Simultaneously, Ye Yunfei continuously unleashed Heart Sword, Mind Reading, and Soul Artifact spells, relentlessly attacking the old wizard's Soul Sea and Soul Body.
Gradually, the old wizard began to feel more and more pressure.
He had indeed encountered some special opportunities during this period, leading to a significant increase in his strength. Therefore, he was able to resist Ye Yunfei's various attacks for a while, unlike the last time when he was quickly rendered helpless and nearly perished after being besieged by hurricane-force winds and whirlwinds.
This time, he resisted for much longer and seemed somewhat more composed, but gradually, he began to feel the pressure mounting unbearably.
The power of Ye Yunfei's diverse attacks was simply too terrifying.
Furthermore, at this moment, the hurricane-force winds and whirlwinds created by Ye Yunfei had completely engulfed the entrance and exit of this world, making it extremely difficult for the members of the Guardian Faction to enter it.
Any member of the Guardian Faction who arrived at this location would immediately be trapped by the terrifying winds and whirlwinds, finding movement arduous before being captured alive by the Ghost Army and Corpse Army led by Huang Shang.
Seeing this, the Prison Master was both shocked and furious, but he was blocked by Elder Bi, given no opportunity whatsoever to rush over and deal with Ye Yunfei.
"Old fool, I advise you to stop this futile struggle. Today, the Guardian Faction faces only one outcome: annihilation," Ye Yunfei said coldly.
At this point, Ye Yunfei had gained the upper hand. Not only had he tightly sealed the world's entrance and exit, but he had also forced the old wizard into a steady retreat, clearly on the verge of collapse.
"You damned little beast surnamed Ye! Wiping out our Guardian Faction won't be so easy. At worst, we'll perish together!" the old wizard roared in anger.
"This guy really won't stop until he's faced with certain doom, still talking tough at a time like this!" Hu Miao couldn't help but sneer.
"Old Wizard! I'm here!"
Just then, a voice suddenly echoed from within that world, followed by an old man rushing out.
"Old Mo! You've finally come! Beware of those winds and whirlwinds!"
Upon seeing the old man, the old wizard's face lit up with joy, but he immediately shouted a warning.
"What is this?"
The old man had just rushed out from the world when he was enveloped by raging winds and whirlwinds. His robes were instantly shredded to dust, and bloody gashes appeared on the surface flesh of his body.
His face instantly changed color.
Then, above his head, a seemingly ancient and simple-looking War Drum materialized.
The old man took out a wooden club and fiercely struck the drum. A dull, booming drum sound erupted, releasing rolling sound waves that tore through the surrounding space like a vast ocean, surging upward and radiating outwards in all directions.
Though it was just a single drumbeat, it sounded as if a million-strong army was locked in battle, howling at the heavens and earth.
"Excellent! Old Mo, you really brought the War Drum! With this drum, it will surely ensure the safe retreat of our Guardian Faction army!"
The moment the old wizard saw that ancient War Drum, an expression of ecstatic joy appeared on his face.
What kind of treasure is this?
Ye Yunfei stared at the resonating drum in some surprise, sensing the terrifying sound waves it emitted and realizing it was a very powerful magic treasure.
"This is undoubtedly a Chaos God-grade treasure. Moreover, it belongs to the rare sonic-based category. Sonic treasures are scarce, but they are generally exceptionally potent," Hun Lao immediately spoke up.
Thump! Thump! Thump…
Another wooden stick appeared in the old man's other hand. Now wielding two sticks, he began continuously beating the ancient War Drum above his head.
The drumbeats multiplied, instantly conjuring the feeling of endless armies charging forth from within the drum.
Once sounded, each beat of the drum seemed to contain a profoundly mysterious rhythm, a rhythm so terrifying that it infected the Soul Bodies of all the Guardian Faction members present. Even the blood within their bodies began to surge and boil.
As the drumbeats continued, the Soul Bodies of every member of the Guardian Faction army began to glow, their blood burning with fervor. They felt an overwhelming desire to engage in a life-and-death battle.
What surprised Ye Yunfei even more was that the hurricane-force winds and whirlwinds he had created were actually being countered by those rolling drum sound waves.
"Wonderful! The drum can oppose the winds created by that little beast!"
The old wizard was incredibly moved by this sight, almost weeping for joy.
The pressure Ye Yunfei's winds and whirlwinds had placed on him was simply too great.
"Old Wizard, although the drum's power is formidable, the consumption of divine energy is immense. Even if the two of us join forces to beat it, I doubt we can sustain it for long. We must have the army retreat immediately," the other old man said, swinging his two sticks to beat the drum but quickly showing signs of strain.
Every time he struck the drum, a huge amount of divine energy was consumed. Only by continuously channeling vast amounts of divine energy into the drum could its power be maintained.
"Very well! I'll have the army seize this opportunity and retreat now!"
Seeing the other old man's expression, the old wizard's face paled slightly.
He knew this man's cultivation realm and strength were not inferior to his own. That he was already showing signs of fatigue after striking the drum for only a short time proved the drum's energy consumption was truly horrifying.
