Chapter 273 A Four-Star Dou Sheng Sets Off for the Ancient Clan!
Half a month later,

South of Dragon Island, the sky above Tianlong Abyss suddenly darkened. Dark clouds gathered from all directions, condensing into thick thunderclouds at the top of the abyss.

Suddenly, a golden beam of light burst through the clouds from the bottom of the abyss. Within the beam, a pill the size of a longan slowly rose, its surface shimmering with golden light and emitting a chilling energy fluctuation.

Ninth-grade Mystic Pill, complete!

Just as the pills were taking shape, a rich medicinal fragrance suddenly rose up. The fragrance seemed to have a spirit, condensing and sublimating in the air, forming thumb-sized pill beads that fell from the sky.

These are no ordinary pill beads, but rather a rain of pills formed from the condensed essence of elixirs. Each one contains pure medicinal power, and when it falls on various parts of Dragon Island, the vegetation grows at a visible speed, and the spiritual herbs bloom with extraordinary brilliance.

However, this was only the beginning. After the rain of cinnabar, the dark clouds at the top of the abyss suddenly surged, and lightning bolts darted wildly within the rolling thunderclouds, exuding an aura of world-destroying destruction—the cinnabar lightning had descended!
Lu Yu stood with his hands behind his back at the bottom of the abyss, calmly gazing at the Xuan Dan in the air.

Based on my previous experience in refining pills, the appearance of the pill rain means that the Dragon and Phoenix Supreme Pill has been successfully condensed. The next step is to see if it can withstand the baptism of pill lightning.

He could sense that the dragon and phoenix power contained in this ninth-grade Xuan Dan was actually inferior to the Dragon and Phoenix Supreme Pill that he had refined for Zi Yan last time.

Even so, they should be more than capable of surviving this Danlei.

“Go,” Lu Yu murmured to himself, “let me see just how far you can grow.”

The first bolt of lightning crashed down, its blinding light illuminating the entire sky as if it were daytime. The elixir trembled violently amidst the lightning, its surface shimmering with golden light, and it actually absorbed the entire bolt of lightning.

Immediately afterwards, the second and third bolts of lightning struck down in succession, each more ferocious than the last. The Xuan Dan floated in the sea of ​​lightning, its golden light growing ever brighter, with faint phantom images of dragons and phoenixes swirling within it.

As the ninth bolt of lightning dissipated, the golden light on the surface of the Xuan Dan had solidified into a tangible substance. Just then, it suddenly transformed into a stream of light, about to break through the sky into the distance.

"Want to go?"

Lu Yu chuckled lightly, and as if prepared, he raised his hand and made a grasping motion. An invisible force instantly enveloped the heavens and earth, and the Xuan Dan, which was about to escape, was immediately suspended in mid-air, unable to break free no matter how hard it struggled.

"After going through so much trouble, how can we let you get away like this?"

Just as he was about to put the Xuan Dan into the jade bottle, the entire Dragon Island suddenly trembled slightly.

The energy above Tianlong Abyss fluctuated violently, causing the energy of heaven and earth within a radius of a thousand miles to become disordered. This commotion obviously alarmed the powerful figures on Dragon Island. A purple streak of light rushed from the direction of the Dragon Emperor's Palace and landed at the edge of the abyss in the blink of an eye.

"What a strong energy wave!"

Zi Yan landed gracefully, her purple-gold skirt fluttering in the aftershocks of the energy. She first looked around warily, but when she saw the still-struggling Xuan Dan in Lu Yu's hand, her beautiful eyes flashed with surprise: "A ninth-grade Xuan Dan? It was successfully refined?"

Lu Yu nodded with a smile: "It's finally done. Zi Yan, I need to refine this pill here, and I cannot be disturbed in any way. I'll trouble you to protect me during this time."

Zi Yan's expression turned serious, and a powerful dragon and phoenix aura flowed around her. A purple-gold light screen instantly enveloped the entire Heavenly Dragon Abyss: "Don't worry, with me here, I will never let anyone get close."

Lu Yu said no more and immediately sat down cross-legged. He took a deep breath and put the Xuan Dan into his mouth. The moment the pill entered his body, a vast amount of energy erupted within him like a bursting dam, and his entire body was instantly enveloped in dazzling golden light.

