Chapter 144 The Resurrection of the Medicine Master, Han Feng's Regret!
"Junior brother!"

"I only ask for a way to live!"

Han Feng suddenly roared and exerted force with his five fingers, crushing the neck of the Demon Flame Valley disciple in his hand.

"Don't force me to fight to the death!" His eyes revealed a murderous intent.

Before he finished speaking, a fierce glint flashed in Han Feng's eyes. His deep blue battle qi erupted like a raging tide. With a single palm strike, he unleashed a roaring sound, and a giant fire dragon formed from Qianlan Water Flame charged out.

This sixth-tier beast fire was specially found for him by Demon Flame Valley to assist him in refining pills during this period.

"Crack!"

Faced with Han Feng's sneak attack, Xiao Yan remained calm and unhesitatingly crushed the Blood Burning Pill in his mouth. In an instant, his aura surged from the Seven-Star Dou Ling level to the peak of the Nine-Star Dou Ling level. Immediately afterward, his hands swiftly formed hand seals, and the earthen-yellow Wind Fury Dragon Flame instantly covered his entire body.

"The first of the Three Mysterious Transformations of Heavenly Fire: The Fury of Wind!"

"boom!"

The violent fire-attribute energy surged through his meridians, and Xiao Yan's aura surged once again, breaking through the Dou Ling barrier in one fell swoop and reaching the three-star Dou Wang realm!

"Baji collapse!"

With a single punch, the wind-swirling dragon flames of the fist transformed into an earth-yellow fire tornado. Within the tornado, lava-like fire swirled wildly, distorting and deforming the air in its path, emitting a hissing, scorching sound.

"Roar!"

The fiery tornado and the blue dragon collided violently in mid-air, unleashing a deafening roar. The two distinctly different fiery energies tore at each other, casting flickering light and shadow over the entire secret passage.

Han Feng's expression changed drastically. He was shocked to find that the Azure Water Flame he had unleashed with his Dou Huang cultivation was being steadily defeated by this Dou Wang junior brother!

"Damn it!"

"If my Sea Heart Flame still burns, how dare you be so arrogant!"

Han Feng's face contorted, and with a swift wave of his sleeves, more azure flames erupted, forming layers of fire walls in front of him.

Xiao Yan's killing intent intensified. He stomped his foot and moved like a ghost through the aftershocks of the explosion, unleashing another Eight Extremes Collapse attack, this time imbued with the fury of wind and dragon flames, aimed straight for Han Feng's heart!
"boom!"

In his haste, Han Feng managed to conjure a blue fire shield in front of his chest. However, the moment the shield made contact, it tore apart like paper. A terrifying force pierced through his body, sending him flying backward and crashing heavily out of the passage.

"puff……"

Han Feng staggered back several feet, spitting out a mouthful of blood. He raised his hand to wipe the blood from the corner of his mouth, his eyes fixed on the strange fire in Xiao Yan's hand, a fierce glint in his eyes.

Immediately, he clenched his fist, and the azure flames rapidly condensed, eventually transforming into a solidified azure trident.

Gripping the flaming trident, which was over two zhang long, Han Feng's confidence grew. He coldly stared at Xiao Yan, who was walking out of the passage, and sneered, "Junior brother, how long can your cultivation level, which you forcibly increased through secret techniques, last? Today I'll show you that fighting beyond your level isn't something everyone can do!"

As soon as he finished speaking, a powerful surge of azure flames erupted from Han Feng's body. As the flames surged, the trident instantly grew several meters in size, with the blazing azure flames on its surface rolling endlessly, emitting a deafening roar like ocean waves.

"You've courted your own death, so don't blame me!"

Sensing the terrifying power contained within the trident, Han Feng advanced instead of retreating, his figure transforming into a fiery dragon-like beam of light as he shot towards Xiao Yan!

"clang!"

