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

Chapter 77 Taking stock of the spoils, another simulation

In the dead of night, Lu Yu returned to his room after playing around with Zi Yan and Xiao Yi Xian.

He fell into a deep sleep as soon as his head hit the pillow. Although the Burning Heaven Spirit Secret Technique had not damaged his core, the fatigue from traveling for days and the depletion of his fighting spirit still left him feeling weak all over.

The next morning,

The clear chirping of birds came from outside the window. Lu Yu slowly opened his eyes. Just as he sat up, the door was gently pushed open.

"Woke up?"

Little Fairy Doctor walked in carrying a bowl of medicinal soup. Steam rose from the bowl, and a few slices of ginseng could be vaguely seen floating in the milky white liquid.

She placed the soup bowl on the bedside table and said softly, "This is a soup made with spirit mushrooms that has been simmering for three hours. I've added snow ginseng and nourishing herbs. Drink it while it's hot."

Lu Yu propped himself up, took the soup bowl, tilted his head back and drank it down in one gulp. As the soup entered his throat, a warm current flowed to his limbs and bones, and even his exhausted meridians felt a comfortable hum.

"Where is that girl Ziyan?"

Lu Yu wiped the soup stains from his lips and glanced around the courtyard, only to find it eerily quiet.

Little Fairy Doctor smiled slightly, a hint of amusement flashing in her eyes, and said, "Last night that girl kept pestering you for pills, and this morning the effects took hold, so she's sleeping soundly in the side room right now."

"What are your plans next?"

"Should we proceed with the original plan and continue preparing for seclusion at the Heavenly Flame Qi Refining Tower?"

"Let's postpone it for now."

Lu Yu shook his head slightly, his expression somewhat solemn, and said, "Continuously using the Heaven-Burning Spirit-Burning Secret Technique for three days without interruption has no side effects on me, but it has consumed too much of the Earth Core Flame. I'm afraid this strange fire can no longer be used easily in the short term."

"Let's wait until Vice Dean Hu Qian brings the Origin Heart Flame before we talk about it..."

After a brief pause, Lu Yu continued, "I plan to use this time to thoroughly study the fighting technique that Xun'er gave me."

"By the way, I am now an honorary elder of the academy, and the academy's exchange system has been activated for me. If you need any resources for your cultivation, you can take a look at this."

As he spoke, Lu Yu handed a booklet to Little Fairy Doctor, which was the exchange manual that Hu Qian had given him earlier.

Little Fairy Doctor took the exchange manual, her slender fingers gently tracing the gold-embossed pages. Her gaze, sharp as lightning, quickly swept over the various rare medicinal herbs, finally settling on two fifth-tier poisonous plants.

"Poisonous Dragon Grass, Bone-Corroding Flower..."

She murmured softly, her fingertip pausing slightly at the price tag of two thousand fire energy points, and said hesitantly, "These two poisonous herbs are very beneficial to my cultivation, but the price..."

Lu Yu smiled upon hearing this and said, "Don't worry, I'll start refining pills in the next few days, and I'll earn back the mere four thousand fire energy points very quickly."

He pointed to the storage ring on his hand and said, "Have you forgotten that we still have a few sets of materials for refining the Purple Heart Breakthrough Pill that we haven't used yet?"

A ripple appeared in Little Fairy Doctor's eyes. Just as she was about to speak, she saw Lu Yu take out two ancient-looking storage rings and place them on the table.

"Let's take a look at these spoils of war first."

He was the first to open the Blood Sect's Fourth Elder's storage ring, and all sorts of miscellaneous items poured out.

Lu Yu's slender fingers rummaged through a pile of miscellaneous items, suddenly stopping in front of a small black jade bottle. The bottle was wrapped in blood-red runes, and as soon as it was opened, a strong stench of blood wafted out.

"Level 5 deadly poison..."

Lu Yu carefully examined the dark red liquid in the bottle, frowning as he said, "It seems to be made from a mixture of the essence blood of various magical beasts..."

Little Fairy Doctor's eyes lit up. Lu Yu, understanding, handed her the bottle and said, "See if you can use it..."

The Little Fairy Doctor carefully took the black jade bottle, her slender fingertips gently caressing its surface. She tilted the bottle slightly, and the dark red venom gleamed eerily in the sunlight.

"This was made from the blood of at least seven highly venomous magical beasts..."

Her nostrils twitched slightly as she carefully discerned the scents, calling out each one in turn: "Blood-Eyed Demon Spider, Azure Phosphorous Serpent, Bone-Eating Toad..." With each name she uttered, her eyes brightened a little more.

Looking at her focused profile, Lu Yu couldn't help but smile and say, "Looks like you've struck gold?"

"It's more than just a treasure."

Little Fairy Doctor rarely showed such joy, and said happily, "This bottle of blood poison combines the essence of the blood poison of three fifth-tier magical beasts and four fourth-tier magical beasts. Combined with my Calamity Poison Body cultivation, it can save me at least a year of arduous training."

She gently shook the dark red liquid in the bottle and said happily, "I won't have to worry about cultivation resources anymore before I break through to the Dou Wang level."

Lu Yu chuckled upon hearing this: "That's excellent. If you combine this with the cultivation of the Heavenly Flame Refining Tower, your cultivation speed can increase several times over."

He pondered for a moment and said, "If we calculate it this way, you might be able to break through to the Dou Wang level in less than half a year."

Then he took out the storage ring from the Black Skull Tomb, only to find that the items inside were significantly inferior to those in the Blood Sect, practically worthless.

Only one dark yellow ancient book stood out. The four ancient seal characters on the cover, "Corpse Puppet Hundred Refinements," twisted like earthworms, exuding a chilling aura.

"Puppetry Techniques?"

Lu Yu quickly flipped through the pages, his brows furrowing as he pondered, "It requires living corpses as materials. After successful refining, the cultivation level will drop by two to three stars. It also requires continuous consumption of rare and precious materials with yin and cold attributes to maintain its vitality..."

"No wonder this guy is so poor; this Corpse Puppet Technique is a real money pit..."

He closed the booklet, shook his head and sighed softly, but then thought better of it and put it into his storage ring.

"Well, something is better than nothing, something is better than nothing."

As for the rest of the miscellaneous items, he categorized them and stored them in his unused storage rings.

……

A few days later,

The courtyard was quiet. Little Fairy Doctor stayed inside, focusing on refining the bottle of blood poison.

Lu Yu sat alone in the quiet room. With a thought, a pale blue light screen slowly unfolded in front of him.

"It's time for simulations again."

"This simulation not only requires finding the ingredients for the Bright Soul Pill, but also inquiring about the whereabouts of the Azure Jade Lotus Root..."

“These things are hard to find, especially the Azure Jade Lotus Root. As a treasure that can reshape the physical body, even supreme experts covet it…”

"However, for Earthly Sovereign level experts, this item is somewhat of a double-edged sword. After all, at that level, the Supreme Sea has completely merged into their flesh and blood. As long as there is a sliver of life left, they can repair their bodies on their own, making them almost immortal..."

"There's no point in overthinking it. Let's draw a simulated identity first."

As soon as Lu Yu had a thought, the light screen in front of him began to change, and lines of text began to appear in his mind.

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