If they couldn't move on to the tomb, then getting Lin Yi's storage bag would make this trip worth it!
As for why Bai sanzhu and Huang si didn't do it themselves?
Of course, it was also because of their fear of Lin Yi. If the operation failed, Bai sanzhu and Huang si could push the blame to their men, just like how they were temporary workers in the secular world.
Besides, Lin Yi was a poison practitioner. Bai sanzhu and Huang si wanted his treasure, but they were afraid that they would die if they tried, so they sent their men to try first.
Bai sanzhu and Huang si seemed to be in deep sleep, but they were only pretending to be asleep. They were highly focused on the progress of the matter.
At first, the two of them were able to get close to Lin Yi without making a sound, reaching out to grab his storage bag at the same time!
It seemed that the two of them had not agreed beforehand who would take the treasure first, or it would be whoever got it first!
