"Oh?" Fang Yuan's gaze sharpened. "Is that so? What exactly did he divine?"
"It is said that Dongfang Changfan performed a divination for each family, covering aspects such as Gu recipes, locations of Immortal Gu appearances, and essential techniques for killing desolate beasts. He has already divined many things about you. I naturally don't know the specifics, but now everyone knows that you are not a native Gu Master of the Northern Plains. However, you do have Northern Plains Gu Masters by your side, colluding with you," Hei Lou Lan replied.
Tai Bai Yun Sheng, who was listening, couldn't help but shrink his pupils and speak with a sense of dread. "He has already deduced so much? As expected of Dongfang Changfan..."
Hei Lou Lan sneered coldly and continued, "Fang Yuan, our lives are tied together! If I die, it's hard to guarantee that I won't expose you and Tai Bai Yun Sheng. Also, is the Wisdom Gu in your hands?"
Tai Bai Yun Sheng's expression changed slightly. He was about to deny it, but held back the impulse.
Fang Yuan smiled calmly. "How is that possible! The Wisdom Gu was already destroyed by the Great Harmony Wind Wall. How could I have brought it here?"
Tai Bai Yun Sheng secretly praised him in his heart. Fang Yuan's lying skills were truly astonishing. His tone, expression, and demeanor were flawless, filled with feelings of regret and pity, as if he had really missed the opportunity to obtain the Wisdom Gu.
Hei Lou Lan couldn't see through him either. But in the next moment, she squinted her eyes and spoke in a rogue-ish tone. "I don't care if you really lost the Wisdom Gu. I only know that the Wisdom Gu might have come to you to survive. Hehe, don't rush to deny it. I'm sure you already understand what I mean. Hiding in Central Continent is not safe for you. Regardless of whether the Wisdom Gu is really in your hands, if I leak the news that you have it, hiding at the ends of the earth will be useless! Gu Immortals all over the world will crazily hunt you down until they find out the truth."
"Are you threatening me?" Fang Yuan's face turned cold as he slowly stood up.
"Hei Lou Lan, you have some nerve. Do you know that you are currently in the Soul-bereft Mountain? If we give the order, the Land Spirit will fully activate the Soul-bereft Mountain, and you will die here!" Tai Bai Yun Sheng shouted sternly.
Hei Lou Lan, however, threw her head back and laughed, without a trace of fear. "Hahaha, what are a mere dragon's pool and tiger's lair to me? I made preparations before I left. If I don't return within three days, the entire Northern Plains will be spreading the news that you two are the true culprits behind the collapse of the True Yang Building in the Northern Plains, and I will let the world know that the Wisdom Gu is in your hands!"
Tai Bai Yun Sheng's expression froze. Hei Lou Lan had indeed come prepared, and this move struck right at his Achilles' heel.
But at this moment, a gloomy sentence from Fang Yuan made Hei Lou Lan's laughter abruptly stop. "Hei Lou Lan, I know you aren't afraid of death. But have you forgotten your deep-seated hatred?"
Hei Lou Lan's expression changed, and her momentum sank. She looked straight at Fang Yuan with lightning eyes. "State your conditions."
"First, you must agree to return Fixed Immortal Travel to its rightful owner, to me." Then, Fang Yuan raised four fingers. "Second, after we join forces, during your revenge, the spoils of war will be split forty-sixty in your favor. After all, Tai Bai Yun Sheng and I are two Gu Immortals."
Hei Lou Lan snorted. "Do you think you're the only one with helpers? But whatever, I'll agree to this."
She hesitated in her heart but still chose to give in slightly, despite her usually tough temperament.
Fang Yuan smiled slightly, seeing from this the sincerity of her cooperation. He continued, "Finally, I must know the ins and outs of everything. The reason you want to murder your own biological father."
Hei Lou Lan was silent for a moment, then agreed. "You really are paranoid. I can satisfy you on this third point too. Actually, it's not something that can't be shared."
Over the following conversation, Fang Yuan finally learned the secret of Hei Lou Lan's revenge.
It turned out that the root of it all lay in the Eighty-Eight True Yang Building.
Inside the True Yang Building, there was a True Inheritance called the "Yin Yang Longevity Method," which was taken by Hei Cheng in the early years.
Fang Yuan had happened to see the empty shell of a light cluster left behind by the Yin Yang Longevity Method.
This True Inheritance was a life-extending technique created by Giant Sun Immortal Venerable through studying the Human Ancestor.
To use this method, two Gu Immortals, one male and one female, were needed to cooperate. Through intercourse, the goal of extending one party's lifespan could be achieved.
However, there was a drawback.
If one party's life was extended, the other party would have their lifespan shortened.
In a word, it transferred the lifespan from one person to another.
The story of Su Xian'er's Night Run had long been widely spread throughout the Northern Plains, inspiring countless young maidens of the Northern Plains to take the initiative and seek their own romantic destiny.
Over two hundred years ago, Su Xian'er was a daughter of the Su family born of a concubine. She held a low status and often served as a wine-pouring maid at banquets entertaining distinguished guests.
Once, the patriarch of the Su family entertained Hei Cheng. Su Xian'er poured wine for him and fell in love at first sight.
However, the Su family patriarch secretly plotted against Hei Cheng. Hei Cheng was planted with a poison Gu, his strength plummeted to rock bottom, and he was hunted down.
After Su Xian'er accidentally found out, she resolutely ran out of the family camp in the middle of the night to rescue Hei Cheng, whom she had only met once.
At the time, she was only at the first rank. The wolf packs of the Northern Plains roamed at night, with danger lurking everywhere. She was practically seeking death.
But by a stroke of serendipity, she found Hei Cheng collapsed and unconscious on the ground.
Hei Cheng was thus saved. The conversation between the two subsequently became a classic tale widely praised by the people of the Northern Plains.
