Mark-2? No, Mark-2-Devil!

"My... hair..." Tony ruffled his hair with both hands, making his already messy hair even worse.

"You mean that red-skinned monster we encountered in the cave was summoned by you?" Tony's face was filled with disbelief.

Chen Tian rubbed his nose and chuckled twice.

"Chen Tian... why didn't you summon it earlier? We could've escaped that damned place long ago." Yinsen looked at Chen Tian helplessly as well.

Chen Tian shrugged. "I didn't know I had that ability either. Maybe it was activated right at the moment of life and death."

Tony and Yinsen seemed to accept Chen Tian's explanation. Tony walked over to him and grabbed him.

Tony's eyes gleamed with the light of a mad scientist. "Come on, Dragon Country boy! Let's go to the lab and properly study your 'Summoning Art'!"

He dragged Chen Tian through the living room and down the spiral staircase to the basement amid Pepper's shout of, "Don't blow up the lab again!"

"Welcome to my playground~" Tony snapped his fingers smugly, and the entire underground laboratory instantly lit up like day.

The underground space, as large as two basketball courts, was filled with high-tech equipment gleaming with cold light. Dozens of holographic projections on the circular workbench in the center ran complex calculations. In one corner, several robotic arms automatically assembled armor components, producing pleasant metallic clinks.

"Hahahaha, how's my playground? Quite the eye-opener, right?" Tony sat behind a semicircular desk with Yinsen, tapped a few keys on the virtual keyboard, and said, "Now, let's see your 'magic'..."

He pressed Enter, and the laboratory lights suddenly turned dark red. A circular scanner descended from the ceiling, enveloping Chen Tian from head to toe in blue lasers.

"JARVIS, create a new file, codename... uh..." Tony stroked his chin for two seconds. "Let's call it 'Dragon Country Trick.'"

"Scanning in progress, Sir." JARVIS's voice came from all directions. "File established. Cameras activated. Everything is ready, Sir."

"O... kay! Dragon Country boy! When I give the order, summon that big guy." Tony rubbed his hands excitedly and tapped the desk a few more times, bringing up a 3D projection of the laboratory environment, with various data fluctuating around it.

"Now!" After comparing the data, Tony shouted at Chen Tian. He and Yinsen watched expectantly, waiting for him to summon that "demon."

Instead, Chen Tian stood there awkwardly, the tips of his ears bright red, his expression conflicted.

Tony's eyebrows nearly rose into his hairline. Tilting his head, he stared at Chen Tian like he was looking at a broken robot. "Hello? Dragon Country boy? Did your summon button get stuck?"

Chen Tian's ears were glowing red as he fidgeted with his fingers. "Well... actually..."

"Sir," JARVIS suddenly interjected, "Mr. Chen's heart rate has surged to 132 beats per minute. His adrenaline levels are abnormal."

Tony slapped his forehead. "Oh! I know!"

He strode over to Chen Tian and lowered his voice. "Do you need some kind of... special ritual?"

He waggled his eyebrows and gestured. "Like dancing? Chanting a spell? Or..." He suddenly lowered his voice. "Do you need a sacrifice?"

By the time Tony mentioned dancing and chanting, Chen Tian's entire face had scrunched up.

Tony's eyes instantly shone as if he had discovered a new element, and he clapped his hands. "Ha! I knew it!"

Like a gopher who had found a gold mine, he excitedly circled Chen Tian. "Tell me, Dragon Country boy, what do you need?"

Chen Tian opened his mouth, but before he could speak, Tony interrupted him. "Wait! Let me guess—"

He dramatically stroked his chin. "Moonlight? A crystal ball? Or..."

He suddenly lowered his voice and mysteriously pulled out a black card from his pocket. "Or... this?"

Chen Tian looked at the black card glittering under the laboratory's cold lights, and the corner of his mouth twitched. "Tony, this isn't a money problem..."

"Oh~" Tony drew out the sound, then suddenly snapped his fingers. "JARVIS! Pull up the complete Harry Potter series immediately! Especially the wand-waving scenes!"

More than a dozen holographic screens immediately descended from the ceiling, playing different magic movies at once. Surrounded by wizards waving wands, a vein throbbed on Chen Tian's forehead.

"Sir," JARVIS reminded him at just the right moment, "according to my database, Chinese magic is more inclined toward Incantations than wands."

"Perfect!" Tony spun around and rushed toward the workbench. A robotic arm immediately handed him a roll of parchment and a quill. "Come on, write an Incantation! Make it gold! The glowing kind!"

Chen Tian finally could not take it anymore. "Tony! This isn't..."

"Wait! I know!" Tony suddenly wore an enlightened expression and mysteriously leaned close to Chen Tian's ear. "Do you need... women's clothing?"

He blinked. "I know a few Broadway costume designers..."

"What?!" Chen Tian's voice jumped an entire octave.

My fist had hardened. Where was my knife? Women's clothing? I'd rather jump from here than wear women's clothing!

