Dream Derivation Gu did not possess the ability to directly simulate Immortal-grade materials.
After thinking for a long time, Lin Yan gradually came up with a solution. He could reverse-engineer those immortal materials, dismantle their properties and effects, then transform them into various Flame Path killer moves constructed from mortal Gu worms.
By doing this, they could once again be simulated within the dream realm. The only problem was that this method consumed enormous amounts of time and effort.
Even so, Lin Yan still persevered, spending another three full months painstakingly deducing the Immortal Gu recipe until he finally pushed its completion to around sixty percent.
However, Lin Yan quickly realized that this speed was still far too slow. If he possessed Wisdom Path Gu worms to assist him, then together with the Dream Inspiration effect of Dream Derivation Gu, the speed of deduction would undoubtedly rise dramatically.
After all, Wisdom Path specialized precisely in deduction and calculation, while Dream Inspiration required almost no cost and could still produce astonishing results.
Because of this, Lin Yan once again shifted his attention toward Dream Path. He suddenly realized that the Dream Inspiration ability of Dream Derivation Gu might be able to exist independently as a separate Gu worm.
The moment this thought appeared, Lin Yan immediately began acting on it. He once again immersed himself within the dream realm, continuously searching for Dream Path materials while experimenting with new Gu worms at the same time.
Surprisingly, the entire process went far more smoothly than Lin Yan had anticipated. After more than ten days of repeated experiments, he finally succeeded in creating a new Dream Path Gu worm.
Rank 4 Dream Revelation Gu
This was a Dream Path Gu worm that possessed effects similar to Wisdom Path. By consuming mental energy, it could sink deeply into dream realms and obtain sudden flashes of inspiration, whether for deducing Gu recipes or discovering entirely new directions.
Moreover, the strength of its effect was directly related to the user's own attainment and knowledge.
Lin Yan observed the four distinct Dream Path Gu worms floating within his aperture and slowly stroked his chin.
"It seems my talent in Dream Path is far more outstanding than in other paths."
Whether it was Self Dream Gu or Dream Revelation Gu, both had been successfully created almost in a single attempt. This was completely different from the painful process he experienced while developing Creation Relic Gu and Self Will Gu, where repeated failures were common.
Part of the reason naturally came from his Refinement Path attainment already nearing Quasi-grandmaster level. However, his natural affinity toward Dream Path also clearly played a major role.
Soon, Lin Yan gradually thought of the real reason behind it all. "Could it be because I possess Otherworldly Dream Path Dao Marks…?" After transmigrating into this world, Dream Derivation Gu had also become his vital Gu from the very beginning.
His gaze swept across the four Dream Path Gu worms, but he quickly suppressed the urge to continue developing more.
Because Gu worms needed to be fed. At the current point in time, naturally existing Dream Path materials were essentially nonexistent anywhere in the world. The only method available to him was slowly extracting Dream Path materials from his own dreams through Dream Derivation Gu.
If the number of Dream Path Gu worms exceeded what Dream Derivation Gu could support, then sooner or later, those Gu worms would starve to death.
One regrettable matter was that although Lin Yan's Dream Path foundation had accumulated considerably, it still had not reached the Quasi-Master level.
Afterward, Lin Yan began using the several Dream Path Gu worms he possessed together with Dream Derivation Gu to continue deducing the Three Flavors Otherworldly Flame Immortal Gu recipe, causing the speed of progress to rise rapidly once again.
During this period, Sun Cu also managed to obtain two incomplete Rank 6 Flame Path Immortal Gu recipes for him. The first was Hell Fire Immortal Gu, an Immortal-rank Otherworldly Flame Gu with roughly fifty percent completion. The recipe clearly recorded that this Immortal Gu still existed somewhere in the world.
The second was Magma Immortal Gu, with only around thirty percent completion. However, whether the actual Immortal Gu still existed remained unknown.
Lin Yan was immediately delighted. What he truly valued was never the completion rate of the recipes themselves, but the ideas and methods behind the creation of Flame Path Immortal Gu.
Now that he possessed two genuine Flame Path Immortal Gu recipes as references, the deduction speed of Three Flavors Otherworldly Flame Immortal Gu would undoubtedly rise dramatically once again.
However, as the exchange continued, Lin Yan gradually began to frown. Only now did he realize just how terrifying the cost of deducing an Immortal Gu recipe truly was. Even with Sun Cu's support as a Gu Immortal, the expenses had already reached an astonishing level.
