While the player is in Battle Through the Heavens, the system is in The Great Ruler.

Chapter 18, another simulation, and incredible luck—a disciple of the Endless Fire Domain!

The night was as dark as ink, and the bright moonlight shone through the window screen, casting a silvery frost over the room.

On the bed, two figures sat facing each other. Lu Yu's body was surrounded by crimson battle qi, while Xiao Yixian's body was shrouded in purple mist. The two completely different battle qi perfectly merged in a small space, forming a slowly rotating energy vortex.

Suddenly, Lu Yu frowned slightly, and a muffled thunderous roar emanated from his body. Crimson waves burst forth from his body, condensing into a faintly visible battle aura armor on his skin.

A violent energy surge swept across the entire room, and the teacup on the table cracked with a "crack" as several fine lines appeared.

"Four-star Grand Dou Master..." Lu Yu slowly exhaled a breath of turbid air, his eyes flashing with a sharp light.

Almost simultaneously, Little Fairy Doctor's delicate body trembled slightly, and the poisonous mist surrounding her suddenly contracted. Purple lines faintly appeared beneath her fair skin, and ultimately all the poisonous gas converged into the poison pill in her dantian. A chilling aura spread out, corroding the dust on the ground, creating tiny holes.

"Two stars?" Lu Yu raised an eyebrow.

Little Fairy Doctor's lips curled up slightly, a sly glint in her purple eyes: "Likewise."

Under the moonlight, the two looked at each other and smiled.

Lu Yu suddenly sighed softly: "Speaking of which, your Calamity Poison Body is truly astonishing. At this rate, I'm afraid your cultivation will surpass mine in less than half a year."

"Don't give me that," Little Fairy Doctor scoffed, twirling a strand of hair between her slender fingers. "The Dual Cultivation Great Floating Pagoda Technique clearly benefits you the most. No matter how strong my poisonous body is, doesn't it still benefit you?"

Lu Yu shook his head and smiled bitterly: "I am just a mortal. If it weren't for the Great Floating Pagoda Technique, I would probably still be struggling in the Dou Shi realm."

Little Fairy Doctor suddenly leaned forward, a sly glint in her purple eyes: "Mortal body?" She gently lifted Lu Yu's chin with her slender fingers, her red lips slightly parted: "Then... how about I take care of you?"

Under the moonlight, her purple eyes gleamed with a hint of mockery: "Once I become a Battle King, I'll carry you, this little newbie, through the skies every day, how about that?"

Lu Yu chuckled and took her wrist in the process: "Alright, then I'll be waiting for you to break through soon, so I can live off you."

"This is what you said..."

Before Little Fairy Doctor could finish speaking, she suddenly felt someone's warm, large hand move slightly, and her face instantly flushed red. She hurriedly pulled her hand back, but accidentally knocked over a teacup on the table.

"boom!"

The sound of a teacup falling to the ground broke the ambiguous atmosphere. Little Fairy Doctor hurriedly turned around, pretending to straighten her sleeves to hide her panic: "It's all your fault."

Lu Yu gazed at her flushed earlobes, a faint smile flickering in his eyes, and said softly, "This isn't my fault. It was someone who first offered to be my sugar daddy..."

Upon hearing this, Little Fairy Doctor's purple eyes flashed with a hint of embarrassment and anger: "Who, who wants to take care of you!" Although her tone was fierce, she couldn't hide the slight tremor in her voice.

The moonlight, like water, filtered through the window curtains, casting a hazy shadow on her delicate profile. Lu Yu unconsciously took a step closer, the unique medicinal scent emanating from the girl filling his nostrils. Little Fairy Doctor instinctively stepped back, only to find her back pressed against the cold wall.

Their breaths mingled, exceptionally clear in the quiet room. Little Fairy Doctor's purple eyes shimmered with tears, her red lips parted slightly as if she wanted to say something, but ultimately remained silent.

After an unknown amount of time, Lu Yu sighed softly and took a step back to create some distance: "It's getting late."

He turned and walked towards the door, paused at the doorway, and said, "We have to travel tomorrow, so get some rest."

