The two stepped into the Sixth Heaven, and what met their eyes was a ten-thousand-foot lightning bolt tearing through the Void Realm.

Seventy-two profound iron mountains hung upside down from the purple sky, and on the peak of each mountain was a hundred-foot lightning pillar. Purple-black electric pythons coiled around the mountain bodies, scorching the ink-jade-like rock walls with molten gold cracks. The ravines were not flowing water, but liquid lightning plasma. Whenever two lightning waterfalls collided, they exploded into thousands of skull-shaped electric sparks. At the mountain peak, leveled by the lightning storm, stood the bronze giant statue of the ancient Thunder Lord—the lightning orb held in his palm continuously collapsed and expanded, each pulsation causing a hundred thousand purple lightning bolts to strike down. Scattered among the scorched earth were vitrified weapon fragments. When the lightning swept over, these dead objects would emit a mournful shriek like that of the dying, as if sealing the despair of countless lost souls.

Suddenly! A deafening roar came from the clouds, and a purple-winged Sky Tiger with a wingspan that blotted out the sky tore through the lightning curtain, its golden eyes locked onto Su Meier: "It's actually a Nine-tailed Sky Fox! Hahahaha!! A Sky Fox dares to step into my lightning prison!!"

It turned out that the Sky Tiger and Sky Fox clans were mutually opposing, and their inner cores were both treasures to each other. Compared to ordinary Heaven And Earth Treasure, their inner cores seemed to be naturally made for the other. Swallowing the inner core would allow for extreme absorption of the other's Spiritual Qi and cultivation. Due to the Sky Tiger clan's powerful strength, the Qingqiu Sky Foxes had been in a disadvantaged position for thousands of years, mercilessly hunted down.

"Roar!!!" After a thunderous roar, the purple-winged Sky Tiger landed!

Only then did the two clearly see its ten-foot-tall body, like a moving mountain, with bulging muscles under its dark purple fur, gleaming with a metallic cold light. Four pairs of bone wings protruded from its spine, each wing membrane covered with blood-colored lightning patterns, stirring up hurricanes imbued with electric blades when flapped. Deep within its amber vertical pupils, magma-like ferocity pulsed, and the inverted lightning beast eye on its forehead continuously shot out purple electricity, illuminating the surrounding hundred feet like a ghost realm of hell.

Sword-like fangs hung with corrosive saliva, and where it dripped, highly poisonous green smoke rose from the ground. Its tiger claws were as large as millstones, with undried flesh and blood residue intertwined between its toes. The most terrifying was its steel whip-like tiger tail—the tailbone had twenty-four protruding barbs, and at the end was a deformed fleshy tumor covered with sharp teeth. Embedded in the center of the tumor was half of an undigested Nascent Soul Cultivator's skeleton.

"Roar!!!"

The purple-winged Sky Tiger roared at the sky, and ten thousand lightning bolts erupted from its crown, forming a lightning prison armor on its fur. The seventy-two suspended mountains trembled in response. Its tiger claw, imbued with lightning plasma, struck down towards Su Meier. Ling Tian used Instantaneous Movement to flash in front of her, and the moment the jade dragon sword blocked, dazzling electric sparks erupted. Ling Tian's tiger mouth cracked, and the rock layer beneath his feet collapsed like a spiderweb. The melted profound iron from his boots mixed with the lightning plasma, forming a crimson molten flow.

Su Meier displayed all nine of her tails. The Moonlight chains had just wrapped around the Sky Tiger's hind leg when it swung its tail and smashed her towards the cliff. The ferocious fleshy tumor at the end of its tail scraped against the mountain, actually pulverizing half of the mountain peak!

"Meier! The Sky Tiger's main target is you! From now on, you assist me from behind me! You must not be exposed within his line of sight," Ling Tian coughed up blood and threw out an ice escape talisman. Their figures instantly moved to the Sky Tiger's back.

"Dragon Spirit! Transform! Golden Dragon's Roar to the Heavens!!"

The jade dragon sword, imbued with Flame Dragon Fire, stabbed towards the densest lightning patterns, but then the bulging muscles there suddenly split open into a vertical eye. The purple lightning beam that shot out blasted him into the mountain belly. The entire suspended mountain melted into a vitrified waterfall in the lightning storm, and Ling Tian's charred body floated up in the crimson molten lava.

"Brother Ling Tian!" Su Meier used Instantaneous Movement to arrive beside Ling Tian and helped him up.

Su Meier formed hand Seals, and the qingqiu imperial seal appeared on her forehead. Her nine tail tips pierced into the rock veins to draw Spiritual Qi, and fox fire condensed into a hundred-foot-long Moonlight giant blade: "Qingqiu Secret Technique · Mountain Severance!" The blade light split the thunderclouds, but it was strangely repelled when it touched the vertical eye on the Sky Tiger's forehead, instead slicing the distant bronze giant statue in half at the waist.

