Chapter 261

Known: [See through Invisibility] can see the spiritual light of living beings.

Question: What is the spiritual light of life?

As he approached the answer, Garrett became calmer instead. The next verification work required sufficiently refined prerequisites — even with complete prerequisites, many newly-minted students experienced experiment failures, experiment failures, experiment failures...

Garrett calmed down and began manipulating scales, pipettes, beakers, and flasks. Preparing Renshi’s solution, he welded zinc and copper plates together to make a zinc-copper bow. Hmm, magic made things much easier; he heated them until they softened, directly joined them together, and then cooled them down... Done!

Perfect!

Then, Garrett began preparing frogs, nailing them to wooden boards, destroying their brains and spinal cords, and cutting off the upper half of their bodies... Completing the sciatic nerve-gastrocnemius muscle specimen. The laboratory was bloody, barbaric enough to make barbarians grimace, but Garrett remained impassive throughout, even showing some excitement.

Just kidding, even though medical students weren’t as accustomed to dissections as their biology colleagues, they had dissected dozens of frogs, mice, cats, and dogs, so who would fear such scenes!

And throughout, Garrett even maintained his meditation, not being swayed by emotional fluctuations. Under the [See through Invisibility], the spiritual light of life silently flickered and quietly fell into the meditative field of view.

What excited Garrett was that even with only a piece of spine and frog legs remaining, a faint spiritual light could still be seen in his meditative vision.

So...

Zinc-copper bow, dipped in Renshi’s solution, stimulating the sciatic nerve!

The moment the metal pieces touched each end, the frog’s gastrocnemius muscle contracted violently. At the same time, the spiritual light in Garrett’s meditative vision visibly jumped up!

Correct!

The magic [See through Invisibility], seeing the spiritual light, was most likely the bioelectricity of organisms!

Then...

What is the mechanism of action of [Alleviate Pain]?

Garrett recalled the content from the "Physiology" textbook. The principle of human feeling pain is divided into three steps:

When the body is damaged or inflamed, damaged cells release pain-inducing substances, such as inorganic salts like potassium, hydrogen, calcium ions, amines like serotonin, histamine, prostaglandins, and so on. For example, a large proportion of dysmenorrhea is caused by prostaglandins. Taking ibuprofen in advance can inhibit the production of prostaglandins, achieving analgesic effects;

When nerve endings are stimulated by exogenous pain-inducing substances or activated by endogenous pain-inducing substances, receptor potentials are generated, which then trigger conductive action potentials to transmit the damage information along the nerves to the brain. As can be seen, this process involves bioelectricity;

The cerebral cortex integrates the pain information, and finally, the body feels the signal of "pain" —

So, at which step does [Alleviate Pain] work?

Garrett decided to do another experiment. This time, following Madame Syatt’s guidance, he narrowed down the range of action of [Alleviate Pain], narrowing it down, and narrowing it down again.

In the spell model of [Alleviate Pain], the structure determining the casting coverage is a structure somewhat like an hourglass. Neither end is a standard cone, but slightly twisted and coiled, with undulating patterns, somewhat like ice cream on top of a cone.

For Garrett, who had experience in constructing meditative shells, this kind of spell model was not too difficult. Isn’t it just twisting and turning, patterns? Everything, everything, is a mathematical problem!

After calculations, building function models, adjusting parameters, a series of steps, he had already narrowed down the range of magic’s effect from covering the entire body to the size of a bowl.

To narrow it down further, it wasn’t that the parameters couldn’t be adjusted, but that Garrett’s mental power and spell control couldn’t support it...

Garrett took another frog, nailed it to a board, and cut the skin on its leg with a knife. [See through Invisibility]! [Alleviate Pain], target, frog’s head!

In his meditative vision, the spiritual light fluctuations in the frog’s head decreased and softened, while the fluctuations in its legs remained strong. Was it that it couldn’t feel pain anymore, but the limbs were still twitching involuntarily? It’s a pity that he never learned the part of soothing animals in natural god’s teachings; he couldn’t connect with the animal’s perception. If it were Reverend Matthew here, it would be better...

Garrett thought for a moment, canceled the spell, and threw the second [Alleviate Pain] to the frog’s legs. This time, in his meditative vision, the spiritual light in the frog’s legs calmed down, while the light in its head remained calm. There was no choice; Garrett used the traditional fixed method, nailing the frog’s four feet with nails, and it hurt.

Hmm, so it means that the [Alleviate Pain] spell can at least suppress some of the sensory nerve’s bioelectric conduction within the range of the spell’s coverage...

Then, if the nerves are suppressed, is it possible that after cutting off the nerve response, the sensation of pain in the terminal limbs will no longer be transmitted to the brain?

Garrett impulsively threw a spell onto his thigh. Then, he bent down and pinched his calf hard.

It really didn’t hurt!

Garrett continued to split the spell model. In this spell, the part that determines the nature of the spell resembles a flower, and underneath the flower are numerous coiled roots. Garrett tried omitting the part of the roots, casting the spell again...

The frog struggled violently. However, when the spell was thrown to the frog’s head, the frog immediately calmed down, and the spiritual light in its head also became gentle, with no more violent fluctuations. And by omitting the flower part and directly outlining the roots, casting again—

Effective on the limbs, ineffective on the head!

Interesting. Garrett’s eyes gleamed, recording quickly. So the "flower" part controlled the central nervous system, making the brain unable to recognize pain, while the "roots" part suppressed sensory nerves, inhibiting bioelectric conduction?

This mechanism is very interesting!

Moreover, after splitting and narrowing the range of the spell’s coverage, the magical power consumed by this magic directly reduced from second-order magic to first-order magic. Such changes were certainly not very useful in combat. The smaller the coverage area, the lower the likelihood of hitting the target. If there were multiple wounds on the body, it would be even more impractical — it blocks here but not there...

But in medical treatment, it would be very useful!

Local anesthesia!

If local anesthesia is possible, why use general anesthesia!

If spinal anesthesia is possible, there’s no need for general anesthesia!

Wasting anesthetic, no, wasting magical power, and also affecting the patient’s recovery!

Tomorrow, yes, tomorrow, go to the clinic and give it a try! If there are no suitable patients in the clinic, he can go to the dock, to the fleet. There, the porters and soldiers are often involved in bumps and scrapes, so he should find an opportunity!
