.

"It's too hard. In this situation, can we only wait for the fire to burn itself out?"

"Yeah, this is too dangerous. Human lives are at stake."

"Factory Director, is this problem beyond the scope of the curriculum?"

...

Li Jiajun looked at the bullet chat on the screen.

He gritted his teeth, his stubborn streak being provoked.

How exactly could one move as if on level ground in a fire scene full of explosives and collapsed ruins?

He sat in his large executive chair, brows tightly furrowed, sinking into deep worry.

He felt there must be a way to solve this problem.

To open up his train of thought, he gripped the mouse and skillfully opened several video websites on his computer browser.

He began casually searching for various documentary videos of post-disaster reconstruction and large-scale debris clearing.

He hoped to find inspiration from the working methods of other heavy machinery.

The mouse wheel kept scrolling as videos were clicked open and then closed.

After watching for a while, his gaze was suddenly drawn to an engineering video with a low view count.

He clicked it to full screen.

The video footage was a bit shaky, clearly filmed from a distance with a mobile phone.

It showed the ruins of an unfinished building that had just been demolished by directional blasting.

A massive amount of rebar and concrete fragments were piled up like mountains, forming a man-made harsh terrain.

In the center of the frame, a massive yellow crawler bulldozer was emitting a deafening roar.

The diesel engine was spewing black smoke.

The bulldozer was struggling to push away tons of construction waste, attempting to force a path through the ruins.

Li Jiajun's eyes were fixed on the bottom of that bulldozer.

He saw those wide metal tracks moving without the slightest hesitation as they rolled over sharp rebar and jagged rocks.

The tracks' massive contact area and hard material allowed the bulldozer to perform exceptionally steadily on these ruins, completely free from the risk of ordinary tires being punctured.

'Tracks... this is good stuff.' The thought surfaced in his mind.

Just as he was about to continue digging deeper into the idea of tracks,

A thrilling accident suddenly occurred in the video.

As the bulldozer pushed away a massive piece of load-bearing wall wreckage, it seemed to disrupt the balance of the ruins above.

Terrified shouts could be heard in the video.

Immediately following,

A concrete block about half the size of a family car, mixed with twisted rebar, suddenly fell from the top of the ruins over ten meters high.

The giant rock, accompanied by the whistling of the wind, struck the top of the bulldozer's cabin with pinpoint accuracy.

"Bang!"

A dull, heavy thud came through the speakers.

The bulldozer, which was in the middle of exerting force, was hit so hard that its entire body suddenly sank downward.

Looking at the cabin again,

The thin iron sheet of the bulldozer's cabin, intended only to shield from wind and rain, was as fragile as tissue paper against the impact of the giant rock.

In an instant, a shocking crater was smashed into the roof, which caved in deeply.

Glass shattered and flew.

The metal frame of the cabin was smashed out of shape.

The video footage shook violently as the person filming shouted and ran over to help.

Fortunately, after flattening the roof, the rock slid to the side and didn't completely crush the cabin.

The driver, face covered in blood, was pulled out of the deformed door by coworkers using all their strength, nearly losing his life in those ruins.

...

Watching that heart-pounding scene on the screen,

Li Jiajun, sitting before the computer, felt his scalp tingle.

Too dangerous.

If this wasn't ordinary debris clearing, but a chemical plant fire scene where secondary explosions could happen at any time,

And if it wasn't just rocks falling, but also burning tanks,

Then sending in this kind of ordinary engineering vehicle would be like delivering a coffin for the firefighters.

Stimulated by this intense sense of crisis,

Li Jiajun's eyes instantly lost focus, becoming hollow.

All surrounding sounds, including the hum of the computer case fans, quickly receded from his perception.

He once again entered that state of epiphany where one forgets both self and the world.

His brain, like an ignited engine, began to run frantically.

His lips moved slightly as he began to analyze in a low murmur.

That rapid-fire voice traveled through the microphone and clearly reached the ears of the thousands of die-hard fans in the livestream room.

"To force a path through extreme ruins, ordinary tires absolutely won't work."

His speech was extremely fast, as if racing against something invisible.

"Tracks are the only option."

"But the ground temperature in a fire scene is extremely high. Metal tracks conduct heat too quickly. Heat-resistant rubber-padded tracks must be used to increase grip while insulating against the heat."

Following his deduction, a rugged chassis outline gradually emerged in his mind.

"And that cabin..."

Li Jiajun closed his eyes, brows tightly knit, his voice echoing in the office.

"The ordinary thin iron sheet of a bulldozer is simply a joke."

"It can't withstand the shockwaves from explosions, and it certainly can't stop heavy objects falling from high altitudes."

"To protect the people inside, the entire vehicle body must be encased."

"Change it to a fully enclosed structure!"

His hands gestured unconsciously in the air, as if sculpting a piece of art.

"Single-layer steel plates aren't enough; ultra-thick composite armored steel plates must be used."

