Chapter 145 Using Scientific Logic
On Qingyao Mountain, a flying boat soared into the sky and flew directly towards Dongyan.

Geng Yunyi stood at the bow of the boat, his handsome face was covered with dark clouds.

The disciples who were ordered to go to Dongyan County just sent back the news that hundreds of tragic dead bodies were found outside the county town. Everything in the county town seemed to be normal, but in the clear sky and broad daylight, no one entered or left the city, which was obviously abnormal.

Along with Ren Suxin and Tong Qianling, they dispatched three Jindan real people at one go, which shows that Fu Dongzhi attaches great importance to mirages.

Ren Suxin also deliberately explained a few words to Bai Heji, but Tong Qianling remained silent from the beginning to the end, and there was always repulsion and dissatisfaction in his eyes.

Li Anxian kept muttering, he had talked to Anyutong a long time ago, this old woman hasn't given up yet?

The little clam girl stood quietly on the deck, folded her arms and said nothing.

Li Anxian came to her side and gently pulled her into his arms: "Don't think about it, it's none of your business. Since that mirage made a condition, he won't mess around."

"It's hard to say!" Geng Yunyi turned around, "Have you forgotten Chaosheng Island? He may not have come here for Miss Bai, but he may also be trying to divert his attention to delay time, search for souls and refine them to achieve magic skills."

The little clam girl flinched: "Our Mirage Clan's illusion is the strongest, but in other respects it's just mediocre. Illusion itself is powerless. If he has any ideas... it is indeed possible to take risks."

Geng Yunyi lowered his voice: "Nephew Li, since you can see through illusions, I will rely on you in a while!"

Li Anxian smiled wryly: "Uncle, I can only see through twenty or thirty feet at most, and I can't make it any further!"

"It's better than we can't see through anything!"

Li Anxian suddenly remembered the part about The Swordsman's Blind Fight: "Uncle, why don't we agree on a secret sign, such as a few consecutive movements, which can identify the identity in the illusion."

Geng Yunyi's eyes lit up: "Good idea, wait a minute, I'll discuss it with your Uncle Ren and Uncle Tong!"

After all, he turned and entered the cabin.

Li Anxian and Little Cengnu were the only ones left on the deck, they were close to each other, neither of them spoke.

After a while, the little clam girl asked softly: "Brother Li, can you give me a gun? Just one bullet will do."

Li Anxian's heart ached, he gritted his teeth and nodded: "Come with me!"

He dragged the little clam girl into the cabin, took out the refining array and some spiritual materials, and after a while, he made a small palm mine, and two magazines, one long and one short.

Taking out seven bullets and stuffing them into the short magazine, Li Anxian turned the muzzle of the gun upside down, and handed the palm thunder to the little clam girl: "The short one has only seven bullets, and the long one has twenty rounds."

He prepared several guns for himself, but in pursuit of firepower, all of them were space magazines, which couldn't fit into the storage bag, so he could only refine the regular version for her.

Bai Heji received it in her hand, and kept looking at it over and over again: "Thank you, Brother Li, I like it very much." After staying with Li Anxian for so long, I dare not say that I am familiar with all kinds of firearms, but I understand everything that I need to know, so I don't need to take it. I don't know how to use it yet.

Li Anxian pressed her hand: "I will not let you fall into the hands of the mirage, let alone let you have the opportunity to use this gun!"

As he spoke, he assembled another single, and handed over a rifle cartridge: "Here, I asked for this from Uncle Dongfang. The bullet is a mid-level high-grade flying sword. You can sacrifice it yourself. The critical moment Save your life!"

He only had three such bullets in total.

The little clam girl smiled sadly: "Brother Li, thank you."

"It's okay, it should be!" Li Anxian brushed the broken hair from the little clam girl's ears behind her ears, "The gun is a foreign object after all, I think it's best to find a way to break the illusion."

He has thought about this question all the way, but until now he has not figured out what the illusion is, and whether it has anything to do with electricity or magnetism.

The little clam girl couldn't answer, but Li Anxian had already taken out the iron rod and the wire, and wound an electromagnet: "Give me a screen, I can transform it into anything I want."

He is not good at spells, but he has rigorous scientific thinking—everything has a reason, as long as he masters the laws, he can find a way to break the illusion!
The little clam held a slender hand, and a blackboard full of pinyin letters appeared in the palm of her hand.

The electromagnet was energized and brought close to the blackboard, but there was no change in the image, not even a single wrinkle.

The magnetic field is useless, even if it is useful, he cannot create a strong enough magnetic field.

He moved his hand closer again, an electric spark flashed between his two fingers, and there was a snap.

Still no change.

Li Anxian couldn't take it anymore, he scratched his short hair fiercely, carefully recalled the remaining physics knowledge in his mind, and carefully considered what is an illusion.

From his personal experience, the illusion means that what the eyes see and what the ears hear are illusions, which is somewhat similar to the immersive VR before time travel.

Ok?
He suddenly grasped the important point. Since illusion is to deceive the eyes, it means that the essence of illusion is to change the visible light within a certain range by means of cultivating immortals!

Is non-visible light affected by illusion?
Li Anxian immediately asked: "He Ji, do you know what light is?"

The little clam girl was puzzled: "Light is light, what else can it be?"

Comrade Xiao Li glanced at the sky subconsciously: "Light is a kind of wave...electromagnetic wave...what the eyes can see is called visible light, and everything else is invisible light..."

Speaking of this, Tiandao still didn't respond, Li Anxian finally looked away with peace of mind: "Have you seen the rainbow?"

"I've seen it!"

"How many colors are there in the rainbow?"

The little clam girl counted on her fingers: "Red, orange, yellow, green, blue, blue, purple, seven kinds! Li Anxian, don't treat me like a child, okay?"

She couldn't understand why Big Brother Li would ask such a childish question, but Comrade Xiao Li breathed a sigh of relief quietly. Fortunately, mirages, like humans, can only see visible light. In other words, illusions can only see light. Manipulate visible light.

Li Anxian patiently explained: "A rainbow actually has more than seven colors. There is infrared light above red, and ultraviolet light below purple. The seven colors that can be seen by the eyes are called visible light, and those that cannot be seen are called invisible light."

The little clam girl immediately fainted: "Brother Li, why don't I understand what you are saying?"

Li Anxian was also scratching his head, explaining what is visible light and what is ultraviolet and infrared to a novice who doesn't understand anything, isn't this difficult for others?

He was stunned for a moment, thinking of Uncle Liu's full-band blocking interference, and a flash of inspiration flashed in his mind: Illusion changes visible light, and visible light is a type of electromagnetic wave. So, can electromagnetic interference be used to interfere with the illusion? Operation, thus destroying the illusion in one fell swoop?
The more he thought about it, the more he felt it made sense. Although he was not very knowledgeable in electromagnetism, he also knew that only electromagnetic waves of the same frequency could interfere with each other.

The problem is that although Li Anxian remembers the wavelength of visible light, he has never been exposed to the subject of electromagnetic interference, so he doesn't know where to start.

　The answer is really simple, I believe some book friends have already guessed it.

　　The fact that I can't get my head around it is actually when I was thinking about this chapter by myself, I got involved.
