The film opens with several voices speaking in rapid succession:

"The hides of Indians can be made into fine tall boots!"

"America must exterminate the Indians!"

"Kill one Indian every ten minutes!"

"The only good Indian is a dead one!"

The opening scene is drenched in blood. First, a close-up of white teeth between parted lips. Then an iron pair of pliers clamps down on a tooth and wrenches it free from the gum. Blood gushes from the socket. The camera pulls back to reveal a Black man bound tightly to a wooden stake shaped like a crucifix. The one extracting his teeth is a werewolf, who examines each tooth carefully, rinses it, and places it on a tray already laden with many others. The agonized screams of the Black captives mingle with eerie music to create a hellish soundscape—oppressive enough to make one's blood run cold.

The camera pulls further back. At the center of a grim plantation estate, dozens more Black people are bound to stakes. Each is displayed in the posture of Christ on the cross, arms spread wide, palms pierced through by iron nails. Blood streams from their hands and bodies. They writhe and scream in agony. The entire scene is an earthly purgatory.

Werewolves methodically extract teeth from the captives' mouths with iron pliers—keeping some, discarding others. The carefully selected teeth fill a tray and are carried into the manor's great hall. Inside, the servants are a more varied lot: werewolves, vampires, ghouls, liches. Bound to the hall's pillars are young women, metal tubes plunged deep into their chests. When the wooden stoppers are pulled from the tubes, dark crimson blood flows from the openings into ornate glass bottles. Servants carry the filled bottles with utmost deference and present them to two masters seated at the head of the hall.

Both masters wear Western suits, but their faces are those of a werewolf and a ghoul. The werewolf is, naturally, Washington. The ghoul is Jefferson. The two pour the maidens' blood from the glass bottles into silver goblets still stained with residual crimson, chatting and drinking as they go.

After a while, an enormous bat swoops into the room, circles once, and plunges toward the floor. A plume of white mist rises from the point of impact, and from within it emerges a figure—Lincoln, of course.

"Why hasn't Theodore arrived yet?" Lincoln drains a cup of blood in one gulp, then asks.

"He's busy. Can't make it for now," replies Washington the Werewolf in a muffled voice. Then he opens his mouth to reveal rows of fangs. On every tooth, intricate black runes are inscribed in impossibly fine lines. Washington suddenly shakes his head violently, and the fur on his face writhes like kneaded dough. Through a dizzying sequence of transformations, his head finally stops shaking—and the werewolf's visage has transformed into that of an ordinary man. Washington opens his mouth again. There is not a single tooth inside. He selects the teeth that suit him from the tray and installs them, one by one, into his own mouth—teeth extracted from the mouths of Black men.

Lincoln the Vampire pays no attention to Washington's antics. Turning to Jefferson, he says: "We must use the Philosopher's Stone to resurrect the Cherry Tree. To forge the Philosopher's Stone, we need more lives. Exterminating every last Indian won't be enough. We need more blood for the sacrifice."

Jefferson the Ghoul's face is shrouded in dark miasma. In a chilling voice, he replies: "What do you need me to do?"

"We must establish a new nation and let them be fruitful and multiply. Then, through a single massive alchemical blood sacrifice, we refine over a hundred million Americans into the Philosopher's Stone." Lincoln speaks at an unhurried pace.

"Oh..." Jefferson stares at Lincoln and answers.

Lincoln removes his tall top hat and sets it on the table. Luminous alchemical patterns bloom across the black hat, and then a map of the Americas materializes above it in its entirety. Lines crisscross the map, forming a complex alchemical array that covers the entire continent. "This is Theodore's research."

Washington and Jefferson lean in to examine the array. Lincoln points to it and says: "Those key nodes must be inscribed with Blood Seals, etched by the resentful blood of the dead in vast quantities. There must be brutal wars in these places—brutal massacres. Jefferson, I need you to write a constitution. Deliberately leave loopholes in it. Let the American South begin keeping slaves, and after a few decades—a century, even—we'll exploit those loopholes to start a war. By then there will be enough blood to water this land."

Jefferson smiles with arrogance. The sinister dark aura makes his face look absolutely hideous, yet carries an overwhelming air of superiority. "I'll take care of it in Philadelphia," he answers.

The screen then unfolds against the backdrop of this continental alchemical array. To inscribe each Blood Seal on this vast map, the monsters lead America through the Revolutionary War, the "purchase" of Louisiana, the Civil War, and Westward Expansion. All of it follows the plan laid out by the three monsters already introduced and the fourth—the "Alchemist" Theodore—shown only as a sinister silhouette. Wherever a finger points, a massacre follows. Indians are herded into the alchemical array and refined into blood-red stones. These crimson stones are then transported to the very center of the array, where a stone sarcophagus stands, its surface carved with the exquisite pattern of a tree in bloom.

