When talking about knowledge about space tension, after discussion, Yang Yuping decided to give a lesson to the military scientific research class to give space tension.

Knowledge can always be transformed into strength, and even on the front line of war, class is still very important.

Admiral Rhodes passed the application for this class and recalled the students from the military research class.

There were 37 trainees in the military scientific research class on the front line, but only 32 were present, and the remaining 5 were allowed to listen to the class online through the communication channel.

This class was arranged in the lab of the Craters.

Before class started, Liu and several other scientific researchers were busy preparing experimental equipment.

Because the time is too fast, even the students' seats are not arranged.

When a military research class student walked into the temporary classroom, Liu pointed outside the door and said, "We can't get busy with our own chairs."

"Do you want help?" Ye Zheyu was the first to arrive and took the initiative to step forward to help.

"No, no, you can find a seat and sit down. Class will start in about half an hour. The professor should be coming soon." Liu pushed his glasses and began to fill a pot with a transparent liquid.

Ten minutes before the class started, 32 students from the military research class arrived, ten minutes in advance, and the time was very accurate.

After all, I am already a military soldier and have developed discipline.

Five minutes left, Yang Yu calmed down his clothes and walked in and started giving a lecture: "Students, I never thought that one day I would teach you all on the front line of the war.

"However, as students of military research classes, we should have an iron will. We are a military research class. We must not only fight for the fate of mankind, but also constantly absorb knowledge for the sake of human scientific research.

"Military and scientific research, this is the real meaning of our class."

Speaking of this, Yang Yuping paused, opened the speech prepared overnight, and entered the topic:

"In today's class, the main content is spatial tension and curvature driving. Research and hypothesis on spatial tension and curvature driving are not available now. Scientists have put forward relevant views as early as the 20th century.

"Why did such a lesson suddenly start with Fang Yuan's newly absorbed superpower characteristics.

"'Super Power Characteristic Evolution', the name of this superpower is still named by me, which happened more than 30 years ago.

"However, unfortunately, the 'superpower characteristic evolution' thirty years ago did not encounter 'lightning speed', so there was no subsequent story.

"After testing the opponent's source, we discovered an interesting phenomenon. After the energy level evolution of the 'lightning speed', a magical power appeared.

"According to Fang Yuan's own description, this magical power will pull him away in front of him.

"According to the normal power engine idea, if you want to gain momentum to move forward, you need to move forward through promotion.

"From the engines of jet aircraft, to the chemical propulsion of rockets, to the ion propulsion... all the power engines currently made by humans are propulsion test engines, and none of them can escape this category.

"And, from the current scientific perspective of human beings, the tension generated out of thin air is a phenomenon that violates science.

"After discussing with several old friends, we thought of a possibility, a possibility that can generate tension.

"If this conjecture can be confirmed, then it can be said that the materials technology I am currently studying will not be worth mentioning in the face of this technology.

“Before talking about curvature drive, we need to talk about what spatial tension is.

"First, let's break the word 'space tension' aside, let's talk about 'tension' first, what is 'tension'."

In such a rigorous science class, Niu Dazhi insisted on being slutty and suddenly said, "A classmate of my junior high school is called Zhang Li."

Most of the military research classes are students, young and lively. When they hear this, they want to laugh, but when they think about how serious this is, they hold it in.

Fang Yuan and his men turned their heads and looked at him, especially Eve, who would have had a fight with him in normal times.

Yang Yuping was very kind and laughed: "Okay, let's take a look at what this thing with the same name and surname as your junior high school classmate?"

At this point, Liu came up with a set of experimental equipment.

This set of experimental instruments is a transparent plastic tray with two coins worth one dollar in the tray and two bottles of transparent liquid next to it.

The one that holds the liquid is a pointed-mouth bottle, which can drip the liquid out drop by drop.

"Let Da Liu do this experiment. If any classmates want to get closer, they can also come up." Yang Yuping signaled Da Liu to start.

Liu took over the conversation and began to say, "Here are two coins worth one dollar, which have been wiped dry and placed flat on the table.

"These two bottles of transparent liquid, one is water and the other is hand sanitizer. I just came upside down from the bathroom sink.

"Now, let's drop water on these two coins and see what happens."

He said, dropping water on two coins.

One drop, two drops, three drops...

Water drops fall on the surface of the coin, but does not flow down the coin, but condenses on the surface of the coin.

As the water drops become more and more, the water droplets gather on the coin, raising up to form a raised arc, covering the upper surface of the coin like a mushroom, but it just doesn't flow down from the coin.

Both coins had seven or eight drops of water, and the same situation occurred. The water was kept on the coins and did not flow down.

"Look at it, according to the common sense of water flowing to the lower part, water droplets should not stay on the coins. Why does this happen? Is this not in line with scientific laws?"

Liu guided everyone to think about the problem, and then continued: "Of course the experiment is not over here. What we need to do next is a set of control experiments.

"I need to drop a drop of hand sanitizer on one of the coins to see what happens."

He said that, and then picked up the bottle containing the hand sanitizer and dripped a drop of hand sanitizer on the coins.

When the hand sanitizer touched the water on the coin, the water on the coin seemed to be pierced and flowed down from the coin in an instant.

On the other side of the coin, the "mushrooms" formed by water droplets are still staying on the coin.

Da Liu continued: "At this point, some students may have to say that maybe a coin can only bear eight drops of water, and one more drop can't stand it.

"If there is no control group, there is really no way to rule out this suspicion. However, this is the rigor of the experiment."

He said, then picked up the bottle of water and continued to drip it onto the second coin.

Nine drops, ten drops, eleven drops...

Until eleven drops, the water on the coins still stopped on it, but the "mushrooms" were getting bigger and bigger.

"Okay, I can only get to this point. If I continue, I really can't hold on."
