From her research, she discovered that this world does indeed have Immortal Qi, but a downgraded version of the real one. However, even with this off-brand version, it still granted the cultivators of this world a very long lifespan.

After making this discovery, Wu Hong became more interested in this world. She wanted to find the source of this downgrade Immortal Qi; this secret alone might be worth more than the reason she came here.

With hesitation, she left the compound of the Flying Sword Sect to a desolate place and immediately simulated the aura of an Earth Immortal. Then, just like what happened to her in the mortal world, Tribulation Thunder descended from the sky, then she ascended to the Immortal World.

The first thing that Wu Hong noticed after arriving was the fact that her strength was no longer limited; she no longer felt like she was in a suffocating cage.

After taking a deep and long breath, she ignored the people around her that wanted to either solicit her or ask her what sect she was from. She immediately disappeared from their sight.

After a few teleportations, she appeared in front of a cave that was surrounded by formations. With a flick of her finger, the formation was broken.

"Who?!" roared a voice from inside.

Wu Hong looked at the old man who appeared in front of her. With just a look from her, the old man found himself frozen and unable to move. A look of horror appeared in his eyes.

After pointing her finger at his forehead, Wu Hong quickly searched the old man's soul. However, she was still gentle and did not leave any problems for him.

She quickly learned that he was a Heavenly Immortal, which was this world's equivalent to Supreme Realm. After the Earth Immortal is Mystic Immortal, followed by Heavenly Immortal.

Finally, the Heavenly Immortals can compete for the Heaven Will and reach the realm of Immortal Emperor.

"My guess was correct," muttered Wu Hong with a voice only she could hear. "This world does not practice law, but focuses on accumulating energy to sublimate it."

Wu Hong knew of cultivation systems that only focus on only accumulating energy. These kinds of systems usually sacrifice one thing for another; they are usually following the path of extreme.

For example, the Immortal System of this world sacrifice strength and battle powers for a long lifespan. The average Heaven Immortal can live for more than 200 million years, which is more than 200 times the average lifespan of a Supreme Realm True Monarchs.

However, from what Wu Hong observed, an average Void Shaterring Realm cultivator from her world has the same strength as a Heavenly Immortal.

On top of that, there is another flaw in the cultivation system that focused on energy accumulation: they usually create very weak Great Emperors.

Controlling the law is a process of slowly training to control the Great Dao. However, since energy-based systems do not have this training wheel as support, once they absorb the Heaven Will, it becomes harder for them to control the Great Dao Source of a Great Emperor.

Wu Hong along with many Great Emperors despise Energy-Base System. The reason is that these systems are not training cultivators to become Great Emperors, but to become Immortal Venerables.

The highest level of energy that mortals underneath the Great Emperor Realm can bear is Immortal Qi. So, the ultimate end of the Energy-Base System is to turn whatever energy that they cultivate to Immortal Qi and achieve immortality.

After getting the information she needed from that old man, Wu Hong pondered whether she should search the source of diluted Immortal Qi in this world first, or accomplish her original goals first.

After pondering for a brief moment, she decided to accomplish her goals first as she might have to confront this world's Heavenly Dao when doing the second one.

So, based on the information she received from the old man, she headed to her destination: the Ancient Magus Region.

The Immortal World is divided into countless regions ruled by powerful sects with Emperor Lineages. However, the Ancient Magus Region is one of the few ownerless regions of this world because it was the site of an ancient battlefield where countless powerful beings fought and died.

As a result of this, many secret realms and inheritance is left there. The many different Emperor Lineages did not want other factions to occupy such a place full of resources, so an accord was reached that no one was allowed to occupy the region.

After arriving at her destination, Wu Hong could see many cultivators flying in the air, heading to different places trying to find a fortunate encounter. They usually used a sword, a gourd, or a crane. These were the most flying tools.

After a quick investigation, she quickly realized that the cultivators of this world relied too heavily on their magic weapons; this should be a way for them to make up for their lack of combat powers.

Nevertheless, she had to agree that compare to the origin artifacts of her homeworld, the magic weapons of this world were indeed way more powerful.

Wu Hong used her memory to search a specific Secret Realm. After entering it, she became very cautious. Instead of using her absolute strength to rush straight to the core, she passed the trials one by one.

While standing in front of a formation, she casually punched it, then the number "500 million Jin" appeared.

"I understand now how Wang Wei was the only one who managed to pass this trial in this world. With him re-cultivating the [Ancient Desolate Body Scripture], it should be easy for him to reach the minimum requirement of this trial."

After muttering these words, Wu Hong waited for a few seconds before she was teleported to a simple room with only a small mat in the middle. On the mat sat an illusory old man dressed in a black robe. The old man had one distinguishable feature about him: his skin was bright red.

With just a glance, Wu Hong could tell that this was just a recorded message.

"My name is Dao Monarch Qianwu. If you're reading this message, it means that I have already fallen. Although I had expected this outcome, it still saddens me that this finally arrived.

"Honestly speaking, I have no real request. As a [Insurgence Heaven Chosens] my life was fantastic and I have no regret. My only wish is that you do justice to my inheritance."

After the old man's figure disappeared, two books appeared on the mat. Wu Hong sighed as a look of respect appeared in her eyes.

In the Endless Void, the final destination of all cultivation systems can be summarized into three paths: the Emperor Path, the Dao Path, and the Immortal Pathwhich corresponded with the three realms of Great Emperor, Dao Ancestor, and Immortal Venerable.

The Emperor Path is the superior one, and the difference in strength between the other two is quite vast. An ordinary Great Emperor can easily slaughter hundreds of Dao Ancestors and ten thousand Immortal Venerables; the gap is simply immeasurable.

However, nothing is set in stone. Between Heaven and Earth, there are a few geniuses who decided that they will not succumb to their fate; they won't bow down their heads.

Through secret techniques, weird cultivation techniques, or powerful weapons, these geniuses managed to decrease the gap in strength between them and Great Emperors: they are called [Insurgence Heaven Chosen].

There is only one way to become one of them: having the strength to defeat a Great Emperor at the same level.

Wu Hong has actually read about Dao Monarch Qianwu as he was one of the most powerful Insurgence Heaven Chosen of his time.

When he was in the Dao Ancestor Realm, he could defeat Great Emperors. When he was in the Dao Ruler Realm, he could defeat Empyreans. And even when he entered the Dao Monarch Realm, he could defeat Paragons.

During his era, the power of the Insurgence Heaven Chosens reached its peak. Unfortunately, his overwhelming influence was detrimental to the power of Paragons, so his existence could no longer be tolerated.

In his last battle, he fought against 4 Paragons for a month before he was executed, and he still managed to heavily injure one of them.

This man should have been a legend in the world; a hero whose name spread through the ages. Regrettably, the people who orchestrated his death did not want this to happen, so they forcibly erased his name from history.

It was only because of Wu Hong's high status and strength that he learned about it.

With a wave of her hand, the two booklets floated to her. One of them explained the life of Dao Monarch Qianwu. Unfortunately, it was only his early life. Wu Hong used her Divine Sense to write the rest of the story based on what she knew. Then, she placed a seal on it that require the right occasion to be removed.

As for the second book, it had the title [Fiendgod Body 12 Revolutions].

After flipping through it quickly, she sighed: "It's a shame that only the first 9 Revolutions are in here."
