(Time travel + apocalypse + decisive killing + no system)
Two years after traveling to Blue Star, Xia Zian's life was ordinary. Just when he thought he could continue to live like this, the end of the world came.
With the advent of the end of the world, another side of the world that he had never touched was revealed.
Zombies break out, and only extraordinary people with spiritual energy in their bodies can kill them.
Reiki can only be absorbed by those who practice breathing techniques.
Xia Zian obtained the peerless breathing method at the beginning, and then embarked on the road of surviving and becoming stronger by killing zombies and absorbing spiritual energy.
"Xia Zian, your breathing technique is too cunning, you actually stole my spiritual energy!"
"I'm sorry, senior, let me change my breathing method."
"What! You actually know other breathing methods?"
"Yes, there are seven more breathing methods like this!"
