White Divine Crane

This was an era where everyone could experience various worlds through simulations.
When everyone reached 16 years old, they would receive a Life Lantern, which would grant them two free simulations.
During the free simulations, they had to break through the limits of humans in order to attain a bright future in reality. 
Otherwise, they would lose their Life Lanterns and they would slowly be corrupted by a black fog until they eventually died at a young age. 
Lin Qiye, who transmigrated to this era, failed his first simulation.
During his second simulation, by chance, he acquired a permanent SSS-rank talent - the Deduction of Genesis.

[You carefully made plans before the spiritual aura rejuvenated. Because of this, you defied the heavens and successfully changed your fate. You acquired S rank in your evaluation. Your rewards are…]

The three-meter-long Leech Demons wriggled in the city. Their thousands of feet madly drilled into the crowd.

The Face-hugging Demon, the Snake Demon, and the Toad Demon, whose poison sacs kept exploding and even spat out lumps of flesh that looked like threadworms made people's scalps numb, and their hair stood on end.

"My fellow men! Follow me and kill all the demons!"

Tens of thousands of Practitioners soared into the sky and slaughtered the demons that passed through the city walls.