The old wizard then rushed to the other man's side, took one of the wooden sticks, and helped beat the drum.
With two powerful experts beating the drum together, the rhythm became denser, the sound louder, and the rolling sound waves whistled forth, standing in equal opposition to the hurricane-force winds and whirlwinds created by Ye Yunfei.
"Master, that treasure is quite impressive. It can actually oppose the winds and whirlwinds you created," Hu Miao said in astonishment.
"Splendid!"
At this moment, the Prison Master also revealed an expression of pleasant surprise upon seeing this.
Previously, he had felt despair, thinking the Guardian Faction army he led might be unable to escape, with most perishing. But now, with the arrival of the old man bearing the War Drum, the situation had changed.
The War Drum could counter Ye Yunfei's winds and whirlwinds, giving the Guardian Faction army a chance to flee.
"Huang Shang! Retreat immediately!"
Ye Yunfei suddenly noticed that Huang Shang's Ghost Army and Corpse Army were beginning to suffer attacks from the drum sound waves, with a large number being destroyed in a short time. He quickly called out a warning.
Huang Shang was also startled and hastily led his Ghost Army and Corpse Army into a steady retreat.
"Friends of the Guardian Faction, please help me detain this ghost cultivator. I wish to bring him back to the underworld to face judgment and admit his crimes."
Just then, a sinister voice suddenly rang out.
Immediately after, a figure shrouded in a swirling mist of overwhelmingly dark, Yin-cold aura appeared nearby.
With its appearance, the temperature in the surrounding space plummeted dramatically. Blocks of dark profound ice continuously materialized, suspended and colliding with each other, producing ringing sounds. Dark Yin-lightning also flashed intermittently.
Ye Yunfei had high attainments in the Ice Grand Dao Laws, but the aura this figure utilized was not of ice but rather a law of Yin-cold.
"It is a friend from the Great Netherworld!"
The old man beating the drum and the old wizard revealed expressions of pleasant surprise upon seeing this figure that had suddenly appeared.
"Esteemed friend from the Great Netherworld, our Guardian Faction headquarters is currently under invasion by a formidable enemy. That young beast's strength is considerable, and the Hunyuan Sect army before us also possesses considerable overall might. Could our esteemed Great Netherworld friend possibly lend a hand and assist us against this foe?" the old wizard tentatively asked.
"If you can help me capture this ghost cultivator, I can summon an army of Yin Soldiers to aid your Guardian Faction against the enemy," the voice shrouded within the Yin-cold aura spoke indifferently.
"Excellent!"
Upon hearing this, the old wizard and the other elder nodded simultaneously.
Then, they frantically channeled the divine energy within their bodies into the wooden sticks in their hands, beating the drum with even more maniacal intensity.
The rolling sound of the War Drum was like the roar of thousands of soldiers and horses, majestic and vigorous, akin to the impending return of an ancient war god, as if leading an army from the dawn of antiquity across primordial lands, carrying with it a thick aura of ancient wilderness.
Rolling thunderous sounds transformed into an ocean-like wave of sonic power that surged toward Huang Shang and the two armies he led.
Seeing this, Ye Yunfei hurriedly manipulated the Great Wind Stele and Wind Pearl to create more hurricane-force winds and whirlwinds, attacking the sound waves.
"I think I remember what that War Drum is! It must be a sacred artifact of the ancient Battle Clan! It is said that when this drum is beaten, it awakens the fighting will within members of the Battle Clan, allowing them to tap their potential, surpass their normal performance, and unleash astonishing combat power.
Who would have thought this War Drum has fallen into the hands of the Guardian Faction?"
Suddenly, Hun Lao spoke in astonishment.
He had just recalled this piece of information about the Battle Clan from his accumulated racial memories.
The Battle Clan?
Upon hearing Hun Lao's words, Ye Yunfei immediately thought of a girl he had known back in the Tianxuan Continent – a girl named Long Yingying.
Long Yingying was a member of the Battle Clan.
However, later, as Ye Yunfei continuously journeyed from one world to another, venturing into ever-vaster realms, he had lost contact with Long Yingying.
"Correct. This War Drum is most likely the sacred artifact of the ancient Battle Clan. The sacred artifacts of the Battle Clan can arouse the fighting will and fighting energy of living beings, allowing them to perform beyond their normal limits.
Look now. All the Guardian Faction members are brimming with battle intent, and each one's displayed combat power has increased significantly, mainly due to that War Drum," Hun Lao confirmed, nodding.
"Indeed."
Ye Yunfei assessed the current state of the Guardian Faction members within the World Cluster and found this to be true.
"Not good, Master! Huang Shang is trapped by those drum sound waves!"
Hu Miao suddenly cried out in alarm to Ye Yunfei.
"Don't worry. I'll help him!"
Ye Yunfei's figure blurred as he swiftly rushed toward Huang Shang's location.
"No passage through here."
However, before Ye Yunfei could get close to Huang Shang, two figures emitting Yin-cold auras appeared ahead, blocking his path.
The figure on the left held a white wooden staff, the one on the right, a black wooden staff.
