Sky Curtain: An Initial Overview of the Immortal Lord of the Myriad Laws of the Mortal World

[The scene shifts, the battle is intense. Without a word, Hai Gong unleashes a shower of paper figures of the Abbot Jin Xian. They are paper, yet also the sharpest weapons. At the Arctic Circle, amidst the swirling snow, a battle erupts for the "hand drum"—the crucial clue, "small mountain."]

Faced with the overwhelming onslaught from the Nine Realms Gate, Hai Gong employed a variety of tactics. "Immortal Cloud Flying Stones" burst forth from the paper, transforming into the crushing weight of real meteorites; "A Moment of Change" allowed the paper figures to shift unpredictably between reality and illusion. Even though the Nine Realms Gate reacted swiftly, instantly forming an encirclement to block them, the tacit understanding ingrained in Hai Gong and Hai Shan erupted at this moment. A golden cicada shedding its shell! Using the visual obscuring effect of the flying paper figures, the two, like slippery eels, gained a brief advantage in the skirmish.

The world of Jujutsu Kaisen.

On the evening before the Shibuya Incident, Gojo Satoru sat on a bench in front of a vending machine, his long legs casually crossed. Beneath his black eye mask, "Six Eyes" was rapidly analyzing the information on the screen. The Kikufuku bag he was carrying swayed slightly, and a cynical smile played on his lips.

"Ha... this uncle named Hai Gong is really adorably reckless. The incantation circuit of that 'Abbot Golden Immortal Paper Doll'... oh no, I mean spiritual circuit, is incredibly precise. He gives two-dimensional paper three-dimensional mass, and even creates a momentary spatial displacement effect at that instant called 'Golden Cicada Shedding Its Shell.' This isn't something that can be done with just brute force."

He tilted his head slightly, as if talking to thin air, or perhaps to himself: "Compared to that high-ranking official with piles of rotten oranges, this old man's combat IQ is top-notch. He's surrounded, yet he acts like he's strolling through his own backyard. That 'Momentary Change' move, wasn't it a provocation? Absolutely a provocation. If Hui were here, I'd show him the true use of 'Shikigami.' Compared to those barking 'tamagu,' these paper figures that can be used as substitutes or bombs at any time are much more in line with the aesthetics of modern sorcerers. But—those old guys from the Nine Realms Gate look just as annoying as the old men here. I really want to crumple them up and throw them in the trash."

The world of Assassin Seven.

At the entrance of Da Bao's hair salon on Chicken Island, Wu Liuqi held a pair of beef offal scissors that hadn't been sold yet, shaking his leg while staring at a projection on someone's wall.

"Ah Zhen fell in love with Ah Qiang... no, it's this big guy who fell in love with gang fights." Wu Liuqi, speaking with a thick Cantonese accent, twirled the scissors on his fingers. "Oh my, I love this 'Golden Cicada Shedding Its Shell' technique! For an assassin, the most important thing isn't how to kill, but how to escape! Look at that movement, tsk tsk tsk, handsome! So many skills coming at you, just like I dodged that Plum Blossom Thirteen's darts, whoosh and you're gone. Hai Gong... Hai Gong... that name sounds like he's really tough. But those bad guys in black are so unethical, so many of them bullying two people, can't they even use some 'fancy moves'? If I had my Demon Blade Thousand Blades, hmph, I could cut down ten thousand of those paper doll tactics! Chicken Da Bao, do you think we should learn a few moves? So that next time someone... someone comes after us, we can just turn into paper and fly away, saving on ferry tickets!"

[In the middle of the battle, the situation took a sharp turn for the worse. The Nine Realms Gate was clearly enraged, and dozens of powerful cultivators no longer held back, their devastating attacks shearing away layer after layer of ice from the Arctic. Hai Gong and Hai Mianmian, the island lord of Yingzhou who loved wearing crop tops, stood side by side, fighting the enemy relentlessly, disregarding their own lives.]

Even as his arm was severed by a chilling divine power, blood spurting onto the pristine white paper figure, Hai Gong didn't even flinch. The paper fragments fluttered, instantly coalescing at the severed arm, reforming, and he threw a punch! Retreat? That word didn't exist in his dictionary.

The world of One Piece.

Oni Island, on the edge of a battlefield ravaged by war. Roronoa Zoro, his jaws clenched on Wado Ichimonji, his other two swords already drawn. Gazing at the scene in the sky where Kaiju's severed arm refused to retreat and his paper arm grew back, a sharp glint of admiration flashed in the single eye of this three-sword style swordsman.

"That was a heavy slash... but that man's bones are even harder," Zoro said in a deep voice, his voice piercing through the cacophony of battle cries. "You think losing an arm will stop him? Don't be ridiculous. For a true Asura, as long as they can move, they'll bite off a piece of their enemy's flesh, even with their teeth, even with all these pieces of paper flying around! That guy called Hai Gong, his eyes have changed... those aren't eyes of pain, they're eyes of resolve. Like my vow to become the world's greatest swordsman, what this guy carries is far heavier than his arm! Hey, if this kind of tough guy were on this ocean, I'd definitely buy him a drink! But now... since you won't back down, I have no reason to lose to these Gifters! Three Thousand Worlds—!!!"