Running through the American alchemical array is the great railroad. "Beneath every railroad tie, a wronged soul must be buried!" The Alchemist Theodore's sinister voice echoes across the continent. The four great American figures and the descendants and protégés of the monsters under their command drive America to enforce its blood-soaked policies with ruthless efficiency. The scene shifts: the camera descends from the American railroad tracks to what lies beneath—row upon row of neatly arranged corpses of Indians and Black people. The railroad that forms the alchemical array stretches on and on, and for every mile of track, there are bones and wronged souls to match.

"We need more blood!" In the background, Washington, Jefferson, Lincoln, and Theodore howl in unison.

Chinese audiences had never seen a film like this. The grand scale—a continent-spanning conspiracy with an entire nation as its backdrop—gave viewers the feeling of watching a historical epic. Of course, most of the audience had received at least a middle-school or high-school education, and many could connect what they saw to the historical events recorded in their textbooks. Setting aside the fantasy elements, the historical events depicted were all real. So by the time the Chinese laborers arrived in America by ship to make a living, the audience had already built up enormous anticipation—and dread.

Chinese laborers in America were primarily engaged in building the railroads. Among them was a Maoshan Taoist priest who went by the Daoist name "the Adept." Upon arriving in America, the Adept immediately sensed that something was wrong—he could feel the ground beneath his feet crawling, as though countless human beings were writhing below. The sensation made his skin prickle with unease.

The boss of the railroad construction crew the Adept joined was a low-level vampire descendant who, in addition to drinking blood, had a taste for human flesh. Quite a few Chinese laborers had been devoured by this creature. The Adept finally uncovered the truth and, drawing upon Maoshan sorcery, destroyed the vampire. The news alarmed the werewolves, vampires, and ghouls who controlled America. They immediately moved to hunt down and kill the Chinese.

Faced with such a perilous situation, the Adept chose not to flee. The railroad built by the Chinese laborers had already completed the continental alchemical array. If it was not destroyed within seven days, every human being on the continent would be refined into the Philosopher's Stone.

"Even if I'm the only Chinese person left in America, I will destroy this alchemical array," the Adept told his companions. Some chose to leave, abandoning America. Others bravely stayed to fight alongside him. With the help of an American woman who had discovered the truth, and a ragtag band of desperate American Black men and white drifters, a tiny band of heroes fought their way toward the evil heart of the nation.

Along the way, they slew every ghost and demon that crossed their path. Black comrades, white American misfits, even Chinese companions fell one by one. At one point they formed a temporary alliance with the Church, which was vying for control of America's power. But the Church, which they had counted on as an ally, had long ago betrayed its God and defected to the forces of evil. The Archbishop first performed a divine summoning ritual—but at the very moment God was about to descend, he sealed God away with black dog blood and unclean runic swords.

The Archbishop, who had until then carried a faint air of sanctity, revealed his dark and evil true nature. Gloating over the contaminated God upon the altar, he declared: "These runes are the ones inscribed on Washington's teeth. Even Satan's curse is not so wicked."

The injured Adept, ambushed and captured by the Church, raged: "Why are you doing this?!"

"Because what we truly enjoy is toying with the bodies of men! Why else would we worship God? Why else become priests?!" The Archbishop's face twisted with obscene rapture. "What we clergy particularly savor is the flesh of little boys! Those bodies, those pure souls, those cries and that terror—it's exquisite!"

At this critical moment, the American woman transformed! Leopard-like claws erupted from her hands and feet. She dispatched the priests holding the Adept, and together they killed the Archbishop and his followers, freeing the imprisoned God.

God's face was a mask of shame. He mumbled, "Didn't see that coming! Didn't see that coming!..." and vanished from the altar, leaving the Adept and the gravely wounded American woman behind.

On her deathbed, the American woman finally revealed her origins. She carried the bloodline of Washington the Werewolf. During one of his massacres of the Indians, Washington had violated a holy maiden of an Indian tribe. The holy maiden, who possessed the knowledge of nature's laws, transformed into a leopard-woman and escaped. Thus, a branch of the werewolf bloodline was passed down in this fashion. Her descendants wanted revenge but could find no way—until, after meeting the Adept, the American woman finally found someone she could rely on and stepped forward to fight.

In her final moments, the American woman pressed the Indian tribe's sacred artifact—the "Eye of Truth"—into the Adept's arms and carefully straightened his collar. With her dying breath, she whispered in his ear: "Find Cherry & Green..."

"I'll save you!" the Adept cried, tears streaming down his face as he prepared to cast a spell.

The American woman pressed down on his hand. "Save your strength for vengeance... Adept, I love you..." And then she was gone.

The Adept, now alone, set the church ablaze. Against the backdrop of towering flames and the American woman lying peacefully at rest within, his resolute face and rage-filled eyes moved countless women in the audience to tears.