Xiao Yan calmly took out the Xuan Heavy Ruler, his expression serene. The giant ruler in his hand instantly created countless afterimages, each imbued with a scorching gust of wind, completely deflecting Han Feng's attacks. This defense was so sharp and seasoned, clearly honed through countless trials.

The fight with Brother Lu a while ago wasn't for nothing!

"Damn, how come this kid's fighting style is so cunning..."

Han Feng's face was gloomy. He wielded his trident, creating afterimages, but he was still unable to break through Xiao Yan's impenetrable defense.

"boom!"

Another fierce collision ensued, the violent force traveling along the halberd's shaft. Han Feng was horrified to discover that his trident, formed from beast fire, was now covered in spiderweb-like cracks. With a crisp sound, the trident shattered!
"Not good!" Han Feng's expression changed drastically, and he hurriedly released the halberd handle, trying to retreat.

However, how could Xiao Yan miss this opportunity?

"call out……"

The Xuanzhong Ruler came hurtling through the air with a sharp whooshing sound and slammed heavily into his chest.

"puff!"

Spitting out a mouthful of blood, Han Feng flew backward like a kite with a broken string, crashing heavily to the ground. He struggled to his feet, his chest caved in, countless ribs broken.

"Cough cough..." Han Feng trembled as he took out a blood-red pill from his waist, a look of struggle flashing in his eyes. But seeing Xiao Yan approaching step by step, he finally swallowed it in one gulp.

"boom!"

As soon as the pill entered his stomach, Han Feng's blood boiled instantly. Violent battle qi surged from his body, even distorting the surrounding air.

"You forced me to do this, junior brother..."

Han Feng's face contorted as he rapidly formed hand seals. A surge of battle energy condensed in his palms, emanating a chilling aura.

Sensing the sudden increase in Han Feng's aura, Xiao Yan took a deep breath, and his body suddenly shone with starlight, as a mysterious and unpredictable energy fluctuation surged from within him.

In an instant, countless brilliant starlight burst forth from every pore of his body, and the surrounding天地能量 (heaven and earth energy) seemed to be drawn in, frantically converging towards him.

"Open the pulse!"

The energy of heaven and earth converged wildly, continuously pouring into the Xuanzhong Ruler. The pitch-black ruler gradually turned into an earthy yellow color, and the temperature rose sharply.

Han Feng's face contorted instantly, and he roared hysterically, "Damn it, how do you still have a trump card!"

"Just how many good things did that old man give you?!"

"Die! Die!"

He frantically channeled his battle qi, and the dazzling ball of light gathered in his palm suddenly erupted, transforming into a brilliant beam of light that shot out into the sky, "Radiant Seal!"

Within that beam of light, a gigantic handprint, obscuring the sky and the sun, could be vaguely seen, like a falling blazing sun, distorting space wherever it passed.

"Flame Devouring Wave Ruler!"

Xiao Yan's expression was solemn. He slashed down with both arms, and a ten-zhang-long earthen yellow ruler light burst out of the air with a rainbow-like momentum, as if it would split the heavens and the earth!

"boom!!!"

Two terrifying energies collided in mid-air, unleashing a deafening roar. The energy ripples swept in all directions, shattering the surrounding stone walls.

As the smoke cleared, Han Feng collapsed to his knees, covered in blood. He looked up in horror to see the Xuan Heavy Ruler pressed against his forehead, its cold surface radiating an aura of death.

"Junior Brother..." Han Feng's voice trembled, "I was wrong... spare my life..."

Xiao Yan remained expressionless, slowly pressing down with the heavy ruler in his hand. Han Feng's skull cracked under the weight, and blood seeped from his seven orifices.

"When you betrayed your teacher back then, did you ever imagine this day would come?"

Xiao Yan's voice was icy cold, "What you did in the past is now reaping what you've sown. You deserve to die, Han Feng!"

"No...don't kill me!" Han Feng's eyes widened in terror as he pleaded incoherently, "Junior brother, I have many treasures here...a sixth-grade medicine prescription, the Yin-Yang Profound Dragon Pill...it's all yours..."

