386: They exchanged a smile, their eyes revealing everything.

"Kill—!!!"

At the Duke of Black Iron's command, hundreds of heavy infantry surged into the "Gilded Rose" inn like a black tide, howling as they raised their enchanted shields.

Heavy combat boots stepped on the wooden floor, making an ear-piercing cracking sound.

The entire building was trembling.

"Brother Chen! They actually dare to charge!"

Although Wang Peng (Fatty) shouted in fear, he tightly gripped the tactical dagger used for cutting dragon meat and blocked the stairs.

"These blind hillbillies, they even dare to provoke you? Fat Master will fight them to the death!"

"Fight for what?"

Lu Chen stood at the edge of the terrace, still holding that glass of rum.

He looked at the soldiers swarming in like ants below, his face showing not even a ripple of emotion.

He just turned his head and looked at Su Qingying beside him.

No words were needed.

Just an exchange of glances.

Su Qingying gently closed the data pad in her hand.

She looked up, and in those cold eyes, countless complex calculation formulas were flashing.

That was the composure of the "Dean of the Academy of Sciences of Myriad Realms," and an absolute mastery over truth.

"Black iron alloy density 7.8, carbon content 2%."

"The enchanted rune energy circuits are crude, belonging to a low-frequency oscillation structure."

Su Qingying's voice was very soft, but amidst the noisy shouts of killing, it clearly reached Lu Chen's ears.

"Resonance frequency: 4277 Hertz."

"Sound pressure threshold: 150 decibels."

"Understood."

The corners of Lu Chen's mouth curled up slightly.

He tilted his head back and drained the strong liquor in his glass.

Then.

He fished out that so-called "Solar Divine Artifact"—the [High-intensity Flashlight]—from his pocket.

Not only that, he also pressed an inconspicuous red button on the flashlight's handle.

That was something the engineering department had added to clean barnacles off the spaceship's hull—the [Ultrasonic Descaling Module].

"Fatty, cover your ears."

Lu Chen reminded him flatly.

"Huh?" Wang Peng was stunned, but out of blind trust in Lu Chen, he immediately dropped his dagger and covered his ears tightly.

The next second.

Lu Chen pointed the head of the flashlight at the group of soldiers downstairs.

But he didn't turn on the light.

Instead, he turned on the vibration.

"Buzz—"

At first, it was a very low hum, so low that human ears couldn't hear it at all.

But the air began to twist eerily.

The wine glass on the table shattered instantly.

Then.

"Crack! Crack! Crack!"

The heavy soldiers charging at the very front downstairs suddenly stopped in horror.

They felt the armor on their bodies heating up and throbbing, as if it had come to life!

"My... my breastplate is shaking!"

"My helmet! The helmet is cracking!"

"Ah! So hot! It feels like it's on fire!"

"This is resonance."

Lu Chen stood on high like a conductor, gently turning the power knob of the flashlight.

"When the frequency of sound waves matches the natural frequency of a substance..."

"Even the hardest steel..."

Lu Chen suddenly turned the knob to the maximum!

"...will be like a crisp cracker..."

"...and shatter!"

"Bang—!!!"

A uniform crisp sound echoed throughout the entire Black Iron City.

Under the Duke's horrified gaze.

The armor on his most elite three hundred heavy infantrymen...

...exploded.

It wasn't blown apart by gunpowder.

Instead, it disintegrated on its own into countless fingernail-sized fragments!

It was as if all their defenses had been instantly stripped away!

The soldiers who had lost their armor stood there dumbstruck, wearing only thin shirts, holding spears that were also broken into several sections, looking like shucked lobsters.

As the wind blew.

There was dead silence.

"Wh-What kind of magic is this?!"

The Duke of Black Iron, riding on his horse, was so scared he almost fell off.

"No mana fluctuations! No incantations! He didn't even lift a hand!"

"Is this an instant-cast Forbidden Spell?!"

"Forbidden Spell?"

Lu Chen turned off the flashlight and tossed it to Wang Peng.

He leaned against the railing and turned to look at Su Qingying.

At this moment, Su Qingying was also looking at him.

Their gazes met in mid-air.

Su Qingying smiled.

It wasn't a polite smile, but a heartfelt one with a hint of small pride.

As if saying: Look, my calculations never go wrong.

Lu Chen also smiled.

He reached out and helped her tidy a stray hair at her temple.

