Chi Yue frowned slightly. "Master, even with my strength, I can sense the danger."

"This means there is a terrifying existence within the Lingxu Mountains that can threaten me!"

"I still stand by my suggestion!"

Just as Qin Feng was about to speak, Qingluan suddenly interjected, "Master, I agree with Senior Chiyue's suggestion!"

"It's only two days anyway, there's no need to rush."

Zi Yun spoke up. "Why don't we just follow their advice?"

Leopard-like creature nodded in agreement. "Yes, Master!"

"You still have room for improvement. Why not first reach the peak of Immortal Emperor before entering the Spirit Void Mountain Range?"

"With your peak Immortal Emperor strength and that immortal artifact, entering the Spirit Void Mountain Range will be much safer than it is now."

Qin Feng looked at the group, hesitated for a moment, and then nodded in agreement.

Then, Qin Feng landed on the ground and sat down to cultivate.

Zi Yun and the others landed around Qin Feng to protect him.

Although they have a strong lineup and are unlikely to be in any danger, it's still best to be cautious.

After all, Qin Feng was cultivating, and if he were affected, he might suffer a qi deviation.

Two days passed in the blink of an eye.

Qin Feng continued his cultivation, showing no sign of stopping.

Leopard Lin is right. It's not too late for him to enter the Spirit Void Mountain Range after he reaches the peak of the Immortal Emperor realm.

After all, it's not the possibility of something happening that's scary, but the possibility of something happening in the worst-case scenario.

He is not alone; he has to consider the people around him.

Two weeks later.

Qin Feng's cultivation level has finally reached the peak of Immortal Emperor, and his aura is far stronger than that of Zi Yun, Chi Yue, and Bao Lin.

Now, if he were to face a half-step Heavenly Emperor Realm expert, he wouldn't even need the Immortal Execution Sword to kill them.

Zi Yun and the others were extremely shocked. In just over half a month, Qin Feng had actually advanced from the mid-stage of the Immortal Emperor realm to the peak.

They were absolutely stunned.

When did it become so easy for Immortal Emperors to advance their cultivation levels?

Qin Feng himself was also very shocked; he had thought it would take at least two or three months.

I never imagined that it would be done in just over half a month.

He also believes that his improvement speed is too incredible, and there are no hidden dangers at all.

Only then did Qin Feng finally remember the Qiankun Jade Pendant hidden somewhere inside his body.

To this day, he still doesn't know what kind of heaven-defying treasure the Qiankun Jade Pendant is.

He was able to embark on the path of cultivation because of the Qiankun Jade Pendant; without it, he would have died long ago.

He inexplicably arrived in the Xuan Tian Immortal Realm, seemingly due to the Qiankun Jade Pendant.

When he first broke through to the Immortal Emperor realm, the Qiankun Jade Pendant appeared, inexplicably causing his realm to drop to the early stage of Immortal King.

His cultivation speed has always been extraordinary, which is probably related to the Qiankun Jade Pendant.

The Qiankun Jade Pendant was a terrifying mystery to him.

Whether it's good or bad that it's been hidden inside him all this time is unknown.

Qin Feng composed himself, stood up, looked at the Lingxu Mountain Range ahead, and said with a glint in his eyes, "I hope this trip will be fruitful?"

Zi Yun smiled and said, "There will definitely be something to gain!"

Qin Feng simply smiled and said nothing, then flashed off towards the Lingxu Mountain Range.

Zi Yun and the others immediately followed.

As soon as Qin Feng entered the Lingxu Mountain Range, he felt a surge of pure spiritual energy rushing towards him.

Just one breath was enough to refresh one's mind and body, and the energy cultivation techniques started to operate on their own.

But after a while, Qin Feng sensed that something was not right.

"Something's wrong! There's something strange about this spiritual energy!"

Zi Yun and the others also noticed something strange about the spiritual energy and nodded slightly.

"Something definitely isn't right!"

"This spiritual energy is purer than that of other places, and it seems to contain a peculiar kind of energy!"

At this moment, Chi Yue's eyes flickered as she said, "This...this seems very much like the legendary celestial energy!"

"It is said that absorbing the celestial energy can transform one's internal spiritual power into celestial power, making one a true immortal who can enjoy eternal life and live as long as heaven and earth."

Qin Feng looked bewildered. He seemed to have heard something similar before, but he couldn't remember who said it.

However, he had never heard of the concept of celestial energy.

Just then, Xiao Xian's voice suddenly rang in Qin Feng's mind. "This is not immortal energy, but an illusion you have created!"

What?

Qin Feng was shocked. Was he hallucinating? Was it real?

If it's true, why didn't any of them notice?

Qin Feng scanned the area with a flickering gaze, but found nothing unusual.

He pondered for a moment, then asked Xiao Xian telepathically, "Was what Chi Yue said just now true?"

"Can the celestial energy truly transform the spiritual power within the body into celestial power?"

Xiao Xian quickly replied, "Most of them are true!"

"But the celestial aura doesn't transform spiritual power into celestial power; it's celestial essence!"

"Unfortunately, the Xuan Tian Immortal Realm is only a mid-level realm, and it's impossible for it to contain immortal spiritual energy!"

"As far as I remember, it seems that only the top-level realms contain immortal spiritual energy, and the amount is extremely small!"

"Don't think about that. Even if you find the immortal energy, you won't be able to use it for the time being!"

"We'd better find a way to break the illusion quickly, or you'll all get lost in it sooner or later."

Qin Feng took a deep breath, then looked at Zi Yun and the others and said, "There's an illusion here!"

"What we see and feel now is all fake!"

Zi Yun was stunned for a moment, then exclaimed in surprise, "No way?"

"With our strength, how could we have entered an illusion without even realizing it?"

Chi Yue and Bao Lin exchanged a glance, their brows furrowing.

In fact, they had already had some doubts, and now that Qin Feng said this, they were even more certain of their suspicions.

"Master is probably right," said Chi Yue. "This place is indeed very likely an illusion!"

"However, we've only just come in and haven't gone deep yet, so we haven't been separated!"

Upon hearing this, Zi Yun and the others immediately released their divine senses to investigate; they simply refused to believe it.

If it really were an illusion, would they not have noticed it at all?

After a while, Zi Yun and the others withdrew their divine senses one after another, their eyebrows slightly furrowed.

How could they not have noticed anything suspicious at all?

Zi Yun questioned, "Could it be that you're mistaken?"

"If it really is an illusion, how could we not have noticed it?"

Qin Feng glanced at Zi Yun. "It's normal that you can't find out. Actually, it wasn't me who found out; it was the spirit of the Zhuxian Sword that told me."

Upon hearing Qin Feng's words, Zi Yun and the others no longer had any doubts and believed him without a doubt.

The Zhuxian Sword is a top-grade immortal artifact, and Xiaoxian, as the spirit of the artifact, is also very powerful and has far more experience than them, so it is unlikely that she would make a mistake.

Zi Yun asked, "Then what do we do now?"

"If we can't even perceive the existence of the illusion, how can we break it?"

Qin Feng frowned and looked at Chi Yue and Bao Lin, asking, "Do you have a solution?"
