Heaven rewards diligence, but there are always fairies plotting against me.

"Young friend Chu, I... no, I am Zhang Jianzhi, the elder of this library." Zhang Jianzhi clasped his hands in greeting.

"So it was Grand Secretary Zhang."

Chu Chang quickly hugged the jade slip to his chest and blinked in confusion.

He began to wonder: This old man was just lecturing him like "young man, you're too young," but how come he changed his way of addressing him in the blink of an eye?

"Young friend Chu"? "This humble one"?

This change in attitude is too fast! Could it be that my toxic chicken soup just now hit this old man's delusional soul right?

Although he was inwardly puzzled, Chu Chang maintained a flattered and honest demeanor on his face.

After all, the Grand Elder of the Library Pavilion—just hearing that name makes him seem like an unfathomable, low-level figure in the sect, definitely a powerful figure.

Seeing that Chu Chang's expression was normal, without any arrogance or flattery, Zhang Jianzhi's evaluation of him immediately rose several notches.

This young man is wise beyond his years, with a transcendent mind; he is truly an extraordinary person!

The thought that his life-or-death bottleneck, which had plagued him for decades, was showing signs of breaking down because of the boy's words made Zhang Jianzhi feel that this was a great cause and effect.

In the cultivation world, karma is of utmost importance. This is almost a debt of gratitude for "imparting knowledge and enlightenment," which he must repay.

"Young friend Chu," Zhang Jianzhi said earnestly, enunciating each word clearly, "If you encounter any problems you can't solve within the sect, or if you lack guidance in your cultivation, feel free to come to the library to find me. As long as it's within my power, I, Zhang Jianzhi, will never refuse."

Upon hearing this, Chu Chang was immediately delighted.

Wow, I just chatted around for a bit and ended up getting a bodyguard and a VIP green card?

"Oh dear... then this disciple will thank you in advance, Elder Zhang!" Chu Chang hurriedly said.

Afterwards, Zhang Jianzhi couldn't suppress the urge to go into seclusion and meditate, but he was also reluctant to let Chu Chang leave so soon, so he pulled him aside and forced him to chat for a few more minutes.

But Chu Changsheng was afraid that if he continued the conversation, he would give himself away, so he started to use Taoist esoteric jargon like "let nature take its course" and "governing by doing nothing" that he had heard too many times in his previous life to fool him.

However, these words, spoken by Zhang Jianzhi who was eager to make a breakthrough, became profound secrets, leaving him scratching his head and exclaiming how wonderful they were.

"Grand Secretary Zhang, then this disciple will go back and study the 'Invincible Vajra Technique' first, so as not to disturb your peaceful cultivation." Chu Chang seized the opportunity and took his leave.

"Alright, alright! Take care, young friend. If you have any questions, feel free to ask me!" Zhang Jianzhi personally escorted Chu Chang to the entrance of the library. His attentive manner would have made the outer disciples' eyes pop out if they saw him.

Chu Chang walked out of the library with the jade slip containing the cultivation technique in his arms. Facing the mountain breeze, he thought to himself with satisfaction: It's done. Next, I need to find a secluded place to see what kind of tricks I can pull off with my extremely yang physique and the "Invincible Vajra Technique".

…………

…………

Back at his residence, Chu Chang couldn't wait to sit cross-legged and stick the jade slip of the "Invincible Vajra Skill" to his forehead.

As a cool, warm energy flowed into his mind, the system panel lit up slightly, and a new line of text quickly appeared: [Technique: Vajra Invincible Skill (Beginner 0/500)]

It takes quite a bit of experience to get started.

However, the more experience points one has, the more extraordinary this technique is.

Chu Chang grinned, took a deep breath, and began to try circulating his internal energy according to the method in the jade slip.

According to the original description, this technique requires practitioners to endure the pain of skin and flesh being peeled away in a boiling medicinal bath, gradually tempering their physical body.

However, the situation changed completely the moment the blood and qi of Chu Chang's "extreme yang constitution" were activated by the cultivation method.

boom!

The intense yang energy within him was like an awakened volcano, its scorching heat instantly engulfing his limbs and bones.

That violent masculine energy surged through the meridians, perfectly matching the ultimate masculine essence of the "Invincible Vajra Skill".

The skin and flesh defenses that ordinary people need to soak in medicinal liquid for years to expand are instantly broken through like a hot knife cutting through butter under the frenzied flushing of the extremely yang blood and qi.

Countless streams of intense energy flowed into his skin and flesh, and a faint golden glow even appeared on Chu Chang's body, making his muscle texture even tighter and more refined.

