CHAPTER 753: DIRECT CURRENT DEFIBRILLATION? WHY IS IT SO DIFFICULT?

Garrett happily delegated the clinical trial tasks.

Having to stay up all night—no, having to dictate summaries while Tower Spirit MOSS wrote the experiment plans through the night was no problem;

Having to work hard on medical research to find a cure for a disease was no problem, that was his passion;

Raising bacteria, cultivating penicillin, making vaccines—this was also no problem, even though he was a clinical specialist and not in biology or pharmacology, he could still do it with gusto;

But having to travel all the way back to the Dwarf Kingdom, staying in that unhygienic cave, measuring heartbeats, listening to breaths, taking X-rays, injecting medicine dozens or even hundreds of times a day?

NEVER!

That’s what junior doctors do! And a whole team of them! These complicated and trivial tasks should be the responsibility of an attending physician leading a group of residents and interns!

Now, someone finally took over. Garrett hummed a tune as he started his daily routine:

Studying magic.

Ray Deflection, Dimension Door, Sanctuary, and especially the most important Arcane Eye, each had to be mastered. Of course, he also had to practice various defensive, escape, and attack spells as required by his teacher...

Garrett was very aware that the Lord of Thunder had tolerated him for a long time. Now that he was out of town, it was hard to check his assignments. If he still couldn’t master a few defensive spells by the time he returned, he might get whipped.

Currently, he had mastered Sanctuary, expanding the portable surgery room by twice its size;

He had learned Bio-Location and could now locate parasites, but locating bacteria still required further research;

Dimension Door was indeed difficult. Garrett had not delved much into spatial magic before, and he still had to learn from Precursor Teleport and Portal Analysis.

Hoping to master these spells to his teacher’s satisfaction before he returned was probably unrealistic.

"So Garrett, which one do you want to pick?"

Aurora asked, her head buried in the spell list without looking up. Having a high-level Tower Spirit was indeed good; MOSS could at least project the spell list collected by the Thunder Horn for them to choose from.

For some of the lower-level spells, they could directly retrieve spell models from the Thunder Tower via the Tower Spirit for learning...

"I think it’s better to learn attack spells." Garrett shrank his neck. His teacher’s task was to be proficient in at least one of each elemental attack spell: ice, fire, electricity, acid, force field, and sound wave.

As a magician, even in the medical field, attack spells could be unused but must not be absent. In case of bad luck, when a fool needed to be taught a lesson, he should have something to show.

"I think you can skip the fire element." Aurora bluntly quipped. Garrett nodded silently: with pure oxygen and explosives, he had already pushed the power of Fireball to above fourth level when he advanced to a fifth-level mage.

It was estimated that delaying the study of fire spells would not get him in trouble with his teacher. Otherwise, another "200-meter range, 300-meter blast area" might not be so lucky to have his teacher save him.

"I think there’s no need to rush with ice and acid elements either." Garrett shrugged: "It shouldn’t be difficult to push third-level spells to fourth-level power."

A sphere of cold could use liquid nitrogen as a casting material to increase power; a sphere of acid could use aqua regia and hydrofluoric acid to attempt upgrading.

Garrett estimated that an upgrade of one level from third to fourth should be achievable.

"So what are you going to choose?" Aurora turned her head, her eyes gleaming as she looked at him. The colorful light of the magical screen cast grids on his face, making him look eerily strange:

"Force field? Sound wave? I can give some advice on force fields, but not sound waves, I’m not familiar with them. Why not choose electricity? I’m most familiar with it! The Lord of Thunder will be happy if he sees you choose the Electric Sphere!"

Garrett also wanted to choose the electricity branch. No matter what, increasing output strength was essential. That "first direct current defibrillation, unknown how many joules for the electric claw," he never wanted to encounter again.

What if a patient had ventricular fibrillation?

External cardiac massage really wasn’t as effective as electrical defibrillation!

Garrett rubbed his hands together. With previous experience in deconstructing spell configurations, Aurora’s enthusiastic advice, and Archmage Carlisle available for consultation, he easily learned the fourth-level Electric Sphere.

But on the first day of practice, Aurora went crazy.

"Snap!"

"Failed."

"Snap!"

"Failed again."

"Snap!"

"Still failed..."

"What exactly is failing?!" Aurora paced around, her cheeks lit by the blue-white electric light, looking like a ghost, her glowing blue eyes flickering with white light:

"It’s clearly very successful! The attack power and range meet the requirements! Except that the release is too obvious, making it easy for the opponent to notice—but the Electric Sphere flies very fast, even if noticed, they can’t dodge!"

