Review Detail of Mr_Shang in Epic of Caterpillar

So, if i may, i just started reading this and i found couple of things that i dont understand, the water spear in the very first chapter, th MC said he uses almost all of his mp just to create one, and the next day she just throw it all around like its not even cost his mp at all, and how do mp exactly work? How much is every spell actuallt cost? Because the novel just mention the mp when it started to ran out, so i don't understand how much is 43 mp actually is, like, how many spell can he cast with 43 mp, Well that aside, i just read a couple of ch, hoping that all of that will be answered in the next chapter, just a suggestion for me if you'll make another novel is that in the very first chapter, maybe you want to put more attention to how exactly the system works, like making an comparison, to how strong is 40 Strenght, maybe you can explain that 40 Strenght can pull 100 kg, or lift a tree Weight 150 kg, or say that 40 Strenght is 4x normal human Strenght normal human have in earth, so that the "numbers " In the system actually means something and we, AS a reader can picture how strong is the character in the novel, and we can relate more, if you just do a number and without an further explanation, its become really boring and pointless if the number goes up, because we can actually understand how strong is the number, maybe if you go 100 speed you can run in the same as a car ( 100 km/h) or some Sorry for my bad english, i just read another novel when the number in the system literally become useless, its just going through the roof and we don't understand how strong its actually is
