"A pre-celestial spiritual treasure," True Monarch Xuanyuan transmitted through voice, and in the blink of an eye, retrieved an object radiating intense spiritual energy from his storage bracelet: "If you are willing to swear a blood oath in front of all your subordinates, this Glazed Hall, a pre-celestial spiritual treasure, will be yours."

The Glazed Hall? Lei Dong was momentarily stunned. He hadn't expected that this Xuanyuan would actually be willing to bring out a pre-celestial spiritual treasure. No, this was utterly impossible; there must be a trick to it. Perhaps Xuanyuan genuinely wanted to beg for safe passage with a blood oath, but there was no way he would willingly offer a pre-celestial spiritual treasure. Nevertheless, even so, Lei Dong couldn't help but extend his divine sense toward the treasure for a quick scan.

It was indeed an object resembling a hall, exquisitely crafted, emitting a glazed, luminous radiance. Judging by the faint aura and dense spiritual energy it radiated, it appeared to be something truly extraordinary.

Pre-celestial spiritual treasures—Lei Dong not only possessed one himself but had also witnessed several others. For instance, his Master's Nether River Diagram, the Hidden Dragon Pendant he had once acquired, and the Nether Ghost Emperor's Nether Black Fiend Array.

Each possessed different appearances and functions, yet they shared one commonality: they were all refined using the primordial Chaos Qi. The so-called Chaos Qi was a miraculous spiritual energy that existed from the very dawn of the universe. Chaos Qi was the legendary most fundamental spiritual energy of the cosmos, nurturing all manner of materials and life forms, each possessing incomparably miraculous or formidable qualities. Chaos Qi was also the mother of all things; the saying, "First Chaos, then Heaven and Earth," was not spoken in vain.

Materials such as Chaos Essence Iron, the Jianmu tree, or the Source of the Five Elements were all excellent materials for forging magical artifacts. Furthermore, various divine beasts and the Giant race that once dominated the desolation era appeared to have been born drawing upon this primordial spiritual energy.

From this, one could see how extraordinary Chaos Spiritual Qi was. Any manifestation of Chaos Spiritual Qi or its direct products were resources fiercely contested by various races. But after prolonged depletion, both Chaos Spiritual Qi and Chaos artifacts had become exceedingly rare in the current world; countless cultivators might never encounter even a sliver of it in their lifetimes. The existing pre-celestial spiritual treasures were all inherited from ancient times or unearthed from some ancient battlefield or ruin. The sole shared trait was that any pre-celestial spiritual treasure containing even a trace of a Chaos product would emit wisps of the Chaos aura.

As Lei Dong’s divine sense swept over it, he was startled. The Glazed Hall brought out by True Monarch Xuanyuan seemed to genuinely possess a faint, hazy aura of Chaos. Could it be that this object truly was a pre-celestial spiritual treasure?

Even with Lei Dong’s composure and intellect, he couldn't fathom Xuanyuan's true intentions for a moment. Giving up a pre-celestial spiritual treasure was an absolute impossibility. But if he offered such a treasure, wasn't he risking Lei Dong attacking without regard for casualties, fighting to the death?

As Lei Dong pondered doubtfully, True Monarch Xuanyuan suddenly laughed with a sinister expression: "Boy, I knew you couldn't resist probing it with your divine sense. The Ancient Arena has already recorded your divine sense imprint; your doom is sealed. Hahaha~"

The Ancient Arena?

The moment Lei Dong heard the name, it struck him as utterly foreign. This object wasn't the Glazed Hall? What use was it in recording his divine sense imprint? Regardless, this object was a pre-celestial spiritual treasure and surely possessed immense power. Reinforcements for the other side were arriving continuously, and even the Vespids were rapidly approaching.

At this juncture, Lei Dong resolved to disregard any further casualties. He roared, "Everyone, kill~"

The ones who heeded Lei Dong's command most readily were the young warriors of the (Hidden Dragon Army). They immediately drew their magical artifacts and charged forward fearlessly. Next were the Earth Giants. Their thinking was simple: Lei Dong held command over them, and they were bound to obey, even if it meant marching to their deaths. Before they could even form ranks, they condensed massive stones, which hurtled toward the Taishang Sect members.

The Ghost race and the Yaksha race, after a brief pause, also sprang into action obediently. Although the enemy possessed a Nascent Soul-level expert, their overall strength seemed slightly superior to their own side. While they could deduce that this fierce battle would result in heavy losses, these two races were inherently fearless. Since the order to attack had been given, any number of casualties must be accepted.

"Damn it," True Monarch Xuanyuan's face changed drastically as he inwardly cursed himself for getting carried away; why show off? His original intention was merely to flaunt his power briefly before dragging Lei Dong into the Ancient Arena for a focused annihilation. Without Lei Dong, their apparent overall commander on the battlefield, the various races beneath him would simply be scattered sand.

