Bai Yun woke up from his sleep only a week later. But even then, he still had a splitting headache. Soul injuries may not look serious, but they were extremely has to heal from. Thankfully Bai Yun had the number one soul cultivation technique in the universe, the experience of being a soul god, as well as enough pills.
When he woke up his soul injuries had pretty much stabilized. The bigger issue was the pill impurities in his body. But with the hundred beast flame and thousand poison immunity, it was only a solvable problem.
The only good thing that came out of this was that his soul had grown a bit. A few more days of rest and a few soul pills and his soul would be ready to break through.
