The tyrannical father was so intimidated when his own daughter was found during the raid.

Su Yaoyao picked up the wolf-hair brush, which was a bit too big for her.

With short legs, I walked to the huge whiteboard standing upright.

"Swish, swish, swish."

The little girl's wrist hovered in the air, and her brushstrokes flowed like dragons.

Under the watchful eyes of everyone, she wrote a long string of strange symbols on the whiteboard.

All in one go.

Everyone in the hall craned their necks, staring curiously at the whiteboard.

Even the head of the delegation, who was still questioning his life and sitting on the ground, couldn't help but look up.

On the huge whiteboard, there was a formula that was completely incomprehensible.

In front is an elongated "S" shaped pattern.

Following this was a bunch of crooked, illegible foreign symbols.

There's also a horizontally inverted "八" character in the middle, which is extremely bizarre.

The scholars of the Great Abyss Kingdom rubbed their eyes, their faces full of confusion.

"What is this? Could it be a Taoist rain-praying talisman?"

"I have read all the classics in the world, and I have never seen such writing before!"

The mathematics masters of the Central Continent delegation also gathered around.

They stared at the whiteboard, their brows furrowed, their eyes practically bulging out, yet they couldn't recognize a single symbol.

Su Yaoyao casually tossed the brush back into the brush washer.

It makes a crisp "ding" sound.

"You're making a fuss over nothing."

Su Yaoyao clapped her little hands, her childish voice mocking.

"Listen carefully, this is advanced arithmetic—calculus."

"It contains the profound principles of the universe, encompassing both the infinitely large and the infinitely small."

"It calculates the limit of the area under the curve."

Then, Su Yaoyao turned her head and snapped her fingers at Su Jin, who was standing to the side.

"Brother Crown Prince, bring up the toys I prepared."

"Let our distinguished guests from Central Plains have a good look at us!"

Su Jin was still emitting a faint pink glow.

But that doesn't stop him from being his sister's number one henchman.

He sneered and turned to carry a heavy wooden box from the back of the main hall.

"Splash!"

Su Jin dumped everything from the wooden box onto the mahogany table in front of the delegation leader.

Those were a thousand small pieces of wood, cut extremely evenly.

Each piece is exactly the same size and thickness, with uneven grooves on the edges.

The most problematic thing is that these thousand small pieces of wood are all painted with pure white varnish without any impurities.

There isn't a single ink dot or a trace of texture on it!

It reflects light in the candlelight!

"This is a 1000-piece, plain white jigsaw puzzle."

Su Yaoyao crossed her arms over her chest.

"The difficulty of piecing it together is comparable to restoring a shattered painting."

"But because there are no pattern cues, you can only bite together based on the slight differences in shape."

Su Yaoyao reached out and grabbed the jade box containing the Xuanbing Stone from the table.

She coldly looked down at the Central Plains delegation, and stated her terms with conviction.

"Solve the calculus formulas and put together the whiteboard puzzle."

"If you people of Zhongzhou can accomplish this tonight, I, the Crown Princess, will return this Xuanbing Stone to you intact!"

"If you can't do it, you'd better immediately tuck your tails between your legs and get back to Zhongzhou from the territory of the Great Abyss Kingdom!"

Domineering!

Arrogant!

Treat them as they treat you!

The generals of Dayuan Kingdom were so excited that they wished they could kowtow to the Crown Princess on the spot.

Su Zhen sat on the pure steel dragon throne, his mouth stretched almost to his ears with a grin.

No wonder he is my son!

His arrogant and domineering manner is just like mine!

The mission commander was so angry at these words that he trembled all over, his face turning pale and then red.

He scrambled to his feet, screaming like a cat whose tail had been stepped on.

"You little brat, how dare you presume there's no one capable in our Central Plains!"

"It's nothing but some strange tricks and random scribbles. Do you really think my great nation of Zhongzhou can't solve it?"

