After the Flame Path auction ended, Lin Yan returned to the courtyard he had rented in the inner city. He entered seclusion again, repeatedly studying the Fire Control True Inheritance inside his dream, testing different refinement routes and adjusting various Gu recipes.
Each time he became more familiar with a Flame Path Gu recipe, his understanding of the Borrow Fire Gu improved a little. The progress was steady and fast, far beyond what he had achieved earlier with Human Path research for aptitude raising Gu.
This clearly showed that Flame Path was still his strongest foundation.
Seven days passed quickly. When the Treasure Hunt Auction began, Lin Yan finally came out again and joined the bidding. Among the many items, he picked out several things of value.
The most important were two White Silver Relic Gu. He bought both at the highest price of fifty thousand primeval stones each, without hesitation.
The other bidders did not compete much. Most of them were Rank 4 Gu Masters or above. They had no use for such Gu themselves, and could only pass them down to juniors. Since their resources were limited, they were not willing to spend heavily on them.
For Lin Yan, the White Silver Relic Gu was guaranteed profit. Even if he didn't use them to refine Human Path Gu Worm to improve aptitude, he could still resell them to the Family without any loss.
After all, he already held the status of a Flame Lake Gu House Family Elder. Setting a price was not difficult for him, and as long as it involved strategic resources, the Family would not refuse.
After that, during the treasure-hunting phase, Lin Yan carefully examined the unsold items one by one. In the end, he slowly shook his head. None of them showed clear value to him. He only bought a few materials suspected to be related to Human Path, then stopped.
He did not obtain what he truly wanted at this auction, but this was normal. In cultivation, most things did not go according to plan.
Lin Yan returned to his courtyard and resumed his closed-door cultivation. In his dreams, he continued deducing Gu recipes, refining his understanding step by step. At the same time, he kept pushing against the Rank 4 crystal wall, enduring the slow and frustrating progress.
More than ten days passed like this.
In his dream, Lin Yan held a newly refined Gu in his hand. It was about the size of a fist, pure white like burning fire, and under the light, it reflected faint colors, shifting and unstable.
"The Rank 3 Borrow Fire Gu… I actually succeeded?"
He felt a surge of emotion. Even with the Huang Family's accumulated knowledge and the Fire Control True Inheritance as reference, this speed was still shocking.
But when he thought about it carefully, it made sense. His attainment in Flame Path and Refinement Path had already reached a solid level, and with the time flow in the dream, he had effectively spent nearly a full year researching this.
He named this brand new Gu Fusion Fire Gu.
It perfectly realized the vision left by the Huang Family ancestors, greatly improving upon the original Borrow Fire Gu.
At Rank 4, it could draw power from Rank 4 Otherworldly Flame Gu. More importantly, unlike the old version that could only borrow from a single flame, this one had no fixed limit. It could draw from multiple flames at once, the only restriction being how much the Gu Master could control.
If Lin Yan activated Flame Demon True Body and then used Fusion Fire Gu to link the Life Spirit Fire and Mystic Yellow Earth Fire, he could hold two different Otherworldly Flame attributes at the same time, greatly increasing his combat power.
This was similar to the Otherworldly Flame Three Transformations from the Fire Control True Inheritance. Each additional flame would multiply the power of Flame Path Gu, with a limit of three layers of amplification.
But Fusion Fire Gu was different. It had no fixed limit. The more Otherworldly Flame Gu it connected, the stronger the boost became, directly surpassing the restriction of that killer move.
"Unfortunately, the idea sounds perfect, but the burden is terrifying."
Lin Yan frowned slightly. Flames were naturally violent. Forcing different flames together could easily cause instability or even explosion. Even the Otherworldly Flame Three Transformations relied on supporting methods to barely stabilize three types at once.
Lin Yan let out a quiet sigh, but his thoughts did not slow down. The Fusion Fire Gu was still outstanding. Even if the burden on his mind was heavy, he could compensate by strengthening Wisdom Path or Soul Path in the future.
At the same time, new ideas began to form. If the fused flames became too violent to control, that might not be a disadvantage. Instead of suppressing it, he could turn that instability into power and create a destructive killer move.
For a brief moment, his thoughts turned bold and dangerous. If multiple flames collapsed together at once, the explosion could reach a terrifying level. A move like that could easily wipe out everything in its range.
Lin Yan's expression grew complicated. The more he thought about it, the more he felt that this Fusion Fire Gu he had created by chance might actually be more suitable as his core Gu than Dream Derivation Gu.
