Kai stayed inside the bush for two months to heal himself. He had enough food and water for him to last three months. It was his habit to store food, and because of that, he was able to live; otherwise, he would have died from hunger.
As a peak supernatural realm cultivator, Kai can survive without eating or drinking anything for a month, but if it exceeds that, it is hard to consider and in Kai's body condition it is certain death.
The food accelerated the healing process because it provided necessary nutrients to his body.
Kai is now capable of walking, but he can't do any work that puts strain on his body, or else the bones may break again.
Kai left the bush and started searching for a safe hideout.
'Why is this place desolate? I didn't see a single life form' Kai thought while walking. After searching for half a day, he finally found a good place to stay.
'This place might be good, and the location is also perfect for hiding.'