The delegation leader turned around and roared furiously at the scholars accompanying him.

"What are you all standing there for! Get them!"

"Solve this problem immediately, piece together this picture, and give that Great Abyss Demoness a good slap in the face!"

The number one mathematics master of the Central Continent Empire gritted his teeth and led several disciples to rush to the whiteboard.

The head of the delegation, along with several other civil officials, gathered around the pure white jigsaw puzzle.

This concerns the national system; it is a matter of utmost importance!

Ideal is full, the reality is very skinny.

The mathematics master stood in front of the whiteboard, holding the abacus in both hands, sweating profusely.

He attempted to understand calculus formulas using the oldest methods of exponentiation and abacus calculation from Central China.

"Infinity? Does the horizontally inverted 'eight' character represent infinity?"

"Since it's infinite, how can you possibly calculate a definite result?"

"Crackling! Crackle!"

The mathematical master's fingers moved frantically across the abacus, leaving afterimages.

He attempted to divide the curve infinitely and derive the limit of the integral using the most basic addition, subtraction, multiplication, and division.

However, no matter how he calculated, the numbers on the abacus kept getting bigger and bigger.

There is no end in sight.

"Impossible...this is impossible..."

Why, after the final division, is it both zero and not zero?

"If it's zero, why can it be divided? If it's not zero, why say it's infinitesimal?"

The mathematics master's eyes were bloodshot, and he was muttering incoherently and nervously.

Every time he tried to force himself to understand the logic of the formula, his brain felt like it was being hammered.

On the other hand, the situation of the envoy leader was ten times worse than that of the mathematics master.

A thousand pure white puzzle pieces gleamed with a blinding white light under the candlelight, a light that evoked despair.

There are no colors or lines.

This forced the team leader to compare the shapes of the edges piece by piece.

"This piece and this piece can be put together... wait! The slot on the right doesn't match!"

"Then let's change to this one! But that's not right either, the gap is too big!"

After less than a quarter of an hour of fighting, the commander and several civil officials were already feeling dizzy and lightheaded.

The overwhelming whiteness caused them severe visual fatigue and snow blindness hallucinations.

Everything they saw was a pure white expanse.

They even thought the wooden blocks had grown legs and were laughing at them.

The regimental commander scratched his head in frustration, turning his meticulously combed hair into a mess.

Time slips away, bit by bit.

Half an hour has passed.

The officials of Da Yuan Kingdom leisurely drank tea and ate snacks.

Su Zhen ordered someone to bring over a soft couch, and he lay half-reclined on it.

He watched with great interest as the group of people from Zhongzhou went mad.

"If the esteemed envoy from Zhongzhou cannot calculate it, please do not force yourself."

Su Zhen, holding his wine glass, mocked in a sarcastic tone.

"If you suffer a brain injury, I will have to send imperial physicians to treat you, which will cost a lot of money."

The generals of Da Yuan burst into laughter, their laughter like steel needles piercing the ears of the mission leader.

Just then, a particularly shrill scream suddenly erupted from in front of the whiteboard.

"I understand! I understand! It is both infinitely vast and infinitely small!"

The foremost mathematics master of Central China raised his hands, his eyes bulging outwards.

All the capillaries in the back of the eye ruptured, and the eyeballs were frighteningly red.

"puff!"

The mathematics master felt a sweet taste in his throat, and then gushed out a mouthful of blood like a fountain.

Crimson blood sprayed precisely onto the huge whiteboard in front of them, a shocking sight.

He looked as if all his bones had been drained, and his eyes rolled back on the spot.

With a "bang".

It fell straight backward.

He fainted and lost consciousness!

"A master! A master of mathematics!"

The Central Plains delegation was thrown into chaos, and their terrified cries echoed throughout the hall.

This scream became the final straw that broke the delegation leader's back.

He stared blankly at the whiteboard puzzle on the table, which hadn't even been pieced together with ten pieces, and his mental defenses crumbled.

