As it turns out, under the already perfect Three Demon Pill System, upgrading to the Four Demon Pill System is extremely difficult.

It's equivalent to creating a brand-new system.

No less challenging than installing an engine on a bicycle.

There are too many adjustments needed and too many problems occur. It's like playing whack-a-mole, to the point where Wang Wu almost had a mental breakdown.

At this moment, however, he felt grateful for the Evil Wind Bone Plague because he had endured even more desperate and dark times, so retreating now was not an option.

But the condensation of the fourth demon pill still made little progress, and Wang Wu spent a whole year struggling.

During this year, all the vitality he acquired was used to run the large model of the Four Demon Pill System.

Otherwise, by now he would have already upgraded the three demon pills, with his combined strength reaching the Fifth Grade, equivalent to a Little Demon King capable of ruling a mountain.

Of course, it wouldn't be right to say there were no gains; at least Wang Wu's theory on the Four Demon Pill System had become nearly perfect.

Because this was truly a path he had forged himself, with no prior experience to draw from.

He continuously made mistakes, distilled his ideas, and improved, finally establishing the positioning of the fourth demon pill as a serving, highly coordinated, and strongly supportive super demon pill that could act as both a warehouse and a dam, something useful for both inflation and deflation, a brick to move wherever needed!

With a clear position, the next step was to run data and models.

Every bit of vitality he acquired was thrown into it without reservation.

He must especially thank his savior, the bees, truly benevolent benefactors!

Selflessly and unconditionally providing a massive amount of vitality without complaint.

The daily vitality provided was equivalent to 1.5 Ninth-Grade Ginseng Vitality Pills, a luxury even the middle class of the West Wilderness Demon Race couldn't afford.

After all, Vitality Pills were considered hard currency in the West Wilderness.

Month after month, a year went by, and Wang Wu turned nineteen, then twenty years old.

For the sake of the Four Demon Pill System, he had painfully spent nearly four years.

During these four years, his own innate system's cultivation made no progress, and even his practice of the Ice and Fire Dual Spirit Roots was significantly delayed, reaching only 25/50.

But as they say, all efforts bear fruit; the lack of gains is only due to insufficient effort.

After nearly four years of torment, the large model of the Four Demon Pill System was finally illuminated for the first time.

This so-called illumination meant that the Qi and Blood Circulation could successfully complete a full cycle, with speed not less than 60% of the normal value and consumption not exceeding double.

Overall, it was still a bloated and somewhat unreasonable system, but having it operate was itself a great victory.

At that moment, Wang Wu was so happy he wanted to cry out loud, dance on the spot.

Although it was just a small victory at the start, it was of great significance.

Next up was optimization.

It's relatively simple, with a bunch of optimization packages updated daily, from version 1.0 to 1.009, then to 1.1, updates and firepower are unlimited.

Unknowingly, he turned twenty-one, and when he counted the time, it had been nearly sixteen years since Lu Wuchen imposed the great blockade on him, and there was little time left for Lu Wuchen.

What a pity, not being able to see Old Deng's chaotic and angry expression firsthand.

I wonder how Ah Qing is doing?

And will Old Niu and the Little Wild Boar be caught in the crossfire?

Additionally, as for the Centipede General who could fly and escape, even if he didn't die this time, he'd at least shed a layer of skin.

But then again, that one is the ancestor of the sly survival tactics.

The Centipede Ridge region is next to the Black Forest, and Grandpa Tree is not to be trifled with. Especially since the Spirit Pill industry chain in the Centipede Ridge pit has reached a high level, benefiting many Human Race Cultivators. Would Lu Wuchen really disrupt this large operation?

He's not that unreliable.

But then again, maybe he is Lu "Very Reliable."

If he has time for random thoughts, that means the pressure is greatly reduced, and success is within reach.

Indeed, after four years of building the large model and a year of optimization, the Four Demon Pill System is steadily progressing forward, and now the Qi and blood circulation speed per cycle has reached 81% of the normal value, with consumption only 52% more than before, which is quite commendable.

What can be confirmed is that once the fourth demon pill is formally condensed in the future, this efficiency will increase significantly again.

Wang Wu doesn't have high demands; as long as the speed of the Qi and blood circulation can reach 90% of the normal value, it will be a great victory.

Therefore, he is still willing to spend precious time polishing and optimizing.

Even if it means continuing to delay the practice of the Ice and Fire Spirit Root, he doesn't mind.

It's worth mentioning that in the past five years, he has injected 500,000 points of Spiritual Qi into his Inheritance Soul Jade version attribute bar, consuming exactly one hundred Eighth-Grade Spiritual Qi Practice Pills in the process.

It pained him quite a bit.

Fortunately, after five long years, this Inheritance Soul Jade version attribute bar finally revealed a health bar.

"The Inheritance Soul Jade is now stable, requiring an additional 500,000 points of Spiritual Qi or vitality to complete its final restoration."

"You can also choose to stop injecting, but you will not receive the complete inheritance."

