Epoch-Making Change

Over the next few days.

Gravity testing became the courtyard's regular attraction.

At first, Ye Guyi would be left disheveled by the intense pressure, sometimes even collapsing onto the metal plate from exhaustion.

But with the effects of large quantities of Blue Jade Pills and Red Jade Pills piling up, the results were astonishing.

Astonishing.

The crushing gravity did not destroy her. Instead, it acted like a forging hammer, relentlessly pounding the soul power within her body.

The energy that had once been rather loose was compressed tightly within her meridians, becoming extraordinarily condensed and increasingly easy to control.

Not only that.

Under such extreme torment, her physique had become even tougher than that of defense-system Soul Ancestors at the same level.

Huo Yuhao thought that if Ye Guyi swung that short sword at someone now, she could probably shatter their bones with a single slap.

A few days later.

Ju Zi produced a rough blueprint and proposed a soul-tool research direction concerning the recovery and storage of soul masters' soul power.

Thus.

Huo Yuhao dragged Xuan Ziwen to the workbench, where they stayed up for several nights in a row.

"Traditional core formations are all designed to unleash power or provide defense."

Holding a charcoal pencil, Huo Yuhao scribbled wildly across the blueprint.

"What if we don't release the soul power? What if we reinforce the formation and lock it inside a fixed metal container?"

Upon hearing that, Xuan Ziwen, dark circles beneath his eyes, froze.

Lock away soul power?

"But energy has an extremely high dissipation rate inside inanimate objects."

"Then we'll use nested internal circulation loops in the sealing formation and reduce the dissipation rate to the lowest possible level."

Huo Yuhao calmly gave his answer.

Xuan Ziwen snatched the blueprint away and bent over the table, beginning a frantic series of calculations.

The facts proved that this idea was feasible.

With the brains of these two combined, there truly was little they could not solve.

Several rare metal plates.

Several storage and sealing matrices that had been restructured and optimized.

Very soon.

The first finished product appeared on the table.

It was a small metal cylinder with a smooth surface and slightly rounded ends.

Since its core function was solely energy storage, its overall production difficulty was unexpectedly low.

Huo Yuhao casually gave it a name.

Milk Bottle.

At first, Xuan Ziwen could not quite understand the meaning of the name.

But when he forcibly poured a stream of his soul power into it, his whole body stiffened.

There was no rejection reaction within the metal cylinder. That stream of soul power was firmly locked inside the core formation.

Then, with a thought from Xuan Ziwen.

The soul power he had just stored actually flowed smoothly back into his body through his palm.

"This..."

The hand holding the Milk Bottle began to tremble violently, and Xuan Ziwen's face flushed red with excitement.

"Epoch-making... This is absolutely an epoch-making creation!"

He shouted incoherently.

Before this, every soul master across the continent had followed one unchanging rule.

Release soul skills.

Consume soul power.

Find a safe place, sit cross-legged, and meditate.

When facing an evenly matched battle, the deciding factor was often not who was stronger, but who had more soul power and who could endure until the end.

But now, the Milk Bottle had appeared.

Imagine a soul master going onto the battlefield with dozens of energy-filled Milk Bottles hanging from their body.

They could throw out soul skills wildly while drinking from Milk Bottles to recover.

That would be a perpetual machine that never had to worry about running out of mana.

Even casually considering such terrifying strategic value made goosebumps rise all over Xuan Ziwen's body.

Elsewhere.

Ju Zi stood beneath the corridor, watching the nearly crazed Xuan Ziwen at the workbench, a satisfied curve lifting her lips.

In her previous life.

The Milk Bottle had been a soul tool that would only be truly perfected and popularized much later.

But now.

Because she had made the suggestion, intercepted Huo Yuhao ahead of time, and spent heavily to keep Xuan Ziwen.

This soul tool had directly entered the world today.

Without her as a variable, Huo Yuhao might still have been starving in the Star Luo Empire, while Xuan Ziwen would still have been shut away in Mingde Hall, building things in isolation.

