Tribulation, Primordial Spirit Tribulation

"Snort."

Jiang Linglong snorted coldly and secretly pinched Chen Nianzhi.

Chen Nianzhi took a deep breath and quickly changed the subject, saying, "Since it's getting late, let's prepare to make our move."

Now that they were ready to take action, the group of fifteen True Lord all perked up and began to adjust their state in preparation for this battle.

A moment later, Chen Nianzhi and the other twelve True Lord joined forces, piloting the Treasure Ship with more than two thousand cultivators, and charged into the Subterranean Fire Vein, leaving only Chen Changxuan and two others to oversee the formation.

As soon as they entered the Subterranean Fire Vein, Chen Nianzhi noticed streaks of fire shooting towards them, and countless low-level fire demons swarmed out, continuously attacking them.

The Flame Demon King saw that they had more than a dozen True Lord, who were trying to use low-level Flame Demons to deplete their Law Power.

Seeing this, Jiang Linglong said to Lin Qianshu, "Qian Shu, act quickly."

"Clear."

Lin Qianshu nodded and instantly activated the Myriad Swords Void-Demon-Slaying Formation. In an instant, thousands of sword lights crisscrossed and swept across the battlefield, carrying unparalleled power to continuously annihilate countless Flame Demons.

In just one exchange, tens of thousands of fire demons were killed, instantly routing their opponents.

At the same time, thousands of the Purple Mansion cultivators also launched attacks against the Flame Demons from behind the Treasure Ship.

The battle lasted for three hours, and in the end, the Flame Demon was routed and forced to retreat.

Seeing the low-level Flame Demons scattered, Chen Nianzhi transformed into a sword light and charged out, shouting with murderous intent, "Attack!"

Seeing this, the twelve True Lord also rushed towards the core of the Subterranean Fire Vein. The Flame Demon King, seeing this, finally couldn't hold back any longer and came out with boundless murderous intent.

"Human Race, you are courting death."

A deafening roar resounded, and when Chen Nianzhi looked up, he saw five towering fire Demon God striding towards him.

They were remarkably similar to the Scarlet Flame True Lord from back then, except that their bodies were wreathed in jet-black demonic flames, and they were much taller.

The leader, the Flame Demon King, was three thousand feet tall, wielding a crimson spear that resembled a pillar supporting the sky, and coldly thrust it forward.

"Careful."

Jiang Linglong's gaze sharpened, and she summoned the Heavenly Ruins Immortal-Slaying Sword to block the attack, only to find that the Heavenly Ruins Immortal-Slaying Sword was sent flying backward.

"It's a companion Spirit Treasure."

Chen Nianzhi took a deep breath and joined forces with Jiang Linglong to deal with the Flame Demon King.

The Flame Demon King's companion Spirit Treasure is truly powerful. It was born from the fire element power within the Subterranean Fire Vein, and its grade is as high as the Tier 5 Upper Grade. Its killing power can be described as unparalleled in the world.

The two dared not be careless and could only go all out, unleashing all their magical Spirit Treasure to fight against the Flame Demon King.

The others weren't idle either; they methodically followed the battle plan, finding their opponents and aiming to eliminate them as quickly as possible.

Although the four Flame Demon True Lord were powerful, they were quickly overwhelmed by the combined attack of the crowd.

Yan Ziji and Lingxu Fairy worked in perfect harmony, quickly joining forces to attack the weakest of the Flame Demon True Lord.

Both of them were at the Nascent Soul Middle Stage realm, and with their combined strength, they easily forced it into a corner with nowhere to escape. Seeing this, Ya Ya unleashed the Ice-Soul Condensed Jade Pagoda and bombarded it.

"Ah--"

With a miserable cry, Flame Demon True Lord's physical body was shattered by the Ice-Soul Condensed Jade Pagoda. Upon seeing this, Yan Ziji immediately activated her Natal Great Divine Ability, the Purple Firmament Void-Slaying Saber, instantly severing Flame Demon True Lord's Nascent Soul in two.

"How dare you!"

In just a short time, one of the Flame Demon True Lord was killed.

The Flame Demon King immediately flew into a rage, wielding his crimson spear to strike the powerful enemy. He then unleashed his Natal Great Divine Ability "Flame Demon Blood Sword," which unleashed a burst of black and red sword light that slashed towards Ya Ya.

Do you really think I don't exist?

