The work that followed was like breaking bamboo – swift and effective. Ophelia’s claws moved quickly, weaving magical power, and soon, she had connected the part of the "Thought Detection" spell that receives body surface electrical currents to the cloud screen.


    Fortunately, the dismantled structure was only a small part of the "Thought Detection" spell. Even with the addition of the cloud screen, the overall casting strength was merely at the level of a first-order spell. The two spell configurations were connected, followed by receiving, amplifying, and conducting the signals—all in one go.


    "Garrett! Come! Let me measure you now!"


    The Silver Dragon Lady commanded. Seraina, beside her, was glowing with excitement and seemed ready to jump in. Her palm raised, fingertips sparkling, as if the dragon claws were about to spring out...


    Garrett shivered involuntarily. When he measured the myocardial electrical currents of rabbits and dogs, he had to shave the fur off their chests and insert silver needles. Now, it was his turn. Although there was no fur to shave on his chest and no need for silver needles thanks to the "Thought Detection" spell, he still...


    "Don’t strip my clothes off!" Garrett, as if surrendering, raised his hands and stepped back:


    "Just measure both wrists! That should be enough!"


    "Hmm?"


    "Hmm..." He automatically bent down, pulled up his pant leg, and dragged his left sock down to below his ankle:


    "And the left ankle as well..."


    Just testing the limbs would suffice! As for the chest leads, considerations such as specific positioning and how to operate 12 leads simultaneously to display 6 electrocardiograms could wait until he mastered this spell!


    Soon, long and short lines appeared on the cloud screen. Garrett pointed out to the Silver Dragon Lady, constantly changing the display details to make the electrocardiogram look familiar:


    "Divide the screen with vertical and horizontal lines into uniform squares,... each pair of vertical lines represents 0.04 seconds, each pair of horizontal lines..." Oh no, how to create the voltage scale?


    How to determine the voltage that corresponds to 0.1mV in height?


    Never mind, just adjust it roughly to the height I’m familiar with!


    Garrett made up his mind and, with a show of confidence, directed the Silver Dragon Lady to adjust the magical details:


    "Each pair of horizontal lines represents one unit of electrocardiographic strength. Lower the peaks a bit... lower... then raise a bit, and lower again, just like that! Don’t display the electrocardiographic strength with vertical bars; connect the dots at the tips of the bars to draw a line!"


    It must be acknowledged that Ophelia’s magical control was strong enough and her temperament patient and meticulous. Garrett had one request after another, one idea after another, and she actually adjusted them over and over again without complaint. Seraina, walking back and forth, found herself unable to keep up with her aunt’s pace due to her insufficient magical strength and control.


    I can’t..."


    Garrett gave a wry smile. In clinical practice, each of the 12 leads is meaningful, each line, each wave change represents a possibility. If mental strength can’t hold up, of course, one could first look at six leads, then the other six, or even just one at a time, but...


    Heart disease strikes swiftly. From vigorous exercise to collapsing, it often happens in an instant. The window for resuscitation is usually only a few minutes. At that time, the faster one can read an electrocardiogram, the better...


    To simultaneously place nine electrodes and display twelve leads, this task might be optional, but there must be some capacity left in this spell configuration!


    "You..."


    Ophelia bowed her head, staring at him steadily. In her pair of dish-sized blue eyes, the reflection of the little mage looking up boldly, firm and unyielding, was visible.


    "Stubborn little guy." The Silver Dragon Lady chuckled lightly. She suddenly cast a transformation spell, becoming a Silver Dragon again. Her fingertip hooked, and the "Endless Ink Pen" broke free from the roots, flying directly and leaving a trail of shadows on the paper:


    "If you want to display twelve leads, here needs to be changed like this... here too... here... here... here..."


    Swoosh, swoosh, swoosh, swoosh. Garrett quickly slapped his spatial bag, spilling out a thick stack of white paper. The movements of the Silver Dragon Lady were so fast that the writing papers flew up one by one, landing under the pen:


    Straight lines, curves, dots... circles, ellipses, triangles, squares, diamonds... numbers, symbols, formulas...


    The speed was dazzling. Sheets of paper filled with writings and drawings flew up, quickly covering a wall. Yet, the Silver Dragon Lady was still not satisfied, occasionally glancing at the wall, directing the feather pen to write a few lines, then looking again and adjusting the spell configurations...


    Watching the "Endless Ink Pen" moving swiftly on the paper, Garrett had only one thought:


    "You’ve become a mature feather pen now, you need to learn to deduce magical formulas by yourself..."


    And, thankfully, when the Newcomer Magician Award was given, the prize was a pen with endless ink. If it were an ordinary pencil, fountain pen, or even a ballpoint pen, it really wouldn’t have withstood the Silver Dragon Lady’s writing!
