Chapter 170 The Inheritance of the Thunder Palace, Farewell to Brother Yan

"Sigh, this is too tragic. It seems I can't choose the identity of the evil spirit race anymore—"

Lu Yu sighed and then shook his head. If he had known beforehand that the simulation would turn out this way, he probably would have preferred to start with a more stable academy-style approach.

But it was this simulation that made him realize the pitfalls of this option.

It can only be said that nothing is absolute, and the significance of simulation lies precisely in this: to try and fail at the lowest cost and explore the possible consequences of different choices.

Immediately, his gaze swept over the three options before him:

A wisp of pure demonic energy. This stuff is considered extremely poisonous in the Dou Qi Continent. It might be useful for luring out extraterrestrial evil races in the Great Thousand Worlds, but it's practically useless in the Dou Qi Continent. If it were used, it would attract real extraterrestrial evil races, and the entire continent would suffer.

Supreme-grade Thunder Marrow Crystal is indeed a peerless treasure, but with his current Dou Zun realm cultivation and the strength of his strange fire, he is simply powerless to refine such a material comparable to a ninth-order Dou Sheng, making it a useless material.

Therefore, it seems that we can only choose the last option.

After careful consideration, Lu Yu made his choice, silently reciting in his heart: "I choose number three, the token of entry into the Ancient Thunder Palace."

As he finished speaking, a dark, ancient token, faintly shimmering with lightning, fell into his hand.

"This thing doesn't seem particularly special at all—"

Lu Yu curiously examined the token in his hand, his fingers tracing its surface. At first, it felt cold and hard, like some kind of strange iron ore, but upon closer inspection, he discovered that its texture was warm and delicate, even faintly possessing the luster of jade.

The contradictory sensation aroused his curiosity.

Immediately, he thought for a moment, and a ball of golden pagoda fire suddenly ignited in his hand. He carefully placed the token on the flame to burn it, trying to find out what it was.

However, even the terrifyingly high temperature of the Floating Pagoda Fire could not cause the charred token to change in the slightest.

On the contrary, the faint lightning on it seemed to be activated by the flames, suddenly becoming a little brighter and emitting a slight "crackling" sound, from which a trace of pure lightning power flowed out.

The instant that wisp of lightning power surged forth, Lu Yu felt a heat between his brows! A faint purple lightning bolt shot out from the token with lightning speed, directly piercing into his brow!

Nine Heavens Thunder-Summoning Technique!

Five large characters, imbued with the ancient and majestic will of thunder, were first and foremost deeply imprinted on the depths of his soul.

Immediately afterwards, a vast torrent of information surged in, revealing countless detailed and profound methods on how to sense and activate the power of thunder in the world, how to use the power of thunder to temper spiritual power, and how to use the power of thunder to temper the physical body, all unfolding clearly in his sea of ​​consciousness like a scroll.

A moment later, Lu Yu slowly opened his eyes, his gaze filled with undisguised surprise and understanding. When he looked again at the still charred and unremarkable token in his hand, his expression had completely changed, now filled with shock and reverence.

"It's just an introductory technique, yet it has reached the Supreme level. This Ancient Thunder Palace truly lives up to its reputation as a powerful force of the ancient times."

Lu Yu stroked the still-antique token in his hand, his heart still reeling from the shock.

Although this Nine Heavens Thunder-Drawing Technique is merely an introductory foundational method for the Ancient Thunder Palace, it is a complete system with a majestic and righteous atmosphere. It is a rare method for cultivating both physical body and spiritual power, and its exquisite and profound aspects far surpass many other cultivation techniques of the same level on the Dou Qi Continent.

Such a feat is far beyond the reach of ordinary forces in the world today.

"In comparison, although that ancient Heavenly Emperor was exceptionally talented, single-handedly establishing the ancient Heavenly Palace and shaking the vast world, his rise to power was ultimately too short, and his accumulated foundation was probably far inferior to that of a true ancient overlord, otherwise—"

Lu Yu paused slightly, a hint of regret and reverie flashing in his eyes. If the ancient Heavenly Palace had survived to this day, perhaps the situation would be completely different, and the格局 (geju, a concept encompassing the overall structure and overall situation) of the world would be entirely different.

But history has no "what ifs." The early death of the Heavenly Emperor led to the seclusion of the ancient Heavenly Palace, which paved the way for Mu Chen's rise to power.

"Forget it, there's no point in thinking about it too much. The method of tempering the body by using the power of lightning in the Nine Heavens Thunder-Drawing Technique is quite mysterious, and I may be able to learn a thing or two from it."

"Accelerate the cultivation progress of the Heaven-Burning Glazed Body."

Lu Yu composed himself, bringing his thoughts back to reality, and his gaze hardened once more.

