In those years when I was a mortal and a demon

Through several exchanges, Lu Yuan had already guessed that Lei Yunzi's 'Phantom Thunder' could not be used continuously, otherwise he wouldn't have waited two or three days each time before daring to leave the sea of ​​thunder.

Lei Yunzi's face was deathly pale, and the lightning power within his body was in disarray due to the dual suppression of his physical body and primordial spirit. Faced with such a desperate situation, it ignited his ruthlessness. With a flick of his wrists, he directly flung out several lightning beads.

As soon as these lightning orbs were thrown out, they exploded instantly, and lightning patterns of various shapes intertwined in the air to form a net. The power they released made Lu Yuan exclaim in shock, "This guy is courting death!"

In such a confined space, these thunder beads were enough to blast the thundercloud seed into ashes.

After guessing Lei Yunzi's identity, Lu Yuan gave up the idea of ​​killing him, since this guy would have to cooperate with Han Li again in the future.

Otherwise, when he was trapped earlier, Lu Yuan could have killed him on the spot at some cost.

But at this moment, with Lei Yunzi acting so recklessly, Lu Yuan had no choice but to temporarily avoid his sharp edge.

The mountain giant retracted its four arms, alternating them to protect itself in front of it, and withstood the explosive power of the thunder pearl.

What Lu Yuan didn't expect was that Lei Yunzi also had a backup plan. The moment the lightning pattern exploded, his body blurred and turned into countless bolts of lightning that shot out in all directions.

Several loud booms resounded, and thunderclouds of various colors appeared, covering an area of ​​several acres. Countless arcs of electricity as thick as bowls flashed and bounced wildly within them, even causing a nearby hurricane to rise into the sky. The continuous thunder and explosions seemed to engulf everything within them.

The scale of the event was so immense that it seemed as if the sky were collapsing and the earth were splitting apart!

In a short while, the huge thundercloud was swept away amidst the roar.

As soon as the thunderclouds disappeared, the electric arcs vanished, and the mountain giant reappeared.

But at this moment, the mountain giant looked rather disheveled, its four foremost arms charred black. The continuous use of its supernatural powers had already depleted the mountain giant's magical energy, leaving it only able to withstand the attacks with its bare body.

A thousand feet away, countless bolts of lightning converged at one point, and Lei Yunzi staggered out, but his condition was even worse. His aura was weak, and his clothes were tattered; clearly, his previous reckless actions had taken a heavy toll on him.

A cold glint flashed in Lu Yuan's eyes. Taking advantage of Lei Yunzi's weakness, several avatars pounced on him together. At the same time, his main body also pushed the power of the Purgatory Tower to its limit. Five-colored rays of light coiled around Lei Yunzi like a dragon, determined to take him down completely.

Seeing this, Lei Yunzi's eyes flashed with determination. He once again forcefully activated the remaining lightning power in his body, and his figure transformed into a thin bolt of lightning, rushing desperately towards the sea of ​​lightning.

However, he was now at his limit and his speed was far less than before.

The two avatars, the Rending Wind Beast and the Azure Phoenix, known for their speed, caught up with him in an instant.

The Rending Wind Beast spread its wings, its sharp claws like hooks, aiming straight for Lei Yunzi's back; the Azure Phoenix let out a clear cry, its azure feathers turning into swords, transforming into a net of swords that enveloped Lei Yunzi.

Lei Yunzi gritted his teeth and endured it. Unable to activate his magic weapon in time, he could only keep throwing out one thunder pearl after another to defend himself.

But at such close range, the aftershocks of the explosion also affected him, making him stagger and look even more disheveled.

Lu Yuan's original body seized the opportunity to catch up and smashed down the Purgatory Tower. Just before Lei Yunzi was about to enter the sea of ​​thunder, five-colored rays of light instantly enveloped Lei Yunzi, trapping him firmly.

"You forced me to do this!"

Lei Yunzi struggled in vain, then suddenly made several hand seals and roared, "Thunderous Myriad Swords!"

In an instant, several lightning arrays within the sea of ​​lightning revived simultaneously, and thousands of lightning bolts condensed into sword shadows, roaring out of the sea of ​​lightning and sweeping towards Lu Yuan and his several avatars like a storm. Each bolt contained the power to destroy mountains.

This power immediately caused Lu Yuan's expression to change drastically. His several avatars were all practicing demonic arts, and even though they had reached the Integration level, they could only exert less than 30% of their strength under the suppression of spiritual energy.

Faced with such fierce thunderous power, it is feared that it will not be able to withstand it for even a moment. Now, the only option is for Lu Yuan's unrestrained physical body to withstand this thunderous sword.

But before Lu Yuan could make a move, those thunderous sword shadows surged towards him like a tide.

The foremost Purgatory Tower held out for only a moment before being engulfed by countless lightning sword shadows, emitting a piercing roar, and then lost its mental connection with Lu Yuan.

Lei Yunzi, who was trapped, took the opportunity to escape and plunged into the sea of ​​thunder without looking back.

The terror of the Thunderous Thousand Swords far exceeded Lu Yuanzhi's imagination; one wrong move and even his own body would perish here.

Seeing thousands of thunderous sword shadows crossing the Purgatory Tower and heading towards him and his several avatars, Lu Yuan decided to go all out.

He clasped his hands together in front of his chest, then separated them, revealing a golden gourd about a foot tall.

"Open!" Lu Yuan slammed his right palm onto the gourd.

Instantly, countless golden runes appeared at the mouth of the gourd, spewing out streams of crimson-gold lightning that instantly transformed into a golden lightning net, colliding fiercely with the lightning sword shadow and unleashing a deafening roar.

The several avatars took the opportunity to leave, as they were powerless against the massive amount of lightning power.

"Chaotic Golden Lightning!"

Lei Yunzi, witnessing this scene in the sea of ​​thunder, widened his eyes in disbelief.

But soon, his lips moved slightly, and he suddenly spat out several mouthfuls of blood essence, which merged into the lightning arrays. As the blood essence merged, the lightning arrays shone brightly, stirring the sea of ​​lightning and shooting out even more lightning sword shadows.

After doing all this, Lei Yunzi released a small boat enveloped in lightning, and then collapsed onto it like a deflated balloon.

"With Lei Hai as my backup, you are doomed!"

As expected, although Lu Yuan's golden lightning net could withstand the attack for a while, it gradually became overwhelmed by the continuous lightning sword shadows in the sea of ​​lightning.

Lu Yuan's expression grew increasingly solemn. He made a series of hand seals with his left hand and kept chanting incantations.

In the blink of an eye, many colorful and radiant spiritual clouds gathered around it.

"To be able to mobilize the spiritual energy of heaven and earth here, you are not from the Demon Realm!" Lei Yunzi, who had witnessed this scene, suddenly exclaimed.

But Lu Yuan had no time to pay attention to him. With the help of the energy of heaven and earth, he slapped the gourd with his palm again.

The gourd trembled, but this time it spewed out not chaotic golden lightning, but a large expanse of misty fog, within which lightning flashed faintly, complementing the golden lightning net, and showing signs of gradually stabilizing the situation.

Upon seeing this, Lei Yunzi's expression changed. Unwilling to give up, he forced himself to expel blood again.

"You're asking for death!" Lu Yuan sneered.

The several avatars that had originally fled returned, each injecting their soul power into the mountain giant. Then, a flash of demonic light appeared behind the mountain giant's head, and its second nascent soul emerged, striking towards the golden gourd.

Amidst the blinding golden light, the Immortal-Slaying Flying Knife, dormant for hundreds of years, reappeared in the world.
