Dugu Yan had never met her parents since she was a child. For more than ten years, it had always been her grandfather who raised her.
When she was a child, Dugu Yan had asked her grandfather where her parents had gone. But every time, her grandfather would always be silent, his face full of a look of deep regret.
Later, her grandfather told her that her father and mother had been killed by a soul beast.
If Tang Si isn't lying, there's probably a hidden story behind my parents' deaths.
"Wait!" Dugu Yan's eyes suddenly contracted. She suddenly thought of something and asked anxiously, "You said my grandfather is also poisoned? How is that possible?"
"Yeah, Senior Dugu is a Titled Douluo. Brother Tang, if you spread rumors about him, your butt will be beaten to a pulp," Osler took over from Dugu Yan and said seriously.
"My guess comes precisely from Senior Dugu. Osler, let me ask you, before Senior Dugu advanced to Titled Douluo, did he have any fame in the soul master world?" Lu Feng asked unhurriedly.
Osler crossed his arms and said with conviction, "How would I know? I wasn't even born then."
Lu Feng gave him a sidelong glance, took a deep breath, and then slowly exhaled.
Seeing this, Osler immediately sat up straight, placed his hands on his thighs, and looked straight ahead.
Ye Lingling thought for a moment and said, "I once heard my grandfather say that Senior Dugu was a genius who appeared out of nowhere."
"In the same era as him, the sect masters of the Lower Four Sects, Senior Dragon Duke of the Exotic Beast Sect—these were all famous figures at the time."
"But none of these people were able to break through to Titled Douluo."
After speaking, Ye Lingling asked with confusion, "But Tang Si, what does this have to do with Sister Yan's snake poison?"
Hearing this, Dugu Yan also stared intently at Lu Feng, eager to know the answer.
After the events of the day, Dugu Yan was completely convinced of Lu Feng's medical skills.
Her grandfather was her only relative in this world. If anything happened to him, Dugu Yan really didn't know what she would do.
"Senior Dugu's martial soul is the Jade Phosphor Serpent Emperor. I speculate that it was an acquired mutation, perhaps because he obtained some kind of opportunity. However, at the same time his martial soul evolved, his body also mutated to have a poison attribute."
Lu Feng said word for word, "This poison is hidden in the bloodline and is passed down from generation to generation. And Miss Dugu's poison is particularly severe. If it cannot be cured, I'm afraid you won't live past the age of thirty."
"What!" Two gasps of surprise sounded at the same time.
"Brother Tang Si, you're not joking, are you?" Osler's expression was serious as he said in a deep voice.
Although Dugu Yan often played pranks on him when they were children, there was no doubt about their relationship.
Ye Lingling also squeezed Dugu Yan's hand, as if to give her some comfort.
Dugu Yan was also a little flustered at this moment, but she took a deep breath and said, "Tang Si, everything you've said is just your speculation."
"I'm not denying you, but what you've said is simply too incredible. I have to go back and confirm with my grandfather," Dugu Yan said in a deep voice.
Lu Feng nodded and said, "It's alright. Just have Senior Dugu come and find me then."
At this moment, Osler spoke up, "Brother Tang Si, since you've diagnosed Sister Yan's poison, do you have any solution?"
Lu Feng glanced at Osler. That's a good question. This kid has finally done something useful.
"Ahem."
Lu Feng coughed lightly, clearing his throat.
"The poison in Miss Dugu's body is something that even Senior Poison Douluo cannot eradicate. It would not be an exaggeration to call it a terminal illness."
Hearing this, the hearts of the group immediately tightened.
Osler couldn't help but lower his head and sigh. Dugu Yan had grown up with him. He had always treated this girl, who was only half a month older than him, as a "mother".
Lu Feng shook his head and sighed, "For this kind of terminal illness, I've temporarily only thought of twelve solutions."
"What! Even you, Brother Tang Si, have no solution?"
"Sigh~, my poor Sister Yan," Osler sighed again.
