The princess arrives and the prosperous Tang Dynasty begins

Li Xuan and Lin Xiao looked at each other, their eyes full of determination. They knew that it was useless to retreat in the face of this powerful demon. The two looked at each other, and they saw determination and perseverance in each other's eyes.

"In that case, let us fight side by side!" Li Xuan said loudly.

Lin Xiao nodded. She knew that this battle might be very difficult, but she would never back down.

"Hmph, two ignorant ants, you actually dare to fight me? Do you think you can defeat me with your insignificant power? How ridiculous!" The devil sneered.

However, Li Xuan and Lin Xiao were not shaken by his words. They held their weapons tightly in their hands, ready to face this life-and-death battle.

Li Xuan took a deep breath and used his best swordsmanship, the Seven Star Swordsmanship. His figure was as erratic as a ghost, and the sword in his hand turned into a series of cold lights, attacking the demon. Each sword contained a powerful force, as if it could tear the air.

Lin Xiao was not to be outdone. She waved the long whip in her hand and used her unique skill - Heavenly Flower Scattering. The long whip danced in the air, turning into countless whip shadows, as beautiful and deadly as the flowers scattered by the heavenly maiden. Each whip shadow carried a powerful force, enough to scare the demon.

The devil sneered disdainfully, and waved his hands violently. A powerful black energy wave swept towards Li Xuan and Lin Xiao like a surging wave. This energy wave exuded a heart-pounding breath, as if it contained a terrifying power to destroy everything, which made people suffocate.

Li Xuan and Lin Xiao's faces changed drastically. They could clearly feel the power and terror of this energy wave. Facing such a terrifying attack, they did not dare to underestimate it.

Almost at the same moment, Li Xuan and Lin Xiao quickly used their best defensive skills. Li Xuan formed seals with his hands, and the powerful spiritual power in his body continued to flow out, forming a transparent shield that tightly wrapped him. Lin Xiao held a sword in her hand, and the sword was shining with dazzling light. She danced with the long sword in her hand, and sharp sword energy whistled out, interweaving into an indestructible line of defense.

At the same time, their eyes became sharp, staring intently at the black energy wave, preparing for the upcoming violent impact.

A golden light appeared around Li Xuan's body, covering him. This was his defensive skill - Diamond Shield. Diamond Shield could resist all attacks, allowing Li Xuan to be invincible in battle.

Lin Xiao waved her long whip, forming a tough defensive wall. This was her defensive skill - Whip Wall. The Whip Wall could block all attacks and keep Lin Xiao safe in the battle.

The black energy wave collided with their defenses, causing a huge explosion. The entire battlefield was shaken by this powerful force, as if the end of the world was coming.

Although the two's defense blocked the demon's attack, they were also shocked by this powerful force and took a few steps back. Li Xuan was secretly surprised. The strength of this demon was indeed strong. They had to be more careful in dealing with it.

The demon didn't give them a chance to breathe. He attacked again, condensing a ball of black flame in his hands and throwing it towards Li Xuan. This ball of flame was so hot that it seemed to turn everything into ashes.

Seeing this, Li Xuan dodged the attack of the flames. The flames fell to the ground, and a sea of ​​fire suddenly ignited. Li Xuan did not dare to neglect it. He used the Seven Star Sword Technique's unique move - Seven Stars in a Row. His figure flashed continuously in the air, and the sword in his hand turned into seven cold lights, attacking the demon.

The demon sneered, a trace of contempt flashed in his eyes, and he gently waved the black sword in his hand, and a black sword energy whistled out, instantly breaking Li Xuan's Seven Stars. Li Xuan was shocked and quickly stepped back, secretly exclaiming in his heart: "This demon's strength is so strong!"

At this time, Lin Xiao took the opportunity to launch an attack. The long whip in her hand was like a flexible snake, dancing in the air, and quickly wrapped around the demon. The long whip flashed a faint light, with a powerful force, as if it could bind everything.

However, the demon was not in a hurry to deal with Lin Xiao's attack. He waved the black sword in his hand, and a black sword energy whistled out again, colliding with Lin Xiao's long whip. With a loud "bang", the long whip was cut into two pieces by the sword energy.

Lin Xiao was shocked. She never expected that the demon was so powerful that her whip could not threaten him. Her face changed and she quickly retracted her whip, preparing to attack again.

When Li Xuan saw Lin Xiao in danger, he immediately rushed forward and started a close combat with the demon. His sword skills were tricky and sharp, and he kept attacking the demon's vital points. The demon was not to be outdone, and he swung his black long sword tightly, dispelling Li Xuan's attacks one by one.

In the fierce battle, Li Xuan and Lin Xiao gradually lost the upper hand. Their physical strength and energy were constantly depleting, while the demon seemed to be getting braver and braver. Li Xuan knew that this was not a solution, and they had to find a way to find the demon's weakness.

At this moment, Li Xuan suddenly found a faint light flashing on the demon's chest. He was moved, could this be the demon's weakness? He immediately told Lin Xiao about this discovery, and the two decided to concentrate their efforts to attack this weakness.

Li Xuan and Lin Xiao both knew that this was a matter of life and death, and they had to go all out. So, they used all their skills and used their most powerful moves. Li Xuan waved his sword, and the sword was shining brightly. He launched the final attack on the demon's chest. Lin Xiao was casting magic on the side, and colorful lights flashed between her fingers, and gorgeous magic flew towards the demon.

The demon felt an unprecedented threat and began to fight back. His eyes turned red and a black smoke came out of his mouth, trying to stop the attack of Li Xuan and Lin Xiao. However, under the joint attack of the two, his defense finally showed a flaw.

Li Xuan seized the opportunity and stabbed the demon in the chest with a sword. The demon screamed miserably and fell backwards. Li Xuan and Lin Xiao took the opportunity to launch the final attack. Their moves fell on the demon like a storm, completely defeating him.

As the demon fell to the ground, the entire battlefield fell into silence. Li Xuan and Lin Xiao stood there, gasping for breath. They successfully defeated this terrible demon and protected world peace. But they also knew that this battle was just the beginning, and there would be more challenges waiting for them in the future.

After the battle, Li Xuan and Lin Xiao both breathed a sigh of relief. They finally defeated this powerful demon, but they also paid a heavy price. Li Xuan's body was covered with wounds, and Lin Xiao's face turned very pale.
