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

The night was deep, and dark clouds obscured the moon.

Inside Black Wind Stronghold, however, a scene of madness unfolded, with lights blazing and activity raging.

The newly recruited Blood Droplets Second Group, along with the peripheral underlings who had been tricked into joining, all turned into porters.

Since the boss is offering such generous treatment, these ruthless assassins who usually kill without blinking an eye are now working harder than the strongest oxen when it comes to manual labor.

"Quickly! Pack all this refined iron well, make sure it doesn't get damp!"

"Get your hands moving faster! That's gunpowder the boss specifically ordered; if you bump into it, you'll lose next month's pay!"

The assassin leader roared at the top of his lungs, now fully immersed in the role of the chief overseer, giving orders with great enthusiasm.

More than a hundred top assassins transformed into the most powerful and efficient moving team in history.

They displayed superb lightness skills, carrying iron ore weighing over a hundred kilograms as if walking on flat ground.

They even used their profound inner strength to pry off the pure copper edging on the warehouse door frame.

They pluck feathers from the passing geese, leaving not a single blade of grass behind.

Dozens of large horse-drawn carriages were packed full, their wheels leaving deep ruts on the mountain road.

Under the cover of night, the carriage drove into the capital.

We drove into the most remote and desolate corner of the Da Yuan Imperial Palace, the Cold Palace.

This place is deserted year-round, overgrown with weeds taller than a person, and eerily frightening.

Even palace maids and eunuchs would avoid it; it was practically a forbidden zone within the palace.

But tonight, this deathly silent palace is bustling with unprecedented activity.

Su Yaoyao jumped down from the carriage and waved her little hand.

"Tear down that tattered plaque from the Cold Palace! From today onwards, this will be our secret base!"

"Change the name immediately! Da Yuan Royal First Steel Mill!"

The assassins were swift and efficient, and in no time they had flattened the broken threshold of the Cold Palace.

Truckloads of supplies were continuously being transported into the yard.

Following Su Yaoyao's instructions, the refined iron was piled up in the east wing, and the gunpowder was stored in the underground ice cellar; everything was in perfect order.

In the days that followed, the Cold Palace underwent a dramatic change.

Black smoke now rises ceaselessly day and night above the once desolate Cold Palace.

Several enormous blast furnaces were erected overnight, and the charcoal inside burned red-hot under the influence of the assassins' internal energy, reaching frighteningly high temperatures.

Su Yaoyao took off her cumbersome palace attire and put on a neat short outfit.

Holding a charcoal pencil, she filled sheets of rice paper with densely packed blueprints of interstellar weapons.

"The temperature of furnace number two is not high enough! Keep the bellows running! Use your pure Yang internal energy to ignite the fire!"

"The quenching time for these gears must be precise; not even a fraction of a second can be missed!"

Under Su Yaoyao's command, this group of assassins with profound internal strength became the best human precision machine tools.

True qi controls the heat, and internal force is used to forge iron and create parts.

The unparalleled martial arts originally used to kill people were all used as catalysts for the Industrial Revolution.

Inside the palace, the sounds of clanging and booming were constant.

This greatly worried the upright officials in the imperial court.

They submit memorials every day, saying that the Crown Princess is performing rituals in the Cold Palace, causing chaos and disorder, which is contrary to the dignity of the royal family and is improper.

All the folds were slapped back by the tyrant Su Zhen with a big slap.

Anyone who dares to go to the Cold Palace and offend the Crown Princess will be dragged out and given fifty strokes of the cane.

With the emperor's protection, the arsenal in the Cold Palace operated even more recklessly.

Specially made military knives, gleaming with a cold, eerie light, are forged in an assembly line fashion.

The recruited assassins, looking at their new weapons that could cut through iron like mud, were all moved to tears.

But Su Yaoyao's real goal was far more than just these outdated cold weapons.

Time flies.

Only three days remain until the Mid-Autumn Festival banquet.

Inside the Imperial Study.

Su Zhen paced anxiously back and forth in front of the imperial desk, his hands behind his back.

Through the carved window, I watched the black smoke rising from the direction of the Cold Palace.

Just then, a clear, ecstatic voice pierced through the palace walls and crashed into Su Zhen's mind.

Hahaha! Finally done!

In the underground chamber of the Cold Palace, Su Yaoyao looked at the heavy weapons lined up in front of her and was overjoyed.

