Ling Feng knew that Su Xingyan now considered him a bloodthirsty demon.
The previous Bai Yunyan's keen sense of smell could detect the scent of blood on him; the lingering odors from battles on the battlefield were hard to shed!
It was not surprising that Su Xingyan, a master inheritor of the Gu Poison arts, could sense the killing intent emanating from him.
Ling Feng did not offer much explanation for these misunderstandings.
It would be laughable if the Zhenbei King did not carry some scent of blood and killing intent.
"Alright, I have only one question. Elder Su, please tell me, who in Nanyun cultivates Gu using corpses!"
Su Xingyan's expression changed drastically upon hearing this.
His gaze fixed on Ling Feng was filled with an unusual intensity, as if scrutinizing him.
"Why are you asking about this?" Su Xingyan asked sternly.
"My elder brother's corpse was stolen by someone who cultivates Gu in Nanyun!"
Ling Feng stated frankly.
"So that's how it is!"
Su Xingyan's expression softened slightly, showing a hint of hesitation.
But he was a man of his word; having promised to answer Ling Feng's question, he would not go back on it.
Moreover, Ling Feng was here for the body of his relative, giving him no reason to refuse.
Su Xingyan slowly said, "Since you know about Nanyun's Gu Poison arts, you must have heard of the division within Gu Poison, haven't you?"
Ling Feng frowned slightly, shaking his head, then as if recalling something, he nodded and said, "Elder Su is referring to the Witch faction and the Gu faction?"
"You even know about the Witch faction and the Gu faction?"
This time, Su Xingyan was even more astonished. He had intended to refer to the division of Gu Poison into good and evil, but Ling Feng had actually understood the division into two factions.
Ling Feng nodded. "I learned this from Senior Medicine King Bai Yunyan. This time, to save Elder Su, I entered the mountains with the Medicine King to gather herbs, and we were ambushed by people from the Witch faction!"
"So it was that old ghost Bai Yunyan, no wonder!" Su Xingyan nodded, his gaze towards Ling Feng becoming more profound, and his attitude inexplicably improved.
Ling Feng clearly perceived the change in his attitude and felt a sense of curiosity, but he could vaguely guess that it had something to do with Hua Puti and Bai Yunyan.
Perhaps the fact that he had the help and care of these two elders was enough to earn Su Xingyan more trust.
"The art of Gu Poison has a long history. The so-called Gu faction separated from the Witch faction."
After a moment of contemplation, Su Xingyan began a lengthy explanation.
"The world may have heard of Gu arts, and most know their methods are evil, mysterious, and not tolerated by the world. In external rumors, Gu art families only pass down to women, not men! As the ancient saying goes, Nanyun has women who are skilled in Gu, with hearts as venomous as snakes!"
"And these rumors are not entirely true. Gu arts originated from a branch of witchcraft. In ancient times, witchcraft was only passed down to men, not women. As the female tribes were weak, to gain sufficient power, they meticulously studied the methods of cultivating Gu within witchcraft!"
"From the beginning, aphrodisiac Gu and soul-entering Gu were means to bind their husbands, gradually developing into insidious and vicious Gu techniques!"
"Therefore, witchcraft split back then, dividing into the Witch faction and the Gu faction!"
"The Witch faction itself had divisions of good witches and evil witches, while cultivating Gu was originally for healing people, but later its nature completely changed, leading to most Gu factions being evil! With cruel methods!"
Having said this, Su Xingyan's tone softened slightly as he looked at Ling Feng.
Seeing this, Ling Feng nodded slightly. "Elder Su means that this matter was done by people from the Gu faction, not the Witch faction?"
"Indeed!"
Su Xingyan smiled somewhat strangely, giving a chilling impression.
"In that case, the people from the Witch faction earlier were not targeting me."
Ling Feng asserted.
"Heh, of course, they weren't targeting you; you're not part of the Witch faction!"
Ling Feng was taken aback, Su Xingyan's words held a certain depth.
However, before Ling Feng could ponder the deeper meaning, Su Xingyan spoke again. "It's not strange to see people from the Witch faction in Nanyun, but the Gu faction is too mysterious, and those who know how to use corpse-raising Gu, this ancient Gu art, are even fewer! After all, such methods are too inhumane."
"As far as I know, there are only three families that still use corpses to cultivate Gu!"
The truth was getting closer!
Ling Feng's eyes narrowed. "Please clarify, Elder Su! Which three families?"
"These three families are Ba, Shi, and Zu!"
Su Xingyan's expression was exceptionally solemn. Merely mentioning these three families caused his complexion to change, indicating how extraordinary these families were.
"These three families are inherently very mysterious. Even our Su family has had no interaction with them for at least a hundred years. And it is rumored that the Zu family was destroyed by their enemies in their early years! So, only the Ba clan and the Shi family remain!"
Ling Feng pressed further. "Where are the remaining two families located?"
For Ling Feng, one family being destroyed meant one less target to screen, leaving only two made it easier to pinpoint!
But Su Xingyan shook his head with a wry smile. "Heh, I don't know! These two families are nomadic and rarely interact with outsiders, so they are very difficult to find. Nanyun is so vast, if you try to find them, it's like searching for a needle in a haystack!"
Ling Feng's expression changed drastically!
Even Su Xingyan didn't know the whereabouts of the other two families, so how could he find them?
Did this mean that after all his efforts, the clue had once again broken off?
As long as his elder brother Ling Yan's corpse was in their hands for another day, he didn't know how much humiliation it would suffer, something Ling Feng could not bear!
Su Xingyan saw Ling Feng's expression change, and his own face turned red.
Su Xingyan could clearly sense the suppressed killing intent within Ling Feng surging wildly.
It was terrifying, like the collapse of heaven and earth, which turned Su Xingyan's initial wariness into reverence!
Someone who was bloodthirsty would not be able to temper the killing intent within their body to such a degree.
Therefore, in the current world, there was likely only one possibility for someone possessing such killing intent.
That was an ultimate powerhouse who had fought on battlefields for years, standing at the pinnacle amidst mountains of corpses and seas of blood!
As for Ling Feng's true identity, Su Xingyan dared not continue to speculate.
"However! You have come at a very opportune time!"
Su Xingyan suddenly changed the subject, causing Ling Feng's eyes to light up again.
"Elder Su, what do you mean by that?"
"Heh, in half a month, the Gu Poison Assembly will be held! At that time, masters from all walks of the Gu Poison world will gather at Wushen Mountain!"
Su Xingyan's eyes lit up, clearly looking forward to it.
"This time, the Wushen Palace has offered very tempting rewards, so many fellow practitioners of Gu Poison will participate! Perhaps there will be people from the Ba and Shi families, so you can try your luck!"
Su Xingyan said slowly.
With the turn of events, Ling Feng's previously gloomy expression immediately eased.
"Thank you, Elder Su!"
"Heh, don't thank me yet. Since it's a grand gathering held by fellow practitioners of Gu Poison, how can an outsider like you enter so casually?"
