What did Momo do to make Di Renjie see through it? What is that thing that drinks a bottle of blood every day?

A: 1. DOG showed a flaw when the assassin assassinated Liao. Di Renjie thought Momo saw a shadow, so he didn't put down the medicine pot and went after the shadow himself. Just go to the west wing and tell Di Chun. Isn't that unnecessary? So Di Renjie concluded that Momo was going to discuss countermeasures with the shadow. In addition, Di Renjie heard from Zhang Huan that she met Momo when she went to Cuihong Hospital to track Wang Qiang's dismissal. DOG claimed that she had come to get the medicine. Later, Di went back to the office to check the name of the drugstore where the medicine bag was placed, called Baicaotang, which was more than ten miles away from Cuihong Hospital. So Di Renjie knew Momo was an undercover gangster lurking around him. 2. That's a god of death, that is, a red bat. It sucks human blood and its brain marrow will mutate. It is produced in the desert of Hutart.
