Fang Xiao silently listened to the mysterious man's last words, his heart full of doubts and confusion. He didn't understand why he had become a legendary warrior, or why the Flame Greatsword had become the source of his power. However, he knew that this was not the time to think, and he had to leave this secret room first to find the clues to the answer.

Fang Xiao put the Flame Giant Sword into its scabbard and turned around to leave the secret room. However, just as he turned around, the door of the secret room was suddenly blocked by a powerful force. Fang Xiao turned around in surprise, only to see that the mysterious person's body suddenly turned into a cloud of black smoke and slowly dissipated into the air.

Fang Xiao felt a panic in his heart, and he felt that the atmosphere in this secret room had become extremely strange. He quickly drew his flaming greatsword and looked around warily. Suddenly, a dark figure flashed out from the corner and rushed towards Fang Xiao.

Fang Xiao immediately caught up, and the flame giant sword turned into a blazing light, intertwined with that figure. The collision of the two made a loud roar, and the entire chamber was shaken. The power of Fang Xiao's whole body was concentrated on the Flame Giant Sword, and he could feel the mysterious power contained in the sword constantly surging.

As the battle progressed, Fang Xiao gradually discovered that this figure turned out to be a person who looked very similar to him. His heart was full of doubts, could this person be a copy of him? However, he did not have time to think about it, the enemy in front of him was getting stronger and stronger, and he had to go all out.

The battle lasted for a while, and Fang Xiao gradually found himself at a disadvantage. He felt his strength draining while the other seemed effortless. Fang Xiao was anxious in his heart, he had to find the other party's weakness in order to turn the situation around.

Just as Fang Xiao was about to launch the final blow, he suddenly remembered the mysterious man's last words. He remembered what the mysterious man had said, "The Flame Greatsword is the source of your power," and he began to understand something. He decided to let go of confrontation and instead try to communicate with the other side.

Fang Xiao stopped what he was doing, trying to communicate with the person who looked similar to him. He lowered his weapon and walked towards the other side, trying to convey his intentions.

"Who are you?" Why do we look so similar? Fang Xiao tried to ask calmly.

That person stopped attacking and looked at Fang Xiao, a trace of doubt flashing in his eyes. After he was silent for a moment, he finally replied, "I am your brother, named Fang Ye. We are twin brothers, but our fates are very different. ”

Fang Xiao was shocked when he heard this answer. He had never heard of a twin brother of his own, let alone that they would meet on such a battlefield.

Fang Ye continued, "Our father was a great warrior who once possessed a legendary Flame Giant Sword. This sword represents the glory and strength of our family. Unfortunately, however, the sword was lost in a battle. My father left us in search of it and never returned. ”

Fang Xiao listened to Fang Ye's words, his heart was full of complicated emotions. He began to understand that the similarity between himself and Fang Ye was not accidental, but derived from their common bloodline and family heritage.

"So, why are you fighting me?" Fang Xiao asked.

Fang Ye replied with a wry smile, "I once heard that the Flame Giant Sword would only choose one true successor. I always thought that person was me, but when I saw the flaming greatsword in your hand, I realized that I was wrong. You are the real heir, and I am just a substitute. ”

When Fang Xiao heard this, a wave of sympathy surged in his heart. He understood Fang Ye's pain and loss, as he himself had experienced similar confusion and struggle.

"Fang Ye, we don't need to fight each other. We are brothers, and we should unite in our quest to find the Flaming Greatsword, find our father, and solve this mystery. Fang Xiao tried to convince Fang Ye.

They travel through this strange world, constantly encountering all kinds of fantastical creatures and mysterious powers. Sometimes, they will meet some friendly creatures and get their help and guidance; Sometimes, they will also encounter some vicious monsters that need to be defended by the power of the Flame Greatsword.

During their adventures, Fang Xiao and Fang Ye gradually discovered that every corner of this world hid a legend about the Flame Giant Sword. They met a wise man who told them that to fully unleash the power of the Flame Greatsword, they needed to find three sacred flame gems, representing courage, wisdom, and faith.

Fang Xiao and Fang Ye decided to embark on a journey to find the Flame Gem. They crossed forests and rivers to an old abandoned castle. There was an air of mystery in the castle, and they explored it cautiously. Eventually, in the basement of the castle, they found the first flame gem, which represented courage.

Next, they came to a mysterious cave. The cave was full of mist and sinister traps, but Fang Xiao and Fang Ye did not flinch. They support each other and move forward. Eventually, they succeeded in finding a second flame gem, which represented wisdom.