However, True Monarch Xuanyuan never expected this brat to react so swiftly, issuing the attack order immediately. Without daring to delay any further, he pointed a finger at the model-like Ancient Arena while shouting, "As fast as the law commands! I, True Monarch, offer a fair battle to the death with this boy! Ancient Arena, activate quickly!"

A magical event transpired. The hall-like Ancient Arena expanded rapidly, soaring into the sky in the blink of an eye, growing to several hundred zhang tall, and still continuously swelling. Lei Dong, at this moment, cared little for what this infernal thing was. His expression as grim as still water, he commanded in a deep voice, "Everyone, regardless of what happens, attack! Attack and exterminate every member of the Taishang Sect!"

Simultaneously, Lei Dong began to retreat, his form moving backward like a phantom toward the group of Earth Giants. Their massive size and inherent combat prowess gave Lei Dong a sense of security.

But before Lei Dong had retreated even a few dozen zhang, an immensely authoritative and powerful aura locked onto him firmly. At the same time, a thunderous voice resonated directly within his mind: "I am the Fair Arena. The human Xuanyuanzi has issued a forced life-or-death duel against you using a Fair Oath. In three breaths, you will be teleported into the Arena."

A sense of horror washed over him. What 'Fair Arena'? He didn't understand what it was, but Lei Dong intuitively felt it couldn't be anything good. However, no matter how Lei Dong dodged or weaved, that powerful pressure locked onto him like maggots clinging to bone.

As expected, after a few breaths, Lei Dong felt a force too immense to resist envelop him tightly. The space around him twisted violently, and his vision blurred before he materialized suddenly within an unfamiliar dimension.

It was a vast plain, stretching as far as the eye could see, a battleground. Lei Dong hovered in mid-air above the plain, looking down to see the entire expanse paved with massive, unknown stones. It exuded an ancient and desolate atmosphere.

Perhaps due to countless battles, the platform resembling an arena was dilapidated and worn, scarred by numerous craters and sword marks. The sky above was gloomy and obscure, the fierce wind relentless, with faint hints of lightning flashing, instilling an indescribable sense of dread upon sight. It seemed direct flight to escape into the clouds would not be possible.

Just then, several dozen zhang in front of Lei Dong, space fluctuated, and True Monarch Xuanyuan slowly appeared.

A chance! Lei Dong had always been ruthless. Seeing that Xuanyuan had been teleported in after him, how could he not seize the opportunity? He immediately channeled all his power and unleashed a Black Dragon's Roar.

The black dragon was vivid and lifelike, roaring as it was about to strike Xuanyuan, when a transparent energy shield materialized before him, easily blocking the potent Black Dragon's Roar.

"Human cultivator, a warning: do not think of playing tricks within this Fair Arena. Remain where you are, and only attack once the life-and-death competition officially begins," the thunderous voice echoed directly in his mind.

Lei Dong was momentarily taken aback, but he was also a man of extensive experience; having gone through transmigration, what else could be considered impossible? He immediately asked, "May I ask the Fair Arena, what exactly constitutes a 'Fair Life-or-Death Competition'?" Judging by the entity's tone, there was a hint of mechanical inflexibility, suggesting it was highly likely not a powerful living being but an entity akin to an artifact spirit. Artifact spirits often adhere strictly to established logical parameters and do not engage in deceit.

"The Fair Arena is an independent combat space refined by the Master to resolve conflicts and disputes between races. Within this Arena, all battles are conducted adhering to the principle of absolute fairness."

"Can I ambush? Can I use various tactics?" Lei Dong swiftly inquired, needing to gather as much information as possible in the shortest time.

"You may, but only after the formal duel commences," the artifact spirit replied coldly.

"Then, can I use any spells, talismans, consumables, magical artifacts, elixirs, armies, battle pets, ghost pets, or puppets?" Lei Dong pressed again, not wanting to consume an elixir only to be flagged for breaking the rules and potentially being erased by the Arena's artifact spirit.

"You may use any spells, talismans, consumables, and magical artifacts, and elixirs. You may use battle pets, ghost servants, puppets, or artifact souls bound by personal blood sacrifice contracts for the participant. However, you may not, nor will you be able to use subordinates, armies, family members, or friends controlled by any means. All final interpretations and judgments rest with this Fair Arena."

Lei Dong felt a slight relief, then knitted his brows again. He had initially considered dragging the Earth Giant clan in to assist, but it seemed impossible now. The benefit, however, was that he appeared able to use his ghost servants. He immediately said solemnly, "Very well. My ghost servant, Xiao You, please assist by being pulled into the Arena."

Although he hadn't had time to reminisce with Xiao You just now, he had noticed she had already reached the mid-stage Ghost King realm, her power greatly enhanced. Fortunately, the blood sacrifice contract between them had never been broken; in principle, she was still his ghost servant. It wasn't that Lei Dong wanted to drag Xiao You in to die; if he perished, Xiao You, bound by the blood sacrifice contract, would also have her soul instantly annihilated. It was better to fight together.
