Chapter 1: Landing on "Shattered Crystal Beach"-The Obsidian Scouts' Raid

Crystal Core Star's sky was dark purple, with countless translucent crystal fragments floating through it. Sunlight refracted through the fragments into bands of seven-colored light, yet it fell upon the ground with a bone-piercing chill. The landing site, "Shattered Crystal Beach", was made up of countless sharply angled crystal fragments. Pale blue energy liquid flowed through the gaps between them, and stepping on them produced a crisp tinkling, as though the crystals were resonating.

"The energy here is too dense," Xiao Yan said, clenching his fist, his knuckles tingling slightly as his Dou Qi resonated with the crystals. "Even the air is full of tiny energy crystals. Breathing them in makes your Dou Qi sluggish." He circulated his Heavenly Flames, and the flames rising from his palm were refracted by the crystals in the air into countless tiny tongues of fire. "We need to control our Dou Qi output carefully, or we could easily set off an energy explosion."

Lu Mu was adjusting the "crystal energy detector" when more than a dozen red dots suddenly appeared on its screen, approaching at tremendous speed from the northeast. "Something's coming, fast. There are twelve of them. Their energy signatures... they're like concentrated obsidian!"

Before he finished speaking, twelve black shadows shot out of the crystal stone forest at the far end of Shattered Crystal Beach. They were "Obsidian Scouts", less than two meters tall, their bodies covered in smooth black crystal armor and their hands transformed into sharp crystal blades. Their eyes were two clusters of burning orange-red energy, and the fierce wind stirred up by their charge swept crystal fragments across the ground with a piercing scrape.

[System notification: Encountered Obsidian Tribe scouts (level: Mid-Level Dou Wang). Trait: extremely high crystal armor defense. Weakness: energy flows at the joints (orange-red glowing areas).]

"These guys' armor is tougher than Mechanical City's Iron King!" Wu Hao charged first, his Space-Splitting Axe carrying the power of space as it chopped at the nearest scout. With a clang, the axe blade bounced off, leaving only a shallow mark on the scout's armor. The scout swung its crystal blade back at him, and Wu Hao hurriedly blocked with the axe handle. The impact left his arm numb, and a gash appeared in the armor where he had blocked-the obsidian was far sharper than he had imagined.

"Attack the joints!" Xiao Yan's Heavenly Flames transformed into slender threads of fire that wound precisely around a scout's elbow joint, where a ring of orange-red energy was indeed flowing. The moment the threads scorched the energy flow, the scout's movements noticeably slowed, and its crystal blade swung off course. "Zi Yan, burn their knees with Dragon Phoenix Flame!"

Zi Yan spread her wings, and Dragon Phoenix Flame condensed into a dense rain of fire that bombarded the scouts' knee joints. The scouts struck by the flames dropped to their knees one after another, the energy flows at their joints flickering violently as cracks began to appear in their black armor. Lin Xiuya seized the chance to thrust his sword into a crack. Sword light twisted, grinding the scout's energy core to pieces-its body instantly lost its luster and crumbled into a pile of ordinary obsidian rubble.

The battle lasted ten minutes, and all twelve scouts were dismantled. Lu Mu picked up a crystal fragment from one of them, and the detector displayed: "Obsidian energy purity: 70%. Contains 'deflagration factor' unique to the Star Core Mine. Explodes easily at high temperatures." He tossed the fragment to Xiao Yan. "This stuff can be used as a bomb. It might come in handy if we keep it."

[System notification: Obsidian Scouts eliminated. Obtained "Obsidian fragments x36". Unlocked the "Simple Crystal Energy Bomb" crafting recipe.]

Chapter 2: The "Energy Quicksand" Trap in Crystal Energy Canyon

Beyond Shattered Crystal Beach lay a canyon a thousand meters deep. The rock walls on either side were made of transparent crystal, through which blue energy liquid could be seen flowing like frozen waterfalls. A thick layer of golden powder covered the canyon floor. It looked soft, but it was actually "energy quicksand"-anything that sank into it would be broken down into energy particles by the crystal energy within the powder.

"The detector shows a floating crystal bridge in the middle of the canyon," Lu Mu said, pointing toward the opposite side. The bridge was made of pale purple crystal and connected to grooves in the rock walls on either side. "But the bridge is covered in 'crystal energy detection arrays'. Any energy fluctuation above Dou Wang level will trigger an explosion."

