Chapter 35 Don't Underestimate the Power of Water

"It's time for class, and there are still a few students who haven't come yet, so we won't wait for them."

"For the content that the late students missed, other students can help them during the break." Zhou Zixiu tapped his watch, "I am a person with a strong sense of time, so I hope that students will not be late again."

"Next, we will start the first class." Zhou Zixiu's eyes swept across the students in the classroom, paused for a moment on Qin Chuan without leaving a trace, and then moved away, "In this class, we will have a preliminary understanding of the theory of supernormal."

"I introduced some yesterday, but that's not all."

"Supernormal theory is an applied science." Zhou Zixiu paused, "Although it is unscientific to classify supernormal as science."

Hearing this, there was laughter in the classroom.

"What is applied science?" Zhou Zixiu knocked on the blackboard and opened the first page of the lecture PPT. "Applied science is a science that starts from practical application and guides the direction of theoretical research by practical needs."

"In short, find problems, solve problems, and study whatever is needed."

"Supernormal theory best reflects this feature." Zhou Zixiu spoke slowly, "Because the classification of supernormal theory research is divided according to attributes."

"Supernormal theory of the gold system with materials science as the main core discipline; supernormal theory of the earth system with geology and civil engineering as the main core disciplines; supernormal theory of the fire system with thermodynamics and chemistry as the main core disciplines, supernormal theory of the wood system with botany as the main core discipline..."

In the midst of everyone's astonishment, Zhou Zixiu listed the core disciplines corresponding to the twelve attributes, and then added, "The main core disciplines are not all, each attribute also involves knowledge of other disciplines."

"Moreover, the requirement for you is not to master one of them." Zhou Zixiu looked at everyone and smiled.

But this smile looked like a devil to everyone.

"You may think that you have mastered the extraordinary power of one attribute, so you only need to learn the corresponding one."

"But this idea is wrong."

"First of all, you will contract other spirit beasts in the future. Don't you contract other attributes? So you naturally need to learn the relevant knowledge of other attributes."

"I think it's good to contract earth spirit beasts in the future." Xiaopang muttered softly, making Qin Chuan's mouth twitch.

In order to learn less, is it okay to contract a single attribute spirit beast?

"Secondly, there is a saying called 'know yourself and know the enemy, and you will never be in danger in a hundred battles.'" Zhou Zixiu glanced at everyone, "Master the knowledge of various attributes, and you will be able to do it with ease when facing opponents of different attributes."

"I am a peace-loving person." Xiaopang muttered again.

"Student, stand up." Zhou Zixiu looked at Xiaopang with a smile, motioning him to stand up, "What attribute?"

"Earth." Xiaopang's head shrank, but he still stood up honestly.

"Very good." Zhou Zixiu nodded, "After this class, I will check your study notes for the other eleven attributes. Sit down now."

Xiao Pang sat down slowly with a look of grief on his face.

Qin Chuan couldn't help but give Xiao Pang a sympathetic look.

"Other students should not whisper to each other." Zhou Zixiu smiled and pointed to his ears, "My ears are very sharp."

"In this class, I will introduce the relevant knowledge of each attribute, about three minutes for each attribute. Starting from the next class, we will learn about the attributes one by one." Zhou Zixiu clicked on the next page of the PPT, "First, let's introduce the thunder system."

"Students whose contracted spirit beasts are thunder systems, raise your hands."

After the voice fell, only seven hands were raised in the large classroom of more than 200 people.

"The lightning beasts have a special activity area, so there are relatively few players who have signed contracts with them." Zhou Zixiu said calmly, "The essence of thunder is electricity. We have learned electricity in junior high school and high school physics."

"As long as there is a potential difference between two points, the charge will move from one end to the other, forming a current."

"If the potential difference between the two points is always positive or negative, then the direction of charge movement remains unchanged, forming direct current."

"If the potential difference between the two points changes rapidly between positive and negative, the direction of charge movement will change accordingly, forming alternating current. "Alternating current is easier to conduct in the human body than direct current, and the damage it causes to the human body is much greater. In other words, it is more powerful." "And the current generated by the power of thunder is all alternating current." "You should have played with rubber ropes, right?" Zhou Zixiu looked at everyone and suddenly smiled, "If you pull the taut rubber rope hard and then let go, it will vibrate up and down continuously." "The extraordinary power of thunder is that hand, which moves the rubber rope called electric potential." As Zhou Zixiu's voice fell, discussions quickly came from the classroom. Qin Chuan's eyes showed a look of surprise.

He originally thought that the Special Affairs Group sent a superhuman to teach superhuman theory, and the teaching level would definitely not be very high, but Zhou Zixiu's easy-to-understand analogy made it easy for him to understand the essence of thunder power.

"Understanding the essence of thunder power, we can start from the perspective of alternating current and consider how to enhance the power of thunder skills and how to control lightning more flexibly, such as..." Zhou Zixiu simply gave a few examples and ended the introduction of thunder.

"Next, let's talk about water." Zhou Zixiu's eyes naturally stayed on Qin Chuan for a while, and then moved away. "From a chemical point of view, water is a liquid substance composed of molecules with the molecular formula of H2O, but this is a single substance of water, that is, pure water."

"The power of water is not limited to pure water."

"Experiments on water superhuman power show that water superhumans have absolute control over liquids with a water content of more than 90%."

"For liquids with a water content of less than 90%, the control of water superhumans will be exponentially weakened as the water content decreases. For every 1% decrease, the control is halved. When it is less than 80%, the water superhuman will have absolute control over liquids with a water content of more than 90%. Control power is negligible. "

"The water content here refers to the mass ratio in the mixture."

"900 grams of pure water and 100 grams of any substance mixed can be controlled by water-based extraordinary people." Zhou Zixiu's voice was a little heavier, "including substances that are insoluble in water."

"Because suspensions can also be controlled by water, it is not difficult to make suspensions of substances that are insoluble in water as long as the particles are reduced. "

"There is an idiom called tenderness like water. We often think that the power of water is weak, but a water knife with added abrasives can easily cut diamonds and high-strength alloys. "

"Don't underestimate the power of water. "