"I know I was wrong! Let me see my master!" he cried hysterically. "I was raised by my master, he would never want me to die... Let me see him..."

"Crack!"

The heavy ruler fell mercilessly, and Han Feng's mouth twisted and deformed instantly, with broken teeth and blood splattering out.

"You dare mention teachers?!"

Xiao Yan's anger intensified, and the thought of Yao Lao's elusive remnant soul fueled his murderous intent.

“It’s time to end this,” he said coldly.

"Waaah..." Han Feng let out a reluctant sob, a hint of despair flashing in his eyes.

Just as the Xuanzhong Ruler was about to fall—

"Ugh……"

A long sigh suddenly echoed in the void.

Xiao Yan and Han Feng were both stunned, and a look of surprise flashed in their eyes at the same time.

"Teacher? You're awake?"

"Master! Feng'er knows she was wrong! Save me!"

In an instant, the ancient ring on Xiao Yan's finger emitted a soft glow, and a semi-transparent white soul phantom slowly emerged.

It was Yao Chen!

Yao Chen's illusory soul slowly emerged, his aged face bearing an indescribable complex expression. He hovered in mid-air, his gaze first falling on Xiao Yan, nodding with satisfaction, before turning to Han Feng, who was kneeling on the ground.

"Master! Feng'er knows he was wrong!" Han Feng cried, tears streaming down his face, kowtowing desperately. "Back then, I was bewitched. I beg you, Master, spare my life! I am willing to repent..."

Yao Chen remained silent for a long time before finally speaking, his voice filled with endless weariness: "Feng'er, do you still remember what the first batch of pills I taught you to refine was back in the Starfall Pavilion?"

Han Feng was taken aback, then said urgently, "It's...it's a Grade One Qi Nourishing Pill! My master taught me how to make it!"

“You’re wrong.” Yao Chen shook his head and sighed, “It’s a Grade One Fire Condensation Pill… You can’t even remember that…”

Han Feng's face turned deathly pale instantly.

Yao Chen slowly raised his illusory palm, a ball of eerie white bone spirit cold fire dancing in his palm, and slowly said, "The biggest mistake I have ever made in my life is that I failed to teach you well. Today, let me personally end this ill-fated relationship."

"No! Master!" Han Feng retreated in terror. "You loved me the most, you said I was your most prized..."

"Shut up!" Yao Chen suddenly shouted, his soul body fluctuating violently. "Do you know how much it has hurt me these past years, every time I think of that poisoned dagger of yours!"

The Bone Spirit Cold Fire transformed into a white longsword, and Yao Chen's voice was terrifyingly calm: "Today, I will settle all of this!"

The moment the longsword pierced Han Feng's chest, an expression of disbelief remained frozen on his face. A blinding white flame instantly spread across his body, but did not immediately incinerate him.

"This sword strike is for your inability to distinguish right from wrong; you are utterly foolish!"

"Oh no……"

Han Feng let out a shrill scream, yet strangely remained conscious.

The second sword strike came in an instant, slashing upwards and severing Han Feng's right arm.

"This sword strike is a tribute to your aiding and abetting evil, and your alliance with the Soul Palace!"

Cold flames flickered from the severed arm, and Han Feng's face twisted like a demon as he let out a heart-wrenching wail.

The third sword strike came down, but suddenly stopped three inches from the center of the forehead.

Yao Chen's hand holding the sword trembled slightly, his voice hoarse: "This sword... I hate that I was blind back then..."

As soon as he finished speaking, the longsword transformed into a rain of fire that engulfed Han Feng completely.

Xiao Yan clearly saw a glint of tears well up in his teacher's eyes the instant Han Feng vanished into thin air. The white-clad figure appeared exceptionally frail in the wind, yet ultimately stood tall and straight.

"Teacher..." Xiao Yan called softly, afraid of disturbing the silence.

