National Survival: I Supported the Dragon Nation by Hunting Dinosaurs

After riding Cangyu far from the camp, Zhang Li took off rapidly under Leng Feng's envious gaze!

The wind was howling like thunder.

Azure Feather's wings sliced ​​through the thin, cold air, each flap accompanied by the sound of muscle fibers taut.

Zhang Li lay on the dragon's back, a thin layer of white frost on his eyelashes.

The forest below had turned into a dark green carpet, and the rivers on the ground meandered like silver threads.

At the edge of the field of vision, the enormous arc that stretches across the heavens and earth is breathtaking—that is the curvature of the blue planet.

Inside the live stream, the camera swayed according to Zhang Li's perspective.

Looking at the height on the screen, Wang Bingbing's voice tightened slightly: "Ladies and gentlemen, is this the skyline of the prehistoric world? This pure, unpolluted clarity is simply a miracle!"

This extreme magnificence triggered an explosion of praise in the comments section.

"That's real aerial photography! What garbage are those drone shots?!"

"Where is Li Shen heading? This direction... seems to be that main peak that's always shrouded in clouds?"

Twenty minutes later.

The previously calm airflow began to turn violent.

Azure Feather's wingtips began to frequently adjust their angles to counteract the turbulence.

Ahead, a black mountain peak, sharp as a sword, suddenly appeared.

Unlike the lush green mountains around it, this mountain is gray-green all over, with its peak covered in snow. The black, white and green colors intertwine, making it very unique!

"Get out of here."

Zhang Li patted Cang Yu's neck.

Azure Feather folded its wings and landed steadily on the winding mountain ridge road.

The altitude here is extremely high, and the thin air makes breathing somewhat rapid.

Zhang Li jumped off the dragon's back and took out a pottery jar from his spatial storage.

This is the river water he collected in the rainforest.

"Splash!"

He poured the water onto the black boulder at his feet.

A bizarre scene unfolded.

Instead of flowing downhill due to gravity, the water gathered into thin streams and stubbornly "climbed" towards the top of the mountain!

Inside the live stream, Wang Bingbing instinctively asked, "Director? Is the footage reversed? Why is the water... flowing uphill?"

In the studio, Professor Li's fingers tapped unconsciously on the table.

"It's not played in reverse, and it's not magic."

Professor Li's voice was deep and carried an academic rigor.

"This phenomenon also exists in some extreme geological environments on Earth, such as the famous 'gravity hill.' But the phenomenon here is much more intense."

"Water is a diamagnetic substance, but when it contains a large amount of ferromagnetic impurities, or when there is an extremely strong non-uniform magnetic field on the Earth's surface, the magnetic force exceeds the gravitational component in a local vector."

Simply put, this mountain is a giant, exposed magnetic pole.

"Magnetic fields counteract gravity."

Professor Chen was also observing the rock texture under Zhang Li's feet.

"Look at the fault lines in those rocks!"

"This isn't ordinary magnetite. Look at its distinctive greasy luster, and the accompanying signs of serpentinization!"

"Grayish-green, strongly magnetic, with olivine present..." Professor Chen took a deep breath.

"This is 'gray-green magnetite'! An extremely rare cobalt-nickel magnetite symbiotic aggregate!"

Professor Li picked up the conversation, seemingly lost in thought:

"That explains it. If it's high-purity cobalt-nickel magnetite, its magnetic saturation strength far exceeds that of ordinary magnetite."

Zhang Li probably intends to mine these ores for a sacrificial offering? After all, this rare metal ore is definitely not low-grade.

But a hint of doubt flashed in his eyes:

"But... is it just a sacrifice? Although it's scarce on Blue Star, this mineral hasn't disappeared. If it's just for exchanging for supplies, the cost-effectiveness doesn't seem worth the risk of oxygen deprivation at high altitudes to come here."

On the screen.

Zhang Li watched the water droplets climbing towards the mountaintop, and his all-knowing eye revealed...

[Cobalt-nickel magnetite: Main components: Fe (68%), Ni (12%), Co (8%), trace lanthanide elements..., naturally ordered magnetic domains.]

"This level of purity..." Zhang Li muttered to himself, his voice broken by the strong wind, "It's not only possible to make cannon barrels, but even... it's not impossible to make radar and tracking missiles."

His voice was clearly heard by audiences around the world.

The live stream chat exploded instantly.

"???"

"What did I just hear? Radar? Missiles?"

"I can believe the gun barrel; that's blacksmithing. But radar and missiles are electronic engineering! Where is he supposed to find chips in this desolate wilderness?"

Image caption: [Impossible, absolutely impossible.jpg]

In the studio, Wang Bingbing was stunned for a moment, then looked awkwardly at the two professors: "Professor Li... Zhang Li was just talking about... missiles?"

Professor Li's facial expression was quite interesting.

That was a complex expression—reason telling him "this is absurd," but emotionally anticipating being proven wrong.

"Making cannon barrels is theoretically entirely feasible."

Professor Li quickly regained his professional demeanor.

"The biggest problem with conventional pure iron or cast iron gun barrels is their poor heat resistance."

The temperature at the moment of gunpowder explosion is extremely high. After firing only a few rounds, the cannon barrel will soften, deform, or even explode. This is why ancient cannons had such a short lifespan.

"But if you add nickel and cobalt, the situation is completely different. Nickel can significantly improve the toughness and ductility of metals, preventing the gun barrel from cracking under enormous chamber pressure; while cobalt..."

"That's the key to 'red hardness.' Cobalt alloys can maintain extremely high hardness even at high temperatures."

Professor Li then changed the subject: "However, radar and tracking missiles are another matter..."

He shrugged and said with a wry smile, "Unless Zhang Li can carve a lithography machine out of stone, it's just a pipe dream."

However, Professor Chen added quietly, "Old Li, don't be so sure of yourself. This kid's brain works differently than normal people."

Professor Li was taken aback, then chuckled: "That's true. Although science tells me it's impossible, I... I'm damnably hoping for it."

on the screen.

Zhang Li took out his entrenching tool, aimed it at the glowing rock beneath his feet, and began to chisel it away fiercely.

"clang--!"

The rocks here are much harder than Zhang Li had expected.

The entrenching tool's blade cuts into the ore, sending a strong tremor back to the arm.

"Clang! Clang! Clang!"

Zhang Li was like a tireless machine, each swing landing precisely on the same spot.

......

Azure Feather lay in a sheltered spot, its massive head buried under its wings.

It is extremely unsuitable for this environment filled with magnetic field interference.

For creatures that rely on geomagnetic navigation, this place would keep them in a constant state of dizziness and anxiety.

"Bang!"

A large chunk of rich ore, weighing at least fifty kilograms, was pried off.

Zhang Li casually put it into his storage space.

Just then, a crackling sound of electricity filled the air.

"Sizzle..."

Suddenly, a bluish spark flew from the tip of the entrenching tool in Zhang Li's hand.

That is the St. Elmo Fire (St. Elmo Fire is not fire, but a cold light coronal discharge phenomenon under the strong electric field of a thunderstorm, caused by the ionization of the air in the field due to the strong electric field during the thunderstorm).

Tip discharge phenomenon.

Zhang Li felt a tingling sensation on his scalp; his normally docile hair was now standing on end.

This is a sign that the electrostatic field strength has exceeded the limit.
