Choice, Sky Burning Sea Boiling Palm!

The scene inside the Library Pavilion suddenly changed.

Lu Yu's view opened up, and a magnificent circular hall appeared before his eyes. On the surrounding walls, more than a dozen energy barriers flickered on and off like breathing, illuminating the entire space as bright as day.

Suddenly, dense sounds of rushing wind rang out from every direction. Countless multicolored energy clusters shot in like meteors, weaving through the hall and bringing up waves of whistling.

These light clusters came in all shapes. Some were like Wandering Dragons, others like starlight, and each one radiated a unique energy fluctuation.

Lu Yu's gaze sharpened. His right hand shot out like lightning and precisely caught a ball of pale-red light. As the glow faded, a crystalline, fiery-red crystal appeared in his palm.

Inside the crystal, gilded liquid flowed slowly, flickering with a strange luster as though it were alive.

"This is... Earth Core Flame Marrow?"

A hint of surprise flashed through Lu Yu's eyes. This object was condensed from the essence of magma deep within the earth and was greatly beneficial to fire-attribute cultivators. What surprised him even more was that this piece of Earth Core Flame Marrow had formed a subtle resonance with his Earth Core Flame.

"Looks like it was drawn over by the Earth Core Flame..."

Joy flashed through Lu Yu's eyes. To gain such a harvest the moment he entered the Library Pavilion was truly beyond his expectations.

This piece of Earth Core Flame Marrow was of excellent quality. If the Earth Core Flame could absorb it, even if it could not make the Strange Fire evolve, it would certainly greatly increase its power.

"But I should look at the other treasures first."

Now that he had advanced to Dou Ling, the Profound-tier Dou Skills he had practiced in the past were gradually falling behind. It was time to search for higher-level Earth-tier Dou Skills.

"It would be best to find an Earth-tier palm-type Dou Skill. With my experience cultivating Guardian Trigram Palm before, I should pick it up faster..."

Thinking this, he temporarily put the flame marrow aside and looked around.

He saw everyone turning into Afterimages, darting back and forth through the spacious room as they fought to catch the light clusters shooting out from the energy barriers.

"Sky Jade Fruit!"

A blue-robed man suddenly cried out in surprise, holding a medicinal plant that was entirely like jade. At the top of the plant was a jade-like fruit.

It was indeed a Sky Jade Fruit. Simply consuming it directly could raise one's Dou Qi strength by around one star, and if it were used to refine a pill, as long as the pill formed, it would definitely be a pill capable of directly increasing the strength of a Dou Wang expert.

After catching this medicinal herb, the man did not hesitate at all and swallowed it in one bite. Meanwhile, the man and woman traveling with him watched Lu Yu and Little Fairy Doctor warily.

Lu Yu shook his head with a laugh, then looked toward Little Fairy Doctor. He saw that she was chasing a purple light cluster the size of a human head. Though her movement technique was fast, she still could not touch it.

"I'll do it!"

The Purple Cloud Wings on Lu Yu's back abruptly unfolded, and he turned into a streak of crimson light as he chased after it. However, the instant his fingers touched the light cluster, a powerful repulsive force erupted and forcibly knocked him back. The purple light cluster took the chance to break free and plunged back into an energy barrier.

"Interesting..."

Lu Yu landed beside Little Fairy Doctor and asked with a smile, "You really want that one?"

Little Fairy Doctor nodded and said, "I vaguely saw just now that it was a movement-type Dou Skill scroll. It suits me perfectly."

"Then leave it to me!"

A sharp gleam flashed in Lu Yu's eyes. He joined two fingers like a sword, and a blue-red Fire Thread tore through the air, shooting straight at that purple energy barrier!

Bang!

The energy barrier exploded on impact. Countless purple Light Points scattered like stars, and a scroll that looked entirely like purple jade slowly emerged. Fine lightning patterns flowed across its surface, giving off energy fluctuations that made one's heart tremble.

Lu Yu clenched his hand in the air, and a gentle suction force drew the scroll over. The moment the scroll entered his hand, he clearly felt a numbing current spread along his arm.

Looking down, he saw five ancient, vigorous characters on the scroll—"Purple Thunder Jade Illusory Body." Each stroke seemed to have been condensed from thunder, and tiny electric snakes could faintly be seen swimming within them.

"It's actually an Earth-tier low-grade movement Dou Skill, and a rare lightning-attribute one at that..."

