[Travel between the inner and outer worlds, magical beasts and other races, magic-summoning style, skill-based companion System (not a mindless System). The story isn't mindless, but it is a power fantasy. The villains are clever, the protagonist is intelligent, and he is ruthless when decisive action is needed. Read with care if that bothers you.]
The inner world invades reality, overturning the rules of the world. Humanity enters an era where magic reigns supreme.
A dimensional rift disaster! Other races and beast hordes run rampant!
Humanity's numbers dwindle. People can only scrape by in base cities!
Resources come hand in hand with slaughter, and opportunity walks alongside death!
Only by awakening as a hunter can one stand against magical beasts and reach the pinnacle of the world!
Su Chen, once the strongest Special S-Class hunter, had the only unique profession: Nether Spirit Singer. He could summon countless undead to fight for him!
Yet even after using up his one chance to exercise his Candidate authority, he still failed to save humanity from its greed and infighting.
[The Voice of the World announces: Special mission: Awaken the human race (0/1). Failed!]
[Candidate, I told you before: relying on human nature is absolutely impossible. You can only rely on yourself.]
[One opportunity to use the Candidate's time authority remains. Restart time?]
After returning reborn, Su Chen's memories were partially sealed, and his strength had fallen back to that of the weakest, F-class hunter. He could only depend on his younger sister and barely hold on to their place in the base city.
Forced to start over, he decides to live only for himself and his sister.
He rebinds the skill: Voice of the World, and becomes a Nether Spirit Singer!
Summon souls without limit, level up without limit!
Greatsword knights, skeletal undead, beautiful fox demons, divine spirit beasts, demon dragons, ferocious gods and evil spirits...
"I command life and death..."
"I am a god!"
"This is my army of nether spirits!"
"Rise!!!"
It's really well written. I hope the author can hurry up. It's rare to find a good work that suits my taste. Stand up and read more!!!
