Detective Conan: I Can Use Every One of Doraemon's Gadgets

[Transmigration + System + Invincible + Breaking Up Couples + Multiple Female Leads]

(The plot may be changed.)

Tian Yancen unexpectedly transmigrated into the Detective Conan world and got bound to a System that let him use every piece of 22nd-century high-tech equipment without restriction.

So what kind of sparks will fly when science meets Conan's brand of science?

Gin: "Who keeps working against the Organization?!"

Kaito Kuroba: "I'm the real Kaito Kid, so who is this Kaito Kid?"

Conan: "This makes no scientific sense!"

Vermouth: "Are you the Silver Bullet?"
