Sky Curtain: The opening scene explains the four major cases of the Ming Dynasty plus the early Ming

"A heartless cannon?"

This strange name surprised everyone in the myriad worlds and timelines.

What kind of cannon is this?

Why does that sound so inappropriate?

The Ming Dynasty, Hongwu Hall.

Zhu Yuanzhang also looked puzzled. He turned to the Minister of War and asked:

"Have you ever heard of this kind of cannon?"

The Minister of War knelt down, his forehead covered in sweat:

"Your Majesty, I...I am ignorant and have never heard of such a thing."

Zhu Yuanzhang waved his hand, signaling him to get up, and then looked back at the sky with anticipation.

This fourth son's 18th-generation descendant always manages to come up with some novel and frightening gadgets.

Above the sky, Zhu Dijun's face revealed a smile that sent chills down the spines of all the Qing emperors.

"Family members, don't let the name fool you, its power is beyond your wildest imagination."

"Actually, the official name of the 'Heartless Cannon' is the 'Flying Thunder Cannon,' which is a crystallization of wisdom invented by our Chinese descendants in a war to establish our nation in modern times."

Its principle is extremely simple!

The chibi-style characters reappear on the screen.

This time, instead of going to the blacksmith's shop, they came to an open space.

A small figure was seen carrying an empty large gasoline drum.

"See that? That's the cannon barrel!" Judy Jun pointed at the gasoline drum, making a startling statement.

"Cannon...cannon barrel?"

Everyone was dumbfounded.

Using a tin bucket as a cannon barrel?

If this thing fires, it'll probably blow its own people into the air first.

"I know what you're thinking," Judy Jun said with a smile. "Don't rush, just keep watching."

In the picture, a chibi-style figure holds a gasoline can at a 45-degree angle, half-burying it in the ground, with only the mouth of the can showing.

"Because our gun barrels are not strong enough, we have to rely on the power of the earth to withstand the impact of the gunpowder explosion."

"By partially burying it in the ground and compacting it with soil and stones, it becomes a sturdy gun mount!"

This simple yet ingenious solution caught the eye of all the craftsmen!

"I see! Using this land as a foundation—brilliant! Absolutely brilliant!"

"Then, the shells."

Zhu Dijun's voice became even more excited.

"The 'Heartless Cannon' is called 'Heartless' because its shells are absolutely inhuman!"

"We can stuff bundles of explosives inside!"

"We can stuff the cast iron ball inside!"

"We could even stuff a bundle of sharpened steel bars, a huge pile of rubble, and nails inside!"

"Anything that can explode, smash, or kill the enemy can be stuffed in!"

"Its range isn't far, only about a hundred or two meters. But what it fires is despair! It's overwhelming destruction!"

Judy Jun's voice is incredibly captivating.

"Imagine dozens of 'heartless cannons' firing simultaneously when the enemy charges!"

"The sky was filled with explosives, a rain of iron, and stones!"

"One shell hits, creating a huge crater; within a radius of several meters, men and horses are thrown about, and flesh and blood are flying everywhere!"

"This isn't war, it's cleaning up trash!"

"Tell me, isn't this thing 'heartless' or not?"

"hiss--"

Across countless worlds and timelines, gasps of astonishment filled the air.

Too bad!

That's incredibly toxic!

This isn't a cannon! This is clearly smashing a small mountain directly into the enemy's head!

In the Tang Dynasty, Li Shimin looked at the terrifying animated demonstration on the screen, his face turning pale.

His prized Xuanjia Army, if faced with such an unreasonable weapon...

He dared not think any further.

"This thing... is against the natural order."

Changsun Wuji, standing beside him, managed to utter a few words with difficulty.

Li Shimin shook his head, a fierce glint in his eyes: "No, Fuji, you're wrong. You must use a hunting rifle to deal with wolves!"

"To deal with those 'wild boars in human skin' who don't treat themselves or others like human beings, this kind of 'heartless' method is the way to go!"

His words expressed the sentiments of all Han emperors.

To be merciful to the enemy is to be cruel to oneself!

"Of course, I know that gasoline drums didn't exist in ancient times."

Zhu Dijun then changed the subject.

"But you can use wood to make a sturdy iron barrel, or use clay to make a huge earthenware pot, and then bury it in the ground in the same way."

"The power might be a bit weaker, but it's more than enough to deal with those Manchu soldiers wearing cloth and cotton armor!"

"The 'heartless cannon' is a deadly weapon in positional warfare. But if you want to fight in urban warfare, to capture cities and strongholds, you need a more flexible weapon."

