Cultivation of Immortality: Starting from the Sanctification of the Physical Body

I don't want to ask anything else. I'm just going to ask about the three pages needed to train the skin at the first level. The spiritual energy required to upgrade the three pages is 100, 200, and 300 at the beginning. In total, it consumes 600 spiritual energy, right? Then, the spiritual energy required to upgrade your book page to sixteen pages requires 1400+1500+1600 for the next three pages, which is a total of 4,500 spiritual energy. Why did you deduct the spiritual energy consumed to upgrade the skin training level by deducting the following pages, which consumes 4,500 spiritual energy, which is ten times the amount? Was your math taught by a physical education teacher? Presumably suppressing the protagonist? In this case, you might as well improve it when you have three pages, because the speed of acquiring spiritual energy will be reduced at that time. Okay now, it's like this. . . . Isn't it too obvious for you to suppress the protagonist? The author explains it, I wonder what you are saying!

Why do you have to do something special? You can't cultivate immortality without spiritual roots. You can be a big firebrand.

Some books put people off in the first chapter.
