Fang Yuan still needed to solve the problem of feeding these insects.
"Star Fireflies feed on Star Dust Grass. I have a large number of Star Dust Grass seeds here that I can sell to you." The Space-Time Star Lord was the first to transmit his divine thought.
"I need the seeds, but I also want your cultivation experience. Let's first look at the strength of the treasure light." Fang Yuan, through Little Fox Spirit, transmitted his divine thought to Space-Time Star Lord, Fairy Yao Guang, and Di Yuan.
Soon, three documents entered Treasure Yellow Heaven, each emitting a treasure light.
This time, it wasn't Space-Time Star Lord, but Fairy Yao Guang's document whose treasure light was the strongest, fully six feet high.
"I love growing grass the most. The Star Fireflies are just a small group I deliberately moved here for the reproduction of the Star Dust Grass. If you choose my document, you definitely won't lose out." Fairy Yao Guang transmitted her divine thought.
Fang Yuan pondered.
He had actually forgotten about it; after all, in his previous life he had never used Star Gate Gu, nor had he any need for it.
Now, after successive reminders from Lang Ya Land Spirit, Omniscience Gu, Space-Time Star Lord, and the others, his memories regarding this matter were becoming clearer and clearer.
In his memories, once the Star Gate Gu appeared, everything related to the Star Firefly Gu became a top secret that no one would ever trade.
"Lang Ya Land Spirit obtained the recipe for Star Gate Gu. He might refine it and sell it in Treasure Yellow Heaven. Once Star Gate Gu is placed in Treasure Yellow Heaven, obtaining these secrets will be extremely difficult."
Thinking of this, Fang Yuan made his decision and had Little Fox Spirit transmit his divine thought: "I'll take all three of these. I'll pay with Immortal Essence Stones."
The purchasing power of an Immortal Essence Stone was quite formidable.
One Immortal Essence Stone was split into three portions, buying all three documents, and there was still a quarter of the original stone left over.
Fang Yuan opened the three documents. They each contained many points written on them:
"Star Dust Grass can only be planted in the sky, growing on clouds. Therefore, premium cloud soil is often chosen for cultivation..."
"Star Dust Grass prefers shade and dislikes sunlight. Excessive sunlight will dry it out. However, it cannot be completely deprived of light. The required amount is approximately..."
"If Star Dust Grass has Star Fireflies living on it, they help spread the seeds, allowing it to spread faster and grow better..."
Of the three documents, Di Yuan's was the most concise and reliable. Space-Time Star Lord's had unique innovations, while Fairy Yao Guang's was the most detailed and comprehensive. Fang Yuan learned from their strengths, cross-referenced and combined them, quickly memorizing everything and instantly becoming an expert in cultivating Star Dust Grass.
He chuckled inwardly. "With this, I can become the biggest seller of Star Firefly Gu in the future. Once Star Gate Gu becomes prevalent, I'm sure to make a fortune!"
"Time to buy the wine." Fang Yuan was still fixated on the ultimate fine wines.
He had already collected three types of ultimate fine wine, needing only the last one.
Naturally, there were also ultimate fine wines for sale in Treasure Yellow Heaven. They were mainly used by Gu Immortals for refining Gu and only secondarily as a fine beverage to enjoy life.
But just as Fang Yuan was about to purchase the ultimate fine wine, the entire Treasure Yellow Heaven suddenly erupted. Countless divine thoughts surged wildly.
"An Immortal Gu! Someone is selling an Immortal Gu!" Little Fox Spirit cried out in shock.
The scene on the mirror flickered, revealing the image of an Immortal Gu.
"Mind Travel Gu!" Fang Yuan's pupils constricted slightly.
This Immortal Gu for sale was precisely the Mind Travel Gu he needed. Someone had beaten him to it and seized the ownership of the Mind Travel Gu.
"Hmph. In the end, I was still a step too late." Fang Yuan was stunned for a moment, then let out a light laugh.
To refine the Second Aperture Gu, he absolutely needed the Mind Travel Gu. But in the Three Kings Blessed Land, circumstances had forced his hand. He had refined the Mind Travel Gu into Fixed Immortal Travel.
According to the Legend of Ren Zu, one had to drink the four ultimate fine wines to obtain the Mind Travel Gu. Fang Yuan had been collecting the wines all this time, yet now someone had outdone him.
"Without the Mind Travel Gu, the Second Aperture Gu is just one step short of completion and cannot be finished. Fortunately, there are still decades of time."
"On the other hand, it's still because my Gu refining on Three Forks Mountain was too high-profile, making it widely known in the Southern Border. Haha, so it's not strange that someone beat me to it."
Fang Yuan shrugged. He had actually anticipated this matter long ago.
Many Gu Masters had witnessed the process of him using the Mind Travel Gu to refine Fixed Immortal Travel. This matter had definitely caused a huge commotion. The Gu Immortals of the Southern Border weren't fools, how could they not take action?
It was just that Fang Yuan had been holding onto hope regarding the internal conflicts and mutual constraints among the Gu Immortals, so he had been persistently collecting.
In one's life, there are always things, even if the hope isn't great, if you struggle and strive for them, you won't regret it. If you don't strive at all, you won't even have a sliver of hope.
"Things in the world are often unsatisfactory. I've long since gotten used to it. However, since the other party has put this Mind Travel Gu up for sale, it means they have the intention to trade. Let's take a look first."
Fang Yuan remained calm and composed. He did not fret over gains and losses, and his state of mind stayed peaceful.
Even though Treasure Yellow Heaven was the largest trading market for Gu Immortals, transactions of Immortal Gu were still extremely rare. In history, the number of trades of Immortal Gu could be counted on one hand, and most of them involved Gu Immortals reaching an agreement first before using Treasure Yellow Heaven as an intermediary to verify the authenticity with treasure light, ensuring the safety of the trade.
The vast majority of these trades were Immortal Gu for Immortal Gu. However, the Gu Immortal selling the Mind Travel Gu, Old Man Yan Shi, made an unusual request.
"I want to exchange this Mind Travel Gu for the recipe of the Second Aperture Gu."
