Chapter 349 From then on, there was no more resentment between the uncle and nephew.

Li Jiajun sighed.

Holding this ordinary-looking fire pistol in his hand, he felt a sense of defeat.

This clever trick of using drone technology for a "dimensionality reduction strike" seemed far too weak in the face of an actual fire.

That pitiful amount of fire extinguishing agent had no substantial effect whatsoever.

He turned around.

With heavy steps, he left the backyard clearing that served as a testing ground.

Crossing the cement road of the factory area, he returned to the office building in front of the main workshop.

He pushed open the office door.

Big Hammer was sitting on a small stool in the corner, looking distressed as he studied the blueprints for the large equipment.

Li Jiajun walked to the wide desk and casually tossed the failed Parent-Child Firefighting Pistol onto the tabletop.

He pulled out the executive chair and sat down.

"Big Hammer."

Li Jiajun cleared his throat and began to arrange the upcoming work.

He pointed at the blueprints in Big Hammer's hands.

"That little pistol won't work; the fire extinguishing efficiency is too low."

"Stop worrying about that little toy for now."

"Follow the blueprints in your hand and go down to the workshop to keep an eye on things."

"Get the prototypes for those large pieces of equipment produced first."

Hearing this, Big Hammer looked up at the parameters on the blueprints, which were marked with tracks, armor, and a ten-kilometer range.

His mouth twitched, and he was speechless.

However, he didn't dare to argue and could only nod repeatedly in agreement.

Li Jiajun picked up the teacup on the desk, took a sip, and continued to explain.

"After all, once we build this equipment, we'll still need Uncle Liu to test it later."

"To see if it can be promoted to various fire departments."

"Only when the higher-ups give their approval can we mass-produce this equipment and earn back the initial R&D costs."

Big Hammer left, looking like he wanted to say something but stopped himself.

...

Just as Big Hammer had left the office.

The office door hadn't even fully closed yet.

The phone on the wide desk suddenly vibrated, followed by a crisp ringtone.

Li Jiajun put down his teacup and looked down.

The phone screen was glowing.

The name on the caller ID was indeed Liu Jianguo.

Li Jiajun raised an eyebrow.

Speak of the devil, and he shall appear.

He didn't hesitate, immediately picking up the phone and pressing the answer button, holding it to his ear.

"Hello, Uncle Liu," Li Jiajun greeted in a relaxed tone.

As soon as the call connected.

Liu Jianguo's somewhat anxious voice came through the receiver.

Liu Jianguo was currently sitting in his office in Beijing.

He had previously made a formal guarantee to the Old General that this time would be absolutely safe and would definitely solve the fire department's pain points.

But the Old General's doubtful tone before hanging up had left him feeling a bit uncertain.

So he asked impatiently:

"Little Li."

"How is the upgrade for that fire equipment going?"

"Have you found any breakthroughs?"

...

Hearing this barrage of questions.

Li Jiajun leaned back in his chair, a confident smile appearing on his face.

He immediately reached out his right hand and patted his chest, making a muffled "thump-thump" sound.

He said into the phone with absolute certainty:

"Uncle Liu, you're being too formal."

"Is there anything you need to worry about when I'm handling things?"

"I guarantee you, everything is being done exactly according to your requirements!"

"I've come up with perfect solutions for every single pain point!"

...

Hearing this guarantee on the other end of the line, Liu Jianguo's heart settled a bit.

He immediately asked Li Jiajun to describe the specific equipment in detail.

Then.

Li Jiajun began to briefly introduce his several newly finalized fire equipment designs.

He twirled a pen between his fingers with one hand.

He described them solemnly, though his tone carried a hint of showing off.

"Uncle Liu, listen closely."

"First is the issue of firefighters' physical strength."

"To solve the strength issue, I specifically designed a metal skeleton that provides hydraulic assistance."

"Once a firefighter puts on this skeleton, they can not only run like the wind but also easily carry over a hundred pounds of rescue equipment."

Liu Jianguo nodded repeatedly on the other end, feeling that this approach was the perfect remedy.

Li Jiajun paused and continued.

"Next are the pain points of ultra-high-rise buildings and long-range fire extinguishing."

"To solve the long-range issue, I designed a shoulder-mounted large tube that can fire ten kilometers."

"Firefighters don't even need to get near the fire; they can stand in a safe zone further away with the tube on their shoulder."

"Just aim at the fire source and launch the fire extinguishing shell directly."

Hearing "fire from a distance" and "shoulder-mounted large tube," Liu Jianguo thought that while the distance sounded quite far, he didn't overthink exactly how far it was.

He simply felt that the boy had been quite thorough in his considerations.

Seeing that Liu Jianguo had no objections, Li Jiajun spoke with even more enthusiasm.

"Then there's the response to extreme environments like chemical plant explosions."

"Ordinary fire trucks can't get in, and tires are easily punctured by debris."

"So to solve the harsh environment issue, I built a tracked vehicle with tracks and thick armor."

"This vehicle is not only crush-proof and explosion-proof but also equipped with a high-horsepower clearing blade, allowing it to move over ruins as if on level ground!"

"Finally!"

Li Jiajun raised his volume and threw out his most satisfying chemical fire extinguishing concept.

"To deal with those massive, spreading walls of fire."

"To solve the fire at its source, I've created a fire extinguishing shell..."

"Once this shell is fired, it can cut off the oxygen supply."

"Without oxygen as an accelerant, no matter how big the fire is, it will be extinguished on the spot!"

...

Li Jiajun reported his R&D results passionately over the phone.

When expressing himself, his wording leaned heavily toward fire rescue.

Meanwhile, Liu Jianguo, in his office at a certain Military Industry Department in Beijing,

Because his mind was filled with the preconceived notion of "fire equipment,"

Just listening to Li Jiajun's words,

Liu Jianguo felt it was all very good.

He felt these devices could not only completely solve the rescue pain points he had raised,

But more importantly, these things sounded like tools for carrying items, spraying from a distance, and driving over ruins.

There didn't seem to be anything that could be requisitioned.

However.

As Liu Jianguo held the phone to his ear, his brow furrowed slightly.

He couldn't help but feel that Li Jiajun's descriptions of the equipment sounded a bit strange.

Liu Jianguo shook his head, suppressing that slight sense of oddity.

He felt that as long as these devices could safely extinguish fires, nothing else mattered.

Finally.

Liu Jianguo leaned back in his executive chair and expressed his satisfaction happily to the other end of the line.

"Not bad, not bad."

"Little Li, your efficiency certainly didn't disappoint me!"

He felt that from now on, there would be no more grudges between uncle and nephew, as he had finally pointed the boy in the right direction.
