The comet remained silent, only relentlessly unleashing heavenly tribulations.

Yi Bian Zhenjun took a deep breath, forcibly suppressing the agitation in his heart, and re-examined Song Yi.

He never expected that this newly promoted seventh-rank star lord would possess such a primordial spiritual treasure.

"A single innate restriction is indeed precious," True Monarch Yi Bian stroked his beard and pondered. "But the 'General Outline of Taiqing Purple Mansion Weapon Refining' is a secret technique of Taiqing. One restriction cannot be exchanged for it; at least... seven!"

"Two paths!" Song Yi said calmly. "Since ancient times, the Grand Master Xuandu has been spreading the Dao among the human race. There are quite a few immortals in the Three Realms who know this general outline. It is not a top secret."

"Five! That's the minimum!" said Yi Bian Zhenjun in a deep voice.

"Three items, plus a Bagua Furnace." Song Yi remained calm and unmoved. "If the True Lord does not agree, this humble god will take his leave."

Yi Bian Zhenjun stared intently at Song Yi for a long while before finally letting out a breath: "Your junior is indeed quite shrewd. Very well, deal!"

"You're so generous, True Lord." Song Yi smiled and cupped his hands in greeting.

A moment later, Yi Bian Zhenjun presented a warm and smooth jade slip.

As Song Yi scanned with his divine sense, he immediately felt countless profound methods of refining treasures flooding into his mind, including the method for refining the Golden Pill Military Talisman.

"This furnace was forged by me during the reign of Emperor Yao. It is made by melting down the red copper of Shou Mountain and the lapis lazuli of Yi wood. It contains the directions of the Eight Trigrams of the pre-heaven. It can be used to refine elixirs and also to melt down acquired spiritual treasures."

With a wave of his hand, Yi Bian Zhenjun conjured a three-legged alchemy furnace out of thin air in the center of the hall.

This Bagua furnace is about three zhang tall, with a round body and an ancient and vigorous shape. The surface is carved with flowers, birds, fish, insects, mountains and rivers, which are lifelike.

The furnace body faintly emitted a crimson light, and there seemed to be the sound of wind and thunder inside.

"Thank you, True Lord!"

Song Yi's face lit up with joy. Then, with a light tap of his fingertip, he passed on the remaining two innate restrictions.

After leaving the Lingbao Bureau, he did not linger this time. He turned around and rode on auspicious clouds with the four Thunder Department officials, heading straight for the Demon-Slaying Platform.

The Great Prison Heaven.

The Demon-Slaying Platform stands majestically, with nine thousand nine hundred and ninety-nine jade steps leading to it.

However, the once lustrous jade steps were now soaked with dark blood.

The moment Song Yi stepped onto the Demon-Slaying Platform, he truly understood what "mountains of corpses and seas of blood" meant.

Beneath their feet was not solid ground, but a turbulent sea of ​​blood, with towering waves of blood.

Countless enormous corpses floated and sank in the blood waves, and countless remnant souls let out mournful howls in the blood, their sharp and piercing voices drilling straight into the brain.

All around the edges, a dense array of weapons stood upright: knives, axes, hooks, ropes, swords, spears, halberds, long spears, giant hammers, iron chains, shackles, spiked clubs...

Each instrument of torture here is more than ten times larger than an ordinary weapon, its surface gleaming with a cold light and exuding a chilling murderous aura that inspires fear in those who behold it.

Deep within the execution platform, countless demon-slaying pillars soar into the clouds, each about ten feet thick and over a thousand feet high. Bound upon them are once-powerful demons and monsters, each with a ferocious expression and an overwhelming aura of malevolence.

"Hurry up!"

Just then, a group of heavenly soldiers arrived, escorting a large number of demons, and roughly tied them to the Demon-Subduing Pillar.

The executioners at the Demon-Slaying Platform raised their ghostly-headed swords, which gleamed with an eerie light, and slashed down fiercely at the demons on the pillars, their movements so practiced that they sent chills down one's spine.

"Snap!"

A flash of cold light, and in the blink of an eye, countless heads flew up, and bright red demon blood gushed out like a fountain, falling into the sea of ​​blood below and stirring up layers of blood waves.

