Bai Zhenzhen asked, “Has your Myriad Law University not taught you any battlefield first aid knowledge?”

Zhang Yu was surprised to hear this, then said enviously, “You have first aid classes?”

Bai Zhenzhen replied, “Perhaps it’s because major insurance companies currently refuse to insure our department.”

“Seriously, I’ll just project myself over there. Give me full-view access, then follow my movements.”

With a flash, Bai Zhenzhen’s figure projected itself in front of Zhang Yu.

As full-view access was granted, Bai Zhenzhen appeared in the dorm room as if she were physically there.

She squatted beside Le Mulan and said to Zhang Yu, “Extend your hand and follow my movements…”

Zhang Yu’s hands overlapped with Bai Zhenzhen’s projected hands, gently sweeping over Le Mulan’s lower abdomen to check for injuries.

A moment later, Bai Zhenzhen nodded slightly and said, “It’s alright, no major issues, just a little internal organ damage.”

“It’s a minor problem. Do as I say, and we’ll fix it before she wakes up.”

Zhang Yu’s fingertips once again overlapped with Bai Zhenzhen’s, gently pressing on several spots on Le Mulan’s lower abdomen.

Bai Zhenzhen continued, “Didn’t you say you have ice mana now? Infuse it to help freeze her wounds.”

As the ice mana was infused, Le Mulan’s eyelids fluttered and slowly opened. She immediately felt waves of coldness inside her body.

“What… what happened to me?” Le Mulan frowned slightly.

She only remembered messaging her brother when suddenly there was a loud bang, and then everything went black, and she lost consciousness.

In her dazed state, Le Mulan saw Zhang Yu’s hand on her stomach. Feeling the continuous flow of mana from him, she subconsciously began to receive it, just as she did with mana infusions every day in the past.

“Is it time for mana infusion?”

The coldness in her internal organs made her shiver, and she instinctively reached out and hugged Zhang Yu in front of her.

Watching Le Mulan wake up and hug Zhang Yu tightly due to the cold, Bai Zhenzhen circled the two, filming and nodding in satisfaction. “Excellent, excellent. It seems her body is fine, Yuzi. Now you don’t have to worry about paying compensation.”

But as Zhang Yu felt Le Mulan wriggling in his arms, her cold, smooth limbs brushing against him, he couldn’t help but give her a gentle shake and said, “Stop squirming.”

Le Mulan’s brain, still muddled from the impact, mumbled as she rubbed against Zhang Yu, “Not warm enough.”

Bai Zhenzhen said, “Didn’t you hear her say she’s not warm enough? Hurry up and heat her up, don’t let Le Mulan get frostbite.”

Helpless, Zhang Yu could only activate his muscles to raise his body temperature and warm Le Mulan.

But feeling Le Mulan still squirming in his arms, and his sweat gradually mingling with her, Zhang Yu found himself constantly distracted.

Especially with his mind divided into four, the four layers of thought in his mind brought four layers of distractions. It was like pressing down a gourd only to have a dipper float up, causing various distracting thoughts to fly like snowflakes, making it impossible to calm his mind.

Bai Zhenzhen reminded him from the side, “Why has your posture for pressing the wound changed?”

“Zhang Yu, when I was fighting with you just now, I noticed that your current thinking is very active, and your moves are unconstrained and imaginative, but they don’t form a cohesive whole. There’s always a lack of unified coordination.”

“I don’t know what caused this situation for you, but you must remember that no matter how your thoughts jump, they must be carried out with a single will. Otherwise, the more thoughts you have, the more they will act like scattered troops, which is harmful rather than beneficial to yourself…”

Listening to Bai Zhenzhen’s instruction, a sudden flash of insight struck Zhang Yu’s mind.

“Carried out with a single will.”

Scenes from his recent fight with Bai Zhenzhen appeared before his eyes.

“That’s right, with a mind divided into four, there must be a primary and secondary, otherwise, they will contradict each other.”

In Zhang Yu’s mind, ever since his Immeasurable Heart Inner Dharma Body leveled up to 20, the originally roaring two-headed white ox had transformed into a four-headed white ox.

