The Wonder of the Emperor Scripture, Bitter Cultivation Underground

"Great Emperor Internal Scripture—isn't this the dual-cultivation method that made the Western Heaven Battle Emperor famous throughout the Great Thousand World?"

Lu Yu raised an eyebrow, looking at the three options in the simulation with some surprise.

As a powerhouse in the top tier beneath the Saint-grade Heavenly Sovereign level in the Great Thousand World, the Western Heaven Battle Emperor had already cultivated his strength to the peak of an Immortal-grade Heavenly Sovereign. He had two cultivation methods renowned throughout the world.

One was called the Great Emperor Internal Scripture, and the other was called the Battle Emperor Art.

The Great Emperor Internal Scripture was the Western Heaven Battle Emperor's one-of-a-kind dual-cultivation method, secretly aligning with the Great Dao of Yin and Yang. Rumor had it that the Battle Emperor's three thousand palace beauties had been the very reason he had risen so rapidly through this method and achieved the Heavenly Sovereign realm.

The Battle Emperor Art, meanwhile, was a unique secret art inherited from the Ancient Battle Emperor. It could merge spiritual energy with battle intent, transforming it into battle spiritual energy, whose power far surpassed ordinary spiritual energy. The Western Heaven Battle Emperor had been able to earn the illustrious reputation of the "Hundred Battles Emperor," and this art could be said to have contributed no small part.

"Among these three options, the Foundation Establishment Chapter of the Great Emperor Internal Scripture is the most precious by far. Although it only contains cultivation methods below the Supreme Stage, its value already far exceeds the other two."

"The Mysterious Water Jade is only a Mid-grade Spirit Artifact. Judging from the simulation, it should have been fused with the spirit essence of a Heaven Melting Stage Spirit Beast. Even if activated at full power, its might would only be comparable to that of a Dou Huang expert."

"As for the Heavenly River Blood Blade, it's an Earth-tier high-grade blood-attribute Dou Technique. Its value is slightly higher than the Mysterious Water Jade, but its attribute doesn't match mine, so it won't be of much use to my cultivation in reality..."

"Besides, Spirit Artifacts and cultivation methods are ultimately easier to obtain. I'll still have a chance to get them in the next simulation. But this Great Emperor Internal Scripture is something that can only be found by luck, not sought..."

At that thought, Lu Yu immediately chose the third option.

In an instant, golden light blazed in the void, and a gilded page appeared out of thin air. The entire quiet chamber was illuminated by that golden page until it shimmered with flowing radiance and color.

Lu Yu held his breath. He saw the golden page densely engraved with ancient runes. Carefully, he reached out to touch it, and the golden page instantly turned into a streak of light that sank into the space between his brows.

In an instant, a vast amount of information exploded in his mind—

"Yin-Yang Harmony, Heaven and Earth in union..."

"Gather the essence of the heavens, absorb the radiance of the moon..."

"Yin and Yang revolve, creation forms of itself..."

The contents of the Great Emperor Internal Scripture flowed through his heart like a clear spring, and the profound essence of dual cultivation within it appeared one by one in his mind.

A moment later, Lu Yu slowly opened his eyes, bright light flowing through his gaze. He thoughtfully touched the space between his brows, inwardly shaken. So that's how it is. This cultivation method actually uses heaven and earth as the cauldron, the sun and moon as fuel, and turns the two dao companions into a spiritual embryo of heaven and earth. By borrowing the mighty power of heaven and earth, it transforms the essence of the sun and moon into Yin-Yang Qi to nourish both sides' foundations...

He focused his mind and comprehended the true meaning of the method. The more he understood it, the more startled he became. The most ingenious part of this art lies in how it can regard the two dual-cultivators as a naturally formed Yin-Yang spiritual embryo. Through the Yin-Yang Qi transformed within the body, it can heal any injury—even if the meridians are completely severed and the dantian damaged, as long as a wisp of Yin-Yang Qi remains, everything can be fully restored!

"Everyone says the Western Heaven Battle Emperor is romantic and unrestrained..."

A gleam flashed through Lu Yu's eyes as he murmured, "But from the looks of it, this man was actually an unparalleled genius who comprehended the Great Dao of Yin and Yang!"

"Using heaven and earth as the furnace and the sun and moon as the firewood, he deduced the dao between man and woman to a heaven-reaching realm. Such methods can no longer be compared to ordinary harvesting techniques. This is clearly the supreme principle of imitating heaven and earth and taking nature as one's teacher!"

Thinking of this, Lu Yu could not help sighing. "As expected, every powerhouse in the Great Thousand World who can become a Heavenly Sovereign is anything but simple. The Western Heaven Battle Emperor was able to reach the Heavenly Sovereign realm through the dao of dual cultivation. Leaving his character aside, at the very least, this level of comprehension is truly admirable..."

