In a world dominated by countless races. Dangers lurk everywhere. Humans make contracts with other races, to gain greater power, to grow together.
In some corner of the world, long lost in river of time, Yang Feng transmigrated.
"My contract beast is the lowest level silkworm?"
"Where is my golden finger"
Two books appeared in front of him
Yang feng said tremblingly, "these, these can't be my golden fingers."
Only time will tell, how would the world change because of Yang Feng.
Will it prosper
or perhaps
Destroyed.
