To be honest, Zhang Heng was never once lucky since he entered this dungeon. The first thing he did was kill an entire bar full of people to get himself a drink. But later, he found out that the people that he killed were related to his primary mission. Amid the search for Wendy's father, he encountered the old sheriff. Zhang Heng got into a massive fight with him because he insisted on sending Wendy home. When he arrived at his destination, he became embroiled in the conflict between local miners and farmers. Fortunately, his bad luck would seem to be finally over by tonight.
As soon as the sun went down, a large black cloud appeared in the sky, blocking the moonlight. It was very dark, and the visibility that night was very low. In other words, their plan's success rate for tonight had just gone up.
But to be cautious, everyone decided to wait another two hours before making their move.
