Human Energy

"Big Head must be piecing together some messy nonsense in his brain right now. During class just now, I clearly saw him looking like a complete moron—eyes half-closed, a lecherous, silly grin on his face, and drool almost dripping out. He looked like a sleepwalker; he didn't take in much of what Teacher Daina said at all!" Light whispered to Doug nearby, only shutting his mouth after Barry gave him a gentle kick. Barry didn't know that Light's guess at this moment was actually the truth.

"Last night at home, I was boiling water. After it boiled, I took the kettle off the stove and put it on the floor, forgetting to pour it into a thermos. When I remembered and went to pour it, I found the water in the kettle had already gone cold..." The other animals stared at Zhang Tie with eyes as wide as ox testicles, having no idea what this messy nonsense was supposed to mean. Fortunately, discipline was at its best during Teacher Daina's class; had it been any other, Zhang Tie might have been drowned in rotten eggs thrown from below the moment he finished his opening line.

Teacher Daina listened patiently without rushing him, which gave Zhang Tie more time to organize his thoughts.

"I didn't pay much attention to it at the time and just boiled the water again. But later, when I was going to sleep, I thought about it and came up with a question I couldn't understand. So, I decided to take this opportunity to ask Teacher Daina today: Are we, as human beings, like a boiling kettle from the moment we are born, unknowingly losing our body's energy every single moment of every day?"

This question was very novel and unexpected. Even Light and the others were somewhat moved upon hearing it. They hadn't expected Zhang Tie to actually ask such a high-level question while rambling—is everyone, in fact, that boiling kettle?

This question stemmed from the information Zhang Tie saw when generating the "Flawless Fruit." He had never quite understood it, so he took this opportunity to bring it up and ask Teacher Daina.

"This student has great insight, and this question is quite unique. This semester is everyone's last in school. In my original lesson plan, I intended to discuss this issue of body energy with you all later on. I didn't expect this student to have already discovered it, so I will bring this topic forward and explain it to everyone now..."

"Ding-a-ling..."

Just as Teacher Daina was about to speak, the bell for the end of class rang. She paused for a moment, waited for the ringing to stop, and then smiled apologetically. "Let's end class here for now. Everyone take a break. It will take a lot of time to explain this clearly, so we will discuss this in the next lesson..."

Class was over. A few people walked out of the classroom, but most lingered. The bolder ones found various excuses and reasons to crowd around Teacher Daina, deliberately asking stupid questions related to the biology lesson she had just taught. Teacher Daina answered them patiently, seemingly unaware of these animals' ulterior motives. Gelis and his three lackeys were particularly conspicuous; they practically surrounded Teacher Daina. Gelis spoke loudly, laughing exaggeratedly from time to time to show how familiar he was with her, putting on a show of having a pleasant conversation. Then, whenever Teacher Daina wasn't looking, he would turn to the others in the classroom with a smug, show-off expression.

"Gelis is an idiot!" Sista muttered quietly to the side. "If his old man didn't have some connections and a better family background, and if he and Baghdad were on the same starting line, Baghdad would absolutely beat him until he couldn't find his teeth. It wouldn't be his turn to show off here!"

These words hit the spot for Baghdad. He snorted heavily through his nose, staring fixedly at Gelis. Everyone in the Airplane Brotherhood knew that Gelis was the target Baghdad had set for himself to surpass in this life.

"I heard the final recommendation list will be finalized at the end of this semester. Gelis wants to get a recommendation spot to enter the Alliance's Officer Training Academy. He needs to have a sufficiently dazzling performance right now. A Level 2 Battle Soldier qualification might make him a big shot in our school, but it's nothing on the outside. I heard the Alliance's Officer Training Academy's minimum standard for recruiting apprentices in Black Flame City these past two years is a Level 3 Battle Soldier. Gelis is still a bit short, after all. A Level 2 Battle Soldier wanting to enter the Alliance's Officer Training Academy is still a toss-up!" Light added from the side.

"Even if he can't get in, Gelis is already very impressive!" Shavin said enviously.

