One man's resistance against Japan, I mobilized a million people to aid Shanghai.

Beppu Bay, Wajima Island, "Industrial No. 1" Joint Processing Center.

This area was originally a desolate salt flat and abandoned small port along the coast.

Now, however, it has been completely transformed, becoming the largest and most efficient "purification engine" in Sha Wujin's "Three-Day Blood Edict" plan.

He named this small port "Industry No. 1", meaning "Industrial purification, the No. 1 project".

Stretching for dozens of miles, barbed wire fences have enclosed the mudflats into several huge "camps awaiting treatment."

Japanese pirates, driven from the western part of the island, were transported here by train, truck, and even on foot like a tide.

They no longer distinguished between "prisoners of war" and "civilians," referring to them collectively as "raw materials."

At the entrance, "sorters" dressed in gray protective suits and gas masks, armed with stun guns and stamps, are conducting assembly-line operations.

Regardless of age or gender, all clothing, shoes, and socks were forcibly removed and thrown into a nearby incinerator.

Under the guise of "epidemic prevention and disinfection," the real purpose was to eliminate individual characteristics and the possibility of concealment, and to recycle fabric fibers for the manufacture of low-grade military supplies.

The naked crowd was brutally driven through a disinfection pool by high-pressure water guns, washing away most of the dirt on their bodies and further weakening their will to resist.

After the body is half-dry, fluorescent numbers are quickly burned onto the forearms for easy identification at night.

They were divided into groups of one thousand people and escorted into different "pre-processing cages" by soldiers armed with rifles.

These cages, constructed from large logs and barbed wire, are open at the top and have muddy floors at the bottom, offering no shelter and are extremely crowded.

Because the Japanese pirates had no clothes to cover themselves and were confused by the whole process, they had no will to resist.

Unbeknownst to them, not far from the pretreatment cage were dozens of giant pits that had been dug out.

This is the core of Sha Wujin's invention, embodying his ingenious design that combines chemistry with large-scale purification.

These giant pits are located on the mudflats, each over 100 meters in diameter and about 15 meters deep.

The pit walls and bottom were covered with a special mixed layer several meters thick. The bottom layer was impermeable clay, above which were interspersed flammable coal and quicklime, and the top layer was covered with porous slag.

Each pit has several tall slides that lead directly to the bottom.

During the process, the selected "raw material groups" are driven to the top of the sled, which is steep and slippery. People fall into the pit in droves as they are pushed and shoved and under the gun barrels.

When a certain number of animals gather at the bottom of the pit, usually between 10,000 and 20,000, Sha Wujin on the command tower will press a button to inject a large amount of seawater.

The Han River water gushing out from the pre-installed pipes in the pit wall reacted violently with the quicklime.

In an instant, the giant pit turned into a boiling hell.

The reaction releases scorching steam that permeates the air. The quicklime expands and disintegrates upon contact with water, mixing with the slag and coal at the bottom of the pit to form a scalding, viscous slurry.

The animals that fell in first had their respiratory tracts burned by the high-temperature steam, and then struggled in the viscous, scorching liquid.

The screams were drowned out by the boiling "glug" sound.

The heat of a chemical reaction is sufficient to rapidly decompose and carbonize organic matter.

The entire process takes less than five minutes, and a pit of "raw materials" is turned into charred, smoking paste-like residue and bone fragments.

Subsequently, the discharge gate at the bottom of the pit was opened, and the residue was discharged into the sea. After simple cleaning, the pit can be put into use for the next round.

These large pits were later called the Boiling Pit.

......

Chang Yuchun's instructions were simple and direct.

"Aim for maximum daily purification volume, slaughter every village and city you encounter, take no prisoners, delay, kill them all, burn them all!"

Southern Annam, delta plain.

A village with a population of several thousand.

early morning.

The old clan chief is leading the clan's younger members in broadsword training.

"Children, remember this: you are Annamese for all your lives."

"The alien races have occupied our land, and we are no match for them now, but we will surely be able to reclaim our glory in the future."

The old clan chief looked indignant.

In his youth, he served as a soldier in Thang Long province and harbored strong racial sentiments.

In his view, what right did the Tu ethnic group have to occupy the cities of his Annamese people?

He wasn't the only one; many villages in the south thought the same way.

They, the Annamese, will never yield.

The clan members were all filled with righteous indignation, desperately swinging their broadswords and hacking at the straw man in front of them.

It was as if those damned alien races were right in front of him.

Just as they were sweating profusely, a clap of thunder suddenly rang out—

"Boom!"

"Boom!"

A cavalry regiment under Chang's command surged in like a dark cloud, quickly surrounding all the exits.

The old clan chief was startled and quickly told his clansmen to put away their broadswords. He forced a smile and was about to step forward to feign politeness.

This time, however, the person who came was expressionless and didn't bother to say a word.

They didn't try to persuade or warn them; they just started attacking.

First, the artillery launched a rapid barrage of fire on the settlement, collapsing the pagoda and setting the bamboo houses on fire.

Then, the cavalry roared in and hacked down the fleeing villagers with their sabers.

The infantry followed closely behind, searching house to house, dragging out those who were hiding, and executing them on the spot.

The able-bodied men were gathered in the rice paddies outside the village and machine-gunned.

Some people sought refuge in Buddhist temples, only to be engulfed in flames.

The corps commander, riding his horse, surveyed the village strewn with corpses, and roared at his staff officer:

"Count! Count them now! Report the numbers immediately! If you delay General Chang's progress, I'll skin you alive!"

The soldiers roughly searched the bodies and made a rough count.

Subsequently, the entire dam area was set on fire, with thick smoke obscuring the sky.

Without hesitation, the corps rushed towards its next target.

Their goal is to "net 10,000 people per day".

Besides here, there's also the Mekong River region.

This is a densely populated area, and most people in the Indochina Peninsula live along the river.

For larger towns along the river, more "efficient" tactics were often employed.

First, they surrounded the city with a large force, then sent messengers into the city to issue an ultimatum, giving all residents one hour to assemble at a designated location outside the city for reorganization.

Some desperate towns chose to comply. As the dark mass of people nervously gathered on the riverbank, heavy machine guns and mortars, which had been lying in ambush on the hills on both sides and on the boats on the river, suddenly opened fire!

Crossfire swept the crowd down in swathes, like harvesting wheat.

The earth was dyed red, and the river was blocked.
