Chapter 716: Breakthrough to the Profound Qi Hunyuan Immortal

Gu An stood still, focusing on manipulating the Lifespan Barrier, eventually expanding its range to cover an area as vast as the Nine Spirits Continent.

He pulled up his attribute panel and poured one hundred billion years of lifespan into his physique.

Last time, he used forty billion years of lifespan to evolve from the Hunyuan Reincarnation Immortal Physique to the Hunyuan Dao-Creating Physique. This time, even one hundred billion years might not be enough to level up again.

This time, he wasn’t aiming to boost everything—he just wanted to break through his cultivation realm. Improving his physique now was mainly to test how fast the Lifespan Barrier consumed lifespan.

One prompt after another quickly popped up before him.

Even after burning one hundred billion years of lifespan, his physique didn’t level up.

Since he’d already started, he had to see it through.

Gu An kept pouring in lifespan, one hundred billion years at a time.

The lifespan he burned this time was way more than he expected, quickly surpassing one trillion years. That made him regret it a bit.

The leap was massive, from forty billion to over one trillion.

Gu An suddenly felt like one hundred trillion years of lifespan wasn’t such a big deal after all.

In the end, his Hunyuan Dao-Creating Physique transformed into the Hunyuan Boundless Dao-Creating Physique, costing him a total of five trillion years of lifespan.

From forty billion to five trillion, more than a hundredfold increase!

And it only added two words—"Boundless"?

Gu An took a deep breath. The Dao spirit energy in the Supreme Yuanlin suddenly surged and flooded into his body.

He turned his attention to the Lifespan Barrier, watching the numbers drop faster, but still within an acceptable range.

Soon after, waves of profound Dao insights rushed into his mind, forcing his consciousness to immerse completely in comprehension.

The Lifespan Barrier kept drawing Dao spirit energy from the Supreme Yuanlin, triggering all sorts of strange phenomena. Fierce winds carrying Dao laws howled through the massive source trees, and the silver-blue Qi Sea below churned with growing intensity.

Half an hour passed.

Gu An had fully evolved into the Hunyuan Boundless Dao-Creating Physique. As he opened his eyes, the Supreme Yuanlin was still in turmoil, each source tree wrapped in countless blue stars, lighting up the entire realm.

He didn’t spot any other living beings, so he focused again on the lifespan cost of maintaining the barrier.

Over three hundred billion years!

Still manageable!

He now had nine quadrillion four hundred trillion years of lifespan left. For some reason, it was starting to feel a bit tight.

He took a deep breath, cleared his mind, and began pouring lifespan into his cultivation.

Starting with one trillion years!

【You refined Qi for one hundred billion years. Using the Great Mastery of the Ten Thousand Dao Annihilation Art, you forcefully attempted to reach the Hunyuan Dao Fruit realm and began your tribulation. You failed to survive the Dao Inquiry Hunyuan Nine Yang Grand Tribulation. Tribulation failed.】

【You refined Qi for two hundred billion years. Using the Great Mastery of the Ten Thousand Dao Annihilation Art, you forcefully attempted to reach the Hunyuan Dao Fruit realm and began your tribulation. You failed to survive the Dao Inquiry Hunyuan Nine Yang Grand Tribulation. Tribulation failed.】

…

Each attempt cost one hundred billion years!

Damn!

Back when he was breaking through to Dao Extreme Grand Luo Immortal, each attempt only cost him twenty billion years. This clearly showed how vast the gap was between Dao Extreme Grand Luo Immortal and Hunyuan Dao Fruit.

Even though the pressure was intense, it made Gu An look forward to it more.

His last major breakthrough cost him two trillion three hundred billion years of lifespan. This time, he figured he’d break through within fifty trillion.

Gu An watched the prompts, calculating silently.

In the end, even after burning through one trillion years, he still failed.

Without flinching, Gu An kept pouring lifespan in—another one trillion years in one go.

The strange phenomena in the Supreme Yuanlin were gradually calming down. Those massive source trees flickered with all sorts of silver-blue light, making the whole world feel surreal.

After a while.