Eventually, they came to a sacred temple. There was a solemn and sacred aura exuding from the temple, and Fang Xiao and Fang Ye's hearts were filled with awe. They knelt in front of the temple and prayed silently. Suddenly, a beam of light shot out from the center of the temple, illuminating the entire temple. Fang Xiao and Fang Ye raised their heads and were pleasantly surprised to find that they had found the last flame gem, which represented faith.

With the three Flame Gems in their possession, Fang Xiao and Fang Ye felt a powerful force surging through their bodies. They decided to return to the starting chamber and unleash the flaming greatsword completely.

Back in the secret room, Fang Xiao and Fang Ye placed the three flame gems on an altar. Suddenly, a flame emerged from the altar, and the flames gradually fused together to form a huge flaming greatsword. Fang Xiao and Fang Ye felt the power of the Flame Giant Sword, they gripped the hilt tightly, and the flames on the sword body instantly burned.

"Stop! There is no need for us to keep fighting! Fang Xiao shouted loudly.

The figure stopped attacking, his eyes revealing a hint of confusion. Fang Xiao continued: "If there is any misunderstanding between us, we should cooperate, not confront each other. ”

The figure was silent for a moment, then finally nodded. He let down his guard and walked in front of Fang Xiao. Fang Xiao looked at him and found that there was a familiar light in his eyes, as if there was some kind of special connection between them.

"I'm Fang Xiao, who are you?" Fang Xiao asked tentatively.

The figure smiled slightly and replied, "I am Fang Xiao, but not the Fang Xiao you know. ”

Fang Xiao looked at him in amazement, and all kinds of speculations and questions surged in his mind. Could it be that they are the existence of parallel worlds? Or is it time and space confusion? Fang Xiao felt that his thoughts were a little confused, but he knew that now was not the time to think, they had to leave this secret room and find the clues to the answer.

The two Fang Xiao explored the secret room together, looking for clues. They found an ancient book with a legend about the Flaming Greatsword. It is said that the Flame Greatsword is an artifact capable of connecting different worlds, and its power is derived from the God of Flame. Only when Fang Xiao of the two worlds gathered together could he fully unleash the power of the Flame Giant Sword.

Fang Xiao and the other Fang Xiao glanced at each other, they both knew in their hearts that their fates were closely linked. They decide to work together to break the blockade of the Secret Room, leave the place, and continue their adventure.

After some hard work, the two Fang Xiao finally succeeded in opening the door of the secret room. They walked out of the secret room and into a strange and mysterious world. This world is full of fantastical creatures and mysterious powers, and Fang Xiao decided to move on to find more clues and answers.

Fang Xiao's heart moved, and he realized that all this was not simple. He began to scrutinize every corner of the chamber for clues. Suddenly, he noticed a portrait on the wall, and the figure in the portrait was none other than himself. Fang Xiao approached the portrait, looked closely, and found that there was a hidden button behind the portrait.

He pressed the button, and the wall slowly moved away, revealing a passageway. Fang Xiao walked into the passage without hesitation, the passage was getting darker and darker, and he could only rely on the faint light of the Flame Giant Sword to move forward. Finally, he came to a huge underground chamber.

The secret room was filled with all kinds of ancient weapons and treasures, but Fang Xiao's gaze was attracted by a huge stone platform. The stone platform is inlaid with a mysterious stone tablet filled with ancient texts.

Fang Xiao approached the stone tablet and carefully observed the words on it. He discovered that these words were not ordinary words, but an ancient rune that seemed to have special powers. Fang Xiao's heart was filled with curiosity and excitement, and he decided to study the meaning of these runes.

He began to carefully compare the runes on the stele with the ancient words he had learned before, hoping to decipher the secrets. After some hard work, Fang Xiao finally succeeded in deciphering the meaning of some of the runes. The runes seem to describe a mystical ritual through which it is said that endless power can be attained.

Fang Xiao's heart moved, and he decided to try this ritual. He followed the instructions on the stele and began to prepare the required materials and steps. He found some special herbs and ores in the secret room, as well as some mysterious utensils and magic items.

Fang Xiao carefully arranged these materials and began the ritual according to the instructions on the stone tablet. He lit a bouquet of incense and placed the herbs in a silver stove, allowing the aroma to fill the chamber. Next, he placed the ore in a specific position to form a peculiar pattern.

Fang Xiao took a deep breath, closed his eyes, and began to silently recite the spell in the rune. He felt a mysterious energy flow through the chamber, gradually converging around his body. His heart beat faster, and his whole body seemed to be wrapped in an invisible force.