Chen Nianzhi snorted coldly and activated the Heavenly Separation Twin Swords Unity. In an instant, dazzling sword light crisscrossed the area, blocking the Flame Demon Blood Sword.

Jiang Linglong also acted simultaneously with perfect coordination, unleashing the Duality Divine Light to freeze the crimson spear.

"Ah--"

Seeing his attack falter, the Flame Demon King roared and relentlessly swung his spear at the two men.

Unfortunately, this demon's combat power was weaker than that of an ordinary Nascent Soul Late Stage. Its only redeeming quality was its inexhaustible Law Power within the Subterranean Fire Vein, but even that was no match for Chen Nianzhi and her companion.

With the Flame Demon King unable to provide support, Ya Ya and the others naturally went all out, seizing the opportunity to launch a rapid attack on the several Flame Demon True Lord.

Just a quarter of an hour later, the two Nascent Soul Early Stage Flame Demon True Lord were killed on the spot, leaving only the Nascent Soul Middle Stage Flame Demon and Flame Demon King struggling to hold on.

"Hahaha!"

The Heavenly Hut Sect activated the Heavenly Furnace Token, severely injuring his opponent. He laughed heartily, "It seems this battle is over!"

"That's only natural."

Upon hearing this, everyone smiled. Once they had killed the Flame Demon in the Nascent Soul Middle Stage, the rest of the battle would be no problem.

"Kill! Kill! Kill!"

Seeing that the situation was dire, the Flame Demon King immediately summoned a crimson lotus, which actually unleashed a fiery red Gang Qi that blocked Chen Nianzhi and Jiang Linglong's attacks, and rushed towards the location of the Flame Demon True Lord.

"It's the Fire Source Treasure Lotus."

Chen Nianzhi's eyes widened slightly. The Fire Source Treasure Lotus was a rare and precious spiritual object of the Tier 5 Upper Grade, of which it was invaluable for both refining pills and Law Treasure.

The Fire Source Treasure Lotus in the hands of the Flame Demon King before them had been refined into a Upper-Tier Spirit Treasure, possessing unparalleled defensive power.

Especially in this Subterranean Fire Vein environment, the power of the Fire Source Treasure Lotus increased by more than 30%, making it difficult for Chen Nianzhi to break through it.

With this thought in mind, Chen Nianzhi activated the Heavenly Separation Twin Swords Unity, then shouted, "We can't let them join forces!"

"Boom--"

At the critical moment, a dazzling bolt of Yin-Yang Two-Mode Divine Thunder struck from the void, sending the Flame Demon King flying backward.

It was Lin Qianshu who propelled the Scarlet Flood Dragon Treasure Ship to defeat the Flame Demon, and at the crucial moment, Two-Mode Divine Thunder on the Treasure Ship to repel the Flame Demon King.

Taking advantage of the opportunity, Lingxu Fairy seized the chance and beheaded the Flame Demon True Lord Monarch with a single sword strike.

It's done.

Even if the Flame Demon King is strong enough, once this last Flame Demon True Lord is killed, he will not be able to withstand the siege of more than a dozen True Lord.

Just as everyone was beaming with joy, an incomparably magnificent aura suddenly erupted from the core of the ruins.

"Boom!"

A deafening roar echoed through the heavens and earth, and endless lava in the distance dispersed, revealing a Gods and Devils, ten thousand feet tall, whose entire body was flowing with crimson flames, sitting cross-legged between heaven and earth.

It sat quietly in the lava, an indescribable force field enveloping the heavens and earth, like the resounding toll of an ancient bell striking the hearts of everyone.

At the endless horizon, a dazzling golden divine light descended from the sky, enveloping his body, vaguely resembling a small, star-like sun falling down.

"This..."

Everyone stared blankly at the light continuously falling from the horizon, their hearts pounding violently.

Chen Nianzhi also felt a bit thirsty and remained silent for a long time.

In an instant, he understood the cause and effect.

The towering Flame Demon before them, standing tens of thousands of feet tall, is a Flame Demon Emperor who has guided the Earth Soul. He is currently guiding the Heaven Soul to break through to the Nascent Primordial Spirit realm.

Once this person breaks through, they will become the Lava Devil Ancestor of the Primordial Spirit Realm, becoming an unparalleled being at the pinnacle of this world.

They, including Chen Nianzhi, were just a calamity.

"I have actually become the tribulation for the Flame Demon Emperor's breakthrough to the Primordial Spirit."
