As the minutes ticked by, the sky grew brighter.

At sunrise, the morning sun looks particularly heavy, the floating corpses in the Hawaiian sea fill the sea, and the sky is full of endless unknown creatures, which makes people feel chills at the bottom of their hearts.

How people on Earth wish it was just a nightmare, that when they wake up, the world will be back to the prosperity it was a year ago.

……

Pei Min focused on perceiving the giant sword in front of him, and he couldn't pull it out with his own strength. If this sword was made of iron, he believed that he could pull it out, but this sword was like matter and pure energy, and Pei Min really didn't know where to start.

It's like letting a mortal lift a tall building, and Pei Min also feels powerless in the face of this sword.

What made Pei Min feel even more aggrieved was that he always felt that what he touched was only the "shadow" of the sword, but he didn't know where the real body of the sword was. How can you pull out the "shadow" yourself?

Distracted glance at the area where he was standing, a flat ground seven kilometers in diameter, with strange patterns printed on the ground, and none of the YSA troops dared to approach this area, and they had even retreated far away, emptying the entire island of Hawaii.

"Tsk, tsk, tsk...... You are so powerful that even the people of the heavenly realm will fear you. Pei Min smiled playfully at the giant sword, and then his expression became a little more serious, "You must think that I might pull you out, so you came to test me." Oh, you are a sword, and the old man also thinks that there is no sword in the world that the old man can't pull out. ”

Pei Min's eyes sank, and he put his hands on the giant sword to feel it carefully.

***

In the refugee city, everyone was shocked by the giant sword, but Fang Qi in the room was extremely curious about this unknown thing.

Pei Min is fearless in his heart, invincible in his mentality, and is not affected by the giant sword. And Fang Qi saw that the giant sword was also fearless, his heart was full of thirst, a scholar's thirst for the unknown.

Seeing the giant sword, Fang Qi's mood was excited, he wanted to know all the parameters of this giant sword, this was an existence that even the Youth League would fear.

After tapping at the computer screen for a while, the look of surprise on Fang Qi's face became more and more intense. In the end, he couldn't help but shout, and the face on his face trembled with excitement.

"Oh my God, oh my God, oh my God......"

Fang Qi grabbed his hair and stared at a few pictures on the screen, with only four words written on his face, "Unbelievable".

Yuwen Zhi and Ji Tianci both looked at Fang Qi in surprise, first, they were surprised that Fang Qi was not intimidated by the Heavenly Dao, and second, they were surprised that Fang Qi seemed to have discovered something.

Both asked at the same time, "What did you find?"

Fang Qi's right hand couldn't help but tremble and pointed at the computer screen, "You, you, you see...... As soon as the greatsword appeared, my drone measured its energy readings from a distance and drew a model of the data sent back, with the leftmost 'Model One' being the original appearance of the greatsword. The energy contained in it has exceeded the maximum measurement value of the drone, so its energy value will not be displayed here, but I have simulated its 'appearance' based on the characteristics of the effect of energy on space. ”

Yu Wenzhi and Ji Tianci looked at "Model One" at the same time, it was basically a giant sword, and I didn't know that I thought it was a building structure drawing.

"If you look at the next three models, I couldn't draw the model at first because there were obvious errors in the data. I can't put them together to make a complete model because I don't know if the data is correct.

Then I thought, what if all this data is correct? If I can't fit multiple data in the same location, then I'll create a new coordinate system. ”

"A new coordinate system?"

"Yes, if we don't count time, the space we exist in is a space with a three-dimensional coordinate system, and if there is data that cannot fit in the three-dimensional coordinate system, then I will put it in the fourth dimension. ”

Ji Tianci and Yuwen Zhi didn't reply after listening, because they didn't know how to reply, and they didn't even know where to ask.

Fang Qi patted his head and took a piece of paper and an ornament glass ball, "This is actually a very simple thing, the piece of paper is regarded as a two-dimensional coordinate system, and this glass ball exists in three-dimensional space, we can't put this glass ball in a two-dimensional piece of paper." In the same way, what if the greatsword exists in a four-dimensional space? We also can't describe things in a four-dimensional space in a three-dimensional coordinate system. ”

Fang Qi hurriedly beat the drum on the keyboard again, "Come, you see, I found out the rules according to the data collected during the initial form of the giant sword, established a mathematical formula, and then rearranged and combined the messy data according to this formula. And guess what?"

Speaking of this, Fang Qi slapped the table again, thinking that it would scare the two people in front of him, but the two of them just became more focused, without the slightest sign of being frightened.

"My conjecture was correct! I was correct! The data in the fourth dimension was exactly the result of the formula, so I plotted 'Model 2'. Look!"

Yu Wenzhi and Ji Tianci looked at the picture on the computer marked "Model 2" with strange faces, it was a dazzling picture, made up of countless lines, but its structure was too complicated, and it was impossible to tell what pattern these lines were combined.

"Did you see, did you see?" Fang Qi looked very excited.

"No...... What is this?"

Fang Qi was angry, angry that the other party couldn't share the joy in his heart with him, "You guys are really ...... It's still extraordinary, and there's no imagination at all. This is a perspective view of a four-dimensional space, and the Greatsword has changed for the first time. ”

"Then why do we only see that the giant sword has become a little smaller?" Ji Tianci asked again.

"What a stupidity!"

Fang Qi finally couldn't help but take a sip, and Yuwen Zhi on the side hurriedly coughed a few times to hide his embarrassment.

"A drop of blood on this piece of paper. Fang Qi held a piece of paper in both hands and said to the two.

Yuwen Zhi did not hesitate, and a drop of blood dripped from his fingertips and fell on the piece of paper. His blood was also strange, more crimson in color, and a circle the size of an inch was printed on the paper.

"I understand no, if we live in the two-dimensional paper world, the puddle of blood we see is so big, and this puddle of blood returns to the original three-dimensional droplet shape, and we can only see one aspect of it from the two-dimensional world, so we will feel that it has become much smaller. It's the same with the greatsword, which goes up from three dimensions to four dimensions, and it 'stacks' on top of each other, and when we look at it from the three-dimensional world, we only see it getting smaller. ”

Ji Tianci's eyes widened, "So that's the case!"

Yuwen Zhi also said quietly: "Actually, you can also explain it to us with a drop of ink......

This is to make your understanding more profound. The original form of the sword you can imagine as a flat square, it changes once, and the square seems to be folded, folded into a six-sided cube, and only one side of it can be observed in our world, so visually it becomes much smaller. This change has gone beyond the rules of space, and I don't know what it has become, I just simulated and drew its form, and I don't even know if it is an energy or a substance.

The two subsequent changes of the giant sword have risen from the four-dimensional space to the five-dimensional space and the six-dimensional space, and I also don't know what form the high-latitude space exists, they may be the so-called chaotic space. ”

Yuwen Zhi shook his head when he heard this, "This is not the case in Chaos. The dimensions in the chaos are chaotic, not only the spatial dimension is chaotic, but also the time dimension is chaotic. We live in a stable spatial dimension, but we don't know whether this stable form is naturally formed or artificial. ”

"Artificial?"

"Well, I'm not sure either. Chaos is the unordered, irregular, and unregulated universe before the dawn of the universe. Perhaps it was the true gods who established stable worlds in the chaos and set the rules, and the challenge Pei Min faced at this time was the challenge of breaking the rules. ”
