Ten years ago, a red moon appeared inexplicably in the sky. The red moon built a wormhole connecting the earth and other worlds. Countless alien creatures poured into the earth. At the same time, the spiritual energy leaked from the other world gave birth to "Hunters" on the earth.
Hunter level 1--100.
Level 1--20 junior hunter
21-40 intermediate hunter
41 - Level 60 advanced hunter
61——Level 80 title level hunter
81——Level 100 palace level hunter
With the help of hunters, various countries on the earth have successfully dealt with attacks from alien creatures, and discovered that each copy of the alien "copies" that appeared on the earth contains a large number of alien crystals. Humanity has developed rapidly with the help of alien crystal technology, and hunters have become the most respected profession in society.
