Chapter 123 Han Feng, the Medicine King? Xiao Yan of the Xiao Family!
After the matter was discussed,

Lu Yu then led Zi Yan and Cai Lin away from the Elder Council Hall. Dusk had fallen, and the three walked slowly along the tree-lined path in the inner courtyard, heading towards their residence.

Soon, the familiar courtyard gradually came into view. Before even stepping into the courtyard, one could hear the crisp sound of a spatula stirring inside.

"Qinglin, pass me the spices." Little Fairy Doctor's gentle voice drifted from inside the courtyard.

"Here you go, Little Fairy Doctor." Qinglin responded obediently, while the little flower on her wrist flicked its tongue, seemingly also attracted by the aroma of the food.

An enticing aroma filled the entire courtyard, the rich savory flavor of braised pork, the fresh aroma of steamed fish, and the delicate fragrance of freshly cooked rice, making one's mouth water.

Zi Yan's eyes lit up, and she rushed into the yard in three steps: "It smells so good! What delicious food did you make today?"

Little Fairy Doctor came out of the kitchen carrying the last plate of vegetables and said with a gentle smile, "These are all your favorites. Go wash your hands and get ready to eat."

Looking at this heartwarming scene, Cai Lin's cold and beautiful face softened a little.

As night fell, after dinner, everyone went back to their rooms to rest. Cai Lin and Qing Lin moved into the left wing room, while Zi Yan took Xiao Yi Xian to the right guest room. Lu Yu remained in the main house.

A few days later, just as dawn was breaking, Lu Yu was practicing his breathing exercises in the courtyard. Suddenly, a series of urgent knocks sounded through the morning mist.

"Bang bang bang!"

The courtyard gate opened with a sound, and a tall, slender figure dressed in a black robe stood in the morning light.

"Brother Lu..."

The familiar voice made Lu Yu open his eyes abruptly. The person who had just entered lifted his hood, revealing a handsome and refined face. Although there was a hint of weariness from his journey, his eyes were still bright and piercing.

"Brother Yan? You're back from the Black Corner Region?"

Lu Yu stood up in surprise and quickly went to greet him.

Xiao Yan raised the corners of his mouth slightly, revealing a familiar smile, and explained, "I received an emergency summons from the academy, so I rushed back overnight."

"Come in and sit down." Lu Yu stepped aside to open the courtyard gate.

Xiao Yan stepped in, the hem of his black robe still carrying traces of dust.

Lu Yu scrutinized him closely, a hint of surprise flashing in his eyes. He said, "It seems you've gained quite a bit from this training trip. You've actually broken through to the Seven-Star Great Dou Master level?"

Xiao Yan smiled and nodded, saying, "I encountered some fortuitous opportunities in the Black Corner Region, but besides matters concerning the academy, there's something else I'd like to ask Brother Lu for help with..."

"Oh?"

Lu Yu raised an eyebrow and joked, "That's strange. It's rare for you to ask me for a favor. What's the matter?"

Xiao Yan touched his nose and said softly, "I discovered a Dou Zun ruin in the Black Corner Region..."

Lu Yu's expression hardened, and with a light wave of his right hand, an invisible energy barrier instantly enveloped the entire courtyard.

He gave Cai Lin a look, who nodded in understanding and turned to walk out of the courtyard to stand guard.

After a while,
The aroma of tea wafted around the stone table, and Little Fairy Doctor poured a cup of clear tea for each of them; the tea soup was crystal clear.

Xiao Yan took out a fragment with a bronze luster from his storage ring and carefully placed it on the stone table, saying, "I found this in an ancient tomb. It records the approximate location of the ruins."

The fragment was engraved with obscure and ancient runes, with a fragmented flame emblem faintly visible at the edge. The moment Lu Yu received the fragment and his fingertips touched it, the three strange flames within his body simultaneously stirred restlessly.

"This is... the aura of a strange fire?" Lu Yu suddenly looked up.

"good."

Xiao Yan's gaze was intense as he lowered his voice and said, "I suspect that this ruin may contain clues to the Yin-Yang Twin Flames..."

He paused, then added solemnly, "If we can find the strange fire, I only want the strange fire; all the other treasures will belong to Brother Lu."

