Bai Zhenzhen asked, “Your Wanfa University didn’t teach any battlefield first aid?”

Zhang Yu was surprised to hear that, then said enviously, “You guys still have first aid classes.”

Bai Zhenzhen said, “Maybe it’s because all the major insurance companies currently refuse to insure our department.”

“Okay, let’s get started. Give me full-view permission, then follow my movements.”

Bai Zhenzhen’s figure flashed, projecting in front of Zhang Yu.

With the full-view permission activated, Bai Zhenzhen was now like a person present in the dormitory!

She squatted beside Le Mu Lan and said to Zhang Yu, “Stretch out your hand and follow my movements…”

Zhang Yu’s hands overlapped with Bai Zhenzhen’s projected hands and gently stroked Le Mu Lan’s lower abdomen, beginning to examine her injury!

A moment later, Bai Zhenzhen nodded slightly and said, “The situation is alright, not a big problem, just a slight injury to the internal organs!”

“For this kind of minor problem, just do as I say, and we can fix it before she wakes up!”

Zhang Yu’s fingertips overlapped with Bai Zhenzhen’s again, lightly pressing on several spots on Le Mu Lan’s lower abdomen!

Bai Zhenzhen continued to guide, “Didn’t you say you have a reserve of cold ice magic power now? Inject it inside to help her freeze the wound!”

With the input of cold ice magic power, Le Mu Lan’s eyelids trembled slightly and slowly opened, feeling waves of cold surging inside her body!

“I… What happened to me?” Le Mu Lan frowned slightly!

She only remembered sending a message to her brother, then suddenly a loud noise, followed by everything going black and losing consciousness!

At this moment, in a daze, Le Mu Lan looked at Zhang Yu’s hand on her abdomen, feeling the constant magic power being transmitted. She unconsciously started to accept it, just like the usual daily magic power infusion!

“Starting to infuse magic power?”

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

Seeing Le Mu Lan wake up and hug Zhang Yu tightly due to the cold, Bai Zhenzhen circled around the two of them, taking photos and nodding in satisfaction, “Not bad, not bad. Looks like there’s no major physical issue. Yu Zi, you don’t need to worry about paying compensation now!”

But Zhang Yu felt Le Mu Lan constantly twisting in his arms, and felt her icy limbs sliding across his body. He couldn’t help but shake her, saying, “Stop twisting!”

Le Mu Lan’s brain was still a bit confused from the impact. She rubbed against Zhang Yu and mumbled, “Not warm enough!”

Bai Zhenzhen said, “Didn’t you hear her say not warm enough? Hurry up and add some heat, don’t let Le Mu Lan freeze and get injured!”

Zhang Yu was helpless and could only move his muscles to raise his body temperature to warm Le Mu Lan!

But feeling Le Mu Lan still twisting in his arms, and feeling his sweat gradually sticking to him, Zhang Yu found himself constantly getting distracted!

Especially under the condition of one heart and four uses, the four layers of thinking in his brain generated four layers of distracting thoughts. It was like pushing down a gourd only for the dipper to float up again, causing various distracting thoughts to fly around like snowflakes, making it impossible to calm down!

Bai Zhenzhen reminded him from the side, “How did your posture for pressing the wound change?”

“Zhang Yu, when I fought against you just now, I just discovered that your thinking is very active now, your moves are unrestrained and not rigid, but they lack continuity and are always not uniformly directed!”

“I’m not sure what caused this situation, but you must remember, no matter how jumping your thinking is, it all needs to be penetrated by the same will, otherwise, the more thoughts you have, the more like scattered soldiers they will be, which is harmful to yourself and not beneficial…”

Listening to Bai Zhenzhen’s teaching, a ray of bright light seemed to suddenly flash in Zhang Yu’s heart!

“Penetrated by the same will!”

The scene of fighting with Bai Zhenzhen just now floated in his eyes one by one!

“That’s right, one heart and four uses must have a primary and secondary distinction, otherwise, they will contradict each other!”

In Zhang Yu’s brain, since the Wuliang Heart Inner Dharma Body was upgraded to level 20 last time, the original roaring two-headed white ox had already become a four-headed white ox!

