After Lin Tian became the guardian of the cultivation realm, he embarked on a journey full of challenges and adventures. He knew that he needed to continue to cultivate and improve his strength in order to better protect the peace of the cultivation realm.

Lin Tian came to a place called "Heavenly Demon Mountain" in the cultivation realm, which was one of the most dangerous places in the cultivation realm. Legend has it that there is a powerful demon beast sealed in the Heavenly Demon Mountain, and it has the power to destroy everything. Lin Tian decided to challenge this demon beast as a way to test his strength.

After entering the Heavenly Demon Mountain, Lin Tian felt a strong evil aura, and darkness and terror filled the surroundings. He walked cautiously, always on his toes. Suddenly, a huge demon beast appeared in front of him, with a hideous face and sharp claws, emitting a foul smell.

Lin Tian stood at the foot of the Heavenly Demon Mountain, looking up at the towering peaks, his heart full of determination and expectation. He knew that this challenge would be an important test on his path to cultivation, and it would also be an opportunity for him to break through himself.

He embarked on a steep mountain path to the top of the mountain, which was full of dangers and challenges. The mountain road is rugged, sometimes there are cliffs, sometimes there are sinister poisonous insects, snakes and beasts. However, Lin Tian did not flinch, he relied on his cultivation and courage to move forward step by step.

Finally, he reached the top of the mountain. In front of you is a vast plain, and in the center stands a huge stone monument. The stele is engraved with two large characters: "Heavenly Demon". Lin Tian's heart was shocked, he knew that the demon beast was in this plain.

He cautiously walked into the plain, silent except for the sound of the breeze. Suddenly, a gust of wind blew, and the sky was covered with dark clouds, as if to foretell the impending danger.

"Invincible, come out!" Lin Tian shouted loudly, his voice echoing through the plains, as if stirring up some kind of power.

As the mountains shook for a while, the ground in the middle of the plain began to crack, and a huge demon beast rushed out of the ground. It was tall, with black and red skin and a fierce glint in its eyes. This is the legendary invincibility, with the power to destroy everything.

Lin Tian clenched the sword in his hand tightly, ready to start a life-and-death struggle with the demon beast. He took a deep breath, his whole body's strength focused on his sword, ready to strike a blow. However, just as he was about to make a move, the demon beast suddenly let out a deafening roar, and the entire valley trembled.

Lin Tian was stunned by the roar, but the demon beast in front of him suddenly disappeared. He looked around and found himself in a completely different scene. It was a barren land, the sky was grey, and the ground was full of cracks and bones. He felt an even stronger aura of evil, as if the whole world was shrouded in darkness.

Lin Tian's heart moved, and he realized that he had entered the territory of the demon beast. The place was full of endless horrors and dangers, and he had to move forward cautiously and be vigilant at all times.

He continued to walk forward, the ground beneath his feet becoming more and more unstable, and every now and then huge cracks appeared. He carefully jumped over the cracks, fearing that he would fall into them if he was not careful.

Suddenly, a gust of wind blew, and Lin Tian felt that something was quietly approaching him. He immediately became alert and looked around, but saw nothing. His heart raced, and he knew he had fallen into the trap of the demon beast.

At this moment, a huge claw suddenly stretched out from the ground and attacked Lin Tian. Lin Tian reacted quickly and dodged, while swinging his sword and slashing at the claws. However, his sword only slashed across the surface of the claw, causing no damage.

The figure of the demon beast was gradually revealed, with its hideous face and sharp teeth, exuding a foul smell. This is the legendary invincible monster, which has great strength and ferocious attack ability.

Lin Tian's heart was cold, he knew that he was facing an extremely difficult battle. He must find the monster's weakness as soon as possible to have a chance to defeat it.

He thought quickly, and suddenly came up with a solution. He decided to use the monster's attack power to lead it into a more favorable arena for himself.

Lin Tian quickly retreated, and the demon beast chased after him. He found a narrow valley and decided to start a final duel with the monsters here.

