In any part of the stellar space, cultivators can cultivate because stellar space energy is omnipresent, yet the efficiency is extremely low.

Just like the Nine Provinces cultivators, who can cultivate anywhere within the Nine Provinces, though very few actually do so. Even Spirit Stream Realm cultivators know to head to the Spirit Stream battlefield...

The cultivation environment of this reef island is better than ordinary stellar space. If a cultivator doesn't have high demands for a cultivation environment, they can totally cultivate here. Naturally, the efficiency is somewhat lacking compared to using spirit jade or consuming elixir pills, but it has the advantage of being a cost-free deal.

But basically, no one does this because it's too unsafe. There's always someone flying back and forth overhead, so who can cultivate in peace? Especially since normal cultivators need to keep their minds focused during cultivation, making it easy to get ambushed.

Of course, if one is within a Spirit Island occupied by a major force, then there's no need to worry about this issue.

The ferryman, Fang Wanli, said that in some Spirit Islands, the stellar space energy is very rich and can completely satisfy the cultivation needs of Constellation cultivators. If someone can occupy such a Spirit Island, just the cultivation resources alone can save a lot.

And in the All Phenomena Ocean, there are quite a few of these Spirit Islands.

This is one of the reasons all forces are keen to contest the ownership of Spirit Islands. To them, Spirit Islands are not only places they can settle in, but also a kind of cultivation resource in themselves!

There's another more important reason, and that is Spirit Jade Veins within the Spirit Island, which is what makes the forces from the four galaxies envious.

Currently, of the Spirit Islands occupied by various forces, 70% have Spirit Jade Veins of varying sizes inside, and only the remaining 30% are barren islands.

In the stellar space, there are countless domains of various sizes, but only the top domains can nurture Spirit Jade Veins. But how many top domains are there throughout the entire stellar region?

Most are large domains without Spirit Jade Veins inside, but as long as one has enough power, one can seize a vein here.

What especially makes people envious is that each Spirit Jade Vein here is renewable. In other words, as long as one controls the mining speed and frequency, it will never be exhausted. This is because the root cause of the Spirit Jade Veins lies in the All Phenomena Ocean, and unless one day the All Phenomena Ocean disappears, these Spirit Jade Veins will persist. During the mining process by cultivators, the veins will continually absorb the energy from seawater and condense into new spirit jade.

These things are still quite distant from Lu Ye. He came here merely to confirm two things.

The first is naturally the speed of cultivation.

Having just advanced to the Constellation Mid-Stage, the speed at which he consumes spirit jade is bound to be faster than before, so he wonders how much he will need per month.

Nearly three years ago, when he first advanced to Constellation, he experimented and concluded that he only needed to consume 120 pieces of spirit jade per month to meet his cultivation needs.

Later, as his strength gradually grew, this consumption also increased, but only by a small margin. Before advancing, Lu Ye estimated that less than 200 pieces of spirit jade per month would be sufficient.

Now, he needs to figure out his consumption after the advancement.

He took out two pieces of spirit jade and held them in his palms, using the power of the Talent Tree to refine them at the maximum speed his body could accept. This allowed him to achieve the highest cultivation efficiency and avoid wasting any spirit jade.

Three days later, Lu Ye concluded.

The current monthly demand for spirit jade is about 400 pieces!

The consumption has doubled! And this is just the state right after advancing. As his strength increases and the refinement depth of his bone marrow essence grows, it will definitely become more and more.

Feeling bitter inside...

He only has just over 500 spirit jade left in his hands; isn't that barely enough for a month's cultivation? How is he supposed to carry on?

After slightly calming himself, he took out the 24 Dragon Breath Crystals he had purchased at a high cost and used the power of the Talent Tree to absorb them, replenishing the fuel reserve of the Talent Tree.

Feeling the increase in the Talent Tree's fuel reserve, his mood improved slightly.

Indeed, a Dragon Breath Crystal worth 760 pieces of spirit jade lives up to its value. The intensity of the fire-type energy stored within is at least a hundred times greater than the Earth's Core Fire he initially encountered, making it incomparable.

In this way, in the short term, he does not need to worry about the fuel for the Talent Tree.

He sat cross-legged on the reef island for a long time, originally intending to wait until there was no one around to verify the second matter, but no suitable opportunity arose no matter how long he waited.

There's always someone flying back and forth overhead.

He decided not to wait any longer.

He stood up and walked to the edge of the island, gazing into the deep sea before him.

Meanwhile, in the mid-air not far away, two figures flew side by side. One was an elderly man with white hair, and the other was a fresh and beautiful young girl. The girl was only at the Constellation Early Stage, and her spirit force fluctuations seemed a bit unstable, clearly having just advanced to the Constellation level not long ago.

Everything seemed novel to her as a newcomer.

