"So it's the Black Flame Begonia, no wonder it has such intense toxicity," Wulu looked at the eerie large flower in the center of the pond and said with a smile.

After speaking, he stepped forward, squatting at the edge of the black pond, and took a deep breath.

Black toxic smoke was seen being inhaled into his nasal cavity, and a cloud of black energy immediately appeared on his face, with black veins throbbing on his forehead.

Wulu's hands slightly clenched into fists, his entire body faintly glowing with purple light, and the blackness on his face quickly dissipated, revealing a look of satisfaction.

"Is Wulu using the venomous power for cultivation?" Yuan Ming thought as he watched this scene.

If this is true, then the "Ten Thousand Poison Evil Skill" indeed has some tricks.

Wulu sniffed his nose, turned his wrist, and took out a half-foot-long short dagger, entirely black, with the blade engraved in purple patterns depicting a bird poised to capture prey, its beak precisely the dagger's tip.

He held the short dagger in one hand and waved it a few times before stabbing it towards the Black Flame Begonia.

With a "hiss," the dagger tip pierced the center of the flower bud.

Immediately, a purple glow appeared on the dagger, as if it were sucking, continuously drawing strands of black poison liquid from the large black flower into Wulu's body.

The hand holding the dagger turned black and blue, followed by the wrist, arm, and finally reaching the chest.

Before long, even half of his face was stained black, the color deeper than before.

Wulu's brow furrowed, and the spot where veins throbbed on his forehead continuously pulsed, as if he was enduring immense pain, and his breath became chaotic.

Even though Nan Shangfeng didn't have the Eyes of Golden Flame skill, he could see Wulu's condition and couldn't help but sweat.

Then, Wulu suddenly erupted in a burst of blood light, and a set of blood-colored armor emerged, encompassing his whole body, the Blood Puppet Armor, instantly stabilizing his chaotic breath.

He immediately sat cross-legged, seemingly operating the "Ten Thousand Poison Evil Skill."

The Black Flame Begonia withered rapidly at a visible speed, and the small pond where it was planted quickly shrank, soon absorbed completely.

The black smoke ascending into the air disappeared, and the clouds in the sky, lacking a continuous supply of toxic smoke, quickly dissipated.

After absorbing all the deadly toxins, Wulu continued to meditate, changing his posture into a strange one, with one leg crossed and the other raised.

His body alternated between green and white, starting with bulging veins of black and blue on his arm and forehead, and later, nearly all his veins bulged, twisted like centipedes.

Wulu's brow wrinkled, and his teeth clenched with a grinding sound, clearly enduring extremely intense pain.

"Is he alright like this?" Nan Shangfeng asked with some concern.

"No problem, his current state should be related to his cultivation technique," Yuan Ming shook his head, saying.

However, just as he finished speaking, black blood suddenly flowed from both the corner of Wulu's mouth and eyes.

Before he could step forward to check, a wisp of faint black smoke emerged from the top of Wulu's head, and his complexion gradually went from blue to white, seemingly relieved of some pain.

Subsequently, all the unusual conditions on his body gradually disappeared, and he returned to normal.

However, when he opened his eyes, besides fatigue, a trace of joy flashed in them, as if his cultivation had advanced.

With the deadly toxins absorbed by Wulu, Yuan Ming and Nan Shangfeng flew over.

"You scared me to death just now," Nan Shangfeng sighed in relief, stepping forward.

"Sorry for worrying you," Wulu smiled.

"That dagger of yours doesn't look like an ordinary spiritual treasure," Yuan Ming remarked, looking at the dagger placed aside.

Wulu picked up the dagger, shook it, and said:

"This is a poisonous spiritual treasure I obtained along with the 'Ten Thousand Poison Evil Skill,' named the Ten Thousand Gods Poison Dagger. It can devour toxic substances, enhancing the dagger's power and transferring the absorbed toxins to its owner. It's indispensable for my battles and cultivation now."

"From your recent cultivation display, it seems the 'Ten Thousand Poison Evil Skill' requires constantly absorbing toxins to cultivate, right?" Yuan Ming asked.

"Yes and no. The cultivation of 'Ten Thousand Poison Evil Skill' has two parts: the advancement of mana and the refining of toxins. Regular cultivation only requires the advancement of mana, but each level breakthrough needs enough toxins to borrow their power to break through," Wulu explained.

"This kind of risky cultivation technique is truly dangerous," Yuan Ming said with a frown.

"Day-to-day cultivation is fine; only at the bottleneck of mana transformation do difficulties arise. Recently, my cultivation has progressed rapidly, nearing the early-stage peak of Returning to Void, preparing to advance to mid-stage, so I urgently need to store some toxins," Wulu stated.

"May I take a look at your physical condition?" Yuan Ming said.

Wulu hesitated for a moment but eventually nodded, putting away the Blood Puppet Armor.

Yuan Ming concentrated his mind, and his Divine Sense surged forth, penetrating Wulu's body. His expression quickly turned grave.

Wulu's mana was filled with poison, and his body was also saturated with toxins, which were trapped in his Dantian, palms, and soles by his mana through some mysterious method, preventing them from spreading.

