Extremely Destroying Sword Immortal

Fang Yun traveled to a different world and became an outer disciple of Jian Yuan Pavilion, a sect of swordsmanship. He has no master and no background, but fortunately he has the plug-in optical brain necessary for time travel. Facing the complicated world, he set a small goal for himself - eternal life. Anyone who stands in my way on this road will die. A lost guest in the world of mortals, a sad song for the evil deeds of the sword. Find a way out of life in silence.
