Detective Conan's Mixed Eating and Waiting for Death

It mainly tells that a China killer, Li Mingming (a child as big as Conan), broke through the Conan era, came to Conan's side as the nephew of Kogoro, rescued some kind-hearted murderers, and then became a killer in Conan's world, earned a lot of money, rescued Xiao Ai's sister, and fell in love with Xiao Ai and killed her. (See the ending for yourself)

If you love Conan very much, you'd better not watch it. Because Conan can compete with him except for his reasoning ability. The other Conan is like an idiot.
