No one could see how it had taken the scythe out of its empty cloak.

"It's really the Grim Reaper!!"

Some of the team members shouted in horror.

How terrifying and powerful are the magicians here, the legendary master of Hades is actually his gatekeeper!

More than one person thought so in their hearts, and many people's expressions showed fear.

"This scythe...... Seems to be a bit of a problem. ”

Lorraine looked at the scythe.

He always felt that this thing was a bit similar to the farm furniture that farmers used to harvest wheat.

The dull iron exterior and a wooden rod tied to the rough handle make it look like it was casually attached...... How to look at it makes people feel wrong.

But after all, the other party was a strong man who was burned by the flames without any damage, and Lorraine and Agnes were just suspicious in their hearts, and they didn't make a casual move.

At that moment, a sudden gust of wind blew, and the corner of Death's black cloak was lifted, revealing a graceful leg inside.

Hey?

Now many people have seen this scene below:

What's the matter, is this Grim Reaper in front of you a woman?

"I see! She is Hel, the daughter of an evil god and giant, and the goddess of death who rules the underworld! ”

It was Xia who spoke, and I saw her run to the side of the cliff, pointing to the Grim Reaper and saying in shock:

"Legend has it that half of her body is as black as ink, and half of her body is as beautiful as an angel, and what we saw just now should be her beautiful side!"

Hull?

Some knowledgeable mages were suspicious in their hearts:

Who's that?

Are there any similar myths and legends circulating on the mainland? How have I never heard of it.

However, Xia's prestige is quite high now, and the other party is indeed weird and unpredictable, seeing her shocked appearance, many people believe most of them.

"I see, what are you showing up in front of us for?"

Agnes was a staunch supporter of Natsu, and asked aloud to the Grim Reaper.

"Hehehe......"

The Grim Reaper laughed dryly:

"Disturb the human beings who have disturbed the great mage's eternal rest...... Although you have sinned deeply, for the sake of your many trials, I will give you a chance. ”

It waved the scythe in its hand and said in a sympathetic voice:

"As long as you answer my question correctly, I will forgive you for your mistakes and open the entrance to the place where the magician rests!"

Well done, Stephanie!

Seeing the terrible appearance of the "Grim Reaper" in the air, Xia secretly praised her in his heart:

is worthy of an artifact, and the lines made up didn't even say a word.

Thinking of the pain of the two people racking their brains to design the appearance lines, she couldn't help but feel emotional, looked left and right, and found that no one paid attention to her, and came to the edge of the cliff lightly.

Then he hid behind a rock, took off his pants, and crept down.

"What's the problem?"

It was Lorraine who spoke.

"Don't answer it so lightly, maybe it's a trap!"

Agnes looked at the unidentified Grim Reaper in the air, with a cautious expression.

"Listen to my questions, ignorant people."

"Death" said in a low voice:

"Light and darkness, this is a constant topic since ancient times; Now I want to ask you a question about light. ”

It lowered the scythe in its hand to its side:

"All intelligent beings know that where there is darkness there is light, but ...... In that endless dark void, is the speed of light eternal? ”

When this question was asked, the following people looked at each other:

What is it, magical knowledge?

Natural science theories?

"Hey, Merlin, what the hell is this dark mage-like guy talking about, is it the principle of divine magic?"

Johnson asked in a low voice.

"You don't understand that, do you?"

Merlin replied angrily:

"It's about ......"

His mouth opened twice, his eyes kept rolling, and finally he said:

"Actually, it's telling the story between the goddess of light and the dark monarch, you know? That's a big secret......"

"What?"

The other two instantly came to their senses:

"Do these two guys have a leg?"

"Want to know?"

Merlin nodded his head with a mysterious look:

"After returning to the royal capital, how about one holiday villa for one person? Must be in the white area, don't be in the yellow area! ”

"I'm rubbing, you're cheating people......"

The three of them muttered over there.

"There's a concept called 'black holes' in legacy technology."

A mage who had studied the science of ancient relics frowned and said:

According to the above account, this kind of thing, called a black hole, can absorb a qiē object, including light. Since light can be absorbed, does that mean that the speed of light can also change? ”

"I have some knowledge of astrology."