He activated the Great Floating Pagoda Technique, and the Floating Pagoda within his body, which had been upgraded to a mid-grade divine artifact, immediately emitted a deep hum. The pagoda's body radiated brilliant divine light and began to slowly rotate within his dantian.

The pure medicinal power transformed from the Xuan Dan after entering the body is now being extracted and refined bit by bit by the Floating Pagoda. Golden Floating Pagoda Flame rises from the surface of the pagoda, gently enveloping this medicinal power and beginning its initial tempering.

As the first wisp of medicinal power was successfully converted, Lu Yu's cultivation level fluctuated significantly. His previously stable mid-stage three-star Dou Sheng realm began to loosen, and the Dou Qi in his meridians became increasingly abundant.

"boom!"

A soft thud resounded from within his body, and the barrier of a late-stage three-star Dou Sheng shattered. After the breakthrough, the refining speed of the Floating Pagoda significantly increased, and the medicinal power was transformed into pure Dou Qi like a tidal wave, propelling his cultivation to continue its ascent.

When his cultivation reached the peak of a three-star Dou Sheng, the rotation speed of the Floating Pagoda had reached its limit. All the ancient runes on the pagoda's surface lit up, and the temperature of the Floating Pagoda Fire rose to its peak. Under such efficient refining, the remaining medicinal power finally broke through that crucial barrier—

Four-star Fighting Saint!

Even after its breakthrough, the pagoda did not stop, tirelessly refining the last remaining medicinal power. Only when all the energy was completely absorbed did the pagoda slowly cease rotating, and its divine light gradually receded.

At the same time, Lu Yu slowly opened his eyes, a sharp glint in them. He carefully sensed the changes within his body, a knowing smile appearing on his lips.

"Peak of a four-star Dou Sheng..."

While the result was not as expected, it was still within reason. After all, this was the second time he had taken the Dragon-Phoenix Supreme Pill, and the effect of drug resistance could not be ignored. However, even so, breaking through to the peak of the four-star Dou Sheng in one fell swoop was still a considerable achievement.

He got up and stretched, feeling the power several times stronger than before flowing through his body. Although he hadn't reached the level of a five-star Dou Sheng like Zi Yan, with his current strength, if he were to fight Huang Tian again, he certainly wouldn't be as strained as before.

"Brother Lu Yu, how are you feeling?"

Zi Yan removed the barrier and quickly walked to his side, examining his condition with concern. When she sensed the significantly stronger aura emanating from Lu Yu, her eyes immediately lit up with joy: "It seems the refining process was quite effective this time."

Lu Yu smiled slightly, and a ball of pure battle qi condensed in his palm: "Peak of the four-star Dou Sheng. Although you didn't reach the five-star level, this result is still quite good."

He looked into the distance, his eyes filled with anticipation: "With my current strength, even without the help of the formation, if I were to encounter an opponent like Huang Tian again, I should be able to truly confront him head-on."

As he spoke, he looked at Zi Yan: "I'm preparing to return to Lingbao Pavilion; it's time to head to the ancient clan." "I want to go too!" Zi Yan immediately took his arm, her eyes filled with anticipation.

Lu Yu smiled helplessly and nodded, saying, "That's possible, but we need to inform Elder Qingshan first. After all, you are now the Dragon Emperor, and you can't just leave Dragon Island without a word."

"OK,"

Zi Yan blinked and revealed a sly smile, "Then let's go find Elder Qingshan. Anyway, with the elders in charge of Dragon Island's affairs, there won't be any trouble for the time being."

As she spoke, she pulled Lu Yu toward the Dragon Emperor's Palace, clearly eager to set off.

……

Soon after,

Inside the Dragon Island Hall,

After hearing the purpose of their visit, Elder Qingshan stroked his long beard and pondered for a moment before finally sighing helplessly, "Since Your Majesty has made up your mind, this old minister will not offer any further advice. However..."

He turned to Lu Yu, solemnly cupped his hands in a salute, and said with a hint of earnestness in his voice, "I hope that Pavilion Master Lu will take good care of His Majesty the Dragon Emperor during this trip. Although His Majesty is quite powerful, he is still young and lacks experience in dealing with people. Moreover, the ancient clans are the top powers of the human race, and they have many rules and regulations..."