Wu Hao picked up a stone and tossed it into the quicksand below. White smoke rose from the stone the moment it touched the powder, and within seconds it turned into golden specks of light. "This quicksand is nastier than the juice of a Heart-Corroding Lotus. Fall in, and there won't even be a scrap of bone left." He looked at the crystal bridge. "What if I try first? Walk across using the least energy possible?"

"No," Xiao Yan said, shaking his head. "The Obsidian Tribe has definitely set an ambush on the other side of the bridge. We need to make a feint in the east and strike in the west." He pointed to the rock wall on the canyon's left side. "The crystal layer is thinner there. The Elemental Core's energy might be able to burn a passage through it."

The group came to the left-hand wall, and Xiao Yan pressed the Elemental Core against the crystal. The core's five-colored light resonated with the energy liquid inside, and an opening wide enough for one person gradually appeared in the wall. "Lu Mu, scan it with the detector. See if there are any traps inside." Lu Mu held the detector into the opening, and a green signal appeared on its screen. "It's a natural crystal cave, leading straight behind the rock wall on the other side of the canyon!"

Once they entered the crystal cave, the crystals in its walls gave off a soft glow, illuminating the winding passage beneath their feet. Faint voices came from the end of the passage, speaking the Obsidian Tribe's language. With the help of the "universal translator", a trophy from Mechanical City, Lu Mu interpreted: "They're saying, 'Guard both ends of the bridge. Once the priest activates the crystal core, this planet will be ours.'"

"Looks like the Origin Crystal Core's activation ritual is nearby," Xiao Yan said, quickening his pace. "We need to find the core before the ritual is complete."

Suddenly, the crystals on both sides of the cave lit up at once, and countless spikes sprang from them, forming a ring-shaped "crystal spike trap"! Zi Yan reacted fastest, sweeping her dragon tail across and breaking the spikes nearest them. "It's triggered by energy detection! Everyone, suppress your Dou Qi!" The group immediately dispersed the energy fluctuations around them, and the spikes indeed stopped growing. But with a clang, the crystal door ahead shut, sealing off their retreat.

[System notification: Triggered Crystal Energy Canyon's hidden trap, "Desperate Cage". Destroy the energy sources in both cave walls (green crystal pillars) to open the passage.]

"There's a green crystal pillar on the left!" Lin Xiuya pointed his sword at the left-hand cave wall. Blue energy flowed around the pillar. "I'll cut it down!" His sword flashed, but the instant it touched the pillar, it bounced back-there was an energy shield on the pillar's surface.

"Use an obsidian fragment!" Remembering Lu Mu's words, Xiao Yan threw a fragment at the pillar. It exploded the moment it touched the shield, briefly cracking it. "Now!" Lin Xiuya thrust his sword through the opening, and the crystal pillar broke with a crack. The spike trap on the left vanished at once.

Wu Hao and Hu Gan joined forces to destroy the crystal pillar on the right. The crystal door ahead slowly rose, revealing the scene on the other side of the canyon-the Obsidian Tribe's main force was gathering in the square across the crystal bridge. Hundreds of warriors surrounded a black altar roughly ten meters tall. Set in a groove at its center was a dark purple crystal the size of a human head: the "Origin Crystal Core".

Chapter 3: The Tribe's Main Force in Obsidian Square

The square was paved with black obsidian, its ground engraved with intricate energy patterns. Orange-red energy liquid flowed through the patterns, connecting them to the Origin Crystal Core on the altar. Hundreds of Obsidian warriors stood in neat formations, shield bearers holding crystal shields in front and archers capable of firing energy projectiles behind them. Three towering warriors stood before the formations, red crystals embedded in their armor. They were clearly leaders.

[System notification: Encountered the Obsidian Tribe's main force (including 3 Dou Emperor-level leaders). The "Origin Crystal Core activation ritual" is underway. Ritual progress: 30%. Disrupting the ritual can weaken the leaders' energy.]

"The one in the helmet in the middle is their leader, Hei Yao," Lu Mu said, his detector locking onto the warrior at the very front. "On his left and right are his lieutenants, Chi Jing and Mo Shi. All three can control crystal energy explosions."

Hei Yao seemed to notice their arrival. The orange-red eyes beneath his helmet turned toward the exit in the rock wall, and he raised his crystal hammer and slammed it into the ground. The energy patterns across the square lit up instantly, and orange-red energy liquid flowed outward along them, forming a ring-shaped energy wall that trapped the group at the edge of the square.

