305: Testing a new drug!

Returning to his room, Lin Yu paused for a moment as he passed the door next door.

No sound came from inside the room.

But with his current perception, he could clearly "see" the violent and chaotic energy fluctuations within the room.

There were intense crashing sounds, short energy explosions, and the girl's rapid, pained gasps.

Everything was perfectly sealed inside the room by top-tier soundproofing materials.

In Lin Yu's mind, his sister Lin Yao's stubborn little face appeared.

She was also fighting to become stronger in her own way.

Good.

This manic drive, this ruthlessness in squeezing herself to the limit, was eighty percent similar to his own.

The Lin Family's genes were indeed good.

He didn't disturb her.

Everyone has their own path to walk.

All he could do was clear all the obstacles on her path.

Lin Yu walked to his own door and pushed it open.

The room's furnishings were exactly as they were when he left: luxurious, yet empty.

Without a second glance, he walked straight to the center of the room and placed the silver briefcase on the floor.

The case opened.

Several prototype potions lay quietly in the velvet grooves.

[Eye of Analysis].

In Lin Yu's vision, a pale blue stream of data instantly covered the potions.

[Project: Instant Burst Potion (Prototype)]

[Effect: Takes effect within 0.3 seconds, providing the user with a fixed +100 point boost to all attributes, lasting for thirty seconds.]

[Note: Prototype potion, stability carries unknown risks.]

[Project: Life Serum (Purified and Improved Version)]

[Effect: Accelerates metabolism, quickly clears residual potion toxins and side effects from the body, and reduces the cooling time for continuous potion use by approximately 35%.]

[Project: Potion Rapid Absorption Catalyst]

[Effect: When mixed and injected with the target potion, it can shorten its activation time by approximately 50%.]

...The data was basically consistent with what Old Ghost had provided.

Lin Yu reached out and placed his hand over the [Instant Burst Potion].

[Card Transformation]!

A faint, imperceptible surge of Spiritual Power occurred.

The injection containing the pale gold liquid began to turn ethereal at a visible speed, decomposing into countless tiny points of light.

The light points converged, compressed, and reorganized in the air.

It took less than a second.

A card with a faint golden glow shimmering on its edges quietly took shape and fell into Lin Yu's hand.

On the front of the card was a cluster of burning golden flames.

He then proceeded to convert the [Life Serum] and [Catalyst] into cards one by one.

Only after finishing all this did he sit down cross-legged in the center of the room.

Handing over the subsequent research and development of these potions to Old Ghost would undoubtedly be the most efficient choice.

That old guy's talent in Pharmaceutics was terrifying.

But Lin Yu didn't do that.

Old Ghost's loyalty was built on interests and contracts.

That kind of contract wasn't a lifelong death pact like the one Zhao Tianyang had, where he offered up his soul.

It wasn't that Lin Yu didn't trust him, but rather that Lin Yu wasn't strong enough yet.

99% of his combat power was inflated power composed of Multiplication and duplication, which always made him feel uneasy.

That power was strong, but also hollow.

If someone with ulterior motives understood the logic of its operation, killing Lin Yu would be like child's play.

One must always be on guard against others.

Especially in this world where power is paramount.

Lin Yu spread his hand, and the three cards he had just made floated before him.

Immediately after, two more ancient-looking cards appeared in his other hand.

[Ghost Card] and [Multiplication].

He first pressed the [Ghost Card] onto the [Instant Burst Potion] card.

The two cards merged, a light flashed, and a brand-new [Instant Burst Potion] card that could be infinitely duplicated was born.

The experiment begins now.

With a thought, a duplicate [Life Serum] card appeared in his hand.

Without the slightest hesitation, he slapped the card onto his arm.

The card turned into a green warm current and instantly merged into his body.

This was the result of Lin Yu's optimization after understanding the logic of Card Transformation and card operation; it skipped the process of turning the card back into a potion and then injecting it, significantly increasing efficiency.

An even greater benefit was that his body wouldn't be covered in a bunch of mysterious needle marks.

A gentle yet powerful life force spread through his limbs and bones; every cell seemed to be activated, letting out joyful cries.

This was just to be safe.

Next, he duplicated an [Instant Burst Potion] card.

He took a deep breath.

He slapped this card onto his arm as well.

“Boom!”

An energy a hundred times more violent than before exploded within his body!

A pale golden torrent washed through every meridian and every corner of his body.

His muscles tightened instantly, and his bones let out groans of being overburdened.

An indescribable, terrifying sense of power, as if it were about to burst his body open, filled his every thought.

[All Attributes +100]!

Lin Yu immediately mobilized his Spiritual Power to inspect himself internally.

The upper limit of his Spiritual Power jumped steadily from five hundred points to six hundred points.

Strength, Constitution, Agility—every attribute received the same boost.

Strong!

Unprecedentedly strong!

He began to time it silently.

Ten seconds.

Twenty seconds.

Twenty-five seconds.

Twenty-seven seconds... twenty-eight seconds... the golden torrent within his body began to show signs of receding.

Twenty-eight point seven seconds.

The boost effect vanished completely.

A strong sense of weakness followed immediately.

All attributes instantly dropped to around 95% of their base values and were still slowly sliding down.

As expected, there were side effects.

Moreover, the duration had a slight discrepancy from the thirty seconds mentioned in the report.

Lin Yu did not panic.

He immediately used a [Life Serum] card.

The green warm current flowed in again, quickly neutralizing the sense of weakness, stabilizing his declining attributes, and starting a slow recovery.

Not a big problem.

Side effects could be offset with Life Serum, and the error in duration could be precisely calculated in battle as long as it was known in advance.

Next was the catalyst.

He duplicated another set of [Instant Burst Potion] and [Potion Rapid Absorption Catalyst] cards.

This time, he stacked the two cards together and slapped them onto his arm at the same time.

If the previous time was a torrent erupting.

This time, it was a volcanic eruption!

In almost zero point zero-something seconds after the cards touched his skin, that terrifying power completed its infusion.

There was no process, only the result.

All Attributes +100!

The activation speed was extremely fast!

This was the true "instant" burst!

Lin Yu began timing again.

However, after only thirteen seconds.

The boost effect began to recede rapidly.

Fourteen point two seconds.

The effect vanished completely.

The sense of weakness was even more violent than the last time.

Lin Yu immediately used another Life Serum card to stabilize his physical condition.

So that's how it is.

While the catalyst compressed the activation time to the limit, it also compressed the duration proportionally and intensified the side effects.

It was a trade-off.
