The situation in the Yan Realm had been resolved, and naturally, Gu Fei wouldn't stay any longer.
With the current situation, the Yan and Lei clans- being the most powerful ancient clans after the Gu and Hun clans- would pose a great danger if infiltrated by the enemy.
There was no time to waste! He had to head to the Lei Realm immediately to investigate.
As he left, the Yan Realm erupted in chaos.
The news that Elder Huo Xiong had been identified as a Hun Clan spy spread like wildfire throughout the clan.
Fairy Huo Ling, knowing the gravity of the situation, immediately gathered a group of highly respected elders to begin a thorough investigation.
Inside a dungeon filled with scorching flames, Huo Xiong was tightly bound by iron chains. His once powerful physique now appeared weak, and his lifeless eyes stared blankly at the ground.
"Brother, do you remember what happened during our training back in the day?"
An elder with white hair slowly entered the dungeon, looking at Huo Xiong with a complex expression.
Huo Xiong trembled slightly at the question and lifted his head.
"Of course I remember, we trained together… together…"
His eyes flickered with confusion, and he quickly tried to regain his composure. However, his words faltered halfway, and sweat began to form on his forehead.
"How could you forget that? We trained for three years in that dangerous canyon!"
The elder sighed in disappointment, shaking his head.
Huo Xiong's face turned pale, and a trace of panic flashed in his eyes.
At that moment, another elder entered.
"Do you remember the name of the child we saved together?"
This elder stared at Huo Xiong with piercing eyes, his tone serious.
His body jolted, and a look of fear crossed his face.
"I... I remember…"
He stammered, but the elder scoffed.
"We never saved any child together."
With a cold snort, the elder's eyes filled with disappointment. As more questions were posed, Huo Xiong's responses became more and more erratic. His answers were full of inconsistencies, and he even failed to recall basic details.
"So, he really was from the Hun Clan!"
Anger and disappointment filled the dungeon.
The elders who had once been close to him now looked at him with a mix of pain and fury.
Realizing that his cover had been blown, he suddenly erupted with a surge of immense strength, breaking free from his chains.
"If that's the case, don't blame me for being ruthless!"
He roared, releasing a terrifying aura. Black flames surged from within him, enveloping the entire dungeon.
But just then, a cold voice echoed.
"Give up your struggle."
Fairy Huo Ling appeared at the dungeon's entrance, her face expressionless, with icy determination in her eyes.
Seeing her, a look of despair crossed his face. He knew he was no match for her.
"If I'm going down, I'm taking you with me!"
He let out a maniacal laugh as the energy within him became dangerously volatile. His body began to swell, as if he were about to explode.
"Courting death!"
She scoffed and extended her hand. Instantly, terrifying flames shot from her palm, engulfing him completely.
"Ahh!"
With a horrifying scream, Huo Xiong's body turned to ash in the blink of an eye.
In just moments, Fairy Huo Ling had executed the spy who had been hiding in the Yan Clan for so many years.
Meanwhile, Gu Fei had arrived in the Lei Realm.
Looking around, he saw strange trees shimmering with silver light everywhere. These were the Lei Clan's unique silver trees, not only capable of constantly channeling the power of thunder into the world but also serving as an important resource for the clan's cultivation.
Above, countless massive bolts of lightning surged through the clouds, accompanied by deafening thunderclaps. The entire realm was filled with a menacing aura of thunder that made one feel as though they could be struck at any moment.
Even the blackened rocks scattered throughout the realm seemed to have been scorched by frequent lightning strikes.
As Gu Fei marveled at the grandeur of the realm, a figure suddenly approached from the distance.
Upon closer inspection, the person was none other than Lei Dong.
"Brother, it's been a while."
Lei Dong greeted him warmly, clasping his fists in respect.
His sharp, lightning-like eyes flashed with a mix of joy and slight awkwardness, clearly pleased yet somewhat embarrassed by his arrival.
"The clan leader has instructed me to assist you with the task of rooting out the traitors. We are honored by your help, brother."
Lei Dong's tone was respectful and courteous.
Gu Fei nodded slightly, his gaze scanning his face.
He could sense that his attitude toward him had become much friendlier than before, likely due to his current status and power.
Naturally, Gu Fei didn't dwell on the past.
"You're being too polite. Let's begin."
He smiled faintly.
Lei Dong nodded and led the way as they walked and talked.
"Brother, do you think you'll succeed in this task?"
He asked curiously, still unaware of the true nature of his mission.
Gu Fei frowned slightly.
"No need to ask too much. You'll see for yourself soon."
He paused before adding, "But let me make this clear- I'm here to help you identify the spies, not to waste my time."
"I have my own methods. Whether or not you trust me is up to you."
His tone was calm but resolute.
When he helped the Yan Clan, many had doubted him. Even the spy had dared to question him directly.
Now, coming to the Lei Clan, he had to set expectations straight.
Soon, the two arrived at a grand hall deep within the clan's territory.
Countless arcs of lightning danced across the walls of the hall, crackling softly, giving the impression that anyone who misbehaved here would be struck down instantly.
"This is our clan's assembly hall."
Lei Dong pointed to the hall, his voice tinged with pride.
Gu Fei nodded and glanced around the hall.
He could sense the immense power of thunder contained within this place. Anyone who dared to act recklessly here would surely be turned to ash by the lightning.
Just as they were about to enter, hurried footsteps sounded from afar.
"Young Master, something terrible has happened!"
A panicked Lei Clan member rushed over, his face filled with urgency.
"What's the matter?"
Lei Dong frowned, clearly displeased with the man's lack of composure.
"It's the Yan Clan! They've just reported that they uncovered a Hun Clan spy!"
The man panted heavily, his voice filled with shock.
"You don't need to tell us that- brother Gu Fei is already here," he waved dismissively.
