Your life is the river, my life is the sea.

Chen Xia's eyes lit up.

This "Ignite Blood Extinguish Soul Method" is truly perfect for him.

Youth kills the young, the young kill the middle-aged, and the middle-aged kill the elderly.

It aligns perfectly with his current situation.

The exchange of a hundred years of lifespan for eighty years of another person's is incredibly enticing to Chen Xia.

Although it seems like a loss.

But Chen Xia is engaged in a risk-free transaction. Not to mention exchanging a hundred years for eighty years, even exchanging a thousand years for eighty years is no problem. The key point is an extended lifespan.

As Chen Xia continued reading the introduction, his joyful expression suddenly turned into a frown.

The "Ignite Blood Extinguish Soul Method" is an ancient and unfinished technique. The reason for its incompleteness is quite simple: the creator exchanged their own life and perished.

It's truly a tragic tale.

So, currently, this technique cannot exchange a hundred years for eighty years; it can only exchange a hundred years for twenty years, and it can't even exchange the lifespan of an old man.

The explanation in the text is straightforward.

The Grand Dao of the various realms does not allow it.

In other words, this "Ignite Blood Extinguish Soul Method" cannot be used to kill others, only oneself.

It's like when you're in a fight with someone, and you agree to take turns attacking. It may not seem entirely fair, but it's not unreasonable either.

And then, when you stab the person's arm with a knife and wait for your turn to be attacked, they suddenly pull out a gun from their waist.

...

For other cultivators, this "Ignite Blood Extinguish Soul Method" is nothing more than a worthless technique.

Purely a method of self-destruction.

Fortunately, Chen Xia is not an ordinary cultivator.

For him, even if he exchanges a hundred years of lifespan for twenty years, it's still profitable. However, he now sees another limitation.

This "Ignite Blood Extinguish Soul Method" has a cooldown time. After one exchange, he has to wait five years before he can exchange again.

This can no longer be described as worthless; it's absolute crap.

The divine powers have provided a rough explanation.

Cultivators are part of the cycle of the qi and fortune of heaven and earth. The more powerful an existence, the greater their position within the cycle.

Exchanging a hundred years for twenty years may seem highly unfair and utterly useless.

But if you look at it from a different perspective.

If an Infant Transformation stage cultivator exchanges a hundred years of their lifespan for twenty years of a Great Emperor-level existence, wouldn't that be amazing?

If ten thousand Infant Transformation stage cultivators all practice this "Ignite Blood Extinguish Soul Method," wouldn't they be able to directly exchange the lives of two or three Great Emperors?

At that time, everyone would stop cultivation and simply compete for the number of people on their side.

The key is unity, which equals strength.

However, the will of heaven and earth would definitely not allow such a situation to occur, so these two limitations were implemented.

First, it is impossible to exchange the lifespan of an old person.

Second, there is a five-year cooldown period.

These two limitations completely restrict the potential of the "Ignite Blood Extinguish Soul Method" in exchanging lives, to the point that it holds no attraction for ordinary cultivators.

Even the creator exchanged their own life and perished, leaving behind only this half-formed technique in the world.

Chen Xia was also conflicted and asked the Book Spirit, "Can I see a few other techniques that consume lifespan?"

The Book Spirit nodded and casually waved its hand, causing several techniques to float above Chen Xia's head, transmitting their information one by one.

The process was swift, and before long, Chen Xia fully understood. However, this only furrowed his brow even more.

The other techniques that burn lifespan are unremarkable, mediocre at best, relying on sacrificing lifespan to enhance combat power.

But the increase was not much, at most only half, not even reaching a doubling, and there were residual effects on the body when used, causing the burning of life essence.

This is unacceptable, quite unacceptable.

If it only burned life span, that would be fine. After all, what Chen Xia was doing was a costless transaction. Consuming a few hundred or even a thousand years of lifespan was inconsequential as long as it had an effect.