Suddenly, the atmosphere in the chamber changed. A ray of light shot out from the stone tablet and illuminated the room. Fang Xiao opened his eyes, and an illusion appeared in front of him. In the vision, he saw an ancient temple with a divine aura.

Fang Xiao followed the illusion and entered the temple. He saw a large idol of a god with words similar to the runes on the stone tablet. Fang Xiao approached the idol and felt a powerful force emanating from the idol.

Suddenly, the eyes of the god statue began to glow dazzlingly, Fang Xiao was shrouded in light, and the whole person seemed to be integrated into the god statue. He felt a power that he had never felt before, and his body was filled with endless energy.

When the light dissipated, Fang Xiao found that he had returned to the secret room. He felt extremely light in his body and quick in his mind, as if he had gained extraordinary strength. He realized that this ritual really did give him endless power.

Fang Xiao decided to keep this ritual a secret, he knew that if this power fell into the wrong hands, it would bring disaster. He decided to reseal the runes on the stele so as not to cause unnecessary trouble.

However, Fang Xiao didn't know that his actions had already attracted the attention of some people. While he seals the runes, a mysterious organization learns of the ritual's existence. They crave this endless power, and they will stop at nothing to achieve their ends.

This organization sent an elite team to track Fang Xiao's whereabouts. They used various means to find Fang Xiao's whereabouts and tried to seize the power from him.

Fang Xiao felt the presence of the tracker, and he knew that he was in danger. He decided to use his power to protect himself and those around him.

A fierce chase unfolded. Fang Xiao used his strength to defuse the tracker's attack, while also showing his combat skills. He constantly dodges and counterattacks, engaging in a life-and-death struggle with his trackers.

After a fierce battle, Fang Xiao successfully escaped the encirclement and interception of the trackers. He understood that he had to find a way to control his power so as not to attract the attention of others again.

Fang Xiao decided to find a wise man, hoping to get some guidance. He had heard of a wise man who lived in the mountains far from the hustle and bustle of the world, possessing extraordinary wisdom and knowledge.

Fang Xiao embarked on a journey to find the wise man. He traveled through dense forests, climbed steep mountains, and finally came to the abode of the wise man.

The wise man was not surprised by Fang Xiao's arrival, he seemed to have foreseen all this. The wise man told Fang Xiao that the power he had gained was not something that ordinary people could easily control, and that it required a process of careful consideration and cultivation.

The wise man taught Fang Xiao how to use his strength and how to maintain inner peace and firmness. He told Fang Xiao that power was not an end, but a tool that should be used to benefit others, not abused.

In the secret room, Fang Xiao began to perform the ritual. He lit some special spices, placed herbs and ores into the vessel, and followed the instructions in a series of incantations and movements. There was an aura of mystery throughout the chamber, and the glimmer of the Flame Greatsword became brighter.

As the ritual progressed, Fang Xiao felt a powerful energy surging in the secret room. His body began to tremble, and his heart raced, as if connected to the power of the universe. He felt his consciousness gradually expand, merging into the existence of the entire universe.

Suddenly, a bright light shot out from the stone tablet, illuminating the entire chamber. Fang Xiao felt that he was attracted by an invisible force, and he involuntarily walked towards the stone monument. When he touched the stele, a powerful energy poured into his body.

His body was instantly wrapped in a layer of dazzling light, as if it had become a living beam. He felt his strength growing, and his body became unusually light, as if he was able to fly.

Fang Xiao looked up and found himself in a mysterious space. All around is a vast starry sky, shimmering with all kinds of strange stars. He felt as if he was at the center of the universe, and he could feel the pulse of the universe and the existence of life.

In this space, Fang Xiao saw a huge energy vortex. The center of the vortex emitted an incomparably powerful energy fluctuation, as if it was the source of the universe. Fang Xiao was attracted by this energy and involuntarily flew towards the whirlpool.

As he approached the whirlpool, he felt a powerful suction force bind him tightly, as if it was about to consume him. But Fang Xiao didn't feel frightened, his whole body emitted an energy fluctuation that echoed with the vortex, merging with each other.

As Fang Xiao merged with the whirlpool, his consciousness expanded further, and he began to see the mysteries of the universe. He has seen the birth and destruction of countless galaxies, the rise and fall of life on the planet, and the intertwining and change of time and space.

In this torrent of the universe, Fang Xiao felt that his existence had become insignificant, and he began to think about the meaning of life and the order of the universe. He understands that his power is only an insignificant part of the universe, and he should use his power to maintain the balance and harmony of the universe.

When Fang Xiao broke away from the whirlpool, he found that he had returned to the secret room. But at this time, the secret room had changed dramatically, the walls were inlaid with glittering gems, and the ground was painted with intricate runes, and the whole space exuded a sacred and solemn aura.