As an eighth-grade alchemist, he has no shortage of pill lightning. This kind of violent energy that others avoid at all costs is an excellent resource for him to temper his physical body and cultivate lightning techniques!
"The next time I refine an eighth-grade pill, I can try to use lightning to temper my body."

Soon after,

Lu Yu slowly emerged from the quiet room. In the courtyard, he saw Venerable Tianhuo sitting opposite Hei Qing on either side of a stone table, engrossed in a game of chess.

Ziyan squatted on a stone bench to the side, her little hand supporting her cheek, looking at the black and white pieces on the chessboard, her big purple eyes filled with confusion.

She couldn't understand the moves at all; she just found the pieces shiny and fun. She would occasionally reach out her little hand to touch a piece, only to be stopped by Hei Qing's helpless look.

She pouted and muttered under her breath, "What's so fun about arranging these stones around? I might as well eat them!"

Seeing this, Lu Yu shook his head helplessly.

Suddenly, a strong energy fluctuation came from the direction of the quiet room where Little Fairy Doctor was in seclusion, causing the energy of heaven and earth in the courtyard to tremble slightly.

The spirit-gathering array surrounding the meditation room flickered rapidly, and streams of pure poisonous fighting energy pierced through the door like thin gauze, clearly indicating that the critical moment for a breakthrough had arrived.

The commotion drew the attention of several people in the courtyard, who all turned to look.

A moment later, the roaring sound subsided, and the stone gate slowly opened.

The first thing that catches the eye is a pristine white expanse, untouched by any dust. Then, the Little Fairy Doctor, dressed in white, gracefully steps out of the quiet room.

After this breakthrough, she appeared even more beautiful and refined than before, with delicate, jade-like skin that subtly radiated a warm, moonlit glow, as if she had been reborn from the inside out.

The faint melancholy that once lingered in her unique pale purple eyes has vanished, replaced by an ever-brighter radiance.

Seven Star Dou Zong!

After taking the Jade Spirit Pill, Little Fairy Doctor actually jumped three stars, suddenly rising from a four-star Dou Zong to a seven-star Dou Zong!

Her gaze swept across the courtyard and immediately landed on Lu Yu. A bright and charming smile unconsciously curved her lips, and her voice was soft yet filled with barely suppressed joy: "It's a success."

Lu Yu stepped forward, his eyes filled with undisguised praise and a smile: "Congratulations, Xian'er. Seven-Star Dou Zong, it seems that the Jade Spirit Pill is indeed extraordinary." His gaze lingered on her for a moment, and he could also perceive the subtle and delightful change in her temperament.

"Ah."

Little Fairy Doctor nodded gently, her eyes conveying a subtle warmth. "I must thank you for the pills. During this seclusion, I have gained much better control over the poison in my body."

She hesitated for a moment, her voice tinged with anticipation, and said softly, "I have some questions about cultivation that I'd like to discuss with you in detail. It's a bit inconvenient here, so why don't we go to your room to talk?"

Lu Yu was slightly taken aback, then smiled and said, "Of course."

After saying this, he nodded slightly to Venerable Tianhuo and the others, and then walked side by side with Little Fairy Doctor towards the bedroom.

The two entered the room and raised their hands to set up a barrier, completely isolating themselves from all outside sounds and sights.

The moment this private space was formed, Little Fairy Doctor's previous reserve and aloofness vanished instantly. She suddenly turned around and flew directly into Lu Yu's arms, tightly wrapping her jade arms around his neck and burying her burning cheeks in his shoulder.

Immediately afterwards, a trembling yet firm whisper, as if bursting forth with intense emotion after being suppressed for a long time, rang clearly in his ears:

"love me!"

Lu Yu's body stiffened abruptly, and he froze on the spot. He could clearly feel the slight trembling of the delicate body in his arms and the unusually high body temperature. This was the Little Fairy Doctor he had never seen before, so passionate and proactive.

"Okay." His deep voice sounded in her ear, filled with unprecedented tenderness.

Before he finished speaking, he had already expertly wrapped his arms around her soft waist and lowered his head to cover her two warm, soft lips with his own.

The curtains were quietly lowered, concealing the enchanting atmosphere of the room, leaving only the sounds of intertwined breaths and occasional whispers.

——————————————————————————————

The next day,

On the bed, the brocade quilt slipped down to her waist. As if sensing the movement of the person beside her waking up, Little Fairy Doctor's eyelashes trembled slightly, and she slowly opened her pale purple eyes. The initial daze was quickly replaced by the memories of last night, and a captivating blush instantly crept up her cheeks and the tips of her ears.

She subconsciously brought her legs together, trying to pull her eye-catching jade feet back under the covers, but Lu Yu caught her with a smile.