Another mage next to him muttered:

"When the light of the stars is near the sun, it is said that it will be distorted by the attraction of the sun's light and heat, indicating that the speed of light can also be affected; And according to the doctrine of magical matter, if it is assumed that light itself has weight, then it will naturally be pulled by other matter, so that its speed will undoubtedly change. ”

“……”

The two mages looked at each other, then fell silent.

They both felt that each other's theories sounded reasonable, but after all, this kind of doctrine was too cold, and without careful debate and practice, no one knew what the real answer was.

"I've heard a story before."

A goddess sorcerer folded his hands on his chest, as if remembering something, and with a hint of fascination in his voice:

"The stars are alive, and they look at the people on the earth with love in the sky, and once they have an attachment to them, they will burn their own lives and rush to her side with dazzling light; Many stars are far away from us, and before the burning light reaches us, they will die, and all we see is the light of the stars when they were alive. ”

"Ah—what a poignant story, the light of the stars......"

She stood there with her eyes closed, as if in deep intoxication.

“…… Is there any other answer? ”

The Grim Reaper turned his face to look at her, looking a little helpless, and said to everyone:

"Stupid human, you have disappointed me......"

Before it could finish its words, the swordsman of Lorraine suddenly spoke up:

"According to Lordingham's theory of magic, the speed of light should not change."

He took a few steps forward and waved his arm at the Grim Reaper, his eyes blazing:

"Ancient magicians once made a real yàn, they refracted and propagated the light through a prism, ran for months in the vast Nora grasslands, they crossed the swamps, flew over the snowy mountains, and finally measured the approximate speed of the light...... And this speed does not change whether it is in the water or in the air. ”

Speaking of which, he said confidently:

"So my conclusion is that the speed of light doesn't change anywhere."

Seeing Lorraine's eloquent appearance, the others were a little surprised:

Isn't Lorraine a swordsman? When did you start studying the theory of magic, you still seem to be very proficient.

"Unfortunately, your answers are all wrong."

The voice of the Grim Reaper was full of banter, as if to mock the ignorance of the crowd:

"Don't have any other answer? Unfortunately, I will not be able to open the entrance for you, and you will never be able to enter the mage's dwellings! ”

"I'll answer."

Just when despair was evident in everyone's eyes, a voice suddenly sounded.

I saw Xia a little wolf appeared in front of everyone, her face was covered with some black ash, and there was some burnt smell on her body, and her appearance was very different from before.

"Sister Xia, what's wrong with you? Could it be that there are monsters nearby. ”

Agnes flew over worriedly, threw herself into her arms, and reached out to wipe the dust from her face.

"It's okay, I just went around and looked around."

Natsu touched her head, walked up to Death, and said:

"Starlight distorts when it passes near the sun, but it's not that the sun's light and heat attract it, but that photons also have mass, note that this refers to mass, which is a different concept from the weight just mentioned."

She looked at the puzzled crowd and explained:

"A photon, also called a quantum of light, has zero rest mass of the photon, which means that its propagation speed in the void is constant. But this does not mean that the speed of light does not change. ”

She took out a small mirror, and gently bent her black legs, a puff of fire erupted from her round knees.

The flame shines on the mirror, and the flame can be seen clearly from the mirror, taking on a pale color.

"Huh!"

She suddenly threw the mirror straight into the air.

The mirror flew all the way to the black clouds and disappeared inside, and at this time, Xia pulled out the black long knife behind him, and slashed a huge flame knife qi in the air, slashing at the clouds.

"Snort-"

A crack was split in the dense black cloud, and the mirror fell out of it, and the originally dark mirror shone brightly in the air again.

Natsu spread her wings and caught it and put it in the package.

Looking at the mirror that had just disappeared in the black clouds, and thinking about the fire reflected in the mirror just now, Agnes seemed to understand something, and lowered her head in thought.

"The magic theory that Lorraine said is just a vague concept, and the real yàn is not accurate, because the speed of light is very fast, even if the grassland is large, it is impossible to test its actual speed."