As Zhu Dijun spoke, he took out a dark, pottery-like object from behind him, with a fuse attached to it.

"I call it a 'makeshift grenade'!"

"Or, you can call it 'Palm Thunder'!"

"This thing is even simpler to make than a musket!"

Zhu Dijun projected a chibi-style animation onto the sky.

"The first step is to find a sturdy earthenware pot, gourd, or even a bamboo tube. The size should be large enough to hold in one hand."

"The second step is to tightly pack in the purified black powder particles we just mentioned."

"The third and most crucial step is to insert the 'shrapnel'!"

"Stuff the entire clay pot with all the nails, scraps of iron, shards of porcelain, and pebbles you can find, along with gunpowder!"

"Finally, insert a fuse soaked in gunpowder to ensure a stable burn, and then seal the opening with wax or mud!"

"A simple and efficient 'palm grenade' is now ready!"

Judy weighed the model in her hand and a mischievous smile appeared on her face.

"How do you use this thing? It's very simple."

"Light the fuse, count to three, and then throw it into the enemy ranks with all your might!"

In the picture, a chibi-style character throws a smoking pottery jar into the middle of another group of chibi-style characters dressed as Qing soldiers.

"boom!"

A loud bang.

The earthenware jar shattered!

Countless black dots, like a torrential rain, splashed outwards in all directions!

Those chibi-style Qing soldiers were instantly riddled with holes, their bodies riddled with all sorts of "shards," their health bars emptied in an instant, and they vanished as pixel blocks.

"Family members, did you see that?"

"In the instant of the explosion, everything inside this small ceramic jar would be turned into deadly shrapnel!"

"Its kill radius can reach five to ten meters!"

"One shot is enough to wipe out a small group of enemies!"

"In narrow streets, on siege ladders, this thing is the Grim Reaper's scythe!"

"Imagine you throwing hundreds or thousands of 'palm bombs' down from the city walls as the 'wild boars' charge at you, howling and screaming!"

"What a magnificent sight that must have been!"

"How delightful the sound of that explosion must have been!"

Judy Jun's voice was full of endless inflammatory rhetoric.

In all times and spaces, those Han soldiers and civilians who were once driven to the brink of despair by the Qing army's butcher's knife now have flames of revenge burning in their eyes!

Nanming, Jiangyin.

Having held out in the besieged city for dozens of days and on the verge of running out of ammunition and food, the registrar Yan Yingyuan looked at the sky and tears streamed down his face.

He seemed to see countless "palm-sized grenades" raining down from the sky, blasting the vicious Qing soldiers outside the city into a bloody mess!

"Heaven has not forsaken our Han people! Heaven has not forsaken our Jiangyin!"

He kowtowed three times heavily to the sky.

"Pass down the order! Collect all the pottery, tiles, and ironware in the city!"

"Use all gunpowder at once!"

"We will let those Tartars outside the city taste the power of this 'palm-sized thunderbolt'!"

The entire city of Jiangyin, on the verge of destruction, burst forth with unprecedented vitality!

The Qing Dynasty era was already a desolate wasteland.

Emperor Kangxi, Emperor Qianlong, and all the princes and ministers were pale and looked as if they had lost their parents.

Muskets... heartless cannons... homemade grenades...

When these simple, cheap, yet incredibly powerful killing weapons were revealed to the public in such detail by that damned young man.

They knew that their military advantage, on which they depended for survival, had vanished.

From this day forward, the Aisin Gioro family will no longer face peasants wielding swords and spears.

Rather, it was a nation armed to the teeth, filled with hatred, so large that it drove them to despair!

"The vast ocean of people's war..."

Emperor Qianlong absentmindedly recited a sentence that had just floated across the sky, and felt a chill run from the soles of his feet straight to the top of his head.

He and his empire are about to be completely swallowed up by this sea!

Above the sky, Zhu Dijun finished playing all the "teaching courses".

He stood up, his gaze seemingly piercing through time and space, looking at his ancestors who were struggling in the darkness and fighting in despair.

"I have given you both the weapons of thought and the weapons of war."

"You'll have to walk the rest of the road yourselves."

"Remember, a single spark can start a prairie fire!"

"Go fight! Go seek revenge!"

"Go and sweep those usurping robbers, along with their traitorous lackeys, into the dustbin of history!"

"With your blood and courage, let us rebuild the glory of our Chinese nation!"

"The grandeur of the Han and Tang dynasties!"
