Slaying a Hundred Beasts, Ouroboros!

Deep in the sea.

Boom!

As Lin An wielded the Condemnation, he directly slew one of the sealed Sin Beast without any hindrance.

Lin An was not surprised by this. Although this Sin Beast was also at the True Source Realm, even if it hadn't been sealed, with his combat power increased by tens of thousands of times, he could easily kill it instantly.

After slaying the Sin Beast, Lin An waved his hand and used alchemy and weapon-forging techniques to extract the Sin Beast's Origin Power.

In addition, Lin An also collected valuable parts from the Sin Beast. These were Eternal Rank materials, which could be used not only for alchemy and weapon crafting but also for creating puppets.

Finally, Lin An put the corpse of the Sin Beast into his Spirit-Devouring Ring.

Although the Spirit-Devouring Ring is only at the level of Heaven and Earth Supreme Treasure, it can still barely refine the corpse of Sin Beast in the Eternal Realm, only at an extremely slow speed.

"After that, I'll try to see if I can upgrade the Spirit-Devouring Ring to a higher level. After the Heaven and Earth Supreme Treasure, it seems the next level is the Eternal Spirit Treasure."

As Lin An pondered this, his gaze also fell upon another Eternal Realm Sin Beast that had been sealed away.

Condemnation swung again, easily slaying him.

For the rest of the time, Lin An was either slaying Sin Beast or on his way to slay Sin Beast.

These Eternal Realm Sin Beast were mostly at the True Source Realm, and since they were sealed, they were naturally destined to be killed by him.

However, there were also three Sin Beast that had reached the Primordial Source Realm, so Lin An didn't rush to attack them and planned to save them for last.

In the blink of an eye, half a month had passed. Of the more than one hundred Sin Beast, he had killed most of them, but the three Sin Beast at the Primordial Source Realm were still alive.

"First, cultivate and refine these hundreds of portions of origin. When that happens, your strength will increase greatly, and then you can slay these three Primordial Source Realm Sin Beast."

Thinking it over, Lin An left the sea area and, on a whim, arrived at the city he had visited before, only to find that the stone tower had disappeared.

"I was hoping to take this opportunity to absorb some Origin Power, but it seems that won't work."

Lin An shook his head, sat cross-legged in the center of the city, and set up a series of restrictions around the city.

Buzzing...

As the Auxiliary Cultivation Lotus Platform unfolds, a time flow rate of 2,500 times is activated.

Lin An also took out a portion of the source and began refining it as he circulated his cultivation technique.

A large amount of Origin Power surged into his body and eventually merged into his own primal essence.

The process proceeded without any obstacles.

Upon reaching the Eternal Realm, one essentially becomes a world unto oneself. Although their origins differ, they ultimately converge.

They can devour and refine each other without any restrictions.

Unlike when you were at a lower level, refining the power of others wouldn't lead to an unstable foundation or even a backlash.

While Lin An appears to be refining the essence of those Sin Beast, it can also be seen as Lin An's great world devouring the worlds formed by those Sin Beast.

Cultivation knows no time; it wasn't until a hundred years later that Lin An Anfang completely refined a portion of the Origin Power.

"As expected of the origin of the True Source Realm, it takes hundreds of years to refine even a single portion."

"I currently possess over a hundred portions of the Origin Essence. If I were to refine them all, it would take approximately ten thousand years."

Lin An sighed inwardly, realizing that the higher one's cultivation level, the longer it takes to advance to the next level.

Even with sufficient cultivation resources, he would need tens of thousands of years to cultivate.

Of course, this is only true for him. If it were other True Source Realm experts, they could only touch the opportunity for a breakthrough after refining at most ten or so portions of the Origin.

Fortunately, he had a time acceleration of more than two thousand times, so even if he cultivated for ten thousand years, only four years would have passed in the outside world.

Even if he reaches his limit later and spends another ten thousand years accumulating time to break through to the Primordial Source Realm, only eight years will have passed in the outside world.

Lin An could easily accept this amount of time.

Lin An then stopped thinking about it and continued refining these origins.

As he refined each elemental source, his aura rapidly increased.

A thousand years later, he had refined ten portions of the source, and he estimated that if there were an experience bar, he would have improved by about 10%.

Five thousand years later, he refined fifty portions of the origin, and the aura emanating from him had undergone a tremendous change.

At the same time, a phantom of a world spontaneously evolved around him, as if a world had truly been born because of his existence.

Lin An didn't care about this. He had no intention of evolving a world. This phantom was simply constructed by the Origin Power his own origin that he inadvertently released after his origin became powerful.

Ten thousand years later, when Lin An refined the last bit of origin, his aura had reached its limit.

His own essence is now a hundred times stronger than before. If he wanted, he could create the world in an instant and evolve a true world.

"It's still not quite there."

Lin An opened his eyes, concealed his aura, and immediately all the strange phenomena around him disappeared.

He is still at the True Source Realm, although he has reached his limit, he has only barely touched the threshold of breaking through to the Primordial Source Realm.

He still needs a push to help him break through to the Primordial Source Realm.

His gaze fell upon the three remaining sealed Sin Beast deep within the sea.

All three of these Sin Beast were at the Primordial Source Realm.

If he could kill these three Sin Beast and seize their essence, it would surely help him break through to the Primordial Source Realm.

"However, these three Sin Beast may not be so easy to kill."

Lin An thought to himself, the stronger he was, the more he could feel the power of the Primordial Source Realm.

Although he is quite strong now, he would still be certain to die if he faced Primordial Source Realm expert.

Fortunately, all three Sin Beast have been sealed away, and their strength is far less than before.

Lin An immediately took a step forward, his figure once again appearing beneath the sea, his gaze falling upon one of the Sin Beast at the Primordial Source Realm.

It was an Ouroboros, and although it was sealed away, its body was so enormous that it could not be measured by ordinary standards.

Its body resembled a giant, dark golden ring without beginning or end, and around it, countless phantom images of worlds appeared.

The serpent's head was ferocious and ancient, covered with dark golden scales, each scale engraved with the Dao patterns of decay, constantly shifting between reality and illusion. If one stared at it for too long, it could even cause one's soul to decay.

Its eyes had no pupils, only two black vortexes, like black holes that devoured everything, reflecting countless scenes of world destruction.

The exposed fangs are formed from fragments of broken time; if one were to be bitten by one, one would be completely erased from the past, future, and present.

As if sensing Lin An's arrival, the Ouroboros's eyes, as black as holes, fell upon Lin An.

At the same time, a voice powerful enough to annihilate countless lives also rang out.

"Human Race, do you think you can kill me?"
