Ye Zheyu and beef balls began to dig trenches, as a physical training, and the training intensity was much lower than the bench press.

"You say, will the captain choose us?" Ye Zheyu leaned over to the beef balls and asked in a low voice.

"Of course, why would you bring us here for camping?" Beef Balls replied as a matter of course.

"What if I eat a casual meal?"

"Won't it?"

"Really, won't?"

"......" Beef Balls started to get a little nervous.

"Han Youwei must be stable, I heard two days ago that the star power level is already level 4. Surely every team wants to grab. Ye Zhiyu continued to hoe.

The beef balls stopped, held the hoe, thought for a while with a serious expression, and suddenly laughed again:

"If it's a substitution, Eve must be replaced first."

"That's not necessarily, Eve's ability is strategic, and her parents are Starenergy Technology weapon researchers invited back from Europe by the country, and she can bring any equipment with her in this rift battle, and Eve will definitely be armed to the teeth." Ye Zheyu said.

Beef Ball suddenly found that his position was a little unstable, looked at Ye Zhiyu, and asked, "What is your star power level now?" ”

"Level 3." Ye Zhiyu replied.

"What's the matter with level 3? Wasn't it level 2 last time? Beef balls widened their eyes.

"After I used the Star Power Injection, I was upgraded to Level 3." Ye Zheyu explained.

At the beginning, he was still hesitant to use Xingli Injection, after all, something worth a million could immediately improve the situation at home if he sold it.

Later, after accepting the supernumerary work of the Supermanagement Bureau, he made a decision and used the E-type star power injection.

"Otherwise, when you're going to eat barbecue, you can ask Fang Yuan and see what he means." Beef Maruk egged.

"I don't ask, anyway, I tried my best, whether I can participate in this actual battle, I can accept it."

Ye Zheyu made up his mind, if he couldn't participate in this rift battle, it didn't matter.

Working well in the Super Management Bureau also has a way out.

……

Fang Xiaozhuzi carefully helped Xiong Ba clean the hair, black and white, and the fur was shiny.

When eating barbecue.

A group of people began to feed Xiong Ba's mouth, grabbing everything and stuffing it into Xiong Ba's mouth, and they never got tired of it.

Xiong Ba is like a combine harvester, he can chew and swallow everything.

"Don't feed it, if you feed Xiong Ba again, you'll have a bad stomach!" Fang Xiaozhu snorted angrily and stopped, then grabbed a sugar cane and stuffed it into Xiong Ba's mouth.

"You're the one who feeds the most." Fang Yuan stretched out his hand and knocked her brain.

After you have eaten and drunk to your heart's content.

The team of five gathered in the living room and began to discuss the rift actual battle.

Fang Xiaozhu used Xiong Ba as a cushion, leaned on snacks, ate a bite by himself, and then stuffed a bite into the panda's mouth.

"What the hell is a spatial rift?" Beef balls usually have poor grades in cultural classes, and they don't know what the spatial rift is.

However, several high school culture classes did not explain in detail the nature of the spatial rift.

Han Youwei looked at everyone and said with a smile: "There is a book in this library that has been explained, Fang Yuan, why don't you tell them." ”

"Okay."

Fang Yuan took a piece of paper, drew two dots on the paper with a pen, marked A and B respectively, and then began to explain:

"Suppose this piece of paper is a two-dimensional world, what is the distance between point A and point B?"

"It's not simple, draw a straight line through two points, and the straight line is the distance. This elementary school student understands everything. Beef Balls felt that this question was too simple, and immediately rushed to answer.

Fang Yuan draws a straight line, connects two points, and then marks the distance of one light year on the straight line: "Okay, let's assume that the distance between the two points is one light year, that is, in this two-dimensional world, it takes a year to move from point A to point B at the speed of light. ”

After the assumptions are finished.

Fang Yuan picked up the paper, folded the paper, just so that point A and point B coincided, and then explained:

"Now that the paper is folded, point A and point B coincide, so what is the distance between these two points?"

"It's zero. It's all overlapping. Beef Balls replied as a matter of course.

Fang Yuan glanced at Han Youwei and asked her to help answer.

"The correct answer is that in a two-dimensional world, the distance between the two points is still one light year, but in the three-dimensional world, the distance between the two points is zero," Han explains. ”

Ye Zheyu suddenly understood, and suddenly realized: "So that's the case, because the two-dimensional world only has the X and Y axes, not the Z axis. So, in a two-dimensional world, points A and B are still one light-year away from each other on the xy plane. But in the three-dimensional world, with the z-axis, the distance between points A and B is zero on the z-axis. ”

Fang Yuan then explained: "This is to deduce the three-dimensional world from the two-dimensional world. We live in a three-dimensional world and can't see the fourth dimension. Our three-dimensional world is like a three-dimensional piece of paper, the earth is point A, and the rift world is point B.

"Now, this piece of paper is a two-dimensional world, folded in a third dimension. And what happens to our three-dimensional world if it is folded in the fourth dimension?

"That's right, our three-dimensional world, folded in the fourth dimension, causes the Earth and the rift world to overlap like two points AB, and there is a collision.

"Two three-dimensional worlds collide in the fourth dimension, thus creating a spatial rift."

This explanation explains the cause of the spatial rift through a piece of paper, which is very easy to understand.

"I see." Eve understood, and nodded.

"So, if you pass through the spatial rift, you can go to another three-dimensional world?" Beef Balls began to imagine what it would be like to go to another world.

"Yes, you can go to the world of Star Beasts, and once the spatial rift is closed. Just like this piece of paper, when it is re-unfolded, the distance between those two points becomes a light year again. When the time comes, if you want to return to Earth, you can only rely on dreams. Fang Yuan replied.

Beef Balls then asked, "Fang Yuan, have you decided on the team list?" ”

"Not yet."

"You're not going to change people, are you?"

"I haven't thought about it yet."

Fang Yuan said, and after thinking seriously for a moment, he said, "Before I decide on the team list, you have to think clearly about whether you are really ready to participate. This rift actual battle is not an assessment, but a real rift war.

"I even suspect that the military may have predicted some huge crisis and needed to cultivate powerful awakened people, so the military arranged actual combat assessments."

"What great crisis?"

"I don't know. However, when I was explaining the nature of the spatial rift just now, I thought of a possibility......"

Fang Yuan paused, and then said, "Maybe the collision between the Earth and the Star Beast World in the fourth dimension is getting more and more intense. In that case, spatial rifts will appear more and more, and even in the end, some of the two worlds may overlap. When the time comes, the apocalyptic world will come. Perhaps, at one point, we have to live by picking up bottle caps. ”