But burning life essence was out of the question.

It's like when you go to the river to catch crabs. Once you catch them, you can sell them and make a stable profit. But then, when you reach out to grab a crab, you get bitten by a snake passing by.

The additional cost is simply too great.

Chen Xia really didn't want that. After careful consideration, he decided to choose the "Ignite Blood Extinguish Soul Method." Even if he couldn't directly exchange someone's life for his own at the moment, he could continue to upgrade the technique.

As long as he completes the "Ignite Blood Extinguish Soul Method" later, even if he exchanges a thousand years for five hundred years, Chen Xia would still come out ahead.

With the technique in hand, Chen Xia leisurely returned to his own cave dwelling. He had already decided whose life he would exchange first.

It's you!

------------

At the far end of the sword.

The Old Fisherman had already received the news, his brows slightly furrowed, his expression filled with doubt.

"Burning life span divine ability, why would he choose such a technique? This is not a good thing for cultivators. Could it be...?"

The black-robed figure below reported, shaking the empty hood on his robe. "According to the Book Spirit, he has chosen the ancient divine ability, 'Ignite Blood Extinguish Soul Method,' which is still incomplete."

The Old Fisherman's brows furrowed deeper, his hands clasped behind his back, slightly tightening.

As someone in a high position in the Azure Sky Sword Sea, he naturally understood the peculiar nature of the "Ignite Blood Extinguish Soul Method."

He was well aware that it was a life-for-life divine ability, with many restrictions, and even the creator himself exchanged his life and died.

This divine ability was simply worthless, nothing more than a stockpile in the Heavenly Tower.

He never expected that someone would actually choose it, and it was Chen Xia of all people.

"Go back. This matter must not be leaked. If anyone inquires, say that he randomly chose a grand Dao technique," the Old Fisherman pondered.

"Understood." The black-robed figure nodded under the empty hood, and in a flicker, disappeared from the hall.

The Old Fisherman's expression grew increasingly heavy as he paced back and forth, constantly speculating in his mind.

Could it be that Chen Xia's Dao Heart had truly suffered immense damage, to the extent that he chose this twisted path?

It shouldn't be. He only lost a trace of divine consciousness in the small world, nothing that would make him so distraught.

He was the successor of the Great Emperor, with boundless prospects. Even if he didn't become a Great Emperor, as long as he reached the realm of a Saint, he could forcefully descend to the lower realms and directly slaughter that realm.

How could he possibly take such a crooked path just because of such a trivial matter? It shouldn't happen, really shouldn't.

The Old Fisherman's expression became serious, his brows tightly furrowed, overflowing with worry.

There were many successors of Great Emperors in the world, but there weren't many like Chen Xia, pure human cultivators.

The rise or fall of other Great Emperor successors was inconsequential.

But Chen Xia had to rise in the upcoming grand era, not to become a Great Emperor, but at least to become a quasi-Saint.

Before he reached that level, there mustn't be any accidents!

Old Fisherman's eyes flickered with a gleam as he decided to bring along some extraordinary treasures and go comfort his precious disciple, who had come a long way.

Meanwhile, his "precious disciple" was sitting in the cave, studying the Ignite Blood Extinguish Soul Method.

This divine technique was simple and easy to understand, even a Foundation Establishment cultivator could use it; it all depended on whether you were willing to use it.

It could be considered a supreme suicidal move.

Chen Xia sighed in relief, grateful that he was involved in a risk-free business.

His divine sense stirred, and in his mind, a knife suddenly appeared, lying across a long river of time.

This river represented the length of Old Fisherman's lifespan, stretching for thousands of feet.

With determination in his heart, Chen Xia forcefully sliced off half a meter of the river, effectively shaving off twenty years.

Unbeknownst to gods and ghosts.

Now it was Chen Xia's turn to make the cut.

The scene changed for the knife in his mind.

And thus, a vast and boundless ocean of time emerged...