At that moment, with a thought from Zhang Yu, one of the heads suddenly expanded and grew larger, seemingly becoming the main brain, while the other three ox heads contracted and guarded around the main head.

With a roar, the main head bellowed, “You! Control the hands and squeeze the wound!”

“You! Manage the mana flow and maintain the mana infusion!”

“You! Activate the muscles and heat the body.”

“Me? I will suppress distracting thoughts.”

The changes in the mental cultivation technique seemed numerous, but the series of transformations in his mind happened in an instant relative to the outside world.

In that single moment, Zhang Yu’s ability to use his mind in four ways underwent a qualitative change. Instead of four layers of thought working in unison, one layer acted as a central dispatcher, while the other three layers each carried out their assigned tasks.

A moment later, although Zhang Yu still felt a few distracting thoughts emerging in his mind, the large hand pressed on Le Mulan remained exceptionally steady, and the mana circulation and body heating were no longer affected in the slightest.

Le Mulan, feeling Zhang Yu’s steaming body, like a furnace, gradually quieted down.

A realization dawned on Zhang Yu: “This is truly the correct way to use multiple thoughts. There needs to be a primary and secondary distinction between thoughts, otherwise, they will interfere with each other and become a hindrance.”

Zhang Yu exclaimed, “Ah Zhen, thank you so much. You helped me break through a barrier.”

Bai Zhenzhen smiled slightly and waved her hand, saying, “Guiding my own son, that’s only natural, isn’t it?”

“Also, remember the damage assessment procedure I taught you today.”

“I’ll send you the recorded video later. Study it well so you can refer to it if you ever hit someone again.”

“It’s about time. I’ll be going now.”

Listening to Bai Zhenzhen’s words and watching her figure dissipate, Zhang Yu imagined the content of today’s recording in his mind and cursed inwardly, “These Kunxu people really are… What do you treat people as? You’ve completely dehumanized them.”

“So hot.” Le Mulan felt a scorching heat emanating from Zhang Yu’s body, and the warmth completely roused her.

Seeing that Le Mulan was fine, Zhang Yu said, “Are you alright now? If you are, you can get up.”

Le Mulan stood up, puzzled. “What happened to me just now?”

Zhang Yu’s face flushed, and he said, “I accidentally knocked you unconscious.”

“But I checked you, and your body is perfectly healthy, no issues.”

Le Mulan’s gaze shifted. She glanced at her sweaty body and noticed her outer clothes and pants were on the floor nearby.

At the same time, she checked the condition of her internal organs and understood that Zhang Yu had treated her with ice mana.

She sighed inwardly, “Zhang Yu checked my body and emergency-treated my wounds. Logically, I should thank him.”

“But he was also the one who hit me…”

Le Mulan pouted helplessly, “Don’t make such big movements in the dorm anymore.”

Zhang Yu nodded and casually agreed, but he thought to himself, “Now that I’ve comprehended the true usage of multiple thoughts, one thought will always maintain overall control in the future, and I won’t make mistakes so easily.”

The next day after school.

Zhang Yu arrived early at a training room in the Civil Engineering Department, as arranged with Director Gao.

Great Nascent Soul cultivator, True Lord Qingmu, has entered within 10 meters of you. Please remain quiet and do not project advertisements randomly.

Soon after, with the emergence of a Nascent Soul domain, Director Gao, clad in a Daoist robe, appeared before Zhang Yu.

Without any formalities or small talk, Director Gao wasted no time and immediately began teaching Zhang Yu directly.

“What I will impart to you today is the first of my Seven Civil Engineering Arts, the Xuanhuang Mountain Suppressing Seal.”

“This seal is both the foundation of the Seven Arts and immensely beneficial for many large-scale construction methods in our Civil Engineering Department.”

Director Gao extended a finger, and a cluster of black-gold mana suddenly appeared at its tip.

“This is the Xuanhuang Qi that needs to be refined when cultivating the Xuanhuang Mountain Suppressing Seal.”

“This Qi simulates earthly gravity. When it attaches to an object, it can change its weight, making metal as light as a feather and cotton as heavy as a thousand jun.”