At this time, with Zhang Yu’s thought, one of the heads suddenly swelled larger, as if becoming the main brain, while the other three ox heads all shrunk, surrounding the main head!

Accompanied by a roar, the main head roared, “You, responsible for controlling the palm and squeezing the wound.”

“You, responsible for operating the magic power and maintaining the magic power infusion.”

“You, responsible for moving muscles and heating the body!”

“I, I will suppress the distracting thoughts!”

The changes in the operation of the heart method seemed numerous, but the series of changes in the brain were only an instant relative to the outside!

In this instant, Zhang Yu’s one heart and four uses underwent a qualitative change. It was no longer four layers of thinking collaborating equally, but one layer of thinking directing uniformly, with the other three layers of thinking each performing assigned tasks!

A moment later, although Zhang Yu still felt some distracting thoughts appearing in his heart, the big hand pressing on Le Mu Lan’s body was abnormally stable, and the other magic power operations and body heat were no longer the slightest bit interfered with!

Le Mu Lan felt the steaming heat from Zhang Yu, his body like a furnace, and gradually quieted down!

A bit of understanding surged in Zhang Yu’s heart, “This is the correct way to use multi-layered thinking. There also needs to be a primary and secondary distinction between thoughts, otherwise, they will interfere with each other and instead drag you down!”

Zhang Yu sighed, “A Zhen, thank you very much, you helped me break through an obstacle!”

Bai Zhenzhen smiled slightly and waved her hand, “It’s my own son, this is nothing!”

“Also, you must remember the damage assessment process I taught you today!”

“I will send you the recorded video later, you must study it carefully. If you hit someone later, you can also take it out as a reference!”

“It’s getting late, I’ll leave first!”

Listening to Bai Zhenzhen’s words and watching her dissipating figure, Zhang Yu imagined the content recorded today and secretly cursed in his heart, “These Kun Xu people are really… they treat people as if they’re completely alienating them!”

“So hot!” Le Mu Lan felt a wave of scorching heat coming from Zhang Yu’s body and was completely awakened by the heat! Seeing that Le Mu Lan was fine, Zhang Yu said, “Are you okay? If you’re okay, get up!”

Le Mu Lan stood up and asked doubtfully, “What happened to me just now?”

Zhang Yu’s face turned slightly red and he said, “I hit you and you fainted!”

“But I’ve already checked you over, your body is very healthy, no big problems!”

Le Mu Lan’s gaze moved slightly and she looked at her sweat-drenched body, discovering that her outer clothes and pants were all placed on the floor beside her!

At the same time, she felt the situation of her internal organs and realized that Zhang Yu had used cold ice magic power to treat her!

She felt helpless in her heart, “Zhang Yu helped me check my body and even handled the wound in an emergency. According to reason, I should thank him!”

“But he was the one who hit me…” Le Mu Lan pouted helplessly, “Don’t do such big movements in the dormitory later!”

Zhang Yu nodded casually in agreement, but his heart was thinking, “Now I’ve comprehended the true way to use multi-layered thinking. Later, there will always be one thought in overall control, so I definitely won’t make mistakes easily again!”

The next day after school!

According to the agreement with Director Gao, Zhang Yu arrived at a practice room in the Earth Wood Department in advance!

Yuan Ying expert Qing Mu Zhen Jun has entered within 10 meters of you, please keep quiet and do not casually project ads!

Not long after, accompanied by the appearance of the Yuan Ying domain, Director Gao, wearing a dao robe, was already standing in front of Zhang Yu!

Without any pleasantries or small talk, Director Gao seized the time as soon as he arrived and got straight to the point, teaching Zhang Yu!

“What I want to impart to you today is the first absolute of my Earth Wood Seven Absolutes, Xuan Huang Zhen Yue Seal!”

“This seal is both the foundation of the Seven Absolutes and is extremely helpful for the numerous large construction methods of my Earth Wood Department!”

Director Gao extended a finger, and a cluster of black and gold magic power immediately appeared at his fingertip!

“This is the Xuan Huang Qi that needs to be condensed to cultivate the Xuan Huang Zhen Yue Seal!”

“This qi simulates the gravity of earth evil. After attaching to an object, it can change the weight of the object, making metal light as a feather and cotton heavy as a thousand jun!”

