Sword Agreement: Symphony of East and West

He was once an abandoned son of a swordsman family, with E-level mental strength, unable to awaken even the humblest swordswoman. On the day when his engagement was broken up in public, everyone was laughing at him. Until he was about to die, the ancestral rusty iron fragment on his chest drained his blood and awakened a sleeping girl. "The pieces of Xuanyuan Sword's heart... Are at the disposal of the master." Everyone said that the sword was revealed from heaven and the king was given the power by God. He wanted to walk an ancient imperial path as a mortal. When the five famous sects came to question him with their epic swords, he said: Kneel down. When the Knights of the Western Covenant came to purify with the mythical sword, he said: Those who cross the line will be killed. Until Ragnarok, which had been sealed for thousands of years, awakened at the same time, and the Four Swords of the East to Kill Immortals merged with the Western Flame of Destruction. All sword masters in the East and West were in despair. Only the shadow of Sword Girl with Nine Famous Swords slowly emerged behind him. "Why are you panicking? Call someone." This is the story of a good-for-nothing boy who personally ended the old era of the sword covenant and created a new covenant between the East and the West.