At the evil heart of America—the core of the continental alchemical array—the Adept, aided by the Eye of Truth, saw through the illusion. What appeared to be a land of picturesque mountains and clear waters was in reality an inferno concealed by sorcery. Countless broken human forms writhed in hellfire, emitting wretched, agonized cries.

Over the thunderous pounding of a giant heartbeat, through this world of darkness, a hellish anthem reverberated:

*Scream, oh scream, and moan, oh moan—O the endless darkness of Hell! Sprites and demons and wicked ghosts, cradling severed heads, await your arrival. Fall, fall, O humanity, plunge down now...*

*Fall, fall—O the endless darkness of Hell! Burned by fire, drowned by water. Unable to live. Unable to die. O humanity—fall at last...*

*Fall to the deepest reaches of Hell. Listen! The fallen ones begin their chant—in pools of blood, in seas of fire, on mountains of needles...*

At the very instant it seemed the darkness would devour him, the Eye of Truth blazed with brilliant light, illuminating a treacherous narrow path. Wading through blood and pulped flesh, the Adept broke through the outer reaches of America's evil heart. He scaled a mountain built from human corpses and molten rock, pulled open a small door at the summit, and burst into the very center.

At the center of the evil heart lay a world that resembled paradise. Washington the Werewolf, Jefferson the Ghoul, Lincoln the Vampire—and the fourth, who had until now been shown only as a sinister silhouette—the Lich, the "Alchemist" Theodore Roosevelt, was there with them.

"You think you can stop us?" The evil monsters—who had perpetually faked their deaths only to reappear in new guises—finally revealed their true forms. "You never realized we were beside you the entire time?"

They gleefully displayed their various transformations one by one. The Adept realized that he had encountered each of these creatures throughout his journey, and some of their disguises had even infiltrated his demon-slaying party, only to "die heroically" along the way.

Seeing the Adept's stunned expression, the monsters roared with laughter. "Soon this world will belong to us! We shall obtain eternal life and power! We only let you come this far so that someone could witness our triumph with their own eyes! Once we succeed, your blood will serve as the fine wine for our victory celebration!"

The monsters' overwhelming power was indeed beyond what the Adept alone could withstand. To the strains of "Sephiroth"—a Latin choral piece in the grand European style, plagiarized by Chen Ke—the Adept engaged all four monsters in battle. Fighting one-on-one, or even one against two, he could hold his own. But one against four was too much. The Adept was beaten to the ground.

In his moment of crisis, the Adept used the Eye of Truth once more. Visions of the past unfolded before him. It turned out that "Cherry & Green" was the English translation of a name belonging to a powerful Norse witch. She had been lured to America by Washington's father under false pretenses, invited as a guest through trickery.

Washington's father had attempted to seduce the powerful witch. Once she was carrying his child, he planned to refine the witch, the child, and his own evil soul together into a Trinity—an immortal being of boundless power, the supreme demon.

Washington discovered his father's scheme and attempted to seduce the witch himself. Father and son fought viciously over the woman, and Washington lost. After his defeat, Washington, driven by the mentality of "if I can't have her, no one will," ambushed the witch and struck off her head with the very axe she used to chop firewood.

Washington's enraged father, upon seeing the witch's corpse, summoned the entire Washington werewolf clan. First, he made a show of furious questioning: "Who cut down Cherry & Green?!" His intent was clearly to kill Washington.

But when Washington stepped forward boldly, axe in hand, and admitted he had done it, his father's rage transformed into a smile. He praised Washington for his honesty and courage, and even bestowed upon him several precious gifts.

Washington secretly followed his father and overheard him speaking to his mother about the matter. Washington's mother wondered why her husband had let the boy live.

Washington's father explained: the axe possessed tremendous power—the power to slay demons and monsters. Seeing Washington standing there with the axe, clearly ready to fight to the death, it was only natural to swallow one's pride and retreat.

Armed with this invaluable intelligence, Washington ambushed his father at the first opportunity, and with the divine power of the axe, became the leader of the werewolf clan. He then allied himself with Jefferson, Lincoln, Theodore Roosevelt, and other beings of power. Their plan: forge the Philosopher's Stone through the continental alchemical array, use it to resurrect the Norse witch, carry out his father's Trinity ritual, and achieve undying immortality.

Now that he had seen through his enemies' weakness, the Adept drew the axe from the ground before the sarcophagus of "Cherry & Green" at the center of the continental array—and slew all four monsters. Amid howls of "We'll be back!" the evil heart of America transformed into a colossal mountain, upon which the carved likenesses of four figures appeared.

The film does not reveal the Adept's fate. Instead, it cuts directly to another scene: the United States Congress debating and passing the Chinese Exclusion Act. Enraged congressmen cast their votes. Their faces flicker ceaselessly between those of various monsters and ordinary humans, and the hands protruding from their shirt cuffs shift back and forth between human hands and bestial claws.

On this supremely dark note, the film draws to a close.
