However, the moment Dugu Bo saw this herb, his pupils shrank violently, and his face instantly turned an ashen gray.
"Thump." Dugu Bo's body stumbled back two or three steps. He lost his footing and fell directly to the ground.
"Sou!" Dugu Bo's body instantly shot into the air. He pointed at the herb in Lu Feng's hand and shouted sternly, "Kid, are you trying to murder me?!"
Dugu Bo had studied most of the Immortal Herbs in the Ice and Fire Yin Yang Well. This was the only one he didn't even dare to touch.
When he first arrived here, he had accidentally come into contact with this Immortal Herb. Unexpectedly, the toxins in his body had erupted violently, and he had almost died on the spot.
From then on, a shadow had been cast in his heart regarding this herb. He even specifically built a fence to enclose it.
A dark line appeared on Lu Feng's forehead. This old fellow... is there any need to be so paranoid?
Lu Feng stepped forward, held up the Immortal Herb, and explained, "Old man, this herb is called the 'Snowy Swan's Kiss'. It is non-toxic itself. Its only effect is to make any poison it touches erupt with ten or even a hundred times its power."
He continued, "Doesn't your Soul Core convert the toxins in your body into soul power? If you consume this herb, wouldn't your combat power instantly increase several times over?"
Unexpectedly, Dugu Bo snorted coldly and said righteously, "I see you're clearly trying to poison this old man, then take the opportunity to seize my granddaughter, take my medicinal garden, and inherit my property!"
"Huu..." Lu Feng slowly exhaled. Sometimes, Lu Feng really wanted to crack open this old codger's head and see what he was thinking about all day.
"Tch, take it or leave it." Lu Feng pursed his lips, placed the Immortal Herb on the ground, and turned to leave.
Watching Lu Feng actually walk away, Dugu Bo's eyes darted around. He shouted, "Kid, are you sure this herb is fine?"
Lu Feng stopped, the corners of his mouth tilting up slightly. "Old man, to be honest, I'm not entirely sure either. But don't worry, if you kick the bucket, I'll take good care of Yan Yan. Oh, right, what's your voucher for the Heaven Dou Bank? You can tell me now, and then write a will or something, just so it doesn't end up benefiting some outsider."
"Hehe, hearing you say that, this old man is relieved." Dugu Bo chuckled and picked up the Immortal Herb from the ground. However, he didn't touch it directly, instead enveloping it with his soul power.
"Summon your Soul Core and directly absorb the energy from the petals. Pay attention, don't touch the roots, or else I'll have no choice but to inherit your estate with tears in my eyes," Lu Feng joked.
Dugu Bo placed the herb in front of him and sat down cross-legged. A dazzling crystalline core rose from his dantian and was slowly spat out from his mouth.
As his soul power surged, a crystalline, snow-white wisp rose from the petals and wrapped around the surface of the Soul Core, making it shine brightly.
Suddenly, the nine soul rings on Dugu Bo's body emitted a dazzling light. A thunder-like growl rumbled in his throat, and his entire body trembled in a strange rhythm.
From his ferocious expression, it was clear he was currently enduring immense pain.
Old fellow, hang in there! Lu Feng inwardly sweated for Dugu Bo.
In truth, his giving this Immortal Herb to Dugu Bo did involve an element of gambling.
Although the Immortal Herbs of the Ice and Fire Yin Yang Well had many magical effects, for experts at the Titled Douluo level, most of them were useless.
Soul Masters who could cultivate to this realm all possessed superior Martial Soul strength, aptitude, and foundation. Take Dugu Bo as an example: his soul power was level 94. There were truly very few Immortal Herbs suitable for him.
Lu Feng had combined this with the characteristics of Dugu Bo's 'Poison Soul Core' and pondered for a long time before finally selecting this herb.
After a long time, Dugu Bo's breathing finally stabilized. A faint white mist emerged from the surface of his skin, hovering and fluctuating around his body.
Lu Feng inwardly nodded, letting out a sigh of relief. Immediately, he took out a black, gelatinous object from his Soul Tool.
Black Jade Paste, the Strength Clan's exclusive secret formula. When prepared in a medicinal bath with a few supplementary herbs, it could enhance a Soul Master's physical strength and resilience.
The Soul Masters of the Strength Clan were all robust and swift. Aside from their genetics and daily smithing training, this Black Jade Paste was responsible for at least one-third of their physique.
The Strength Clan's annual production of Black Jade Paste was only about five kilograms. Dugu Bo demanding 2.5 kilograms at once was probably more painful for Tai Tan than being slapped in public.
"Bang." With a dull thud, a large wooden tub landed heavily on the ground.
Filling it with clean water, Lu Feng took out several herbs from his Soul Tool and placed them inside one by one. Before long, a rich medicinal aroma wafted over.
Lu Feng placed the Black Jade Paste into the tub. Within a few breaths, the liquid inside turned a deep brown. He casually stirred the liquid, twitched his nose, and revealed a satisfied smile.
"Plop." Lu Feng stripped off his clothes and jumped directly into the tub.
"Hiss..." The cold liquid enveloped his body. Lu Feng couldn't help but shiver, and he immediately felt his spirits refresh.
Lu Feng sat cross-legged, the water level just reaching his chin. His soul power surged, and the medicinal properties in the liquid were slowly absorbed.
Gradually, the liquid in the tub actually began to heat up. A warm sensation came from all directions. The cozy, warm comfort made Lu Feng's body go slightly soft, and he almost moaned aloud.
After undergoing the Ice and Fire Body Tempering, Lu Feng's physical strength had greatly improved, especially his resistance to elemental attacks.
However, the strength of his muscles and bones had not yet reached its limit.
In the original work, after the Soul Master tournament finals, Tang San underwent a period of smithing training. Under the impact of the waterfall, his body was like a piece of raw iron, hammered and refined a thousand times, and was finally polished to perfection.
Lu Feng's use of this Black Jade Paste to temper his body served the same purpose.
As time passed, the color of the liquid in the tub gradually lightened. After about an hour, the liquid had become completely transparent.
"Splash!" Lu Feng stood up from the tub and stretched his body hard. A series of cracking sounds came from his bones, as if his entire person had been stretched out.
For this medicinal bath, Lu Feng had only used about 0.25 kilograms of Black Jade Paste. According to the Strength Clan's formula, this was already the maximum dose. Any more, and his body would likely be unable to withstand the potent medicinal power, leading to adverse effects.
Similarly, this kind of medicinal bath could only be done once a month at most.
At this moment, the muscles on Lu Feng's body had become extremely defined. Under his fair skin, a faint yellow halo seemed to flow, making him look full of power.
Lu Feng rinsed his body with clean water from the side, put on a pair of pants, and, bare-chested, began to clean up the residue in the tub.
It was now night, the sky full of stars. In the quiet, the chirping of insects and calls of birds sounded intermittently.
Dugu Bo sat quietly cross-legged on the open ground, steadily absorbing the Immortal Herb's medicinal power. Only the roots of the Snowy Swan's Kiss remained; its medicinal power had been completely absorbed. The reason Dugu Bo hadn't woken up yet was likely that he was trying to break through his soul power bottleneck.
Lu Feng took two deep breaths of fresh air and strode toward the cave.
At the Titled Douluo level, closed-door cultivation sessions often lasted for several days. Lu Feng estimated Dugu Bo wouldn't wake up for at least three days.
"Huh?" From a distance, Lu Feng saw that the light in the cave was actually on. When he walked into the cave, he found Dugu Yan sitting there alone, looking bored.
Hearing the footsteps, Dugu Yan turned her head to look at Lu Feng.
"Ah! You pervert!"