A trace of astonishment flashed through Lu Yu's eyes. One had to know that the lightning attribute was already known for speed, and when paired with such a high-level movement Dou Skill, it was simply adding wings to a tiger.

Without any hesitation, he handed the scroll to the purple-clothed Young Girl beside him. "This Dou Skill suits you perfectly."

A soft smile appeared in Little Fairy Doctor's eyes. With a gentle lift of her fair hand, the purple scroll entered her Storage Ring. She turned to look at Lu Yu and asked softly, "What about you? Have you found a treasure you like?"

Lu Yu shook his head and said, "Not yet. I originally planned to choose an Earth-tier fire-attribute palm technique, but I haven't found one so far..."

He quietly calculated in his heart: among the Earth-tier offensive Dou Skills he currently possessed, the Heavenly Dragon Flame Finger was indeed powerful, but in the end, it was only Earth-tier low-grade. As for the Emperor Seal Art, although it was Earth-tier high-grade, its consumption was too great for him right now, making it difficult to use as a regular method.

"It would be best to find an Earth-tier mid-grade Dou Skill..."

Lu Yu's gaze swept over the flying light clusters around him as he thought to himself, "It could make up for my lack of offensive methods without consuming too much Dou Qi."

Just then, he suddenly sensed something and raised his head to look toward the depths of the Library Pavilion.

A streak of red-gold light cut across the air. Wherever it passed, space twisted and heat waves rolled.

"What astonishing fire-attribute energy!"

A sharp light surged in Lu Yu's eyes. His figure instantly turned into a crimson Afterimage and pursued it. That red-gold light cluster seemed to possess intelligence, and its speed abruptly increased, drawing a brilliant Fire Thread through the air.

"Trying to run?"

Lu Yu snorted coldly and flicked all ten fingers in succession. Dozens of blue-red Fire Threads tore through the air and wove into an airtight fire net, surrounding the red-gold light cluster from all sides.

Hiss, hiss!

The instant the fire net touched the light cluster, dazzling light erupted. Lu Yu seized the opportunity, thrusting out his right palm as the Earth Core Flame surged forth, transforming into a giant flaming hand about ten feet large that grabbed fiercely at the light cluster.

"Crack!"

With a crisp shattering sound, the energy barrier on the surface of the red-gold light cluster finally collapsed.

A scroll that seemed cast entirely from crimson gold slowly emerged, blazing runes flickering over its surface. The five ancient words "Sky Burning Sea Boiling Palm" could be vaguely seen shining brilliantly.

Lu Yu held the scroll, swept it with his Soul power, and delight immediately appeared on his face.

Sky Burning Sea Boiling Palm, also known as Crimson Gold Nine Revolutions Sky Burning Palm, was an Earth-tier mid-grade fire-attribute Dou Technique.

The palm technique was divided into nine revolutions, and each revolution could stack one layer of "Crimson Gold Flame Force." When all nine revolutions reached perfection, the force of the palm would be like nine great suns layered together, burning mountains and boiling seas, destroying cities and splitting the earth.

It was said to be the ultimate sect-guarding art of the Crimson Gold Sect from ancient times. This palm technique was incomparably fierce and powerful; cultivated to great mastery, it was enough to rival ordinary Earth-tier high-grade Dou Techniques!

"Good!"

Joy rose in Lu Yu's heart. This palm technique suited him perfectly. If it had been an ordinary Earth-tier low-grade Dou Technique, he might have chosen the Earth Core Flame Marrow instead.

But this palm technique was clearly of somewhat higher value. Not only did it suit his current needs, even if he used it later as a Dou Zun, it would not be considered outdated. It could be said to be extremely fitting.

Just as Lu Yu was immersed in the joy of his gains, an aged voice suddenly rang out inside the Library Pavilion.

"Time is up!"

The voices of the Thousand Hundred Elders echoed through the space.

"All students, leave the Library Pavilion at once!"

Lu Yu quickly put the scroll into his Storage Ring, then turned to look at Little Fairy Doctor. The two nodded, then walked toward the exit passage together with the other three students.

When they passed through the spatial portal and returned to the valley, Vice Principal Hu Gan had already been waiting for some time. Seeing the unconcealable delight on the five of their faces, the white-haired old man stroked his beard and smiled.

"Looks like all of you gained quite a lot."