Not long after, Somewhere underground in the eastern part of the Tagor Desert.

In the scorching underground world of magma, crimson lava surged like raging waves.

"Bang!"

A scarlet snake shadow was smashed heavily into the rock wall, and the Twin-Headed Fire Spirit Snake let out a pained hiss. Hai Bodong stood in the air, icy-blue Dou Qi circulating around him, freezing the surrounding magma into sheets of Ice Crystal.

"Little girl, now!" Hai Bodong turned his head and shouted.

Qing Lin nodded nervously. After this period of training, she could already use the Jade Serpent Three Flower Eyes proficiently. Though she had not yet reached the level of doing so as effortlessly as she wished, she already had a fair amount of confidence against the Twin-Headed Fire Spirit Snake before her.

She formed seals with both hands, and three small flowers slowly spun within her emerald eyes. A strange energy fluctuation spread outward. "Jade Serpent Three Flower Eyes, open!"

In an instant, the Twin-Headed Fire Spirit Snake's enormous body trembled violently. In all four of its scarlet snake pupils, an emerald three-flower mark was reflected at the same time, emerging as though branded there.

A moment later, When two eerie emerald flowers had fully taken shape on the snake heads, the three small flowers in Qing Lin's eyes receded like the tide. In the blink of an eye, her gaze returned to its usual clear emerald green. Her body swayed, and her face turned as pale as paper. Clearly, she had overexerted herself.

"I... I succeeded..." Qing Lin revealed a weak smile.

Lu Yu was quick-eyed and quick-handed. In a flash, he arrived beside her and took out a warm, jade-like pill from his Storage Ring. "Quick, take this Soul Nurturing Pill!"

He carefully fed the pill into Qing Lin's mouth while circulating his Dou Qi to help her dissolve the medicinal power. Qing Lin's pale complexion gradually regained its color, and the exhaustion between her brows slowly faded as well.

"Thank you, Young Master..." Qing Lin thanked him softly, her eyes filled with gratitude.

Lu Yu instructed her gently, "For now, just rest and recuperate in peace. Focus on establishing a connection with the Fire Spirit Snake. You don't need to worry about anything else."

"Qing Lin understands," the girl answered obediently.

Lu Yu turned to Little Fairy Doctor, who was standing quietly to the side. "Xian'er, I'll have to trouble you to take her back to Stone Desert City first."

The White-clothed Young Girl nodded in understanding, and with a light lift of her fair hand, she naturally hooked her arm around Qing Lin's.

After the two of them left, Lu Yu looked at Hai Bodong and said with a smile, "Old Hai, let's begin."

Hai Bodong's white brows rose slightly. With a light sweep of his sleeve, ice-crystal blades suddenly condensed all across the sky.

"Brat, watch closely!"

Before his words had even fallen, hundreds upon thousands of cold gleams were already tearing through the air toward him.

Whoosh, whoosh, whoosh!

The piercing sound of rushing air echoed through the lava cavern. Lu Yu tapped his toes lightly and retreated in a flash, his figure like a Wandering Dragon, leaving several Afterimages in place. Seeing the ice blades closing in, he suddenly brought his palms together, and a crimson Afterimage erupted with a roar, turning into a ring-shaped shockwave that shattered every incoming ice blade.

"Hmph. In this land of magma, you're actually willing to squander Dou Qi."

Hai Bodong let out a cold snort, though a trace of approval flashed through his eyes. He said in a low voice, "But do you think that's enough to dodge?"

A warning suddenly flared in Lu Yu's heart. Before he could react, the magma beneath his feet abruptly exploded—countless sharp ice spikes had actually burst out in a surprise attack from within the scorching lava!

"What?!"

Lu Yu dodged in haste, but an ice spike still sliced through his sleeve. Icy cold seeped in through the tear, instantly covering his right arm in a thin layer of frost.

Hai Bodong stood with his hands behind his back, his white hair flying in midair. "Kid, this old man won't be holding back!"

With that, his palms flew through the air, forming a profound hand seal. In an instant—

Whoosh, whoosh, whoosh!

Thousands upon thousands of Ice Crystal blades condensed out of thin air, each gleaming with a deep-blue chill as they poured down like a torrential storm.

Rumble!

At the same time, the ground shook violently, and one sharp ice spike after another broke through the boiling magma, launching surprise attacks from impossible angles. As ice and fire intertwined, the entire cavern was shrouded in billowing white mist.

Lu Yu looked at the all-encompassing assault and gave a faint, helpless bitter smile. The days ahead were probably going to be rough...