Upon hearing this, Lu Yu focused his gaze and saw a mysterious Tai Chi pattern engraved on the surface of the fragment, with a black and white interwoven flame pattern faintly emerging in the center of the pattern.

He stroked his chin, and after a long while shook his head and sighed softly, "Your luck is truly..."

"However, I also have things to do during this time, and I need to finish my work at the academy before I can accompany you to explore this ruin..."

"Now that you've confirmed it's a Dou Zun relic, have you investigated this Dou Zun's background? Do you know the origin of his name?"

Xiao Yan nodded, his expression grave. "I secretly visited several intelligence organizations in the Black Corner Region and found out some information. This Dou Zun powerhouse, who is known as the 'Yin Yang Venerable'..." He paused slightly, then continued, "It is said that he has a strange temperament and his behavior is quite... vile."

"bad?"

Lu Yu frowned slightly and asked, puzzled, "What kind of evaluation is this?"

Xiao Yan's expression turned somewhat strange as he explained, "It is said that this Venerable One is a human-snake hybrid, with a thin layer of snake blood flowing through his veins, and..."

He lowered his voice, "He has a peculiar hobby, especially an obsession with snake-like magical beasts."

"Obsessed with snake-like magical beasts?"

Lu Yu raised an eyebrow and asked, "What kind of strange hobby is this?"

Xiao Yan quickly explained, "It's not the ordinary kind of fondness. This Venerable One... is particularly enthusiastic about torturing and killing snake-like magical beasts, and then making specimens of certain organs for his collection..."

Lu Yu fell silent.

Good heavens, he originally thought it was another snake-riding warrior, but he never expected it to be such a monster...

After a while,

Lu Yu slowly shook his head, then said, "Since that's the case, I already know the details. I also have something I'd like to tell you..."

"But the final decision is entirely up to you."

Upon hearing this, Xiao Yan was taken aback, then asked, "Brother Lu, what is it?"

Lu Yu looked directly at him and said, word by word, "Do you know... the Medicine King Han Feng?"

"Crack!"

The teacup in Xiao Yan's hand shattered with a crack, tea dripping through his fingers. His face instantly turned ashen, and a chilling killing intent unconsciously emanated from him.

"Brother Lu...why did you suddenly bring this person up?"

Lu Yu said with a solemn expression, "In a few days, there will be a major change in the academy. This person... is very likely to make a move against the academy."

"As far as I know, this person possesses the Sea Heart Flame, ranked fifteenth on the Strange Flame Ranking. I know you cultivate the Burning Technique and lack a Strange Flame..."

"Therefore, I am informing you of this person's whereabouts."

Upon hearing this, Xiao Yan stroked the black ring on his hand and remained silent for a long time.

After a moment of silence, Xiao Yan looked up and said, "Brother Lu, if this person comes to offend the academy, I hope you can spare his life..."

"Oh?"

Upon hearing this, Lu Yu's eyes flashed with surprise, and he asked, "Why is that?"

Xiao Yan's fist clenched involuntarily, his knuckles turning white. His voice was low, yet contained a chilling killing intent as he said, "This man is my senior brother. The reason our teacher ended up like this was all thanks to him. I once swore to our teacher that I would personally cleanse him of his sins..."

"This man must be killed!"

Lu Yu raised an eyebrow slightly and said calmly, "This is simple. If he dares to come, I will capture him and hand him over to you."

"Do not."

Xiao Yan shook his head, his eyes burning with a stubborn flame, and said, "I want to defeat him fair and square, and prove with my strength that my teacher's judgment was correct."

"I want him to understand what he missed back then!"

Looking into Xiao Yan's determined eyes, Lu Yu sighed inwardly. He understood that this young man possessed an indomitable spirit, pride, and unwavering principles.

Although the safest course of action for him would be to deal with Han Feng directly with his current strength, doing so would hurt Xiao Yan's pride.

Thinking of this, Lu Yu's gaze inadvertently drifted to the antique black ring on Xiao Yan's finger.

It remains to be seen whether this Medicine Master, who is pretending to be asleep, will be able to continue to hold back from making a move...

Compared to Yan Di's persistence, this guy is way too shameless...
