Review Detail of Aquadiver289 in Stronger From A Sapling

This could be a really good story. I do love the concept, but the execution has not been that great. Granted, I am only about 30+ chapters into the story, but this is enough to give me pause about a number of issues. 1) Next to no character development from anyone. Even the MC at the very beginning didn't really have much emotion one way or the other when finding out he died and has been reborn with a system. 2) The MC is all about getting along with others when it is little girls, but is kill them all when it comes to anybody else. He does not take into consideration his followers feelings at all and just says 'get over it'. His subordinates have major issues with humans as they have killed the families of nearly everyone they know and the MC just does not care. Granted, this could be because he was human originally but it comes across as a little kid sticking his fingers in his ears while screaming, "Lalalalala!!! I can't hear you" so that he does not have to deal with the situation. 3)the MC is a pretty big pervert. While it never explicitly states how old the MC is, I get the impression of someone who is at least late 20s or older. Because he is a tree now, he thinks its perfectly okay to ogle 2 little girls who are bathing in the lake. From the wording of the chapters, I was under the impression of 10-11 year olds who looked like they were 13-14 years old. I might be wrong, but that is how it came across to me. 4)The grammar is not great. I would have to go back and reread certain sections a few times until I could finally piece together the meaning of the sentence. 5) I noticed that the author made it a pay to read starting at chapter 43. I am having issues getting through to chapter 33 without any real story or character development. I refuse to pay to read the rest of this. 6) There is no real guideline on how the MC can actually improve himself. What I mean by this, is that at the end of the very linear growth (at least where I am at), the system says he now needs to evolve. That is all well and good, but a chapter or two later, the MC decides to strengthen his roots and become immune to fire. At what point did the MC have the ability to perform this. It seemed to crop out of nowhere. I think this is all I have for right now. Again, I feel like this could be a really great story concept, but a number of issues need to be addressed.