Gu An’s expression started to shift.

Even after burning ten trillion years of lifespan, he still hadn’t broken through.

It seemed like there was no way he could fully reach the perfect stage of this new major realm.

No matter what, he had to break through this realm first!

Gu An’s eyes turned firm, and he continued pouring in more lifespan.

But even after spending another ten trillion years, he still failed. His mind began to imagine the Dao Inquiry Hunyuan Nine Yang Grand Tribulation—just how terrifying was this tribulation really?

At some point, he’d have to ask Yang Jian and Li Xuanmiao to check the Heavenly Tribulation records in the Heavenly Court, so he could understand the difficulty of the tribulations he was facing.

Some more time passed.

Gu An had already spent over forty trillion years of lifespan trying to break through his cultivation, still without success.

He kept going.

【You refined Qi for five trillion four hundred billion years. Using the Great Mastery of the Ten Thousand Dao Annihilation Art, you forcefully attempted to reach the Hunyuan Dao Fruit realm and began your tribulation. You failed to survive the Dao Inquiry Hunyuan Nine Yang Grand Tribulation. Tribulation failed.】

【You refined Qi for five trillion five hundred billion years. Using the Great Mastery of the Ten Thousand Dao Annihilation Art, you forcefully attempted to reach the Hunyuan Dao Fruit realm and began your tribulation. You survived the Dao Inquiry Hunyuan Nine Yang Grand Tribulation. Tribulation successful. Your cultivation broke through to the early stage of the Profound Qi Hunyuan Immortal Realm.】

【You refined Qi for one trillion years. Your cultivation has increased.】

…

Finally, he succeeded!

From reaching perfection in the Dao Extreme Grand Luo Immortal Realm to stepping into the early stage of the Profound Qi Hunyuan Immortal Realm, it had cost him a total of forty-three trillion five hundred fifty billion years of lifespan!

That was insane!

But as long as he succeeded, that was all that mattered. Gu An felt refreshed, eager to see the strength of the Profound Qi Hunyuan Immortal.

The Dao spirit energy of this realm suddenly surged, the gray sky above lighting up. Gu An saw a mountain, incomparably massive, larger than the entire Heaven Spirit Great World itself.

No.

That wasn’t a mountain—it was a source tree!

Gu An narrowed his eyes. Behind that source tree, he saw something even bigger.

This realm, too, was boundless. Even with his Dao Extreme Grand Luo Immortal cultivation, he couldn’t see the end of it anytime soon.

As Gu An was breaking through, the Dao laws within the Supreme Yuanlin began to go wild. Unlike before, now the Dao rules were turning dangerous, space itself twisting.

It was as if the Dao, sensing danger, was instinctively resisting. When the Dao gets angry, the world it creates naturally falls into chaos.

The silver-blue Qi Sea beneath Gu An churned violently, like a sea caught in a storm, with waves growing higher and higher.

Suddenly.

Gu An’s gaze swept into the distance. He sensed a terrifying aura coming from one of the faraway source trees. It was stronger than any Dao Extreme Grand Luo Immortal, and it was searching for the cause of the Dao’s turmoil.

“What a powerful presence, and it seems to be closely tied to the source trees here. Could it be that this Supreme Yuanlin was created by him? Was the layout of these source trees actually a grand formation set by him?”

Gu An stayed on alert, but thankfully, that being didn’t head his way.

Even a being stronger than a Dao Extreme Grand Luo Immortal couldn’t detect the Lifespan Barrier.

As Gu An pondered this, he suddenly felt countless auras surging up from beneath the blue Qi Sea, unstoppable and overwhelming.

Boom!

Far off, where the giant waves were crashing, the blue Qi Sea exploded. Countless silver Qilins of all sizes burst forth, racing toward the sky.

Gu An could sense how powerful these silver Qilins were. The weakest among them had the cultivation of a Free Immortal, and the strongest even reached the Heaven-Opening Grand Luo Immortal Realm.

As they charged, the chaotic Dao rules actually avoided them, not harming them at all. This made Gu An feel curious about these silver Qilins.
