Chapter 378: Seven-Colored Golden Core, Terrifying Heavenly Tribulation

Not long after, Lu Xun flew away from the capital city and arrived at a deserted mountain on its outskirts.

Immortal cultivators undergo heavenly tribulation, but it is forbidden to do so inside a city.

Even a fifth-boundary heavenly tribulation, if mishandled, can cause massive casualties.

"Right here will do."

Lu Xun looked over the surroundings and felt satisfied with the environment for crossing the tribulation.

He sat cross-legged in the air, waiting for the mysterious pill to form.

This time, he pushed past the fortieth layer in the fourth boundary before finally breaking through.

Reaching such a height, the quality of the mysterious pill will surely be terrifyingly high.

Inside his body.

With the returning heat flow continually arriving, Lu Xun's mysterious pill is rapidly forming.

Soon, within his spirit palace, a mysterious pill the size of a pigeon's egg appeared.

A fifth-boundary mysterious pill at its smallest is about the size of a pigeon's egg.

A slightly larger one can reach the size of a glutinous rice ball or a chicken egg.

After all, it is only the fifth boundary; an immortal cultivator's power cannot be too vast.

With Lu Xun, however, it is completely different.

After the mysterious pill appeared, it seemed to turn into a black hole, with spirit power from within his spirit palace continuously rushing into it.

As these streams of spirit power flowed into the mysterious pill, its size began to increase.

From the size of a pigeon's egg, it grew to that of a glutinous rice ball, then to a chicken egg.

And after the mysterious pill grew to the size of a chicken egg, the spirit power within Lu Xun's spirit palace remained immense.

If one inspected with divine sense, they would feel a vastness like the sea.

It seemed that what had been used before was merely a trifle.

There was no way around it—Lu Xun's spirit power was not only high in quality but also extremely abundant in quantity.

Therefore, the mysterious pill's growth was still ongoing.

But after reaching the size of a chicken egg, the mysterious pill was not merely growing larger.

Its color began to deepen continuously.

From white, it gradually turned white with a hint of yellow, then yellow with a hint of gold, and finally became pure gold.

"Golden Core!"

The golden-colored mysterious pill was no surprise to Lu Xun.

Having broken through so many layers beyond his limit, if he could not yet condense a golden core, that would be contrary to reason.

After the mysterious pill turned golden, its diameter exceeded ten centimeters, larger than a goose egg.

The spirit power within his spirit palace had only been consumed by about half at this point.

With the returning heat flow still arriving, the mysterious pill continued to draw in spirit power without cease.

Its transformation continued as well.

Its size kept increasing, its color deepened further, becoming brilliantly golden, even more dazzling than gold.

It even gave the sensation of divine metal.

After several hours, finally all spirit power was exhausted, and the returning heat flow was also used up.

At that moment, Lu Xun's mysterious pill had fully formed.

"Seven-colored golden core... is this one of a kind?"

Lu Xun murmured softly.

Deep within his spirit palace, a perfectly round golden core hovered, radiating brilliant golden light throughout.

The surface of that golden core glowed with seven-colored misty light, sometimes like intertwining rainbows, sometimes like a flowing galaxy, casting myriad splendid halos in the void, illuminating the entire spirit palace as if in a dreamlike illusion.

Such a golden core is who knows how many times more formidable than an ordinary golden core.

Not only is the mysterious pill one of a kind, its size is likewise astonishing—nearly twenty centimeters in diameter, not much smaller than the monster pill Lu Xun first obtained.

Size alone cannot explain everything.

When Lu Xun first obtained the monster pill, the demonic power within it was that of a seventh-boundary great demon king.

Now, the spirit power within Lu Xun's golden core belongs to the fifth boundary.

Yet the spirit power of the fifth boundary is comparable to the demonic power of the seventh boundary.

This is the benefit Lu Xun gained after surpassing his limits on the immortal path.

This makes Lu Xun unique in every boundary.

"Such thick tribulation clouds... it seems the heavenly tribulation is coming."

Lu Xun opened his eyes, a glint of gold flashing in his pupils.

He raised his head to look at the sky; at some point, the entire heavens had been completely covered by heavy dark clouds.

Those clouds were black to a frightening degree, as if they were about to press down onto the ground.

It gave the feeling of dark clouds pressing down on the city, about to topple it.

Within the cloud layer, blinding lightning flashed intermittently, accompanied by earth-shaking thunder, as if the sky were angrily roaring.

"It's about to begin..."

Lu Xun muttered softly, feeling the growing oppressive pressure in the air.

"Come on!"

He felt no fear.

It is merely a fifth-boundary heavenly tribulation.

"Boom—"

A few minutes later, a blinding bolt of lightning suddenly tore through the sky, carrying the force to destroy heaven and earth, striking straight at Lu Xun's heavenly crown!

"Good timing!"