[Three days until the Mid-Autumn Festival banquet, my heavy-duty production line is finally running smoothly!]

The Gatling gun's six barrels are all made of the finest black iron, with a flawless quenching process!

The gears of the revolver and feeding system mesh perfectly, ensuring there will be no jamming!

[Two hundred homemade high-explosive grenades, mixed with steel balls and broken porcelain shards, have also been sealed!]

Upon hearing this thought, Su Zhen abruptly stopped, his tiger-like eyes widening in shock.

Gatling gun?

Homemade high-explosive grenades?

He had never heard of any of these words before, but just hearing their cold names made him feel an overwhelming aura of dominance and lurking danger.

Su Yaoyao's inner thoughts continued, filled with confidence and extremely arrogant arrogance.

[My damn fear of insufficient firepower is finally cured!]

[General Lin Zhenxiong? Ten truckloads of gunpowder? Thousands of heavy ballistae?]

[On the day of the Mid-Autumn Festival banquet, I, the Crown Princess, will show you, you ancient bumpkin, what true technological superiority looks like!]

What does "3,600 revolutions in a single breath" mean?! It'll turn you into a beehive!

This Crown Princess is going to teach you ancient people what it means for times to change!

In the imperial study, Su Zhen listened with great enthusiasm.

Three thousand six hundred revolutions in a single breath?!

Since the founding of the Great Abyss Kingdom, no one has ever seen such a peerless weapon that sends chills down one's spine just by hearing its name.

He had spent his entire life pursuing absolute force, and hearing such a description of violence made his blood boil!

He knew the general's ambition all too well; the Mid-Autumn Festival banquet was bound to be a life-or-death struggle for the throne.

He was preparing to mobilize 300,000 troops outside the capital to fight Lin Zhenxiong to the death, even if it meant mutual destruction.

It now seems that his precious daughter has exposed the villain's true colors and even created an even more terrifying weapon.

"Okay! Okay! Okay!"

Su Zhen was so excited that he kept rubbing his hands together in the imperial study, his face crinkling with laughter, and he paced back and forth with great excitement.

This is Su Zhen's biological daughter!

No matter what schemes or tricks you have, I'll just use the most ferocious firepower to crush you into mincemeat!

He seemed to already see the miserable sight of the traitors being blasted into dust at the Mid-Autumn Festival banquet.

However, as excited as I am.

The thought of the terrifying destructive power described in his daughter's heart made Su Zhen's heart skip a beat.

If this thing were to actually fire inside the Taiji Hall, it might even blow the roof off the main hall.

If stray bullets fly around or accidentally miss their target, wouldn't he, as the father, sitting on the top dragon throne, become the most conspicuous live target?

No, safety comes first.

Even watching a show or enjoying some gossip requires a safe shelter.

Su Zhen turned around and shouted at the door.

"Guards! Where is the Grand Eunuch? Get in here now!"

The voice was excited and urgent.

The chief eunuch guarding the door was so frightened that he flinched and scrambled inside.

He knelt heavily on the polished gold bricks with a thud.

"Your Majesty, this old servant is here! This old servant is here!"

Su Zhen strode up to the chief eunuch, his eyes burning with anticipation.

"Issue my decree!"

"Immediately go to the Imperial Household Department and have that golden nanmu dragon throne removed from the Taiji Hall!"

The chief eunuch was stunned, his face full of confusion.

The dragon throne in the Taiji Hall is a symbol of imperial power in the Great Yuan Kingdom. Why would they want to remove it for no reason?

"Your Majesty... after we remove it, what... what will we replace it with?"

Su Zhen waved his hand and shouted decisively and without room for argument:

"Change it to solid steel! Make it solid!"

"Craft me a pure steel, explosion-proof dragon throne, and have it quietly moved in tonight!"

"Make the chair back two inches thicker! It'll definitely withstand a massive explosion!"

The chief eunuch broke out in a cold sweat and lay prostrate on the ground, trembling.

Is His Majesty planning to build an iron turtle shell in the Taiji Hall?

Is something terrible about to happen at the Mid-Autumn Festival banquet?

Su Zhen ignored the eunuch's shock.

He put his hands behind his back, turned his head to look out the window towards the Cold Palace, and a cruel, expectant smile curled at the corner of his mouth.

"Go and do it, but don't let the word get out."

The grand show is about to begin!
