Man is in the heavens, parasitic on the way

"Alright," the Yuansha Holy Ancestor, dressed in a blue palace dress, chuckled softly, her slender hand pressing down virtually. "Have you thoroughly investigated the situation in Heavenly Spirit City?"

"Reporting to Holy Ancestor, the intelligence regarding Heavenly Spirit City has been mostly gathered." A Demon Clan member, indistinguishable from the Human Clan, raised his head and respectfully presented a dark jade slip with both hands. "All the information concerning Heavenly Spirit City is within this jade slip."

Yuan Sha's divine sense surged into the jade slip. In an instant, a cold expression appeared on her beautiful face, and she murmured, "I didn't expect that in just over a thousand years, an ant from the Lower Realm would actually become a Spirit Emperor."

"I can finally have my revenge." A chilling smile appeared on Yuan Sha's exquisite face.

On another altar, Six Extremes, clad in black armor, glanced at Yuan Sha, knowing that a wisp of Yuan Sha's sub-soul had been exterminated by a person from the Lower Realm back then.

"It's quite a coincidence!" Six Extremes laughed coldly.

"Although the Human Clan is only a minor clan in the Spirit Realm, the Three Emperors are the nominal supreme rulers. To be able to become a Spirit Emperor, that kid must have some capability, so we shouldn't underestimate him too much." Yuan Sha recalled the past, and although she was angry, it was just anger, and it didn't lead to any thoughts of contempt.

Being able to cultivate to at least the mid-stage Integration realm in over a thousand years, he must have some ability.

This kind of cultivation speed is extremely rare, even non-existent, in the vast Demon Realm.

"Sister, rest assured." Six Extremes said calmly, "He's just a mere Integration cultivator, can he really overturn the heavens? As long as we make a move, Heavenly Spirit City can be easily destroyed."

Yuan Sha smiled brightly and agreed, "Sister is right, he is just an Integration cultivator after all."

Several days later, the Demon Clan army approached Heavenly Spirit City. All the strongholds within the Demon Mark range were swept away by the Demon Clan army, with only a few crucial strongholds surrounding Heavenly Spirit City remaining unconquered.

The defenses of these strongholds were so strong that the Demon Clan couldn't breach them for a time.

The army had no choice but to halt their advance!

The stronghold fortresses, like satellite cities, protected Heavenly Spirit City. Inside the fortresses, there were even large teleportation arrays connected to Heavenly Spirit City, with Human Clan cultivators constantly arriving to provide support.

On the mountain-like fortresses, countless gold and silver talismans intertwined, sending out rays of light that extended towards Heavenly Spirit City, connecting with the massive Heavenly Spirit City.

The entire vast Heavenly Spirit City was enveloped in golden radiance. Golden light intertwined, and a huge, faintly visible pattern vaguely covered Heavenly Spirit City.

Because the grand array was not fully activated, this pattern was incomplete and its specific shape could not be discerned.

Within the range of Heavenly Spirit City, golden light intertwined; outside the range of Heavenly Spirit City, demonic energy rolled, and the dark demonic energy filled the heavens and earth, spreading out.

Within the boundless demonic energy, countless figures of the Demon Clan stood tall.

They followed orders strictly and maintained strict discipline, clearly a well-disciplined army.

Within a fortress on the city wall of Heavenly Spirit City, Han Li's avatar's eyes flashed with golden light, and he clearly saw the scene within the demonic energy.

"With this quantity, I'm afraid the Demon Clan army's numbers will be astonishing, probably exceeding ten million!" Han Li's expression changed slightly.

He had originally thought Heavenly Spirit City was impregnable, but now it seemed it wasn't without the danger of being annihilated!

However, he didn't know that the largest Demon Mark passage in this demonic disaster appeared in his Heavenly Spirit Realm, and the Demon Realm army that could come through was naturally the largest.

The commander was still Six Extremes, a powerful Holy Ancestor who intended to replace the position of Bao Hua Primeval Ancestors.

Six Extremes had plotted against Bao Hua, and his power at this time was terrifyingly great, almost like a Primeval Ancestors, so the army he could mobilize was naturally terrifyingly large.

"Ten million?" Beside Han Li, a surprised voice came from a light golden mirror, "Isn't that just right?"

