Urban Immortal Cultivation Supreme

From here, Zhu Bufan directly experienced the principle that medicine and poison are interchangeable.

For instance, some poisonous herbs contain lethal toxins capable of causing death, yet paradoxically, they can cure stubborn diseases.

Thus, it is said that there are no absolutely opposing entities in the world.

"Moon Gazing Rhinoceros Horn one gram, Sunburn Grass one leaf..."

Looking at the ingredients for Yin Yang Reunion Powder, Zhu Bufan sighed in his heart, truly deserving of being ranked as the top elixir of spring! The ingredients used are incredibly precious.

Below, there are four or five types of spring elixirs, including ones like Hopeful Spring Breeze and Red Powder.

...

Having learned about so many poisons, Zhu Bufan now felt an itching in his heart, currently most eager to personally concoct poisons.

"It seems it's time to find an opportunity to go out and wander around."

...

"Still not working!" Zhu Bufan said somewhat dejectedly as he opened his eyes from cultivation.

Now, Zhu Bufan faced his first bottleneck, and having not even touched this bottleneck yet, breaking through was definitely not going to happen overnight.

Since the Cold Ice Technique didn't yield much effect in his cultivation for now, Zhu Bufan shifted his focus onto the Hanhai Tide Skill.

Honestly, regarding this cultivation technique that suddenly appeared in his mind, Zhu Bufan always felt a lingering awkwardness, so, he hadn't tried it in the past three months.

He closed his eyes, familiarized himself with the cultivation route of the First Layer in his mind, then with slow intention, he manipulated the Inner Qi in his Dantian, quickly gathering it into an immensely large vortex.

Just when the vortex formed, Zhu Bufan broke out from the state of cultivation, a heart-wrenching intense pain fiercely struck his brain, making it utterly impossible for him to calm his mind and gather his qi.

Having left the state of cultivation, the Qi vortex lost the support of Zhu Bufan's intention and couldn't maintain itself, dispersing back into Inner Qi within the Dantian.

This sudden intense pain also disappeared untraceably as Zhu Bufan stopped his cultivation.

"Why did this happen?"

Reflecting on the situation just now, Zhu Bufan exclaimed in surprise.

It turned out that when Zhu Bufan activated the Hanhai Tide Skill with his mind, as the Qi vortex in the Dantian formed, it powerfully summoned the Heaven and Earth Primordial Qi around him, rushing into Zhu Bufan's body in a swarm, wildly cleansing his body.

Generally, the physical condition of a martial artist improves along with their cultivation level, as cultivation enhancements gradually unlock new meridians and accumulate more powerful Inner Qi, which naturally gets absorbed by the body, strengthening it.

Of course, there are deliberate methods to strengthen the body, including various physical trainings, martial arts such as palm techniques and fist techniques, and some Heavenly Treasures like Strengthening Body Pills, all of which serve to enhance the body.

But it has never been heard of that, purely by devouring Heaven and Earth Primordial Qi and violently absorbing it into the body, regardless of whether the body can withstand it, forcibly making flesh and bones absorb it to achieve body strengthening.

Heaven and Earth Primordial Qi needs to be refined through Inner Qi Cultivation Methods, firstly because of the endless and complex mixed Primordial Qi, and secondly, due to the violent nature of the Primordial Qi. Without refinement through Inner Qi Cultivation Methods, the body's meridians and Dantian simply cannot endure the turbulent impact of the Qi.

This is common knowledge in cultivation.

However, the Hanhai Tide Skill clearly broke this common knowledge, as it uses the Dantian Qi vortex to absorb Heaven and Earth Primordial Qi in the Postnatal Realm, without any refinement, to strengthen the body.

This appears to be a suicidal act.

But Zhu Bufan did not think so at all; instead, he had an epiphany, looking like he had found a treasure.

The reason for his excitement was only one: the formation of the Qi Vortex in his Dantian.

As everyone knows, when Postnatal Martial Artists cultivate, their demand for external Primordial Qi is minimal. The increase of inner Qi mainly relies on the supply of one's own blood Qi, and the ultimate method to increase blood Qi is to consume various precious supplements.

This is the origin of a common saying: the poor study literature, the rich study martial arts.

However, once one reaches the Innate Realm, they can interact with the Heaven and Earth Primordial Qi, creating immense power with a wave of a hand or a foot.

Now, the Hanhai Tide Skill even allows Zhu Bufan, in the Postnatal Realm, to harness Heaven and Earth Primordial Qi. Even though it's a brute-force unilateral devouring, it's still an earth-shattering act.

"If I can guide it into my Dantian and use the Cold Ice Technique to refine it, then my cultivation speed..."

Thinking of this, a frightening gleam erupted in Zhu Bufan's eyes.

Although the idea was extremely tempting, Zhu Bufan was not conceited enough to think that with his current knowledge and abilities, he could achieve this.

However, he at least now had conditions and a starting point that others could hardly reach.

Just now, sudden severe pain broke him out of his cultivation because he was unprepared. This time, Zhu Bufan made thorough preparations.

Soon, as the Qi Vortex formed in the Dantian, the Heaven and Earth Primordial Qi quickly entered Zhu Bufan's body, guided by the vortex.

Severe pain followed.

Among the many torturous methods historically, the most cruel is the slow slicing execution, inflicting exactly three thousand nine hundred cuts to completely remove the flesh from the body, leaving only stark white bones.

Of course, Zhu Bufan had never experienced how cruel slow slicing was, but now, he felt that he was suffering a pain hundreds of times more intense than that.

Slow slicing cuts the flesh, while the first layer of the Hanhai Tide Skill's Mixed Refinement does not just slice flesh—it crudely scatters the flesh and blood within Zhu Bufan's body, merging it with the Heaven and Earth Primordial Qi to form a superior composition and a more sensible system inside his body, based on destruction.

It was pain indescribable. Zhu Bufan was enduring it only by clenching his teeth with single-minded determination.

Hush hush…

Not long after, light sounds of flowing water emerged from Zhu Bufan's body, and his skin bulged with various-sized air bubbles, as if numerous streams were washing over him.

The Hanhai Tide Skill differs from any other cultivation technique Zhu Bufan knew. As long as he could keep the Qi Vortex in the Dantian stable, there was no need to maintain a deliberate seated, peaceful meditation state.

Keeping the stable rotation of the Qi Vortex in his Dantian, Zhu Bufan slightly opened his eyes. His originally slightly dark skin looked as if it had been scorched by an intense fire, frighteningly red, as if a layer of bright vermilion had been brushed onto his skin.

Yet Zhu Bufan did not feel any scorching heat; instead, because of the intense pain, he felt bouts of chilliness.

Three minutes, Zhu Bufan merely endured for three minutes.

In that agony, every minute and second was extremely difficult, feeling as long as years.

Those short three minutes felt like three years to Zhu Bufan. The constant severe pain left him no choice but to bear it silently. Even the thought of diverting his attention to alleviate the pain was not possible, for if the Qi Vortex dispersed, all efforts would be in vain.

Sigh…

Pausing his cultivation, Zhu Bufan collapsed powerless onto the bed.
