Tracing back a thousand years was not an easy job even for a god. It was nothing serious if it was just to trace back to a fixed time and place, but what Sui Xiong had done was track his experience for a thousand years. That was something only possible for a powerful god like him. As for others, not to mention the mortals, even ordinary gods would be exhausted in the process.
Sui Xiong felt tired as well, so he decided to take a rest and wait for his spirit to recover before continuing to track his body.
Anyway, if his body was still somewhere in the sea, it had already been soaking in the water for a thousand years. It probably didn't care about soaking for another two or three days.
If his body was no longer there, what would be the difference between tracking now and a few days later? If his body had been eaten by a fish or swept away by sea water, he didn't know how long his tracking would take. Then, what did a few days' rest matter?