Yao Chen turned around, his face a mixture of exhaustion and relief, and reached out to gently stroke Xiao Yan's head: "Good boy, you've had a hard time these past few days."

Upon hearing this, Xiao Yan shook his head and said, "Thanks to Brother Lu's care, I'm quite lucky. I've already fulfilled the three-year agreement and haven't been harassed by the Yunlan Sect..."

"It's just a pity that the teacher didn't see that scene..."

Upon hearing this, Yao Chen nodded with satisfaction. Just as he was about to speak, he suddenly heard a familiar sound of footsteps coming from afar.

"Senior Medicine Master, you're awake?"

A clear voice rang out. A man in a blue robe walked in, bathed in the morning light, a gentle smile on his lips, his clothes fluttering lightly in the breeze. It was Lu Yu.

“Brother Lu!” A hint of joy flashed in Xiao Yan’s eyes.

Yao Chen stared at the young man before him, his illusory figure leaning forward slightly, bowing respectfully, and saying, "My disciple has been fortunate to receive your care during this time."

Lu Yu quickly stepped aside and respectfully returned the greeting, saying, "Senior, you flatter me. Brother Yan is exceptionally talented, and everything he has achieved today is the result of his own hard work. I have only provided a little bit of insignificant help."

A gentle breeze blew by, and the three stood facing each other.

Lu Yu's gaze lingered on Yao Chen's slightly ethereal figure for a moment before he asked gently, "Now that you have awakened, what are your plans?"

Yao Chen stroked his long beard and pondered, "To be honest, my soul power has now recovered to the Spirit Realm, and refining peak seventh-grade pills is no problem for me. Of the three great strange flames, my master and I have obtained two and a half, but we are still missing the Yin Flame from the Yin-Yang Twin Flames, as well as a Dou Zong physical body..."

With a profound gaze, he continued, "After obtaining the Yin Fire, I plan to reshape my physical body, and then take Xiao Yanzi to Zhongzhou to return to the Starfall Pavilion. The resources of the Northwest Continent are ultimately somewhat scarce."

Lu Yu nodded slightly and said, "I can borrow your strange fire for now. As for the Dou Zong body... I already have another use for the Earth Demon Old Ghost's body, but I do have a severed-arm Dou Zong peak corpse. I wonder if you would be interested?"

"Oh?" Yao Chen's eyes lit up, and he asked, "Where did this corpse come from?"

A meaningful smile appeared on Lu Yu's lips: "Heavenly Serpent Palace!"

Upon hearing this, Yao Chen frowned slightly, pondered for a long time, and then slowly shook his head, saying, "The Heavenly Serpent Mansion has a complicated background, and I have not yet recovered my peak strength. This body has a lot of karma, and it is also a body with a missing arm. It would be best to find another way."

As he spoke, Yao Chen suddenly bowed solemnly to Lu Yu, and said in a very sincere tone, "Young friend, you have taken great care of Yan'er, and I have no way to repay you. If you do not mind, I am willing to join the Lingbao Pavilion with my remaining strength and do my bit."

Lu Yu's eyes lit up, and he immediately smiled and said, "It is an honor for Lingbao Pavilion that you are willing to join us, senior. I am naturally happy to welcome you!"

After saying that, Yao Chen rubbed his hands together somewhat awkwardly and said a little embarrassedly, "I have another request... Young friend, may I have a look at the eighth-grade alchemist's inheritance that you gave to Yan'er earlier? I promise that I will only use it for research and will never pass it on to anyone else."

Lu Yu was taken aback at first, then laughed loudly, "Senior, you flatter me. It's truly a blessing that this inheritance has received guidance from the Medicine Venerable."

After saying that, he lightly touched his storage ring with his fingertip, and a jade slip with a lustrous sheen appeared in his palm. He then handed it to Yao Lao.

Yao Chen carefully took the jade slip, and a hint of undisguised joy flashed in his aged eyes.
