The Rebirth of the Nine Tribulations Sword Lord

In his previous life, he was a sword master in the Tribulation Stage, but when he ascended to the throne, he was surrounded and killed by six major sects, and he died with hatred. After his rebirth, he became a useless outer disciple at the bottom of the sect. At the third level of Qi refining, everyone can be bullied. But no one knew that in this young body lived a master of swordsmanship who had practiced for three hundred years. In this life, he awakens the [Immortal Killing System] - you can become stronger by killing enemies, and the rewards for leapfrogging kills are doubled! During the sect competition, he sealed his throat with a sword. To seize the treasure in the secret realm, he fights one against ten. Three hundred demon soldiers surrounded him, and with one sword and one man, he killed the demon general until he became frightened. The former enemy is kneeling at his feet, and the identity of the former lover is a mystery. When the man behind the scenes finally showed up, he drew his sword and asked the sky - this sword can kill immortals and demons, living up to reincarnation!
