Chapter 10: The Real Use of the Simulator, The Rise of a Mere Stable Slave!

Soon after,

When Lu Yu returned to his courtyard and pushed open the gate, an enticing aroma of food wafted towards him.

Inside, the candlelight flickered as Little Fairy Doctor placed the last plate of stir-fried vegetables on the table, the steam rising gently in the candlelight.

"You're back?" She didn't even look up, gently stirring the medicinal food in the casserole with a wooden spoon. "Wash your hands and eat."

On the table were several home-style dishes: stir-fried wild vegetables, refreshing cold blue silver grass salad, fragrant flaming rabbit meat, and a pot of golden and bright pheasant soup.

Looking at the sumptuous dinner before him, Lu Yu smiled and said, "It's rare for Miss Xian'er to cook herself."

Little Fairy Doctor glanced at him, then silently sat down to eat.

"When will we begin our dual cultivation?" she suddenly asked.

"No rush." ​​Lu Yu picked up a piece of rabbit meat with his chopsticks. "You've just mastered the Great Floating Pagoda Technique. Let's wait until you break through to the Dou Shi level to avoid any mishaps."

Little Fairy Doctor nodded, and the two chatted for a few more minutes before returning to their rooms to cultivate. The courtyard quickly returned to tranquility, with only the occasional gurgling sound from the medicine furnace.

Half a month has passed in the blink of an eye.

During this period, Lu Yu studied the Mad Lion's Roar during the day and devoted himself to cultivating the Great Floating Pagoda Technique at night.

Little Fairy Doctor also stayed indoors all day, focusing on studying the Great Floating Pagoda Technique and transforming the poisonous fighting energy within her body. Although the two lived in the same courtyard, they rarely met.

That morning, Lu Yu was practicing "The Roar of the Mad Lion" in the courtyard. He took a deep breath, a faint, eerie light swirling in his throat, and then let out a low roar—

"Roar!"

The sound waves materialized, transforming into the majestic head of a golden lion. Wherever the sound waves passed, the air distorted and trembled, the branches and leaves of the old trees in the courtyard rustled and fell, and the birds in the distant forest fell like raindrops.

"Phew—" Lu Yu let out a long sigh, his fingertips lightly touching his throat. The cool sensation of the Ice Spirit Throat-Protecting Liquid still lingered there: "I've finally mastered it. If it weren't for this spiritual medicine, I'm afraid it would have taken me another three months to even get started."

"There is indeed a reason why alchemy can be so popular in the Dou Qi Continent."

"However, a month has passed, it's time for the simulation."

Lu Yu pondered for a moment, then looked around and found that there was no one around.

Xiao Yan and Yao Lao went to the back mountain of the Xiao family to cultivate, while Little Fairy Doctor went out to the Xiao family market to buy daily necessities. It was a good time for him to simulate.

He hurried back to his room and closed the door behind him. The candlelight by the window flickered slightly in the breeze. He sat cross-legged, took a deep breath, and his mind stirred—

A pale blue light screen slowly unfolded before my eyes like ripples on water, coalescing into lines of text.

[The simulation count has been refreshed. The current simulation count is one. Do you want to start the simulation?]

"Turn on!"

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

[Selection successful. Please choose one of the following three roles.]

[One, Mercenaries of the Northern Spirit Realm—You were born into poverty, the offspring of a pair of mercenaries from the Northern Spirit Realm of the Hundred Spirits Continent. Abandoned by your parents at a young age, you were fortunate to be taken in by a kind old man.]

[Second, a student of the Northern Spirit Academy—You are a rare cultivation genius in the Northern Spirit Realm. At the age of eleven, you sensed spiritual energy and entered the Northern Spirit Academy, the best academy in the Northern Spirit Realm, becoming a disciple of its East Courtyard.] [Third, a stable boy of the Liu family—You are from the Liu Region, one of the nine major domains of the Northern Spirit Realm. Due to an accident, you were sold into slavery by the Liu family to raise their black-scaled horses.]

Please make your choice——

"This simulated identity was much worse. I was too lucky the first two times, and it's rare for me to have such bad luck."

Looking at the three identities drawn in this simulation, Lu Yu shook his head helplessly. He also wished he could have a wonderful start with a Supreme or even Earthly Supreme background every time.