The world of "A Thought Through Eternity".

In the Lingxi Sect, Bai Xiaochun was hiding inside a giant tortoise shell, peeking out half his head to look at the sky. His face was pale with fright, and he was clutching a handful of pills tightly in his hand.

"My god! This is terrifying! His arm is broken! How much pain must it have caused!" Bai Xiaochun trembled as he wrapped the tortoise shell even tighter. "Senior Hai Gong... why did you do this? Immortality is the only true path! If you can't win, just run! Your paper doll escape technique is so powerful, you could have just thrown a couple of talismans to blow them up, right? Why did you have to stubbornly endure it? Look, look, blood is spurting out! No, no, even my arm hurts just looking at it... but..."

Although Bai Xiaochun was afraid of death, the fear in his eyes was gradually replaced by a sense of awe. He swallowed hard: "But if I don't fight with my life, if I don't protect the people I want to protect, then what's the point of cultivating immortality? Senior Hai Gong... he could have run away, but he has someone behind him, so he can't. This feeling is just like when I was protecting the Luo Chen family... Sigh, never mind! Senior Hai Gong is a true man! Although I, Bai Xiaochun, am afraid of death, if I ever encounter this situation, I will... I will use pills to blast them all away! I will never back down!"

However, despair ultimately arrived. The Great Talent of Immortality—Hai Shan's strongest reliance—was lost. Without the Great Talent's support, Penglai was utterly at a disadvantage. Hai Shan was trapped inside that terrifying parasite by Baili Yuan, the sect leader of the Nine Realms Gate, unable to move.

[A frenzied encirclement, a relentless siege. Hai Gong and his men were like a small boat adrift in a raging storm, on the verge of capsizing. But under this extreme pressure, Hai Gong unleashed unprecedented potential. Using the "Paper Boat Finger Technique," he tore a hole in their predicament, achieving an incredible counterattack!]

The world of "Fox Spirit Matchmaker".

Beneath the Bitter Love Tree in Tushan, Bai Yuechu stood with a colorful stick dangling from his mouth and a handful of snacks he had just snatched. He appeared nonchalant, but his eyes were actually gleaming.

"That was incredible! Faster than my speed at grabbing discounted bento boxes!" Bai Yuechu mumbled, chewing on a lollipop. "That wasn't just any paper boat; it was fueled by his life. That Baili Yuan is a real scumbag, using such disgusting tactics as parasites. Hai Gong's 'Paper Boat Finger Technique'... to be honest, it's neither scientific nor mystical; it's pure willpower burning money! He's betting his magic, soul, and potential like his last banknote! Look at his movements; even though he's at his limit, he can still weave through the gaps in that parasite... tsk tsk tsk, how much does he want to win? But, pushing himself to this point for friends and beliefs, this kind of losing proposition... does it seem familiar to me? Ugh, it's infuriating; it makes me want to get all fired up too."

The true tragedy unfolded in the next instant. To utterly destroy Hai Shan, Baili Yuan unleashed a fatal blow.

Without any hesitation, truly without any hesitation. In the instant Hai Shan was severely injured and unable to move, Hai Gong, his massive body like a mountain, stepped forward without regard for anything else.

[“Pfft—!” The Soul-Slaying Hand. It was a poisonous hand capable of instantly annihilating the soul, piercing Hai Gong's chest without any resistance. Blood splattered, staining the ancient glacier beneath their feet crimson.]

Demon Slayer world (Mugen Train arc node).

On top of the speeding Mugen Train, Flame Pillar Kyojuro Rengoku's fiery hair danced wildly in the wind, his once cheerful smile frozen into utter solemnity. He stared at the image of a chest pierced through, as if foreseeing his own impending fate.

"Hmm! Is this the duty of a 'Pillar'...? Although you're not a member of the Demon Slayer Corps, this spirit truly makes you a pillar supporting the world!" Kyojuro Rengoku shouted, his voice booming yet trembling slightly. "Well done, Lord Kai! Even with your body pierced, even with your heart stopped beating, your burning spirit shines brighter than the sun! Never let malice harm the seedlings behind you, never let hope be extinguished before your eyes! Even if we face an Upper Moon named Hyakuri Abyss... no, even if we face a monster like Muzan Kibutsuji, we absolutely cannot back down! Your chest may be pierced, but your soul—nothing can harm your soul! Burning brightly in this icy wasteland, you are a true warrior! Let your heart burn!!!"

Life was slipping away rapidly, but Hai Gong's hand, his only remaining hand, even somewhat broken, gripped tightly, like an iron clamp, the arm Bai Liyuan had plunged into his chest.

He was laughing. In his dying moments, to give Hai Shan that one in ten thousand chance, he used his own crumbling soul as chains to bind this arrogant villain.

"Do it!" In the instant their eyes met, Hai Shan understood the resolute determination in that exchange.