As night fell, the moon and stars were few and far between.

A crisp system notification sounded in Chu Chang's ears. He opened his eyes and pulled up the panel.

[Invincible Vajra Skill: Minor Success (0/1000)]

"Holy crap, it's already partially completed in half a day?!"

Chu Chang was stunned.

What happened to the saying that skeletal structure is fixed and unsuitable for cultivation? What happened to the saying that it's extremely difficult to get started?

He originally thought that with his daily practice, he should be able to achieve some success in a month or two.

Who would have thought that it would only take half a day!

Is this the advantage brought by physical constitution?

To test the effect, Chu Chang gritted his teeth and picked up an ordinary iron sword from the side.

He took a deep breath and slashed down hard at his left arm!

"when!"

A dull metallic clang rang out.

There was no bloody scene. Chu Chang looked down and saw that there was only a faint white mark on his arm, without even breaking the skin. The steel knife was even shaken slightly by the impact.

"No problem! Haha, this defense is amazing!"

Chu Chang rubbed his arm and couldn't help but laugh out loud: "I know! My extremely yang constitution is already extremely strong and yang, so cultivating this equally powerful body-strengthening technique is like dry wood meeting a raging fire—a perfect match!"

However, after mastering the "Invincible Vajra Skill," the side effects of the extremely yang constitution also began to appear.

At this moment, his whole body was burning hot, his skin was red, and he was like a boiling steamer, even his breath carried scorching heat.

"It's unbearably hot, we need to cool things down."

Chu Chang's mouth was dry, so he quickly took off his sweat-soaked clothes, leaving him in only a pair of shorts. He grabbed a wooden bucket and rushed to the yard, drew a bucket of ice-cold well water, and poured it over his head with a "splash".

The cool well water splashed onto his burning skin, instantly turning into plumes of white steam that rose up, making him breathe a long sigh of relief.

Just then, the courtyard gate made a soft sound, and Gu Ling Shuang walked in carrying an exquisite bamboo woven vegetable basket.

"Hey, Ah Chang, are you taking a bath?"

As Gu Ling Shuang spoke, she subconsciously glanced at Chu Chang, but upon seeing him, her eyes widened instantly, and she froze on the spot.

Because she was horrified to discover that things were different; the Chu Chang in front of her was completely different!

Although Chu Chang was quite skilled, he was rather thin.

But at this moment, with his clothes off, his shoulders were as broad as mountains, his chest muscles were full, and the muscle lines of his abdomen were as if carved by a knife and axe. Under the refraction of moonlight and water vapor, he exuded a masculine beauty that made people blush.

Especially the explosive power that seemed to flow beneath his skin, so intense that even the air seemed to be slightly distorted by the heat emanating from his body.

Stared at so intently by Gu Ling Shuang, Chu Chang's expression turned strange: "Miss, what brings you here?"

A barely perceptible blush crossed Gu Ling Shuang's fair face. She looked away somewhat flusteredly, raised the vegetable basket in her hand, and said softly, "You were taking the exam in the Enforcement Hall today, and then went to the Library Pavilion this afternoon. You must be exhausted. I just cooked two dishes for you in the small kitchen and brought them over."

Chu Chang was stunned.

He looked at Gu Ling Shuang in disbelief, his heart filled with turmoil.

This is the eldest daughter of the Gu family, a pampered and proud young lady who is usually focused on cultivation. Now she is actually cooking for him, her little follower, and even delivering the food to his door.

This was something we wouldn't have dared to dream of in the past!

"What are you standing there for? Eat up, it'll get cold soon." Gu Ling Shuang couldn't help but urge him coquettishly when she saw his dazed look, but the corners of her mouth turned up slightly.

"Oh, okay! Thank you so much, Miss. You're so kind." Chu Chang felt warm inside and thanked her repeatedly.

He shook the water droplets off his head and was about to grab a rag to dry himself off so he could get dressed and eat.

Before he could even move, Gu Ling Shuang said first, "You're all wet, don't catch a cold. Let me dry you off."

After saying that, before Chu Chang could react, she naturally jogged into the kitchen and skillfully retrieved a clean, dry towel.

Holding a towel, Gu Ling Shuang walked back to the courtyard and stood behind Chu Chang, gently wiping the moisture off his back.

Warm fingertips pressed against Chu Chang's thick back through the towel, sending shivers of electric-like sensation through him.

Chu Chang lowered his head slightly, inhaling the faint fragrance around him and feeling the gentle pressure on his back. He couldn't help but mutter to himself, "Miss is being exceptionally gentle today!"