But Tony was already operating the holographic projection on his own. "JARVIS, search for 'Dragon Country mage cosplay' immediately! The most extravagant kind!"

The projection immediately displayed all kinds of exaggerated traditional Chinese outfits, thoughtfully labeled with phrases like "100% silk" and "hand-embroidered."

Chen Tian looked at the flowing 3D robes and felt his temples throb. Having just acquired swordsmanship, he suddenly really wanted to cut something.

"Tony," Chen Tian took a deep breath, "listen to me..."

"No, no, no!" Tony suddenly thought of something else and excitedly patted Chen Tian on the shoulder. "I get it! It's the venue, right?"

He rapidly worked the virtual keyboard. "JARVIS! Turn the laboratory into... uh... Dragon Country style!"

As the 3D projection transformed the laboratory, several imitation red pillars rose from the floor, lanterns bearing the character "fortune" hung from the ceiling, and a miniature artificial rock garden with flowing water even appeared in the corner.

"How about that?" Tony spread his arms smugly. "Feeling it now?"

Looking at this bizarre fusion of East and West, Chen Tian suddenly missed the peace and quiet of the cave. He rubbed his forehead helplessly. "Tony, it really isn't..."

"Sir," JARVIS suddenly interjected, "based on an analysis of Mr. Chen's facial microexpressions, he may simply be... shy."

The laboratory instantly fell silent. Tony's expression froze as he slowly turned to Chen Tian. "Shy?" The word sounded like an alien language coming from his mouth.

The tips of Chen Tian's ears had already turned purplish red. Tony suddenly burst into laughter, slapping his thigh as he laughed. "Hahaha! A summoner who can summon a hell demon... is actually shy?!"

He threw an arm around Chen Tian's neck and pulled out his phone with the other hand. "Pepper! Come look! Our Xiao Chunan summoner... Agh!" Chen Tian silenced him with an elbow strike.

"Okay, okay." Tony rubbed his stomach and wiped away tears of laughter. "How about this? I'll turn around. I promise not to peek." He turned around dramatically and even covered his eyes with his hands. "JARVIS will shut off all cameras too, right, JARVIS?"

"Actually, Sir, my sensors are spread throughout—"

"JARVIS!" Tony interrupted sternly. "Learn to read the room!"

"All recording devices have been disabled." JARVIS complied smoothly.

Chen Tian looked at Tony's "obedient" back, then at Yinsen beside him, who pretended to study the data while covering his mouth and shaking with suppressed laughter. Finally, he sighed. "Fine."

Chen Tian took a deep breath, wearing an expression as tragic as if he were heading to the execution block. He slowly knelt on one knee, pressed his right fist to his left chest, and tremblingly raised his left hand toward the ceiling.

"In... in the name of chaos and..." His voice was as faint as a mosquito's, and his left hand awkwardly clawed at the air.

Tony's shoulders shook suspiciously, while Yinsen was practically burying his face in the data tablet.

"Louder!" Tony suddenly turned around, somehow holding a loudspeaker. "Put some force into it!"

Chen Tian shot him a vicious glare, closed his eyes, and went all in. "In the name of chaos and fear—Crimson Moon, tear apart reality!"

With the final roar, he fiercely swung down his raised left hand. The entire laboratory suddenly shook violently, and every instrument blared a piercing alarm. The ceiling lights flickered, and the air filled with the smell of sulfur.

The temperature in the laboratory surged abruptly, and dark red magma-like patterns seeped eerily across the steel walls. Several of Tony's beloved limited-edition sports cars suddenly caught fire, orange-red flames licking their bodies with heartbreaking crackles.

"My 1967 Shelby GT500!" Tony let out a heart-wrenching scream.

The flames slithered over the floor like living creatures before finally gathering into a blazing vortex five meters wide in the center of the laboratory.

A terrifying figure three meters tall slowly rose from the vortex's center—dark red scales covered its entire body, curved horns rose like a crown, and pupils burning with hellfire looked down upon everyone.

"My lord," Diablo's voice sounded like the wails of countless souls. "Lord of Purgatory, nightmare of angels, terror of mankind, King of Fear—Diablo answers your summons."

Chen Tian peeked through his fingers with one eye. Seeing Diablo's exaggerated entrance pose, he wanted nothing more than to dig a hole and crawl into it on the spot. Gritting his teeth, he lowered his voice. "Could you... put away all that fire?"

Diablo nodded. "Oh, oh, no problem."

With a wave of its hand, the flames that had been raging through the laboratory vanished instantly, as though they had never existed.

But Tony was already as excited as a child with a new toy. He circled Diablo, occasionally tapping the demon's scales with a wrench. "Incredible!! This material! These energy fluctuations!"

He suddenly stopped and looked at Chen Tian with shining eyes. "Dragon Country boy, can we make a deal—can I borrow your pet for a few days?"

