Chapter 1645: Old Friends Reunite

After saying these words, Xu Yang had already made up his mind to lead his demon beast army to a decisive battle against these powerful ancient demon souls.

"Now is the time. Nothing can stop us. Advance!"

As his voice fell, Xu Yang once again summoned both the Sky Atlas Divine Artifact and the Jade Bone Divine Sword. He held them crisscrossing in front of his chest, and two brilliant beams of eternal sword light converged, forming an incredibly massive sword outline. A terrifying surge of sword energy instantly cleared all living beings within a thousand meters of Xu Yang's body.

Two immense sword beams slashed horizontally, striking hard against the surface of the hundred-foot-high black city wall.

Thus, in front of all the warriors from both armies, Xu Yang, by his own power, cleaved the colossal wall into nothingness. As his two vast sword beams were unleashed, their terrifying power completely erupted.

The towering wall, like a formidable fortress, crumbled with a roar. The only barrier that had spanned the battlefield collapsed completely before Xu Yang's might.

With the colossal wall's obstruction gone, all the warriors under Xu Yang seemed to have completely unleashed themselves.

They let out furious roars, pressing continuously into the city's depths. The demon beast warriors trampled over the shattered remnants of the city wall, their earth-shattering battle cries echoing endlessly.

All the hundreds of thousands of Kunlun generals who had not managed to retreat fell under the weapons of the demon beast clansmen.

Xiaohua, Ling Yao, and the Four Great Demon Saints, the top powerhouses of Xu Yang's core team, all showed immense excitement.

"We've finally breached North Sovereign City; it's time for us to show what we can do."

With that, the most powerful cultivators among them soared into the air, completely unleashed. No longer needing to command the army behind them in the siege, they were now free to fight, charging towards the deepest parts of North Sovereign City where ancient evil souls, constantly coalescing from black demonic energy, resided.

They intended to directly engage with these most formidable forbidden powers of North Sovereign City.

As the true linchpin for everyone, Xu Yang's immediate task was not to hastily eliminate those powerful evil souls, but to quickly locate the source arrays releasing the black demonic energy, and the seal connecting this Fifth Forbidden Zone to the Peak of Kunlun. These two were the real secrets Xu Yang sought.

"Something's not right. These black demonic energies seem unusual; I even detect a familiar aura within them."

Just as Xu Yang was about to infiltrate the deepest part of North Sovereign City alone to find answers, Goddess Yanxia, the inheritor of the Eighteen Ancient Gods' power, suddenly spoke, sharing her thoughts with Xu Yang through a soul-to-soul communication.

"Oh, you mean these black demonic energies seem to belong to one of the Eighteen Ancient Gods? How is that possible? The Eighteen Ancient Gods had no reason to be involved with the Kunlun Divine Dynasty back then."

Xu Yang immediately questioned this, but Goddess Yanxia's reply was:

"Theoretically, that possibility is indeed very low. However, in ancient times, the Eighteen Ancient Gods, though sharing a unified title, largely acted independently. Unless there was a major event like the Kunlun lineage facing an external invasion, the Ancient Gods almost never fully assembled to collectively resist powerful external foes."

Hearing Goddess Yanxia's explanation, Xu Yang tried to shift his perspective and grudgingly gave her judgment a bit more credence.

"So, according to you, let's first find the so-called source of this aura and see if the entity creating these demonic energies is indeed Motian, one of the totems of the Eighteen Ancient Gods you mentioned!"

The name was entirely unfamiliar to Xu Yang, but Goddess Yanxia knew it quite well.

Led by her, Xu Yang and Goddess Yanxia soon arrived at the southwestern edge of North Sovereign City.

The area was surrounded by mountains and lush trees, appearing quite pleasant, but the sky above was completely covered by an endless expanse of black demonic energy.

Goddess Yanxia's expression grew a little solemn. This was the first time she had voluntarily acted as a guide for Xu Yang.

"If I'm not mistaken, the source of these demonic energies lies deep within this mountain range."

Xu Yang raised an eyebrow and glanced at her.

"You mean the seal of the array releasing these demonic energies is hidden beneath these green canopies?"

Goddess Yanxia nodded. "Exactly. Demonic energy, when compared to the essence of spiritual energy from heaven and earth, exhibits a stark difference. If it weren't sealed in an area rich with life force, it would surely affect the entire cultivation environment of North Sovereign City. The predecessors from hundreds of thousands of years ago were all highly experienced cultivators. How could they overlook such a technical issue? I'm confident my judgment is correct."

Xu Yang decided to test it out, not having much faith in Goddess Yanxia's judgment. But when he fiercely swung the sword light in his hand, a massive wave of eternal sword energy instantly carved a deep scar into the very center of the thousand-mile-wide greenery below. Immediately afterwards, the powerful source of black demonic energy at the bottom of this mark quickly revealed itself.

Large swathes of black aura rapidly surged towards Xu Yang and Goddess Yanxia's location. Soon after, a very powerful soul fluctuation suddenly appeared within their perception range. "That's him! I would never mistake Motian's aura!" Goddess Yanxia pointed below with utmost certainty.

Indeed, as the name Motian was uttered again in North Sovereign City, Motian, who had been suppressed for an unknown number of millennia, let out a hearty laugh.

"I never thought the legacy of the Eighteen Guardian Ancient Gods would truly have a chance to reappear in the world. Sister Yanxia, it's been too many years. I wonder if you and that fellow, for whom you betrayed your sect back then, have now achieved enlightenment?"

Xu Yang truly hadn't expected that the first thing this ancient demon, sealed for hundreds of thousands of years, would say after his emergence was to inquire about Goddess Yanxia's personal feelings.

As expected, Goddess Yanxia immediately showed an impatient expression after hearing the old fellow's inquiry.

"You old rascal, after all these years, you still haven't changed your ways. It's been so long, and I truly didn't expect that you and I would share the same fate, both suppressed for countless years. But at least there's a day for old friends to reunite."

After Old Motian's soul fully recovered, he immediately transformed into a soaring dragon with a snake body and dragon head in the sky, still appearing as a totem before Xu Yang and Goddess Yanxia. After all, few ancient beings like them could retain their physical bodies, unlike Goddess Yanxia.