"Petty tricks!" The Sky Tiger's four wings spread angrily, and lightning plasma condensed into a ball between its fangs. When the lightning ball expanded to a hundred feet, it suddenly exploded, sending out a hundred thousand arcs of electricity like a torrential downpour. Ling Tian's barely sustained Burning Sea fire shield instantly became riddled with holes, and Su Meier's Moonlight Barrier evaporated completely within three breaths.

Dangerous killing moves followed one after another. The Sky Tiger transformed into a lightning afterimage, and the fleshy tumor at the end of its tiger tail suddenly opened a ghostly eye. Eerie green ghost fire condensed into solid chains, wrapping around Su Meier's ankle. Just as she was about to be dragged into the tiger's mouth, Ling Tian's dragon-transformed right arm swung out a vacuum Sword Qi, severing the chains and saving Su Meier.

"Mere ants!"

The Sky Tiger spread all four wings, and the entire lightning prison transformed into a boiling furnace. The seventy-two suspended mountains erupted with sky-reaching lightning pillars, weaving into a lightning cage in the sky that imprisoned all things. Ling Tian had just flashed to avoid the tiger claw when the rock layer beneath his feet suddenly melted into a crimson vortex, and lightning plasma wrapped around his legs like venomous snakes—it was the Sky Tiger refining the ten-mile radius of earth veins into a lightning pool!

"Qingqiu Moon Guidance!"

Su Meier held essence blood in her mouth, using the power of the emperor seal to draw in Lunar Star Power. The moment the Moonlight collided with the lightning storm, three suspended mountains exploded with a roar, and the splashing lightning crystal fragments transformed into a hundred thousand blades. Ling Tian flashed into the air, his dragon-transformed right arm gripping the jade dragon sword and piercing through the lightning pool from top to bottom. Flame Dragon Fire flowed along the sword's edge into the earth veins. The entire lightning pool suddenly reversed, trapping the Sky Tiger in its self-made lightning plasma tsunami.

"Petty tricks!" The vertical eye on the Sky Tiger's forehead suddenly detached and flew out. The lightning beast eye hung in mid-air, spinning frantically. The lightning plasma, engulfed by the sea of fire, actually flowed backward into the sky, condensing into several lightning Dragons that lunged. Ling Tian swung his sword, shattering five lightning Dragons, but the sixth hidden one bit into his waist and abdomen. The lightning storm erupting from its Dragon teeth instantly carbonized half of his body.

"Forbidden Technique! Moonlight Cage!" Su Meier spat out a mouthful of fresh blood, forcefully using a forbidden technique to trap the Sky Tiger in a profound ice cage. Then, she tore off the ice-fire twin talismans hanging at her waist and launched three consecutive ice-fire combined attacks at the Sky Tiger's head!

"Burning Body!"

"Burning Sea!"

"Dragon Spirit! Transform! Golden Dragon's Roar to the Heavens!!"

How could Ling Tian miss the opportunity Su Meier had created with her life? He instantly went all out! Countless Sword Qi imbued with Flame Dragon Power slashed towards the Sky Tiger!

Just as countless Flame Dragon Fire were about to engulf the Sky Tiger, it suddenly stood upright and roared at the sky!

Then, a ten-thousand-foot lightning waterfall descended from the Nine Heavens. The tiger's body, bathed in lightning plasma, twisted violently, and the sound of cracking bones was like a hundred bronze bells ringing in unison. The four pairs of bone wings were the first to complete their metamorphosis—the surface of the purple crystal lightning wings bristled with countless inverted barbed lightning cones, and at the end of each lightning cone floated an extremely compressed lightning core. The original dark purple fur completely peeled off, and the newly grown profound black tiger skin flowed with liquid lightning patterns.

Next, the lightning beast eye on its forehead split into nine layers of pupils, each layer reflecting a different form of Lightning Tribulation: the outermost layer was a light green Yimu Lightning, followed by scorching white Gengjin Lightning, eerie blue Guishui Lightning, fiery red Lihuo Lightning, until the core, the pitch-black World-Ending Tribulation Lightning. Its tiger maw split to its earlobes, and its fangs evolved into two spiral sharp cones entwined with lightning Dragons. The liquid dripping from its teeth was no longer poisonous saliva, but highly concentrated lightning mercury, each drop corroding a three-foot lightning pit upon falling to the ground.

Rhombic lightning crystals protruded from its limb joints, and within the crystals, complete Dragon Spirits were sealed. Its tailbone extended into nine segments of lightning bone, and the deformed fleshy tumor at the end evolved into a lightning warhammer. From the bottom of the warhammer hung a hundred thousand chains condensed from lightning souls.

"Roar!!!"

The Sky Tiger raised its head and let out a long roar, and the Laws of the entire lightning prison resonated. The seventy-two suspended mountains decomposed and reassembled, forming a lightning crown behind it; the earth vein lava rose into the air, transforming into nine lightning Dragons coiling around a throne; even the striking Tribulation Lightning twisted into kneeling lightning spirits. At this moment, it was no longer a Yao Beast, but a tyrannical deity wielding control over the lightning prison.

"My name is—Thunder Lord."