...I don’t really care if the release is too obvious since the chances of me personally going into battle are quite low. Garrett pointed to the measuring instruments Aurora had set up in the corner:

"The output strength is too high, and the duration is a bit too long..."

"Output strength..." Aurora choked on her words, covering her chest and coughing for a long time. Finally catching her breath, she lowered her voice and shouted at Garrett:

"Of course, the output strength has to be high! This is an attack spell! An attack spell! What’s the point of not increasing the output strength?!"

She suddenly fell silent, quickly looking around. Thankfully, they were in their own mage tower, with no one else around. Otherwise, if word got out that a follower spoke to their boss like this, the entire Thunder Horn would be ridiculed.

Aurora took a few quick breaths and continued berating:

"Any lightning mage dreams of being able to summon lightning at will, to summon lightning as powerful as the sky’s thunder. You lower the output strength and shorten the duration, what’s the point?"

"...The teacher wouldn’t agree with that." Garrett retorted with a stern face.

The Lord of Thunder had perfected lightning manipulation, and seeing the lightning behave obediently around him, one could imagine that control was the correct development direction for the lightning element.

Besides, Senior Sister Philby could already sense electron flows, and precise control of electrons seemed not far off. Aurora, are you sure you don’t want to head towards precision?

The mention of the Lord of Thunder made Aurora shrink back. Garrett briefly explained the development directions of several big figures, and she silently squatted in the corner, seemingly with a virtual sign above her head:

I want to be alone—

As for who ‘alone’ was, that was another topic, not very important.

Garrett continued to concentrate on practicing his electric spells. Direct current defibrillation involved converting 60Hz alternating current to high voltage direct current of 4~7kV, discharging to the heart within 2~4ms, with power reaching 360~400 joules.

He now needed to deconstruct the tasks and try each one. Lowering the power wasn’t difficult, using lower-level electric spells at most, but shortening the duration...

"2 to 4 milliseconds... 2 to 4 milliseconds..." Garrett mumbled as he continued practicing. Switching from the fourth-level Electric Sphere to the first-level Electric Claw, he kept practicing control:

Release!

End!

Duration, 0.5 seconds, or 500 milliseconds.

Release!

End!

Duration, 0.3 seconds.

Release!

End!

Duration, 0.22 seconds.

Garrett thought for a moment and realized he couldn’t just practice mindlessly. He looked down and deconstructed the spell model, using the Rune Encyclopedia given by his teacher and the structures he had previously deconstructed in his research, pulling out a module related to duration:

Increase—

Decrease—

Increase—

Decrease—

After tweaking back and forth, drawing seven or eight spell configurations, he tested again. This time, the duration impressively reduced to 0.01 seconds, or 10 milliseconds.

Effective!

Adding a duration control structure to automatically control the spell duration was effective! Next, he needed to minimize the spell’s duration—

Garrett rolled up his sleeves and continued working. After three consecutive days of testing and modifications, he finally managed to control the casting time of the lightning spell within 2 milliseconds. Now, he needed to master the casting timing.

Garrett went to the top floor of the mage tower, setting up a receiver beside MOSS and connecting it to the core of the tower. Taking a deep breath, he instructed the Tower Spirit:

"MOSS, display the stored ECG. I will release Electric Claw according to the rhythm, and you help record the time point of each Electric Claw passing through, marking it on the ECG."

"Yes, boss." MOSS responded methodically. The light screen lit up, the R wave, P wave, Q wave, and S wave of the ECG advancing rhythmically.

Garrett stared at the ECG on the light screen, his mental power triggering the spell structure of Electric Claw, gently releasing it—the magic flew out—

"Snap," the blue-white electric light lightly struck the receiver, silently absorbed by the tower core.

A prominent red dot appeared instantly on the light screen.

Garrett eagerly looked at it. Great, not completely accurate, but not far off. If current passed through the heart at this time point, defibrillation was impossible, but causing further arrhythmia was highly likely...

"Again!" That was just a

slow reaction! Concentrate, calculate the lead time, maybe it can succeed!

"Snap."

"Snap."

"Snap."

"Snap—"

Great, the red dots on the ECG waveform were scattered randomly. Two even landed in the vulnerable period of the ventricle, causing arrhythmia even without ventricular fibrillation!

"Ah—why is direct current defibrillation so difficult..."
