Lin Yue and Su Qingyan Cooperate to Slay the Guardian Beast

The roars of the Chaos Thunder Leopard gradually faded. Just as Lin Yue and Su Qingyan breathed a sigh of relief, they heard heavy footsteps approaching from ahead, causing the ground to tremble slightly. The two exchanged a look and instantly became alert—clearly, there were other guardian beasts in the secret realm.

"It's a Mysterious Iron Lizard!" Su Qingyan's expression changed slightly. She had seen records of this fierce beast in the Chaos Creature Compendium. "Its entire body is covered in Black Iron Scales, it controls the Metal Law, its defense is extremely strong, and it can even manipulate surrounding metal to attack enemies!"

Before she finished speaking, a lizard about three zhang long, entirely black, emerged from the end of the passage. Its scales were like polished black iron, emitting a cold luster. Its limbs were thick as pillars, and each step it took caused fine cracks to appear on the ground. It was indeed the Mysterious Iron Lizard.

Upon seeing the two, a ferocious glint flashed in the Mysterious Iron Lizard's scarlet eyes. It let out a low growl from its throat, and the scattered black iron fragments around them suddenly floated up, shooting towards the pair like arrows.

"Quick, dodge!" Lin Yue shouted, pulling Su Qingyan to the sides. The black iron fragments grazed their clothes and struck the rocks behind them, sending sparks flying.

"This won't work if it continues like this, its metal attacks are too relentless!" Su Qingyan said urgently, her fingertips erupting with flame. She condensed a wall of fire several zhang high to block them. Most of the black iron fragments melted upon hitting the fire wall, but a few still pierced through and continued their assault.

Lin Yue stared at the Mysterious Iron Lizard, his mind racing. He noticed that while the lizard's scales were tough, the scales at its joints were relatively weaker. Furthermore, each time it manipulated metal for an attack, there was a brief pause in the fluctuations of the Metal Law at its joints—that was its weakness!

"Su Qingyan, use your flames to form a fire wall to block its charge, and then use fire sparks to disrupt its vision!" Lin Yue said quickly. "I'll attack its joints; that's where the Metal Law is weakest!"

Su Qingyan immediately understood. Her flames surged again, making the fire wall thicker. Simultaneously, countless tiny fire sparks flew out from the fire wall, circling the Mysterious Iron Lizard like fireflies, obscuring its vision.

Disturbed by the fire sparks, the Mysterious Iron Lizard roared and charged fiercely at the fire wall, attempting to break through the defense with its body. It moved with incredible speed, carrying immense force. It was just about to collide with the fire wall.

"Now!" A sharp glint flashed in Lin Yue's eyes. The Chaos Energy in his dantian whirled wildly, and he simultaneously activated the Law of Stability from a Dao Rhyme Fragment, merging the two energies to condense an even more refined "Enhanced Chaos Light Orb." This orb shimmered with a faint golden light on its surface, exuding a stable and domineering aura.

He aimed at the joints of the Mysterious Iron Lizard's forelimbs and hurled the orb. The orb whistled through the air, accurately striking the joint.

"Bang!"

With a muffled thud, the Law of Stability instantly froze the metal energy at the joint. The Mysterious Iron Lizard's forelimb suddenly went limp, its massive body lost its balance, and it crashed heavily to the ground, kicking up a cloud of dust.

"Good opportunity!" Su Qingyan seized the moment, condensing a searing flame spear at her fingertips. The spear was crimson all over, radiating an aura of utter incineration. She aimed at the Mysterious Iron Lizard's eye—the only vital spot not covered by Black Iron Scales—and hurled it with all her might.

The flame spear shot out like a meteor towards the lizard's eye, and with a "swish," it accurately pierced into it.

"Roar—!" The Mysterious Iron Lizard let out a heart-wrenching scream. Its massive body thrashed violently on the ground, and the surrounding black iron fragments flew wildly. However, because its joints were frozen by the Law of Stability, they couldn't form an effective attack.

Lin Yue took the opportunity to circle behind the Mysterious Iron Lizard. He discovered that its tailbone emitted strong fluctuations of the Metal Law—that was the core area controlling its Metal Law!

Without hesitation, he circulated his Chaos Energy, guided the scattered black iron fragments around him, and condensed them into a sharp "Fragment Blade." The Fragment Blade gleamed with a cold, sharp light. Lin Yue gripped the Fragment Blade and, with all his might, slashed fiercely at the Mysterious Iron Lizard's tailbone.

"Crack!"

With a crisp sound, the Mysterious Iron Lizard's tailbone snapped. The dense aura of the Metal Law instantly dissipated. Deprived of the law's support, the Mysterious Iron Lizard struggled for a few moments, its massive body gradually stiffening, and finally turned into a pile of ordinary black iron, leaving only a silver-glowing "Metal Law Fragment" suspended in mid-air.

Lin Yue walked forward and picked up the Metal Law Fragment. It felt cool to the touch, containing pure Metal Law energy. He could feel that this fragment would be of great help in refining spiritual treasures in the future.

"Finally dealt with," Su Qingyan sighed in relief and walked to Lin Yue's side. She looked at the black iron on the ground, a hint of regret in her eyes. "What a shame about so much black iron. If only we could bring it back to refine spiritual treasures."

Lin Yue nodded and took out an empty jade box from his storage bag, collecting the black iron fragments from the ground. "Although this black iron is ordinary, it's still a rare refining material. It might be useful if we take it back."

After a simple tidy-up of their spoils, the two continued deeper into the secret realm. They knew that more treasures and dangers awaited them, and they had to improve their strength quickly to face the challenges ahead.