[The Peach Blossom Immortal Technique is activated! Taking advantage of this fleeting moment of vulnerability, the flower blooms in an instant, stealing the guest's life! Baili Yuan's identity as a "magical corpse," hidden beneath layers of disguise, is finally revealed in this attack!]

The world of Naruto.

On the rooftop of the Hokage's office building in Konoha Village, Nara Shikamaru dropped a shogi piece, the "Kagema," from his hand with a thud. His usual "What a nuisance!" vanished without a trace, replaced by a profound respect for the masterful tactics and tragic sacrifice.

"He's going to die... He's using his own life to set up a trap, to exchange for that one and only chance to become general." Shikamaru's eyes were somewhat dazed. "In that instant, that old man named Kaigong must have calculated everything that would follow. He knew he wouldn't survive, and he also knew that if he didn't restrain Baili Yuan, everyone would die. So, he chose to make himself the 'bait,' the pebble that jammed the gears. The moment the Soul-Slaying Hand pierced his body was when the trap truly activated... It was incredibly reckless, but it was definitely the optimal solution. Although my reason tells me it's a tactical victory, looking at that scene... Ah, this is troublesome, it feels like I have sand in my eyes. If it were Asuma-sensei, he would definitely have done the same, right? The so-called 'jewel' is something that must be protected to the very end."

[Bai Liyuan has revealed himself, but at a heavy price. Hai Gong's primordial spirit was completely annihilated by that attack. Even the so-called genius of immortality, capable of seizing life force, could not repair this paper body that had already turned into nothingness.]

Hai Gong fell, but he looked neither at the enemy nor at his horrific wounds.

In his final moments, with trembling hands, he tossed out a prepared suicide note. It was a letter he had written before his departure, still warm from his body. That profound love, along with the letter, burned in the polar winds, turning into sparks that spread across the entire sky.

There were no grand pronouncements, only the rough man's most tender words of advice: "Please pass a message to my wife and apprentice... Don't be sad, becoming a ghost is a dead end, we—are on the right path."

The world of Fullmetal Alchemist: Brotherhood.

In the warm living room of the Hughes family home, Mas Hughes, who had been showing off his daughter Alicia's photo, froze under the warm light. The photo slipped from his fingers, and as he looked at the sky, tears streamed down his face, a face that usually wore the silly smile of a father.

"That bastard...that big idiot!" Hughes's voice choked, barely able to speak. He rubbed his glasses hard, but couldn't get them dry. "What 'walking the right path,' what 'no need to grieve'...do you know what you're saying? Do you know how much pain those left behind will suffer? Someone as loving as you, a tough guy who cries at the mention of family, how much pain must have been in your heart when you wrote this suicide note! You still wanted to go back and cook for your wife, you still wanted to watch your apprentice grow up...what kind of promise are you making! But...but I understand. It's because there are so many people you love behind you, it's because you have to protect their future, that's why you have to stand there, isn't it? Hai Gong...you're a bastard, but you were also the best father, the best husband. I can't accept this kind of death, but I...I respect you as a real man!"

The world of Fairy Tail.

In the guild hall, Natsu Dragneel was surrounded by raging flames. The usually boisterous, hot-blooded idiot was now clenching his fists, head bowed, his expression unreadable. Happy stood silently to the side.

"I heard it too..." Natsu suddenly raised his head, his eyes burning with a mixture of anger and respect. "'Walking on the right path'! That's a man's farewell! Even if he turns to ashes, even if his soul is gone, that old man's voice still reached his comrades! This isn't a 'dead end,' it's a 'path to survival' for the guild, for the family! Although I don't understand cause and effect, or any kind of karma, anyone who dares to risk their life for their comrades is our family! Hey, you bastard named Baili Yuan, if I ever run into you, I'll beat you to a pulp! I'll give back Uncle Hai Gong's arm, his tears, his letter, everything! Fire Dragon's Roar!!!"

The world of Gintama.

Inside the Yorozuya, Sakata Gintoki was idly picking his nose, his JUMP magazine untouched for a long time. Sadaharu was fast asleep beside him, while Shinpachi and Kagura were shouting at the sky. Gintoki remained silent for a long time, then picked up the strawberry milk on the table and took a sip. His eyes remained dead fish-like, but for a fleeting moment, a blood-red glint seemed to flash in them, reminiscent of the Joui War.

"Hey, hey old man, you left way too cool." Gintoki crushed the empty milk carton and tossed it into the trash can. "'Being a demon is a dead end,' huh... Hmph, what a cool line. In this shitty world, most people live and then become demons, selling their souls for profit, for survival. Someone like you, who regrets it to the core (not really), but refuses to bow down and become a demon, is now an endangered species. Your wife and apprentices, if your stupidity reaches them, they'll cry themselves to sleep. Even if life gets really tough later, remembering your last stupid line will probably make them curse and wipe away their tears as they keep going. That's what 'human' is, fragile as a sheet of paper, but that soul called 'Bushido'... no, 'Koudou' (the Way of the Sea) is harder than any other profession. Goodbye, you crybaby tough guy."
