Blue Sword

Mia opened her eyes and saw herself sitting in a room.

The room is airtight, and all the corners are filled in. It looks like a stupid old-time practice to remove mold in the corners.

The professor sat cross-legged on the ground in the center of the room, with three students, including Mia, surrounding him. Two men and two women were seriously discussing unclear academic issues with the professor.

And, everyone has shaved heads, and five big light bulbs are shining in the room.

"The important thing is to eliminate the horns." The professor continued, "Those hounds are not high-dimensional creatures. In fact, they live in fragments of dimensions."

"What are dimensional fragments? First of all, you need to understand the concepts of 'continuous' and 'discrete'." The professor picked up a male student and asked, "John, let me ask you."

"How many non-overlapping points are there on a straight line?"

"Uh." The male student was obviously stunned for a moment, "Countless?"

"That's right." The professor said, "Another example: now it is not a straight line, but a line segment with both ends closed and 1cm long. How many non-overlapping points are there on the line segment?"

"Still countless." Another female student named Mary replied.

"Yes." The professor smiled, "That's what continuity means."

"A continuous world means infinite possibilities. A continuous three-dimensional world can accommodate an infinite number of two-dimensional surfaces; a continuous two-dimensional surface can accommodate an infinite number of one-dimensional lines. And discrete..."

He shrugged. “As an antonym to continuous, ‘discrete’ is not so nice.”

"In the discrete world, space and time are isolated. How many points are there on a discrete straight line? Finite. Even in our definition, a straight line in the discrete world cannot be called a straight line, but should be called 'a large number of points' A collection of linear arrangements."

Mia:? ? ? ? ? ? ? ? ? ? ? ? ?

"Milia." The professor cast his gaze on her, "Do you have any questions?"

"I..." Mia opened her mouth and said in frustration, "I have no doubts."

In fact, she didn't understand a word of it. So let alone questions, she didn't even know how to ask questions.

"Professor, your remarks remind me of the wave-particle duality." The male student named John said fawningly, "In the microscopic world, they exhibit discrete, particle characteristics; in the macroscopic state, they exhibit continuous, wavelike characteristics. Characteristics."

"This is the contradiction in our world." The professor nodded and said, "As for the original composition of the world, some people advocate 'string theory', saying that all particles are composed of closed and curled strings. This is an obvious view. The philosophical thinking that 'continuous' is greater than 'discrete'..."

Everyone was chatting excitedly there, but Mia's little head soon drooped, and she almost fell asleep after listening to it.

Outside the screen, everyone was speechless as they looked at the sleepy Mia. Bishop Chino in the monitoring room looked serious, but he was actually laughing proudly in his heart.

Sure enough, choosing peaceful mode is right. For these mercenaries, no matter how fierce and dangerous the battle is, it is far less torturous than academic theories that require brain use, hahahahahahaha.

"That's it," the professor concluded. "I must emphasize it again."

"These hounds live in discrete time and space. In order for them to come to our world, they must pass through anything smaller than an angle of 120 degrees."

"The shape of an object affects the distribution of its gravitational field. Rotate the 120-degree angle around its angular bisector and we get a cone. This cone, and cones sharper than it, produce holes in the gravitational field - let The holes that the hounds were able to slip through and descend upon our world.”

"So, before we encounter a hound, we have to make sure we eliminate all angles around it that are less than 120 degrees...and if that doesn't work, seal it off."

"Yeah." Mia nodded casually along with the movements of other students.

"Now, let's put on gloves and braces and eliminate the sharp angles of our fingernails and teeth," the professor said.

Everyone followed the professor and put on special gloves and braces.

"Then there are special inflatable protective suits." The professor said.

Everyone then put on bulky protective clothing. This clothing was made of special materials without any gaps or wrinkles. After wearing it, it looked like a silly Kumamon stuffed animal.

"Hahahaha!" Looking at the stupid costumes of everyone around her, Mia couldn't help laughing, "What the hell is this look!"

professor:………………

Other students:……………………

"Milia, you seem to be particularly...excited today." The professor considered his words.

"Professor Pnin, Milia is just stupid again." The female student named Maria said, "She was sleeping while you were teaching just now."

"What did you say?" Mia was furious, "I didn't sleep! I was just... I was just thinking about what the professor said!"

"Oh, do you need to close your eyes when thinking?" Maria said sarcastically.

"Haha." Mia sneered unhappily, "Did you know? In horror movies, your character is the first female supporting character to die after encountering a monster!"

Maria:………………

"Milia!" Others complained, "Don't say such unlucky words, we have to explore the fourth dimension next!"

Seeing someone helping her, Maria hugged her arms and sobbed aggrievedly:

"I feel uncomfortable... Her curse just now made me a little uncomfortable... I want to take a leave of absence temporarily this time."

The professor could only reprimand Milia sternly, and then he and others comforted Maria for a while, finally coaxing the female student to recover.

"Everyone, take it." As if he was afraid that she would regret it, the professor quickly took out a few pills and distributed them to everyone.

"What is this?" Mia asked.

"Some kind of psychotropic drug." The boy named Joshua next to him said, "It can help us empty our brains, allow our consciousness to enter the four-dimensional space, and explore a new mysterious world... It is said that I, the philosopher of the Dragon Kingdom, After taking this medicine, I later wrote the Tao Te Ching.”

Mia:? ? ?

She still didn't understand a word of Joshua's explanation. The only thing I knew was that the pill was some kind of "psychotropic drug."

Little Mia suddenly remembered something. When the team first arrived in Solomon City, Asik once told everyone that they could shop and have fun in Solomon City, but don't touch "drugs."

Don't touch any drugs. This is the iron rule set by Aske. Anyone who dared to violate the rules would be beaten out of her stomach by Aske, including the medicine she had taken and the previous few meals.

Thinking that Ask was staring at her from the screen outside, Mia immediately shuddered and quietly held the pill between her fingers.

"After taking the drug, our consciousness will travel through the long river of time." The professor's expression gradually became serious and serious, with some kind of contagious faint enthusiasm and excitement, "Ancient Greece, ancient Rome, Homo sapiens, Nian Detes, apes and dinosaurs, all things in history, past and future, are unfolding before our eyes!"

"Next, I will turn on the recorder. When you are swimming, you must remember to describe what you see, so that when we leave the four-dimensional space, this precious information will not be lost from our minds. .”

"And..." His voice suddenly revealed a hint of fear, "Be careful of the 'hounds' in the broken space.