His eyes were full of doting.

As if saying: Yes, perfect coordination.

Everything was in their eyes.

No system needed, no divine power needed.

As long as you are by my side, as long as your brain is still functioning.

All the rules of this world are just playthings in our hands.

"Cough, cough..."

Wang Peng let go of his ears and looked at the "naked" soldiers downstairs, unable to resist breaking the pink bubbles filling the screen.

"Um, Brother Chen, Sister-in-law."

"Although I really don't want to disturb your public display of affection..."

"But..."

Wang Peng pointed at the Duke downstairs, who had already drawn his sword and was flying into a rage from shame.

"That old guy doesn't seem convinced yet."

Sure enough.

Although the Duke of Black Iron was frightened by this "Armor Shattering Technique," his dignity as a regional hegemon wouldn't let him retreat.

"Witchcraft! This must be witchcraft!"

The Duke brandished his longsword and roared hoarsely.

"Infantry, fall back!"

"Archers! Mage Corps! Go!"

"Long-range coverage! Level that building for me!"

"Whoosh, whoosh, whoosh—"

Hundreds of burning magical arrows and a dozen huge fireballs pierced the night sky, whistling toward the inn terrace!

"This is a bit unsportsmanlike."

Lu Chen shook his head.

He had no intention of dodging.

Su Qingying, however, moved first.

She took out several silver metal discs from her pouch.

Those were the [Portable Force Field Generators] from the spaceship name.

"Wind speed level 3, southeast."

"Gravity coefficient 12."

"Fireball energy structure: Unstable."

While Su Qingying whispered the data, she threw the discs out like frisbees.

"Lu Chen, three o'clock direction, detonate."

"Copy that."

Without even looking, Lu Chen picked up a peanut from the table and flicked it with his finger.

"Phew!"

The peanut whistled through the air and accurately hit one of the discs flying in the sky.

"Zzz—"

The disc activated instantly.

A blue anti-gravity force field suddenly expanded in mid-air!

Under the influence of this force field, the whistling arrows and fireballs took an eerie turn.

They were like being grabbed by an invisible giant hand, drawing a perfect "U" curve in the air.

Then.

At an even faster speed, they returned the way they came!

"Holy crap?!"

The Duke below only had time to shout those two words.

"Rumble—!!!"

A rain of fire accurately covered the Duke's guard formation.

Explosions, screams, and the neighing of horses instantly blended together.

The entire street turned into a sea of fire.

In the smoke.

Lu Chen and Su Qingying still stood on the terrace.

Their clothes fluttered, and they were unstained by a speck of dust.

"What do you say?"

Lu Chen turned to look at Wang Peng, "Convinced this time?"

"Convinced! Absolutely convinced!"

Wang Peng gave a thumbs up, "Brother Chen, Sister-in-law, you guys aren't fighting a battle."

"You're giving the natives a physics lesson!"

Lu Chen smiled.

He walked to the railing and looked at the Duke of Black Iron below, who was covered in soot and had a crooked helmet.

"Hey! You on the horse!"

Lu Chen shouted.

The Duke looked up, his face charred, his eyes full of terror.

This time, he was truly afraid.

This was not a battle on the same dimension at all!

"Want to continue?"

Lu Chen shook a handful of peanuts in his hand.

"I've got plenty of ammunition here."

"How about I give you a physics version of 'Ten Thousand Arrows Piercing the Heart'?"

"No... no more fighting!"

The Duke threw away his broken sword, rolled off his horse, and knelt on the ground.

"Surrender! I surrender!"

"Your Excellency is a god! A true god has descended!"

"Black Iron City is willing to submit!"

Looking at the soldiers kneeling in a row.

Lu Chen turned around and met Su Qingying's gaze again.

A trace of helpless laughter flashed in both their eyes.

"It seems."

Lu Chen shrugged.

"Our 'Dragon Slaying Inn' hasn't even opened for business yet."

"And we're already going to have a side job as 'City Lord'."

Su Qingying gently took his arm and rested her head on his shoulder.

"If we must, then we must."

"Coincidentally, I also want to see if the 'truth' of this magical world"

"can be derived and rewritten"

"by our 'formulas'."

Lu Chen gripped her hand tightly.

He looked up.

At those two purple moons.

"Alright."

"Then we'll start with this city."

"And engrave our names"

"onto the textbooks"

"of this universe!"