"Huh?!! Wait, what did you just say?" Osler suddenly reacted, his eyes staring straight.
"Twelve!!!"
"Smack!" Dugu Yan slapped Osler on the back of the head and snapped:
"You, shut up!"
"Hmph!" Osler's face became stern, and he sat up straight.
"Tang Si, what are your methods? If you can solve the snake poison in my grandfather and me, as long as it's something I have, you can name any condition you want!" Dugu Yan patted her chest and said righteously.
"Hahaha, if I were to say 'we are all friends, I'll contribute for free', Miss Dugu would surely think I'm being insincere. Since you've said so, I won't be polite," Lu Feng laughed loudly.
Hearing this, Dugu Yan's heart actually settled a little.
Seeing Tang Si's confident appearance, perhaps he really did have a way.
"The first method, which is both the simplest and the most difficult, is for Miss Dugu to absorb a soul bone to act as a container for the poison," Lu Feng said in a loud voice.
"A soul bone?" Several puzzled voices sounded at the same time.
Lu Feng explained, "As everyone knows, soul bones are known as the 'Supreme Treasures of the Blood River' and can greatly improve a soul master's physical fitness. Miss Dugu can force the poison produced in your body into the soul bone, which will reduce the burden on your body."
"However, the poison in your body is produced continuously. I estimate that the age of this soul bone absolutely cannot be less than sixty thousand years. Moreover, this method treats the symptoms but not the root cause. Your descendants will still need to prepare another soul bone."
"Sixty thousand years?" Osler said in a deep voice.
"I do have channels for soul bones under twenty thousand years, although the price is a bit steep. But sixty thousand years..."
A soul bone of this age could already serve as a sect's legacy. An ordinary soul master would absolutely not sell it.
"The second method is, if you can find a legendary peerless immortal herb, you can cleanse your meridians and marrow. Not only will the snake poison in your body be completely cleared, but your own martial soul might also undergo an acquired evolution, just like Senior Poison Douluo."
"An immortal herb? What is that?" Osler asked, puzzled.
Lu Feng said unhurriedly, "This item should only exist in the heavens; how could it be found in the mortal world? There is one immortal herb that everyone should have heard of, the Exquisite Cockscomb."
Osler scratched his head. Lu Feng's words had once again touched upon a blind spot in his knowledge.
"Are you talking about Senior Chrysanthemum Douluo from the Spirit Hall?" Ye Lingling asked uncertainly.
"Correct, it is Senior Chrysanthemum Douluo's martial soul."
Lu Feng explained, "Senior Chrysanthemum Douluo's martial soul actually exists in reality. This item is a neutral-type immortal-grade herb. Consuming it will circulate qi through the four limbs and open the eight vessels, allowing one to cultivate an indestructible vajra body."
"An indestructible vajra body!" Hearing this, Osler's eyes immediately lit up.
"Smack!"
Dugu Yan slapped Osler on the head again.
"Wuwuwu~" Osler immediately clutched his head and pretended to cry.
Looking at the fooling Osler, Lu Feng shook his head helplessly.
It's really nice to be a carefree second-generation rich kid.
Lu Feng had also thought for a long time about releasing the knowledge of the Exquisite Cockscomb.
In the original work, Dugu Bo and Yue Guan had known each other for decades and had fought many times. They could be said to be both enemies and friends.
Dugu Bo didn't recognize the other immortal herbs, but it was unreasonable that he wouldn't recognize this one.
After getting Dugu Yan on his side, Lu Feng had thought countless times about how to deal with Dugu Bo.
As a Douluo with the title 'Poison', Lu Feng really couldn't believe that Dugu Bo would be a simpleton like in the original work.
Therefore, he would first reveal some real information to Dugu Bo.
Advancing step by step, planning slowly and carefully.
Lu Feng believed that the Ice and Fire Yin Yang Well, Dugu Bo, Dugu Yan, and even her family's dog, would not be able to escape his Five Finger Mountain.