Their eyes met, and the air was filled with unspoken warmth and a touch of embarrassment afterward.

She couldn't resist Lu Yu's mischievous gaze. Her eyes flickered, she gave him a light reproach, and, seemingly both shy and annoyed, she looked away first, propping herself up on her arms as she tried to get up.

"There's still plenty of time, no rush."

Lu Yu's deep voice was slightly hoarse, and with a slight exertion of his arm, he pulled her back into his warm embrace.

He felt the unconscious shyness of the beauty in his arms and murmured lazily, "It's rare to get a rest, stay with me a little longer."

——————————————————————————————————————

A few days later,

Lu Yu sat alone on a stone bench in the courtyard, his brows slightly furrowed. He placed two jade slips, one red and one white, on the stone table, rubbed his temples with a slight headache, and muttered to himself:

"The Great Luo Heavenly Flame Sword, a low-level Heaven-rank combat skill, and the Dragon Soaring Technique, a quasi-Heaven-rank combat skill, are indeed not easy to comprehend."

Just then, a pair of slender hands gently landed on his tense shoulders, massaging them with a light touch. Little Fairy Doctor had appeared behind him unnoticed, her voice as gentle as water:
"Mastering Heavenly Rank combat techniques is not something that can be accomplished overnight, so why rush it? Let's have some tea and rest for a while."

Lu Yu shook his head, picked up his teacup and took a sip, saying, "At the Dou Zun level, Earth-rank fighting techniques are already common, and even high-level Earth-rank techniques are not uncommon. If you want to defeat your enemy and catch them off guard when fighting, you must use Heaven-rank fighting techniques."

"But this level of combat skill is profound and obscure. Even though I have a foundation in swordsmanship and movement techniques, it would probably take me several months to comprehend and even begin to understand it."

Upon hearing this, Venerable Tianhuo couldn't help but twitch at the corner of his mouth. He shook his head, stroked his beard, and sighed, "Sect Master, you are really overthinking this. I have wasted hundreds of years and have only ever mastered one complete high-level Earth-rank combat skill. Looking across the continent, how many Dou Zun experts may never even come into contact with the Heaven-rank in their entire lives?"

“High-level Earth-rank combat techniques are already the limit that ordinary Dou Zun experts can reach. Since you have already mastered the Five-Round Fire Technique, which is enough for you to roam freely among Dou Zun, why are you in such a hurry to achieve success and fixated on the Heaven-rank?”

Hei Qing, who was drinking nearby, agreed and said, "I was lucky enough to learn a low-level Heaven-rank body-refining technique. That thing was deadly to cultivate; it almost broke my bones."

"Lu Yu, your expectations are a bit too high. Heaven-rank combat skills aren't so easy to master."

"You're lucky if you can even get one skill. Anyway, you're still young. Take your time to understand it, and you'll eventually—"

Before he could finish speaking, a subtle yet clear fluctuation suddenly came from the space outside the courtyard, and then a pitch-black spatial rift was silently torn open.

The expressions of the people who were talking suddenly froze, and Lu Yu also instantly put away the two jade slips on the table and turned his sharp gaze to the entrance of the courtyard.

Several figures stepped out of the spatial rift one after another.

The leader was a woman dressed in a magnificent palace gown. Her face was gentle and beautiful, but her eyes contained the majesty of someone who had long held a high position and an unfathomable spiritual power. She was none other than Xuan Yi, the giant of the Pill Tower.

Following closely behind was an elderly man dressed in a light blue robe. His figure was graceful, and his aura was as elusive as the wind. He wore a warm smile on his face. He was none other than Venerable Feng of the Starfall Pavilion.

Then stepped forward a young man in black robes carrying a huge black ruler on his back. His brows were filled with the determination and sharpness that came from years of hardship, and he looked like someone who had been through a lot.

Finally, there was an elderly man dressed in a simple white robe. He was solid-looking, vigorous, and had a ruddy complexion. There was no trace of illusion left; he had clearly rebuilt his body and been reborn.

At that moment, Xuan Yi turned around with a smile, gently pulled him in front of her, and affectionately took his arm.

The old man wore a helpless smile, slightly embarrassed, yet unable to refuse, his body radiating the immense pressure of a Dou Zun powerhouse.

Of the four, the young man in black robes stepped forward first. His gaze swept across the group and landed on Lu Yu. His face immediately lit up with surprise and joy, and he exclaimed loudly, "Brother Lu! I've finally found you!"

However, before he could finish speaking, his expression froze, as if he had seen a ghost, and he gasped sharply.

Sensing the undisguised Dou Zun aura emanating from Lu Yu, his eyes widened, and his voice rose considerably as he exclaimed, "You—you—how are you already a Dou Zun?! It's only been a short time!!"