Zhang Yu’s heart moved after hearing this, and he thought of the Tian Kun Lun Move Mountain Divine Power displayed by Mo Shan Jin. At that time, he directly controlled the gravity of earth evil. In one move, he just grabbed all the people and things on the entire flying boat and pulled them towards the earth!

“Although this Xuan Huang Zhen Yue Seal cannot control the gravity of earth evil, after simulating it, it can adjust the weight. It indeed lives up to its name as the foundation of the Earth Wood Seven Absolutes!”

In Director Gao’s subsequent explanation, Zhang Yu understood more clearly the difference between Xuan Huang Zhen Yue Seal and Tian Kun Lun Move Mountain Divine Power!

Tian Kun Lun Move Mountain Divine Power can directly act on people and objects and can arbitrarily drag and tear substances!

While Xuan Huang Zhen Yue Seal needs to first use Xuan Huang Qi to attach before it can adjust the weight!

Moreover, after Xuan Huang Qi attaches, if the human body resists with magic power, the Xuan Huang Qi will be expelled, making it difficult to have an effect!

Despite being much weaker than Tian Kun Lun Move Mountain Divine Power, it is after all the foundation of the Earth Wood Seven Absolutes, and Zhang Yu learned it very seriously!

Especially the ability to adjust the weight, which is obviously very useful for construction on the work site and can further improve his work efficiency and increase his salary level, Zhang Yu naturally learned it more attentively!

Director Gao patiently guided Zhang Yu through the merit route of Xuan Huang Zhen Yue Seal once, then said, “If Xuan Huang Zhen Yue Seal is the foundation of the Earth Wood Seven Absolutes, then Xuan Huang Qi is the foundation of Xuan Huang Zhen Yue Seal!”

“But this Xuan Huang Qi needs to mobilize the yin and yang balance of the body’s flesh and blood and the changes of the five elements to condense a thread. It most emphasizes a long and painstaking effort!”

“Ordinary students will have difficulty entering the door in less than a few weeks. Even the class first of each session often needs to spend several days to enter the door…”

A few minutes later, Zhang Yu completed the merit route of Xuan Huang Zhen Yue Seal for the first time. Although there were many errors and omissions, he knew that he had already learned this method!

Of course, he would not rashly say that he had already successfully practiced it!

“If I say it directly, who knows how Director Gao will look at me!”

“Besides, it’s rare to have the opportunity to interact with the leader for a while longer, what’s not good about that?”

Thus, next, Zhang Yu followed the cultivation experience that appeared in his brain, making slow progress bit by bit!

Anyway, for him, as long as operating it once could make progress on the Feather Book, it didn’t make much difference whether the operation process was clumsy or excellent!

An hour later!

Zhang Yu asked, “Master, this Xuan Huang Zhen Yue Seal is indeed very difficult to enter the door! I wonder how long it took the fastest person in the past to practice successfully.”

Director Gao said faintly, “I told you this method is profound and difficult to learn and refine. It’s very normal for you to cultivate for a few days!”

“As for entering the door quickly, the fastest is probably half an hour.”

“Even when I learned this method, it took about an hour!”

After another 15 minutes, Zhang Yu finally condensed the first thread of Xuan Huang Qi!

The total time used was 1 hour and 15 minutes, and Xuan Huang Zhen Yue Seal officially entered the door!

Looking at the wisp of black and gold magic power at Zhang Yu’s fingertip, Director Gao knew that the 1 hour he had mentioned was a bit exaggerated, while Zhang Yu’s 1 hour and 15 minutes in front of his eyes was undoubtedly real! He thought to himself, “The time I spent back then… was approximately two hours.”

“This kid…”

Facing the gaze Zhang Yu cast, Director Gao slowly nodded and said, “It’s not bad. Xuan Huang Zhen Yue Seal emphasizes accumulating over time. You must cultivate well after you go back, and absolutely not be the slightest bit slack!”

Looking at Zhang Yu’s departing back, Director Gao took a deep breath and sent a message to Ci Ji Zhen Jun!

Director Gao: Guess how long it took my new disciple to enter the door of Xuan Huang Zhen Yue Seal?

Director Gao: 1 hour and 15 minutes.

Ci Ji Zhen Jun: Your disciple is really great. Smile.
