The losses were secondary - not that Zhou Tian neglected them. However, given the current depth of Zhou Tian's power, losing those Bears wasn't enough to shake his foundation.
The real regret for Zhou Tian was the loss of a hard-won opportunity. Zhou Tian had failed to secure his footing on the mainland this time, and it was uncertain how long before he could have such an opportunity again. Without a stable footing on the mainland, Zhou Tian's desire to invade it was nothing but a pipe dream. Given this situation, Zhou Tian's mood naturally couldn't be good.
Regardless of Zhou Tian's unhappiness, things had developed to this point, and even his unwillingness couldn't change anything. Rather than lamenting the lost opportunity, Zhou Tian would do better to think about how to create a new opportunity to invade the mainland.
However, having suffered this setback, Zhou Tian had learned his lesson.