Lin Tianxin stood at the top of the mountain, staring at the vast plain in front of him, his heart full of tension and excitement. He knew that the invincible demon beast was in this plain, and his mission was to destroy this demon and protect the safety of humans.

Lin Tianxin is a young and brave hunter who has been determined to be a great warrior since he was a child, protecting people from monsters. After years of cultivation and fighting, he finally had the opportunity to face the invincible demon beasts, which was his dream all along.

He took a deep breath and stepped firmly onto the plain. The plain is rich in vegetation and the fragrance of flowers and plants, but none of this can hide the huge stone monument in the center of the plain. Lin Tianxin approached the stone tablet and carefully observed the two big characters engraved on it: "Heavenly Demon".

These two words seemed to carry a mysterious power, which shocked Lin Tianxin's heart. He knew that this demon beast was invincible, and it was an existence known as a heavenly demon, and it had incomparably terrifying strength. It is said that its power can destroy the entire world and plunge humanity into eternal darkness.

Lin Tianxin was determined to destroy this demon and bring peace and tranquility to mankind. He began to search around the plains, looking for traces of invincibility. Minutes and seconds passed, but he never found any clues.

Just as he was about to give up, a low roar suddenly sounded. Lin Tianxin immediately became alert, he quickly turned around and ran in the direction where the voice came from.

Soon after, he came to a huge cave. The cave was dark and eerie, with a suffocating stench. Lin Tianxin walked into the cave without hesitation, ready to face the invincible demon beast.

The interior of the cave was unusually spacious, and Lin Tianxin walked cautiously. Suddenly, he heard a dull sound of footsteps, and he immediately stopped and held his breath.

A huge monster beast appeared in front of his eyes. It was tall, covered in hard scales, and its eyes revealed a hint of cunning and cruelty. This is the legendary invincible, the Heavenly Demon.

Lin Tianxin clenched the weapon in his hand, ready to start a life-and-death struggle with the invincible. He knew it was going to be the toughest fight of his life, but he was determined not to back down.

The battle began, and Lin Tianxin and Invincible started a fierce fight. Their figures intertwined in the cave, and each collision brought a huge impact. Lin Tianxin was injured all over his body, but he still persevered and refused to give up.

Time seemed to stand still, and every second seemed as long as a year. Lin Tianxin felt that his strength was gradually exhausted, and his body had reached its limit. But he knew that he could not fail, he had to overcome invincibility.

The demon beast let out a roar and pounced on Lin Tian. Lin Tian quickly dodged while using his sword to block the demon beast's attack. He used the power of the demon beast to guide it into the valley.

The space in the valley is very small, and the attack power of the demon beast is limited. Lin Tian took the opportunity to launch a fierce attack, and the sword light flickered, stabbing at the demon beast like lightning.

The monster let out a scream, but it wasn't defeated. It pounced angrily at Lin Tian, and Lin Tian had to dodge again. He knew that he had to find a more effective way to deal with the monsters.

He decided to use his spiritual power to launch a powerful attack. He concentrated the strength of his whole body and condensed a powerful ball of energy. He threw the orb of energy at the beast and stabbed it with his sword.

Lin Tian clenched the sword in his hand, concentrating on vigilance. He knew that this battle would be a test of life and death for him.

Lin Tian's body stood straight on the battlefield, his gaze locked on the invincible body in front of him. Invincible is a huge monster whose body towers into the sky and exudes an aura of terror. Its skin is as hard as iron and seems incapable of being destroyed by any attack.

However, Lin Tian was not afraid. He was convinced that his spiritual power could overcome everything. He closed his eyes and began to gather his strength. His body began to tremble slightly, and the air around him became tense. A powerful energy began to gather in the palm of his hand.

The ball of energy gradually formed, and it emitted a dazzling light. Lin Tian felt the power contained in the energy ball, and he knew that this blow would be his most powerful attack. He gripped the ball of energy, ready to throw it at Invincible.

At this moment, Invincible suddenly let out a deafening roar, and its body slammed towards Lin Tian. Lin Tian immediately realized that the time had come for his attack, and he quickly threw the energy ball towards Invincible.

