As for this time, the situation was quite special. Zhang Heng completed the main task ahead of schedule before the given deadline.
The task of looking for the Lucky Horseshoes was automatically completed after meeting Cook and Matthew. Other than that, the task of settling down in Lincoln County was completed two weeks after he owned the ranch.
In other words, he did not need to worry about his quest anymore, and he could do whatever he wanted. And his life in the west had just begun. After redeeming his extra 24 hours, his time in the quest was extended to 520 days. Soon after taming Bad Boy, he also received the bounty that he was supposed to receive after killing Cook.
In total, killing Cook granted him ten thousand dollars. And the twenty Cook Gang members that he killed contributed another eight thousand dollars to him. In total, he bagged a satisfying eighteen thousand dollars.
