Lin Yuan became a researcher at the top secret research institute after time travel.

During the year-end assessment, when colleagues took out polygraphs, veritaserum, hypnotics, ecstasy and other inventions, Lin Yuan faced the major general examiner and took out a black hook lock with a blank expression.

Chief: What are you?

Lin Yuan: Ecstasy Lock!

As soon as this statement came out, everyone was shocked!

From then on, a scientific researcher specializing in the invention of the underworld was born.

What, can't find the infiltration force's den? Learn about the impermanence of black and white, and the bull's head and horse's face.
