Mortal: I became invincible after becoming sworn brothers with Han Li.

After seeing the scene inside the third level, Li Yunfan did not rush forward. Instead, he slowly released his divine sense and carefully scanned the third level again. After confirming that there were no formations or traps, he slowly walked towards the stone pillar.

To his relief, nothing happened until he reached the low stone pillar.

Looking at the ice ball in front of him, which was constantly emitting wisps of white, cold air, Li Yunfan couldn't help but frown.

Although the ice hockey puck was constantly emitting cold air, he did not feel the slightest bit of cold on it, which seemed very strange.

After a quick thought, he suddenly directed the spiritual energy within his body to flow into his eyes.

A glint of light flashed in his eyes, faintly carrying a blue glow; he had actually unleashed the Bright and Clear Spirit Eyes!

With the aid of his spiritual vision, Li Yunfan indeed discovered a slight anomaly on the ice ball. After a moment's thought, he turned his head and began to examine other areas on the third floor.

This time, he saw three places with abnormal spiritual energy fluctuations through his spiritual eyes. Then, he raised his palm, and spiritual energy gathered into a red ball of light in his palm.

With a gentle toss, the red ball of light flew to the top of his head. Then, he clenched his fist, and the red ball of light exploded into three streams of spiritual energy with a "bang," which shot towards three different locations on the third floor!

As the abnormal fluctuations at those three locations disappeared, the icy ball of cold energy in front of Li Yunfan also vanished instantly, leaving only a round, dark blue bead the size of a longan, which fell onto the stone pillar with a "clang".

"It's an illusion..." Li Yunfan muttered to himself, looking at the top of the stone pillar.

It turned out that the so-called ice ball of cold air was just an illusion set up here, which was why Li Yunfan could not feel the slightest bit of cold.

Although the illusion was simple, even his divine sense could not see through it. If it weren't for his own profound mastery of formations and the assistance of the Mingqing Spiritual Eye, he probably wouldn't have been able to discover the clues.

"Could it be that this so-called ancestral chill and lingering divine will is just a lie?" Li Yunfan wondered to himself.

The ease with which he succeeded gave him a sense of unreality. He wondered if the Core Formation female demon was lying, or if this was a lie left behind by her ancestor...

After pondering for a while, he sighed softly and raised his hand to take the dark blue bead into his hand.

The bead was completely cold and extremely hard, with no trace of spiritual energy emanating from it, as if it were an inanimate object.

Li Yunfan frowned slightly as he looked at the bead in his hand. After examining it carefully for a while, a thought struck him, and his divine sense immediately drilled into the bead.

To his surprise, the moment his divine sense touched the bead, it inexplicably slipped away, as if the surface of the bead were extremely smooth.

This discovery surprised Li Yunfan, and after trying it a few more times, the result was still the same.

So he withdrew his divine sense and instead used his spiritual power to inject it, but the bead seemed to have no spiritual connection at all, and the spiritual power could not enter at all!

Li Yunfan was truly shocked. He knew that even ordinary trees, rocks, and other inanimate objects could be penetrated by divine sense and spiritual power without hindrance.

However, it had no effect on the dark blue bead, which meant that it was definitely not a simple thing, and might even be an extremely rare treasure!

A glint flashed in his eyes, and he put it into his storage bag before turning and walking toward the smooth stairs.

Upon seeing the female Han Chi guarding the entrance to the second-floor staircase, Li Yunfan immediately became extremely alert, and his spiritual energy began to circulate rapidly within his body.

He glanced at the female Han Chi Bing'er standing beside him and mentally prepared for both possibilities.

If he detects any unusual behavior from the Core Formation Cold Demon, he will immediately take the female Cold Demon, Bing'er, hostage. If he fails to take her hostage, he will instantly rush back to the third floor!

Upon seeing Li Yunfan's figure, the Core Formation female demon Han Chi's eyes revealed surprise and anticipation, and she immediately asked.

"Did it work?"

Li Yunfan did not answer immediately upon hearing this. Instead, he waited until he walked down the steps and stood near the female Han Chi Bing'er before finally nodding and speaking.

"I did obtain something on the third floor, but I don't know if it's the treasure you mentioned."

"Quickly, show it to me!" The female demon said excitedly, her face lighting up with delight.

Seeing this, Li Yunfan flipped his palm over, revealing the dark blue bead, and slightly extended his hand to let the other party examine it.

Upon seeing such an inconspicuous object, the female demon was slightly taken aback, and then a look of doubt appeared on her face, clearly indicating that she was not very familiar with this object either.

"Senior, is this the treasure you mentioned?" Li Yunfan asked slowly, his eyes narrowing slightly.

The Core Formation female demon, Han Chi, did not answer. After pondering for a moment, she suddenly released a burst of spiritual energy that enveloped the round bead.

Li Yunfan's expression changed, and just as he was about to take action, the orb that had been carried into the air by spiritual energy emitted a dazzling blue light, causing all three of them to involuntarily close their eyes.

When Li Yunfan opened his eyes again, he found that the round bead was actually embedded in the forehead of the Core Formation female demon Han Chi!

The Core Formation female demon, Han Chi, seemed to be frozen in place, her eyes tightly closed and motionless.

This sudden turn of events left Li Yunfan stunned, unsure of what had happened to the other person.

"Could it be that bead?" Li Yunfan couldn't help but wonder after glancing at the round bead on the other person's forehead.

Thoughts flashed through Li Yunfan's mind, and he moved again toward the female Han Chi Bing'er beside him.

Regardless of why the other party was standing still, he felt safer taking the female Han Chi Bing'er hostage first.

Just as he raised his hand to grab the arm of the female demon Bing'er, she finally opened her eyes again, and a very complicated expression appeared on her face.

After a moment, he let out a long sigh and looked at Li Yunfan, saying, "This is indeed a treasure of my clan, but it's not what I expected..."

Li Yunfan slightly shifted his body to the side, gently blocking the arm that was holding the female demon Bing'er, before speaking with a hint of wariness.

"Since the treasure is indeed genuine, please fulfill your promise, senior!"

Upon hearing this, a strange look flashed in the eyes of the Core Formation female demon Han Chi, and she said softly.

"You don't need to be so careful. Since I said I would send you back to the ground, I won't break my promise."

He paused for a moment after speaking, and then continued.

"You don't need to threaten me with Bing'er. Not only will I not harm you, I'll also give you a benefit. And this benefit is related to Bing'er. If you accidentally hurt her, you'll miss a golden opportunity to advance to the Nascent Soul stage!"

Li Yunfan's expression changed, shocked that the other party had guessed his plan, and also shocked by the benefits of advancing to the Nascent Soul stage that the other party mentioned!

Moreover, judging from what the other party said, it seems to be related to the female demon Bing'er beside him.
