"Deep in the northern mountains of the Cadia Riverlands lies a quiet and peaceful village. This village is home to the legendary Tianyin Swordmaster Sect, and is also the place where Duan Meng spent his childhood perfecting his technique.
As soon as he was old enough to pick up a bamboo sword, Duan Meng was determined to become a great swordmaster. While everyone else was still sleeping, he would already be practicing hard, and would continue until the sun set and the moon was clear and bright.
He knew that the requirements for entering the Tianyin Swordmaster Sect were high, and so, after countless days and nights of training in the wind, rain, and snow, the gates of the sacred temple finally opened to Duan Meng. Soon, his extraordinary talent and obsession with swordsmanship attracted the attention of the leader, Master Longma, who was once a disciple of the Great Dragon and the spiritual leader of the Tianyin Swordmaster Sect. Under the guidance of Master Longma, Duan Meng soon exceled among his peers and became the leader of the new generation of students.
Over time, Duan Meng grew tired of the stoic life of personal cultivation in the mountains. His obsession with swordsmanship and his innate ambition made him eager to challenge stronger enemies so that he could create his own legend and spread it throughout the world like the legendary swordsmen that inspired his personal journey. However, Master Longma denied his request to descend the mountain.
""It is not time yet. You have not yet become a truly invincible swordsman."" The young and vivacious Duan Meng refused to go along with his master's point of view. He was confident enough in his own ability and hoped to improve his swordsmanship through constant combat alone.
In the following years, Duan Meng traveled all over the Cadia Riverlands, defeating one swordsman after another, including the adherents of the Dragon Altar. He kept climbing toward the title of ""The Best Swordsman"" without a single defeat.
This was until Duan Meng ran into a man who would become his ultimate rival, Zhixu. This man came from nowhere and had no teacher. His life was like that of a sword, perfectly formed and complete within itself.
In their battle, Duan Meng was defeated, utterly unable to even fight back. In order to one day defeat Zhixu, Duan Meng isolated himself in the mountains and threw himself into a painstaking training regimen for three long years.
At the end of these three years, Duan Meng felt ready to fight Zhixu again, and emerged from the mountains. But as fate would have it, his opponent had made even greater progress in these three years. He was defeated again, and his sword was even slashed in half by his opponent.
Duan Meng's repeated failure reminded him of his master's words: ""It is not time yet. You have not yet become a truly invincible swordsman."" However, Duan Meng knew that he had already done everything he could, and there was no way for the sword in his hand to become any faster or stronger.
In order to seek out a truly invincible swordsmanship style, Duan Meng left the confines of the Cadia Riverlands and journeyed throughout the Land of Dawn. During his travels, he overheard rumors regarding Laboratory 1718 - that they could stimulate the potential of the human body through artificial transformation, granting one more power. Duan Meng could not resist inquiring further. If this rumor were true, he might still stand a chance of reaching the very peak of swordsmanship. As long as he could become stronger, he was willing to do anything.
At this time, the evil scientists of Laboratory 1718 were also interested in this swordsman from the East. They were preparing a new augmentation project to create a human weapon. As soon as the two parties came to an agreement, an unprecedented transformation began.
After numerous experiments and operations, the project was finally successful, and a being with mechanical strength and human sword skills and sentience was born. But after waking up, Duan Meng had forgotten everything about himself, including his own name. He was then given a new code name by his creator: Saber. The sword of Laboratory 1718, Saber became a tool used for hunting down those stood against them.
Of course, this was all part of Laboratory 1718's plan. They intended on luring just the right person to help complete their human weapon plan. Once the transformation had been completed, Duan Meng, who once dreamt of reaching the very height of swordsmanship, no longer existed. Instead, the ruthless mechanical killer, Saber, was born.
Though his creators were convinced they had achieved great success, as time went by, the familiar moves, the feeling of holding his sword in his hands, kill after kill, day after day—something began to stir within Saber. As a warrior, he could not accept being reduced to the status of a mere killing machine, and could feel the memories buried deep in his mind fighting to be remembered once more. He began to question his own past and the meaning of his existence.
Late one night, tormented by shards of his memories, Saber severed the neural control implant in his head, destroyed the humanoid weapon project laboratory, and embarked on the long and lonely road of exile.
In the years that followed, Laboratory 1718 never gave up their pursuit of what they saw as a failed product. Through the constant fighting and wandering that followed, Saber was determined to rediscover his name and origin. The fragments of his memory constantly bubbled to the surface, guiding him to slowly find his past. There was one thing he was certain of - he knew he had not yet become a truly invincible swordsman, and that he still had a destined opponent awaiting his next challenge."