The blinding white light transformed into an abyss, completely engulfing his reason.

"It can't be pieced together...it's simply impossible to piece together!"

This completely broke the regimental commander.

He held his head in his hands, his fingers gripping his hair.

A large handful of bloody scalp was ripped off.

"Ahhhhh!"

His knees buckled, and with a thud, he knelt heavily in front of the mahogany table.

Tears and snot smeared his once proud and arrogant old face.

He pounded the ground like a madman.

She burst into loud sobs, her voice as shrill as a pig being slaughtered.

The once arrogant Central Plains delegation suffered a complete and utter defeat.

Looking at the chaotic scene of the Central Plains delegation dancing wildly in the main hall.

Su Yaoyao gave a cold laugh and lost interest.

With such poor mental fortitude, how dare they come to Da Yuan Kingdom to act tough?

[They're really fragile.]

Su Yaoyao ignored the mission leader who was kneeling on the ground, weeping bitterly.

She happily hugged the jade box containing the Xuanbing Stone tightly to her chest.

Turning around, she nimbly slipped out of the Taiji Hall with her short, light legs.

They plunged headlong into the night.

[Fantastic! With this piece of mystic ice stone, the Gatling gun's blast-proof barrel can be assembled tonight!]

[Mom, my fear of insufficient firepower is cured!]

Su Yaoyao cheered excitedly in her heart and ran quickly towards the Cold Palace Arsenal.

The other side of the Taiji Hall.

The powerful minister and general Lin Zhenxiong sat at the head of the military officers.

He watched the farce of the Central Plains delegation with cold eyes, sneering disdainfully in his heart.

A bunch of idiots who can only talk big.

He was destined for mediocrity.

Lin Zhenxiong silently twirled the wine bottle in his hand, glancing at Su Zhen on the high platform with a sinister look in his eyes.

Go ahead and make a scene.

Go ahead and have a blast.

After a few rounds of drinks, the five hundred heavily armored lion dance troupe he had arranged in the palace would immediately begin their performance!

Meanwhile, at Black Wind Stronghold outside the city, the fine iron weapons he had painstakingly crafted and the ten cartloads of gunpowder were already in place.

As long as he smashes the cup as a signal, the Blood Droplets will coordinate from within and without to storm the palace.

Tonight, the kingdom of Da Yuan will be ruled by the Lin family!

Just as Lin Zhenxiong was immersed in his dream of ascending the throne.

A trusted henchman, disguised as a eunuch serving dishes, approached him with a terrified expression.

His confidant was covered in cold sweat, and his hands, holding the plate, trembled violently.

He used the act of pouring wine as a cover to lower his voice, his tone filled with despair.

"My lord...my lord! Something terrible has happened!"

Lin Zhenxiong frowned and scolded in a low voice, "What's the panic! Proceed according to plan!"

"No...that's not it!"

The confidant's voice, trembling with tears, came close to Lin Zhenxiong's ear.

"Black Wind Stronghold...is empty!"

Lin Zhenxiong paused in his hand holding the wine bottle, his eyes turning sharp.

"What did you say?"

The confidant was on the verge of collapse, tears welling up in his eyes.

"Our sentries outside the city just risked their lives to deliver news that our armory has been emptied!"

Not even a single speck of gunpowder was left!

"All the refined iron and weapons have vanished without a trace!"

"Even the Flying Guillotine Squad has vanished without a trace!"

Lin Zhenxiong stood frozen in place, as if struck by lightning.

After a brief silence.

His smug expression froze.

It turned into an unfathomable, horrifying distortion.

"Snapped!"

The pure gold wine bottle in his hand was crushed and deformed.

Lin Zhenxiong's eyes were bloodshot, and his mental defenses collapsed.

Inside the Taiji Hall, where wine cups were clinking and people were exchanging toasts.

He almost couldn't suppress the desperate roar that was escaping his throat like a pig being slaughtered.
