"It has nothing to do with you, it was my mistake to leave her alone in the hotel," He Teng didn't blame Xing Ye, but he did blame himself!
The people sent to investigate the hotel quickly returned, saying, "We found something! Last night, a hotel staff saw a suspicious cleaner pushing a large garbage bin away from the back of the hotel. Initially, the staff thought the cleaner was just taking out the trash, but later found it strange that they were doing it late at night instead of waiting until daytime."
"Did you find out who that cleaner was?" the three of them asked in unison.
"We did, it's Lan Song," said the man with a nod, "Lan Song impersonated a hotel cleaner, and the hotel also discovered that a spare room key was missing. It must have been stolen by Lan Song, who then took the opportunity at night to put sister-in-law in the bin and kidnap her."