"Shavin, the Alliance's Officer Training Academy is impressive for ordinary people, but it's not the most impressive. Our Andaman Alliance is just a small force in the Blakerson Human Corridor that can barely protect itself, and we aren't known for our martial strength. Although the Alliance's Officer Training Academy is a relatively high-level institution within the Alliance, it's really nothing to brag about outside. Those truly gifted geniuses, like our former senior Li Shizhen, were reportedly handpicked and taken away by an elder of the Alchemist Guild to become a secret apprentice to the guild elder, soaring to the sky. That is the most impressive thing—a million times better than Gelis. Never mind Gelis, even his old man is just scum in front of them!" Barry patted Shavin on the shoulder and said in an old-fashioned tone.

"I heard alchemists make a lot of money?" Zhang Tie was interested in any high-paying profession, so as soon as he heard Barry mention alchemists, he thought of money and gold coins.

"There are only four alchemists in the entire Black Flame City. Three are resident consultants for the three major Battle Halls of Black Flame City, and one is a patron of the Coal and Steel Union. You tell me if it's profitable? There are only a handful of professions in the entire continent that make more money than alchemists..."

"I wish I could become an alchemist!" the simple-minded Doug said honestly from the side.

As soon as Doug spoke, everyone went silent. They turned their heads to look at him seriously. Doug put on an arrogant look. After a long while, Barry patted Doug on the shoulder. "Doug, I never realized it before, but you're so humorous!"

The ten-minute break passed quickly. The last class of the morning arrived, and the animals in the classroom sat down with their hands on their desks. Without any preamble, Teacher Daina began drawing on the blackboard with chalk. Within a few minutes, an image of an old tree wrapped in countless vines appeared. No one understood what it was. After finishing the drawing, Teacher Daina put down the chalk, clapped her hands, and turned around.

"In the last lesson, that student asked if our bodies are losing energy at all times. I will use a human physiological anatomy diagram to start this topic. This diagram shows the urinary tract and blood vessels near the human bladder. That old tree-like thing on the blackboard is the urinary tract at the bladder position. The vine-like things wrapped around it are tiny blood vessels. These vessels act like tree roots, re-extracting beneficial trace elements and energy from human urine back into the body to prevent these beneficial elements from being wasted. The development of anatomy provides a tool for everyone to understand the mysteries of their own bodies, but the understanding this tool can provide is limited because our body is the most precise instrument in the world. The many mysteries of this machine cannot be explained by simple anatomy. In fact, even though our bodies have countless complex systems and functions to prevent energy waste, we are still wasting huge amounts of energy every moment. Take urine as an example: just as you learned in Survival Class, in some cold, desperate situations, holding your urine can allow you to persist for more than 5 hours longer than others. And when you cannot obtain food or water, collecting and drinking your own urine can allow you to persist for another 48 hours. Why can a bladder of urine sometimes be a matter of life and death? It is because urine contains huge amounts of body energy and beneficial substances. This energy should have remained in the body, but it was lost for no reason. Our bodies have taken many measures to prevent this loss, but they only have a small effect. More body energy is lost through various channels for no reason. I know that among some special groups, there are people who regard their own urine as a medicine that can strengthen the body and prolong life. The first thing these people do when they wake up in the morning is to urinate, then collect and drink it, because they believe that this method can prevent the loss of energy and beneficial substances in their bodies..."

This kind of thing sounded even more terrifying than the "Blood Clan." The animals in the classroom were stunned, especially since "drinking urine" was coming from Teacher Daina's mouth. That strange sense of excitement stimulated the animals so much they almost wanted to howl at the sky.

"Teacher Daina, are there really people who drink urine?" an animal in the front row couldn't help but ask loudly.

"Yes!" Teacher Daina's expression was very serious, without any embarrassment. In her eyes, this seemed to be a purely "academic" question. "Those people only drink the urine from their first urination in the morning. They believe the energy in the urine can keep them young and healthy. In fact, this group of people are all famous for their longevity. They also regard the urine of children and infants as a panacea, believing that it contains the purest life energy!"

The classroom became even more agitated.

