Breaking an Immortal
Appearing out of thin air in front of a sprawling, white and blue castle that resembled a palace from the Han Dynasty, Cai Sicong sighed as he dusted off his blue hanfu and walked towards the giant structure that served as his primary residence. Entering through the massive front gate, several servants bowed and greeted their master as he continued deeper into the palace to reach his immense bed chambers.
"Lord Cai is back!" a woman in a gorgeous red and pink hanfu announced as she spotted the cultivator, where she immediately threw herself on him in a tight embrace.
"Lord Cai, I missed you!" another, taller woman in a purple and white hanfu cooed as she nuzzled his hair while her large chest absorbed the back of the man's neck between them.
"Lord Cai, I missed you so-" still another woman who was in a green and yellow hanfu began, before recoiling at the sight of her master. "Y-you're mouth, Lord, there's blood!!"
"Oh dear, I apologize for appearing before you ladies in such a condition," Cai Sicong replied as he wiped the bloody corner of his mouth on his sleeve. "I was dealing with something and my body must still be healing. It's okay, I'll be fully restored in a moment."
"Someone hurt you?!" the taller woman stammered in awe. "B-but Lord, you're an immortal! You've long since been immune to damage!"
"Well worry not, my love, I've dealt with the threat," Sicong answered as he slumped down on a large cushion as he intended to relax with his harem for the rest of the afternoon.
Before anyone could say another word, the entire castle trembled as what sounded like distant thunder sent light shockwaves over the frame of the massive structure. His eyes becoming awash in blue light again, the cultivator growled as levitated off of his cushion as he sensed an immense power heading that way.
"L-Lord Cai, there's been a huge disaster at the Rose Capitol!" a servant stammered as she appeared in the doorway. "T-the city, all the buildings. They've been reduced to splinters!"
"Don't tell me," Cai Sicong hissed as he raised his arms. "Get me behind me, girls, because-
Suddenly, the entire castle and its many occupants seemed to melt away while the structure buckled and burst as if it was hit by a giant invisible wall. The cultivator was helpless to watch as his palace evaporated into a swirling explosion of stone, wood, and furniture while the place was reduced to rubble in less than a second.
"HAHA found you!" a naked Saitama exclaimed with his fist raised and pointed at where the palace once stood.
Now under the blue sky outside, Cai Sicong turned around to see that his luxurious residence had been reduced to rubble. Although he himself was far too powerful to be effected by the attack, no one else from the castle had survived.
"If you wanted to incur my wrath, then congratulations," the cultivator stated as his face contorted into an expression of ire as he raised an arm. "I don't know how you escaped that dimension, but I'll be promptly taking us back to another one so that we can-"
Faster than an instant, Saitama had blitzed past Cai Sicong and reappeared at the other side of the ruined castle. Turning to his side as he was surprised by his opponent's increase in speed, the cultivator's eyes widened as he realized that one of his arms had been severed.
"Sorry to disaPOINT you, but we'll be having the fight here!" the bald villain laughed as he used the torn limb to point at the blue-clad man.
"Then I'll tear you apart quickly," Cai Sicong muttered as he used a spell to cauterize his wound. His remaining hand then briefly trembled while it became awash in a brilliant gold light. "I'm going to imbue my palm with the gravity of a neutron star. Whatever I touch with it will be repelled with the same force."
"Then don't just talk about it, be about it!" Saitama teased. He got his wish a second later as the cultivator teleported right in front of him.
"Quasar Force Palm!" Cai Sicong yelled as his hand slapped against the villain's face.
Despite the fact that he was holding back the insurmountable energy that he'd gathered in his palm, the cultivator still managed to accidently destroy the entire continent that he was standing on as trillions of tons of material was ejected from the planet and thousands of square miles were utterly demolished.
