Thinking of this old rival, Fen hated it so much. Although he has never won this position, and even almost died under his hands several times, he has made great efforts to the fall of the sun god.

It's just that the man in front of him, how can he attract the old god so easily. Is it because his abilities and methods are too direct to the origin of things, which is equivalent to stealing the power of the old gods, and this behavior has become the key to the revival of the old gods?

It seems necessary to make it clear. Completely ignoring the poor insects beside her who had turned into ashes, and didn't care about the dark corners of the first floor of the inn, where the same poor insects had turned into ashes, she turned a face and said, "Can you stop using such magic?" ”

The sudden question also felt inexplicable to the person being asked. Lin cautiously looked at the lich in front of him, looked up and down, and asked suspiciously, "The sun doesn't seem to have left any harm on you, what's wrong?" ”

"Remember what happened when you first found Earth? While connecting with another world, it also attracts the old gods to absorb the power of the new world and resurrect it. ”

Someone's reaction to danger should not be said to be unpleasant. Just hearing Fen raise his head, he asked nervously, "What's the matter, which old god is involved this time?" ”

Although it is rare to ask about the Lich about the past. But these days of getting along, Lin also knows the reason why Fen swept the whole world in the past, and that is the hatred of the old gods. Knowing that the other party has a grudge against those gods, if he wants to provoke those long-dead bosses, this is too hard and too long, do you want to try the color of the former demon king?

If you know the taboos of others, you should know how to avoid them. On the one hand, this does not offend people, and on the other hand, it also protects oneself. Lin Ke had no doubt at all that if one day he was really corrupted by the old gods, Fen might not be thinking about how to save himself, but how to dismantle himself would be more relieved.

As for someone's anxious appearance, Fen also calmed down a little, and while organizing his words, he also thought about the cause and effect. What is it that triggers the power of the Old Gods? "When you were just casting the Light Spell, I smelled the Sun God. What just happened, why do vampires get burned to ashes as if they were being hit by the sun. It was just normal magic, and I didn't feel any power at all. ”

"Yes, the Light Technique is the basic magic of the apprentice level, and it is not offensive under normal circumstances except for lighting. However, the light technique I use is still slightly different from normal magic, and the difference is in the wavelength of light. ”

"The wavelength of light? Do you mean the electromagnetic spectrum? You researched some time ago, but there is no one below. ”

"Yes." Originally, the research was carried out to improve the accuracy of celestial observation. But because I found the earth and confirmed it, I put it on hold. "The electromagnetic spectrum that was studied at the beginning was actually an advanced research project that included the wavelength of visible light. Visible light, on the other hand, is the form of various colors, rays, and energy that we see now, and it is usually composed of a continuous set of spectrum of light spectrum. To put it in a more vernacular way, light rays that are common in nature are actually formed by the mixing of multiple groups of electromagnetic waves of different frequencies. This can be clearly observed from the prism scattering experiment that I showed you before. ”

At the beginning, in order to allow Fen to assist in the programming of observation and calculation, there was a more in-depth analysis and discussion of this knowledge. So as soon as she mentioned it, she remembered the relevant knowledge and content.

"It's just what I told you at the time, and it doesn't contain a question. That's everything we can see with our naked eyes, what kind of spectrum it is, and what kind of impact it will have. ”

"Ahh Fen looked at the ashes that were beginning to dwindle at her feet. Because it was summer, not only were the doors and windows not closed, but the walls of the inn were also leaking a little because of the dilapidation, which brought a slight breeze and gradually carried away the ashes that were once vampires.

Noticing Fen's gaze, Lin pointed to these poor insects that had been burned to ashes and said, "It was just an accident. At first, I just wanted to do a good job of lighting the inside of the Great Sage's Tower. ”

"Lighting?" Tilting her head, Fen thought back to the magic tower where she had lived.

Lin went on to explain, "When I settled in the Tower of the Great Sage, the original lighting equipment was arguably non-existent. At night, if you want to move around the tower, you can only hold a candlestick or perform your own light magic. There is only the core room, and there are still a few night pearls that can barely be used for lighting. Until what you see, it has been transformed several times. ”

"Until it becomes a weapon?" Fen said suspiciously.

"yes, into a weapon." Lin remembered the ubiquitous beam trap placed in the magic tower. But now that it's someone else's, it's useless to think about it. He continued: "Back to lighting. Since it's a light created by magic, it's controllable. So how bright it should be is the most suitable. Artificial light can easily cause adverse effects on the human eye due to the negligence of the original design. On Earth, there is a lot of research on blue light that hurts the eyes. So I intuitively imitated the daylight like the sunlight and the nightlight like the moonlight, because this is the light that the human eye is most accustomed to. ”

"The sun." Fen groaned, thoughts spinning in her head.