"Pet?!" Diablo's flames instantly surged three meters high, and the laboratory temperature soared. "Ant! How dare you—"

"Tony!" Chen Tian hurriedly interrupted. "He's not a pet!"

He turned to Diablo and made a calming gesture. "Calm down. This is... uh... my sponsor. You know, I need to... um, spend money in the real world too."

Diablo eyed Tony suspiciously. "This noisy mortal?"

"Yes, yes, the noisy mortal." Chen Tian wiped the sweat from his forehead. "But he's rich. He can provide... sacrifices!" He frantically winked at Tony.

Tony immediately caught on and snapped his fingers. "JARVIS! Prepare the highest-grade... uh... demon feed?"

"Sir, I recommend preparing living sacrifices," JARVIS answered seriously. "According to The Key of Solomon, higher demons prefer..."

"Stop!" Chen Tian quickly cut him off. "No sacrifices!"

He turned to Diablo and forced himself to say, "Well... can you cooperate with an experiment? Just... stand still?"

Diablo's flames gradually calmed. "Since it is my lord's request..." It arrogantly raised its head. "Five minutes. Not one second more."

Tony was already impatiently directing robotic arms to bring over all kinds of instruments. "JARVIS! Start the holographic scan! Record all energy data!"

Rubbing his hands, he looked at Diablo's scales. "This material is perfect... if I can replicate it on armor..."

Seeing Tony's fanatical expression, Chen Tian suddenly had a bad feeling. "Tony... don't tell me you want to..."

"Mark-2-Devil!" Tony excitedly expanded a holographic projection. A dark-red armor model with demon horns rotated in the air. "Hellfire Ejectors! A magma shield! It can even spray sulfur breath to interfere with enemy radar!"

Diablo suddenly leaned closer, its eyes flowing with firelight fixed on the projection. "Mortal, you have some creativity after all."

It extended a claw and tapped the projection. "Add a tail spike here. Arrange the scales in reverse here..."

"Genius!" Tony excitedly high-fived the demon, then shook his hand wildly after getting burned. "You understand design!"

Chen Tian and Yinsen looked at each other. Yinsen whispered, "Should I prepare some holy water or something..."

Under Diablo's "professional guidance," the design blueprints for the Mark-2 armor from the movie plot became unrecognizable at a visible rate.

The originally sleek gold-and-red armor was now completely transformed into a dark-red, savage demon style—

Head: The originally smooth faceplate had been changed into a vicious demon face, with curved horns extending from both sides. Two clusters of hellfire burned in the eye sockets, flickering whenever Tony spoke.

Chest: Dark-red runes now surrounded the original circular reactor position, occasionally spraying sparks that smelled of sulfur.

Shoulders: The originally simple shoulder armor had become sharp, scale-like plating. Every piece resembled a demon scale, with edges sharp enough to cut the air.

Arms: The original palm cannons had been changed into "Hellfire Ejectors." Diablo insisted on installing small bone spikes on the wrists, claiming that "you can stab people with them in close combat."

Legs: The original thrusters had been changed into "Abyssal Flame Propulsion." The soles could even spray sulfurous smoke, giving Tony a demon-descending special effect whenever he landed.

Back: The most outrageous part was that Diablo insisted on adding a pair of retractable "Demon Wings" to the armor's back. Although Tony protested that "this thing doesn't conform to aerodynamics at all," Diablo merely snorted disdainfully. "Mortal, what do you know? As long as it looks cool, that's enough."

Chen Tian looked at the holographic Mark-2, which no longer resembled the original design at all, and the corner of his mouth twitched. "Tony, are you sure this can still be called Iron Man armor?"

Tony stroked his chin, his eyes gleaming. "Of course! Mark-2 Devil Edition! It looks way cooler than my original design!"

Diablo folded its arms proudly. "Mortal, you finally have some demon taste."

Yinsen silently wiped away cold sweat. "I think... if the military sees this, they might launch a nuclear missile immediately."

But Tony was already eager to begin assembly. "JARVIS! Start manufacturing immediately! I want to wear it before tonight!"

Diablo stood with its arms folded, watching the excited Tony with an unfathomable expression before nodding in satisfaction. "Mm, very good. You have spirit. Since you are a mortal as insignificant as an ant, but considering you are my lord's companion..."

Grimacing in pain, Diablo tore one of its own scales from its arm and tossed it to Tony.

After catching it, Tony was burned by the scale's heat and began tossing it up and down.

"This scale is for you. You can use it to forge your 'toy.'" As it spoke, it looked at Chen Tian. Seeing his speechless expression, it gave him a twisted "friendly" smile.

"My lord, I shall leave first. I look forward to your next summons." After leaving those words behind, countless streams of magma surged beneath Diablo's feet, swallowed it, and vanished from the laboratory.

"Woohoo! My armor can be upgraded again!" Tony tossed the scorching scale onto the workbench. "Come on! Let's witness the birth of a great work!"

Chen Tian looked at the plot, which had completely gone off the rails, and sighed. "...Fine. At least it's better than women's clothing."