The ball of energy roared out and sliced through the sky. It went straight for invincibility like a shooting star. Seeing the energy orb's attack, Invincible let out an angry roar and tried to crush it with his huge claws. However, the energy ball exuded a powerful attraction that drew the invincible claws to it.

Seeing this, Lin Tian immediately seized the opportunity. He quickly rushed towards Invincible, the sword in his hand piercing Invincible's vital point. The sword light flickered, and Lin Tian's attack speed was extremely fast, almost making it difficult to catch.

Feeling the threat of the sword, Invincible let out a painful roar. It tried to break free from the energy ball, but to no avail. The power of the energy orb grew stronger and stronger, holding the invincible firmly in place.

Lin Tian kept attacking, and his sword light flickered. Each of his stabs hit the invincible's vital point with unmistakable accuracy, leaving the invincible in agony. Cracks began to appear in the invincible's body, and blood gushed from the wounds.

However, Invincible did not fall there. It let out a roar of rage, and its entire body emitted a powerful dark energy. The dark energy spreads rapidly, engulfing everything around it.

Lin Tian felt the threat of dark energy, and he immediately stopped attacking. He knew that if he continued to fight, he might be consumed by the dark energy. He needs to rethink the tactics of the battle.

Lin Tian quickly retreated, away from invincibility. He began to observe the actions of the invincible, looking for its weak points. Although the invincible body is powerful, its speed is relatively slow. Lin Tian decided to take advantage of this and look for an opportunity to attack again.

He waited for the time to come while adjusting his form. He took a few deep breaths and focused his mind to the highest point. He knew that this attack would be the difference between victory and defeat.

Finally, the time has come. Invincible let out another roar and pounced on Lin Tian. Lin Tian immediately stepped forward, the sword in his hand flashing with cold light. He accurately stabbed at the invincible weakness while using his spiritual power to unleash a powerful attack.

Invincible let out an earth-shattering roar, instantly unleashing powerful demonic power. Lin Tian felt the tremendous pressure, but he didn't flinch, but instead aroused the fighting spirit in his heart.

A fierce battle ensued between the two. Lin Tian nimbly dodged the invincible attacks while constantly launching his own attacks. His swordsmanship is like a storm, and each sword carries an incomparable power.

However, the invincible power was too powerful, and Lin Tian's attack did not cause much damage to it. He felt that his strength was gradually declining, but he did not give up, he knew that only by persevering to the end could he have a chance to defeat invincibility.

Just when Lin Tian was exhausted, he suddenly felt a powerful surge of energy into his body. His body instantly regained its strength, and he felt as if he was connected to heaven and earth, possessing infinite power.

He waved the sword in his hand, emitting a series of fiery sword qi, pointing directly at the invincible vital point. Invincible let out a scream, and his body began to shatter, eventually turning into a pool of black-red blood.

Lin Tian is victorious! He proved his strength by defeating the legendary invincibility. He felt that his cultivation had made a breakthrough, and his heart was filled with joy and pride.

However, just as he was about to leave, a voice suddenly rang out: "Congratulations, warrior, you have successfully defeated Invincible." ”

Lin Tian was stunned for a moment, he looked around, but found no trace of anyone. His heart moved, and he knew that this voice came from the invincible demon beast.

"Invincible, you're not dead yet?" Lin Tian asked in surprise.

"Yes, warriors. I didn't die, because I wasn't really a monster. The invincible voice sounded again, "I am a cultivator who was once sealed here. Only by defeating Me can you attain true strength. ”

After Lin Tian heard this, his heart was full of understanding. He understood that this challenge was not to test his strength, but to allow him to comprehend the true meaning of the path of cultivation.

"Thank you, Invincible." Lin Tian said respectfully, "It was you who made me understand the true meaning of the path of cultivation. I will continue to work hard to cultivate and become a true cultivator. ”

After speaking, Lin Tian turned around and left the Heavenly Demon Mountain and embarked on a new path of cultivation. He knew that this was just a starting point on his path of cultivation, that he still had a long way to go, and that more challenges awaited him.
