Xu Sheng transmigrates to a human tribe and wakes to find that the entire tribe, a million people strong, has been wiped out by the demon race.
Severely injured and too weak to even lift a chicken, Xu Sheng can only remain in the tribe. Just as he is on the verge of death, he awakens the "Draw Sword and Sever the Primordial Chaos System." The System rewards him with a congenital spirit body, saving his life.
The appearance of the congenital spirit body triggers a supernatural upheaval, prompting the Heavenly Venerable Yuanshi to consider taking Xu Sheng as a disciple. But as a human born after the creation of the world, Xu Sheng refuses to give up his human identity, so he cannot join the Chan Sect. Later, Zhao Gongming brings Xu Sheng into the Jie Sect.
"Look, what is he doing?"
"Judging by his stance, he must be practicing the sword-drawing technique."
"Really? His cultivation is only at the Earth Immortal level. Why practice drawing a sword instead of focusing on his cultivation?"
"I know him. Senior Brother Gongming brought him back from a human tribe. Like me, he joined the Jie Sect as an outer disciple a hundred years ago. He's been practicing this sword-drawing technique for a whole century!"
"No way! He's practiced one sword-drawing technique for a hundred years and still hasn't mastered it? What a useless talent!"
"Humans? That race the demons treat as food? With talent like that, I suppose it makes sense."
"Sword-drawing technique!"
Xu Sheng roars and suddenly draws his sword! Boundless sword intent erupts, raging across the heavens!
A century of enlightenment in the sword path!
That day, the world faced catastrophe, and humanity suffered a great calamity!
Xu Sheng alone, with a single sword, split the sky, shattered the earth, destroyed the Demon Saint, and slew the Demon Emperor!