Little Fairy Doctor watched his departing figure, bit her red lips lightly, and said with a hint of resentment, "I gave you a chance, but you were useless, you coward..."

……

After returning to his room, Lu Yu sat cross-legged on the bed, and a pale blue light screen slowly unfolded before his eyes.

"It's simulation time again," he thought to himself, his fingertips unconsciously tapping his knees. "The main goal this time is to find a way to break Hai Bodong's seal. A safe academy-style opening will be enough."

After a year of simulation experience, Lu Yu had figured out some of the patterns in simulators and summarized three main simulation approaches:
The first type, the adventurer's path, is the most dangerous. Players often start with a lowly status and can only rely on their foresight to survive. While they may occasionally obtain rare items like the Earth Core Flame Elixir, a single misstep can lead to their demise.

The second option, the "academic route," is the safest. In ten out of twelve simulations, there's a choice of student status. This route has the highest survival rate, but the cost is a limited range of rewards and a high likelihood of repeating the same path; it can be described as low risk, low reward.

The third type is background flow...

Such a start is rare and hard to come by, just like the "illegitimate son of the King of the Hundred Spirits" identity he drew last month. Not only was he safe and secure, but he also obtained a valuable item like the Earth Core Jade Marrow, which allowed the Earth Core Flame to successfully evolve.

Unfortunately, this kind of good luck has only happened twice in the past year.

"There's no point in overthinking, let's begin the simulation."

After reviewing his previous simulation experience, Lu Yu had an idea and chose to begin.

[Ding! Extracting a simulated identity for the host—]

[Successfully selected. Please choose one of the following three roles.]

[One, The Son-in-Law of the Luo Shen Clan—You are a natural-born vessel for the Luo Shen Clan, adopted by them at a young age. You grew up with Empress Luo Li of the Luo Shen Clan, and after reaching adulthood, you married into the clan, becoming the enviable son-in-law of the Luo Shen Clan.]

[Second, Disciple of the Endless Fire Domain—You are from a branch of the Xiao family, a disciple from the outer domain of the Endless Fire Domain, and grew up in the Endless Fire Domain from a young age, enjoying a privileged upbringing.]

[Third, Northern Cang Spiritual Academy's guaranteed admission student—You were born with a Heavenly-level spiritual vein. Upon entering the Spiritual Path, you were sought after by the five major academies. Ultimately, you chose the Northern Cang Spiritual Academy, thus exempting you from the Spiritual Path trials and granting you core student status, guaranteeing your admission.]

Please make your choice——

"hiss……"

"I got a gold medal! I even started with the identity of the Endless Fire Domain!"

Lu Yu's eyes lit up, and he couldn't help but slap his thigh excitedly.

This is the Endless Fire Domain!
It should be understood that the world is vast and boundless, and there are countless forces above the Supreme level. Among them, there are probably only a few hundred forces with a Heavenly Supreme in charge.

Among the super powers with Saint-level experts, the human race, apart from the five ancient god races, only has a handful of other super powers such as the Endless Fire Domain, Martial Realm, Sword Domain, Land of Ten Thousand Tombs, and Great Thousand Palace.

To be able to draw the Endless Fire Domain among so many forces is a one in a billion chance!
"What's there to hesitate about? Let's go to the Endless Fire Domain!"

Lu Yu took a deep breath, and with a thought, directly chose the second identity to start the game.

[Selection successful! Identity loading...]

[Simulation begins——]

[In your first year, you turned six. Due to your excellent talent for cultivation, your parents sent you to the Earth-Rank Academy. Because you were in the Endless Fire Domain, you were not afraid of the trouble from the Ancient Buddha Clan. You did not cultivate the divine-level spiritual technique given to you by your parents. After reaching the Spiritual Movement Realm, you directly began to cultivate the Great Buddha Technique, and your cultivation speed increased by leaps and bounds.]

[In the second year, relying on your mastered Guardian Palm and Roaring Lion techniques, you repeatedly won first place in the academy's grand competition, earning the reward of a top-grade Spirit Nourishing Pill. Your cultivation broke through to the Spirit Wheel Realm, and you were sent to the Heavenly Rank Academy for further training.]
