After Zhang Heng and Miss Succubus signed the oath, they first contacted the beach pants man at the game point and spent 20 points to ask him to help them deal with the aftermath.
Although the man and woman hadn't died yet, based on the instant death characteristic of the dream of death, they should have no chance of surviving. In fact, their time of death was even shorter than Zhang Heng had expected, the process from drooling to losing their breath took less than 20 minutes. This also confirmed Zhang Heng's previous speculation. In order to prevent their identities from being discovered, the group of foreigners, committed suicide after failing the mission.
By the time the beach pants uncle drove the refrigerated car to the hotel, the two foreigners had already become corpses.