Hearing this, Zhang Yu’s heart stirred. He recalled Mo Shangjin’s Divine Mountain-Moving Power of Heavenly Kunlun, which directly controlled earthly gravity, allowing him to grasp everyone and everything on an entire flying boat from a distance in a single move and bring them down to the ground.

“Although this Xuanhuang Mountain Suppressing Seal cannot control earthly gravity, its ability to simulate and regulate weight proves it worthy as the foundation of the Seven Civil Engineering Arts.”

As Director Gao continued his explanation, Zhang Yu further understood the differences between the Xuanhuang Mountain Suppressing Seal and the Divine Mountain-Moving Power of Heavenly Kunlun.

The Divine Mountain-Moving Power of Heavenly Kunlun could be applied to people and objects from a distance, allowing substances to be freely dragged and torn.

In contrast, the Xuanhuang Mountain Suppressing Seal required the attachment of Xuanhuang Qi before it could adjust weight.

Furthermore, if a human body resisted with mana after Xuanhuang Qi was attached, the Xuanhuang Qi could be dispelled, making it difficult for the effect to take hold.

Although it was much weaker than the Divine Mountain-Moving Power of Heavenly Kunlun, it was still the foundation of the Seven Civil Engineering Arts, so Zhang Yu studied it very diligently.

Especially the ability to adjust weight, which was clearly very useful for construction on sites and could further increase his work efficiency and salary level, naturally made Zhang Yu even more dedicated to learning it.

Director Gao patiently guided Zhang Yu through the circulation path of the Xuanhuang Mountain Suppressing Seal once, then said, “If the Xuanhuang Mountain Suppressing Seal is the foundation of the Seven Civil Engineering Arts, then this Xuanhuang Qi is the foundation of the Xuanhuang Mountain Suppressing Seal.”

“However, this Xuanhuang Qi can only be refined by influencing the balance of Yin and Yang and the changes of the Five Elements within the body, which truly emphasizes a slow, painstaking effort.”

“Ordinary students can’t hope to grasp it in less than a few weeks. Even the top student in each class often takes several days to get started…”

A few minutes later, after completing the first circulation path of the Xuanhuang Mountain Suppressing Seal with numerous errors, Zhang Yu knew he had already learned the cultivation method.

But of course, he wouldn’t boast that he had already mastered it.

“If I said it directly, who knows how Director Gao would look at me.”

“Besides, it’s a rare chance to spend more time with a leader, so why not?”

So, Zhang Yu proceeded to make slow, gradual progress, following the cultivation insights that emerged in his mind.

Anyway, for him, as long as he performed it once, there would be progress recorded in his Feather Book. Whether the execution process was clumsy or excellent made no difference.

One hour later.

Zhang Yu asked, “Master, this Xuanhuang Mountain Suppressing Seal is indeed difficult to grasp. I wonder how long it took the fastest practitioners throughout history to master it?”

Director Gao said calmly, “I told you this cultivation method is profound and difficult to learn and master. It’s perfectly normal for you to practice it for several days.”

“As for those who grasp it quickly, the fastest took about half an hour.”

“Even I took about an hour to learn this method back then.”

Fifteen minutes later, Zhang Yu condensed his first wisp of Xuanhuang Qi.

In total, it took 1 hour and 15 minutes for him to officially grasp the Xuanhuang Mountain Suppressing Seal.

Looking at the wisp of black-gold mana at Zhang Yu’s fingertip, Director Gao knew that his boasted “one hour” was a slight exaggeration, whereas Zhang Yu’s 1 hour and 15 minutes was the genuine article.

He thought to himself, “The time I spent… it was probably closer to two hours, wasn’t it?”

“This kid…”

Meeting Zhang Yu’s gaze, Director Gao slowly nodded and said, “Not bad. The Xuanhuang Mountain Suppressing Seal emphasizes accumulation over time. Go back and cultivate diligently; you must not relax in the slightest.”

Watching Zhang Yu’s retreating back, Director Gao took a deep breath and sent a message to True Lord Magnetic Pole.

Director Gao: Guess how long it took my new disciple to grasp the Xuanhuang Mountain Suppressing Seal?
Director Gao: 1 hour and 15 minutes!
True Lord Magnetic Pole: Your disciple is amazing! [Smile]