"It has been detected that you are currently undergoing a cultivation transformation. Would you like the Inheritance Soul Jade to assist in reconstructing your fourth Demon Pill? Friendly reminder, this process may require consuming more Spiritual Qi or Vitality."

——

"Huh?"

Wang Wu was taken aback, then overjoyed. Indeed, the Spiritual Qi spent was not in vain; the Inheritance Soul Jade + attribute bar truly added wings to a tiger.

At this moment, he of course chose to intervene.

Then, there was a long silence, no movement whatsoever.

At one point, he almost thought the thing had crashed.

It wasn't until a dozen minutes later that a peculiar wave of power finally emerged, exactly the operational model of the four Demon Pill system Wang Wu had been painstakingly optimizing.

For a moment, Wang Wu had a flash of inspiration and captured the key points, immediately making slight adjustments and changes. After completion, he performed the Inner Breathing Technique, mobilizing Qi and Blood Circulation. Abundant vitality flowed into the central heart, then into the three Demon Pills, and then returned to the convergence point of the fourth Demon Pill, before finally completing the entire Circulation of Heaven.

The operational speed of the entire Qi Blood Circulation had a noticeable increase, and even the consumption decreased by five percent.

When the final results emerged, Wang Wu was genuinely delighted because this modification increased the operational speed of the Qi Blood Circulation to 85% of the normal value. If the fourth Demon Pill were successfully condensed, it would undoubtedly reach 90%.

But at this moment, a piece of information floated by.

"The highest operational efficiency of your constructed four Demon Pill system stops at 91.2%. It is recommended to adopt the Five Demon Pill System."

Five Demon Pills?

Wang Wu was stunned. He hadn't really imagined it, never dared to. The four Demon Pill system was already so difficult, let alone the Five Demon Pill System!

Wouldn't it just explode?

But the Inheritance Soul Jade showed no more new information. It's still not smart enough. Thinking back to that DS thing from his hometown, now that was impressive...

But then again, if the Inheritance Soul Jade + attribute bar were truly that impressive, Wang Wu would have eliminated it at the first sign.

An assistant is best always being an assistant. A tool remains a tool. One cannot allow the auxiliary tool to take over; otherwise, how is that different from having a hen crow at dawn?

When you choose to give up your right to take charge, then don't cry or blame the heavens and earth in despair in the future.

Yes, I'm talking about you, who ran out of supplies.

Wang Wu decided to stop injecting Spiritual Qi or Vitality into the Inheritance Soul Jade from today on.

Even though it was recommended by Bear Mother, even though he might not obtain the complete Xiong Pi Demon Emperor bloodline inheritance, he didn't mind.

Certain boundaries that cause a decrease in a sense of security cannot be let go.

However, the Five Demon Pill System?

This truly felt like opening a new window for Wang Wu, who was already quite solid in the theory of the Four Demon Pill System. At the moment, inspiration burst forth endlessly.

Indeed, all the headaches and breakdowns in the Four Demon Pill System were hardly an issue in the Five Demon Pill System because the newly added fifth Demon Pill could completely share the functionality of the fourth Demon Pill.

So it could take on greater pressure, providing stronger, more buffering space.

"Thus, operational speed never was an issue. A single Demon Pill struggles to provide comprehensive support for three Demon Pills, but if two Demon Pills provide logistical support for three Demon Pills, it's much more comfortable."

"Especially since the ones I'm building and condensing are not main Demon Pills!"

In just half an hour, Wang Wu initially completed the construction layout of the Five Demon Pill System, while for the Four Demon Pill System, it took him a full year to reach this step.

Next, Wang Wu set up two Qi and Blood Vitality transfer hubs at his left and right kidneys, as the initial positions of the fourth and fifth Demon Pills.

These two positions were exactly below the first and second Demon Pills.

The extension line of the first Demon Pill and the second Demon Pill intersects at the third Demon Pill.

Then the extension line continues, ultimately reaching the fourth and fifth Demon Pills, forming a structure of an inverted triangle + a regular triangle.

After completing the initial construction, Wang Wu did not perform a comprehensive optimization test and directly operated it, resulting in a delightful surprise as it lit up instantly.

The operational speed easily reached 97% of the normal value, and the critical operational consumption decreased instead of increasing, reducing by 21% compared to the normal value. Truly fascinating.

Indeed, no matter how well-optimized the local details are, it's no match for a superb overall architecture!

Subsequently, Wang Wu didn't bother revising and validating further but officially began condensing and cultivating the fourth and fifth Demon Pills. Since good is simply good, he only needed slight adjustments for any minor flaws during the cultivation of the Demon Pills.

And as he started cultivating, even in less than half a month, the effect was immediate. He could already feel the relaxation and security brought by these two future logistic Demon Pills.

It was just that feeling of driving on the road, glancing at the remaining range, and realizing, oh wow, it can still drive a thousand more kilometers.

In the past, the three Demon Pills only made him stronger, but now this operation was equal to having a large long-range fuel tank + big battery pack.

"No, it must at least be comparable to controlled fusion."

Wang Wu secretly rejoiced in his heart, brimming with pride, sense of security +500!

Indeed, this young master is generous today.
