The Emperor's Favorite: The Useless and Crazy Concubine Who Conquers the World

Seeing this, Ling Xiuhan immediately understood Lan Yunyan's intention. He shouted loudly, unleashing all his magical power, and joined Lan Yunyan in attacking the runes on the stone gate.

With their joint efforts, the runes on the stone gate gradually shone with dazzling light, and those mysterious people groaned in pain under the light, and finally turned into a wisp of black smoke and dissipated.

As the mysterious man disappeared, the stone gate slowly opened, and a powerful and mysterious force rushed towards them. Lan Yunyan and Ling Xiuhan exchanged a glance and cautiously walked through the stone gate.

Inside the stone gate is a vast cave, its walls inlaid with countless gemstones emitting a strange glow, seemingly telling an ancient and mysterious story. In the center of the cave, there is a stone platform, upon which rests an ancient book emitting a golden glow.

Lan Yunyan slowly walked forward and picked up the ancient book. The words "Secret Book of Holy Power" were engraved on the cover. She gently flipped open the book, revealing the deeper secrets of the source of holy power and its powerful utilisation methods.

Lan Yunyan was overjoyed. She knew that this ancient book would be crucial for them to repair the world and deal with future crises. Just as she was about to study the ancient book carefully, she suddenly heard a noisy sound of footsteps and shouting coming from outside the cave.

Lan Yunyan and Ling Xiuhan hurried out of the cave, only to see a large number of forces from various directions gathered outside the valley. Some of these forces had been bewitched by evil forces, while others had heard of the powerful power of the Source of Holy Power and coveted it, hoping to seize it.

Leading the group was a man in golden armor, his eyes gleaming with arrogance and greed. "Lan Yunyan, hand over the source of holy power and that ancient book, or today will be your day of death!" the man shouted.

Lan Yunyan snorted coldly: "You greedy people, the source of holy power is used to protect the heaven and earth, how can you rob it!"

With that, Lan Yunyan increased the power of her Holy Energy to its maximum. Her Chaos Divine Axe and golden spear hummed, ready for the coming battle. Ling Xiuhan also stood beside her, the black sword energy emanating from his demonic sword surging wildly as he fought alongside Lan Yunyan.

The battle was about to break out, and the valley was plunged into chaos. Lan Yunyan, relying on the source of holy power and the new techniques learned from ancient texts, repeatedly repelled the enemy's attacks. Each of her attacks was like a mountain falling down, carrying a powerful surge of holy power that made it difficult for the enemy to resist.

Ling Xiu Han skillfully cooperated with Lan Yunyan. His magic sword was like a ghost, moving freely among the enemy groups, looking for the enemy's flaws and delivering a fatal blow.

However, the enemies were numerous and seemed to be well prepared, constantly casting all kinds of strange spells and weapons, causing considerable trouble to Lan Yunyan and Ling Xiu Han.

In the fierce battle, Lan Yunyan suddenly realized that although the enemy's attacks seemed chaotic, they actually had a common goal: to weaken her connection with the source of holy power. She was shocked, realizing that there might be a more powerful force behind these enemies, controlling everything.

Lan Yunyan decided to change her tactics. She no longer relied solely on the powerful force of the source of holy power to attack, but instead used the techniques recorded in ancient books to more cleverly combine the holy power and the power of nature to form a more concealed and powerful force.

She flashed, weaving through the enemies like a bolt of lightning, the Chaos Axe and golden spear in her hands dancing with impenetrable force. Each attack contained the dual might of holy power and natural force, leaving the enemy defenseless.

Ling Xiu Han also felt the change in Lan Yunyan. He immediately adjusted his attack method and echoed with Lan Yunyan, forming a powerful combat tacit understanding.

Gradually, the enemy's attacks began to become chaotic. They were unable to withstand the powerful offensive of Lan Yunyan and Ling Xiuhan and began to retreat.

But the man in golden armor refused to accept defeat. He suddenly produced a black bead and muttered something. As he chanted, the bead emanated a powerful dark force that enveloped the surrounding enemies, instantly increasing their strength.

Lan Yunyan saw this and thought to herself, "This is not good." She knew that the bead in this man's hand must be an evil and powerful magic weapon. If it wasn't destroyed quickly, the battle would become even more difficult.

Lan Yunyan then concentrated all her energy, mobilizing the full force of her holy power, converging it upon the Chaos Divine Axe. The axe suddenly shone with a dazzling multicolored light, imbued with the power to annihilate heaven and earth.

"Ling Xiu Han, cover me!" Lan Yunyan shouted, then rushed towards the man.

Ling Xiuhan responded, unleashing all his magical power to clear a path for Lan Yunyan. Under Ling Xiuhan's protection, Lan Yunyan quickly approached the man, then raised the Chaos Divine Axe high and chopped down the bead in the man's hand.

Seeing this, the man's face changed drastically. He tried his best to resist Lan Yunyan's attack, but under the powerful power of the source of holy power, his resistance seemed insignificant.

With a resounding bang, the Chaos Axe struck the bead fiercely. The bead instantly screamed before dissipating in a puff of black smoke. The man, struck by the bead's shattering blow, vomited blood and collapsed to the ground.

As the man fell, the other enemies suddenly lost their backbone and fled in all directions.

Lan Yunyan and Ling Xiu Han did not pursue these enemies. They knew that this battle was just the beginning and there might be more challenges waiting for them in the future.

Lan Yunyan and Ling Xiuhan returned to their camp with the Holy Power Secret Book. In the days that followed, Lan Yunyan began to study the Holy Power Secret Book intently, exploring its deeper mysteries in order to better utilize the power of the Holy Power Source.

Ling Xiu Han silently guarded her and constantly improved his own strength to prepare for possible crises in the future.

Thanks to their efforts, the restoration work in the Divine Realm and the Land of Chaos is progressing more and more smoothly.
