"Huh? I found a banner here! It’s the ’Myriad Poison Banner’!"

Suddenly, Yu Yunyi spoke up, indicating she had made a discovery.

"You all continue searching, I’ll take a look at this thing!"

Li Yunjing flew over swiftly, indicating to the others to continue searching.

Right in front of Li Yunjing, amidst the ruins, lay the ’Myriad Poison Banner’.

The banner was entirely emerald green, embroidered with countless poisonous creatures. The creatures that had previously attacked them were almost all depicted on it.

It seemed the poisonous creatures that appeared in the Xu residence had escaped from the ’Myriad Poison Banner’.

After all these years, this Supreme Demon Treasure had also lost control over the poisonous creatures within it.

"It turns out to be a Treasure Artifact, but unfortunately, the poisonous creatures inside are almost gone, greatly reducing its power. I wonder if it can still unleash the power of a Top Grade Spiritual Artifact."

Li Yunjing shook his head in disappointment, but he still cast his mana to conjure a large mana hand, grabbing the ’Myriad Poison Banner’ and placing it in his ’Hundred Treasures Pouch’.

He didn’t plan to store these things in his Storage Ring, to avoid any potential issues.

"Rumble!"

At this moment, the array at the tunnel exploded with immense power, almost collapsing this underworld. The entire city underwent an earthquake, countless buildings crumbled, and fissures appeared all over the ground.

Countless people were startled awake from their sleep, the entire city was shrouded in cries and screams.

No one knew what was happening, they only thought it was an earthquake, and everyone was scrambling to escape.

Shan Baiyi immediately realized something had happened, his figure darted out of the city, flying towards the direction of ’Northern Emperor Sect’!

At this moment, the dust-covered Zhao Yibai finally rushed in.

"Damn it! These little bastards are so sly!"

He cursed angrily, his face as dark as the bottom of a pot, nearly spitting blood in anger.

Unexpectedly, once again, Zhao Yibai was outsmarted by Li Yunjing and his group.

At this moment, he felt extremely aggrieved, wishing he could grind Li Yunjing and the others to dust.

However, upon realizing this was an underground city, Zhao Yibai’s thoughts changed.

In Zhao Yibai’s line of sight, he saw Li Yunjing, Yu Yunyi, Lv Ruoxi, and Fu Chao gathered together.

A large crimson seal appeared in front of them.

This blood-red four-sided seal emanated an incredibly powerful blood aura; it was a high-quality Treasure Artifact.

Zhao Yibai, feeling a bit out of control, not only didn’t panic, but excitement appeared on his face.

Ever since joining the Demon Dao, he had always wanted to craft a Demon Artifact for protection.

Now that a ready-made treasure was before him, how could Zhao Yibai not be delighted?

"Kekeke! Kekeke!"

Zhao Yibai laughed sinisterly, shouting, "You little bastards, initially I was furious when you ran, but now I am grateful that I didn’t kill you!"

"You four have found such a powerful Demon Treasure for me!"

"I will reward you heavily!"

"Grant you the most brutal death!"

Seeing Zhao Yibai really chasing after them, the faces of Li Yunjing and the others turned grim, though they had anticipated it!

Dealing with such a level of master was impossible using conventional means.

Even some Forbidden Artifacts couldn’t easily kill Zhao Yibai.

Facing such an enemy, Li Yunjing took out the previously obtained ’Myriad Poison Banner’, and as he poured mana into it, the giant banner suddenly opened with a loud noise.

"What! Another Demon Treasure?"

Zhao Yibai was almost stunned. He never expected a second Demon Treasure to appear here!

Could this place have been the cultivation ground of some Demon Dao giant?

Thinking of this, Zhao Yibai’s face contorted with excitement, his sinister smile making him look maniacal.

"Kill!"

Seeing the other side going a bit mad, Li Yunjing fiercely shook the ’Myriad Poison Banner’, releasing a thick green poisonous cloud.

"Hahaha! Junior, you think mere poison can harm me?"

Zhao Yibai repeatedly sneered, but he was evidently more cautious. Having been outsmarted several times by Li Yunjing’s group due to underestimating them, this time he learned his lesson, conjuring a thick ice shield three zhang (approx. 9.9 meters) around him.

With his defense fully activated, even a Golden Core Realm Cultivator’s direct attacks wouldn’t break it easily, let alone a weakened Treasure Artifact.

Coveting both the ’Myriad Poison Banner’ and the blood-red seal, Zhao Yibai was determined. These two treasures would give him a foothold even in Demon Dao-controlled regions.

Zhao Yibai wanted all the Demon Treasures and the lives of Li Yunjing and his group!

"Damn! A serious Golden Core Realm expert is so formidable!"

Seeing that the ’Myriad Poison Banner’ had no effect, Li Yunjing felt a bit helpless. The Spiritual Artifacts on him, whether it was the ’Jade Sea Listening Wave Sword’, the ’Celestial Thunder Emperor Seal’, or the ’Five Dragon Wheel’, had relatively small attack power and couldn’t break Zhao Yibai’s defensive Gang Qi.

"How about it? Can you use the ’Blood Demon Seal’?"

At this moment, Li Yunjing couldn’t help but urge Yu Yunyi, Lv Ruoxi, and Fu Chao through a voice transmission.

"Almost there! Almost there!"

Fu Chao anxiously responded. At this moment, his face was covered in sweat, not from excessive mana consumption, but from extreme anxiety.