However, the toxins were dangerously close; no matter how profound the "Ten Thousand Poison Evil Skill" was, it couldn't completely control all the toxins, and inevitably, there were leaks. Wulu's internal organs had been significantly corroded.

Fortunately, Wulu had profound cultivation and the regenerative abilities of the Blood Puppet Armor, allowing him to withstand the toxins for now.

"Such a sinister cultivation technique. If I'm not mistaken, each breakthrough is like a life and death ordeal. If successful, all is well, but if not, the poison backlash will lead to death and disappearances." Yuan Ming said slowly.

"Fellow Daoist Wan's observation is indeed correct." Wulu nodded.

"With such a dangerous cultivation technique, why not abandon it? Brother Wulu, if you're not opposed, I have several Returning to Void techniques here, all quite exquisite..." Nan Shangfeng, deeply alarmed, took out several Jade Scrolls and handed them over.

"Thank you for your kind offer, Brother Nan. Although the 'Ten Thousand Poison Evil Skill' is indeed sinister and overbearing, making it perilous to cultivate, its prowess in combat is extraordinary. It's also a rare technique that directly leads to the Mahayana Realm. I, although not confident, still wish to reach the peak of Mahayana." Wulu smiled nonchalantly.

Seeing Wulu's determined eyes, Nan Shangfeng sighed and put away the Jade Scrolls.

"From what I've observed earlier, the most challenging part of the 'Ten Thousand Poison Evil Skill' should be gathering and merging all kinds of toxins with mana, correct? I noticed during your cultivation that you seemed to use 'Void Thought Technique.' Do you rely on this technique's divine skills of refining different species magic power to meld toxins with mana?" Yuan Ming inquired once more.

"Have you studied other poison skills?" Wulu looked surprised.

Yuan Ming hadn't studied other poison skills, but he had encountered numerous techniques. With his high cultivation realm, he could often guess the gist at just a glance.

However, he didn't explain explicitly, only nodded and said, "Void Thought Technique, while mysterious, mainly excels in refining magic power, not in melding toxins. Currently, your cultivation is still shallow, allowing you to suppress the toxin backlash, but as your cultivation deepens, sooner or later..."

Yuan Ming stopped midway, not finishing his sentence.

Wulu just smiled and said, "I understand your meaning. Indeed, luck played a significant role in my successful cultivation to my current realm. I'm not confident about how far I can go in the future. Perhaps the next breakthrough attempt will result in my death from my own toxins, but..."

Here, he paused.

"Isn't cultivation like climbing a perilous peak? Brother Wan, your path to breakthroughs wasn't a smooth journey either, was it? Besides, I quite enjoy the feeling of walking between life and death. Only when constantly facing fatal dangers do I truly feel alive," Wulu laughed.

Yuan Ming nodded noncommittally, knowing Wulu's past and refraining from further persuasion.

He pondered for a moment and then spoke, "Since your mind is made up, I won't say more. However, I have something quite compatible with your poison skill."

"What is it? Let me see." Wulu's interest was piqued immediately.

With a wave of his hand, Yuan Ming made a sphere of purple light flash before him, revealing a round piece of purple jade that seemed to breathe like a living thing.

"This is the Purple Extreme Tai Sui!" Both Wulu and Nan Shangfeng quickly recognized the artifact.

"Your eyesight is quite sharp. This is indeed the Purple Extreme Tai Sui, currently considered a Level 4 Demon Beast. You must be aware of its abilities?" Yuan Ming asked.

"I've heard of it. The Purple Extreme Tai Sui can devour poisonous substances and fuse various toxins to generate a new, stronger poison, hence it's called the Tai Sui of Ten Thousand Poisons. With this, I won't have to worry about finding more potent poisons. As long as I keep feeding it toxins, the Purple Extreme Tai Sui can naturally generate deadlier poisons for me," Wulu exclaimed in surprise.

"Not only that, but the ability of the Purple Extreme Tai Sui to merge poisons can also shield you. If you suffer from toxin backlash in the future, this beast can use its ability to save you," Yuan Ming added.

Wulu was so overwhelmed with excitement that he was momentarily at a loss.

"Yuan... Brother Wan, the abilities of this beast are equally valuable to you. I can't accept it," he realized suddenly and waved his hand to decline.

"I have now cultivated an Undying Body and have no use for this beast. Besides, I encounter poisons rarely, so keeping Purple Extreme Tai Sui with me would stifle its potential. Please, don't refuse," Yuan Ming chuckled.

Wulu hesitated, still looking at the Purple Extreme Tai Sui.

Beside them, Nan Shangfeng had been listening to their conversation, and his expression was complex.

The Purple Extreme Tai Sui was an exceedingly rare demon beast in the Chuyun Realm and held immense value for poison cultivators. If a Level 4 Purple Extreme Tai Sui were auctioned in the Ten Thousand Goods Immortal Trip, its price could easily reach millions of Spirit Stones.

Such an invaluable treasure, yet Wan Tianren wanted to give it away so casually.

Nan Shangfeng found it baffling. In his impression, Wan Tianren, despite his vast expenditures, spent primarily on purchasing top-grade spirit wood and seldom squandered wealth randomly, nor was he often so generous.

Only today did he realize that Wan Tianren could be so magnanimous with friends, earning his admiration.
