What are the amazing reasoning bridges in Star Detective?

It's also good to relive the first two seasons when the detective plays it again. It's definitely good for me to think directly in my head and leave a deep impression on me. Sasa, the tie appeared in the thermos cup (absolutely unreasonable). The murderer wanted to frame the captain. The murderer had a grudge against both the deceased and the captain. Why didn't he lock the trainee? This passage is really wonderful, but it's a pity that Sasha finally went astray. Sasha, the face of the deceased was completely burned, but the identity card only left the name and other contents, destroyed the body, left the dean for a year, had plastic surgery, and killed someone to change his identity. "Top of the Champions League" Sasa, the plug of the sink left blood, and the murderer was the last person to wash his hands. This reasoning is awesome, but it doesn't work. The original intention of the program group was that the murderer cleaned up the murder weapon and the blood on his hands. Unexpectedly, he spilled that layer, which made Xiaobai suspected that he was the last one to go to the toilet, and Xiaobai was drunk and didn't wash his hands.