"Oh dear, I've made quite a mess," Cai Sicong admitted to himself as he detected the souls of millions of people leaving their obliterated bodies. "Not to worry, I'll direct my energy to restoring the planet to the way it was, I still have 10 gold pills in my inventory. The important thing is that the very disturbing man is out of the picture, I don't even sense his life force in this solar system anymore."
Indeed, the force of the immortal cultivator's attack had propelled Saitama away from the alternate Earth at nearly twice the speed of light. Smashing through several asteroids, the bald villain opened his mouth in awe as the range of colors that he could see increased due to the immense speeds that he was traveling.
"HAHA what a light show!" Saitama remarked as he unclenched his thighs, where he pulled out the mother box from between them, having stored them safely tucked against his nude body for the fight. "That pretty boy sure is something else! I'm itching to tear him to shreds now!"
Activating the cube, the caped baldy was sucked into a boom tube, where he reappeared back on Earth with his velocity reduced to nothing. Standing within a giant crater that once housed the greatest empire of the ancient parallel world, Saitama was impressed that his foe's attack had done so much damage to the planet.
"So you survived that, huh?" Cai Sicong asked as he appeared in the air above the crater. "I figured that my attack only had a 10% chance of killing you, but at least it wasn't fruitless. I see you're injured."
"Huh? Injured?" the bald villain asked, before gingerly touching his nose to find he had a hand-shaped bruise in the middle of his face. "Ohhh…Ohhh!!! HAHAHAH yes, you've manage to pop a few of my blood vessels! An injury indeed, albeit, a tiny superficial one!"
The cultivator master watched in awe as Saitama began to strain himself as if he was trying to push something out of him. His bald face turning red, the one punch man's light bruising began to fade away within a few seconds.
"Did you just heal yourself?" Cai Sicong asked. "I didn't detect any energy emitting from you, how did you do that?"
"I just commanded my capillaries to repair themselves and sure enough, no more bruise!" Saitama smirked as he crossed his arms. "Not bad at all though, pretty boy, that's definitely more injured than I've been in years!"
"…well, I see that simply killing you through physical injury will be impossible," the immortal admitted as he closed his eyes. "But every river has more than one bend. I can simply use a different solution to rid this universe of you."
"Well, I'm all ears, buddy boy! HAHAH!"
Raising his one arm above his head, Cai Sicong's hand began to glow green as many animal spirits started to appear in the skies above him.
"This is a taboo form of magic, but I don't have a choice," the cultivator explained. "Do you have a favorite animal, child?"
"Rhinoceros beetles are awesome!" Saitama replied as he clasped his hands together. "They have that big horn to smash things hehe they remind me of me!"
"Very well, then you'll live out the rest of your life as one!" Sicong yelled as he aimed his hand at his opponent. "Forbidden Arts: Supreme Transmogrification Cannon!!"
A giant beam of swamp-green energy blasted towards Saitama, the spectacular attack carrying with it the ability to transform its targets into a different animal.
"Serious Series: Sebum Reflector!" the bald clown exclaimed through a broad smirk. Clenching his body, Saitama super-charged the sebum glands in his head, where his bald scalp promptly became oily and shiny.
"Farewell, child, I will always remember you as the opponent who almost bested me," Cai Sicong smiled, only to open eyes to see his own attack flying back at him.
A radiant explosion of green light briefly filled the sky, before it dissipated and left Saitama standing alone in the crater. At least, he was nearly alone…
"You're so cool looking now! HAHA that attack was awesome!" the caped baldy laughed as he rushed over to pick up the rhinoceros beetle that had dropped from the sky.
"Did you…did you reflect my attack?" the beetle replied in Cai Sicong's voice as he came to the horrific realization at what had happened.
"Yep, I made my forehead all shiny and reflective and lookie there, it worked on your beam!" Saitama continued in his mocking laughter.
The large beetle's exoskeleton fell silent, as the spirit of the immortal cultivator endured a quiet mental breakdown at the realization that he had just suffered an extraordinarily humiliating defeat.