"Brother Teng, what do you mean by that? With a quantity of ten million or even tens of millions of Demon Clan, the number of high-level Demon Clan is very terrifying. This is not a joke!" Han Li frowned, puzzled.

"Brother Han, don't you think these Demon Clan are very suitable for refining spirit treasure?" Fang Ming's meaningful voice came, "At other times, where would Brother Han find so many high-quality materials to refine spirit treasure?"

"If tens of millions or even hundreds of millions of powerful Demon Clan are used to refine a spirit treasure, once this treasure is fully refined, it might even be comparable to a Xuan Tian Treasure!" Fang Ming's words were full of boundless temptation.

Upon hearing this, a sharp light flashed in Han Li's eyes, and his heart grew hot. He had been solely focused on how to deal with the enemy and hadn't thought in this direction at all.

Observing Han Li's moved expression, Fang Ming smiled.

He wasn't just saying it casually. This Ten Thousand Demon Banner was perfect for verifying whether some of his ideas were truly feasible!

As the saying goes, the stones of other mountains can be used to polish one's own jade. By analogy, could the method of growth for the Ten Thousand Demon Banner be used on himself or others?

"It seems it's not impossible!" Han Li murmured, looking moved.

He looked at the mirror beside him and said, "Since Brother Teng says so, you must already know what kind of spirit treasure is suitable for refining, right?"

Although his own refining skills were not bad, he still thought that the Immortal Vine Spirit's refining skills were even more powerful.

They could 'refine' Xuan Tian Treasure, but he couldn't!

"I have a treasure that is very suitable for the current situation!" From the mirror, Fang Ming's voice came with a smile.

Han Li showed joy upon hearing this and immediately cupped his fist, "Please teach me, Brother Teng!"

"Ten Thousand Demon Banner! Originally it was the Ten Thousand Spirit Banner, refined from the flesh, bones, essence, and primordial spirits of ten thousand spirits. With a slight modification, it can be made using creatures that cultivate demonic energy as materials." Although the Immortal Vine's words were calm, Han Li's heart was filled with shock.

This Immortal Vine Spirit was even more demonic than the Demonic Dao. The Ghost Luo Banner of the Yin Luo Sect, a Demonic Dao sect in the Lower Realm, only absorbed souls.

This Ten Thousand Spirit Banner, however, accepted anyone, clearly more overbearing and terrifying!

"Please help me, Brother Teng!" Han Li was silent for a moment, then nodded his head. He had no reason to refuse.

Firstly, it wasn't using Human Clan cultivators to refine the treasure anyway. Secondly, by showing such a stance, he could also stabilize people's hearts. Thirdly, he could also obtain an extremely powerful spirit treasure, which might even be used as a trump card in the future.

"Just take out the materials." From the mirror, Fang Ming's calm voice came.

Making the best use of things, he was a Human Clan before, not a Demon Clan, so he had no emotional attachment to the Demon Clan and not many psychological barriers.

With an order from Han Li, precious materials were transported from the treasury.

The light golden mirror flickered and landed on a golden altar on top of the fortress.

With a light tremor, the patterns on the golden altar glowed, and vast magic power surged into the mirror.

As the magic power entered the mirror, ripples appeared on the mirror's surface, and a golden vine extended out from the mirror.

A golden flame the size of a grain of rice floated from the vine and landed on the various precious materials piled up like a mountain.

"Boom ~"

With a burst of sound, a golden sun appeared, enveloping all the materials.

Han Li stood at the edge of the fortress platform, his expression solemn, and murmured, "Law..."

Within the flames, he sensed the fluctuations of the Law.

'Boom boom' The flames burned fiercely. In just a few breaths, the various precious materials, like a mountain, completely melted, turning into a dark spherical shape suspended in the air.

With a trembling sound, countless rice-sized runes surged from the Immortal Vine's branch, continuously entering the sphere.

As the runes entered, an astonishing scene appeared.

The huge black sphere wriggled non-stop, quickly transforming into a giant black banner several thousand zhang in size.

Below the several thousand zhang banner, there were ten smaller banners of about a thousand zhang surrounding it.

The eleven black True Demon Banners emitted waves of strange aura, making people feel awe.

The True Demon Banner had initially taken shape. The next step was to let it devour the Demon Clan and fully form!

The more Demon Clan it devoured, and the higher their quality, the greater its power would be.

Moreover, this was a magic treasure that could continuously grow, with an unfathomable upper limit!
