Ok. Here is the version I adjusted according to the style you requested. I tried my best to make the language more individual, using some colloquial expressions and adding more vivid and prominent emotional changes, while maintaining the original plot and information density
"Optimized version:
As soon as the four of them stepped into the spirit world, they felt as if they had fallen into a flowing starry river. Beneath my feet was a medium of spiritual energy like liquid crystal. With every step I took, a circle of ripples would spread out. My figure was reflected back and forth in those fragmented light patterns, looking so beautiful no matter how I looked at it. The "starry sky" above is no ordinary firmament. It is a sea of light formed by the convergence of spiritual energy sources. The light spots shuttle like a group of fireflies. When they touch the skin, they bring a slight warmth, like the gentle breeze of a summer night, soft and reassuring.
But don't let this beauty blind you. That suffocating sense of oppression swept over in an instant
The Dark Lord was floating right in the middle of the sea of light, and the dark energy around him spread like ink, polluting the pure spiritual energy all around. Those once bright, starry dots were instantly swallowed up, leaving only black, distorted marks, like torn strips of cloth, so ugly that it made one want to vomit.
"After a thousand years, finally someone dares to step into my territory." "
The voice of the Dark Lord was so terrifying that it made one's scalp tingle. Unlike the voice of an ordinary human, it sounded more like thousands of voices superimposed on each other. Sometimes it was as majestic as a deity, and sometimes as hoarse as a monster. He slowly turned around, and his true form was fully revealed
That figure was so tall that it made one look up, reaching a height of ten meters. It was covered in tattered silver armor, with the golden emblem of "Radiant Guardian" still remaining on it, but it had long been eroded beyond recognition by the dark energy. The lower body was not human legs but tens of thousands of tentacles, wriggling wildly in the ocean of spiritual energy, with each tentacle entwined with fallen spiritual runes. The most terrifying thing was that face
Half of it was the handsome face of a silver-haired deity, while the other half was covered with spider-web-like black cracks, from which dark purple-black energy flowed. In those golden eyes, there was no warmth at all, only a terrifying greed.
You were once the guardian of the spirit world. Why did you betray your mission?
Lin Yuan tightly held the protective tooth in his hand. The illusory image of the Wolf God became increasingly solid in the air of the spirit world. The silver-white Wolf fur shone with light, resonating with the surrounding spiritual energy. Upon hearing the words "Guardian", the face of the Dark Lord's deity suddenly distorted violently, half of its face twisted as if it had gone mad, and then it let out a shrill laugh: "Mission?" The mission you mentioned? Back then, the elders of the spirit world, in order to preserve their positions, regarded me as a sacrifice to seal the darkness! It was the dark energy that saved me! Now, I will use my spiritual energy origin to reshape this hypocritical world!"
As soon as the words were spoken, the tentacles of the Dark Lord swung forward like a storm. In an instant, dozens of black energy blades shot out from the ends of the tentacles, crashing down on the four of them like a torrential rain.
"Disperse and act according to the plan!"
Lin Yuan made a sudden leap, and his Wolf claws emitted a golden-blue light blade, precisely shattering the energy blade coming towards him. The violent shock wave pushed him back several steps, and the psychic medium began to ripple violently. Sylvia was quick-witted and swift, blowing the tidal snail. The distant sound of the snail echoed through the spirit world. The blue ocean spirit energy surged out, forming a water shield that blocked the energy attack from the side. The ripples on the water shield flowed like fish scales, layer by layer counteracting the dark energy.
Green Feather quickly pressed down the vitality leaf. The pale green light spread out on the leaf, and in an instant, a giant Venus flytrap grew. The leaf edge glowed with silver light and firmly bit the two energy blades that had escaped. The small barbs on the surface of that leaf absorbed dark energy and actually bloomed a small purple flower.
"Elena, lock onto the light pattern on his chest!" That's the only place where he hasn't been completely eroded!"
Green Feather's words were almost out of breath. The giant Venus flytrap had already begun to gradually turn yellow under the erosion of dark energy.
Elena's robotic arm precisely locked onto the target. The silver core was dazzlingly bright. The psychic cannon switched to "penetration mode", and the muzzle condensed into a slender silver-white arrow, with fine mechanical patterns entwined around the arrow body. "Psychic armor-piercing arrow, fired!"
The light arrow shot towards the golden coat of arms on the Dark Lord's chest like a shooting star. The Dark Lord sneered and waved his tentacles to block it, but the light arrow suddenly split into dozens of tiny arrowheads, evading the tentacles' obstruction and almost all hitting the golden coat of arms.
"Sizzle!" "
The golden coat of arms was instantly struck by a light arrow, shining brightly. The Dark Lord let out a painful roar, and the cracks on half of the deity's face became even more terrifying.
"You guys have successfully angered me!" "
The Dark Lord suddenly raised his head, and the dark energy around him instantly skyrocketed. The light sea in the spirit world violently shook, and all the originally shining light spots went out. The Spirit world fell into a deathly silent black realm. The body of the Dark Lord swelled, his tentacles became even thicker, and the fallen runes wriggling on his body like living creatures, exuding a terrifying aura.
"He is absorbing the dark energy of the spirit world!" If this continues, the spiritual energy origin will be completely contaminated!"
Sylvia's face turned deathly pale, and the blue light of the tidal snail began to dim. The summoning speed of the ocean spirit energy gradually couldn't keep up with its consumption.
Lin Yuan's heart sank sharply. Suddenly, he recalled the intelligence sent by the Tidal Star - the core of the spiritual energy origin was hidden deep in the brilliant sea of light behind the Dark Lord.
"We must approach the spiritual energy origin in order to activate the complete sealing array!" " He gritted his teeth and said.
"I'll create opportunities!" "
Elena suddenly injected all the energy of the robotic arm into the precise core. A silvery light burst out, instantly forming a huge mechanical barrier, converting the surrounding spiritual energy into defensive energy.
"Go around behind him!" I can hold on for at most ten seconds!"
The mechanical barrier had just taken shape when the tentacles of the Dark Lord came crashing down with great force. The silver barrier shook violently, and the crack was almost about to shatter in an instant. Elena's mouth was dripping with blood, and the outer shell of the robotic arm had begun to crack.
"Hold on!" "
Lin Yuan let out a loud roar, completely fusing the power of the Wolf God with the energy of the Tidal Star. The illusory figure of the Wolf God behind him spread its wings, carrying him like an arrow leaving the bowstring, charging towards the Dark Lord. He swung his Wolf's claw, and the long sword interwoven with gold and blue drew a brilliant light trail in the air. The runes on the blade flickered as he fiercely slashed towards the tentacles of the Dark Lord.
"Wolf God Breaks the Evil Slash!" "
The long sword slashed down, golden light burst forth, several tentacles snapped with a thud, and black corrosive liquid spilled onto the psychic medium, making a terrifying "sizzling" sound.
Taking advantage of this opportunity, Sylvia and Green Feather suddenly rounded around from both sides. Sylvia tightly bound the tentacles of the Dark Lord with her psychic chains, while Green Feather controlled the vines to grow rapidly and tightly bound the tentacles.
"Right now!"
Lin Yuan leapt up suddenly. The power of the Wolf God and the light sea of the spiritual energy origin resonated violently. The light spots in the light sea rushed towards him like a tide, condenching a huge light gate in front of him. The illusory figure of the sealing array gradually emerged
