The passage within the tunnel was soon filled with a series of clanging sounds, explosions, and the noises of various traps.
Following this, a puff of green smoke emerged, a highly toxic substance that, if allowed to spread, would likely poison the soldiers.
However, for Zhou Yan, there were many ways to deal with such poisonous gas. He remembered an item in the warehouse that was very effective against it.
"Found it!" Zhou Yan retrieved the item and exclaimed, "Super Vacuum Cleaner, suck it up!"
Zhou Yan took out a vacuum cleaner-like device and began to suck in the poisonous gas. As the vacuum cleaner emitted a "whirring" sound, the gas was completely absorbed.
"Lord, what kind of artifact is this? It looks quite impressive," Yan Chixia remarked, his eyes shining.
"This isn't an artifact at all. It's used for cleaning dust from the ground. This particular one I have is just a more advanced model, so absorbing this poisonous gas is no problem," Zhou Yan replied.
After a long while, there wasn't a trace of poisonous gas left in the entire tunnel. Zhou Yan announced, "Let's proceed!"
They ventured further in and discovered various hidden mechanisms and traps. Zhou Yan condensed his spiritual energy and unleashed a punch the size of a basketball, shattering everything in front of them.
All sorts of hidden weapons littered the ground, and there were quite a few of them. It seemed the tomb's owner strongly disliked intruders.
The passage stretched for a full kilometer, with countless murals carved into the stone walls. Zhou Yan had no interest in deciphering their meaning. They soon encountered another large black iron gate, from which emanated a chilling aura even more intense than before.
Bai Qi and the others stepped forward, ready for battle.
Zhou Yan surveyed the black iron gate and commanded, "Open it!"
Wu Song, Bai Qi, and other heroes stepped forward and pushed with all their might against the heavy iron gate. It took all their strength to slowly pry it open.
As the ancient door creaked open with a series of groaning sounds, a hellish aura rushed out!
"Alert!"
Bai Qi and his men stood their ground, sensing an extraordinary presence. A powerful, unfathomably deep yin energy emanated from within.
Bai Qi and the others moved inside, with Zhou Yan and his entourage following. They entered a vast palace adorned with countless dragon pillars, each carved with a mighty dragon. These pillars stretched endlessly into the darkness, where the air was exceptionally strange.
They seemed to have reached the core area, resembling a true subterranean palace of the underworld.
"Stop!"
Zhou Yan raised his hand and then summoned over a hundred luminous crystal spheres that floated in the air. They then saw rows upon rows of soldiers standing before them, densely packed and radiating a chilling aura.
These were soldiers formed from yin energy. Their sheer numbers explained the terrifying presence they had felt.
The yin soldiers were arrayed in perfect order, standing motionless like statues.
"Swish, swish, swish!!!"
Suddenly, the yin soldiers opened their eyes, revealing a blood-red gaze. In unison, they raised their weapons and roared, "Kill!"
"Form ranks!" Bai Qi commanded immediately.
The soldiers began to form their battle formations, with Chen Qingzhi taking command of this white-robed army, the only one capable of unleashing their full might.
"Thump, thump, thump!!!"
The sound of heavy footsteps echoed as the yin soldiers in front began to advance towards them. Their numbers were overwhelming, and it was impossible to know how many more lurked in the darkness.
They were equipped like regular soldiers, with various weapons, armor, helmets, shields, and bows. Many yin soldiers even rode warhorses materialized from yin energy!
Zhou Yan glanced behind them and heard similar footsteps. Then, they heard the deafening sound of a gate slamming shut.
"Lord, countless yin soldiers have appeared behind us as well! We are surrounded!" a soldier reported.
"Lord, if I'm not mistaken, that large gate has been sealed. Should we ask Minister Zhang Liang to send reinforcements?" Yan Chixia asked, feeling a lack of confidence at the sight of so many yin soldiers.
"What can a few minor yin soldiers do to me!"
Zhou Yan showed no fear, drawing his Heavenly Soul Sword. A powerful sacred aura erupted, unleashing boundless holy light.
Combined with the Heavenly Soul Sword, which dealt bonus damage to soul-based monsters, these yin soldiers were already showing signs of fear as the sacred artifact appeared. It was a sacred weapon with soul-damaging properties, naturally making them apprehensive.
However, these yin soldiers were not simple. Zhou Yan could sense several powerful, cold presences lurking in the depths of the darkness, their strength far surpassing these common soldiers.
As a yin soldier's horn sounded, the troops began to charge at them rapidly.
"Kill!"
Zhou Yan gave the order and leaped forward, transforming into a beam of light. Wielding the Heavenly Soul Sword, he unleashed a terrifying sword aura and charged towards the incoming yin soldiers with a fierce strike.
A sword light, hundreds of meters long, descended, annihilating countless yin soldiers! Zhou Yan employed the "Lingbo Weibu" movement technique, darting like lightning into the endless yin soldier army.
His strength was unparalleled, his combat power astonishing. Single-handedly, he broke through the yin soldiers' formations and swept towards their archers.
"Open the battle formation and follow me to kill!" Chen Qingzhi and the others did not lag behind. They activated the full charge formation of the [White Robe Ghost Soldiers] and, led by Bai Qi, Chen Qingzhi, Meng Yi, Wu Song, and Yan Chixia, formed an arrowhead, charging ferociously forward!
They plunged into the yin soldiers, their immense impact penetrating hundreds of meters, annihilating countless enemies and leaving behind piles of soul boxes on the ground.
At this moment, he revealed his formidable "God of Slaughter" profession. He transformed, enveloped in streaks of blood-red energy, his eyes also turning blood-red.
Wielding his long sword, he became a crimson streak of light, charging into the yin soldiers. Wherever he passed, they vanished into thin air.
He raised his red sword and unleashed a cloud-like crimson energy, resembling the glow of sunset.
"Boom!"
The blood-red mist transformed into a blood-red ocean, surging towards the yin soldiers. Those engulfed by the energy cried out in agony before turning to ashes.
