Review Detail of D_Wolf in Immortality: My Spell Upgrades Infinitely

So this one has a more acceptable version of an upgrade type system. Most of the upgrade system stories require virtually nothing as a price for each upgrade. There are usually limits but those limits actually take away from the enjoyment of the story, mainly because the stories suggest unlimited upgrades. In this story the author takes an alternative approach to the upgrade type system. First off it seems that it is truly unlimited and infinite as the title suggests. To work with this each upgrade requires 'resources' to perform the upgrade. There does not seem to be any chance of failure, but acquiring the 'resources' for each upgrade can be time consuming as well as costly. I very much appreciate this approach to the infinite upgrade system concept. The story starts off with the MC transmigrating into a person who just was killed and he has some significant problems cultivating. He only has a pseudo spiritual root. while it is not the worst problem as he is a very poor individual with no real background he is not able to acquire the resources that are necessary to allow him to cultivate. That said he starts going the route of martial techniques. These as he upgrades them eventually allow him to break into the cultivation realms. Most if not all of his cultivation is done via his upgrade system. 'Resources' such as half a day of boxing, 10 teals of silver and a single soul essence are needed to upgrade initially. Each upgrade gets progressively more expensive in both time and money. In reality following the story seems to be a bit difficult, as it is rather confusing as to the progression of events. How does he get involved with this person, or what is the actual sequence. I appreciate this story for the system design, though the story-writing seems to leave a lot to be desired. I may decide to finish the first 40 but if the confusing nature continues I would not really be interested in continuing to read this one.