"Outsiders, you dare disturb the great activation ritual?" Hei Yao's voice sounded like two pieces of obsidian grinding together. "Today, you will become nourishment for the crystal core!" He swung his crystal hammer, and dozens of black crystal pillars suddenly rose from the square and hurtled toward the group.

"Scatter and break through!" Xiao Yan tossed the Elemental Core to Lu Mu. "Lu Mu, use the core to disrupt the ritual's energy. Zi Yan, Wu Hao, take care of the archers. Lin Xiuya, Hu Gan, keep the leaders occupied. I'll destroy the altar!"

Zi Yan's Dragon Phoenix Flame transformed into a fire dragon, throwing the archers' formation in the rear into chaos. The flames detonated the energy projectiles the archers fired, setting off a chain of explosions among their ranks. Wu Hao's Space-Splitting Axe cleaved through the crystal shields, opening a gap in the shield bearers' formation. He charged through it, aiming his axe at the warriors' joints, and soon cleared an open space.

Lin Xiuya's sword collided with Chi Jing's crystal blade, sword light and crystal light interweaving in the air. He deliberately infused Dou Qi into his sword, triggering Chi Jing's energy explosion, then used spatial footwork to dodge the instant it erupted, leaving Chi Jing's explosion to injure many of his own people. Hu Gan, meanwhile, used the Black Tortoise Shield to withstand Mo Shi's attacks head-on. The runes on its surface absorbed the crystal energy and sent it rebounding back, blasting Mo Shi's armor full of craters with his own energy.

As Xiao Yan charged toward the altar, Hei Yao's crystal hammer came crashing down with the force to destroy heaven and earth. "Don't even think about touching the crystal core!" Xiao Yan gathered his Heavenly Flames and the Elemental Core's energy into a five-colored barrier before him. The hammer struck it, sending energy ripples across the sky. "Your opponent is me!" Xiao Yan infused his Heavenly Flames into the ground, and the obsidian paving stones suddenly exploded. Lava-like flames spread along the energy patterns, disrupting the ritual's energy flow-the Origin Crystal Core on the altar flickered, and the activation progress stalled at 45%.

"You're courting death!" Hei Yao roared and lunged at him. The red crystals on his hammer burst with dazzling light; he was clearly about to unleash a powerful move. But Xiao Yan suddenly turned and hurled the Elemental Core at the Origin Crystal Core in the center of the altar. The instant the two collided, they produced a powerful energy resonance. The black patterns on the altar began to fade, and the activation ritual was forced to a halt!

[System notification: Origin Crystal Core activation ritual disrupted. Obsidian leaders' energy weakened by 30%.]

Chapter 4: The "Crystal Core Guardian" Atop the Altar

The instant the ritual stopped, the altar began to shake. Four enormous arms made of dark purple crystal emerged from beneath the ground, each gripping a different weapon: a crystal sword, a crystal bow, a crystal spear, and a crystal shield. Golden energy chains coiled around the arms' joints, their ends connected to the Origin Crystal Core at the altar's center.

[System notification: Triggered "Origin Crystal Core Guardian" (level: Peak Dou Emperor). Formed directly from the crystal core's energy; immune to physical attacks. Elemental energy is required to neutralize its crystal energy.]

The guardian had no head, only a purple crystal embedded in its chest that shared the Origin Crystal Core's source. All four enormous arms attacked at once: the crystal sword whistled through the air toward Xiao Yan, the crystal bow fired an energy arrow at Zi Yan, the crystal spear thrust at Lin Xiuya, and the crystal shield guarded the altar, blocking Wu Hao and Hu Gan's attacks.

"Its energy is connected to the Origin Crystal Core," Lu Mu shouted. "We have to sever the energy chains first!" He channeled the Elemental Core's energy into the detector, which fired a green beam and temporarily froze one of the chains. "I can only freeze it for ten seconds! Attack that arm, quickly!"

Xiao Yan seized the chance. His Heavenly Flames merged with the Elemental Core's five-attribute energy, forming a multicolored longsword that struck the frozen chain with pinpoint accuracy. With a crack, the chain snapped, and the enormous arm holding the crystal sword immediately lost its luster and fell onto the altar.