The elderly man flew forward with her, constantly saying something to her, and the young girl's little head kept nodding.

Suddenly, upon seeing Lu Ye, she pointed: "Master, look, someone's about to jump into the sea. Could it be that something's bothering him?"

The elder raised his hand and slapped her arm down, admonishing, "Do not point recklessly, and do not speak nonsense. This All Phenomena Ocean is formed from an extremely rich concentration of stellar space energy. Although we Constellation cultivators have begun to absorb stellar space energy for our own use, to strengthen ourselves, too much of anything can be harmful. Even for a Sun Blaze, this seawater is a highly toxic substance. Hardly anyone is willing to delve into it lightly. This is common knowledge in the All Phenomena Ocean. Who would jump into the sea unless they've lost their minds? You must remember this in the future..."

"Plop…" A light sound came from below.

The young girl said, "He's lost his mind!"

The elder's eyelid twitched as he quickly paused in mid-air, utterly puzzled at how someone could be so foolish in this world.

"Master, should we save him?" The girl looked worried.

The elder hesitated, then shook his head, "No need. This person is probably new to the All Phenomena Ocean and wants to test the mystery of this seawater. We shouldn't meddle; just watch."

As they waited quietly, there was no sign of the person who had jumped into the sea.

After a while, the elder sighed, "Let's go."

The girl asked, "Aren't we waiting anymore?"

"No need. It's been so long and he hasn't surfaced. Even immortals find it hard to save anyone in this situation. He's likely already dead down there." If the person had come up sooner, there might have been a chance to live. At worst, his foundation might have been damaged and his cultivation declined, but given enough time, he is certainly doomed.

Half a tea's worth… Even a Sun Blaze might not last half a tea's worth, let alone a young Constellation cultivator.

The girl followed behind the elder, looking back every few steps with a face full of regret, her little brain unable to understand why, despite reaching the Constellation stage, someone would be so unwilling to see sense.

Beneath the All Phenomena Ocean, Lu Ye's body continued to sink.

He observed as a dense gray mist ignited in large patches within the Talent Tree, violently consuming the just-replenished fuel reserves.

This undoubtedly indicated that too many impurities or harmful elements were flooding into his body. The key was that he didn't actively absorb the surrounding seawater's energy.

He didn't initiate it, yet the terrifying energy contained in the surrounding seawater drilled into him like leeches smelling blood.

He finally understood why no one dared to venture into the All Phenomena Ocean lightly.

In this place, whether you want it or not, the energy from the seawater will flood into your body, and it is far more efficient than any cultivation method.

This easily causes the energy within a cultivator to become full, then bloated, ultimately leading to an inevitable explosion and death.

Along with the inflowing seawater energy were vast amounts of impurities…

These impurities are harmful to cultivators, and while there might be an opportunity to dispel them later, it would undoubtedly require a great cost. If they cannot be dispelled, one's foundation would be damaged.

Activating spirit force to protect oneself cannot fully isolate these impurities, and even with the powers of a treasured artifact, it's challenging to counteract them. Thus, even if someone ventures into the All Phenomena Ocean, they certainly cannot stay for long.

With the Talent Tree as his backup, Lu Ye wasn't worried about his safety, but the key issue was that such a situation severely consumed the fuel of the Talent Tree.

This situation was somewhat reminiscent of when he delved deep into the Blood River in the Blood Refinement World to cultivate, yet incomparable in the way this All Phenomena Ocean is perilously much more dangerous.

Perhaps once he no longer has to worry about the fuel for the Talent Tree in the future, he could come here to cultivate, because the efficiency is tremendously high. But for now, that is not possible. Expending the Talent Tree's fuel here would affect his future cultivation.

His body stopped sinking further, as continuing would take him out through the bottom of the All Phenomena Ocean eventually, but that would require much more time than his current fuel reserves could support.

Looking up, there was only a faint light above, while below was deep darkness.

Just as Lu Ye was about to swim up, he suddenly sensed something quickly brushing past him.

He was startled and reached for his waist.

His hand grasped nothing but air, reminding him that the Boulder Mountain Saber was still with the All Phenomena Merchants Guild.

His Mental Consciousness extended, but it could only reach three inches away from his body due to the seawater's strong suppression of it.

Without a saber in hand and with his Mental Consciousness constrained, Lu Ye had no idea what had just swum past him. Without hesitation, he activated his spirit force and darted upwards while staying vigilant in all directions.

As soon as he started moving, Lu Ye felt an unusual current beside him, and with the faint light, he saw a small object swiftly dart by.

Without the slightest hesitation, he punched in that direction, feeling the sensation of something bursting apart under his strike. He grabbed onto whatever he could and continued upwards.

Moments later, he returned to the previous reef island, fixatedly staring at what he had brought back from the sea, dumbfounded.

In the All Phenomena Ocean… there are actually fish!