Lu Xun's eyes flashed with sharp light; he did not dodge or evade, his right fist surging with thick spiritual power as he boldly met it.

At the moment his fist struck the lightning, a deafening explosion burst forth.

"Crackle! Hiss—"

Countless electric snakes scattered and flew about, wildly wandering within a radius of a hundred zhang.

The ground was blasted with scorched pits by the aftershock, plants instantly turned to powder, and the air filled with a pungent burnt smell.

"Boom—"

The second tribulation lightning arrived.

It seemed that Lu Xun's casual shattering of the lightning provoked the tribulation; this bolt was thicker and its power equally astonishing.

"Hah!"

Lu Xun struck again, easily shattering it.

He was not using true qi, but rather infusing his fist with spiritual power—equivalent to the body cultivator's method in immortal cultivation.

Lu Xun was not a body cultivator, but a martial cultivator; his bodily strength was not inferior to that of a body cultivator.

This allowed Lu Xun to temper himself in this way.

Still, there is a difference: body cultivators' use of spiritual power in close combat is more refined, and they have specialized techniques.

"Boom~ boom~ boom~"

Tribulation lightning fell in succession, one after another.

Each one was fiercer than the last.

The number of lightning bolts per strike also increased; it was no longer one at a time, but two or three at once, sometimes even more.

"Sixth strike—should be three more left; is this all the strength you've got? But it's addictive!"

Lu Xun felt it wasn't enough.

In immortal cultivation, the tribulation lightning is numbered by 'nine'.

The Five Realms have nine tribulation lightning bolts, a 'one-nine' heavenly tribulation.

The Six Realms have eighteen tribulation lightning bolts, a 'two-nine' tribulation movement.

Upon reaching the Seven Realms, it becomes twenty-seven tribulation lightning bolts, a 'three-nine' heavenly tribulation.

If it is the Eight Realms, it directly doubles, becoming a 'six-nine' heavenly tribulation.

The Nine Realms are ninety-nine eighty-one tribulation lightning bolts.

Past the Nine Realms comes the Five Declines of Heaven and Man, far more terrifying than the tribulation lightning—by a hundredfold or more.

Lu Xun, being too strong, felt nothing when dealing with the tribulation lightning.

He didn't need any special means; he could shatter each tribulation lightning bolt one by one.

Thus the tempering effect of the tribulation lightning on Lu Xun was greatly reduced.

Finally.

The nine tribulation lightning bolts had completely fallen.

The sky grew quiet.

"None left?"

Lu Xun looked up at the sky.

He sensed something was off.

If it's over, why are the tribulation clouds above growing thicker?

"Boom—"

Just as Lu Xun wondered, a purple bolt of lightning as thick as a water barrel came crashing down.

"Quite the fellow!"

"There's still more!"

"Wasn't it said the Five Realms only have a one-nine tribulation? How did he exceed the limit here."

"Bring it on!"

Although doubtful, Lu Xun welcomed it.

Because he had discovered another use for the tribulation lightning.

After shattering the tribulation lightning, he could use chaotic cells to absorb the surrounding lightning energy, turning some chaotic cells into 'lightning cells'.

Although he currently doesn't know what they're for, the lightning energy itself is valuable; Lu Xun can release and make use of it.

At the same time, it can also temper himself.

Thus the abnormality of the tribulation lightning caused Lu Xun no panic.

The second round of tribulation lightning was larger, and the number falling at once was also greater.

Each time, several bolts would fall.

Lu Xun's surroundings thus became an ocean of lightning.

Tribulation lightning struck down one after another in a frenzy.

"Any more?"

After the second round of nine tribulation lightning ended, the third round came immediately.

"It won't make me undergo a three-nine tribulation, will it?"

Lu Xun speculated.

The Three Nine Heavenly Tribulation, but it is the tribulation for passing the Seventh Realm.

Could it be that the Heavenly Dao judged Lu Xun's combat power to be Seventh Realm, thus making him undergo the Three Nine Heavenly Tribulation?

The third round of tribulation lightning grew ever more terrifying; even Lu Xun couldn't just brush it off lightly.

Not only terrifying, the number of tribulation lightning in this round is extraordinarily huge, with each wave striking ten or more bolts.

If it weren't Lu Xun, a Fifth Realm cultivator would surely perish even if they exhausted all their means.

Of course, if it weren't Lu Xun, there wouldn't be such a fearsome heavenly tribulation.

"Wow, this tribulation is terrifying; which mighty expert is undergoing tribulation?"

"I don't know; this is the twenty-third bolt, Three Nine Heavenly Tribulation, definitely a Seventh Realm expert."

"Has someone else broken through to the Seventh Realm again?"

Lu Xun's tribulation commotion has already startled many people.

In the Capital City, many cultivators, seeing the commotion, came running to watch.

However, since they couldn't see Lu Xun at all at this time, they all regarded this tribulation as a Seventh Realm tribulation.
