On all four sides of this world are oceans.

The ocean is a terrifying and awe-inspiring place, and there have been countless stories and legends about it since ancient times.

It's so vast and dangerous that it's rarely visited.

Xu Jing continued to go deeper, and after half a day, he finally chose a barren island and fell.

It is a large island that is open on all sides, and it is very desolate as far as the eye can see, and there are not even a few trees.

"System."

After Xu Jing landed on the ground in the center of the island, he summoned the system.

A familiar interface appears, and he looks at Mission 3.

After the last promotion to 9999, he first restored the monks of the Great Power Temple, extended the life of the emperor, and bred a large number of tree people and tree demons, and finally dug up a demon core in order to transfer cause and effect.

Although he seems to be unhindered at present, in fact, he has lost more than 1,300 years of cultivation, and the converted cost source point is more than 13,000 yuan.

But it's all worth it, he got the exercises in exchange, gained merit, and accumulated the power of faith for nearly half a year, and soon, these power of faith will be transformed into a real source, making his strength skyrocket.

Xu Jing glanced at the remaining 40,010 points of origin, and without hesitation, he chose to use all of them to improve his cultivation.

The 10,000-year upper limit is just the standard given by the system according to the rules of this world, but there is no provision that it cannot be further improved.

As a large amount of origin turned into pure demonic power and integrated into his body, Xu Jing involuntarily recovered his body and turned into a banyan tree and took root on the island.

Soon, he was restored to his cultivation in 9999, and the huge body occupied almost half of the island, the canopy towered into the clouds, and tens of thousands of aerial roots fell from all over the canopy to the ground, fluttering gently.

Thundered~!

In the next moment, the sky suddenly flashed and thundered, and the rolling dark clouds quickly converged, and within a radius of dozens of miles, it became dark in the blink of an eye.

The clouds grew thicker and thicker, and the calm waves of the sea rose and fell with the wind raging.

Wow~!

The torrential rain poured down, like thousands of arrows, and pierced down fiercely.

Xu Jing stood still, in the midst of the storm, the cultivation that had reached 10,000 years continued to rise ferociously like a rocket, and the emerald green of his body flowed, and patches of light spread out, causing the heavy rain to pour back and the waves to subside.

Bang!

It seemed that his provocative response angered the heavens, and in the depths of the sea, the storm rose again, sweeping towards the island with a huge tsunami that stretched for hundreds of miles.

At the same time, the thunderstorm in the sky was finally brewing, and the dark clouds that covered the sky suddenly pressed down, enveloping Xu Jing's canopy.

Boom Boom Boom Boom ......

In an instant, countless lightning bolts rained down overwhelmingly, like a doomsday disaster.

Click! Click! ……

Xu Jing's crown branches exploded and broke one by one, falling from the clouds, but he breathed a long sigh of relief in his heart.

"Merit."

A pair of eyes sprouted from the trunk of the tree, shooting out two brilliant green rays and looking into the depths of the clouds.

There, in addition to the thunder, there was also a faint layer of golden light that appeared, enveloping his body, and every time lightning fell, after penetrating the golden light, it would change from thick to thin, and its power was greatly reduced.

And in just a moment, Xu Jing's cultivation has reached the level of more than 12,000 years, and the 40,000 points of origin energy consumption have been consumed.

But this is not the end, as his own origin point is used up, a massive amount of faith power is transformed into origin energy through the system, which appears in his body out of thin air and easily integrates into his body.

His whole body shone with endless green light, and the canopy of the tree expanded further, and the trunk grew thicker and taller, and the roots of the tree dug deep into the ground like dragons, piercing the bottom of the sea.

The branches that had been severed by lightning grew and recovered in the blink of an eye in the process of strengthening the source energy, and even became thicker.

The thunder fell one after another, and it seemed that it would never stop.

But Xu Jing let the wind and rain blow, the waves crashed, and the thunder slashed, but he was always silent.

"This time it seems to be stable."

Seeing that the number of years representing cultivation on the system interface was still beating rapidly, and he felt the more and more majestic demonic power cultivation in his body, a big stone completely fell in his heart.

Call~!

At this moment, a strange sharp wind blew, as if there was an invisible hand, plucking the rules.

The dark clouds in the sky slowly swirled, and the color became heavier and heavier, forming a huge vortex.

Rumble~!

Patches of flame emerged from the vortex, and then as if the canopy had collapsed, large chunks fell, sticking to the canopy and blazing.

Skyfire.

Xu Jing's eyes showed a look of clarity on the trunk, from the Kunlun sect and the classics he had excavated himself, he had already had a comprehensive understanding of the process of the Heavenly Tribulation.

At this time, the origin energy in his body finally gradually dissipated, and the intensification reached the end.

"Sixteen thousand years of cultivation."

When he saw the detailed information on the system interface, he couldn't help but feel amazed, the power of faith was enough to increase his cultivation for nearly four thousand years.

And his body at this moment is twice as large as it was at the beginning, and the island where he is rooted can't bear his body, and it keeps cracking and collapsing under the surface of the sea.

Xu Jing seemed to have woken up from his slumber, and his thick trunk shook violently.

Bang.

A pillar of light erupted around him, and everywhere he went, whether it was lightning or heavenly fire, all of them were annihilated and disappeared, and finally the entire heavy dark cloud that shrouded hundreds of miles was blasted open by him to a huge hole.

"It's time to finish."

The countless aerial roots hanging from his canopy flew up like roaring dragons, stabbing into the cloud storm that enveloped the canopy.

Rumble~!

At this moment, Xu Jing resolutely burst out most of the demonic power in his body, and over the entire island, a sun the size of the canopy rose up.

Then a dazzling bright light shone in all directions, the heavens and the earth roared, and a huge mushroom cloud tumbled up, soaring into the sky.

The earth trembled, and the sea water centered on the island rushed madly in all directions, forming a wall of waves up to 100 meters high.

The clouds in the sky could no longer be maintained under the strong impact, and they collapsed in pieces.

Bite~!

A crisp reminder suddenly sounded in Xu Jing's mind, he opened the system, looked at the interface, and sure enough, task 3 had become completed.

He shook the trunk of the tree, reverted to his human form, and floated above the sea.

At this time, the sky was full of glow, and the sound of bells and cranes was bursting, and a white pillar of light slowly fell from the sky and shrouded him.

What makes people can't take their eyes off is that this pillar of light also carries a nine-sided emerald green crystal, and the surface of the crystal is densely patterned, which looks mysterious and abnormal.
