For Returning Void Cultivators, the most challenging step to advance to Integration is actually comprehending the Power of Domain.

From Law, to Domain.

During this period, it is not an absolute measure of strength and weakness.

For example, some cultivators might comprehend a certain Law to the Realm of Perfection, yet still delay in comprehending Domain.

While others might only comprehend a Law to Great Success, but can already grasp Domain.

The difference here is actually a matter of influence and coverage!

The Power of Law mainly influences oneself.

It can also be applied to a single target.

For instance, Lin Chen’s Time Law can ripen Spiritual Medicine, or even accelerate the growth of living beings, directly depriving them of lifespan.

But Lin Chen can only apply the Power of Time to a single target.

Lin Chen attaches the Time Law onto his Demon-slaying Blade, and with one slash, he can cut away three thousand years of the enemy’s lifespan.

With a few more slashes, even if Lin Chen does not kill them, they would die from lifespan deprivation.

In contrast, Domain is imposing a field within a specific range around oneself.

Any enemy entering this range will have their lifespan deprived, without needing other mediums to apply the Power of Law.

Besides this, the Time Law is even more mysterious.

Within the realm of the Time Law, all enemies’ perception of time greatly decreases.

In fact, they cannot even perceive the passage of time.

Whether human or any living being, once they lose perception of time, they are like lambs waiting to be slaughtered.

Interestingly, Lin Chen mastered the Time Domain early on.

Or in other words, the initial template of the Time bestowed by Candle Dragon carried the capability of Time Domain.

For instance, Lin Chen’s Bullet Time accelerated the perception speed around him countless times, which was already close to the power of Domain.

Later on, Lin Chen could slow down the flow of time within a hundred yards radius, gaining an advantage in battle.

This is also a form of Time Domain.

Afterwards, Lin Chen could even reverse his state by three seconds, equivalent to a life-saving amulet.

And after decades passed, Lin Chen’s comprehension of the Time Law and Domain was vastly different from before.

Maintaining Bullet Time for a quarter of an hour is no longer difficult for Lin Chen.

During this quarter-hour, Lin Chen effectively possesses the strongest combat means.

He can virtually foresee and respond optimally to all the opponents’ Technique and Divine Techniques attacks.

With the Time Blade Technique, Lin Chen can slash away up to three thousand years of an enemy’s lifespan with a single strike.

Even an Integration Cultivator cannot withstand a few strikes from Lin Chen.

As for Time Reversal, Lin Chen can reverse his own state up to seven seconds prior, further enhancing his survival ability.

Regarding Time Domain, Lin Chen is just starting to grasp it.

At most, he can slow down the flow of time within a hundred yards radius to three times slower.

Even so, it proves useful in combat scenarios.

"The Power of Domain is the most challenging for Returning Void Cultivators to advance to Integration... yet I achieved it early."

"The Integration Pill and Seventh Tier Soul-Protecting Pill have also been prepared for refinement; all that remains is to refine them to perfect quality."

"As for Integration Stage Cultivation Technique... the Celestial Derivation Pearl is still undergoing inference, it should take another two or three years to infer."

Lin Chen thought silently, not rushing himself.

In this Jiang Country Celestial Ruins, he plans to stay for nearly twenty more years.

These twenty years are enough for Lin Chen to advance several great strides in cultivation.

"Then, the next goal is clear."

"Crossing the Tribulation, achieving Integration Stage!"

Lin Chen murmured to himself.

...

In the following few months, Lin Chen focused more on refining the Integration Pill and the Soul-Protecting Pill.

On the Blue Star, thousands of Spirit Medicine Flowers were planted for refining the Integration Pill.

Through Lin Chen’s Time Law, an average of a thousand Spirit Medicine Flowers matured within a month.

Afterwards, Lin Chen used instruments to refine the Pills.

A year later, the Perfect Soul Protection Pill was successfully refined.

Six months later, the Perfect Integration Pill was completed.

At this moment, Lin Chen only lacks the final Integration Stage Cultivation Technique.

The Celestial Derivation Pearl was still undergoing inference.

The inference took a year and a half in total.

The Evergreen Technique Integration Chapter was successfully deduced.

Lin Chen spent three months thoroughly researching the Integration Chapter.

At this point, only the final tribulation crossing remained.

Everything is ready, only the east wind is lacking.

...

New Era, spring of 3115.

On an auspicious day, everything is in favor.

This is Lin Chen’s one hundred and tenth year of cultivation.

In just over a century, Lin Chen advanced from the Qi Refining Stage all the way to Returning Void Perfection.

After achieving Divine Soul Perfection, Lin Chen only needs to overcome this final Integration Thunder Tribulation.

...

Kyoto of Great Xia, behind the mountains of the military region.

An area of three hundred miles is under military jurisdiction and surveillance again.

Tens of thousands of martial artists from the military protected the entire mountain.

Lin Chen returned to the mountain, preparing to cross the tribulation.

This wasn’t Lin Chen’s first tribulation crossing; he had already done it many times.

The difference this time is that it’s a breakthrough to the Integration Stage.

It will be the most difficult and dangerous tribulation yet.

Because among the Human Race’s strongest, Yue.

Is only equivalent to Martial Saint Perfection, akin to Integration Cultivator.

Should he encounter danger, Yue won’t be fully confident in saving Lin Chen.

But Lin Chen has little worry in his heart.

Although the risk is greater, Lin Chen’s preparation is sufficient.

He holds fifteen thousand drops of Spirit Realm Jade Dew and nearly three thousand drops of the Water of the World.

With so many life-saving items, passing the Integration Thunder Tribulation is not difficult.

Moreover, when crossing the tribulation, Lin Chen also aims to advance to an even higher realm in the Martial Path.

He was stuck at the entrance to the Muscle Refining Realm for years, still just a step away from Minor Achievement.

Now, Lin Chen wants to test how much his strength can improve after crossing the thunder tribulation.

...

Moments later, Lin Chen adjusted his state to the best.

The whole body slowly levitated toward the sky.

As the Integration Pill entered his stomach, Lin Chen adjusted his aura to peak condition, constantly surging out True Essence.

Communicating with the heavens.

High above, thunder clouds began to gather, with faint sounds of thunder.

After tens of breaths, the thunder clouds finally showed signs of falling.

Seeing this, Lin Chen did not hesitate and directly swallowed the Soul-Protecting Pill.

All preparations were complete, awaiting the descent of the thunder tribulation.

The ten breaths quickly passed, and the first thunder tribulation rolled down from the sky.

Lin Chen raised his eyes, facing the thunder tribulation directly.

The lightning struck his body, its power and destructiveness stronger than the Returning Void’s Nine-Nine Thunder Tribulation.

However, Lin Chen today is not the same as he was twenty years ago.

The difference between the Skin Refining Realm and Muscle Refining Realm is significant.

You could see Lin Chen standing firm, enduring nine whole thunder tribulations.

At the same time, the pure energy of the thunder tribulation continually baptized Lin Chen’s flesh body.

"Whew, One-Nine Thunder Tribulation successfully crossed..."

Lin Chen took a deep breath, feeling his flesh body rapidly absorbing the energy of the thunder tribulation.

The Qi and Blood Value became more abundant.

"Huh..."

Lin Chen was slightly surprised; his Martial Path bottleneck, which hadn’t broken in three years, actually broke through from the impact of these nine thunder tribulations.

Muscle Refining Realm, achieved Minor Achievement!

And immediately following, the Two-Nine Thunder Tribulation is about to fall.
