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

In the days that followed, Lan Yunyan studied the Secret Codex of Holy Power day and night, constantly trying to fuse holy power with various natural forces, creating many powerful spells. Ling Xiuhan, on the other hand, devoted himself to practicing magic, improving his magic power and swordsmanship.

Around the camp, they deployed Five Elements Holy Power shields according to the records in the Secret Book of Holy Power to strengthen the defense. At the same time, they also sent out some spies to closely monitor the movements of various forces to prevent the enemy from attacking again.

However, the peaceful days did not last long. One day, Lan Yunyan was practicing in the tent when she suddenly felt a strong fluctuation of holy energy coming from afar.

Her expression changed, "Oh no, I'm afraid there's something wrong with the source of holy power!"

Ling Xiuhan also noticed something unusual, "Let's go check it out!"

The two of them immediately stood up and flew towards the direction of the holy power fluctuations. Along the way, they saw a strange aura in the sky, as if some evil power was awakening.

When they arrived at the valley where the source of holy power was located, they were shocked by the scene before them. They saw a group of mysterious men in black gathered around the source of holy power, holding strange magical instruments in their hands, trying to seal the source of holy power.

"Stop!" Lan Yunyan shouted, and swung the Chaos Axe in her hand towards the man in black.

Seeing this, the men in black turned and attacked Lan Yunyan and Ling Xiuhan. These men were extremely powerful, and their magic was strange. Lan Yunyan and Ling Xiuhan were temporarily caught in a difficult battle.

Lan Yunyan was extremely anxious. She knew that if the source of the holy power was sealed, it would bring great disaster to the world. She rushed towards the source of the holy power desperately, trying to stop the black-clad man's actions.

Ling Xiu Han was struggling to fend off the attacks of the men in black from behind, buying time for Lan Yunyan.

"Yunyan, be careful!" he shouted.

Lan Yunyan came to the source of holy power and found that these men in black had set up a powerful sealing formation around the source of holy power.

She tried to use her holy power to break the formation, but found that her holy power was absorbed by the formation, which instead strengthened the power of the seal.

"What should I do?" Lan Yunyan was extremely anxious.

At this moment, she suddenly remembered a method of breaking the seal mentioned in the "Secret Book of Holy Power" - using blood as a guide to stimulate the original power of the source of holy power.

Lan Yunyan didn't hesitate at all. She picked up the Chaos Axe, cut her palm, and dripped blood onto the source of holy power.

As the blood dripped, the source of holy power emitted a strong light, which contained the power to destroy heaven and earth. The primordial power of the source of holy power was stimulated and instantly broke through the seal of the man in black.

Seeing this, the men in black's faces changed drastically, and they fled in all directions. Lan Yunyan and Ling Xiuhan did not pursue them. Instead, they sat on the ground exhausted, gazing at the newly freed source of holy power with a sigh of relief.

"It was really dangerous this time." Ling Xiu Han said.

Lan Yunyan nodded in agreement. "Well, we must find a safer way to protect the source of holy power as soon as possible. We can't let it fall into the hands of the enemy."

After returning to the camp, Lan Yunyan began to research a new method of sealing the holy power based on the records in the Secret Book of Holy Power. This method of sealing could not only protect the source of the holy power, but also conceal its aura, making it difficult for the enemy to find it.

After several days and nights of hard work, Lan Yunyan finally succeeded in creating a new method to seal the holy power. She and Ling Xiuhan sealed the source of the holy power and hid it in a secret place.

However, they knew this was only temporary peace. In this vast world, danger still lurked in the shadows. The secret of the source of holy power had been revealed, and perhaps even more powerful enemies would come to seize it in the future.

To improve their strength, Lan Yunyan and Ling Xiuhan decided to leave the camp and go to the depths of the Chaos Land to practice. There are all kinds of mysterious powers and dangers, but also countless opportunities and challenges.

Deep in the land of chaos, they encountered various powerful monsters and mysterious ruins.

Relying on the wisdom in the "Secret Book of Holy Power" and her own courage, Lan Yunyan continuously broke through herself and mastered the more powerful methods of using holy power.

Ling Xiu Han also improved his magic power and swordsmanship in battles with various dangers. His magic sword became sharper and his sword energy became more powerful.

One day, while exploring an ancient ruin, they discovered a mysterious magic weapon - the Heart of Chaos.

This magic weapon contains the core power of the Chaos Land, can enhance the strength of the user, and has a certain inhibitory effect on the source of holy power.

Lan Yunyan and Ling Xiuhan looked at each other, both with surprise in their eyes.

"This Heart of Chaos may be the key to our protection of the source of holy power." Lan Yunyan said.

Ling Xiu Han nodded in agreement, "Yes, but it might not be easy to control it. We have to proceed with caution."

They cautiously approached the Chaos Heart, attempting to subdue it. However, a powerful barrier surrounded it, triggering a powerful attack upon contact. Lan Yunyan and Ling Xiuhan attempted multiple times, but were each repelled by the barrier's power, sustaining severe injuries.

"We can't go on like this. We have to think of another way." Ling Xiu Han said with a frown.

Lan Yunyan looked at the Heart of Chaos and suddenly had an idea.

"I remember the Secret Book of Holy Power mentioned a method to break the ban. Maybe we can give it a try."

She closed her eyes, recalled the records in the book, then mobilized the power of the source of holy power and attacked the restrictions around the Heart of Chaos.

This time, her attack was no longer a blind charge, but she skillfully used her holy power to look for flaws in the restriction.

Thanks to Lan Yunyan's efforts, the restriction finally began to loosen slightly. Seeing this, Ling Xiuhan immediately unleashed the power of his magic sword, cooperating with Lan Yunyan to attack the restriction. After much hard work, they finally succeeded in breaking the restriction and subduing the Heart of Chaos.

With the help of the Heart of Chaos, Lan Yunyan and Ling Xiuhan's strength increased greatly.
