Du Ze, a commercial investigator struggling at the bottom of the magic city, accidentally absorbed the blood of a huge green tree (actually a druid's sacred tree: oak) in the back of his hometown when he returned to his hometown, and was bound to become the master of the sacred tree space! This awakened ancient tree gives him the magical ability: swallow an acorn and collect the genes of an animal to transform into that animal!
Du Ze, who is very economical, prefers homing pigeons - feathers are easy to obtain and come with a "biological GPS". Transformed into a gray-feathered homing pigeon, he easily completes difficult derailment investigations and can even operate hidden cameras with his beak! Ability brings about a turning point, and also attracts the curiosity of beautiful colleague Xia Weiwei. The urban fantasy adventure of an ordinary investigator begins here!