Then she looked at them and said:

"There is always a misconception when people look at the stars: no matter how far away they are, they can be spotted as long as they are bright enough. But the fact that photons gradually slow down as they fly, so that the light emitted by any star can only be stored at a certain distance, proves one thing......"

She took a breath, looked up at the Grim Reaper, and said:

"Actually, the speed of light changes."

After speaking, she gave a signal to the other party with extremely vague eyes.

"Smack, smack."

Death clapped his hands and said appreciatively:

"Very well, it seems that there are indeed magicians among you who are not inferior to the wisdom of the master here, who answered my question perfectly, so that you have the qualifications to enter here, I declare ......"

At this moment, the whole mountain suddenly shook violently!

"What's going on, is this here going to collapse?"

Abner sat up from the floor with a sudden "sudden", and the towel on his face fell to the floor.

"Wow! What is this! ”

A thick, round pillar suddenly appeared where Merlin and the three of them were standing, squeezing through the rubble on the ground and slowly rising upward, and the three of them immediately jumped to the side in fright.

"What is this, it looks like a periscope."

Natsu thought of a retro piece of military equipment.

Although she had been mentally prepared, it was the first time she had seen the real thing after all, and she felt a little fresh when she saw this strange pillar folded in three directions.

"Transparent cylindrical passages...... This near-perfect annular shell is a legacy of technology! ”

Lorraine looked at the thick pipe and held her breath: "The inner wall of the passage looks like a very strong translucent material, I don't know what kind of structure is inside." ”

"Ahem."

The Grim Reaper coughed:

“…… I announce that you have officially been admitted! We look forward to you becoming the future pillars of this continent......"

After a few dry, nourishing words, the Grim Reaper slowly fell into the purple flames below.

"What a strange Grim Reaper."

Agnes muttered as she watched from the air where it had disappeared.

"This thing stopped."

In front of Merlin, the transparent passage suddenly stopped rising.

"Buzz ......"

Then a low roar sounded, and a huge stone plate slowly floated from the bottom of the passage, hanging in front of everyone's eyes.

"It's a passage device."

Lorraine looked at the stone plate in front of him, and reached out to touch the cold outer wall of the pipe: "It is also a tool specially used to carry guests, I have seen similar devices in some ruins, but it is far less sophisticated than here." ”

"Lorraine, you seem to be very good at magic."

Agnes looked at him a little depressed.

Although she herself is a master of magic, she doesn't know anything about the previous theory of light and the legacy technology in front of her, and Lorraine, a swordsman, actually understands these things, which makes her a little unhappy.

"Hehe, but you still don't know as much as my sister Xia, but she answered the Grim Reaper's question correctly."

Agnes coquettishly flew onto Natsu's back and lay on her shoulder, with a happy face.

"Alright, little love, it's time for us to go."

Natsu patted her on the back and led her to the huge stone plate, and then walked up,

Then he turned to everyone and said:

"After several days of difficult journey, we finally got through guò to the final test! Now, please join me in the most mysterious place on this island, the abode of the great magicians, and the sleeping place of ancient magical science! ”

……

"It's scary down here."

Blackened by the edge of the stone plate, Abner looked at the sea of flames below and said:

"We're not going to fall, are we?"

"No, it won't."

Lorraine looked at the orange-yellow outer walls of the passage around her and said:

"This is the passage of light mentioned in many records, and it has a magic defense comparable to that of a mage on the outside, which can protect the people inside from any damage, and it is a very powerful legacy technology."

"Look, we're going to start going up!"

A goddess sorcerer covered his mouth with his hands, looking at the passage in front of him that gradually penetrated into the black clouds, his face was frightened and a little curious.

"Sunshine!"

Hamdo suddenly jumped up from the stone plate, pointed to the sky and shouted, "That's the sun!" Sun! After coming to this hellish place for so long, I finally saw the sun! ”

He cried and laughed, patting Johnson the shoulder, grinning at the latter.

I saw a golden sun jumping out of the clouds, shining on the white sky, and the endless clouds reflected a dazzling light, which made people involuntarily squint.

The bright sun emitted infinite light and heat, shining into the orange channel, shining on people's faces, illuminating their hearts, and swallowing away the gloom in everyone's hearts.

-- Everyone's faces are filled with hope. R1152
