Lin Jin, who transmigrated into the world of Detective Conan, discovered something amiss with his dreams. In one dream, he unleashed a barrage of attacks on Ran, but the next day, she lost her match due to a muscle strain. He dreamt that Eri Kisaki was investigating a case of female assault, and he offered to help, cooperating in reenacting the case, which gave Eri a breakthrough the next day. He dreamt that he trained with Sun Wukong, and the next day he had eight-pack abs. "It's a pity dreams are random, otherwise…" Lin Jin felt quite regretful.
