Chapter 45 The Wonderful Use of Techniques, The Azure Scale Dilemma

"I choose the Jade Slip for Inheritance."

With a slight thought, a fiery red jade slip appeared in Lu Yu's hand in an instant.

As his soul power slowly swept across the jade slip, information about the three cultivation techniques immediately appeared in his mind.

The Heavenly Fire Forging Technique uses a different kind of fire to temper the soul. Each forging process removes impurities from the soul and improves its quality, eventually transforming it into a ball of soul fire. As long as the flame is extinguished, the soul will never perish.

It is divided into two major realms: Soul Forging and Fire Transformation.

Soul Forging corresponds to cultivation in the mortal realm.

Transforming into fire corresponds to cultivation in the spiritual realm.

However, the step of transforming the soul into fire is extremely dangerous; the slightest mistake will result in spontaneous combustion and ashes. According to the cultivation method, a fifth-grade spiritual pill called the Bright Soul Pill is required as an aid.

If converted to the rank of pills in the Dou Qi Continent, it would be an eighth-grade pill.

As for the Heaven-Burning Spirit-Igniting Technique, it is a secret method that temporarily enhances one's strength by burning a strange fire within the body. The extent of the enhancement depends on the intensity of the strange fire and the compatibility between the strange fire and the individual.

The stronger the strange fire, the higher its compatibility with the person, and the greater the improvement.

However, after use, the internal fire will weaken for a short time and needs to be nurtured for a period of time before it can be used again, but it will not cause any harm to the person.

It can be said that the price of using this secret technique was almost entirely borne by the strange fire within the body.

The final technique, the Ancestral Flame Scripture, requires the bloodline of the Fire Spirit Clan to cultivate. For Lu Yu, this technique can only be used as a reference and has little practical use.

The reason for exchanging for this cultivation technique in the simulation was simply to avoid arousing suspicion among the remnant souls of the Heavenly Sovereigns of the Fire Spirit Clan.

"The Heavenly Fire Soul Forging Technique and the Heaven Burning Spirit Technique are both considered high-level Earth-rank cultivation techniques and secret arts, but even at the high-level Earth-rank level, they are considered top-quality items."

"Those old guys from the Fire Spirit Clan really do have some good stuff..."

Lu Yu exclaimed in admiration, then glanced at the jade slip again, shook his head, and said, "The cultivation difficulty is also high. It will probably take several months to even get started..."

He pondered for a moment, then made up his mind: "I should cultivate the Heaven-Burning Spirit-Igniting Technique first, since secret techniques are always easier to cultivate than soul cultivation techniques..."

Having made up his mind, Lu Yu immediately sat cross-legged, facing upwards, and began to meditate.

……

Several days later, on the back mountain of the Xiao family.

"Whoosh-"

Lu Yu's figure flickered like a ghost, leaving several crimson afterimages beneath his feet. With a slight tremor of his fingertips, dozens of hair-thin threads of fire suddenly shot out, weaving into a net of fire in the air, enveloping the white-clad girl opposite him.

"So fast!"

The Little Fairy Doctor's pupils contracted slightly. Her slender feet lightly touched the ground, and she retreated rapidly. With a flick of her wrists, colorful butterflies swirling with purple poisonous mist fluttered out from her sleeves, heading towards the oncoming net of fire.

"Boom! Boom! Boom!"

The poisonous butterfly collided with the fire line, instantly exploding into clouds of purple mist. However, the crimson fire line continued its relentless advance, piercing through the poisonous mist and attacking again.

In this moment of lightning and fire -

"boom!"

Lu Yu's afterimages suddenly exploded beneath his feet, and his figure accelerated abruptly. In the blink of an eye, he broke through the poisonous fog blockade, closing in on Little Fairy Doctor, his right palm carrying a scorching wave of energy, aiming straight for her center!
"Congeal!"

Despite the danger, Little Fairy Doctor remained calm and quickly formed hand seals, condensing layers of purple poison in front of her in an attempt to block the thunderous attack.

But Lu Yu's lips curled up slightly, and his afterimage exploded beneath his feet as he soared into the sky. He did a somersault in mid-air and then transformed into a crimson meteor, swooping down with a sharp palm wind!

"This..." Little Fairy Doctor looked up at the figure descending from the sky, and stood there stunned for a moment.

Just as the palm strike was about to hit her, Lu Yu's Purple Cloud Wings suddenly unfolded on his back, and he gracefully spun past her, landing lightly on the ground.

"You lost again."

Lu Yu turned around and smiled, "The dishes and chopsticks are yours tonight."

"unfair!"

The Fairy Doctor stomped her foot in anger, saying, "You have both a low-level movement technique and a flying combat skill. Your movement technique is unpredictable. I can't even touch the hem of your clothes! It's not fair even if we're at the same level!"

Lu Yu shook his head and interrupted, "You are now a five-star Grand Dou Master, but you lack practical experience despite your high level of cultivation. If you are not convinced, I will not use movement techniques or flight skills to compete with you again this time?"

"Great!" Little Fairy Doctor's eyes lit up.

Soon after……

"It doesn't count this time!"

"You are cheating!"

"My hand slipped..."

An hour later, Little Fairy Doctor slumped to the ground, dejected, and said, "We're clearly at the same cultivation level, so why is there such a big difference?"

"If you were being relentlessly pursued by a veteran Dou Huang for months, using all sorts of tricks, would you still be this strong..."

Lu Yu thought this to himself, but smiled without saying a word.

His fighting skills were honed through the torture he endured at Hai Bodong's hands; they were refined through countless trials, making him stand out even among his peers.

"Alright, starting today, you will train with me during the day. In the art of combat, practice makes perfect. If you only bury yourself in hard work, you will suffer a great loss sooner or later."

Lu Yu patted the dust off his robes and said with a serious expression.

Upon hearing this, Little Fairy Doctor blinked and asked, "What about Qing Lin? Doesn't she need to cultivate together?"

"She's still just a fighter."

Looking at Qinglin cultivating in the distance, Lu Yu sighed softly, "The most important thing now is to solidify our foundation. It's not too late to hone our combat skills after we break through to the Dou Shi realm."

A thoughtful look flashed in his eyes: "Besides, her cultivation path is different from ours..."

As the Azure Serpent Three-Flower Pupil is a soul-type talent, in his view, nurturing Qing Lin must begin with soul power. Originally, he intended to pass on the Heavenly Fire Forging God Technique to Qing Lin, but after thinking about it, he felt it was quite inappropriate, as the prerequisite for cultivating this soul technique was having a different kind of fire.

Qinglin possesses the bloodline of the snake-people and has a cold, yin constitution, making him inherently incompatible with things like strange fire...

Even the method of creating a unique fire vein would probably be difficult to apply to her...

Therefore, he was quite troubled about how to cultivate Qinglin.

Lu Yu stroked his chin thoughtfully, his eyes gleaming with contemplation, thinking to himself, "Perhaps... I shouldn't limit my focus to the development of pupil techniques."

He looked up into the distance, as if he could see that vast and boundless world: "In that wider realm, the areas that those with strong soul power can explore are incredibly diverse. Far beyond the Dou Qi Continent, where only alchemy is a viable path..."

"Alchemy, weapon crafting, spirit arrays, insect control... each has its own strengths, making it a diverse and flourishing field."

Lu Yu pondered silently: "If I could find a secondary profession that could bring out the unique characteristics of the Azure Serpent's Three-Flower Pupil..."

Thinking of this, a smile crept onto his face. With the simulator's capabilities, acquiring a basic inheritance wasn't difficult. The real key lay in—

"What path can maximize Qinglin's potential?"