"And it can't be a straight up-and-down design."

"If it's a vertical steel plate, it will absorb the full force of an impact."

"It must have an incline!"

"Make the armor sloped. This way, when a falling object hits or an explosion shockwave sweeps over, a large part of the force can be deflected by the inclined surface. This is called sloped armor deflection!"

Li Jiajun's analysis grew deeper and deeper, with various hardcore protection concepts constantly popping out of his mouth.

The die-hard fans in the livestream room listened in a daze. Although they didn't quite understand things like sloped armor or composite armor, they all felt that the factory director's current appearance was terrifyingly professional.

"What if the road ahead is blocked?"

Li Jiajun's deduction continued.

"Ordinary bulldozer blades can't move tangled rebar and large load-bearing walls."

"To clear obstacles, a high-horsepower Demolition and Clearing Blade must be added to the front of the vehicle!"

"Ideally with hydraulic cutting capabilities to directly snip through blocking rebar!"

One by one, harsh survival conditions were rapidly transformed into mechanical design parameters in his mind.

...

Just as the sparks of his thoughts collided most fiercely,

Ding, [You watched a thrilling video of debris clearing, combined fluid mechanics, track transmission principles, and armor protection theory, and fell into deep thought...]

Ding, [You have instantly understood the mysteries of all-terrain heavy protective vehicles! You have gained an epiphany in All-terrain Heavy Crawler Armored Fire Truck technology!]

Accompanying the crisp notification sound in his mind,

All technical barriers were completely shattered at this moment.

A flood of knowledge regarding composite armor ratios, torsion bar suspension systems, and high-horsepower diesel engine blueprints instantly surged into the depths of his memory.

Li Jiajun snapped his eyes open.

The fanatical light unique to inventors flickered in his eyes.

He grabbed the black marker from the desk and pulled over a brand-new, massive sheet of drawing paper.

Without any hesitation,

The tip of his pen hit the paper, producing a series of rapid and continuous rustling sounds.

He smoothly sketched out the outline of a massive, heavy vehicle filled with the aesthetic of steel violence from his epiphany.

At the bottom were wide, sturdy, heat-resistant rubber-padded tracks with several pairs of road wheels, looking as if they had the grip to crush anything.

Above the tracks was a fully enclosed vehicle body.

He didn't draw a boxy cabin but instead followed the earlier idea of sloped armor deflection, drawing heavy, inclined armor.

The entire front and sides of the vehicle presented a flat and angular design specifically intended to deflect shockwaves.

Right at the front of the vehicle,

He specifically emphasized with his pen, drawing a high-horsepower Demolition and Clearing Blade equipped with serrations and hydraulic arms.

On the internal cross-section of the vehicle body,

He also meticulously drew a complex self-circulating air system and filtration devices, heavily labeling them next to it: [Anti-toxic Gas Seepage Design].

Finally, the most crucial step.

This was equipment meant for firefighting; how could it work without something to spray water?

With a flick of his wrist, on the top of the fully enclosed vehicle body—on a circular structure similar to a base—

He drew a base that could rotate three hundred and sixty degrees.

Then, extending from the base, he drew a thick, long metal pipe with an astonishing caliber.

To indicate the purpose of this pipe, he drew a lead line next to it and wrote: [High-pressure Injection Pipe, capable of spraying various decontamination fluids and water jets].

...

A few minutes later,

The final stroke fell.

Li Jiajun tossed the marker aside and leaned back in his chair, letting out a long sigh of relief.

He looked at the drawing on the desk, the ink still wet.

The steel monster on the paper radiated an indestructible sense of oppression from head to toe.

The sloped armor, the wide tracks, and that massive pipe on top.

No matter how you looked at it, it exuded a fierce aura capable of crushing any obstacle into powder.

But in Li Jiajun's eyes, this wasn't a killing machine at all.

He felt this was the ultimate rescue equipment born to defy the Grim Reaper.

"Too perfect."

He looked at the drawing, speechless—speechless at his own talent.

He couldn't help but murmur in praise.

"Only a design like this can move freely in the explosion ruins of a chemical plant."

"Maximum protection, tracks to lead the way, unafraid of impacts, unafraid of poison."

"This can absolutely protect firefighters' safety from all angles in the harshest fire scenes!"

The more Li Jiajun looked, the more he felt his design was a work of genius.

He felt that the Experts who were being stifled by imported high-end fire trucks still had too conservative a mindset.

Why must a fire truck have a truck chassis?

In such life-and-death environments, taking protection to the extreme is the real answer.

He couldn't wait to share his great invention with others.

Li Jiajun carefully picked up the drawing.

He stood up and brought the structural diagram of this "perfect fire truck" directly in front of the phone camera.

"family!"

Li Jiajun's tone was filled with pride and glory.

"Look at this heavy firefighting equipment our Li Family Toy Factory is about to launch!"

"With this, firefighters will never have to risk their lives rushing into ruins that could explode at any moment!"
