Zhou Zixiu spoke of the Water Attribute at that moment, and Qin Chuan's attention was more focused than ever, his pen swiftly recording the content being discussed.
But upon hearing "Never underestimate the power of water," Qin Chuan couldn't help but be momentarily lost in thought.
In Zhou Zixiu's description, the power of water was beyond his imagination.
To mix with other substances while maintaining 90% water content, to enhance the inherent power of Water?
This whimsical idea was something Qin Chuan had never considered.
He couldn't help holding his breath while listening even more intently to Zhou Zixiu's subsequent explanation.
"Unlike the Thunder Attribute we just discussed, Water is a substance," Zhou Zixiu smiled. "It, along with the Wood, Earth, and Gold Attributes we will talk about later, is a substance Attribute."
"In physics, there is a formula called the mass-energy equivalence." Zhou Zixiu wrote "E=mc^2" on the blackboard. "A massive amount of energy is contained within mass, and to create one kilogram of substance from nothing requires approximately ninety quintillion joules of energy."
"But lifting one kilogram of substance one meter high only requires about ten joules of energy."
"The difference in energy consumption between the two is a factor of ninety trillion."
"We have to mention the marvel of Extraordinary Energy," Zhou Zixiu smiled. "Based on experimental research, the academicians of Yanhuang Science Academy have proposed a hypothesis about Extraordinary Energy."
"This hypothesis suggests that Extraordinary Energy only translates into substance completely when creating it from nothing. In all other situations, we can only use a minuscule part of it."
"It is precisely this difference that offsets the energy difference of quintillion levels, allowing us to control and create substance Attributes from nothing."
"Even so, creating something from nothing still consumes more power than direct manipulation," Zhou Zixiu paused, "so it's suggested that Transcendents of the substance Attributes carry some of their Attribute substance with them..."
"For example, Water Attribute Transcendents can carry a bottle of water."
Qin Chuan nodded slightly.
In fact, he had noticed this.
With water available, controlling it through the Water Master was easy, but creating water from nothing without water would lead to exhaustion much faster.
"Lastly, let's briefly introduce some common liquids containing more than 90% water content." Zhou Zixiu flipped the PPT to the next page and listed them one by one.
When Zhou Zixiu mentioned "urine," Qin Chuan distinctly felt the particularly plaintive gaze the chubby classmate beside him directed at him.
"What we need to emphasize is this," Zhou Zixiu pointed to the last item listed on the PPT, "plasma."
"Plasma has a water content of 90% to 91%, but it is not blood," Zhou Zixiu paused for a moment. "Blood is made up of plasma and blood cells, with an overall water content of 83%. At this level of water content, the control strength of a Water Attribute Transcendent has already weakened to less than one percent."
"This means that unless the difference in Extraordinary Value between the two sides is a hundredfold, one cannot control the blood to kill the opponent."
"However, the fact that a Water Attribute Extraordinary Value can influence blood is worth researching, and one should be guarded against it when facing Water Attribute Transcendents."
Qin Chuan was visibly moved, quickly taking notes.
He had realized that the Extraordinary Theory Class was far more important than he had imagined.
It was not only about the college entrance examination but also about his own strength.
Observing the thoughtful expressions on the students' faces in the classroom, Zhou Zixiu shifted his tone.
"Next, let's introduce the Ice Attribute..."
-----------------
"Ding ling ling~"
As the end-of-class bell rang, Zhou Zixiu had just finished discussing the last Attribute.
"Class dismissed." As he announced the end of class amidst the students' reluctance to leave, Zhou Zixiu walked up to the chubby classmate with a smile, "Study notes."
"Teacher Zhou..." the chubby student miserably handed over his study notes.
He had never had the habit of taking notes during class, and cramming last-minute was somewhat tough on him.
Fortunately, Zhou Zixiu did not deliberately make it difficult for him, leaving with a comment, "Next time, don't chatter during class," and then turned to Qin Chuan, "Your Contracted Spiritual Beast is Water Attribute, right?"
"Yes," Qin Chuan nodded.
"Perform well in the Extraordinary Practical Combat Class coming up."
With that, Zhou Zixiu, still smiling, turned and left the classroom, leaving Qin Chuan bemused.
Perform what?
"There's only ten minutes for the break; let's hurry to the main field," the chubby classmate put away his notebook and pulled Qin Chuan to his feet. "I feel like if we are late for Extraordinary Practical Combat Class, that Teacher Ji might just chop me down."
"That won't happen," Qin Chuan's mouth twitched, but recalling Ji Huai's entrance yesterday, he also felt some trepidation and quickened his pace.
Before long, all the students from the large classroom arrived at the field for the Extraordinary Practical Combat Class.
In the very center of the field, a figure sat cross-legged on the soft grass, meditating with eyes closed.
It was none other than Ji Huai, who had made a profound impression on the entire senior year the day before.
Now he was dressed in clean practice clothes, but the sharpness and aura of menace approaching him had not decreased one bit.
Without waiting for Ji Huai to speak, students from all four classes quickly formed into four squares, standing in line under the direction of their respective class sports committee members, strikingly straight.
Intimidated by Ji Huai's presence, and even though class had not yet started, everyone stood as straight as if they were in military training.
Soon, the bell for starting class rang.
Ji Huai suddenly opened his eyes.
The floodlights lit up the nighttime field as bright as day, but when the sharp glint passed fleetingly from his eyes, it still rendered the students present almost unable to bear looking directly at him.
"Step forward when your name is called." Without any preamble, Ji Huai's voice sounded.
"Zhu Yuwei."
"Here!"
From the front row of the first class, a striking figure quickly walked forward.
Seeing that the first person called out was the school beauty, students from all four classes immediately began whispering, but these murmurs vanished as soon as Ji Huai scanned the crowd with his gaze.
"Dong Cun."
"Here!"
"Liu Xinran."
"Here!"
One after another, a boy and a girl stepped out from the formation of the fifth class upon being called.
"Qin Chuan."
"Here!" Still observing the first three, Qin Chuan, taken by surprise, quickly walked forward, feeling a mix of tension and curiosity in his heart.
What was the purpose of calling out the four of them?
In the next second, Ji Huai provided the answer.
"Among the students of the four classes, your Extraordinary Values have exceeded 370 during the physical examination."
The physical examination could measure Extraordinary Value?
The students in the four formations showed various reactions.
The students of the third class looked dissatisfied since none from their class was called.
"Report!" Just then, a voice sounded.
It was Zhang Yangwang.
"Teacher Ji, my Contracted Spiritual Beast reached Lv10 last night, and now my Extraordinary Value is also over 370!" Zhang Yangwang spoke with pride, basking in the attention from all around him as he felt this was his moment to shine.
"Then you also step forward."
Ji Huai spoke evenly, a hint of strangeness briefly flickering in the depths of his eyes.
Once Zhang Yangwang stood by the other four, Ji Huai's mouth curled up slightly.
"All of you come at once, and fight me."
