Wang Yi transmigrates back with a whole arsenal of skills.

It has been fighting giant beasts from the deep sea for more than eighty years;

The physical abilities of ordinary people have generally evolved, and this evolution has been systematically classified into the “Five Stages of Beast Tamers”;