"Don't worry, Elder," Lu Yu replied with a smile, glancing gently at Zi Yan beside him. "With me here, I will never let Zi Yan suffer the slightest grievance. Besides, with her current strength, there aren't many people who can make her suffer."

Zi Yan pouted unhappily from the side: "I am not a child anymore, Elder, you are worrying too much."

Elder Qingshan continued his earnest admonitions, his aged eyes filled with concern: "Your Majesty, remember to temper your temper and avoid conflicts with others. If you encounter any trouble, remember to send a message back to Dragon Island immediately..."

"I know, I know!"

Zi Yan waved her hands repeatedly, eagerly pulling Lu Yu out, "Don't worry, Elder, we'll be right back!"

Watching the two figures disappear into the distance, Elder Qingshan shook his head and smiled wryly, yet his eyes held a hint of relief. He murmured to himself, "With Pavilion Master Lu by my side, there's not much to worry about. It's just that Dragon Island will probably be quiet for a while longer..."

……

After a few days,

Before the Lingbao Pavilion on Tianmu Mountain, several figures already stood solemnly on the bluestone plaza. Led by Venerable Tianhuo, the group immediately bowed respectfully upon seeing the familiar figure in the sky, their voices echoing across the misty mountain peak:
"Welcome back, Pavilion Master!"

Lu Yu and Zi Yan landed gracefully, waving their hands gently: "No need for formalities, everyone can disperse."

After everyone stood up, he looked at the white-haired and white-bearded Venerable Tianhuo and casually asked, "How have things been in the pavilion these days? Where are Xian'er and Cailin?"

Venerable Tianhuo hurriedly reported, "Everything is fine in the pavilion. Little Fairy Doctor emerged from seclusion the day before yesterday and is currently playing chess with Miss Cailin in the pavilion on the mountaintop."

Upon hearing this, Lu Yu smiled slightly, exchanged a glance with Zi Yan, and the two walked towards the exquisite pavilion at the top of the mountain.

Walking along the winding stone path, you can see two familiar figures sitting opposite each other in the pavilion.

The Little Fairy Doctor, dressed in snow-white robes, held a chess piece in deep thought with her slender fingers; Cai Lin, in a seven-colored dress, lightly tapped the edge of the chessboard with her fingertips. The aroma of tea wafted from the stone table, creating a scene of leisurely chess playing.

"It seems they've been having a good time while we were away," Lu Yu chuckled.

Zi Yan's eyes lit up, and she was about to greet him when Lu Yu gently stopped her. He lowered his voice and asked, "You know what to say later, right?"

"I know, I know," Zi Yan winked knowingly, a sly smile playing on her lips. "Leave it to me."

After saying that, she strode towards the pavilion and called out loudly, "Sister Xian'er, Sister Cailin!"

When the two girls looked up, she straightened her back and said with a hint of excitement, "I have something to tell you—Lu Yu and I are together now!"

Upon hearing this, Lu Yu swayed and nearly lost his balance. He had thought Zi Yan would be more tactful, but he hadn't expected her to be so blunt.

With a soft "tap," the white chess piece between Little Fairy Doctor's fingers landed on the chessboard. She paused slightly, then smiled gently: "Oh? That is... something to celebrate."

Cai Lin slowly set down her teacup, her phoenix eyes narrowing slightly as her gaze swept between the two of them. A half-smile played on her lips: "No wonder you haven't been seen all this time..."

Just as Lu Yu was about to explain, Zi Yan grabbed his arm first and said matter-of-factly, "You'll have to tell me sooner or later anyway, so there's no point in hiding it!"

Feeling the gentle yet inquisitive gaze of Little Fairy Doctor, and the ambiguous smile on Cai Lin's face, Lu Yu immediately regretted his actions.
"Zi Yan, you're trying to get me killed!"

He looked helplessly at Zi Yan beside him, who had a completely calm expression. This girl had no idea how many follow-up questions her casual remark would elicit.

Cai Lin elegantly picked up her teacup and took a sip, a hint of amusement flashing in her phoenix eyes: "It seems... some people need a proper explanation."

The Little Fairy Doctor gently arranged the chess pieces on the board and softly replied, "Yes, we all really want to know what exactly happened during this time."