"The first accident happened when a group of vampires broke into the tower one night and took two little girls hostage. ——”

Halumi pointed to his companion dissatisfied, and said, "Kaya was bitten, but I didn't. ”

The black-haired, brown-skinned girl who was accused was poking her cheeks in dissatisfaction.

"—I wanted to have a good conversation with the incoming enemies, so I switched from nightlight mode to daylight mode, and they all died. The death is just like what you saw today. ”

As he spoke, Lin passed on the combined wavelength data of the two rays he had detected to Fin. And said: "At that time, I was also surprised to find that the light technique had such an effect. I thought vampires would be afraid of sunlight because of the mysterious power it contains. But after that happened, I wondered if it was a specific combination of wavelengths, or a specific wavelength band, that was the cause of their death, but I couldn't be sure. Although there were several waves of vampire attacks after that, they were basically burned out with a single lamp, so it was too late to determine this. After a few waves of death, there were no more vampires attacking the Great Sage's Tower. And then you were resurrected. ”

"In other words, during the time I stayed in the Great Sage's Tower, the light in the tower during the day was what you call the wavelength of sunlight." Fen confirmed.

"Yes, it was already then."

"But at that time I didn't feel the revival of the sun god. In other words, the key is not what kind of light, but who uses what light, or who uses light to do things. ”

Regarding Fen's speculation, Lin shouted in shock: "Is this okay? ”

"What's not to do. At that level of life, the expression of power is not justified at all, and some are just concepts. And the bizarre choices made by more people in order to get out of a road that no one has traveled are really speechless. ”

"Then doesn't that mean I can't use this method against vampires anymore?" At the end of the day, it's all that someone is worried about. After all, the enmity with this group is not small, especially today, there are a few new ones. If you abolish your martial arts, you won't be hunted down to the ends of the earth until you die.

"Not really. I think if you use it in a different way, you should be able to circumvent it. However, the actual situation has to be tested to be determined. ”

"It's that simple. To simulate the wavelength of sunlight, you must first have a carrier that can be simulated. This carrier must be in the form of energy, it must be controllable, and most importantly, it must have the physical properties of a 'wave'. ”

Without further ado, Fen slapped Parsley, one of the four magic spears he had brought with him, on the table. The eldest sister of the club, who slaps a gun on the table to give people a warning, and has the momentum of spraying if she doesn't agree.

Perhaps the design of the magic gun is not based on the idea of a pure energy weapon, but it is not impossible to change the way it attacks. In particular, the four guns that Fen used were powered by power. Unlike the one used by Lin and the two apprentices, it had to be paired with live ammunition to increase the number of shots.

Since it can be changed, then there is nothing to say, just do it. Lin took off the middle finger ring in his left hand and opened the safety lock of the parsley. Encryption and security were never considered in the previous design programs, and the main reason was that they didn't know where to start, except that they planned to fish in troubled waters.

As a weapon, the magic gun must of course put more effort into reliability. Otherwise, in the course of the battle, he was remotely invaded and changed to a dumb gun, which is not enough to kill himself. After researching with Finn, the security measures decided on were the physical locks that were now opened. And the ring that unlocked, in addition to Lin You's one, Fen also had the same ring.

As soon as the safety lock of the magic gun was opened, the two of them were connected to the bottom of the gun's program. The two of them, who had long been familiar with each other, quickly found the program code to modify the form of the energy bomb, and made various possibilities into different selection modes in one go.

It's just that...... The result? I don't know.

"How do you verify that?" Having completed the magic gun again, Lin asked himself the first question.

The same problem plagued a certain lich. If you can't give the finished work a try, it's a lie to say that Fen doesn't have an itch. So how do you experiment? Suddenly, a thought crossed her mind, and Fen went to the bar and pulled out the shopkeeper who was hiding behind.

"Don't kill me, don't kill me." The frightened shopkeeper held his hand in front of him and pleaded in panic.

Directly slapped twice, Fen asked the silent shopkeeper. "You should know where these vampires came from."

"You...... What do you want to do? "yes, what do you want to do?"

The first sentence was asked by the shopkeeper who was beaten, but the latter sentence was asked by Lin, who also wanted to know the answer.

But seeing the amorous Fen, he smiled back, and said in a sweet voice that he had never heard before: "Eliminate harm for the people and uphold justice." ”

Listening to a lich say that, why do I have a faint sadness? Lin thought so.
