Chapter 423 From Prophecy Magic to Electrocardiogram!

Gretel's knowledge of electrocardiograms in her previous life... well, it can't be said that she didn't understand them. At least, as a deputy director of the emergency department, he can use an electrocardiograph and identify some of the more dangerous patterns. If he cannot distinguish them, he will know to call the cardiology department for consultation. Then, he also explained the principles of cardiac myoelectricity very clearly.

But, you let him rub his hands on the electrocardiograph...

Just kill him.

This really can't be done.

Electrode tubes, amplifiers, filters. By the way, we still need to write programs. Gretel touched the melon seeds on his head. Although his hair was still thick after time travel, it was not so bad!

So what to do? The display problem has been solved, how to solve the export problem? The temperature required for electrode sheets...coupling agent...seems to be close to absolute zero. I don't know if Yinlong can rub it by hand...

"Gretel, what are you thinking about?" Cerela suddenly jumped over and poked him: "I turned on [Detect Thoughts] and I can't read it... What is an electric pole? What is a superconductor?"

"What did you say?!" Grete turned his head suddenly. His eyes were shining brightly as he stared at Cerela. The silver dragon girl subconsciously took a step back:

"Electricity... electrodes! And superconductivity... what is that? Why do you want us to do it?"

"Not that sentence! The previous sentence!" Gretel waved his hand eagerly. The silver dragon girl took another step back, murmuring guiltily:

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

"Detecting thoughts! By the way, detecting thoughts!" Grete 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 as he walked:

"Detect thoughts...collect information...interpret...what is the information collected? Waves? Brain waves? Could it be brain waves? - Bernard! Bernard!"

Barbarian followers scurried out. Gretel gasped for breath and grabbed him:

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

Bernard didn't know why, but he still ran back with a clanking sound, and then rushed back with his helmet in his arms like a whirlwind. This helmet was made for Bernard by a dwarf master craftsman. It was made of solid materials and had an extra pair of metal horns on both sides. As soon as Gretel grabbed it, his arms immediately sank down.

"Good weight……"

Grete muttered and raised the horned helmet, holding the horns on both sides with both hands, and slapped it on his forehead. The helmet is big, the head is small, and the vision suddenly becomes dark. He had no time to adjust and gropingly turned to Cerela:

"Put another detect thought! Quick! - can you read it?"

"It's not bad, it's such a big hole!"

"What about this?" Grete pulled up his visor. After a moment of silence, the silver dragon girl's voice came out with a slight hum and distortion:

"Not very good...but metal can block spells! What does this mean?"

It's really not convincing enough. Grete's mind sank into the space bag, and he rummaged through it, but couldn't find what he wanted. After thinking for a moment, he raised his horned helmet and revealed half of his face from underneath:

"Cerilla! Can you shape the metal - pull the silver ingots into thin silver threads and weave them into a uniform net to cover me inside?"

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

The silver dragon girl's magic shaping ability is still a little bit behind. Although Gretel is quite skeptical, she is actually impatient. Finally, after Gray promised to show her a device that could block electric current, Cerela ran decisively and dragged her aunt over.

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

Grete squatted in personally. As soon as the cage was closed, Cerela couldn't wait and shot a small bolt of lightning out. The electric sparks flashed on the wire and suddenly went out, but Grete stood firmly inside, looking at her with a smile, unscathed.

"Huh? Why is this?"

The eyes of the two silver dragons lit up. Gretel urged:

"I'll tell you later! - Hurry up, let's detect thoughts again!"

"I know! - think of whatever you want!"

The two silver dragons threw [Detect Thoughts] together. Soon, they looked at each other in surprise:

"It's indeed harder than before!"

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

"There are a lot of holes in it!"

"How about weaving the wire mesh a little thinner?"

Ophelia simply appears in dragon form. She lay down in the middle of the hall of the medical area, closed her eyes, and her whole body shone with silver light. Activating his mental power, the steel wire mesh around Gretel collapsed on its own and flew into the air. The steel wire was pulled by invisible hands. One meter became two meters, two meters became four meters, and then, it was connected into a denser grid...

Grete squatted into the cage automatically and consciously. The second round of [Detection of Thoughts] was thrown, and sure enough, the protective effect was improved again.

"why is that?"

Two eyes the size of silver plates stared at Grete, and he exhaled from his nostrils, and puffs of white mist sprayed directly onto Grete. Except for Bernard, the other barbarians had already fled back to their rooms. Only Gretel tried his best to explain to the silver dragons across the cage:

"Actually, the brain, like the heart, also produces electric currents and brain waves that can be observed... I personally suspect that the magic of [detecting thoughts] is the reception and interpretation of brain waves... And the method, ah no, The steel mesh can shield the current, so it will affect the reading of brain waves by [Detection of Thoughts]..."

[Detect Thoughts] is a second-level 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 creatures (possessing intelligence and consciousness);

In the second stage, scan the number of thinkers and their intelligence value (Greit strongly suspects that it is the intensity of brain wave activity);

The third round is to detect all surface thoughts in the area. 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 Gretel's ability to decide which piece is responsible for which...

He turned his expectant eyes to Ms. Silver Dragon. Please help! Please disassemble it! Please dismantle the spell structure one by one to see which part is responsible for scanning the surroundings, which one is receiving, and which one is reading!

Without saying a word, Ophelia began to dismantle it. In the air, phantoms danced and flickered, and fine fluctuations of mana kept appearing and disappearing. For an adult silver dragon, manipulating a few low-level magics is almost like eating and drinking, and there is almost no feeling of mana consumption.

Soon, Ms. Silver Dragon’s fingertips sparkled with lightning:

"You can indeed receive electricity! - Gretel, come out and let's try again!"

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

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