At that moment, a young man slowly emerged from another stone statue. His red hair flew wildly like flames, his eyes blazing with passion and fury, like two blazing flames. Flames and lightning mingled around him, seemingly unleashing boundless power. He wore red armor engraved with mysterious purple runes of fire and thunder. As the runes flickered, he exuded a terrifyingly powerful aura.

"I am Emperor Yan Lei, please take action! Becoming a god is not easy! Let me see whether you have the qualifications." Although Yan Lei looks like a young boy, he has an innate and unparalleled arrogance.

Seeing Yan Lei's personality, Yu Kai didn't feel resentful. He knew that the people before him were all top figures of their era, and naturally had the capital to be arrogant. Yu Kai bowed respectfully and said, "Please teach me, Senior."

As soon as he finished speaking, the magnificent mecha instantly enveloped him tightly, and the Moon Spirit Holy Sword appeared firmly in his hand. Without hesitation, he mobilized his spiritual energy and immediately unleashed his ultimate move. With the speed of a meteor, he unleashed the fifth form of the Moon Spirit Sword—Endless Life. His sword moves traversed like a nimble dragon, imbued with the might of sword intent and the power of laws, slashing directly towards Yan Lei.

Sensing the powerful sword intent emanating from Yu Kai, Yan Lei forgot his previous contempt. His figure was like a streak of lightning, instantly tearing through the sky and vanishing without a trace in the blink of an eye. The powerful sword intent slammed heavily into the ground, instantly creating a long gaping hole, sending rubble and dust flying.

Before Yu Kai could react, Yan Lei appeared before him like a ghost. Yan Lei raised his huge fist high, lightning swirling around it, making a crackling sound, and with terrifying power, he smashed it fiercely towards Yu Kai's face.

Yu Kai couldn't dodge, and could only quickly raise his mecha's left arm to block. "Boom!" With a resounding roar, the violent impact, like a raging torrent, sent Yu Kai flying. He slid across the square, retreating repeatedly, leaving a deep scar on the ground. His left mecha arm was completely shattered, its entire arm exposed, a bloody mess of flesh and blood dripping continuously.

However, Yan Lei didn't intend to give Yu Kai a break. With lightning speed, he pursued him. His iron fists rained down like a torrential rain, each one imbued with devastating force. Yu Kai was instantly passive, completely suppressed. Under Yan Lei's fierce and torrential attack, his mecha was shattered to pieces, his body covered in blood, and he looked utterly miserable.

"Boom!" Another powerful attack sent Yu Kai flying. Like a kite with its string cut, he slammed heavily into a nearby stone statue, then fell to the ground with a thud. Yan Lei stood proudly in the square, looking down at Yu Kai with disdain, saying, "With such limited abilities, you still dream of becoming a god!"

"Senior Yan Lei, you're tired and need to rest!" A voice suddenly sounded from behind him, startling Yan Lei, thinking to himself, "This is bad!" Before he could react, Yu Kai struck him with his sword. The powerful sword intent, like a sharp blade, sent him flying. A long, bloody scar was cut across his red armor, and blood flowed out.

Yan Lei looked at Yu Kai in front of him, then turned to look at the "Yu Kai" he had knocked away. He saw that "Yu Kai" had turned into a wisp of smoke and drifted away with the wind. "The Law of Dreams!" Yan Lei instantly realized that he had been deceived. He felt angry, surprised, and even more unwilling. He also reassessed Yu Kai's strength. He completely ignored his own injuries and rushed towards Yu Kai like an angry beast. A spear condensed from lightning instantly took shape in his hand and stabbed it fiercely at Yu Kai. Wherever the terrifying spear shadow passed, the surrounding void shattered, making bursts of "cracking" sounds.

Seeing this, Yu Kai hurriedly blocked it with his sword. With a ding, the sword deflected. The spear tip pierced the mecha unhindered, piercing directly into his chest. However, strangely, not a single drop of blood flowed. This scene further infuriated Yan Lei, who shouted, "Dream, still a dream!"

At that moment, Yu Kai's attack descended from behind him like a ghost. A powerful sword beam flashed in an instant, its light blinding the eyes. Though Yan Lei was prepared, Yu Kai's immense power still sent him flying. Before he could steady himself, another sword slammed down from the sky. Yu Kai's presence became increasingly elusive, attacking him from all angles, overwhelming Yan Lei. In a blink of an eye, Yan Lei's body was covered in wounds, blood staining his armor.

Yan Lei was utterly frustrated by the blow, and he was unwilling to give in just yet. "Ah!" He roared to the heavens, unleashing an even more powerful pressure. This pressure was incredibly violent, like an invisible storm, shattering Yu Kai's shadow.

"All heavenly thunderbolts, obey my command! Destroy the world!" With a furious roar, thunderclouds rolled wildly overhead, as if doomsday were approaching. Like the previous world-destroying thunderbolts, they descended upon Yu Kai. As if unable to withstand the overwhelming force, the surrounding space began to warp and deform, emitting a series of crackling sounds. The ground shook violently, and cracks spread rapidly like a spider web.

Yu Kai didn't dare to be careless, attempting to quickly retract his illusion. However, he was still a step too slow. His illusion was instantly shattered by the thunder, and Yu Kai suffered the backlash, spitting out a mouthful of blood. He endured the pain, dragging his heavy body, struggling to move through the endless thunder.

"Run! I'll see where you can run!" Yan Lei sneered and quickly cast a series of spells. Thunder dragons appeared out of thin air, claws and fangs bared, and pounced towards Yu Kai with great momentum.

Yu Kai looked at the thunder dragons filling the sky, knowing full well that dodging was futile. He steeled himself, thinking to himself, "I can fuse the Law of Gold, and you can absorb the world-destroying thunder tribulation. Why can't I absorb these thunder dragons? Today I will fuse them all and use this to break through to the Saint Emperor realm."

With this in mind, he abandoned his dodging, resolutely abandoning resistance and charging towards the swarm of thunder dragons. He pushed the Law of Thunder to its limit, and a thunder dragon rushed towards him first. However, at this moment, as if tamed by some mysterious force, the thunder dragon transformed directly into pure Law of Thunder and merged into Yu Kai's body. Immediately afterwards, one thunder dragon after another merged into Yu Kai's body. As each thunder dragon merged, his aura gradually intensified, and the lightning around him became more violent. Suddenly, an extremely powerful aura emerged from Yu Kai's body like a volcanic eruption, spreading wildly in all directions. He succeeded, not only resolving the immediate crisis but also breaking through his own realm in one fell swoop.

At this moment, Yu Kai was surrounded by lightning, his fighting spirit high, like the Thunder God descending to the earth. His eyes were as sharp as torches, staring intently at Yan Lei below, and he shouted loudly, "But we still have to fight!"
