Just then, a sudden change occurred. The sword spirit phantoms on the two longswords suddenly opened their eyes at the same time.

At the same time, two beams of red and green light, which were too bright to look at directly, emanated from their bodies and pierced the sky in a short while, causing the tribulation lightning to be dazzling!

At the same time, two vast sword energies appeared with the light and spread outwards, instantly spreading from this place to the entire Heavenly Demon City!

Such a strange phenomenon caused all the foreign races in the entire Heavenly Demon City to stop and watch!

"He actually forged such a longsword, and this phenomenon is far beyond what ordinary divine-level magic weapons can compare to. I'm afraid that these two longswords he forged can reach the peak of the divine level, or even the immortal level!"

The City Lord's Mansion.

In the peach grove in the backyard, feeling such sword energy, even Zhu Hongjiu, who had a firm mind and was practicing the Chain Sword Technique, couldn't help but put down his long sword and stare in horror at the two pillars of light that shot into the sky!

Boom—Crack!

Before he could react, phantom images of the Spirit Race suddenly appeared on the towering pillar of light!

The Spirit Dragon Clan!

The Phoenix Clan!

The Spirit Fox Clan!

The Spirit Tiger Clan!

...

In just a few breaths, the terrifying lightning tribulation that had previously been awe-inspiring and imposing was now obscured by the constantly emerging phantoms of the Spirit Race!

"The Spirit Clan's sword-sacrifice ceremony—what a grand gesture! This person's weapon-forging skills are truly terrifying!"

Beside Zhu Hongjiu, Hu You watched this scene with a shocked expression.

It wasn't just her.

At this moment, even Zhu Hongjiu, a pseudo-saint who had lived for millions of years and possessed most of the world's magical treasures, revealed a sharp glint in his eyes and looked shocked.

Boom—Crack!

Before the two could react, another wave of tribulation lightning surged from the sky!

The tribulation lightning that appeared at this time was even more magnificent and shocking than before. It stretched for millions of miles and pressed down, engulfing the entire Heavenly Demon City. In an instant, this area was plunged into an endless sea of ​​lightning, just like a lightning domain!

What's even more terrifying is that this time the lightning wasn't pure white like before, but blood red!

Under such a devastating lightning tribulation, all the foreign cultivators in the Heavenly Demon City territory showed expressions of horror at this moment!

Many powerful emperors of inferior strength trembled uncontrollably under this tribulation of lightning. Some were even forced to prostrate on the ground by the terrifying power descending from heaven and earth, not daring to raise their heads!

Even in the City Lord's Mansion, Zhu Hongjiu and Hu You, who possessed pseudo-Saint cultivation, showed deep fear at this moment!

On the contrary, the weapon refiners of the Tianyun Clan showed unprecedented joy at this moment!

Those bloodshot eyes spoke volumes about their barely concealed excitement at that moment!

"Blood Lightning! It's actually Blood Lightning!"

"Blood lightning appears, and the celestial rank manifests! The two swords forged by the Grand Master of Weapons have actually reached the celestial rank level! This is terrifying!"

"I never imagined that the Chief Refiner would actually have reached the level of a Celestial Refiner! That's terrifying!"

"A Celestial-Rank Weapon Refiner—there's only one of them in my Heavenly Fall Clan! I never imagined I'd witness the birth of a Celestial-Rank Weapon Refiner!"

"How fortunate! How honored!"

"..."

Boom—Crack!

Boom—Crack!

Boom—Crack!

...

As soon as the lightning tribulation appeared, lightning punishment descended in an instant, bombarding the two longswords in the main weapon refining room!

However, under Su Bai's powerful suppression, these formidable lightning tribulations transformed into streams of pure lightning energy, all of which flowed into the two longswords, continuously tempering and forging them!

In just a few dozen breaths, even more powerful and fierce sword energy surged from these two longswords!

The bodies of the two sword spirits above them, dressed in red and green robes, gradually solidified during this process, and soon reached a level that was just like real people!

At the same time, as two streams of life force surged into their bodies, a unique brilliance of life shone through their empty pupils!

"Owner!"

"Owner!"

As soon as the two sword spirits gathered their consciousness, they bowed to Su Bai.

"Don't call me that. I am not your master."

Su Bai shook his head expressionlessly.

“Lord…but you created us,” said the sword spirit in red robes.

"Just remember your mission," Su Bai said calmly.

"But, Lord... after we help you kill those two, can we still return to your side?"

The sword spirit, dressed in a red robe, asked.

His face even carried a hint of human pleading.

However, Su Bai simply shook his head indifferently.

"I have companions now, but I'll find you a place to go."

"But we want to stay by the Lord's side!"

The two said in unison.

Su Bai glanced at them, his eyes devoid of any emotion.

"I don't want to say the same thing a second time."

"That's it. If you keep arguing, I don't mind ruining you all."

These words were spoken.

The two sword spirits immediately trembled and knelt down on the ground, not daring to utter another word.

Su Bai said nothing more. The violent life force continued to emanate from his palm, powerfully refining the blood-red lightning that filled the sky.

Half an hour later, he stopped what he was doing and looked at the two sword spirits.

"Now that your strength is about right, go and refine these blood lightning bolts yourselves, tempering and transforming them."

"yes!"

"yes!"
