This is one of the best novel in this trial section(at least for me). So, this novel has cautious, mature & somewhat intelligent mc but what i like most about this novel is the dealing of mc with other character and how much chain reaction a single quest can have(which mc has experienced in past). Other side character also does not feel bland to me they are bit alive here. world background and cultivation is somewhat mystery but I think it will be introduced in future(initial phase of world background is shown and is surely better than many novels out there for 40 chapters).At the end of the day the novel is lighthearted(maybe), somewhat dark, mature, has some comedy, romance(don't know but will surely have) and character development(at least how the personality of mc matured over time due to his past is shown).

Bro its survival of fittest and adapting to environment does not means cowardliness and here he clearly states that he feels world is against him so it is just he is cautious and here it gives some more realistic feeling.