The feeling of personally speeding up the timeline and changing the course of history satisfied her greatly.

An intense sense of security and pride surged through Ju Zi's heart.

At the center of the courtyard.

Huo Yuhao sat in a chair, biting into a pastry, his expression utterly calm.

He did not understand what Xuan Ziwen was so excited about.

It was just a bottle for blue potions.

Back when he played games in his previous life, who would dare leave for a dungeon without several dozen blue potions in their backpack?

The only regrettable thing was.

For now, this thing still needed soul power manually injected into it beforehand to charge it. It could not absorb ambient energy by itself and automatically restore mana.

That counted as a minor flaw.

Just then.

Ye Guyi, who had just finished sword practice, came over.

She picked up an empty Milk Bottle that had just been assembled and turned it over repeatedly in her hand, weighing it.

"Can this iron can be used as a hidden weapon to throw at someone and kill them?"

Ye Guyi looked at Huo Yuhao seriously.

Huo Yuhao fell silent for a moment.

He sighed.

Clearly, for this pure, traditional assault-system soul master, there was simply no concept of high-endurance combat.

In her straightforward worldview, a lump of iron that could neither chop people nor deliver explosive damage was junk.

That way of thinking was probably beyond saving.

Suddenly.

Huo Yuhao's eyes lit up.

He stared at the row of identical metal containers on the table, and an exceptionally clear bolt of lightning flashed through his mind.

Their capacity was standardized.

Their materials were standardized.

Since second-grade Milk Bottles had precise, fixed calibrations,

Could they be used as units of measurement?

In the past, soul masters had always judged their own expenditure by feeling.

They had probably used about half.

There was only a little left.

Everything had to be prefaced with the word "probably."

But in the eyes of a modern test-taker, any energy that could not be quantified was complete nonsense.

At that thought.

Huo Yuhao's spirits rose, and he immediately grabbed several empty Milk Bottles.

"Sister Guyi, stop spacing out. Pour your soul power into them. Switch to the next one whenever one is full, until you've been completely drained."

Ye Guyi frowned deeply, her face full of confusion.

But seeing the feverish look in Huo Yuhao's eyes, she obediently pressed her hand against one.

Faint white light lit up one after another.

One.

Two.

Ten.

As time passed, the color drained from Ye Guyi's face at a visible rate. Eventually, she was completely exhausted and collapsed weakly into her chair.

"Exactly sixty-seven."

Holding a notebook, Huo Yuhao rapidly wrote down a string of numbers.

Then, following the same procedure, he turned his attention to Ju Zi and Xuan Ziwen beside him.

"Three and a half."

"I have three."

When it came to Xuan Ziwen, it took a full two hours before they finally emptied the entire reserves of this Soul Douluo.

"Three thousand one hundred and twenty-five."

Looking at the data listed in his notebook, Huo Yuhao's lips curled upward uncontrollably.

That was more like it.

If filling one second-grade Milk Bottle was defined as one unit of soul power.

Then the difference in strength between them instantly changed from vague levels into clearly defined numbers.

He himself was level fifteen, with three units.

Ju Zi was level seventeen but had cultivated slightly longer, with three and a half units.

Ye Guyi, who had just broken through level forty, had sixty-seven units.

And Xuan Ziwen, who was close to level eighty-one, had directly reached over three thousand.

Such a clearly quantified gap made the insurmountable chasm between low and high ranks visible at a glance.

With this absolute standard, the disparity became immediately apparent.

When testing new pills in the future, or deducing the circulation speed of the Heavenly Origin Art, they could directly obtain extremely precise parameter changes instead of blindly guessing.

Huo Yuhao slapped his thigh excitedly.

What high-endurance soul tool?

For someone whose bones were filled with the spirit of scientific research,

This measuring scale, capable of fully quantifying and datafying supernatural power, was the fucking epoch-making creation!