"I used the example of urine just to explain to you that our bodies waste a lot of energy for no reason in daily life. No one knows exactly how much this wasted energy amounts to. I only know that if a person could collect even a small fraction of the energy the body wastes every day, it would be a huge number. Besides urine, our bodies have other channels that waste even more energy!"

"What channels, Teacher Daina?"

"Wet dreams and masturbation!" Teacher Daina's expression was serious and calm, but when these two words came out of her mouth, the classroom fell into a strange silence again. The animals looked left and right, their expressions incredibly weird. Some lowered their heads, not daring to look at her. Zhang Tie looked at the animals of the Airplane Brotherhood beside him and found that their expressions were also quite spectacular.

This time no one spoke. After looking around the classroom, Teacher Daina continued on her own. "Every male sperm, when combined with a female egg, can create and nurture a great life. Every sperm contains a great life miracle waiting to descend. Have you ever thought about the reason behind this? It is because every sperm contains huge life energy. A mature woman can only produce one egg a month, while an adult male can produce hundreds of millions of sperm every day—that is, hundreds of millions of life miracles. Do you know how powerful the life energy in these hundreds of millions of sperm is? You don't know, and neither do I. I only know that in the ancient East, for tens of thousands of years, those practitioners known as Qi Practitioners have regarded the life energy that produces sperm in their bodies as a treasure that can elevate their lives and bodies to a higher level. Except for procreation, they would not easily let their sperm flow out of the body and be wasted in vain. Another kind of waste that everyone doesn't know about is the countless distracting thoughts surging in our brains every moment. These countless thoughts consume huge amounts of mental energy every second. In our era, in places beyond your imagination, there are powerful practitioners and warriors who, relying on self-discipline and certain powerful secret cultivation methods, convert this huge life energy and mental energy produced by the body to ignite the Bright Points of the body and break through one cultivation barrier after another, eventually becoming powerful warriors and guardians of the human race that people look up to. All paths of the strong are incompatible with indulgence..." Looking at the students deep in thought, a beautiful, spring-like smile appeared on Teacher Daina's face. "Do you know what Teacher Daina's greatest wish is?"

The animals in the classroom looked at Teacher Daina in astonishment. Zhang Tie's eyes flickered slightly, not knowing what he was thinking.

Amidst the anticipation of the animals, Teacher Daina said something that could change their outlook on life and the world.

"Teacher Daina's greatest wish in this life is to see one of my students become a powerful warrior or a guardian of the human race. Then I can dress up beautifully and marry him. Unfortunately, until now, Teacher Daina has not met anyone I could marry. So, Teacher Daina asks you for one thing, to make a promise..." The smile full of a mature woman's charm and her twinkling beautiful eyes left the animals stunned. They looked at Teacher Daina, who was radiating astonishing beauty at this moment, unable to speak, but they hadn't expected even more astonishing words to come from her.

"Teacher Daina's promise to you is: when you are strong enough, strong enough to protect Teacher Daina, will you let Teacher Daina marry you?"

Will you let Teacher Daina marry you...

Will you let Teacher Daina marry you...

Will you let Teacher Daina marry you...

A voice roared in the brains of all the animals. They couldn't believe what they were hearing. Boom, the classroom exploded...

"Are you willing to make such a promise with Teacher Daina?"

"We are!" The animals' unified roar almost shattered the classroom windows.

"Very well, our promise is made. You are all men now. A woman's youth is precious; Teacher Daina cannot wait for you forever. So, the content of this promise is: if any of you can be the first to obtain the Blood Scorpion Warrior rank badge before the age of 20, Teacher Daina will marry that person!"

"Yes!"

At this moment, the animals could not understand that there is a lie called love in this world, which can weave the most beautiful blessings and expectations, and can become the greatest spur and strength on a person's path of growth. At this moment, all the animals had red eyes, looking at Teacher Daina, panting, feeling their big heads and little heads swelling at the same time.

Zhang Tie also lost his composure at this moment. There was only one voice roaring in his head—before the age of 20, get the Blood Scorpion Warrior rank badge...
