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

Chapter 15, ranked twenty-third on the Strange Flame Ranking: Earth Core Flame!

After cleaning up the body,
After exchanging pleasantries with the Xiao family members, Lu Yu returned to his room with Little Fairy Doctor.

"How are you progressing with the Jade Butterfly Technique and Purple Smoke Barrier that I taught you before?"

Lu Yu lightly tapped his fingertip, and the flame on the candlestick lit up instantly.

The Fairy Doctor gently waved her hand, and a wisp of purple smoke swirled in her palm: "The Jade Butterfly Technique can now conjure three poisonous butterflies, and the Purple Smoke Barrier is also nearing completion." She lightly turned her wrist, and jade butterflies fluttered faintly within the purple smoke, a truly beautiful sight.

A look of approval flashed in Lu Yu's eyes. In the past six months, besides studying alchemy, he had also conducted six simulations. Two of these simulations were unlucky, encountering unexpected events and yielding nothing.

The other two simulations yielded two high-grade spirit techniques, Jade Butterfly Technique and Purple Smoke Barrier, one offensive and one defensive, which he then gifted to Little Fairy Doctor.

The most surprising thing was that the last two simulations yielded two rare items called Earth Core Jadeite, which contained a deep essence of earth fire, but were also mixed with violent fire poison energy.

If an ordinary person were to absorb it rashly, their meridians would be burned by the violent fire poison it contains. But the strange fire can devour this fire poison along with the essence of the earth fire, turning it into nourishment.

After Lu Yu fed it to the Earth Core Flame, Yao Lao observed it and gave his evaluation: Although the enhanced Earth Core Flame was still not as good as the Bone Spirit Cold Flame in his hand, its power was already comparable to the sub-flames differentiated from some strange flames.

It might even be able to rival the lowest-ranked Strange Flame on the Strange Flame Ranking.

……

The following day, Wutan City was in an uproar.

Six powerful Grand Masters from the Jia Lie and Ao Ba families vanished overnight, leaving no trace of their battle. Rumors spread like wildfire, and whispers filled teahouses and taverns.

"Have you heard? It seems like Galebi was murdered. Last night, that bastard Galeio didn't even bother with any women; he ran away in the middle of the night!"

"The Obama family is even more bizarre. The guards on night watch said they saw a flash of crimson light in the middle of the night, and the remaining elders of the Battle Master class were instantly reduced to ashes..."

Inside the Xiao family's council hall, the three elders wore solemn expressions. The eldest elder lightly tapped his teacup with his fingertips, the bottom of the celadon cup making a soft, tinkling sound on the sandalwood table.

"Have you found out?" the Second Elder asked in a low voice. "It really is that kid..."

"Who else could it be but him?" The Third Elder glanced at the training ground outside the window.

In the morning mist, Lu Yu was instructing Little Fairy Doctor on how to cultivate her fighting spirit. The purple mist dancing in the girl's palm transformed into purple poisonous butterflies, fluttering and dancing in the courtyard.

Exquisite beauty conceals a deadly danger.

"This girl's control over poisonous fighting spirit has become increasingly refined." The Grand Elder narrowed his eyes, his teacup tilting unconsciously, a few drops of tea splashing onto his sleeve without him noticing.

The Second Elder's Adam's apple bobbed, and his voice lowered even further: "The commotion last night... it was at least a battle between high-level Grand Battle Masters. But this kid clearly..."

"He's clearly just a three-star Grand Master..."

The Third Elder picked up the conversation, frowning as he spoke.

A deathly silence fell over the council chamber. The three elders exchanged glances, each seeing a deep sense of apprehension in the other's eyes.

"Alright, whatever you say!"

Xiao Zhan, who was sitting in the main seat, suddenly slammed his hand on the table and stood up, his eyes flashing with a sharp light. "Young friend Lu is a guest of my Xiao family, and we have been on good terms for two generations. This is a golden opportunity. Now that the elites of the Jia Lie and Ao Ba families have been wiped out, it is time for my Xiao family to rise!"

With a flick of his sleeve, he solemnly instructed, "Elder, you will take over the Jialie family market and make sure to control all the pharmacies before noon. Second Elder, the Oba family's mines are now in your hands."