The slain demons instantly revealed their true forms. Some of the great demons were enormous, reaching a height of a hundred feet, and their blood flowed out like a rushing river, merging into the sea of ​​blood below.

"Who goes there?"

A burly executioner, over ten feet tall, strode over. He had a blue face with fangs, a ferocious expression, and muscles as tough as iron, exuding a chilling aura of dominance.

He was also carrying a thick-backed broadsword, and thick, sticky blood was dripping down the blade.

"I am the God of Brooms, here to clean the Demon-Slaying Platform!" Song Yi said in a deep voice.

He knew that these executioners possessed the "Heavenly Punishment Demon-Slaying Dharma Image," which was even more powerful than his own Seventh-Rank Star Lord Dharma Image. Nourished by the evil energy of the Demon-Slaying Platform, they could unleash the strength of a True Immortal.

However, they ultimately belonged to the Heavenly Court's system of celestial officials, and were not officially appointed gods.

In the Heavenly Court, the rank of a Dharma Image Golden Body is not entirely equivalent to the level of a deity.

Just like the prison guards we encountered in the Heavenly Prison, their golden bodies were so strong that they were almost immortal, but they were only celestial officials and did not hold the position of true gods.

"So it was the Star Lord in person!"

Upon hearing this, the executioner quickly sheathed his broadsword, stepped forward, and bowed respectfully: "The malevolent aura of the Demon-Slaying Platform has reached its peak. We lowly officials only know how to kill and are not skilled in mystical arts. We beg the Star Lord to take action and cleanse it!"

Song Yi nodded slightly, then summoned the Demon-Binding Net and cast it into the air.

The net swelled with the wind, instantly growing to a size that blotted out the sky, enveloping the sea of ​​blood below.

Before long, the demon-binding net tightened, and a large number of corpses were pulled up.

Most of these corpses were not human; they included all sorts of demons, such as wolves, insects, tigers, muntjacs, foxes, elephants, lions, wild boars, and divine mastiffs. Each one was decapitated and died a gruesome death.

Song Yi made a hand seal, collecting the retrieved corpse along with its remaining soul into a huge body bag.

The body bag also came from the Lingbao Bureau. It had a very large internal space and was equipped with runes to suppress evil spirits.

During the cleaning process, Song Yi also discovered many unexpected surprises.

For nearly a century, Li Jing, the Pagoda-Bearing Heavenly King, and Nezha, the Third Prince, have frequently descended to the mortal realm, annihilating countless demonic sects and besieging numerous demon kings.

Those evil spirits, heretics, demons, and monsters numbered nearly 100,000.

Although most of the demonic magic weapons and artifacts have been confiscated by the Heavenly Court, many have still been left behind.

Because whether they are demons or immortals, they all like to refine their own acupoints into a vast space, as the saying goes, "Sumeru can be contained in a mustard seed."

These spaces are extremely difficult to detect while one is alive, but once one dies and one's life is extinguished, the space will collapse, and the treasures within will fall away.

Just as the first net was being cast, a jet-black longsword was pulled out from among the corpses.

The sword was three feet long, its cold light gleaming, exuding a chilling aura.

"This sword... it's actually forged from black jade and dark iron?"

Song Yi felt a chill run down his spine.

The "General Outline of Refining Weapons in the Purple Palace of the Supreme Purity" records many rare and precious materials in the Three Realms. Although I only scanned it with my divine sense before, I still remembered quite a few of them.

Dark Jade Nether Iron originates from Yin Mountain in the underworld and is an extremely precious material for refining weapons. If refined using the secret techniques of the Demonic Sect, it can easily break through the protective aura of Xuanmen cultivators, making it incomparably domineering.

In the time that followed, Song Yi actually found quite a few good things.

Most of them are weapons used by the demon race, and many of them are made of materials that have reached the level of immortal gold, such as dragon patterned steel, blue-green stone, earth flame black iron, red steel, and mother and child magnets.

Most of these monsters are not versed in mystical arts, nor do they understand sophisticated weapon-making techniques. They often find a good piece of ore, hastily carve some talismans on it, and then use it.

If it were to be reforged and refined, removing the dross and keeping the essence, it could be crafted into a superior immortal sword, or other powerful magical artifacts.
