These mortal Gu naturally belonged to Qin Bai Sheng, but he had already lent them to the master of the secret chamber, allowing Fang Yuan to use them freely.
He mobilized a stream of True Essence and attempted to infuse it into the Gu. The environment within the secret chamber immediately transformed.
"It seems Qin Bai Sheng really put his mind to this. It’s called a secret chamber, but it’s actually a small world, larger than a garden. What’s more, I can use these mortal Gu to freely alter the environment, creating towering mountains and flowing rivers, or vast seas and lakes, pavilions and terraces, and so on."
As Fang Yuan manipulated the Gu, the surroundings of the secret chamber constantly shifted. Sometimes he found himself in a pavilion on a lush green mountain peak, other times on a multi-story ship sailing down a surging river.
Of course, all these changes were mere illusions, not real. To truly reshape the world in an instant would require the power of an Immortal Gu, consuming a significant amount of Immortal Essence.
Fang Yuan then picked up the Gu worm at hand and focused his mind to inspect it.
This East Window Gu recorded many auction items, all rare and precious treasures. Even Fang Yuan felt dazzled by what he saw.
Some of the items had specific requirements attached. Aside from being purchasable with Immortal Essence Stones, they could also be exchanged for certain resources.
Obviously, these resources were what the owners of the items were seeking.
Fang Yuan skimmed over the earlier items, focusing his attention on the latter section.
This section listed numerous Immortal Gu, covering a wide variety of paths. Behind each Immortal Gu, exchange conditions were noted.
Unlike the previous items, Immortal Gu were unique. No matter how many Immortal Essence Stones were offered, they wouldn't be sold. This was an iron law of the market, even during the Chaotic War of the Five Regions.
Thus, to acquire an Immortal Gu, one had to offer another Immortal Gu as payment.
Fang Yuan immersed his mind and soon saw some of his own Immortal Gu listed there.
There were four major Immortal Gu: Stepping on Clouds, Roaming the World, Inviting Disaster, and Enjoying Mountains and Rivers.
The first two were both movement Immortal Gu—one belonging to the Cloud Path, the other to the Water Path. Neither aligned with Fang Yuan’s Strength Path. Although Tai Bai Yun Sheng cultivated the Cloud Path as a secondary path, as a Time Path Gu Immortal, Stepping on Clouds was not suitable for him either.
As for the Inviting Disaster Immortal Gu, it was a rank seven Gu, but its effects were disastrously bad—it was practically a tool for self-destruction in the Luck Path. Although Fang Yuan had conceived of some uses for it, exchanging it for other Immortal Gu would be far more worthwhile.
The last one, the Enjoying Mountains and Rivers Immortal Gu, could produce large amounts of Joyful Intent. However, Fang Yuan was already preparing to mass-refine Evil Thought Gu. This would render the Joyful Intent obsolete. He might as well take it out and see what Immortal Gu he could get for it. If he couldn't trade it away, he could always take it back.
Naturally, the requirements for the Immortal Gu Fang Yuan wished to obtain were written behind these four Gu.
It was worth mentioning that Fang Yuan had put these four Immortal Gu on the market through Li Shan the Fairy, effectively distancing himself from them.
Although selling Gu like Inviting Disaster was a bit of a hot potato and could bring trouble, exchanging them for usable Immortal Gu was a net benefit.
If he missed this golden opportunity, he would have to wait for the Chaotic War of the Five Regions, which was several centuries away.
Fang Yuan was cautious by nature, but he knew when to act decisively. When it was time to take a risk, he would never shrink back.
"Besides these four Immortal Gu, I still have the Spring Autumn Cicada, Pure Soul, Connect Luck, Woman’s Heart, and I suppose Wisdom Gu counts as well." Fang Yuan counted. He needed all of these remaining five Immortal Gu, so he wouldn’t sell them. He would even try his best to avoid any chance of them being exposed.
As for the Spring Autumn Cicada, those who used it knew its value. Although it had a chance of failure, Fang Yuan had reaped many benefits and gained valuable experience from it. He was already dependent on it. Even with Wisdom Gu in the Fox Immortal Blessed Land, the Spring Autumn Cicada remained his greatest trump card.
Fang Yuan had already decided to keep the Spring Autumn Cicada as his lifebound Gu in his first aperture. If the opportunity arose in the future, he would choose the Time Path to ascend to immortality.
The Pure Soul Immortal Gu was the core of the Immortal Killer Move 'Myriads Self'. Although it was currently hungry and couldn't be used, he wouldn't sell it.
Connect Luck was an auxiliary Immortal Gu that compensated for the Spring Autumn Cicada's drawbacks. Having personally experienced the power of the Luck Path, Fang Yuan would never let go of this Gu either.
As for Wisdom Gu, he didn't even think about it. Taking it out would stir up a storm and bring deadly disaster.
As for the Woman's Heart Immortal Gu, it was originally something Fang Yuan had planned to abandon as well. However, through a twist of fate, he comprehended the Venomous Breath killer move. Now, the Woman's Heart Immortal Gu was implanted inside his right chest.
It looked like a heart, beating faintly, but it was rather small, only the size of a baby's fist. Its entire body was purple-black, wreathed in poisonous gas. It was now connected to Fang Yuan's blood vessels. With every breath he took and the slow circulation of his zombie blood, it constantly seeped out poisonous gas that participated in his internal cycles.
From this, one could clearly see the shadow of the Wisdom Path killer move 'Harboring Evil Intentions'.
However, the auxiliary mortal Gu surrounding the Woman's Heart were more akin to a reverse-refinement Gu formation. Through reverse refinement, it extracted the power of the Woman's Heart.
This was due to the special property of the Woman's Heart Immortal Gu—Combined Nurturing and Refining.
This Gu required the hearts of women to be fed to it. Once it was full, the more hearts it had consumed, the stronger its power. Now, Fang Yuan had reversed this process to extract its power.
Humans were the spirit of all living things.
Although the Woman's Heart was a consumable Immortal Gu and would normally be used up completely in a single use, by devising a method and pairing it with Gu worms, one could continuously extract its power and reuse it.