"Third Elder, keep a close eye on the direct descendants of the two major families."

His gaze sharpened, and his voice suddenly turned cold, "Remember, do it cleanly and efficiently."

"Brother Yu, are you really going to the Tagor Desert?"

In a quiet courtyard, Lu Yu was sitting at a stone table, carefully wiping a bronze medicine cauldron, not missing any detail.

Xun'er's voice came from behind, carrying a hint of barely perceptible concern.

Lu Yu put away the medicine cauldron, turned around and smiled, "Well, I heard that a strange fire has appeared there. As you know, I am an alchemist, and strange fires are very attractive to me, so I plan to go and see."

Xun'er nodded, then said with concern, "Then Brother Yu, you must be careful. If things don't go well, leave as soon as possible."

Lu Yu smiled gently and said softly, "Don't worry, I'll be back in six months at most. I don't want to miss the Canaan Academy's admissions."

Xun'er nodded slightly, her long eyelashes casting soft shadows in the sunlight. A hint of reluctance flashed in her eyes, and her voice was as gentle as water: "Brother Yu, you must come back soon. Xun'er will always be waiting for you at the Xiao family."

Seeing the longing in the girl's eyes, Lu Yu's heart warmed, and he almost blurted out that he couldn't go. He composed himself, reached out and gently pulled Xun'er into his arms, whispering in her ear, "I will definitely come back soon."

Not far away, Ling Ying, hiding in the shadows of a corner, watched the two embracing in the sunlight and shook her head helplessly: "This kid... the young lady is so close to him every day, if the clan leader finds out..."

He touched his nose, sighed with a wry smile, but had no good solution.

……

Soon after,

Inside a secluded cave on the back mountain of the Xiao family.

The illusory figure of the old apothecary hovered in mid-air, the Bone Spirit Cold Flame dancing in his palm, enveloping a ball of scarlet liquid. As the flames surged, the liquid condensed, emitting waves of scorching heat.

"Congeal!"

With a low shout from the old apothecary, the Bone Spirit Cold Flame suddenly surged. At the center of the flame, a blood-red pill the size of a dragon's eye spun rapidly, lotus-shaped patterns gradually appearing on its surface. Suddenly, a violent energy surge erupted from the pill, stirring up waves of air within the cave.

"boom!"

This vast energy fluctuation spread outwards, causing the trees outside the cave to sway without wind. The rich aroma of medicine, mixed with the blood-red mist, formed a small red cloud in the sky that lingered for a long time.

Energy ripples—this is a phenomenon that can only be observed when refining pills of grade four or higher!

"It's done." The old apothecary smiled, waved his sleeve to extinguish the flames, and tossed the still-warm blood-red pill to Lu Yu.

Upon seeing this, Lu Yu quickly took out a jade bottle of extremely high quality from his storage ring and then swiftly placed it inside.

"Senior's alchemy skills are truly admirable." Lu Yu carefully put away the jade bottle and sincerely praised, "To think that a fifth-grade Blood Lotus Pill could be refined so perfectly."

The old apothecary stood with his hands behind his back, his white eyebrows slightly raised: "Blood Lotus Essence and Ice Spirit Flame Grass are such rare and hard to come by, yet you're willing to part with them. Is it really for that nonexistent strange fire in the Tagor Desert?"

Lu Yu chuckled, a sly glint in his eyes, and said, "It's better to be prepared."

He said this, but in reality, he had other plans. His true purpose was the Azure Scale in the Tagor Desert and the fragment of the Pure Lotus Demon Flame Map in the hands of Ice Emperor Hai Bodong.

"As for the Azure Lotus Earth Core Flame..." Lu Yu shook his head inwardly. With the simulator at his disposal, he didn't value this kind of low-ranking strange flame very much.

On the contrary, the Pure Lotus Demon Flame, which gives birth to a spirit of a different kind of flame, and Qing Lin's rare Azure Serpent Three-Flower Pupil, are rare even in the Great Thousand World.

As for this Blood Lotus Pill, it was actually prepared for the Little Fallen Heart Flame of Canaan Academy. As long as he cultivates the Floating Pagoda, it will not be difficult for him to contain multiple different flames in the future, so it is good to prepare one in advance.
