It's not that hard to open a hospital in another world, right?

Chapter 423 From Prophecy Magic to Electrocardiogram!
Gretel's understanding of electrocardiograms in his previous life... Well, it can't be said that he didn't understand it.At least, as a deputy director of the emergency department, he can use an electrocardiograph and recognize some dangerous patterns, and if he can't distinguish them, he will call the cardiology department for consultation.Then, he also spoke clearly about the principle of cardiac myoelectricity.

But, you let him rub the electrocardiograph...

kill him.

This really can't be done.

Electrode tube, amplifier, filter.By the way, but also to write programs.Gretel touched the seeds of his head, although his hair is still thick after time travel, it is not such a waste!
So what to do?The displayed problem is solved, how to solve the exported problem?Electrodes...coupling agent...the temperature required for superconductivity seems to be close to absolute zero, and I don't know if Yinlong can rub it by hand...

"Gretel, what are you thinking?" Cerilla suddenly jumped over to poke him: "I can't read it even after playing [Detect Thoughts]... What is an electric... pole? What is superconductivity?"

"What did you say?!" Gretel suddenly turned his head.His eyes were shining brightly, staring at Cerilla, the silver dragon girl took a step back subconsciously:
"Electricity... electrodes! And superconductivity... what is that? Why do we have to make it?"

"Not that sentence! The previous sentence!" Gretel waved eagerly.The silver dragon girl took another step back and murmured guiltily:

"Detecting thoughts... I just want to see what problems you encounter... Well, if you don't like it, I won't let it go..."

"Detect thoughts! By the way, it is to detect thoughts!" Gretel jumped up, trembling with excitement.He walked from the desk to the left wall, then from the left wall to the right wall, muttering to himself while walking:
"Detecting thoughts... collecting information... interpreting... what is the information collected? Waves? Brainwaves? Could it be brainwaves? - Bernard! Bernard!"

The savage followers came hurrying out.Gretel gasped for breath and grabbed him:

"Your helmet! Lend me your helmet! Quick!"

Bernard didn't know why, so he ran back ding ding dong dong, and rushed back with his helmet in his arms like a whirlwind.This helmet was made by a dwarf craftsman for Bernard. It is made of solid materials and has an additional pair of metal horns on both sides. As soon as Gretel snatched it, his arms sank immediately.

"Good weight……"

Gretel muttered and raised the horned helmet, holding the horns on both sides with both hands, and slammed it on his forehead.The helmet is big, the head is small, and the eyes are suddenly dark.He didn't have time to adjust, and turned to Serila fumblingly:
"Put another Detect Thought! Quick! — can you read it?"

"It's okay, such a big hole!"

"Then what about this?" Gretel put on his visor with a bang.After a moment of silence, the voice of the silver dragon girl came with a bit of humming and distorted:

"It's not very good...but metal can block spells! What does this mean?"

Not convincing enough.Gretel sank into the interspatial bag and rummaged around, but couldn't find what he wanted.After thinking for a moment, he raised his horned helmet, revealing half of his face from underneath:

"Cerilla! Can you shape metal—that is, draw silver ingots into thin silver threads, and weave them into an even net to enclose me?"

"...You take off that cover before you speak!!!"

The silver dragon girl's spell shaping ability is still a bit weak. Although Gretel is quite skeptical, she is actually impatient.In the end, after Gret promised to show her a device that could block the electric current, Cerilla ran decisively and dragged her aunt here.

Then, according to Gretel's request, Ophelia personally took the action and molded a large steel ingot provided by Gretel into a Faraday cage with a mesh of only 1 square centimeter and interlocking with each other.

Gretel squatted in himself.As soon as the cage was closed, Cerilla couldn't wait, and shot out a small bolt of lightning.The spark flickered on the wire and then went out, and Gretel stood still inside, smiling at her, unharmed.

"Huh? Why is that?"

The eyes of the two silver dragons lit up.Gretel hurriedly urged:
"I'll tell you later!—Come on, let's try to detect thoughts again!"

"Got it!—you can think of anything you want!"

The two silver dragons threw [Detect Thoughts] together.Soon, they looked at each other in surprise:
"It is indeed more difficult than before!"

"It shouldn't be, the steel wire is so thin, much thinner than the thickness of the helmet!"

"There are many holes in it!"

"How about weaving the wire mesh thinner?"

Ophelia simply took the form of a dragon.She lay on her stomach in the middle of the hall of the medical area, closed her eyes, and her whole body was shining with silver light.The mental power was activated, and the wire mesh around Gretel disintegrated by itself, flying in the air.The steel wire was pulled by invisible hands, one meter became two meters, two meters became four meters, and then connected into a denser grid...

Gretel crouched automatically and consciously into the cage.The second round of [Detecting Thoughts] was thrown out, and sure enough, the protective effect was improved again.

"why is that?"

Two eyes the size of silver plates stared at Gretel, exhaled from his nostrils, and clouds of white mist sprayed directly on Gretel.Except for Bernard, the other barbarians had already fled back to their room. Only Gretel tried to explain to the silver dragons through the cage:
"Actually, the brain, like the heart, also generates electric currents and produces observable brain waves... I personally suspect that the magic of [Detecting Thoughts] is the reception and interpretation of brain waves... and Fa, ah no, The wire mesh can shield the electric current, so it will affect [Detect Thought]'s reading of brain waves..."

[Detect Thoughts] is a second-order magic.The scope of the spell is a cone-shaped area, and the casting process is divided into three stages:

In the first stage, scan the casting range to see if there are any thinking (intelligent, lucid) creatures;
In the second stage, scan the number of thinkers and intelligence values ​​(Grete strongly suspects that it is the intensity of brain wave activity);

In the third round, perceive all surface thoughts in the area.From this it can be seen that this magic is composed of at least three different configurations, and there may be some structures that relate them to each other.However, it is beyond the scope of Gretel's ability to control which part...

He cast his expectant eyes on Ms. Yinlong.Please help!Please disassemble!Please disassemble the spell structure one by one to see which one is the tube to scan the surrounding area, which tube to receive, and which tube to read!
Ofelia started to disassemble without saying a word.In the air, phantoms danced and flickered, and subtle fluctuations of mana kept appearing and disappearing.For an adult silver dragon, manipulating a few low-level spells is almost like eating and drinking, and the consumption of mana is almost unfeeling.

Soon, a flash of lightning flashed from Ms. Yinlong's fingertips:
"I can indeed receive electricity! - Gretel, come out, let's try again!"

After struggling for a long time, I finally decided to use magic to detour...

Electrodes, wires, resistors, amplification, filtering, programming, it's really too difficult...

Ask for subscription, ask for monthly pass, ask for recommendation ticket, ask for book review, ask for various...