Fang Xiao felt that his body had undergone tremendous changes, and his strength and perception had reached a new level. He was able to feel the flow of energy from everything around him, and he was able to see the world hidden outside of reality.

He decided to use his newfound powers to discover more secrets and truths. He left the Chamber of Secrets and returned to the real world. But he knows that his fate has been closely linked to this mysterious underground vault.

Fang Xiao began to look around for clues, hoping to find more information about this secret room and the stone tablet. He visited many ancient documents and legends, came into contact with various mysterious organizations and characters, and searched for the truth hidden behind the world.

In the course of his exploration, Fang Xiao discovered an ancient secret book, which was said to have been left by a legendary master. This secret book records a magical ritual that is said to open the door to a world hidden from reality. Fang Xiao decided to give it a try, hoping to find more clues about the secret room and the stone tablet.

Following the guidance on the cheats, Fang Xiao came to an ancient altar. He lit the candles, arranged the offerings, and began the ritual. With his incantations and gestures, a sudden light appeared on the altar, enveloping him.

Fang Xiao felt as if his body had been brought into a new dimension. He saw a huge library filled with all kinds of old books and documents. He walked into the library and began to look for information related to the secret room and the stone tablet.

In the corner of the library, Fang Xiao found an ancient manuscript. He opened the manuscript and found that it contained the origin and function of the chamber. It turns out that this chamber was built by an ancient wise man to protect an important treasure. The stele is the entrance to the chamber of secrets, and only those with special abilities can enter it.

Fang Xiao continued to look through the manuscript and found a description of the treasure. The treasure is known as the "source of life" and is said to possess infinite power that can grant immortality to humans. This news shocked Fang Xiao, and he realized the value and importance of this treasure.

However, the exact location of the treasure is not detailed in the manuscript. Fang Xiao decided to continue exploring and looking for more clues. He left the library and came to a mysterious cave. According to legend, this cave was a place where an ancient wise man cultivated and where he hid his treasures.

Fang Xiao entered the cave and found that it was full of various traps and traps. He carefully avoided the trap and moved forward step by step. Eventually, he made his way to the deepest part of the cave and found a huge stone door.

Fang Xiao pushed open the stone door, and a huge treasure trove appeared in front of him. There were all kinds of precious treasures in the treasure house, but Fang Xiao's gaze was only attracted by a special container. This container looked ordinary, but Fang Xiao could feel the powerful energy it emanated.

He cautiously opened the container, and a gem that shimmered with brilliance appeared. This gem is the legendary "source of life". Fang Xiao felt his heart beat faster, and he realized that he had finally found the treasure.

In the course of his quest, he gradually discovers a vast conspiracy. It turns out that this underground chamber and stone tablet are the remains of an ancient mysterious organization that has been pursuing a power that surpasses humanity. They hope to change the order and pattern of the world by mastering this power.

Fang Xiao approached the stone tablet and carefully identified it. He discovers that these texts are an ancient one that only legendary warriors can understand. He touched the stele with the touch of his heart, and suddenly, the stele emitted a dazzling light, enveloping Fang Xiao in it.

Under the illumination of the light, Fang Xiao's consciousness entered a mysterious space. He saw an ancient warrior who was none other than the creator of the Flame Greatsword. The warrior told Fang Xiao that the Flame Greatsword was created by his hard work and wisdom, and that it possessed endless power and the power of justice.

The warrior told Fang Xiao that the reason he was chosen to become a legendary warrior was because he possessed a pure heart and endless courage. The Flame Greatsword is his trial, and it is only through fighting and growing that he can truly master the power of the Flame Greatsword.

Fang Xiao listened attentively, and he understood his mission and responsibility. He decided to take on the challenge and become a true legendary warrior who would protect the peace and justice of the world with the power of the Flaming Greatsword.

When Fang Xiao woke up from the mysterious space, he found that he had returned to the secret room. He felt that the power in his body was unusual, and he knew that he had earned the approval of the Flame Greatsword.

Fang Xiao left the secret room and embarked on his legendary journey. He slung the flaming greatsword around his waist and began his adventure. He will face all kinds of powerful enemies and difficulties, but he believes that as long as he insists on justice and courage, he will be able to overcome everything.

During his adventures, Fang Xiao met many like-minded partners, and they fought side by side to protect peace and justice. They have gone through countless battles and trials, but they never give up and always stick to what they believe in.

In the end, Fang Xiao and his companions successfully defeated the evil forces and restored peace and tranquility to the world. They became a symbol of legendary warriors and were revered and worshipped.
