The Fire Lightning True Inheritance left behind by the Fire Thunder Divine Lord in the Southern Border also had many issues. The original novel only made a passing mention of it. Several super forces had already searched the Huolei River section of the Red Dragon River, yet they found nothing at all.
It only appeared later, when the great era arrived and Fate Gu was destroyed. At that time, the inheritance finally revealed itself and was taken by Wu Yong, a Rank 8 Gu Immortal from a super force. He used Fire Thunder Divine Lord's descendant, Zhong Yi, to retrieve it. Before that moment, it had never shown any sign of existence.
For a Rank 8 Gu Immortal who had a bloodline descendant, obtaining it was simple. But for a Rank 5 Gu Master, even finding its location would be extremely difficult.
Lin Yan also had doubts. There might not even be an Immortal Gu inside this inheritance. It could be nothing more than recorded killer moves, Gu recipes, and cultivation experience.
Fire Thunder Divine Lord had been heavily injured when he set up this inheritance. He was chased across Western Desert by several super forces, and in the end, he fled to the Southern Border. With no time left, he hastily arranged the inheritance before dying.
Moreover, a Gu Immortal carried their blessed land or grotto-heaven with them. The truly valuable things would most likely be stored in the Fire Lightning Grotto-heaven, not in this external inheritance.
For Lin Yan, Immortal Gu was only the first problem. Heavenly Tribulation and Earth Calamity were even more dangerous. The calamities triggered by a Ten Extreme Physique were far stronger than normal. Even an experienced Rank 6 Gu Immortal would find them difficult to pass. If he relied on himself alone, it would almost certainly lead to failure.
In short, there were too many difficulties. Lin Yan could only deal with them one step at a time.
He stepped out of seclusion and prepared to meet Family Head Huang Ming, intending to request a transfer to the Ten Thousand Li Silk Corridor. However, before he could arrive, he heard unexpected news.
His uncle, Shan Shayuan, had been in seclusion for two years and had finally broken through to Rank 4.
"Ah… I was just about to refine Obstacle Breaking Gu."
Lin Yan scratched his head. Although Shan Shayuan had successfully advanced, his potential had clearly reached its limit. Without improving his aptitude, it would be very difficult for him to go further.
Lin Yan also had some hesitation regarding the Creation Relic Gu. Revealing such a method too early could attract unwanted attention, especially from Gu Immortals.
He let out a quiet sigh. "I'll have to wait until I become an immortal before bringing this up."
Lin Yan thought for a moment, then decided to visit his uncle. Inside the courtyard, Shan Shayuan's aura was still surging. When he saw Lin Yan, his expression froze for a moment, clearly not expecting this. He already knew about Zhang Bai's death and that Lin Yan had reached Rank 4.
"Wait… your aura?"
Shan Shayuan looked at him carefully and felt a faint pressure coming from Lin Yan's body. His eyes widened slightly as he said, "You've already reached the Rank 5 Peak stage?"
Lin Yan smiled and nodded, giving a calm reply, "The inheritance I obtained included a Rank 5 Purple Crystal Relic Gu."
At the same time, he was already thinking ahead. He needed a concealment-type Gu soon, otherwise his real strength would be exposed too easily.
Shan Shayuan looked at him for a long moment. He could tell Lin Yan had many secrets, but he chose not to ask further. Instead, he asked, "You're already at Rank 5. What are your plans next?"
Before Lin Yan could answer, Family Head Huang Ming, along with the First Elder and Second Elder Huang Feng, arrived one after another. The Family had just produced another Rank 4 expert—naturally, it drew attention.
The three stepped in—then fell silent the moment they saw Lin Yan.
They were only around Rank 5 initial or middle stage, yet Lin Yan, after a year and a half of seclusion, stepped out as Rank 5 Peak stage, firmly becoming the number one in the Family.
Huang Feng opened his mouth, wanting to speak, but in the end said nothing. At this moment, he clearly understood that he no longer deserved the title of a genius.
The First Elder calmly glanced at the two of them, his eyes giving a subtle signal.
Family Head Huang Ming immediately understood. His expression turned complicated as he said, "As expected of the genius who has suppressed our Family for a hundred generations. In seven hundred years, you may be the only one with hope to step into Immortal Ascension. If you need anything, speak freely."
Hearing this, Shan Shayuan's gaze flickered slightly. After a brief pause, he suddenly said, "Lin Yan actually has one of the Ten Extreme Physiques. I concealed this all along because I feared other families would target him."
The atmosphere instantly changed.
Everyone present was an old fox. The First Elder slowly stroked his beard and sighed, "Shayuan… you truly have hidden this from us for quite a long time."