However, even the Supreme Being is a powerful being in the vast world, so such a beautiful dream is probably not something that happens often.

"Mercenaries are definitely out of the question. Choosing one would leave you completely clueless, and you might just die in some remote corner. The Liu family is probably the small family that opposes Mu Chen; they're definitely villains, so we can't choose that either. We can only choose option two."

Lu Yu pondered for a moment, just about to choose the identity of a student of the Northern Spirit Academy, when suddenly a thought struck him. He narrowed his eyes and secretly calculated, "That's not right. Judging from the results of the previous two simulations, I should have all the memories of my real self in the simulation. Otherwise, I wouldn't have risked my life to obtain the Yang and Yin scrolls of the Great Floating Pagoda Technique."

"In that case, he should know everything I know. I'll leave aside the special fighting technique, Purple Cloud Wings, but he's probably also proficient in things like Roar of the Mad Lion, Guardian Palm, and alchemy."

Lu Yu's breathing quickened as he thought about this. If that were the case, although cultivation levels couldn't be shared, memory sharing meant that the more he knew in reality, the stronger he would be in the simulation!
The stronger you are in the simulation, the greater the benefits you can bring to your real-world self.

In this way, the two help and promote each other, and even if they draw a slightly worse identity in every simulation, they can still defy fate!

"This is the true way to use an emulator..."

Excitement ignited in Lu Yu's eyes. He re-examined the three options, his gaze finally settling on [Liu Family Stable Worker].

"If we're going to play, let's play big," he chuckled softly. "Let's start with the Liu family."

"I hope I won't disappoint in the simulation..."

[Selection successful! Identity loading...]

[Simulation begins——]

In the first year, a rare beast tide broke out in Willow Domain. Your parents died in battle defending the city, your uncle seized your family's property, and sold you into slavery to the Willow family.

[In the second year, you were assigned to the stables to raise the low-level spirit beast, the Black-Scaled Horse. Resentful, you secretly began cultivating the high-grade spirit-level technique, the Flame-Making Art, in an attempt to defy fate.]

[In the third year, your cultivation broke through to the Spirit Realm. Coincidentally, Liu Yang, the second young master of the Liu Region, returned from the Northern Spirit Academy and was preparing to select followers. Because of your young age and outstanding talent, you were arranged by the eldest young master, Liu Mubai, to be by Liu Yang's side and enroll in the Northern Spirit Academy together.]

[In the fourth year, thanks to the Spirit Gathering Array of the Northern Spirit Academy, your cultivation broke through to the late stage of the Spirit Movement Realm before Liu Yang. In the academy's examination for Earth Realm students, you astonished everyone with your Guardian Palm and Mad Lion's Roar, becoming the top Earth Realm student and making a name for yourself in the Northern Spirit Academy!]

[Subsequently, your two high-grade spirit-level techniques of unknown origin aroused suspicion from the Liu family.]

[You should know that in this vast world, below the Supreme level, the cultivation techniques practiced are divided into three levels: Mortal, Spirit, and Divine. Each level is further divided into three grades: Upper, Middle, and Lower. A single Upper-Grade Spirit Technique is worth millions of Spirit Coins; even the Liu Family's clan-protecting cultivation technique is worth less!]

However, since you have already become a student of the Heavenly Realm, the Liu family has not acted rashly.

[In the second month, the Northern Spirit Academy arranged for its Heavenly Realm students to go to the Northern Spirit Plains for training. Liu Mubai, the eldest son of the Liu family, asked you to accompany him, but you refused, which displeased him greatly.]

[In the third month, during your hunt for spirit beasts in the Northern Spirit Plains, you encountered an ambush by the Blood Slaughter Mercenary Group. Although they did not reveal their identities, you, with your memories from your previous life, know that they are one of the lackeys trained by the Liu family.]

[Subsequently, you stopped deliberately suppressing your cultivation, broke through to the Spirit Wheel Realm, killed the Blood Slaughter Mercenary Group, and found the Nine Nether Bird's hiding place on Blood Slaughter, thus seizing this opportunity ahead of time.]

[In the fourth month, Liu Mubai led a group to ambush you, attempting to retrieve the map of the Nine Nether Sparrow's hideout. You killed him in public and stole his storage artifact—the Mustard Seed Bracelet.]
