In many cases, visual novels are indeed rated by CERO. CERO provides a standardized rating system to determine the suitability of the content for different age groups based on various factors like violence, sexual content, and themes.
I'm not entirely sure specifically what the 'cero essence anime story' is about as it's not a widely known common title. It could be a very niche or self - created anime concept.
In many anime stories, Cero Essence could be acquired through interactions with powerful characters or by uncovering hidden locations. Sometimes, it requires solving complex puzzles or fulfilling certain conditions related to the plot.
Since we know so little about the 'cero essence anime story', it's difficult to say who the main characters might be. However, in most anime, there are characters who are central to the plot because of their relation to the main concept. So in this case, if the 'cero essence' is important, there might be a character who discovers it, or perhaps a character who is born with it. There could also be antagonists who want to use the 'cero essence' for their own malicious purposes.
Hollow Knight was an independent game developed by three people. It used insects as the theme to build a huge and complicated underground world.

The specific game strategy and sequence recommendations could be found in the relevant game strategy guide.
If the branch is hollow, we can conclude:
1. If the branches are hollow and the leaves turn yellow and fall off, this may be due to the destruction of the branch tissue or the rotting of the roots. If the situation was serious and the branch tissue had been destroyed, it would be difficult to save it and could only be discarded. If the branch was hollow but the trunk was still healthy, then there was still a chance to save it. The branch might germinate and grow again.
2. For other types of plants, such as pomegranate trees, dragon blood trees, and dragon beard trees, the search results did not mention how to deal with hollow branches. Therefore, based on the information provided, it was impossible to determine how to deal with the problem of hollow branches.
In summary, there was no clear answer to the treatment of hollow branches.