The crystal in the guardian's chest flashed red, and the remaining three arms attacked even more furiously. The energy arrows fired by the crystal bow split into dozens in midair. Zi Yan's Dragon Phoenix Flame burned some of them, but an arrow that slipped through grazed her wing, leaving a purple burn mark. The crystal spear's tip constantly extended and retracted, forcing Lin Xiuya to keep moving and dodging. The crystal shield suddenly expanded, covering the entire altar, and no matter how Wu Hao hacked at it, it did not budge.

"Blow up the shield with obsidian fragments!" Recalling their earlier discovery, Xiao Yan gathered several fragments and ignited them with his Heavenly Flames. The shock wave from the explosion blasted a small hole in the crystal shield! "Now!" Hu Gan gathered all the Dou Qi in his body into the Black Tortoise Shield and smashed it into the hole. The runes on its surface collided with the crystal shield's energy, and the hole instantly widened into a gap large enough for one person.

Lin Xiuya slipped through the gap and pointed his sword at the crystal in the guardian's chest. "Xiao Yan, the energy chain!" Xiao Yan immediately used the Elemental Core to freeze another chain. Lin Xiuya's sword pierced the crystal with pinpoint accuracy, and the guardian's movements froze instantly. Its remaining two enormous arms fell to the ground with a clang and broke into purple crystal fragments.

[System notification: Crystal Core Guardian defeated. Origin Crystal Core energy unstable. Seize and purify it within 10 minutes.]

Chapter 5: Purifying the Origin Crystal Core and Saving the Planet

The Origin Crystal Core at the center of the altar pulsed violently after the guardian's death. Black cracks appeared on its dark purple surface; it could clearly explode at any moment. At the sight, Hei Yao's eyes nearly split with fury, and he charged toward the altar, throwing all caution aside. "I'll see you destroyed along with this planet!"

Wu Hao and Hu Gan joined forces to stop Hei Yao. Dou Qi burst from the Space-Splitting Axe and Black Tortoise Shield at once, holding Hei Yao's crystal hammer in midair. Zi Yan's Dragon Phoenix Flame bound Chi Jing and Mo Shi, while Lin Xiuya wove a net of light with his sword to block the remaining Obsidian warriors. "Xiao Yan, purify the crystal core, quickly!"

Xiao Yan leaped onto the altar and pressed the Elemental Core against the Origin Crystal Core. The core's five-colored light slowly seeped into the crystal core, and the dark purple crystal gradually became clear. But the obsidian energy remaining inside it was exceptionally stubborn, constantly battering the Elemental Core's light. Cold sweat appeared on Xiao Yan's forehead, and his Dou Qi was being consumed at tremendous speed.

"Use the Dew of Life!" Ye Xinlan suddenly shouted. She had been in the rear preparing medicines until now, and she rushed forward with her medicine chest. "Life energy from the Spirit Plant Realm can neutralize any negative energy!" She handed Xiao Yan a bottle of Dew of Life, and he immediately poured it onto the point where the crystal core and the Elemental Core met.

The moment the Dew of Life touched the crystal core, it turned into a green mist of light and merged with the five-colored glow, forming an even more powerful purifying force. The black cracks in the crystal core began to heal, and the dark purple faded completely, leaving it perfectly transparent, with a seven-colored energy flow moving across its surface-the Origin Crystal Core had been successfully purified!

[System notification: Origin Crystal Core purification complete. Crisis of Crystal Core Star's explosion averted. Main quest complete! Team has unlocked the "Crystal Manipulation" talent and obtained an "Origin Crystal Core fragment" (can be used to craft a spatial teleportation device).]

The purified crystal core released gentle energy. Across the square, the Obsidian warriors lost their strength one after another, their armor turning into ordinary stone. Hei Yao stared at the transparent crystal core as the orange-red light in his eyes gradually went out. He fell to his knees before the altar and let out a howl of despair.

Crystal Core Star's sky gradually turned azure. The floating crystal fragments gave off a warm glow, and the energy quicksand of Shattered Crystal Beach turned into fertile golden soil. Under the Origin Crystal Core's influence, the entire planet was reborn.

[System notification: Team status fully restored. "Energy Crystallization" ability activated. Next plane coordinates generated: "Void Beast Nest". Teleportation countdown: 1 hour.]

Xiao Yan held the Origin Crystal Core fragment, which transformed into a transparent ring in his palm. The seven-colored energy flow on the ring echoed the Elemental Core from afar. Looking out at Crystal Core Star as it recovered in the distance, he suddenly understood that whether facing steel, plants, or crystals, true power had never been destruction, but protection and salvation.
